Abstract

The invention relates to a camera movement identification method, device and equipment and a computer readable storage medium. The camera movement identification method comprises the following steps: acquiring an image frame sequence, and determining a dense optical flow field of each image frame in the image frame sequence; the dense optical flow field of each image frame is clustered, a main optical flow field and a sub optical flow field of each image frame are determined, and the main optical flow field and the sub optical flow field are clustered sub optical flow fields classified by most pixels in each image frame; calculating a mean optical flow vector of the main optical flow field and the sub optical flow field of each image frame; and judging whether the camera moves or not according to the mean optical flow vector of each image frame. Through the method and the device, the problem of low accuracy of camera movement recognition in related technologies is solved, and the accuracy of camera movement recognition is improved.

Description

technical field [0001] The present application relates to the field of image processing, and in particular, to a method, apparatus, device, and computer-readable storage medium for recognizing camera movement. Background technique [0002] In surveillance systems, camera movement is a relatively common operation, but it has very adverse consequences for intelligent video analysis. Because most of the current intelligent video analysis systems have the assumption that the camera is still, and then design a motion detection method similar to background modeling, and even set some regular areas that are very related to the current scene. Once the camera moves, these strategies will no longer be applicable, and will eventually bring a large number of false positives or false negatives to users. [0003] At present, the main method of detecting camera movement still relies on the comparison of images before and after the movement. Generally, some matching features are extracted....
