Abstract

The embodiment of the invention discloses a multi-target tracking method and device, an electronic device and a storage medium. According to the technical scheme, the method comprises: detecting a target and a corresponding position through the target detection model; allocating a target tracker to each target, predicting the position of each target in the next frame of image through a target tracker; matching the detection position of each target with the prediction position of the next frame of image through Hungary; obtaining a tracking segment corresponding to each target; obtaining a tracking chain of each target by combining tracking fragments corresponding to each group of adjacent frame images; and finally, according to the tracking chain, the position of the target exceeding or returning to the target tracking area to serve as a settlement or refund basis of the corresponding commodity, completing dynamic tracking recognition of multiple targets. Missing detection and false detection are avoided, the target recognition precision is improved, and the settlement process of the user is further simplified.

Description

technical field [0001] The embodiments of the present application relate to the technical field of image recognition processing, and in particular to a multi-target tracking method, device, electronic equipment, and storage medium. Background technique [0002] At present, in the field of smart retail and unmanned retail applications, unmanned containers and smart containers are the main application products in this field. The use of unmanned containers simplifies the settlement process of commodities, and the rapid identification of commodities can save users' waiting time and greatly save labor costs. Moreover, unmanned and rapid identification can improve the customer experience. The main recognition technology of the traditional unmanned container is based on static product detection. When identifying the product, it needs to send the product into a fixed camera shooting area, or the product in the container under the fixed detection shooting area. When the camera is tr...
