Is using the camera OAK-1 as a door sensor with object detection.
Due to the standards in the door area, a sensor must be tested regularly.
How can I tell that the camera sees something when there is no object in the picture?
Lets assume someone sticks something over the camera and the camera sees nothing (resp. the image is black).
Another thing to consider would be that the lighting conditions change throughout the day.
My idea would be to regularly save an image when there is no object in the frame and then regularly compare that to the current image.
That way I can tell that the camera is seeing something (and also that it hasn't been taped over) but it's not a test to the standard.
Is there a way to test the camera's sensor for function? Or do I have to generate a test signal externally that then appears in the camera image?
thank you in advance for your help and information
