一种用于松质骨变形测量的数字图像相关方法
A DIGITAL IMAGE CORRELATION METHOD FOR DEFORMATION MEASUREMENT OF CANCELLOUS BONE
摘要
Abstract
Aimed at the porous materials such as cancellous bone, directly using the measured object's own micro-structure or texture instead of artificial speckle markers, and then use Matlab to prepare the deformation measurement calculation program, and try to apply the digital image correlation(DIC) method to the measurement of cancellous bone deformation.Generating the simulated speckle image to simulate the feasibility of the algorithm, and the whole deformation measurement scheme is validated by using the compression test piece made of porcine femur.The results of simulation and experiment show that it is feasible to use the microstructure texture of the cancellous bone as the mark and use the algorithm program to carry out DIC deformation measurement.The protocol can also be used for deformation measurement of other porous materials having similar microstructures to cancellous bone.关键词
