Abstract: Through the use of the image of a gray scale gradient to calculate the threedimensional displacement field distribution, the research improves the accuracy and efficiency of the displacement using ternary cubic interpolation gray of sub-voxel location. Based on the results of simulation analysis, this paper has verified the correctness of the method.

Key words: deformation field; digital volume image correlation; tricubic interpolation
