Object tracking is a technique for detecting and following the moving object. It can be used to helping security officers to monitor the room that has a large monitoring working area. The aim of research is to design the visual system of object tracking by using pan and tilt vision system. The orientation of camera can move in vertically and horizontally path. Visualization program for this project is consist of motion detection, edge detection and center of mass. The detected object position can be used for controlling the pan and tilt at mechanical system which is mounted on the camera to track the moving object. The results of research show the design of object tracking can detecting and following walking human with an ideal distance of ...
