Abstract

The master-slave camera is composed of fish-eye panoramic camera and pan/tilt/zoom (PTZ) camera. The fish-eye panoramic camera is capable of monitoring a wide field of view, whereas the PTZ dome camera has high mobility and zoom ability. In order to achieve precise interaction, a calibration method based on panoramic image mosaic is proposed, which first composes a mosaic image by several PTZ images and then gets the mapping relationships recorded in the look-up table by template matching. So the mapping relationship between the panoramic image and the motion parameter of PTZ camera can be obtained. Experimental results have demonstrated that it can provide an efficient, fast, and automatic method for the calibration of the master-slave camera.
