    [0001] The invention relates to an instrument for taking pictures and measurements of the parameters of a person's face for producing eyeglass frames (spectacle frames made to measure). or make a selection of frames based on the data collected by the instrument. In this second case we will have the best match between the peculiarities of the face, its specificities, its parameters and the technical data sheets of spectacle frames. From this observation arises the idea of designing a measuring instrument that takes the nasal print and other parameters of the individual's face for the purpose of making eyeglass frames on a scale. Our measuring instrument and 3D views would have the role of leading our client to glasses frames selected according to the morphology of the individual. From the parameters collected by the tool, that we can manufacture a frame of cellulose acetate (plastic frame) or other natural materials wood, shell, bamboo, horn etc .... And get precisely the different information namely the hunting angle, the angles of faces, as well as the angle of the nasal ridge (crest angle) and all other parameters of the face, in order to achieve, after processing information by through a computer, an eyeglass frame perfectly adapted to the client's morphology. The frame of the frame will be optimal and will correspond to the specificities and peculiarities of the physical features of the individual. 3038078 2 This is the frame that adapts to the morphology of the face, and not the opposite, or thanks to the elements provided by our device of measurements and views, our tool will allow us to select the best frames of glasses in a shop. 5 Our measurement and vision tool will allow us to determine a "morphological assessment of the face". Depending on the parameters obtained by the instrument, it will be possible to have a fine selection of eyeglass frames in relation to the measurements of the individual's face, the shape, the size and the positioning of the tenon which determines the inclination of the branches will be obtained. as well as the length, then we will be able to refine the selection with respect to the desired type of eyeglass frames (metal rim, plastic rim, breakthrough, nylon), and the second selection parameter the color of the desired eyeglass frame. Our goal is to offer the best spectacle frames to the customer. We can do the fitting in a virtual or real way, in the case of virtual fitting our tool will also allow us to model the face of the customer as well as the modeling of spectacle frames. We can obtain the superposition of the 2 levels of modeling and have the face + the selected mount. The goal is to get a selection of extremely precise eyeglass frames. Then the optician positions ophthalmic lenses, according to a medical prescription, which will therefore generate visual comfort and stability of the optical equipment.
    [0002] It is rare to meet symmetrical faces, so that one could make asymmetry a rule almost general. Most of the time, these morphological asymmetries can have consequences, either on the respiratory tracts (nasal deviations) or on the vision (ocular asymmetries). The observation of asymmetry is important in three aspects: the aesthetics, the comfort of the frame, and the visual balance.
    [0003] Cellulose acetate, more specifically cellulose acetate ester in the form of fibers, is a plastic material, also known as rayon, artificial silk, viscose, etc. Cellulose acetate is used to make eyeglass frames, and especially to make eyeglass frames without nose pads or fins for supporting the eyeglass frame on the nose. We find the same problems for wooden eyeglass frames, horn eyeglass frames, eyeglass frame frames and finally all frames of 10 glasses in natural material. The nasal fins provided on certain spectacle frames are generally designed so as to be adapted to the nasal morphology of the individual wearing the frame and more broadly to all the parameters of the face which will necessarily have an effect on the choice. glasses frames. The nose pads are therefore movable relative to the frame and can therefore move away from each other or approach (this is the case of metal spectacle frames which have platelet arms where one can therefore intervene in the context of an adjustment).
