Abstract

The tracking system usually has some lack of problem, that is unstable system when the object moved so the tracking process can’t define the object position well. On the other hands, when the object moves, the system can’t track object suddenly along to the direction of objects movement. The system will always looking for the object from the first point or its home position. In this paper, PID control was used to improve the stability of tracking system, so that the result became more stable than before, it can be seen from errorof tracking. Otherwise, to looking for again the undetected object, a linier regression method was used in purpose to get more faster in finding the new position of a movement object that was disappear from the views of camera before . When the object on unmoved condition, the system has error value ±15 pixel. For horizontal move condition of servo on slow motion ±9.4 pixel, also on the fast motion, the error values is about ±20.1 pixel. For the servo with vertical movement ,the error value is about ±13.4 pixel for the slow motion and ±45.7 pixel for fast motion. The process on finding the object that was disappear from the views of camera before, ±2 second. Finally it can be concluded that the add of PID control and linear regression method, make the tracking system become more stabile and real time.
