High Accuracy Tracking with an Active Pan-Tilt-Zoom Camera

摘要

Traditional PTZ tracking system focus on tracking algorithm, but PTZ camera control is not taken seriously and the control method has the large deviations. The algorithm for PTZ camera control is defined according to the target position which is achieved by the tracking algorithm in the image, calculates the rotation angles of the two motors to control the PTZ camera. As a result, the target appears in the centre of the image. This paper proposes a model-based algorithm for PTZ camera control, taking into account the camera distortion and the deviation is within 5 pixels. Experimental results show that the algorithm can be effectively applied to PTZ tracking system.