    [0004] In a spectacle frame, such as a frame made of cellulose acetate, wood, horn, etc., without nasal fins, it is not possible to adapt the nose reception area to the morphology of the nose. 'an individual. These glasses can only be worn by a certain number of individuals whose nasal morphology 25 adapts to the shape of the nasal housing provided on the frame. Details of the face: From the angle of eyewear, the nose is a pyramidal support, three faces, two of which are in close contact with the mount. The object of our invention is to obtain a mount 30 perfectly adapted by marrying all the features of the nasal superstructure and thus by providing various internal organs hidden therein. Since the nose is a 3038078 4 three-dimensional volume we will examine it from the front, from the side, from above and from below. a) Nose seen from the front The width that interests us in the field of eyewear, 5 is not so much the actual width of the nose at its root, but that measured in the plane of the frame about 12 mm from the top of the eye. cornea. The appreciation of this width is quite easy in the case of a nose well shaped, salient and very regular. It is more difficult for undeveloped noses such as those of young children and very flat noses. Depending on the port of the telescope that the client wishes it will have a consequence on the parameter of the nasal width. Some customers wear their glasses very high others very low. Depending on this choice, there will be an impact on the different angles of the frame (the front angle, the hunting angle, etc.). In principle the root of the nose is the narrowest part. But there are exceptions Figure 2. This kind of nose often poses adjustment difficulties. The conventional shapes of the present mounts 20 are not provided for these particular shapes (see Fig. 2 (b), which is why we are going to develop the tool to provide a solution.) B) Angle of face This are the right and left angles formed by a vertical line and an imaginary line tangent to each side of the nose and the "nasal side slope". Starting from the root "N", we measure another width "N", hence the importance of asking where the customer is wearing these glasses (see Fig. 3). And we will put a mark on the nose before launching measurements and views with our tool. For those who are used to wearing glasses often there are marks left by the old mounts, there is in this case, to put the new frames in the same traces as the previous 3038078 5. Other times, it will be necessary to avoid a furrow made sensitive by the old glasses. c) Nose profile At its root relative to the brow bone and the ascending apophysis of the upper maxilla, the root of the nose can be hollow, basement, parallel or protruding. The classic projection is the distance from the top of the cornea to the root of the nose. This rib is positive, zero, or negative, depending on whether the root is forward, above, or behind the axis tangent to both corneas. But the optician must judge the projection of the bridge of the future mount according to the vertical plane (or slightly inclined forward) located 12 mm in front of the cornea fig4. This will determine the concept of salient, not the nose itself but the bridge of the pair of glasses that will be negative, positive or zero. The same will be true of the height of the bridge which will be taken at the level of the visual axis at the point of intersection with the plane of the glasses (Fig. 4). d) The nose seen from above We have the hunting angle in view from above, this angle can be very great for some breed (50 ° and more), see fig. 5, large for most of some breed 30 ° to 50 ° means of 10 ° to 30 ° Small of 0 ° to 10 ° No 0 ° in other breed. Width, height, protrusion of the root, angle of the face, angle of flush, nasal slope seen in profile will be perfectly measured using our measuring instrument. The nose is therefore one of the elements of the face whose shape can vary enormously from one individual to another. Indeed, the base of the nose may be more or less wide and more or less protruding from the face with significant variations.
    [0005] Beyond the parameters of the nose, the tool also allows us to obtain information concerning the eyebrows, the cheekbones, the temples as well as the distance of the glasses to the ears (dimensions of the branches). We still want to change this visualization by making it more attractive and real, especially in its application among 5 opticians to allow customers to have a unique frame perfectly adapted to its morphology. The object of the invention is therefore to provide a device that meets these requirements for three-dimensional visualization of the individual's face.
    [0006] Historical reminder of the measurements: Before: We had (and we still have) the ruler, originally used in this form with a scale in millimeters or half millimeters, although this last graduation makes it less clear that that it increases accuracy. All these rules that allow an assessment of pupillary differences have a common drawback. They are intended to be placed above the eyes of the subject. For this reason they make awkward shade on the pupils, especially in the case of dark Iris. In addition their irregular cutting gives different shadows on each eye, which makes the measurement painful and inaccurate. Another slider: that of SASIENI It is an almost universal instrument composed of two parts a) the first element is used to measure the pupillary distance, the nasal width, the temporal gap of the length and the inclination branches. (b) the second element is used for all things concerning the nose: ridge angle, radius of curvature of the root, width of the nose, angle of the face, nose protrusion.
    [0007] Cephalometers These instruments are suitable for measuring the width of the head at different points. The optician used it frequently to determine the opening of the branches of the spectacles and the minimum width of the face of the frame. They are of two types: sliding or compass. Their handling is rather difficult and the pressure exerted on the head difficult to control which makes its precision rather illusory when the head is round, with curved temples, it is necessary to take the superior ear gap behind (which does not is hardly practical). These tools allow us to measure sphenoidal, upper atrial, and temporal differences. Nose measurement: Numerous devices have been invented to evaluate the various nasal dimensions. One uses some rules with articulation (ornic, Sasieni etc ...). The test glasses is a good instrument for measuring the height and prominence of the nose according to the plane of the glasses. Rhinometers: it consists of 2 identical strips held by 2 screws. The 2 parts slide against each other thanks to 2 slots in which the 2 screws can slide in such a way that one can adapt the instrument to the various widths of nose. This instrument allows me to measure the front angles and the hunting angles.
