A camera calibration method based on two orthogonal vanishing points

摘要

A camera calibration method based on the two vanishing points, which are orthogonal to each other, isrnpresented in this paper. On the basis of the facts that the modulus constraint can provide an equationrnand that two equations can be obtained from two pairs of vanishing points, which are orthogonal torneach other, the self-calibration is quasilinearly realized. The experiment results with simulate datarnand real image sequences show that the presented method is efficient.
