Abstract

The invention provides a multi-target tracking method and device in video monitoring. The method comprises the steps of: obtaining initial information of at least one interest object in a tracking video, wherein the initial information includes initial positions, speeds, accelerations and characteristic information; according to a sequence from big to small in characteristic saliency, selecting N0(t) interest objects from the interest objects as an initial tracking layer, wherein the N0(t) is determined by speeds and accelerations of interest objects, and the characteristic saliency is determined by the characteristic information; carrying out tracking on the N0(t) interest objects in the initial tracking layer one by one according to the initial positions of the N0(t) interest objects; and according to the correlation degree between untracked interest objects and the integral tracked objects, the untracked interest objects are selected into the next new tracking layer in sequence for tracking layer by layer. By adopting the multi-target tracking method and device in the video monitoring, the effectiveness and the accuracy of multi-target tracking are improved.

Description

technical field [0001] The invention relates to the technical field of video monitoring, in particular to a multi-target tracking method and device in video monitoring. Background technique [0002] In recent years, space-based surveillance systems have been widely used in fields such as field surveys and intelligent transportation, especially in key areas such as road safety and emergency rescue, due to their good mobility and large monitoring range. The system can obtain a large amount of intuitive on-the-spot information in a timely and effective manner, and provides strong technical support for protecting the lives and property of citizens by acquiring and processing the operation status of objects of interest in the tracking scene in real time. [0003] In the space-based surveillance system, as the core of target operating status acquisition, target tracking has always been the research focus of various surveillance technologies. The tracking process of an existing mu...
