    Scope of the Invention
    The present invention relates to a system and a method for determining an estimate of collision damage in a car. Specifically, the present invention relates to a computer system and a method implemented on a computer for determining an estimate of collision damage in a car, using a user interface to visualize a part of the car's body. Background of the Invention
    Typically, for car repair facilities, car insurance companies and damage experts, it is necessary to obtain an assessment of the damage to a car (ie an automobile) resulting from a collision. It is particularly important to efficiently and accurately determine an estimate of collision damage, including the time and/or cost to repair the damage to the car.
    US2006/0114531 describes a vehicle inspection station that uses multiple cameras to capture images of a car. To detect whether a car is damaged, at least a part of an image is compared to a previously saved image of the vehicle. However, the vehicle inspection station is not set up to assess the damage and/or provide an estimate for repairing the damage.
    US 5,839,112 describes a computerized insurance estimation system that can be used by experts in auto insurance and repair facilities to obtain information about parts, labor and repair operations for repairs of automobiles (cars). An application program displays various sections of the vehicle's outer layer, including car body parts such as the rear bumper, doors, rear and front fenders, and the vehicle's hood or windows such as the rear or windshield. - breezes. By clicking on the selection circles provided, the user selects one or more damaged parts of the vehicle. The estimate is based on selected vehicle parts and cost data, which defines for each part its purchase price and the labor cost involved in replacing the part. The system is not set up, however, to further determine damage to individual car parts.
    US 2004/0073434 describes a method and system for estimating automotive damage that can be fixed by repairing unpainted dents, that is, techniques for removing dents from the body of a motor vehicle when the paint is undamaged. Various parts of the vehicle are displayed in a user interface and the user can specify, for each part of the vehicle, a number of dents. Additionally, the size of the dents can be specified by the user by selecting one or more of the dent sizes illustrated. Damage information is communicated to a central computer, which creates a report including repair costs for the vehicle. The system allows you to determine different levels of damage to car body parts, but the definition of damage is limited to circular dents and a small number of certain sizes. Invention Summary
    This invention aims to provide a computer system and a computer-implemented method for determining an estimate of collision damage in a car, which system and method does not present the disadvantages of the prior art. Particularly, the present invention aims to provide a computer system and a computer-implemented method for determining an estimate of collision damage to a car, particularly a cost and/or time estimate for repairing the damage to a car, which system and method does not they are limited to giving prices or labor costs for individual parts of a car body or predefined shapes, shapes and sizes of dents.
    Note that the term "car" is synonymous with "automobile" and is to be understood broadly and is intended to include other wheeled motor vehicles not limited to passenger transport, but also goods, particularly light commercial vehicles. The terms "car body" or "car body" refer to the outer layer of an automobile exposed to collision by direct contact with an object outside the car.
    Correspondingly, the term "body part" of a car refers to components and panels of the outer layer of an automobile, including hood, fenders, panels, bumpers, grilles, vents, spoilers, door panels, handles of door, centering, reliefs, etc. and also glasses. The term "other car parts" or "more car parts" is used here to refer to any part or internal component of the car, which is not part of the car body but is found within the outer layer of the car and therefore Therefore, it is covered by the body or a part of the car body, respectively. The term "repair" is intended to include repairing a damaged part as well as replacing the damaged part with a new part.
    According to the present invention, the above mentioned objectives are achieved through the features of the independent claims. Furthermore, other advantageous models follow the dependent claims and description.
    According to the present invention, the above objects are particularly achieved by the fact that, when determining an estimate of the collision damage of a car, a car body part is displayed in a user interface, via the received user interface. of a user a contour of at least one damaged area is entered to define a body part, the damaged area is guided in the cup part according to the defined contour, and an estimate of the repair cost and /or repair time for the user, based on the damaged area drawn on the body part. Therefore, the collision damage estimate on a car includes the estimated cost and/or time to repair the collision damage as defined by one or more damaged areas defined and drawn on one or more parts of the car body. For example, there are selections of a car model and at least one car model body part received from the user interface, and the estimate is created as a function of the selected body part(s) of the selected car model. By providing a user interface to define and draw the outline of one or more damaged areas in a car body part, the user is given the possibility to efficiently, flexibly and accurately define regions of a car body part. that was damaged and shows a defect resulting from the collision. Allowing the user to define a damaged area or region by defining its outline on the body part in the form of a closed line, e.g. ex. as a freehand drawing or a set of line segments forming a polygon, the user interface allows you to efficiently, flexibly and accurately define collision damage on car body parts, without any limitation from the damaged areas to the predefined shapes, molds or sizes.
