The present invention provides a lens attachment detection system, terminal and storage medium, including the following steps: S01: image segmentation: segment the suspected region of the input image; S02: feature extraction: extract the blurred contour area caused by the attachment, and Perform statistical calculations on multiple definition evaluation indicators within the outline, and determine whether the area is an attachment based on the results of multiple indicators; S03: Early warning judgment: cumulatively mark the judgment area, and perform early warning trigger judgment on the processing results of the accumulated times exceeding the alarm threshold . In order to ensure the normal operation of the auxiliary system and the safety of the user's vehicle body, the invention solves the problem that the lens is blocked by water droplets of different shapes or the lens is blocked by dark stains, light spots, refracted light, etc., detects and alarms in time. |
