Research output: Contribution to journalArticlepeer-review


After the advantages and disadvantages of current methods of calibration are analyzed and contrasted, the comparatively widely applied Zhang Zhengyou calibration method is adopted in this paper, but it is used to solve problems in a different way. The calibration of a double-priority camera on the basis of a round planar target is proposed, and a computation method based on the on-line intersection of the two circles with the closest proximity is put forward to fix the center of a circle. This method of calibration is simple and flexible, with good robustness, precision, and practical value.
