摘　　要：Manual operation of gauge calibrator is tedious and time-consuming.The automatic transformation of calibrator is realized through the integration of motion control and machine vision technology.Two closed-loop positioning subsystems are composed of digital caliper length standard,chain drive mechanism and stepping motor to realize automatic motion control of gauge and ultra-high parameter measurement points.According to the luminance,geometric shape structure and fitting feature information,all kinds of indicator features and their relationships are identified in the display dial image to realize machine vision reading.The noise is removed by image difference method,the image is binarized by adaptive iterative threshold method,and the cross section contour of the track is obtained by expansion and thinning algorithm.The experimental results show that this method can effectively realize the high-precision dynamic measurement of gauge parameters.
