Abstract

The invention relates to an occlusion detection method and device, electronic equipment and a storage medium, and the method comprises the steps: obtaining an image feature statistical graph of a plurality of to-be-detected image blocks in a current video frame and an image feature statistical graph of a plurality of reference image blocks in a reference video frame; determining whether a target to-be-detected image block with abnormal image feature statistical graph change relative to the reference video frame exists in the current video frame or not; under the condition of determining that the target to-be-detected image block exists in the current video frame, performing edge detection on the target to-be-detected image block to obtain an edge detection result of the target to-be-detected image block; and according to the edge detection result, determining whether an image acquisition device for acquiring the current video frame is shielded or not. According to the embodiment of the invention, shielding detection of the image acquisition equipment can be effectively realized.

Description

technical field [0001] The present disclosure relates to the technical field of computer vision, and in particular to an occlusion detection method and device, electronic equipment, and a storage medium. Background technique [0002] Intelligent monitoring system has been widely used in various fields of national life. The monitoring area of ​​the intelligent monitoring system is initially set and adjusted when the image acquisition equipment (for example, a camera) is installed. If the image acquisition device is blocked, it will cause the intelligent monitoring system to fail to achieve the expected monitoring effect. Therefore, occlusion detection for image acquisition equipment is very important for intelligent monitoring systems. Contents of the invention [0003] The present disclosure proposes technical proposals of an occlusion detection method and device, electronic equipment, and a storage medium. [0004] According to an aspect of the present disclosure, a me...
