Abstract

The embodiments of the present invention provide a video tracking method, a video tracking device, an object recognition method and an object recognition device. With the devices and methods of the invention adopted, the problem of tracking object loss caused by the discontinuation of the tracking process of an existing video tracking method, and the problems of complex process and low efficiency of an existing object recognition method can be solved. The video tracking method includes the following steps that: a first tracking target in a video is determined, and video tracking is performed on the first tracking target based on the video; the area overlapping degree of the first tracking target in a current image and a first tracking target in a previous image in a video tracking process is calculated, wherein the previous image is an image obtained when the first tracking target was tracked recently before the first tracking target is tracked in the current image in the video tracking process; and the feature information of feature points of the first tracking target object in the video is extracted in the video tracking process of the first tracking target object.

Description

technical field [0001] The present invention relates to the technical field of video analysis, in particular to a video tracking method and device, and an object recognition method and device. Background technique [0002] Video tracking and recognition technology based on computer vision has been widely used in public security, identity verification and other occasions. For example, the whereabouts of suspicious objects can be grasped through continuous video tracking of suspicious objects in surveillance video, and the identity information of suspicious objects can be further grasped through intelligent identification of suspicious objects, thus providing powerful solutions for criminal investigation. clue. [0003] However, because the sampling frame rate of surveillance video is not high, and the camera may move violently during the sampling process, it is difficult for existing video tracking methods to complete continuous tracking of the same tracking object. When a ...
