Embodiment Construction

[0088] figure 1 Shown is a schematic structural diagram of the moving target tracking method in the present invention, as figure 1 As shown, the moving target tracking method includes:

[0089] Detect the target 10, and segment the moving target area in the video scene from the background;

[0090] Predict the target 20, estimate the next frame motion of the target;

[0091] Match target 30, track matched stable targets, and filter out false targets;

[0092] Update target 40, update the template of the stable target in the current frame.

[0093] First, the first step is to detect the target, that is, to segment the moving target area in the video scene from the background. figure 2 It is a schematic diagram of the framework of the detection target in the present invention, such as figure 2 shown. The schematic diagram of the detection target 10 includes: acquiring video 11: acquiring video content to obtain a scene image, and establishing a background model; preproce...

Abstract

The invention provides a moving object tracking method and a system thereof. The moving object tracking method comprises the following steps: detecting objects, and partitioning a moving object area in a video scene from the background; predicting the objects, and estimating the next frame motion of the objects; matching the objects, tracking the matched stable objects, and filtering the false objects; and updating the objects, and updating templates of the stable objects in the current frame. The method and the system realize accurate tracking of multiple objects under the complex background, and solve the problems of shading, leaf swing and the like; moreover, the operation is simple and convenient, so the method and the system are quite practical.

Description

technical field [0001] The invention relates to video monitoring technology, in particular to a moving target tracking method and system in an intelligent video monitoring system. Background technique [0002] With crime levels and threats increasing, security has become a worldwide concern. Video surveillance is one of the solutions to this problem. In addition to public safety, video surveillance can also effectively solve some other problems, such as the regulation of traffic flow and human flow in crowded cities. Large-scale surveillance systems have been widely used in major places such as airports, banks, highways or city centers for many years. [0003] Because the traditional video surveillance technology is generally manual surveillance, there are many shortcomings such as easy fatigue, easy negligence, slow response speed, and high labor costs. Therefore, in recent years, people have gradually studied a digital, standardized, intelligent and IP networked intelli...
