【 摘 要 】

On the basis of using the vacuum epoxy impregnation technology to obtain microscopic images of building materials, algorithms such as image scaling, index image, image recognition and image identification are respectively designed to identify the pores of the building materials through programs. The images zooming adopts bilinear interpolation to realize the lossless compression of the original microscopic image. The identification of the aperture adopts the method of brightness screening, and the operation of morphological opening and filling. Through the identification of the pores, the material defects can be further analyzed by mesomechanics.
