Embodiment Construction

[0064] In order to make the objectives, technical solutions and advantages of the present invention clearer, the present invention will be described in further detail below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. . Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0065] The following is an explanation of some words that appear in the text:

[0066] 1. The term "and / or" in the embodiment of the present invention describes the association relationship of the associated objects, indicating that there can be three kinds of relationships, for example, A and / or B, which can mean that A exists alone, A and B exist at the same time, independently There are three cases of B. The character "...

Abstract

The invention provides a multi-target tracking method, which is used for solving the technical problems of uncontrollable multi-model calling efficiency, low feature extraction and recognition efficiency, easy target loss and low target tracking accuracy in the prior art, and comprises the following steps: obtaining a first video frame and a second video frame, the second video frame is a previous video frame adjacent to the first video frame; respectively processing the first video frame and the second video frame through a target detection network, determining a plurality of first targets in the first video frame and a plurality of second targets in the second video frame, and obtaining pose information corresponding to each first target and each second target; respectively calculating predicted pose information of each second target in the first video frame according to the pose information corresponding to the plurality of second targets; and performing target matching based on the predicted pose information and the pose information corresponding to the plurality of first targets, and performing tracking according to a target matching result.

Description

technical field [0001] The present invention relates to the technical fields of video image processing, computer vision and the like, and in particular to a multi-target tracking method, device, equipment and medium. Background technique [0002] Sorting algorithm (Simple Online And Realtime Tracking, Sort) algorithm is a traditional online realtime tracking algorithm, which decomposes the multi-target tracking problem into target detection, state prediction and data association. The detection part of the Sort algorithm usually adopts the fast transfer learning target detection algorithm (Faster-Region-CNN, Faster-RCNN). However, it does not take into account that the appearance features of each target are only matched using IntersecTIon over Union (IOU), which will lead to the phenomenon of id tag switching often occurring in actual use, and the lost target can no longer be used. get back. [0003] In the prior art, in order to solve the above problems, there are the foll...
