Embodiment 1

[0033] It should be noted that the target tracking method provided by the embodiment of the present invention can be applied to a motorized pan-tilt camera, and can also be applied to a fixed pan-tilt camera, so as to track the target object in each video frame in the video stream collected by the camera. detection and tracking.

[0034] figure 1 Show the flowchart of the object tracking method of the embodiment of the present invention, as figure 1 As shown, the method may include the following steps:

[0035] S101: Acquire first position information and first feature information of a first target object in a first image. Here, it should be noted that the first target object refers to all target objects in the first image, that is, there may be one or more first target objects, and the first image refers to a video stream except the first frame Any video frame other than .

[0036] Here, the first position information and first feature information of the first target obje...

Embodiment 2

[0084] It should be noted that the gun ball linkage tracking method provided by the embodiment of the present invention can be applied to such as Image 6 In the gun-ball linkage system shown, it is used to track moving target objects, such as Image 6 As shown, the pan / tilt is connected with the gun camera and the dome camera, and the pan / tilt is the installation pan / tilt of the dome camera, and is used to control the shooting of the dome camera installed on it according to the control command of the gun camera.

[0085] Figure 7 Shows the flow chart of the gun-ball linkage tracking method of the embodiment of the present invention, as Figure 7 As shown, the method may include the following steps:

[0086] S701: The trigger detects a moving target, and extracts position information of the moving target. Here, the position marker information of the moving target is obtained by the gun machine using the moving target detection algorithm to detect the video stream of the gu...

Embodiment 3

[0092] Figure 8 A functional block diagram of an object tracking device according to an embodiment of the present invention is shown, and the device can be used to implement the object tracking method described in Embodiment 1 or any optional implementation manner thereof. Such as Figure 8 As shown, the device includes: a first information acquisition module 10 , a second information acquisition module 20 , a first calculation module 30 , a second calculation module 40 , a target judgment module 50 and a tracking target determination module 60 .

[0093] The first information acquiring module 10 is configured to acquire first position information and first characteristic information of the first target object in the first image.

[0094] The second information obtaining module 20 is used for obtaining the second position information and the second feature information of the second target object in the second image, where the second image is the previous frame image of the f...

Abstract

The invention discloses a target tracking method and device and a gun-ball linkage tracking method. The method comprises the steps of acquiring first position information and first feature informationof a first target object in a first image; obtaining second position information and second feature information of a second target object in a second image, wherein the second image is a previous frame image of the first image; calculating the overlap ratio of the first position information and the second position information; calculating the similarity between the first target object and the second target object based on the first feature information and the second feature information; judging whether the first target object and the second target object are the same target or not according to the overlap ratio and the similarity; and when the first target object and the second target object are the same target, determining the first target object as a tracking target. Through the implementation of the invention, the tracking of the target object can be realized without the background construction of the video stream, and the problem that the existing moving target tracking method isdifficult to track the moving target in the video of which the background changes continuously is solved.

Description

technical field [0001] The invention relates to the technical field of video monitoring, in particular to a target tracking method, device and gun-ball linkage tracking method. Background technique [0002] The gun-ball linkage system consists of a bolt and at least one ball camera, wherein the bolt is responsible for capturing moving objects, and then controls the omnidirectional movement of the ball camera and the lens change according to the coordinate position of the moving target in the video collected by the bolt. Magnification and zoom control (Pan / Tilt / Zoom, PTZ), make the speed dome rotate to the picture of the moving target tracked by the trigger, and then the dome will track the moving target in detail. Therefore, the core of the speed dome linkage system lies in the detection and tracking of moving objects. [0003] At present, the moving target detection and tracking algorithm is mainly based on the separation of foreground and background, by comparing the pixe...
