Abstract

In this work, an automatical camera calibration method based on coded ring markers is proposed, which is easy to operate and greatly improve automaticity of camera calibration. In this method, we firstly describe a calibration target, which consists of three coded ring markers and a planar pattern. In calibration, the ring markers are recognized and decoded, and then the center coordinates are sorted according to the coded values of the markers. Finally, the intrinsic parameters of the camera can be obtained with these sorted markers. Experimental results demonstrate the accuracy of the method.
