Abstract :
A camera self-calibration method based on the two pairs of parallel lines that are orthogonal each other is presented in this paper. The self-calibration can be realized based the fact that the modulus constraint can provide an equation and two equations can be obtained from two pairs of parallel lines that are orthogonal each other. The self-calibration method presented in the paper is quasi-linear. The experiment results show that the presented method is efficient.
