Vehicle camera lens obstruction

A vehicle camera lens obstruction detection system comprising:

• a vehicle camera mounted on a vehicle, the vehicle camera including a lens, and the vehicle camera configured to capture images;
• and
• a vehicle control module in communication with the vehicle camera, the vehicle control module configured to:
• receive a sequential feed of multiple frames from the vehicle camera;
• extract and track at least one salient region in the multiple frames;
• detect at least one blockage area of the vehicle camera according to the at least one salient region;
• generate a camera lens dirt map according to the at least one blockage area;
• and
• initiate at least one of automated lens cleaning or a camera lens obstruction signal, according to the camera lens dirt map.