    [0008] 20 Measuring branches The length and inclination. The origin of the measurement on the branch itself is the axis of articulation. We count either the total length or the distance of the axis at the birth of the curve. For this we have the 25 ruler, test glasses, branches of varying lengths, articulated rulers of the type Reinhardt ornic etc ... The inclination of the branch is the angle that the open branch with a normal in the back plane of the face (side view). This inclination depends on the morphology of the face. The trial glasses 30 whose branches are variable inclination can be used to calculate this inclination.
    [0009] 3038078 8 All these tools have in common the lack of stability since we have to hold them by hand on the face of the subject. Today: We want to synthesize all these instruments into one. We believe in the design of a measuring instrument that can bring together all of the devices studied previously. This is the object of our invention. This kind of tool will undoubtedly be the most accurate instrument that can be imagined for all these measurements to be obtained at the same time, in a single step, in a single computer click. Eyewear opticians can find in this serious instrument a real efficiency, and that can enhance the standing of their profession. Eyeglass frames are therefore designed and manufactured from a medium nose shape, the average nose shape may vary depending on the frame as well as other average facial parameters. Therefore, not all eyeglass frames can currently be worn by all individuals. The object of the invention is to overcome these drawbacks by providing an apparatus for taking pictures and measurements, in particular of the nasal impression, and other facial parameters, the sphenoidal, upper atrial, temporal, etc. reproduce the face in three dimensions on a screen and get digitized information of the shape of the individual's face.
    [0010] To obtain precise measurements of the face, we will position adhesive micro data sensors on the skin of the face. The locations of these microsensors will be very precise and will allow to obtain in one step all the desired and indispensable information (see Fig. 13). The data sensors 15 are 15 in front view, 5 on the left profile (see left side view (Fig. 13)), and 5 on the right profile (right side view). Each sensor will be named from c15 to c15.
    [0011] 3038078 9 This in order to: - manufacture a frame made of cellulose acetate (or in certain natural materials) perfectly adapted to the morphology of an individual. The optimization of the shape of the frame is achieved by the nasal impression recorded by the instrument; or - to choose the best eyeglass frames from a store, or from several stores according to the information recorded by our measuring instrument. According to one aspect of the invention, there is provided a device for digitally taking pictures of a face of an individual comprising a box, means for illuminating the face, means for digitally shooting the face and transmission means capable of transmitting the information relating to the shots to processing means.
    [0012] According to a general characteristic of the invention, the camera is able to move the camera means. The individual sits in an armchair, the whole being positioned on a motorized turntable. The rotation is done in a 360 ° arc. The complete lap will be done slowly on the order of 1 minute for a complete lap with 4 times of pause of the order of 10 seconds for each stop, we can vary this parameter of the pause time more or less long. These breaks are therefore variable. The stops are set at 0 °, 90 °, 180 °, 270 °, and return to the initial 360 ° position. At 0 ° the means of shooting and 25 measurements will be able to obtain a view of the face in right profile, at 90 ° one will obtain a front view of the face, at 180 ° one will have a left profile view of the face and finally to 270 ° we will have a rear view. At each pause and at the end of the pause time of 10 seconds the scanner snaps and gets a shot. The face of the individual is positioned on a chin support, which itself is fixed on a horizontal metal rod (TH1), which itself is fixed on a vertical metal rod (TV1) see FIG. 13a, this vertical rod 3038078 10 is welded to the chair, so that the chin support can rotate around the axis A4 in the horizontal plane. To change from position 3 to position 4 see fig.
    [0013] 12 Bis. In position 3 the individual can sit in the chair which would not be the case if the chin support was in position 4. Once the individual is seated in the chair is made to rotate the chin support for arrive at position 4 so that the chin support is in front of the face of the individual. The device comprises means for adjusting the chin support able to move the chin support vertically and horizontally. These adjustment means make it possible to correctly adjust and center the face of the individual with respect to the means of shooting and measuring. . At the level of the chin support, the number of targets was set at 3, one on the left and one on the right, so that at each pause the scanner could focus on the sights. The individual will perform a rotation of 360 ° with 4 sequences of exposure time of 10 seconds, it will be equipped with a collar at the neck. This necklace has a pattern that corresponds to the 4th pattern in the 270 ° plane. 12 c. At the chin support, therefore, we have 4 patterns, so that the scanner or camera will focus at each end of the break times. These patterns are located in each plane namely 0 °, 90 °, 180 °, 270 ° the first cycle will have made a complete rotation of 360 °. The face is immobile it is located in the curved housing of the chin support. This avoids any movement of the face, this parameter is very important for a rendering of the high quality image. The patterns are references, they are very important, because they will allow us to have benchmarks and from these points of reference obtain the desired measurements. The support is bonded to two metal rods, one vertical and the other horizontal. The horizontal rod is fixed on the armrest of the chair. For more ease our chair has only one armrest. The armchair is attached to the turntable, by 3 3038078 11 threaded rods, it is all that is dynamic and makes a rotation of 360 ° (armchair, armrest, vertical and horizontal rods, support chin, individual). The complete rotation is done in 1 minute, this parameter will be adjustable more or less long. In the case where the person is disabled and is in a wheelchair, we will have the possibility to remove the basic chair through the 3 threaded rods see Fig.
