Abstract:
Video surveillance becomes more and more extended in industry and often involves automatic calibration system to remain efficient. In this paper, a video-surveillance system is presented that uses stationary-dynamic camera devices. The static camera is used to monitor a global scene. When it detects a moving object, the dynamic camera is controlled to be centered on this object. We describe a method of camera-to-camera calibration in order to command the dynamic camera. This method allows to take into account the intrinsic camera parameters, the 3D scene geometry and the fact that the mechanism of inexpensive dynamic camera does not fit the classical geometrical model. Finally, some experimental results attest the accuracy of the proposed solution.
