Photogrammetry technology has been widely used to determine the ground motion study of land subsidence in the mine, and ground photogrammetry techniques have been used to monitor the project structure. The main advantage of using photogrammetry is to reduce the time of the field survey; while the three-dimensional coordinates; you can monitor an unlimited number of points on principle. In recent years, photographic measurement point position determination accuracy is greatly improved, which makes it attractive for high-precision measurement of the deformation
