Abstract

According to the depth estimation, the calibration technology of zooming cameras, which combines the general method of camera calibration with characteristics of zooming cameras, is researched in this paper. By the least squares method, two coordinates of shrink-amplify center which have been generated under two different focal length are calibrated and analyzed. Thus, the foundation of depth estimation for zooming image would be laid. The experimental results show that the depth estimation can be done by shrink-amplify center which replaces the principal point and the coordinate of shrink-amplify center has good stability after calibrated many times.
