Embodiment Construction

[0071] In the following description, specific details such as specific system structures and technologies are presented for the purpose of illustration rather than limitation, so as to thoroughly understand the embodiments of the present invention. It will be apparent, however, to one skilled in the art that the invention may be practiced in other embodiments without these specific details. In other instances, detailed descriptions of well-known systems, devices, circuits, and methods are omitted so as not to obscure the description of the present invention with unnecessary detail.

[0072] In order to illustrate the technical solutions of the present invention, specific examples are used below to illustrate.

[0073] As described in the background art, the existing video target tracking method has the following defects: when the target moves too fast, the problem of tracking failure may occur.

[0074] After research, the applicant found that the existing video target tracki...

Abstract

The invention is suitable for the technical field of computers, and provides a target tracking method, device and equipment and a storage medium, and the target tracking method comprises the steps of obtaining a target video frame of a video containing a to-be-tracked target; filtering the target video frame according to the mark information of the to-be-tracked target to obtain confidence coefficient data of the to-be-tracked target at each position in the target video frame; predicting a moving target position of the to-be-tracked target in the target video frame according to the historical position information of the to-be-tracked target in the historical video frame; constructing a Gaussian matrix taking the position of the moving target as the center under the condition that the confidence coefficient data meets the non-occlusion condition, and determining a search center of a to-be-tracked target in the target video frame according to the Gaussian matrix and the confidence coefficient data; and intercepting a search area from the target video frame according to the search center and a preset search area size, and extracting position information of the to-be-tracked target in the search area. According to the invention, the tracking performance can be improved.

Description

technical field [0001] The invention belongs to the technical field of computers, and in particular relates to a target tracking method, device, equipment and storage medium. Background technique [0002] Video target tracking is an important direction in computer vision. It mainly studies how to continuously extract the position of the target to be tracked in the video frame according to the information of the target to be tracked given by the reference video frame in the video, so as to obtain the motion of the target to be tracked. trajectory, such as figure 1 As shown, the video frame to be tracked can be tracked by the tracking device to obtain the motion track of the target to be tracked. Video object tracking has many applications in daily life, such as unmanned driving, video surveillance, human-computer interaction, etc. [0003] However, when the target to be tracked moves too fast, the existing video target tracking method may fail to track the target to be trac...
