DESIGN AND IMPLEMENTATION OF VIDEO TRACKING SYSTEM BASE ON CAMERA FIELD OF VIEW (CFOV)

Abstract

The basic idea of this project is to design and implement video tracking system based on camera field of view (CFOV), Otsu’s method was used to detect targets such as vehicles and people. Whereas most algorithms were spooned a lot of time to execute the process, we have developed the algorithms to achieve it in a little time. The histogram projection and adaptive gate templatematching (AGTM) was used in both directional to get thetarget from search region, which is robust to various light conditions in CCD images and saves computation time. Our algorithms based on background subtraction, motiondetection and normalize cross correlation operation from a series of sequential images can estimate the motionvector. Camera field of view (CFOV) was determined and calibrated to find the relation between real distance andimage distance.The digital signal processor board (DSP F1228) was designed to achieve the algorithm of controller. Also the system was interfaced with computer through serial port RS232, the three byte protocol was used to transfercommand via RS232 to system. The system has tow degrees of freedom so U-shape platform was designed to mount the CCD camera and stepper motor. The system was tested by measuring the real position of object in the lab and compares it with the result of computed one. So these results are promising to develop the system in future.
