Abstract: According to the defects of tracking moving object by PTZ camera,such as relying on manual operation,unreal-time and uncontinuous tracking,almost leading to the failture of tracking,a new intelligent control system was designed by using HSV color histogram as model feature.Then Camshift algorithm was adopted to realize object tracking location and Kalman filter model was adopted to estimate the moving object location of the next time.Finally closed loop idea was used to controll PTZ camera platform movement and lens antomatic zoom.The new system improves the real-time performance.Cooperating with the intelligent control system,the effect of tracking is more accurate by controlling the PTZ camera with Android smart phone.The results show that the method is feasible,has the advantages of simple control and remaining correct location,and it also can improve real-time performance and reliability of object tracking.
