| Summary: | The invention discloses a camera stain detection method and a related device, and the method comprises the steps: obtaining a target image obtained through the shooting of a target region by a camera, and converting the target image into a brightness image; wherein the surface of the target area is flat and has the same color; performing edge detection on the brightness image to obtain an edge expansion image, and performing brightness screening on the brightness image to obtain a dark pixel image; and combining the edge expansion image and the dark pixel image to obtain a stain detection image. Through the above mode, the accuracy of stain detection can be improved, leak detection of stains is reduced, the possibility of detecting halo or dark corners as stains is reduced, and the efficiency of stain detection is improved.
