Abstract

Claims (25)

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.

2. The test setup according to claim 1 , wherein the autostereoscopic screen is configured to generate a stereo effect on a pixel basis and via devices mounted on the screen surface.

3. The test setup according to claim 2 , wherein the devices mounted on the screen surface are designed as lenticular grids and/or parallax barriers.

4. The test setup according to claim 1 , wherein the autostereoscopic screen is configured to spatially separate the first and second image data on a pixel basis and via devices mounted on the screen surface.

5. The test setup according to claim 4 , wherein the devices mounted on the screen surface are designed as lenticular grids and/or parallax barriers.

6. The test setup according to claim 4 , wherein, from the simultaneously output first and second image data, the first image data is detectable by the first optics of the stereo camera, and the second image data is detectable by the second optics of the stereo camera.

7. The test setup according to claim 6 , wherein the computing unit is configured to generate the synthetic image data using parameters of the stereo camera.

8. The test setup according to claim 1 , wherein depth information is determinable on the basis of the stereo image.

9. The test setup according to claim 1 , wherein the computing unit is configured to generate the synthetic image data and to output the synthetic image data on the autostereoscopic screen in such a way that depth information is determinable based on the stereo image detected by the stereo camera.

10. The test setup according to claim 1 , wherein the test setup has an interface for receiving data which are dependent upon the image data detected by the stereo camera.

11. A method for testing a stereo camera of a vehicle, wherein the stereo camera comprises first optics and second optics disposed at a distance O from one another, the method comprising:

a) generating, by a test setup, synthetic image data, 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;

b) outputting, by the test setup, the synthetic image data on an autostereoscopic screen; and

c) detecting, by the stereo camera, the synthetic image data output on the screen as a stereo image;

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.
