Title Application of digital close-range photogrammetry in rock engineering
Abstract Fractures of rock mass structural plane are necessary for any one rock mass engineering study, so it is particularly important to fully understand the distribution of structure plane of the rock mass in engineering practice. With the development of computer and measurement technology and the needs of modern construction, measurement techniques based on digital close range photogrammetry which could fast collect the information of rock mass structure plane provides a new approach to collecting information of rock mass structural plane, and shows a broad application prospects. The purpose of this thesis is to master the methods of structural plane photogrammetry, and makes a systematic analyze of the parameters of rock mass structural plane by using of images and information of measurement. This thesis first introduces the definition and development of the digital close-range photogrammetry and the role of research in rock mass structural plane. and make a full summary of the digital close-range photography measurement technology; And then this thesis states systematically the principle and method of the digital close-range photogrammetry technology, mainly including the close-range photogrammetry theory, photography requirements, acquisition of control-point coordinates , principle of feature matching, and interpretation of the rock mass structural plane fracture parameter. Finally, based on an application example this thesis details the calculation process of digital close-range photogrammetry in the rock mass structural plane information acquisition. Through and analysis, it finally obtains the structure fracture traces diagram below, but the experimental method and precision of data remain to be improved .
