Abstract

In a target tracking method and device provided by the embodiment of the present invention, the zoom coefficient and translation amount of the first frame image and the current frame image of the tracking target are obtained; The value is greater than the first preset threshold, and the difference between the translation amount of the current frame image and the previous frame image is smaller than the second preset threshold value, then based on the zoom coefficient and the translation amount, the position and the position of the tracking target in the current frame image are obtained. size, otherwise, the size of the tracking target position of the previous frame image of the current frame image is used as the result of the current frame image. The position and size of the target in the current frame are calculated according to the zoom coefficient and translation amount, and a zoom calculation module is added. For scenes with zoom, the target can be tracked more stably; with higher performance, the target may be tracked faster and meet the needs of high frames. rate requirements; increase the confidence decision strategy to reduce drift.

Description

technical field [0001] Embodiments of the present invention relate to the field of computer technologies, and in particular, to a target tracking method and device. Background technique [0002] Object tracking is an important research direction in the field of vision. With the popularization of deep learning, performance has increasingly become a restrictive factor. Target tracking is a comprehensive application technology that integrates various technologies such as image processing, pattern recognition, artificial intelligence and automatic control, and is widely used in various fields. Target tracking refers to the detection, recognition and tracking of moving targets or objects with a single feature in an image sequence. Accurate tracking of moving objects. [0003] In the research field of target tracking, many scholars have proposed a large number of tracking methods. In these tracking methods, the tracking frame is often used to track the tracking target, but in th...
