Abstract Based on the analysis of the advantages and disadvantages of the traditional omnipotence tool-microscope and modern digital equipment,a new measurement based on image processing is presented.This method combines image measurement technology with grating measurement technology based on FPGA and SCM,and uses AutoCAD secondary development of technology for length,angle,diameter,and other geometric precision measurement of the amount.On the basis of maintained advantages of original equipment such as high precision,strong anti-jamming,long-term stability,wide application and so on,it can improve efficiency and precision of measurement and reduces operation intensity.Compared with the test results of Dual-frequency laser interferometer,it proves that this method has high precision repeatability and measurement accuracy.
