【Abstract】 A two-dimensional image measurement system using digital camera is presented,which puts forward a new approach that removes separately the lineal distortion and non-lineal distortion to meet the requirements of high-precision measurement.Two key techniques in the approach,the method to remove the imaging errors based on calibration technique and the method to raise the measurement precision by means of sub-pixel algorithm,are dwelled on,and the experiment results show that the approach has higher precision.更多还原
