Problems solved by technology

[0004] However, in a scenario involving multiple tracking devices, when a moving object moves from the coverage area of ​​one tracking device to the coverage area of ​​another tracking device, the other tracking device cannot , lock the moving target in time, cannot accurately track the same moving target, the moving target will be lost, and the linkage between multiple tracking devices is poor

Embodiment Construction

[0035] Aiming at the problems existing in the prior art, an embodiment of the present invention proposes a method for tracking a moving object, which can be applied to a system including a management server (such as a three-dimensional server, etc.) and multiple tracking devices (such as a tracking ball machine, etc.) In a video surveillance system, and the method can be applied to a management server. In the above application scenarios, such as figure 1 As shown, the tracking method of the moving target may specifically include the following steps:

[0036] Step 101, constructing a virtual three-dimensional environment corresponding to the tracking scene, and constructing a virtual tracking device in the virtual three-dimensional environment corresponding to the actual physical position of the real tracking device. Wherein, each virtual tracking device corresponds to a coverage area, and overlapping areas may exist in the coverage areas corresponding to different virtual tra...

Abstract

The invention provides a moving object tracking method and device. The tracking method comprises that a virtual 3D environment corresponding to a tracking scene is established, and virtual tracking devices are established in the virtual 3D environment corresponding to the practical physical positions of real tracking devices; in the process that the first real tracking device tracks a moving object, practical position information of the moving object in a practical image is received from the first real tracking device, and a first 3D coordinate of the moving object in the virtual 3D environment is determined by utilizing the practical position information; whether the first 3D coordinate is within the overlapped area of the coverage areas of the first and second virtual tracking devices is determined; and if yes, the moving object is determined to move to the coverage area of the second real tracking device corresponding to the second virtual tracking device, and the second real tracking device is notified of tracking the moving object. According to the technical scheme of the invention, the same moving object can be tracked accurately, and is prevented from tracking failure.

Description

technical field [0001] The invention relates to the field of video technology, in particular to a method and device for tracking a moving target. Background technique [0002] In recent years, with the rapid development of computers, networks, image processing, and transmission technologies, the trend of popularization of video surveillance has become more and more obvious. Video surveillance is gradually becoming high-definition and intelligent. Video surveillance systems can be used in many fields. Such as intelligent transportation, smart park, safe city, etc. [0003] In a video surveillance system, a tracking device (such as a track ball machine, etc.) is an important part of the video surveillance system, and the tracking device can already track a moving target based on an automatic locking method or a manual locking method. Wherein, when the moving target moves within the coverage area of ​​the tracking device, the tracking device can always lock on the moving targe...
