AUTOMATED CAMERA WASH FOR VEHICLES

摘要

A system to remove debris from a vehicle camera lens using washer fluid from the vehicle's washer system is disclosed. The system analyzes a captured image and determines if the image is obstructed by debris. If the image is determined to be obstructed, the system automatically sprays the camera lens with fluid to remove the debris. The system includes a method of determining obstruction by comparing an image with a reference image. The system includes a method of determining obstruction by analyzing relative movement within a reference area of the image. The system also prevents the draining of the washer fluid due to a false obstruction reading or debris that does not come off after a few sprayings.
