Embodiment 1

[0072] The above is the first embodiment of a target tracking method provided by the embodiment of the present application, and the following is the second embodiment of a target tracking method provided by the embodiment of the present application. In order to facilitate understanding, the second embodiment is based on the first embodiment , taking the target to be detected as a pedestrian as an example, the tracking method in this application is described in detail.

[0073] see figure 2 , figure 2 It is a schematic flowchart of Embodiment 2 of a target tracking method in the embodiment of the present application.

[0074] A target tracking method in this embodiment, the specific method is: when detecting a pedestrian, it will return the coordinates of the top of the head and the frame coordinates of the pedestrian. At this time, the pedestrian is separately cut out according to the frame coordinates (to obtain a picture of the pedestrian), and the picture and the coordin...

Embodiment 3

[0122] The above is the third embodiment of a target tracking method provided by the embodiment of the present application, and the following is the embodiment of a target tracking device provided by the embodiment of the present application.

[0123] see Figure 4 , the target tracking device in this embodiment specifically includes:

[0124] An acquisition unit 401, configured to acquire target information obtained when each camera shoots a target to be detected;

[0125] The selection unit 402 is configured to perform area selection on the captured images corresponding to each camera according to each target information, so as to obtain the image coordinate area of ​​the target to be detected under each camera;

[0126] A conversion unit 403, configured to convert each image coordinate area to the world coordinate system, to obtain the world coordinate area of ​​the target to be detected under each camera;

[0127] A fusion unit 404, configured to fuse all world coordinat...

Abstract

The invention discloses a target tracking method, device and equipment, and a storage medium. The method comprises the steps of obtaining target information obtained when each camera shoots a to-be-detected target; according to the target information, carrying out area selection on shot images corresponding to the cameras, and obtaining image coordinate areas of the to-be-detected target under the cameras; converting each image coordinate area into a world coordinate system to obtain a world coordinate area of the to-be-detected target under each camera; fusing all world coordinate areas corresponding to the to-be-detected target to obtain a target three-dimensional coordinate area corresponding to the to-be-detected target; and tracking the to-be-detected target through a tracker established according to the three-dimensional coordinate area of the target. The technical problem that the target tracking method in the prior art is easy to cause target loss is solved.

Description

technical field [0001] The present application relates to the field of computer vision, and in particular to an object tracking method, device, equipment and storage medium. Background technique [0002] The advancement of computer vision and artificial intelligence technology has driven the rapid development of the security industry. There are more and more cameras, thermal intelligence applications based on cameras are rapidly expanding, and enterprises' demand for intelligent cameras is growing rapidly. Among the many tasks of computer vision, target tracking tasks are widely used in the field of surveillance video, the most common ones are pedestrian tracking, vehicle tracking, etc. [0003] Most of the existing target tracking methods track by polling the depth map of each camera and detecting the position of the target according to the depth change. When a target is tracked by the above-mentioned target tracking method, the phenomenon of target loss is prone to occur....
