[0033] Please refer to figure 2 , figure 2 A flow chart of the object re-detection method provided by the embodiment of the present invention is shown. The object re-detection method includes the following steps:

[0034] Step S101, acquiring a plurality of potential targets in the first image of the video, wherein the first image is any frame image in the video except the initial frame image.

[0035] In the embodiment of the present invention, the video may be a video collected by the UAV 100 , for example, an aerial video of geographical features, landscapes, people, and the like. The first image can be any frame image except the initial frame image in the video collected by the UAV 100, and the object to be tracked in the first image has been lost, that is to say, the object to be tracked in the first image needs to be re-detected. track target. The potential target may be, but not limited to, a foreground target similar to the target to be tracked that needs to be r...

Abstract

The present invention relates to the field of computer vision technology, and provides a target re-detection method, device, and unmanned aerial vehicle. The method includes: acquiring a plurality of potential targets in the first image of the video, wherein the first image is the first image in the video Any frame of image other than the initial frame image; according to the color characteristics of each potential target, multiple potential targets are screened to obtain a specific target; according to the similarity between the specific target and the target to be tracked, it is judged whether the specific target is the target to be tracked , wherein the target to be tracked is determined by the initial frame image, the invention solves the problem in the prior art that the UAV cannot quickly relocate the target when the tracking target is lost, and has the advantages of high efficiency and high accuracy.

Description

technical field [0001] The present invention relates to the technical field of computer vision, in particular to a target re-detection method, device and unmanned aerial vehicle. Background technique [0002] Moving target tracking technology is a high-tech subject that integrates multiple fields such as image processing, pattern recognition, artificial intelligence, and automatic control. It is also one of the key technologies for realizing intelligent robots and intelligent weapons. It has broad applications in many fields. Application prospects and practical significance, for example, applied to UAV target tracking. [0003] The modern UAV tracking system has been able to accurately obtain the motion trajectory of the non-specific tracking target based on the first frame of the target image, and can perform short-term tracking calculations on the target to be tracked in real time. For the single target tracking problem, the current UAV tracking system mainly focuses on i...
