Device for automatic vehicle body damage detection

A device for an automatic detection of damage to a bodywork of motor vehicles, wherein the device comprises at least one lighting module (2), to which a computing computer is attached on a rear wall and a front surface is a light source (10), to which at least one image capturing device (3) is mounted, and to which a measuring unit containing at least four sensors (4a), (4b), (4c) and (4d) is mounted on a side wall, the lighting module (2) being between 40 and 100 cm from a surface of a vehicle body (7) or workpiece (8), and the image capturing device (3) is a monochrome camera with a resolution of at least 3 Mpix with a hardware shutter release input, capable of synchronisation with the lighting module (2) and the image capturing device (3), lens of which is manually adjustable, whereby a focal length equivalent of the image capturing device (3) used has a focal length equivalent value EKo for the lens of the image capturing device (3) of 35 mm format corresponding to at least 10 times the ratio of the distance L of the lighting module (2) from the surface of the vehicle body (7) or workpiece (8) to the width S of the lighting module (2) expressed in mm, with the formula:

• EKo>=10*L/S, while a visible light source (10) is provided with a screen in the form of alternately contrasting light (11) and dark (12) bands with a width of 3 to 30 mm and a luminance ratio of adjacent bands in a maximum ratio of 10:1, using visible light with a luminance value of at least 200 cd/m2 for each type of structured bands, and a computer (5) based on data collected from the lighting module (2), image capturing devices (3) and at least four sensors (4a), (4b), (4c) and (4d) controls the movement of the lighting module (2) and the image capturing device (3), with the data from the computer (5) being stored in a computing cloud, where the data analysis process by a neural networks responsible for damage detection takes place.
