Abstract: In order to solve the problem of tracking instability and poor synchronization, the tracking model in orbit object dynamic tracking system is established by using controllable rotating platform, the basic principles of the orbital object tracking is analyzed and the dynamic tracking algorithm is studied; the geometry tracking algorithm of turntable angle and orbit objects synchronous tracking are analyzed in the object motion, the track logic function of corresponding point is derived; the improved PID control algorithm and influence factor ware analyzed. Through the test and analysis, the Mean Shift tracking algorithm is improved, its application in orbit-style dynamic object tracking is analyzed, object retrieval center position is determined by using its nuclear density estimation and tracking image frame image relationship to reach the dynamic object tracking purposes. The results show that the improved method can overcome the instability of unable to synchronize tracking with low contrast and other problem, which is proposed to be feasible in orbit object dynamic tracking system.


Keywords: Object, Control, Tracking, Mean Shift algorithm, Interference.