    Preferably, a drawing tool is provided in the user interface which allows the user to draw the outline of the damaged area on the body part. Therefore, the damaged area is defined by an outline of the damaged area drawn on the body part using a user interface drawing tool. Correspondingly, the drawing tool allows the user to enter inputs, through the user interface, in the form of a drawing, instructions for defining the contour and thus the contour, shape and mold of the damaged area or region in the body part. In another model, the user receives an image of the body part and the contour of the damaged area is detected from the image of the body part. Correspondingly, the user interface allows the user to input input to define the outline of the damaged areas in the form of photographs or digital images, which are scanned or uploaded to a computer system, respectively. Detecting the contour of the damaged area using an image processing contour detector allows you to very efficiently and precisely define the contour and thus the contour, shape and pattern of the damaged area or region in the body part. .
    In a model, the damaged area is positioned on the body part in response to user positioning instructions via the user interface. Depending on the model and/or user instructions, the positioning instructions define an initial starting point for drawing the outline of the damaged area or a destination location to which the outline of the damaged area is moved.
    In a privileged model, for the damaged area drawn on the body part, the user receives, through the user interface, an indication of an impact level and the estimation and function of the impact level for the damaged area is created. By setting the impact level for the damaged area, it is possible to flexibly and efficiently specify the severity and/or depth of damage in the respective region of the body part.
    In another preferred model, other parts of the car that have been impacted by damage to the body part are determined as defined by the damaged area drawn on the body part, and repair of these other parts is included in the creation of the estimate. Determining collision damage on other car parts, which are covered by the car body or body part, allows you to further increase the accuracy of the collision damage estimate.
    In a model, characteristics of the body part, including the thickness of the body part, the material of the body part and/or the repair accessibility of the body part, and these characteristics of the body part are determined from a database. body part are included when creating the estimate. Considering characteristics such as thickness, material, and repair accessibility of the body part, it is possible to further increase the accuracy of collision damage estimation, as these characteristics influence the time and cost to repair a part. of the body, as well as the probability that another part, which is covered by the respective body part, has been damaged through the collision.
    In another model, the procedures for repairing collision damage are created by the user, based on the characteristics of the body part, the body part damage is defined by the damaged area drawn on the body part, and other car parts that suffer the impact by damage to the body part as defined by the damaged area drawn on the body part.
    In addition to the computer system and computer implemented method for determining an estimate of car collision damage, the present invention also relates to a computer program product comprising a computer program code for controlling one or more processors of a computer system. , preferably a computer program product comprising a tangible computer readable and non-transient medium in which the code of the computer program is memorized. The code in the computer program is set up to make a computer system run the method for estimating collision damage on a car. Specifically, the computer program code is configured to cause the computer system to estimate the collision damage in a car to display a car body part on a user interface, receive instructions from a user from the user interface. to draw on a body part at least one damaged area, draw the damaged area on the body part in accordance with the instructions received by the user, and create for the user an estimate of at least one of the repair costs and times based on the area damaged drawn on the body part.

The contour detector 15 includes image processing modules to create the contour, e.g. ex. using corner detection and extraction algorithms to determine the contour of damaged areas from digital image data.
    Preferably, the functional modules are implemented as programmed software modules comprising computer code for controlling one or more processors of one or more computers. Preferably, the computer code is memorized on a computer readable medium, which is connected to one or more processors in a fixed or removable manner. Professionals in the field understand, however, that in alternative models, functional modules can be implemented totally or partially through hardware components, eg. ex. the contour detector 15 may include image processors to detect the contour of one or more damaged areas 5 from the image data.
    Depending on the model, computer system 1 is implemented as a stand-alone system, as shown in Figure 2, or as a distributed system, as shown in Figure 3.
    In the stand-alone version of Figure 2, the computer system 1 is configured to operate 10 independently of any external computer, server or database, and comprises a single computer that includes the functional modules, a display for the graphical user interface 100, elements input 101 and database 14. For example, the stand-alone version of the computer system 1 is a stationary personal computer (PC), a laptop PC or a (multi) touch-sensitive tablet PC such as an iPad® (iPad is a registered trademark of Apple Inc.). In the stand-alone version, the computer system 1 is connected to a communication network 2 only for the purpose of updating its functional modules (software) or the contents of the database 14.
