The invention discloses a video image interference detection method, system, computer equipment and medium. The method includes the following steps: acquiring a background image and a current frame image; respectively constructing edge maps of the background image and the current frame image; Taking the intersection of the edge map of the background image and the edge map of the current frame image to obtain the same boundary map between the edge map of the background image and the edge map of the current frame image; The first number of pixels in the edge map and the second number of pixels in the same boundary map; determine whether the current frame image is disturbed according to the ratio of the first number of pixels to the second number of pixels. The solution proposed by the invention can detect the interference behavior in the video monitoring system, can quickly identify the interference behavior in the video monitoring system, and alarm the interference behavior in time.
Description
technical field [0001] The invention relates to the field of video detection, in particular to a video image interference detection method, system, device and storage medium. Background technique [0002] In recent years, with the continuous improvement of video surveillance requirements, the demand for intelligent video surveillance has also increased. People have proposed the concept of intelligent video surveillance, and intelligent video surveillance technology has gradually developed. However, with the continuous development of intelligent video surveillance technology and the continuous increase of application requirements, the challenges faced by intelligent video surveillance systems are also increasing, and many new practical problems have been proposed and studied one after another. The problem of interference detection is one of them. . [0003] In practical applications, due to the objective environment, human factors or other reasons, a large number of various ...
