Abstract

The invention discloses a fouling detection method, device and system for a camera lens, and the method comprises the steps: carrying out the feature extraction of a current frame image collected by a camera, and obtaining the current middle feature and the current segmentation feature of the current frame image; current comparison features are extracted from the current intermediate features and features of a previous frame of image collected by the camera, and the current comparison features represent associated features in the current intermediate features and the features of the previous frame of image; and according to the current segmentation feature and the current comparison feature, detecting the fouling condition of the camera lens. And the stain detection precision can be improved.

Description

technical field [0001] The present invention relates to the technical field of automatic driving, in particular to a method, device and system for detecting contamination of a camera lens. Background technique [0002] In recent years, with the commercialization of visual inspection methods, cameras have been widely used in various inspection and monitoring tasks. For some cameras used to identify road conditions, because they are installed outside the vehicle, they are often contaminated by raindrops, mud, dust, etc., and the corresponding visual perception results will be wrong. When it is determined that the camera is dirty, the lens needs to be cleaned and the function corresponding to the camera needs to be temporarily turned off. [0003] In the existing lens contamination detection methods, there is a problem of inaccurate contamination detection. SUMMARY OF THE INVENTION [0004] In view of this, embodiments of the present invention provide a contamination detect...
