Calibration of Binocular Vision Measurement of Large Gear Workpiece Welding

The calibration is difficult to binocular vision measurement.The mathematical model of binocular vision measurement calibration is analysed,and the within parameters and the outside parameters of binocular vision calibration is achieved.The image processing,feature point extraction and calibration method are also expounded for the large gear workpiece welding′s binocular vision calibration process.The experiment shows that the binocular vision measurement calibration program is correct.
