Abstract

The camera calibration with traditional methods is of low efficiency and big error, and it needs to extract boundary points manually. In order to improve the efficiency and automaticity degree of the camera calibration, a fast and easy method research of automatic camera calibration was presented. In this paper, we designed a home-made filled circular maker box with rectangle border to segment and draw the circles from the complex background automatically, also with three circles of different radius to confirm the boundary and origin. And the detected the edge of the target circles by canny algorithm, and employed the least square method to match the center. Finally ranked the center dot matrix to match the 3D coordinate based the principle of cross ratio invariability, and then provided the results as the input of the Zhang's coplanar calibration algorithm to realize the camera calibration. Experiments show that this method is of higher accuracy and efficiency, and is of stronger practical value.
