Abstract

A damage monitoring method of image surveillance equipment comprises the following steps of: acquiring image data captured by the image surveillance equipment; calculating the current image texture histogram in the image data; when the number of texture histograms in a historical image record meets a predetermined storage set value, calculating difference values between the current image texture histogram and a first record and a second record of the texture histogram in the historical image record; when the calculated two difference values are both greater than a preset threshold value, determining the current image to be abnormal and increasing a warning value by one, wherein the warning value refers to the number of abnormal images when the warning is given; when the warning value is greater than a preset value, presenting warning information to warn a user that the current image surveillance equipment is damaged. The invention further provides a damage detecting system of the image surveillance equipment. With the method of the invention, whether the image monitoring device is destroyed can be detected automatically and timely.

Description

technical field [0001] The invention relates to a damage detection system and method, in particular to a damage detection system and method of image monitoring equipment. Background technique [0002] At present, video surveillance equipment can be seen everywhere. For example, cameras are installed in open environments such as office corridors, roadsides, airports, and station halls to monitor the flow of people around, so as to determine whether the objects that users care about have encountered threat, and thus effectively reduce the harm caused by the incident or threat. If these video monitoring equipment are damaged intentionally, such as the camera lens is sprayed, covered, out of focus, turned, etc., the personal or property safety of the user will not be guaranteed. Although the user can detect whether the video surveillance equipment has been damaged by viewing the image, this method is time-consuming and labor-intensive, and when the video surveillance equipment ...
