Correction of the Deformation Measurement Method Using Target Marker Image in Geotechnical Centrifugal Imitation Test

The research aims at the distortion of target marker deformation image in geotechnical centrifugal imitation test.Based on the basic principle of marked point‘s deformation measurement method and the reason of image distortion, this paper puts forward and completes the distortional image correction using space vector and coordinate transformation method.When the target marker deformation image is corrected it can achieve the desired well correction effect and purpose.The correction of target marker deformation image is one of the effective way to improve the accuracy of the test results.
