摘要：A high precision and easy-to-use CCD camera calibration technique for industrial vision metrology is discussed. A well-known method is self-calibration by convergent camera configuration of a two- or three-dimensional target field. Only with this technique the central part of a sensor area is precisely calibrated, but off the centre the precision rapidly deteriorates. The presented technique is a simultaneous adjustment of both pan and close exposures, which compensates the lack of distortion data in the fringe area of the sensor and offers both uniform and high-precision calibration. Some patterns of camera configuration are compared in an experiment in terms of the precision and its uniformity over the sensor. And the combination of convergent pan exposures and vertical close exposures is proved the best
