This design compares three models for determining the internal and external parameters of a digital camera, included the model of considering the horizontal and vertical correction, the model of adding affinity deformation, the model of Luca Lucchese. In this paper, the work is that judging three models by the distortion coefficient, residuary distortion, the accuracy of examining spots .The results of the experiment suggest that the method of considering the horizontal and vertical correction has the better stabilization and veracity of distortion calibration. This model can still calibration the ordinary digital camera images well on the condition of only a little points for controlling, so it has the better usefulness in the practice |