    In the distributed version of Figure 3, the computer system 1 comprises two or more computers: one computer is implemented as a communication terminal 1a, 1b, 20 1c, while the other computer is implemented as an Id server. communication is a fixed PC 1a, a laptop PC 1b or a tablet PC 1c. As schematically illustrated in Figure 3, the communication terminal 1a, 1b, 1c is connected to the server 1d via a communication network 2. The communication network 2 comprises a fixed and/or portable communication network, including an area network. 25 site (LAN), digital subscriber lines (xDSL), a mobile radio network such as the Global System for Mobile Communication (CSM) or the Universal Mobile Telecommunication System (UMTS), a wireless LAN (WLAN) and the Internet, etc. While the database 14 is located or connected to the server Id, the user interface 10, including the display with the graphical user interface 100 and the data input elements 101, is implemented in the communication terminals 1a, 1b, 1c. Depending on the model, the estimator module 12, the operations generator 13 and/or the optional contour detector 15 are implemented and operate on the server 1d or on the communication terminals 1a, 1b, 1c. Correspondingly, the communication terminals 1a, 1b, 1c act as clients or web clients, while the Id server acts as an application server, a database server or a web server.
    Preferably, the database 14 is implemented as a relational database and/or other electronic data storage/population system with an indexed and/or hierarchical data structure and organization. The database 14 comprises data on specific models of cars (cars), including and individually distinguishing their various versions with different mechanical options. A car model is identified by brand and/or manufacturer name, model name, version number and/or unique identifier such as a model number. For each car model, the database 14 comprises data on the characteristics of all parts of the car body, e.g. ex. hood, mudguards, wheel arches, panels, bumpers, grilles, openings, spoilers, door panels, door handles, centering, reliefs, etc. Data about the body parts of a car model includes a name of the body part, an identifier of the body part, the material of the body part and its shape and dimensions, particularly its thickness and area that can be painted, its location in/on the car, its relative position and distance to other car parts covered by or attached to the respective body part and/or neighboring/adjacent body parts, and a graphical representation to visually create the part of body 3. In addition, data on a body part includes repair accessibility information, ie data indicating whether, and if so in what dimension and where, a body part or sections of the body part. body are accessible for collision damage repair, specifically if and where a platemaker, i.e. a bodybuilder, can place a maintenance cart on the back of the body part, facing the interior of the car, as an accountant to flatten the damaged area. the body part, using a hammer at the front of the body part, facing the outside of the car, or if and where other repair procedures that consume p. ex. more time. Depending on the model, data about a body part includes more part accessibility information indicating the interdependence of the body parts with adjacent or adjacent body parts and/or other car parts with respect to their removal, replacement and/or repair . Preferably, the database 14 further comprises, for each car model, data on other (internal) parts of the car, including a part name, a part identifier, part material/materials, its shape and dimensions, the its location in the car, its relative position and distance to body parts that are attached to or cover the respective part, and/or part accessibility information indicating the part's respective interdependence with neighboring or adjacent body parts and/or other car parts regarding their removal, replacement and/or repair. For body parts 3 and other car parts, the database 14 further comprises pricing information indicating current purchase or replacement costs. The database 14 further comprises for body parts and other car parts work items and operations including detailed procedures (including written text, images and/or video sequences) and indications of materials needed to repair, through repair or replacement, damaged body parts or other car parts for various levels of damage or impact. Database 14 also includes information on the cost and/or time required to carry out the individual work items, operations and/or procedures. In one model, the database 14 also stores time information, indicating for the body parts 3 and other car parts in each case the length of time required for their replacement. Furthermore, the database 14 comprises, for the body parts 3, the estimated time and/or costs required to (re-paint) the body part 3 or a defined area of the surface of the body part.
    In the following paragraphs, described with reference to Figures 4, 5, 6, and 7, there are 10 possible step sequences performed by the computer system 1 or its functional modules, respectively, to define the collision damage on a car by determining a collision damage estimate against estimated repair time and/or estimated repair costs. Reference is further made to Figures 8a, 8b, 9a, 9b, 9c, 10a, 10b, and 10c illustrating the display with the graphical user interface 100 for setting the collision damage on a car and showing the collision damage estimate .
