Panoramic Video Surveillance System

Eye is the most important sense organ for human beings. Among the information people get from sense receptors, more than 70% is from vision. Visions and images are the vivid descriptions of objects. In today's information era, with the rapid development of network, communication and microelectronics technologies, video surveillance system is getting more and more favors from people for its clearness, convenience and abundant content. In the meanwhile, people also put forward more requirements on it.The paper brings forward the idea of Panoramic Video Surveillance System. Using multi cameras monitoring simultaneously, through deep research on image distortion calibration and image stitching, successfully realizes the panoramic images, and finishes the Panoramic Video Surveillance System's initial construction. During the research on image distortion correction, the paper receives a good result on camera calibration by improving the traditional barrel distortion model, and expands the current theories on image distortion correction. The paper also compares and analyses many methods on image stitching, and successfully applies the latest image stitching theory. It provides useful experimental proof for future studies. Panoramic Video Surveillance System can be used in various fields such as videoconference, network shopping and traffic control. It greatly improves the conventional video surveillance system, and has prosperous application future by providing multi-users with flexible operations. At the same time, its simple hardware structure makes the system construction easy and cheap. Therefore the system also has a high economic value. The paper is a successful application of current image distortion correction and image stitching techniques. It also brings forward some new methods on image processing. It is believable that this paper would be a useful guide for future research on these areas.
