Embodiment Construction

[0045] As described in the background technology, although the existing technology is dealing with the tracking problem in the hyperspace, it uses multiple cameras based on the positioning information of multiple selected height layers, and uses the shortest path algorithm to process the positioning information of each layer to obtain multiple Layer tracking trajectory, combined with the processing results of foreground extraction, completes the stereo tracking of multiple targets. However, when dealing with multiple targets intersecting and occluding each other, it will still cause tracking ID confusion.

[0046]In view of the above problems, an embodiment of the present invention provides a cross-scenario multi-target real-time tracking method, which is applied to a basic spatial layout composed of multiple storage structures and passage structures in large venues. The technical solutions in the present invention will be clearly and completely described below in conjunction ...

Abstract

The invention discloses a video target tracking method and device. The method and device divide the target candidate area into a plurality of grids of the same size by setting the intermediate channel area as the target candidate area, and obtain the current frame of the target to be tracked. At the same time, according to the identification features of the target to be tracked in the previous frame of the current frame and the corresponding grid position, and the identification features of the target to be tracked in the current frame and the corresponding grid position position, determine the position information of the to-be-tracked target, and then track each of the to-be-tracked targets in the monitoring unit area. By applying the technical solution of the present application, it is possible to continuously perform accurate video tracking on a target in a large-scale area, which greatly improves the efficiency and accuracy of continuous monitoring and tracking.

Description

technical field [0001] The invention relates to the technical field of video tracking, in particular to a video object tracking method and device. Background technique [0002] In recent years, artificial intelligence technology has gradually entered people's lives from the laboratory level, and smart new retail is undoubtedly a representative of it. As a type of smart new retail, unmanned supermarkets integrate technologies such as computer vision, sensors, and deep learning. When a product is taken away from the shelf by the user, the sales management system can automatically detect it, and the user can leave directly after completing shopping. You don't need to queue up to check out, and you will receive the bill on your mobile phone. [0003] The inventor found through research on the prior art that most of the solutions for unmanned supermarkets currently focus on the identification of goods status and pedestrian status. Among them, the key point of the cargo side is ...
