The digital image processing techniques, including gray level transformation, image sharpening, image segmentation and edge detection, is applied to the study on the meso-structure image of shale. The results show that the digital image processing technique can extract useful information from the CT images and construct a model of meso-structure of shale. The model shows the spatial distribution of the different media in the rock. The process of the damage propagation can be seen IN the meso-structure image clearly. Meanwhile, a process, including geometrical vectorization, scaling transformation, and the realization of the FEM software interface, is provided to establish a finite element grid model. The proposed approach can be a research foundation for the further study on the physical and mechanical properties of rock.
