Problems solved by technology

[0002] With the development of science and technology, the number of cameras in a medium-sized city surveillance system is as many as tens of thousands, and due to human or external factors, foreign objects such as leaves and clothes often block the surveillance cameras, which will cause different levels of surveillance information. The absence of occlusion can easily cause irreversible consequences to related business applications, so occlusion detection is an important content in video surveillance systems

Abstract

The invention discloses a shielding detection method and device for a monitoring device and a storage medium. The method comprises the steps of: dividing a to-be-detected image after the to-be-detected image is received, and obtaining a plurality of image blocks; obtaining a judgment result indicating whether shielding exists in the plurality of image blocks and weights of the plurality of image blocks; calculating scores of the plurality of image blocks according to judgment result and weights of the plurality of image blocks; calculating the total score of the to-be-detected image according to the scores of the plurality of image blocks; and according to the total score of the to-be-detected image, judging whether the to-be-detected image is shielded or not. The shielding detection method provided by the invention can improve the accuracy of shielding detection.

Description

technical field [0001] The present application relates to the technical field of image processing, and in particular to an occlusion detection method of a monitoring device, a detection device and a storage medium. Background technique [0002] With the development of science and technology, the number of cameras in a medium-sized city surveillance system is as many as tens of thousands, and due to human or external factors, foreign objects such as leaves and clothes often block the surveillance cameras, which will cause different levels of surveillance information. The lack of occlusion will easily cause irreversible consequences to related business applications, so occlusion detection is an important content in video surveillance systems. Contents of the invention [0003] The main technical problem to be solved by the present application is to provide a occlusion detection method for a monitoring device, a detection device and a storage medium, which can improve the acc...