    [0014] 12 Bis. When the wheelchair is in the center of the turntable, we will have a second chin support whose vertical metal rod is larger, whose attachment is directly in the turntable, in a notch (EN) see FIG. 13 ter. This chin support is also fixed on two metal rods, one vertical, and the other horizontal, to refine the centering settings, so that the face 15 is perfectly centered with respect to the means of shooting and measurement. The chin support is adjustable in height along the Y axis and thus along the X axis (see Fig. No. 12 b) Here again the chin support will rotate 180 ° to move from position 3 to position 4 .
    [0015] It will also be necessary to develop a ramp so that the wheelchair can access the turntable since there is a difference in height between the ground and the turntable. Regarding the targets, three are on the chin support, and the fourth is on a collar. The No. 1 target which is front and has a particularity, it can tilt at 45 °. So that during the second cycle of shooting and measuring, the axis A3 of the scanner or the camera in position 2 (see Fig. 12) is parallel to or coincident with the axis of the target A5. It is in these conditions that the focus is optimal. These shots and measurements are all very important. It is from this basis that we can develop the real bespoke and thus obtain reliable and accurate measurements.
    [0016] 3038078 12 Adhesive data sensors are positioned on the skin, these points are precise and correspond to reference elements. Such a device makes it possible to provide a three-dimensional image of the entire face of the individual in order to visualize it on a screen 5 in space and to be able to move it in rotation, giving a particularly real rendering of the face to an observer. The shots are dynamic and continuous which provides a particularly real screen rendering. The imaging means may advantageously be a camera or a scanner. Preferably, the device further comprises adjustment means with respect to a horizontal axis for positioning the customer's face in the axis of the device of the position-taking means 1 (see Fig. 7).
    [0017] The adjustment means thus make it possible to correctly center the face with respect to the means of shooting before starting the shots. The displacement means can advantageously be configured so as initially to move the imaging means in a first vertical plane by a translation (Z) (see FIG. 8), and in a second step to rotate the element ( 5) means of shooting, which will determine the axis (A3) (see Fig. 8). This movement of the camera and measurement device takes place between the position (1) (see Fig. 7) and the position (2) (see Fig. 8) which defines the named translation (Z); this displacement is done only in the vertical plane. Following this rectilinear movement, the element (5) (scanner or camera) will rotate on the order of 45 ° (see Fig. 8). In position (1) the device is fixed, it is the seated individual who rotates from 0 ° to 360 ° thanks to the rotated turntable (TM). This movement takes place around the A2 axis.
    [0018] 3038078 13 Then in position (2), after the translation of the device and the rotation of the element (5), the assembly is fixed. It is again the seated individual who rotates in a 0 ° to 360 ° arc through the motorized turntable (TM) (see Fig. 8). This movement is around the A2 axis. These 2 shots provide a three-dimensional representation of the face. These plans are complementary. These Al and A3 axes are indispensable for characterizing a 3-dimensional image. These are the conditions sine qua non to obtain the volume of the customer's face. Therefore, these two work plans are mandatory. Advantageously, the displacement means may comprise a guide rail for moving the viewing means in a vertical plane and a second guide member to allow the member (5) to rotate. The device may further comprise electronic control means capable of controlling the movement means. Advantageously, the lighting means may comprise a plurality of fluorescent tubes arranged in the box to generate homogeneous and shadow-free illumination. This gives a structured light. According to another aspect of the invention, there is also provided an apparatus for digitizing the shape of a face of an individual comprising a shooting device as defined above, means for processing the shots of views able to measure facial parameters from digital shots and to reconstruct a three-dimensional digital image of the face of the individual.
