1. A method for evaluating with a camera simulation device operability of an object recognition device of a motor vehicle, comprising the steps of: providing reference image data generated with a camera for at least one route; generating with the camera simulation device simulation image data for the at least one route; comparing the simulation image data with the reference image data based on at least two different predetermined comparison measures; determining a value for each of the at least two comparison measures independent of processing of the data by the object recognition device; forming at least one comparison value for each comparison measure; checking if a totality of the formed comparison measures satisfies a predetermined validation criterion; and when the predetermined validation criterion is satisfied, providing the camera simulation device for use in evaluating the operability of the object recognition device.
