1. A test setup for testing a stereo camera for a vehicle, wherein the test setup comprises:
a computing unit; and
an autostereoscopic screen;
wherein the computing unit is configured to generate synthetic image data and to output the synthetic image data on the autostereoscopic screen in such a way that the image data is detectable by the stereo camera as a stereo image;
wherein the stereo camera comprises first optics and second optics disposed at a distance from one another; and
wherein generating the synthetic image data is based on a simulation model that simulates vehicle surroundings, including a plurality of objects in the vehicle surroundings, and wherein in the simulation model, an ego vehicle comprises a virtual stereo camera having two virtual mono cameras at the same distance from one another as the first and second optics of the stereo camera;
wherein the synthetic image data output on the autostereoscopic screen includes first image data corresponding to the first optics and second image data corresponding to the second optics, and wherein the first image data and the second image data are simultaneously output;
wherein the test setup is part of a test bench for testing the vehicle; and
wherein the vehicle has a radar sensor, an ultrasonic sensor, a further camera, and/or a LIDAR sensor, and the test bench has a further test setup for testing the radar sensor, the ultrasonic sensor, the further camera, and/or the LIDAR sensor.
