Abstract

A new algorithm of camera self-calibration is proposed in this paper according to the situation that the intrinsic camera parameters remain unchanged during the image shooting. The advantage of this algorithm is that it does not need to make any prior assumption for the intrinsic camera parameters. We use conjugate gradient method to estimate the unknown scale factors in Kruppa equations; and then solve Kruppa equations linearly by the estimated scale factors and calibrate the intrinsic camera parameters. The validity of the proposed algorithm has been confirmed by experiments.
