1. A vehicle surface analysis system, comprising:
a vehicle positioning unit;
an evaluation unit;
said vehicle positioning unit including a platform and a platform position detection unit, said platform being constructed for supporting a vehicle thereon, said platform being rotatable about a vertical axis of the placed vehicle, and said platform position detection unit being constructed for recording platform position data and providing the platform position data to the evaluation unit;
an optical image acquisition unit having individual image acquisition units and a positioning unit determining a positional relationship of said individual optical image acquisition units with respect to each other and with respect to said vehicle positioning unit, each of said individual image acquisition units having a respective light radiation source being constructed for providing a plurality of different radiation energy levels and a respective image camera, each of said individual image acquisition units having a respective image acquisition range covering a surface of the vehicle at least in sections, each of said individual image acquisition units having a respective wavelength work spectrum different from a wavelength work spectrum of another of said individual image acquisition units;
said individual image acquisition units being constructed for acquiring pixel data of an image acquisition of object points of the vehicle and for providing the pixel data to the evaluation unit, the pixel data containing wavelength-related and radiation energy level-related light intensity value data and coordinate data of the object points;
said evaluation unit including a difference value generation module, a difference value assessment module, an overall assessment module and a generation module;
said difference value generation module being configured for mapping the light intensity value data of the image acquisition for an object point by the associated coordinate data to the light intensity value data of at least one further image acquisition for a same object point, said difference value generation module being configured comparing the light intensity value data in a light intensity value data comparison and for generating difference value data therefrom and providing the difference value data to the difference value assessment module;
said difference value assessment module being configured for carrying out an evaluation of a quality of the difference value data and, on the basis of the evaluation, for carrying out a categorization in usable difference value data when an adjustable quality value of the difference value quality is reached and in non-usable difference value data when the quality value is not reached, and for providing usable difference value data to the overall assessment module;
said overall assessment module being configured for using the coordinate data for the object points for mapping the usable difference value data from the light intensity value data comparison to further usable difference value data from a further light intensity value data comparison for performing a comparison of the quality value of the usable difference value data from the light intensity value data comparison with the quality value of the further usable difference value data from the further light intensity value data comparison, and for performing a weighting of the usable difference value data, depending on the quality value, as weighted difference value data;
said generation module being configured for mapping the coordinate data from the pixel data to a uniform spatial coordinate system by including the platform position data for generating a digital surface contour image of the vehicle in the uniform spatial coordinate system for supplementing the digital surface contour image of the vehicle by adding the weighted difference value data on the basis of the coordinate data for creating a digital surface quality image of the vehicle, said generation module being configured for providing the digital surface quality image in a displayable manner;
a comparison module including a database with data on a normative digital surface condition image, said comparison module being configured for carrying out a comparison between the digital surface condition image and the normative surface condition image and for generating a digital difference image;
a repair calculation module having a database with repair data, the repair data including data on spare parts, repair work times and repair costs, said repair calculation module being configured for generating a repair assessment on the basis of the digital difference image and the repair data, the repair assessment including spare parts required for a repair, repair work times to be spent and repair costs.
