Embodiment Construction

[0073] The preferred embodiments of the present invention will be described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention.

[0074] Embodiments of the present invention provide a multi-target tracking method based on multi-track fusion, such as figure 1 shown, including:

[0075] S1. Determine multiple tracking targets according to the user's operation instructions, and track each tracking target based on image recognition technology;

[0076] S2. During the tracking process, if any tracking target fails to be tracked, obtain the first motion track generated by it in the first preset time period before the tracking failure; The second movement trajectory generated by it within the time period;

[0077] S3. Fusing the first motion trajectory and the second motion trajectory as a new moti...

Abstract

The invention provides a multi-target tracking method and system based on multi-track fusion. The method comprises the steps: determining a plurality of tracking targets according to an operation instruction of a user, and tracking each tracking target based on an image recognition technology; in the tracking process, if any tracking target fails to be tracked, acquiring a first motion track generated in a preset first time period before the tracking fails; acquiring a second motion track generated in a preset second time period after the tracking target is successfully tracked again; and fusing the first motion trail and the second motion trail to serve as a new motion trail. According to the multi-target tracking method and system based on multi-track fusion, the influence of the body of the user and the cue on the blocking of the billiard ball before and after the user uses the cue to hit the billiard ball on the track tracking is reduced, and therefore, the completeness of the track tracking is improved.

Description

technical field [0001] The invention relates to the technical field of video monitoring, in particular to a multi-target tracking method and system based on multi-track fusion. Background technique [0002] At present, image recognition technology is mostly used to track the billiard balls on the billiard table. However, the user's body and the cue will frequently block the billiard balls to varying degrees during the process of hitting the billiard ball with the cue. integrity is affected. Contents of the invention [0003] One of the objects of the present invention is to provide a multi-target tracking method and system based on multi-trajectory fusion. When a certain billiard ball fails to be tracked, the motion track generated before the tracking failure is compared with the track generated when the tracking fails and the tracking succeeds. The motion trajectory is fused to form a complete motion trajectory, which reduces the impact of the user's body and cue on the ...
