    The invention relates to a camera system for producing panoramic images, comprising a frame on which a plurality of cameras are fixed, which are oriented in different directions.
    It is known to produce panoramic images, both in the field of photography and in the field of film in that several cameras are mounted on a common frame and oriented in different directions. As a result, it is possible, for example, to cover a strip-shaped area which extends at an angle of 360 ° around the camera system. However, it is also possible to spatially arrange the cameras in such a way that the entire solid angle around the system is covered. Such a solution is described in CN 20255444 U.
    When editing the images, the frames taken by the cameras are combined to obtain a continuous panorama image.
    For reasons of space, the individual cameras must necessarily be arranged outside an imaginary center of the frame. This requires that the image angle of the individual cameras must be slightly larger than the angular distance of the cameras to avoid gaps in the image. This effect is the stronger, the closer the objects to be photographed are arranged to the camera system. However, this results in a so-called parallactic error, which is disturbing when assembling the individual images.
    Object of the present invention is to avoid these disadvantages and to provide a camera system that allows panoramic images with the highest quality even if the recording objects have very different distances from the camera system.
    According to the invention, these objects are achieved in that the cameras are surrounded by a spatial lens with several sections, which are each assigned to a camera and which are substantially adjacent to each other.
    It is essential to the present invention that virtually the entire surface of the spatial lens is used optically within the recording area, so that the solid angle segments of the individual cameras, taking into account the two-third
    Spatial lens in the center of the camera system coincide. This ensures that even if in an overlap area between two cameras both relatively close objects and distant objects are present, an assembly of the highest quality images is possible.
    In a first embodiment of the present invention, it is provided that the individual sections of the spatial lens are designed as convex lenses. As a result, a high optical quality can be achieved.
    According to a second embodiment of the present invention, the individual portions of the space lens are formed as Fresnel lenses, each corresponding to a convex lens. As a result, the thickness of the spatial lens and thus also the weight of the entire device can be substantially reduced.
    A particularly advantageous embodiment provides that a first group of cameras are arranged in an equatorial plane at regular angular intervals and that a second group of cameras each have optical axes which are arranged at a predetermined angle to the equatorial plane. For example, the first group of cameras may include six cameras, each covering a horizontal viewing angle of 60 °. This covers a strip-shaped image area that extends horizontally around the camera system in a typical recording situation.
    A second group of cameras has optical axes lying, for example, on a cone with an opening angle of 70 ° to 90 °, whose axis is arranged at right angles to the equatorial plane. This means that each optical axis of the second group of cameras includes an angle of 45 ° to 55 ° with this equatorial plane. The second group of cameras may include, for example, three cameras. The second group of cameras thus covers, for example, the spherical cap above the receiving area of the first group of cameras.
    Of course, analogously to the second group of cameras, a third group of cameras may additionally be provided which detects the area below the detection area of the first group of cameras. 3/13 3
    When using extreme space lens segments capable of imaging at least one hemisphere, it is possible to obtain a complete PanOramS image with only two cameras,
    Preferably, it can be provided that the Fresnel lenses have a plurality of rings whose image areas overlap each other. This makes it possible to combine the individual annular image sections in the image processing in such a way that no recognizable image errors due to the rings occur. This so-called " stitching " can be performed at high speed and with very good quality, since the properties of the lens are known and can be considered in advance in the algorithm.
    As a result, the present invention will be explained in more detail with reference to the embodiment variants shown in the figures. Show it:
    1 shows schematically a camera system according to the invention in one
    Lateral view, in which the clearing lens is removed for clarity;
    FIG. 2 shows the camera system of FIG. 1 from the front, here with the version of the spatial lens; FIG.
    FIG. 3: the spatial lens of the camera system of FIGS. 1 and 2; FIG.
    4 shows an embodiment of a spatial lens in section; and
    Fig. 5 is a schematic representation for explaining the invention.
    The camera system of Fig. 1 consists of a frame 1 to which a plurality of cameras 2a, 2b, 2c, 2d, 2e, 2f, 2g, 2h, 2i and 2j are fixedly mounted. A first group of a total of six cameras 2a, 2b, 2c, 2d, two of which are not visible in FIG. 1, are arranged at uniform angular intervals of 60 ° in an equatorial plane 3. A second group of a total of three cameras 2e, 2f and 2g are arranged above the first group so that the optical axes lie on a cone with an opening angle of, for example, α = 80 °. 4/13 4
    Three further cameras 2h, 21 and 2j of a third group are directed obliquely downwards analogous to those of the second group.
    In Fig. 2, the socket 5 can be seen, which is fixedly connected to the frame 1 and a total of twelve forms approximately trapezoidal or rhombic window, each receiving a portion of a space lens, not shown here.
    In Fig. 3, the spatial lens 6 is shown in a view corresponding to FIG. 2. The individual sections 7c, 7d, 7e, 7g, 7h and 7j are designated analogously to the associated cameras 2c, 2d, 2e, 2g, 2h and 2j.
    As shown in Fig. 4, each of the portions 7d, 7g and 7j is formed as a Fresnel lens, which is preferably smooth outside and spherical. On the inside of the typical ring structure is formed. The Fresnel lenses are converging lenses, ie each correspond to a convex lens.
    In Fig. 5, the main operating principle of the present invention will be explained. By way of example, two cameras 2d and 2g are shown, which have optical axes 12d and 12g. The cameras 2d and 2g are each arranged at a distance d from a center M * Starting from an imaginary optical center lld and 11g of the cameras 2d and 2g, the image area within the spatial lens 6 given by the angle β extends from one Section of the version 5 to the other. Due to the effect of the spatial lens 6, the image area is reduced, so that it adjoins the image area of the adjacent camera 2d, 2g apart from the spatial lens 6, apart from a slight overlap in the area of the mount 5. The beams 10 delimiting the image area intersect at the center M of the camera system. The angle γ which these rays 10 include is smaller than the angle β due to the distance d.
    It is obvious that the socket 5 should be made as slim as possible in order to minimize the remaining parallactic error. Optionally, individual sections of the spatial lens can be integrally formed or adhesively bonded. In these areas, therefore, the frame can be omitted. 5.13