    [0019] Preferably, the apparatus further comprises a display screen adapted to display the three-dimensional image of the individual's face.
    [0020] The three-dimensional representation of the face can thus be visualized on the screen and it is then possible to add to the screen eyeglass frames adjusted to the morphology of the client to realize the final rendering before the manufacture of the frames.
    [0021] 5 Frame settings such as color, shape, etc. can be adjusted on the screen. Adhesive data sensors are positioned on the individual's face, and they transmit their measurements by means of treatment to digitize the face.
    [0022] The client's eye height is adjusted with respect to the camera's means of shooting, at least sequential or continuous shots are captured at a circle arc of 36 ° in the horizontal plane, the device being fixed and the individual is in rotation which corresponds to a first cycle (position (1)). Then in position (2) 15 the device is fixed and it is again the individual who makes a rotation of 360 ° around the axis A2, then we treat all the information taken by the means taken views to reconstruct a three-dimensional image of the individual's face and visualize the three-dimensional image on a screen. Figure 1 schematically shows a portion of a face seen from the front; - Figure 2 shows two different examples of nose shape; - Figure 3 shows three different examples of front angles; Figure 4 shows three examples of nose shape seen from profile; - Figure 5 shows a top view of a nose; - Figure 6 shows five examples of hunting angles; FIGS. 7 and 8 are diagrammatic views of a picture taking device according to an embodiment of the invention respectively in position (1) and position (2) operation; Fig. 9 is a perspective view of the outside of the camera; FIG. 10 schematically illustrates a view from above of the inside of the device; Figure 11 schematically shows a front view of the interior of the device; - Figure 12 shows a side view showing the moving means in the vertical plane of the shooting means; FIG. 13 shows the location of the adhesive pickup microphones. - Figure 14 obtaining measurements of facial parameters. - Figure 15 superposition of the face in 3D and measurements of the face. - Figure 16 seen from above the face taking into account the curve of the front. - Figure 17 shows a spectacle frame according to the parameters of the individual. - Figure 18 shows an example of on-screen display of the device of the individual + of the spectacle frame.
    [0023] In eyewear, the nose is a pyramidal support with three faces, two of which are in contact with the frame. The object of the invention is therefore to obtain a frame perfectly adapted to the nasal morphology of the individual by matching all the features of the nasal structure and other facial parameters. In Figure 1 is illustrated a face portion viewed from the front. Front, the nose has a width that varies from its root located roughly between the two eyes at its top bearing the two nasal orifices. In eyewear, the value taken into account for the width of the nose is the width measured in the plane of the eyeglass frame. This width is measured in a plane relatively parallel to the face of the face and cutting the nose at a distance of 12 mm from the top of the cornea of the eyes. The appreciation of this width is quite easy in the case of a 3038078 16 protruding nose and regular shape. It is more difficult on the other hand for less developed nose, especially less prominent, as in young children, or very flat noses. Depending on the height at which the individual wears his glasses on his nose, not only the nasal width of the frame varies, but also the angles of the mount such as the angle of face a and the angle of flush O On each side of the nose, a face angle α, visible in Figure (1), is the angle formed between the direction extending between the root of the nose and the top of the nose and the vertical direction. As illustrated in FIG. 10, in a front view of the face of the individual, if a first straight line passing through the eyes of the individual is taken, a face angle a is the angle formed by a straight line perpendicular to the first straight line at the cutting point of the nose with the first straight line and the straight line passing through this cutting point and tangential to the outside of the root of the nose. The front angles a are the right and left angles of the nose formed by a vertical line and an imaginary line tangent to each side of the nose and the nasal side slope. In principle, the root of the nose is the narrowest part of the nose as illustrated on the face portion shown on part (a) of Figure 2.
    [0024] But there are exceptions with configurations as shown in part (b) of Figure (2). The type of nose illustrated in part (b) of Figure 2 poses difficulties in adjusting the glasses, the conventional shapes of the current frames are not provided for these particular shapes. Figure 3 shows three examples of front angles for three different nose morphologies, symmetrical or asymmetrical. To measure the angles of face on a face, one measures a first width n at the level where the individual usually wears his glasses, and one marks the place of measurement. Then, from this mark, we descend from a fixed height, for example 27 mm, and we measure another nose width by distinguishing the right contribution 3038078 17 of the left contribution in the case where the nose is not symmetrical . The angles of face are then determined from both nose widths and height. Figure 4 shows three examples of nose shape seen in profile. As illustrated in the examples of FIG. 4, with respect to the brow bone and the ascending apophysis of the upper maxillary, the root of the nose may be hollow, basement, parallel, or prominent. The classic projection is the distance from the top of the cornea to the root of the nose. This dimension is positive, zero or negative, depending on whether the root is forward, on or behind the axis tangent to the two corneas as respectively shown in the three examples of FIG. (4). An optician judges the projection of the bridge of the future mount according to the vertical plane, or slightly inclined forwards, located 12 mm in front of the cornea.
