Embodiment Construction

[0068] In order to make the above objects, features and advantages of the present invention more comprehensible, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0069] Aiming at the complex scene of environment change, the present invention proposes a moving target detection and tracking method, by combining the two methods of background difference and kernel density estimation difference, the change of the moving target can be accurately detected from the input image; at the same time , the tracking method can perform real-time tracking processing on multiple moving targets. The method for detecting a moving object and the method for tracking a moving object will be described in detail below.

[0070] refer to figure 1 , is a flowchart of a moving object detection method according to an embodiment of the present invention.

Abstract

The invention provides a moving target detecting and tracing method and a system so as to solve the problem in the existing target detecting and tracing method that a plurality of false detection results easily appears when the scene is complex. When detecting a moving target, the method combines the background difference and the nuclear density estimating difference together and then conducts fusion processing to the image obtained by the two detection methods so as to eliminate the detection error of the two foreground images and finally pick up the moving target. Afterwards, the detected moving target is traced. The method and the system provided by the invention can better detect the variation of images under a complex scene with variational environment, thereby improving the accuracy of the detection. Furthermore, the method can handle the tracing problem of a plurality of moving targets simultaneously.

Description

technical field [0001] The invention relates to the technical field of image processing, in particular to a method and system for detecting and tracking a moving target. Background technique [0002] Intelligent video surveillance is based on computer vision technology to analyze the video images in the monitoring scene, extract key information in the scene, and form a monitoring method for corresponding events and alarms. Intelligent video surveillance has a wide range of applications in public safety protection and traffic management Applications. [0003] Intelligent video surveillance systems generally use cameras or network cameras to continuously shoot a certain scene, and then process the collected video streams to detect moving objects, and perform subsequent processing such as classification, tracking, and identification of moving objects. The detection and tracking of moving objects is the basis of intelligent video surveillance, which is of great significance to ...
