Abstract: To calibrate some parameters of the digital camera such as principal point,principal distance and optics distortion ratio for the precision and reliability,a high accurate calibrating field for digital camera is built.Spatial analysis is applies to reduce the ill-conditioned state in the system so as to improve the reliability of the calibrating result of digital camera.