    [0025] In Figure (5) there is shown a top view of a nose. Viewed from above, the nose has a hunting angle O. The hunting angle is the angle formed between the horizontal plane and the nose when looking at the nose from above. The hunting angles define the wheelbase of the nose.
    [0026] According to the morphologies, the flushing angle θ may be greater than or equal to 50 °, between 30 ° and 50 °, including being 10 ° and 30 °, or even less than 10 ° and even zero in some individuals as is illustrated on the five examples of flush angle of Figure 6. On mounts with adjustable nose fins, the flush angle 25 of the frame can be adapted after design of the frame. But on frames cellulose acetate and natural materials do not have nasal fins, no adaptation is possible after the manufacture of the frame. In order to adapt the eyeglass frames to the face shape of the invention, in one embodiment there is provided an apparatus for digitizing the shape of a face of an individual comprising a camera, means for 3038078 18 shot processing system able to measure facial parameters from digital shots and to reconstruct a three-dimensional digital image of the face of the individual and a display screen capable of displaying the image in three dimensions of the face of the individual.
    [0027] In Figure (7) there is shown a device for digitally taking a face of an individual according to an embodiment of the invention. The device comprises a box 1, for example parallelepipedic. In the box (1) are mounted a lighting (2).
    [0028] The illumination (2) comprises a plurality of fluorescent lamps arranged in the box (1) so as to create a homogeneous structured light and not generating shadows on the face. Sensors are releasably disposed on the face. As illustrated in Fig. (11), the illumination (2) comprises four neon lights L1, L2, L3, L4 which are advantageously positioned to create the structured light. The illumination could alternatively comprise fluorescent tubes calibrated at 6500 K. The device further comprises, arranged in the box (1), means (5) for taking pictures (5) such as a camera or a scanner, means transmitting (8) the information collected to a processing unit. The shooting means (5) are fixed in position (1) (see Fig. 7). The use of the device is carried out as follows: the box (1) is centered relative to the face of the individual along the Al axis by means of the rail B illustrated in Figures (7) and (8). When the centering is correct, the camera and measurement device becomes stationary while the rotation of the individual seated on a motorized turntable takes place. In position (1) the adjustments are made so as to center the face of the patient with respect to the camera means (5) placed in an initial neutral position.
    [0029] 3038078 19 Once the head of the individual in position relative to the box, the lighting (2) is lit. The shooting means (5) then begin a series of shots, or continuous shooting, first in the horizontal plane, the individual describing a circular arc of 5 360 ° along the axis A2. The person sits in a chair, which itself is positioned on a motorized turntable, the rotation is around the axis A2. This tray can support loads of 15Kg up to 200Kg. This motorized turntable can be controlled by the computer. The cycle is complete when the individual has made a rotation on itself from 0 ° to 360 °. The first shooting cycle is obtained at this stage (see Fig. 7). Then the second shot cycle is obtained by the movement of the camera in a vertical translation of the order of 50 cm in the vertical plane (Z) see Fig8. Then we rotate the order of 45 ° of the element (5) of shots (see Fig8). The purpose of this second cycle is to get a perfect view from above. After the translation of the shooting device (Z) and the rotation of the instrument (camera or scanner) (5), the tool is fixed, and the rotation of the individual sitting in an armchair on a motorized turntable along axis A2 according to an arc from 0 ° to 360 °. At this point, the second shot cycle is obtained (see Fig. 8). Combining these two cycles allows us to obtain a complete 3 D image. One of the goals is to have the measurements and the parameters of the face from every angle. The cycle can be interrupted at any time by the user, using a stop command of the device present on the device 30 or on a remote control. Once the shooting cycle has been completed, all the information is transmitted to the processing unit by means of communication means (8). The communication means (8) may be wireless transmission / reception means, or a wired connection such as a USB port. The individual and the user can then visualize on the screen of the apparatus the three-dimensional representation of the face and add the three-dimensional representation of a spectacle frame whose parameters have been adapted to the morphology of the face as illustrated. in Figure 13. The frame can be selected from a variety of frames. Some parameters of the same frame are then editable, for example, the color or pattern on the mount, the shape of the branches or the face of the frame, the thickness of the frame, etc. The scanning apparatus according to the invention makes it possible to reproduce the face of a person in three dimensions on a screen and to obtain digitized information of the shape of the face of the individual.
