Multi-target Tracking-based Digital Video Surveillance System

Traditional monitoring system is not good at alarm,so it is hard to be used in the tanglesome places which need to monitor dynamiclly. Because of the surveillance-area of the vidicon, the system will lost the target if it moves out the area in the case of nobody on duty. Digital monitoring system which can track taget automaticlly has much advantage than traditional alarm system, especially in the Place andtime when no one work there. The method used in it which is presented and effective because it can judge whether the invade object is harmful or not.Many valuable new methods and new techniques has been studied in this paper to solve these problems. At first, a double-angle coordinate based by the specification of one view vision is given to fit for tracking. In the motion detection a method which is based on time and space is used for it can detect harmful invade object in spite of surroundings inteferre. In addition, after got the image of objects, the rectangle frame technique is used to fill the hole.In my design another part is multi-objects image tracking which is a new technique and it integrates image processing, automatic control and computer science.This technique can automatically acquire objects from image signal, get objects' position information then track them with the aid of dome.At the end of this thesis is a sofeware design project was discussed based on those theory we talked above which could track objects atuomaticlly.
