数字散斑相关方法;应用数字图像相关法计算变形前后图像中各点的位移量时,先通过整像素搜索法来确定各点的整像素位移,进而根据整像素搜索得到的相关系数值来计算各点的亚像素位移.提出了一种新的整像素搜索法,即采用计算窗口加权的方法对变形前后图像中的点进行搜索计算 XTDIC...
The Digital Image Correlation (DIC) method is commonly used in fracture analysis, but it has limitations in measuring discontinuities, which is crucial in fracture analysis. To address this issue, this paper proposes the Adaptive Discontinuous Digital Image Correlation (AD-DIC) method, which is expl...
计算窗口加权因子In the digital image correlation method,the first step to obtain the displacements of each point in the images taken before and after deformation was to confirm its integer pixel displacement,then to compute its sub-pixel displacement using the correlation coefficient of the integer ...