    In step S1, the user of computer system 1 selects the model of the car with collision damage. In a model, the user defines the car model by entering the manufacturer or make of the car and selecting the specific model from a list that is returned by the computer system 1 from the database 14 and provided by the user. 20 In a model, the user enters one or more search terms that describe the car model and selects or confirms the specific model in a corresponding search result returned by computer system 1. Alternatively, the car model is determined by computer system 1 based on a photograph (digital image) of the car that is scanned or uploaded to the computer system 1.
    In step S2, for the car model defined in step 51, the user of the computer system 1 selects one or more parts of the body 3 that were damaged in a collision, for example. In one model, the control module 11 presents to the user, on the display or graphical user interface 100, respectively, a graphical representation of the car model and receives instructions from the user to select the part(s) of the body 3, p. . ex. pointing and clicking, touching or otherwise manipulating, depending on the type of user interface 10. Alternatively, the user selects the part(s) of the body 3 from a list or the control module 11 uses the processing of image to identify damaged body parts 3 from one or more photographs (digital images) of the damaged car or body parts 3 that are scanned or uploaded to the computer system 35 1.
    In step S3, the user of the computer system 1 defines, through the user interface 10, the damage of the part(s) of the body 3 defined in step S2. Specifically, the user defines, for one or more damaged areas 4a, 4b, 4c, 5a, 5b, 5c (4a-5c) of a body part 3, its location, shape and level of impact, the latter being indicative of the severity and/or depth of damage. In a model, different types of damage can be specified, e.g. ex. damage with a deformation of a body part or damage to the surface of a body part, eg. ex. scratches or other paint damage. Various steps taken to define the damaged areas 4a-5c of a body part 3 will be explained in detail below with reference to Figure 5.
    In step S4, based on one or more damaged areas 4a-5c in one or more parts of the body 3, the estimator module 12 determines the work items or operations, 10 respectively, recommended and/or necessary to repair the collision damage in the car, and creates an estimate of the cost and/or repair time for the user, as will be explained in more detail below with reference to Figure 6.
    In step S5, the operations generator 13 creates for the user repair procedures to carry out and complete the work items or operations identified in step S4 to repair the collision damage. Repair procedures include detailed instructions for carrying out work items or operations as a sequence of repair steps. In a privileged model, repair procedures are implemented as a set of one or more video sequences, which can be selectively viewed, stopped, reversed, advanced, skipped, and slowed down.
    In the following paragraphs described with reference to Figures 8a, 8b, 9a, 9b, 9c, 10a, 10b, 10c (8a-10c) we have an exemplary design of the graphical user interface 100 used to define collision damage on a defined body part 3. As illustrated in Figures 8a-10c, the graphical user interface 100 is implemented as a screen window with conventional window control icons 102 for closing the window and for minimizing, restoring, maximizing and adjusting the size of the window, for example. Depending on the model, the window still has function menus that are not illustrated and will not be described here. 105, an impact level setting area 104, an indicating instrument 107 and at least one drawing tool 108, 108'.
    Preview and Drawing Area 109 is configured to display a graphical representation or image of a selected body part 3. Preview and Drawing Area 109 is further configured to show on body part 3 a damaged area 4a-5c as drawn by the user through the drawing instrument 108, 108' or detected by the contour detector 15 from the image data of the selected body part 3 (or a damaged part thereof).
    Preferably, the graphical user interface 100 is configured to switch between the design instrument 108 and the indicating instrument 07. When the indicating instrument 107 is activated, the user's instructions control the position of the arrow 107' associated with the indicating instrument 107. When the drawing tool 107 is activated, the user's instructions control the position of the drawing tool icon 108' associated with the drawing tool 108.
