Computer vision has the advantages of low-cost, non-contact, as well ashigh-precision. So it is widely used in industrial measurement, video monitoring,medical imaging, and other areas. However, the accuracy of computer visionmeasurement system largely depends on the camera calibration accuracy. Therefore,the research on the methods of camera calibration has become one of the hot fields in theworld in recent years. In order to improve the calibration accuracy, the parameters of thetraditional camera calibra...
