Abstract

Abstract:

An improved method about the camera calibration method based on circular points was proposed, by which one can solve intrinsic parameters lin
early under the conditions of no demand of any physics measurements and matching between model plane and image. Furthermore, we proposed a new nonlinear solution for extrinsic parameters under the condition of no more other known information. Experiment results show that the method proposed is more accurate and robust.

Key words: camera calibration, circular points, tangency point invariance