    The drawing instrument 108, 108' allows the user to draw on the body part 3 an outline (or outline) of a damaged area 4a-5c on a selected body part 3 in the viewing and drawing area 109. The drawing instrument 108, 108' is configured to draw the outline of a damaged area 4a-5c through defined geometric shapes, e.g. ex. a circle, an ellipse or an oval, or - in the preferred model - as a manually defined point-to-point polygon or segment-by-segment, or a "freehand" closed line/curve, etc. The contour of a damaged area 4a-5c is positioned on the Body 3 part, defining with a drawing tool 108, 108' a starting point for the contour and/or moving the (finished) contour to a destination location on the part of body 3. Preferably, to draw a contour through a polygon or closed curve/line, the user uses the drawing tool 108, 108' to position individual corners or vertices of the polygon, or to navigate or move an icon associated with the drawing instrument 108, 108' to effectively draw the curve/line, respectively. In one model, the control module 11 uses graphics processing to adapt the outline of the damaged area 4a-5c to the 3D shape of the body part 3. Preferably, the damaged area 3 is saved as a graphic data object, e.g. ex. including a set of points and/or vectors defining its contour, shape, pattern, size and position relative to the respective body part 3. Note that damaged areas 4a-5c can also be defined and drawn as a simple line representing a scratch to the surface of the selected body part 3.
    The indicating instrument 107 allows the user to select objects in the viewing and drawing area 109, p. ex. a body part 3 or a damaged area 4a-5c, for further handling and processing. For example, a damaged area 4a-5c, which is defined and drawn by the user or the contour detector 15, can be changed with respect to its size, shape, location (position) and/or orientation, through the respective user instructions to resize, edit point or line, move and/or rotate the damaged area 4a-5c, respectively.
    The impact level setting area 104 is configured to receive instructions from the user to set the impact level of collision damage in a selected damage area 4a-5c. In the model shown in Figures 8a-10c, the impact level of a damaged area 4a-5c is defined using impact level selectors to select one of different impact levels. Specifically, impact level selectors are provided, such as mutually exclusive buttons or checkboxes, designated L, M, or H, to select a low, medium, or high impact level, for example. The selected ' impact level L, M, H is saved assigned to the respective damaged area 4a-5c.
    The size of a damaged area 4a-5c can be adjusted, eg. ex. using a slide bar designated S. In a model, if you use the slide bar S when a body part 3 is selected, this works as a zoom function and makes the body part 3 appear smaller or larger in the viewing and drawing area 109.
    In a model, setting the impact level for damage area 4a-5c causes the size and/or shape of a damage area 4a-5c to be adjusted.
    You can erase a damaged area 4a-5c, for example, using a erase button labeled D.
    The operations area 106 is configured to enumerate the work items or 15 operations required and/recommended to repair the defined car collision damage.
    In the model illustrated in Figures 8a-10c, the operations area 106 comprises a required operations section with necessary or highly recommended operations to repair collision damage, designated R, and proposed operations section with operations that are proposed at least for consideration. when repairing the collision damage, designated P. In these two sections of the area of operations 106, the necessary or recommended operations are enumerated, e.g. ex. each operation as a line item with a checkbox to select and deselect the operation, an operation identifier #1#,2 , #3, #4, #5, #6, and an operation name or description 01, 02, 03, 04, 05, 06.
    Estimate production area 105 is configured to display the estimated time and/or cost to repair collision damage to the car. In the model illustrated in Figures 8a-10c, the estimate production area 105 comprises two tabs, one for displaying estimated repair costs, designated as C, and one for displaying estimated repair time, designated as T. Both tabs C, T include a display part arranged on the tab and configured to show the total repair cost or time, respectively, regardless of which tab C, T was selected by the user. In the model in Figures 8a-10c, if tab C is selected, the detailed cost estimate is displayed, including the estimated cost of repair work CR, the estimated cost of materials and paint CM, and the estimated total repair costs TC . If the T tab is selected, the detailed time estimate is displayed, including the estimated time to perform the main operations TO, the estimated time to perform additional operations TA, the estimated time to paint TP, and the estimated total repair time TT. Figures 8a, 9a, 9c, 10b illustrate the graphical user interface 100 in the state where tab T is selected and tab C is disabled; while Figures 8b, 9b, 10a, and 10c illustrate the graphical user interface 100 in the state where tab C is selected and tab T is disabled.
    Depending on the type of user interface 10, the indicating instrument 107 or its associated arrow 107', respectively; the design tool 108 or the icon associated with the design tool 108', respectively; the L, M, H impact level selectors; the slide bar S; the delete button D; separators C and T; 10 and/or other generating elements of the graphical user interface 100, such as the scroll bar 103 or the "CANCELT or "OK" button, are operated by the user via an indicating device controlling an indicator or by touching the operating elements on the screen, directly with your fingers or with a stylus, depending on the type of user interface 10, display and/or input elements 101, respectively.
