Abstract
In this paper we proposed a novel stereo rectification method for dual-PTZ-camera system, which is called spherical rectification. This method can be divided into two parts, offline pre-settings and online rectification. The offline pre-settings include camera calibration and building the spherical coordinate system. The online rectification only requires the pan, tilt and zoom values and does not need any image information such as feature points. So, compared with traditional rectification approaches, our method is more convenient and time-saving.
