Problems solved by technology

However, in practical applications, the suspected target tracked by the user is often a moving target (such as a person or a vehicle, etc.), and a large number of cameras will be involved. Manual investigation is time-consuming, the use remains unchanged, and error-prone

Embodiment Construction

[0053] Please refer to figure 1 The present invention provides a method for tracking a moving target based on video, which can be applied to user terminal equipment in a video surveillance system, such as a computer installed with monitoring and management software. The video-based mobile target tracking method may include the following steps:

[0054] Step 101 , according to at least two locations that the moving object passes through during its movement, generate a reachable path for the moving object to move from a starting location to an ending location in the at least two locations.

[0055] In this embodiment, when the user needs to perform video tracking on the moving object, at least two positions passed by the moving object during the moving process may be first input on the user terminal device. Specifically, the user can select the at least two positions in the GIS (Geographic Information System, Geographic Information System) map, and specify the starting position...

Abstract

The invention provides a video-based moving target tracking method and device. The method includes: according to at least two positions that the mobile target passes through during the movement process, generating an accessible path for the mobile target to move from a start position to an end position in the at least two positions; Whether there is an intersection between the viewing area of ​​the camera and the reachable path; if there is an intersection between the viewing area of ​​the camera and the reachable path, the collision factor value of the camera is calculated; according to the collision factor value of the The cameras are sorted by size to generate a camera list, so as to track the moving target according to the video captured by the cameras in the camera list. Through the technical solution of the present invention, the list of cameras photographed by moving targets can be automatically screened out without manual checking one by one, and the efficiency of video tracking is improved. At the same time, the user operation is very simple, and the user can obtain a very good experience.

Description

technical field [0001] The invention relates to the technical field of video monitoring, in particular to a video-based moving target tracking method and device. Background technique [0002] Video surveillance is an important part of the security protection system. It is a comprehensive system with strong prevention capabilities. Video surveillance is widely used in many occasions because of its intuition, accuracy, timeliness and rich information content. [0003] In many application scenarios, such as when a crime occurs, the user needs to check the video recordings captured by the cameras around the incident location one by one to find the suspect. However, in practical applications, the suspected target tracked by the user is often a moving target (such as a person or a vehicle, etc.), and a large number of cameras will be involved. Manual investigation is time-consuming, unchanged in use, and error-prone. Contents of the invention [0004] In view of this, the prese...
