一种新的基于灭点的相机标定方法

New method of camera calibration with vanishing points

对基于单像的灭点相机定标的理论进行了详细的阐述,并在此基础上提出了一种新的基于多方位、多像的灭点标定方法.这种方法克服了原有理论的缺陷,可对相机的内外方位元素以及畸变差联合求解,使标定结果更加精确、稳定.

By discussing the theory on camera calibration with vanishing points and analysing the errors resulted from calibration based on vanishing points, a novel approach to camera calibration by vanishing points in multi images is proposed to acquire orientation parameters, even radial lens distortion and thereby to improve the precision of interior and exterior orientation parameters.
