Paper Abstract

A technique is developed to calibrate a camera which is equipped on mobile robot and detect a distant scene. A flexible calibration target, on which calibration feature points are generated according to cross-ratio invariability, is employed in this paper. As can be extended as needed, the target has a flexible size and can be used at discretionary distance from the camera. To guarantee the generating accuracy of calibration points, coordinates of principal point and radial lens distortion coefficients of first two orders are determined previously. Experiment results revealed the effectiveness of the presented method and higher accuracy than traditional method.
