Multi-image Vanishing Point Based Camera Calibration

Abstract

In the past decades, there are many researches relating to 3D object model building in the fields of computer vision and photogrammetry, and camera calibration is one of most important hot topics among those. In this paper, we first reviewed the theory and its applications on camera calibration with vanishing points. Furthermore, a novel approach to camera calibration by multiimage vanishing points is proposed. This approach overcame the demerit of the theory based on single image; the accuracy of interior and exterior orientation parameters calibrated became better and more stable.
