Problems solved by technology

The disadvantage of this method is also obvious. The accuracy of leaf occlusion detection is too low. Because the leaf depth information cannot be obtained, it is often interfered by large leaves in the distance and other playgrounds and lawns with similar colors to the leaves. Misjudgment occurs. Therefore, Still need manual review

Abstract

The invention relates to a method and device for detecting shielding of monitoring equipment by a foreign matter. The method comprises the following steps: obtaining an original image by using a camera; processing the original image to detect a target pixel associated with a foreign matter; if the target pixel is detected, extracting the target pixel in the original image to obtain an image with the reserved target pixel; performing depth estimation on the image with the reserved target pixel; calculating an occlusion ratio based on a result of the depth estimation; and judging whether the camera is shielded by a foreign matter based on the shielding ratio.

Description

Technical field [0001] The present disclosure relates to the field of video image processing, and in particular, to a method and apparatus for detecting monitoring equipment is blocked by foreign matter. Background technique [0002] With the rapid development of modern technology, the gradual development and improvement of image and video acquisition technology, smart security video surveillance has been widely used in people's daily production life. These security video surveillance cameras are easily blocked, resulting in serious deletions of monitoring points monitoring information, which will not only seriously affect the function of monitoring the camera, weaken public security organs to use video inspections, investigations, will also cause serious public safety management Impact, threatening the lives and property of residents, and may even cause irreparable losses in some key monitoring points. [0003] At this stage, the detection camera is mainly involving two methods:...
