Embodiment Construction

[0023] A multi-dome camera linkage target tracking method based on the improved Meanshift algorithm, the method includes the following steps: (1) Obtain the initial image sequence in the dome camera monitoring scene, and use background subtraction to analyze and process the initial image sequence to obtain The initial position and size of the moving target; (2) use the improved Meanshift algorithm to track the detected moving target; (3) use the fuzzy control method to control the rotation of the ball machine, so that the moving target is roughly kept in the center of the ball machine; (4) When the moving target enters the public monitoring area of ​​multiple speed domes, the multiple speed domes enter the state of detection and tracking. If the moving target leaves the public monitoring area and enters the field of view of a certain speed dome, start the corresponding speed dome and return to step (1) Track moving objects, such as figure 1 , 2 shown.

Abstract

The invention relates to a multi-ball machine linkage target tracking method based on an improved Meanshift algorithm. The method comprises the following steps of: obtaining an initial image sequence in a ball machine monitoring scene, and analyzing to obtain a moving target; tracking the detected moving target; controlling the ball machine to rotate by use of a fuzzy control method so that the moving target is approximately kept in the central range of the ball machine, wherein when the moving target enters the public monitoring area of multiple ball machines, multiple ball machines enter a detection to-track state; and if the moving target leaves the public monitoring area and enters the visual field of a ball machine, starting corresponding ball machine, and returning to the first step to track the moving target. The invention also discloses a multi-ball machine linkage target tracking system based on the improved Meanshift algorithm. According to the invention, the linkage target tracking of multiple ball machines is realized through the detection, real-time tracking and fuzzy control of the moving target, the robustness is greatly improved, and the monitoring range is expanded.

Description

[0001] technical field [0002] The invention relates to the field of intelligent video monitoring, in particular to an improved Meanshift algorithm-based multi-dome linkage target tracking method and system. Background technique [0003] With the development of the national economy and the acceleration of economic globalization, the security industry is developing rapidly. Every city has tens of thousands of cameras. Accurately searching relevant information from video storage resources and enabling video surveillance equipment to accurately track suspects has become a difficult problem for public security personnel. With the application of computer vision and digital image processing technology in target tracking, intelligent video surveillance technology (IVT Intelligent Video Technology) also came into being. IVT is to replace the brain with a computer and the eyes with a camera, and the computer intelligently analyzes the image sequence captured by the camera to unders...
