Paper Abstract

In this paper, a practical approach of the calibration of a stereovision system is proposed. At first, the internal parameters are calibrated with the traditional method. Then, after the two cameras are mounted, relative position of the two cameras is determined by solving the essential matrix. Thus, elaborate setup of the control points is avoided, which allows the method be applied outside laboratory environments. Additionally, a new solution of the essential matrix is described, which is easier to be comprehended and implemented. Chessboard-like patterns are used in the calibration and the grid corners are detected automatically by a new scheme based on the symmetry in the local area. Experiments have been carried out to test the approach. Results achieved by the proposed approach are as accurate as those achieved by the traditional methods.