    [0030] This in order to: - manufacture a frame made of cellulose acetate or other natural materials wood etc ..., perfectly adapted to the morphology of an individual. The optimization of the shape of the frame is particularly obtained for the nasal support of the frame thanks to the nasal impression recorded by the device, as well as all the parameters of the face, or - to propose the best selection of spectacle frames in almost perfect harmony and adequacy with respect to the morphological parameters of the individual.
    [0031] The instrument for taking measurements and views associated with adhesive data sensors allows us to obtain all the parameters of the face (see Fig. 14 Fig. 15) .11 allows us to define: Af1: front angle right / Af2: left face angle / n: nasal width / 30 OD: right pupillary distance / OG: left pupillary gap / Ac1: right flush angle / Ac2: left flush angle. 3038078 21 s1: distance between the center of the right pupil and the base of the right eyebrow s2: distance between the center of the left pupil and the base of the left eyebrow. pl: distance between the center of the right pupil and the top of the right cheek. p2: distance between the center of the left pupil and the top of the left cheek. h: nasal height. (R): the gap between the right rock and the left rock. This measurement is carried out thanks to the sensors c10 and c15 (A): the upper ear gap. This measurement is carried out thanks to sensors c9 and c14. (T): the temporal gap. This measurement is carried out thanks to sensors c8 and c13. (S) the sphenoidal gap. This measurement is carried out thanks to sensors c7 and c12. Acr: peak angle. (C1) the arc of circle which defines the morphological curve of the individual. This measurement is carried out using sensors C1 and C4 (see Fig. 16). All these steps will be taken in one step. As it is both an instrument of measurement and shooting we will get the parameters on the customer's face in 3D. (see figl 5). We will have a superposition between the measurements and the 3-dimensional face. The technical aspect: eyeglass frames also have dimensions. So in the case of a selection, the goal is the best match between the parameters of the face and those of the mount. The second case, depending on the information collected by our instrument is the realization of a custom mount that will integrate all the asymmetries, (which are generally low), 3038078 22 which will bring a real quality of comfort and which visually will be aesthetic. When we have chosen eyeglass frames, we will focus solely on the aesthetic aspect.
    [0032] 5 The face that has been modeled in 3D will move with the frame of glasses which will also have been modeled. We will have a superposition of the 2 modelizations. The modeling of the glasses is done according to 2 principal and complementary axes. This is the condition for obtaining a 3 dimensional image. the top view is very important when shooting a mount because it allows us to get the shape of it. which should be parallel to the curve of the individual's forehead (as part of a custom spectacle frame) (see Fig. 16) No eyeglass frame manufacturer takes into account the 15 asymmetries of the nose which may be low, not visually obvious, but if corrected in the manufacture of eyeglass frames would provide excellent comfort. Depending on the different parameters collected by our tool, we will be able to manufacture a customized frame. The idea was that each individual with these peculiarities of his morphology, must have unique and perfectly adapted glasses. We are in a process and a reflection where the comfort of wearing a frame must be optimal for each face; there will always be a form that will be better than the others and that independently of fashions and styles. This is why the study of faces is so important, their shapes their proportions and the particular location of each constituent element. Let us take for example: the mounts, sometimes have high tenons, sometimes low tenons, sometimes very low, we have seen that the ears can be situated more or less high with respect to the pupillary line. It is ridiculous to sell a mount with high tenons to a person whose ears are very low and vice versa, from low tenons to one whose ears are well above the average position. The experienced optical optician knows how to identify the morphological elements and it is not uncommon that the first model he proposes is the one that best suits him. Our goal being that even a beginner optician eyewear, thanks to our instrument of measurements and views will be able to propose to his customer the best mounts of his store and thus to avoid the errors of choice.
    [0033] Basically all the art of optician eyewear is to adapt his technique to the visual requirements and anatomical data of each individual. Our 3D measurement and viewing device will allow us: 15 1) To have the best choice of glasses. 2) Or Make custom glasses.
