Problems solved by technology

[0004] The purpose of the present invention is to provide a system and method for automatic video tracking of personnel's action trajectory to solve the existing problems: in the prior art, a pan-tilt camera must be used, which has high requirements for the camera and is easily affected by light, interference and other objects. Influenced by environmental factors, the tracking effect is not good, and in the multi-person tracking scene, it is necessary to use multiple PTZ cameras to work at the same time, because the division of labor between the cameras is not clear, it is impossible to achieve a good automatic tracking effect

Abstract

The invention discloses a system and a method for automatically tracking the action track of a person through a video, and relates to the technical field of automatic video tracking. The system comprises a personnel positioning signal transmitting device, a personnel positioning signal receiving device, a plurality of image display devices and a plurality of cameras, wherein the cameras are used for monitoring corresponding monitoring areas, storing the monitoring areas as videos and sending the videos to the image display equipment; the personnel positioning signal transmitting equipment is used for determining coordinate information of personnel and transmitting a positioning signal; the personnel positioning signal receiving device is used for receiving a positioning signal. According to the invention, video linkage tracking can be carried out based on accurate positioning information of personnel through cooperation of each device, a good automatic tracking effect is achieved, the video camera has clear division of labor, video tracking in a multi-person scene is more accurate, the camera can be effectively prevented from being influenced by environment factors such as scene light and interferents, and the requirement on the monitoring camera is low.

Description

technical field [0001] The invention belongs to the technical field of automatic video tracking, and in particular relates to a system and method for automatic video tracking of human action tracks. Background technique [0002] In the prior art, cameras with pan-tilt function are usually used when tracking people’s movement trajectories. By adjusting the shooting direction and angle of the camera to track people, the pan-tilt camera supports adjusting the direction and angle of the camera lens; through software algorithms, the camera itself analyzes the current captured image According to the movement of personnel, it can independently adjust the shooting direction and angle of its lens to ensure that the personnel are in the picture, so as to realize the tracking of personnel; [0003] However, in the existing technology, a pan-tilt camera must be used, which has high requirements for the camera, and is easily affected by other environmental factors such as light and inter...
