The laser length measurement image method is an effective way to improve the precision of line measure-ment and realize the rapid and direct measurement of line measurement.Aiming at the problems of the wear and de-fect of the line engraving and the inapplication of the traditional image measurement technology,this paper presents a floating table positioning of the loading image measuring mechanism driven by a stepping motor,and realizes the fine tuning function of the mechanism by using the jet technology,the reducer and the lead screw.At the same time,in order to improve the accuracy of the detection device,the positioning error of the laser length measurement is linearly compensated,and the accuracy of the detection device is increased by more than 50％.
