A Research Of Moving Target Intelligent Surveillance System With Dual Fields

Intelligent surveillance technology is one of the main content in the field of computer vision.With the continuous improvement of people's requirements for life quality,the traditional surveillance system has been unable to meet people's application needs.In order to solve the problems of the traditional surveillance system,such as the limited image resolution and a large amount of redundant data,a moving target intelligent surveillance system with dual fields is proposed in this paper.The wide field camera is responsible for the overall monitoring of a wide range of vision and the scheduling of the narrow field camera to track the specified moving target.The narrow field camera is responsible for obtaining high resolution target image.The main work of this paper is summarized as follows:(1)Different from the traditional multi-camera system,this paper classifies the camera of the surveillance system.Under the premise of controlling the amount of redundant data,this paper not only realizes the wide range of overall monitoring but also gets the detail information of the moving target by replacing the video sequence with the high resolution moving target image.(2)Research on image correction algorithm,moving target detection algorithm,moving target tracking algorithm and object hand-off algorithm.Focus on the camera calibration technology,the background difference method using different background model,color matching,different color space characteristics,corner point detection algorithm based on SURF(Speeded Up Robust features)algorithm and ORB(Oriented FAST and Rotated BRIEF)algorithm.(3)Improve the background difference method based on the concept of information entropy.The improved algorithm takes into account both the computational speed and the detection accuracy.(4)Propose an algorithm of moving object matching for the application of this paper,which is based on corner feature and color feature.(5)Realize video capture module,image correction module,moving target detection module,object hand-off module,PTZ(Pan-Tilt-Zoom)camera control module and moving target active tracking module,using C++ language on VS2010(Microsoft Visual Studio 2010)platform.