    As illustrated in Figure 5, to define collision damage on a defined body part 3, in optional step S31, the user selects in the graphical user interface 100 the drawing tool 108, if it has not already been selected or activated. Figures 8a, 9a, 9c, 10b illustrate the graphical user interface 100 in the state and that the indicating instrument 107 is selected and the drawing instrument 108 is disabled, 20 thus showing in the viewing and drawing area 109 the arrow 107' as the active user controllable indicating device; while Figures 8b, 9b, 10a, and 10c10b illustrate the graphical user interface 100 in the state where the drawing instrument 108 is selected and the indicating instrument 107 is disabled, thus showing in the display and drawing area 109 the icon associated with the 108' drawing instrument as the active user controllable painting device. Figures 8a and 8b illustrate the graphical user interface 100 in a state where the body part 3 is presented without any damaged areas drawn thereon.
    In step S32, the user uses the drawing tool 108 or the icon associated with the drawing tool 108', respectively, to draw a damaged area 4a-5c 30 on the body part shown 3. Alternatively, a photograph or an image of the selected body part 3 and/or the damaged area 4a-5c is scanned and/or uploaded by the user to the computer system 1, and the outline of the damaged area 4a-5c is detected by the contour detector 15 from the image data . As shown in Figures 9a-10c, the contour of the damaged areas 4a-5c is transferred and drawn on the body part 353 as instructed by the user via the drawing instrument 108, 108' or as created by the contour detector 15, respectively. As mentioned above, the size of a selected damaged area 4a-5c can be changed and, depending on the type of drawing instrument 108 used, the shape of the damaged area 4a-5c can also be changed.
    In step S33, the user sets the impact level of a selected damaged area 4a-5c. In Figure 9a, the damaged area 4a is shown with a low impact level 5; in Figure 9b, the damaged area 4b is shown with a medium impact level, and in Figures 9c, 10a, 10b and 10c, the damaged area 4c is shown with a high impact level. In Figure 10a, the damaged area 5a is shown with a low impact level; in Figure 10b, the damaged area 5b is shown with a medium impact level, and in Figure 10c, the damaged area 410c is shown with a high impact level.
    Although this is not visible in the black and white Figures, the graphical user interface 100 is configured so that the damaged areas 4a-5c are filled and/or outlined with a color that depends on the impact level assigned to the damaged area. 4a-5c and corresponds to the color of the respective impact level selector L, M, H.
    Once the user has completed the collision damage definition on selected body part 3, or if the user wants to get an intermediate estimate for the damage defined so far, step S3 is completed by clicking the "OK. Subsequently, the" control module 11 activates estimator module 12 to perform an updated repair estimate including damaged areas 4a-5c drawn on body part 3.
    In step S4, the estimator module 12 determines an estimate of the time and/or costs required to repair the defined collision damage.
    In step S41, the estimator module 12 returns the characteristics of the selected body part 3 from the database 14.
    In step S42, the estimator module 12 determines other parts of the car that are or may have been impacted and damaged by the collision. These other car parts are determined by the estimator module 12 based on the characteristics of the selected body part 3, and the shape, location and impact level of the damaged area 4a-5c. Specifically, the estimator module 12 uses information about the body part's relative position and distance to other car parts, or vice versa, in combination with the shape, location and impact level of the damaged area 4a-5c, to identify other parts of the car that are or may be damaged by the collision. To determine the probability of another car part being damaged by the collision, the estimator module 12 relies on memorized data and/or defined algorithms, taking into account statistical data from a series of collision damage reports. For example, if a car part is located in the vicinity of the damaged area 4a-5c, p. ex. if one perpendicular to the body part 3 is in the damaged area 4a-5c and passes through the respective other car part, the probability that the respective other car part has been damaged is calculated as a function of the relative distance of the other car part, the material and thickness of the body part and the level of impact in the damaged area 4a-5c. Essentially, the material and thickness of the body part 3 and the impact level define a temporary (dynamic) and/or permanent deformation of the body part 3 in the damaged area 4a-5c as a result of the collision. The probability of damage depends on the temporary and/or permanent deformation (damage) of the body part 3 and the relative distance from a respective other car part to the body part.
