| Abstract: | Digital image corelation(DIC) technique has become one of the most widely used methods for experimental mechanics in recent years.This paper presents a series of novel schemes to enhance the analysis accuracy and speed of DIC.Based on B-spline representation,several recursive interpolation schemes were employed to enhance analysis accuracy as well as computation speed of DIC due to the interpolation algorithm plays an essential role in the DIC measurements.In practice,three-dimensional(3D) measurement is do... |
