STUDY ON ROCK MASS JOINT MEASUREMENT BASED ON DIGITAL PHOTOGRAMMETRY

Rock mass joints,a typical sort of structural planes,are widely distributed in the rock mass. So the measurement and investigation on rock mass joints are the foundation for rock mass classification and the determination of physical and mechanical parameters. However,the traditional in-situ investigation using manual measuring tools is inefficient and costly. The digital photogrammetry is applied into rock mass joint measurement to overcome these disadvantages in this paper. Based on principles of digital image processing and the characteristics of images of rock mass joints,an interpretation scheme for images of rock mass joints based on digital photogrammetry is put forward,which includes geometrical transform,image enhancement,intelligent recognition and shape analysis. Of these procedures,the intelligent recognition for rock mass joints is discussed in detail. The feasibility of the interpretation scheme is proved in a typical case of digital image processing of rock mass joints.