    In step S43, the estimator module 12 determines work items or operations to repair the collision damage. Work items or operations are determined by the estimator module 12 based on the characteristics of the selected body part 3 and 10 damage probabilities of other car parts. For example, the estimator module 12 shows, in the necessary operations section R of the operations area 106, those work items or operations necessary to replace and/or repair the damaged areas 4a 5c and other car parts with a given calculation probability. damage at or above a defined upper damage limit level. Correspondingly, work items 15 or operations necessary to replace and/or repair other car parts, with a given damage calculation probability below the defined upper damage limit level, but above a lower damage limit level, are presented by the estimator module 12 in the proposed operations section P of the operations area 106. Subsequently, the estimator module 12 receives instructions from the user of the work items or operations in the operations sections R, P required and proposals of the operations area. 106 that have to be included in the estimated cost and/or time. For example, as illustrated in Figures 9a-10c, work items or operations are selected by the user by setting ticks in the respective checkboxes.
    In step S44, estimator module 12 determines the estimated time required to repair and/or replace body part 3. Estimated repair time is determined by estimator module 12 based on the characteristics of selected body part 3, and the shape , location and impact level of the damaged areas 4a-5c. Specifically, the estimator module 12 uses information about the material, thickness and repair accessibility of the body part in combination with the shape, location and impact level 30 of the damaged areas 4a-5c, to determine the estimated repair time. To determine the repair time, the estimator module 12 relies on memorized data and/or defined algorithms, taking into account statistical data from a series of damage repair reports. The estimated replacement time is determined by the estimator module 12 based on the replacement time information stored in the database 35 14. In a model, the decision whether to repair or replace a body part 3 is made by the estimator module 12 based on in cost and/or time efficiency as described below.
    In step S45, estimator module 12 determines the estimated costs to repair and/or replace body part 3. Estimated repair costs are determined by estimator module 12 based on estimated repair times and hour prices stored on the basis of data 14. In addition, estimated repair costs include estimated costs for materials needed for repair. To determine the estimated costs for materials needed for repair, the estimator module 12 relies on memorized data and/or defined algorithms, taking into account statistical data from a series of damage repair reports. Estimated replacement costs are determined by estimator module 12 based on time and price information 10 stored in database 14 for body part replacement.
    In step S46, the estimator module 12 determines the estimated time needed to replace other car parts. The estimated repair (replacement) time is determined by the estimator module 12 based on the replacement time information stored in the database 14.
    In step S47, the estimator module 12 determines the estimated costs to replace other car parts. The estimated repair (replacement) costs are determined by the estimator module 12 based on the time and price information stored in the database 14 for replacement of the respective car part.
    At step S48, the estimator module 12 determines the estimated time required to 20 paint the repaired or replaced body part 3. The estimated time for the paint job is determined by the estimator module 12 based on the time and/or size information stored in database 14 for the body part 3.
    In step S49, the estimator module 12 determines the estimated costs to paint the body part 3. The estimated costs to paint the body part 3 are determined by the estimator module 12 based on the time and price information stored in the database. 14 for painting the body part 3.
    Figure 7 shows a flowchart illustrating an exemplary sequence of steps to define one or more damaged areas 4a-5c in one or more parts of a car's body 3 and create an estimate of the car's collision damage, including time and 30 estimated repair costs.
    In step S1, the car model is selected as described above with reference to Figure 4.
    In step S2, a damaged body part 3 is selected and displayed on the graphical user interface 100, as described above with reference to Figure 4.
    In step S301, a damaged area is drawn on selected body part 3, as described above in the context of step S32 with reference to Figure 5. For example, the outline of damaged area 4a is drawn on body part 3 as illustrated in Figure 9th
    In step S302 the impact level for the damaged area 4a is set, as described above in the context of step S33 with reference to Figure 5. For example, the impact level for the damaged area 4a is set to lower the impact L as illustrated in 5 Figure 9a.
    In step S401, an estimate for the damaged area 4a defined far is created, as described above in the context of step 54 (including steps 541-549) with reference to Figure 4. Correspondingly, as illustrated in Figure 9a, for example, the work items or required operations #1-01, #2-02 are displayed and verified 10 in the required operations section R of operations area 106. In addition, the estimated total time required to perform the checked operations and thus repair the damaged area 4a is determined and displayed in the time tab T. As the tab T is selected as the active tab, the estimate production area 105 also shows details of the time estimate, including the estimated times to perform the operations 15 main TO, to perform additional TA operations and to paint the TP body part. In addition, the estimated total costs to repair damaged area 4a are determined and displayed in cost tab C.
