[0030] Please refer to figure 2 , figure 2 The flow chart of the object relocation method provided by the preferred embodiment of the present invention is shown. The target retargeting method includes the following steps:

[0031] Step S101, acquiring a plurality of potential targets in the missing frame image of the video, wherein the missing frame image is any frame image in the video except the starting frame image.

[0032]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 missing frame image can be any frame image except the starting frame image in the video collected by the UAV 100, and the target to be tracked in the missing frame image has been lost, that is to say, when the video collected by the UAV 100 When the target to be tracked is lost, a corresponding frame of image is a lost frame image, and at this time, the target to ...

[0070] Please refer to Figure 7 , Figure 7 A schematic block diagram of an object relocating apparatus 200 provided by an embodiment of the present invention is shown. The target relocation apparatus 200 includes a potential target acquisition module 201 , an encoding information acquisition module 202 , a specific target acquisition module 203 and an execution module 204 .

[0071] The potential target acquisition module 201 is configured to acquire multiple potential targets in the missing frame image of the video, wherein the missing frame image is any frame image in the video except the starting frame image.

[0072] In the embodiment of the present invention, the potential target acquisition module 201 may be used to execute step S101.

[0073] Please refer to Figure 8 , Figure 8 for Figure 7 A schematic block diagram of the potential target acquisition module 201 in the target relocating apparatus 200 is shown. The potential target obtaining module 201 include...

Abstract

The present invention relates to the field of computer vision, and provides a target relocation method and device, which are applied to unmanned aerial vehicles. The method includes: acquiring multiple potential targets in the missing frame image of the video; according to the color channel of the initial frame image, Obtain the first coded information and the second coded information, wherein the first coded information is the coded information of the target to be tracked, and the second coded information is the coded information of the background image; using the first coded information and the second coded information, multiple Potential targets are screened to obtain specific targets; 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. The invention solves the problem in the prior art that once the target is lost, the UAV cannot quickly relocate and track the target, can effectively avoid the situation of flight stop or false tracking, 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 relocation method and device. 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 obtain the motion trajectory of the non-specific target according to the first frame target image more accurately, and can perform short-term tracking calculation on the target to be tracked in real time. For the single target tracking problem, the current UAV tracking system mainly focuses on improving the short-term tracking pe...
