Testing and validation of a camera under electromagnetic interference

1. A system for camera validation comprising:

a camera configured to capture an image of a content object; and

a processor programmed to:

receive a signal indicative of the image of the content object during an electromagnetic event;

generate an image quality score of the image; and

generate a validation status of the camera based on a comparison of the image quality score to a validation threshold, the validation status of the camera being indicative of whether the electromagnetic event interrupted normal functioning of the camera.

2. The system of claim 1 , wherein the processor is further programmed to:

receive a second signal indicative of a second image of the content object during a normal condition, wherein the normal condition does not include the electromagnetic event; and

generate a second image quality score of the second image, wherein the validation threshold is based on the second image quality score.

3. The system of claim 1 , wherein the image quality score comprises a structural similarity index (SSIM) score.

4. The system of claim 1 further comprising an electromagnetic interference device configured to cause the electromagnetic event.

5. The system of claim 1 , wherein the electromagnetic event comprises at least one of a radiated immunity event, a radiated emissions event, and a conducted emissions event.

6. The system of claim 1 , wherein the content object comprises high-frequency content that provides informational and visual content.

7. The system of claim 1 , wherein the content object comprises a spilled coins image.

8. The system of claim 1 , wherein the image of the content object during the electromagnetic event comprises a first region and a second region spaced apart from the first region, and wherein the processor is further programmed to:

generate a first region image quality score indicative of the image quality of the first region;

generate a second region image quality score indicative of the image quality of the second region; and

generate the validation status of the camera based on a comparison of at least one of the first region image quality score and the second region image quality score to the validation threshold.

9. The system of claim 8 , wherein the processor is further programmed to:

generate a passing validation status in response to both the first region image quality score and the second region image quality score being less than the validation threshold.

10. The system of claim 1 , wherein the processor is further programmed to:

generate a passing validation status in response to the image quality score being less than the validation threshold.

11. An autonomous vehicle system comprising:

at least one camera validated by the system of claim 1 , wherein the at least one camera is configured to mount to a vehicle to capture an environment image indicative of an environment external to the vehicle; and

a controller programmed to control at least one of a braking system, a steering system, and an infotainment system based on the environment image.

12. The autonomous vehicle system of claim 11 , wherein the at least one camera comprises a front-facing camera and the environment image is indicative of the environment in front of the vehicle; and

wherein the controller is further programmed to control the braking system based on the environment image.

13. The autonomous vehicle system of claim 11 , wherein the at least one camera comprises a rear-facing camera and the environment image is indicative of the environment behind the vehicle; and

wherein the controller is further programmed to control the infotainment system to display the environment image on a display screen.

14. The autonomous vehicle system of claim 11 , wherein the at least one camera comprises a roof-mounted camera and the environment image is indicative of a field-of-view about the vehicle; and

wherein the controller is further programmed to control the steering system to navigate the vehicle around obstacles based on the environment image.

15. A method for validating a camera comprising:

exposing a camera to electromagnetic interference during an electromagnetic event;

capturing, by the camera, an image of a content object during the electromagnetic event;

receiving a signal indicative of the image of the content object;

generating an image quality score of the image; and

generating a validation status of the camera based on a comparison of the image quality score to a validation threshold, the validation status of the camera being indicative of whether the electromagnetic event interrupted normal functioning of the camera.

16. The method of claim 15 , further comprising:

receiving a second signal indicative of a second image of the content object during a normal condition, wherein the normal condition does not include the electromagnetic event; and

generating a second image quality score of the second image, wherein the validation threshold is based on the second image quality score.

17. The method of claim 15 , further comprising:

generating a passing validation status in response to the image quality score being less than the validation threshold.

18. A non-transitory computer-readable medium storing computer-executable instructions which when executed by one or more processors result in performing operations comprising:

controlling a camera to capture an image of a content object during an electromagnetic event;

generating an image quality score of the image; and

generating a validation status of the camera based on a comparison of the image quality score to a validation threshold, the validation status of the camera being indicative of whether the electromagnetic event interrupted normal functioning of the camera.

19. The non-transitory computer-readable medium of claim 18 , wherein the operations further comprise:

controlling an electromagnetic interference device to cause the electromagnetic event.

20. The non-transitory computer-readable medium of claim 18 , wherein the operations further comprise:

controlling the camera to capture a second image of the content object during a normal condition, wherein the normal condition does not include the electromagnetic event; and

generating a second image quality score of the second image, wherein the validation threshold is based on the second image quality score.
