COM Component Based on Matlab Algorithm for Speckle Processing
As a non-contract optical measurement method in solid mechanics,the digital speckle correlation method (DSCM) has already been recognized as an excellent method for determining the surface deformation field in materials because of its outstanding features.In-plane displacement fields at the surface of objects under load are abstracted by using this method in this paper.And the corresponding maps of displacement fields are drawn to show deformation.The basic principle and mathematical model of gradient-based subpixel registration are briefly introduced for measuring subpixel displacement.COM component of this method is generated by using matlab7.1 through images of laser speckles.The COM component is called by Visual C++6.0 and the stand-alone application is generated.It is becoming easier to deal with image in Visual C++ by using this method.Then more time and energy will be spent on the algorithm.The development cycle of the algorithm is speeded up and efficiency of the application is improved.
