Abstract

The invention provides a camera position deviation detection method and device. The camera position deviation detection method comprises the following steps that a plurality of feature objects are installed in advance, an initial position coordinate of each feature object is recorded, and feature object template images are stored; images at present are acquired, matched images which are matched with the feature object template images are obtained from the images at present through matching, and candidate position coordinates of the matched images are acquired; the number of feature point matching pairs meeting the preset conditions is obtained according to the initial position coordinate of each feature object and the candidate position coordinates of the matched images, and whether the position of a camera deviates from the standard position or not is judged according to the result of comparison between the number of the feature point matching pairs and the preset number. The invention further provides the camera position deviation detection device. The camera position deviation detection device comprises a feature object template storage module, an image acquisition module and a position deviation judgment module.

Description

technical field [0001] The invention belongs to the technical field of image processing, and in particular relates to a camera position deviation detection method and equipment. Background technique [0002] Camera position detection technology is a very important technology in the field of video or image processing. Many intelligent monitoring, intelligent tracking and intelligent recognition systems need to be analyzed based on the images collected by the camera, and then follow-up based on the obtained analysis results. processing and control. Therefore, whether the installation position of the camera is correct or not has a very important influence on the correctness of the subsequent results of the system. [0003] The position of the camera will be corrected during the initial installation of the camera, but as the camera is used later, the position will shift. Therefore, there is a need for a method and device that can automatically detect the position of the camera...