    At step S402, the control module 11 checks whether the damage to selected body part 3 has been completely defined or whether more damaged areas 20 should be drawn on selected body part 3. For example, to complete the definition of damage to a selected body part. body, the user can select another body part or finish setting the car's collision damage. If it is to draw other damaged areas 4b5c on selected body part 3 or if it is to change a damaged area 4a-5c or change its impact level, processing continues in step S301; otherwise, processing 25 continues at step S403.
    Figures 9b-10c show the graphical user interface 100 in correspondence with different repetitions of the sequence of steps S301, S302, and S401.
    Specifically, Figure 9b shows the graphical user interface 100 after the impact level of the damaged area 4b has been set to medium M. Correspondingly, in the required operations section R of the operations area 106, the work items or operations required are increased in another #2-02, taking into account the increased impact level and size of the damaged area 4b. In addition, the estimated time required to carry out the verified operations and thus repair the damaged area 4a is (re)determined and displayed in the time tab T. Additionally, 35 the total estimated costs to repair the damaged area 4a are (re)determined and displayed in the cost tab C. As tab C is selected as the active tab, the production estimate area 105 also displays the cost estimate details, including the estimated cost of repair work CR, the estimated cost of materials and paint CM, and the estimated total repair costs TC.
    Figure 9c shows the graphical user interface 100 after the impact level of the damaged area 4c has been set to high H. Correspondingly, the required work items or operations are increased by another item #3-03. In addition, the estimates for repair time and costs are recalculated, taking into account the changed size and impact level of the damaged area 4c, and the production area of estimates 105 is updated accordingly.
    Figure 10a shows the graphical user interface 100 after an additional damaged area 10 5a has been drawn on selected body part 3, its impact level set to low L. Correspondingly, the proposed work items or operations are increased by another item #5-05. In addition, the estimates for repair time and costs are recalculated, taking into account the addition of the damaged area 5a, and the production area of estimates 105 is updated accordingly.
    Figure 10b shows the graphical user interface 100 after the damage area impact level 5b has been set to mean M. Correspondingly, the required work items or operations are increased by another item W 4. In addition, the estimates for repair time and costs are recalculated, taking into account the changed size and impact level of the damaged area 5b, and the production area of the 20 estimates 105 is updated accordingly.
    Figure 10c shows the graphical user interface 100 after the impact level of the damaged area 5c has been set to high H. Correspondingly, the proposed work items or operations are increased by another item #6-06. In addition, the estimates for repair time and costs are recalculated, taking into account the changed size and impact level of the damaged area 5c, and the production area of the estimates 105 is updated accordingly.
    In step S403, an estimate is created for the body part 3, including the damaged areas 4c, 5c drawn on the body part 3 at their current impact levels, as described above in the context of step S4 or step S401, respectively. If in step 30 S402 the estimate is not only created for that damaged area 4a-5c that is being defined, but is updated for all damaged areas 4c, 5c drawn on body part 3 at their respective impact levels, step S403 is not required and therefore optional.
    In step S404, the control module 11 checks whether damage has been set for all 35 parts of body 3 that have been impacted by the collision or whether there are other parts of body 3 that have to be selected S and have damaged areas 4a-drawn on them. 5c. If it is to select other parts of body 3 for the damage definition or if it is to change a damaged area 4a-5c or change its impact level on another part of body 3, processing continues at step 52; otherwise, processing continues at step S405.
    In step S405, an estimate is created for the car's total collision damage, including the damaged areas 4c, 5c drawn on all body parts 3 at their current 5 impact levels, as described above in the context of steps S4, S401 or S403, respectively. If in step S401 or S403 the estimate is not only created for that damaged area 4a-5c or that body part 3, respectively, that is being defined, but is updated for all damaged areas 4c, 5c drawn on all parts of body 3 at their respective impact levels, step S405 is not necessary and therefore optional.
    At step S5, the operations generator 13 creates for the user detailed repair procedures to carry out and complete the identified work items or operations (as described above in the context of step S43), at steps S401, S403 or S405, respectively. , to repair the collision damage. Repair procedures 15 are shown, for example, in the display or drawing area 109 of the graphical user interface 100, and may be printed on paper or stored on a computer readable data storage medium.
