Object visual tracking and servo is a challenging research topic in the fields of computer vision, pattern recognition and robotics. Usually, people just utilize PTZ for active surveillance tracking. In this work, we combine visual tracking and visual servo to drive a PTZ to cast laser beam on the target object. The demonstrated tracking system is friendly-using and accurate which can be used for object tracking in plane, such as stage lighting effect, video surveillance, etc. Our proposed tracking system features arbitrarily installation, automatic parameters calibration, high efficiency and low coupling. From the point of mathematical modeling, our model outputs exact solution without any accuracy loss.
