The effect of image correction on digital speckle correlation method (DSCM) is researched. And the error caused by differences in attitude is analyzed. Then the theoretical model of image correction based on coding assistance is established. According to the model, computer simulation is conducted. The error of corrected image is significantly reduced after correlation calculation. The relationship between the angle of distortion and matching rate is studied in physical experiment, the error isdoi:10.2991/ismems-16.2016.20 fatcat:ik7ssqk2t5g3pik2t45u4v56ze
