The Application of Digital Photogrammetry in Digital Information of Mine

Abstract

This paper utilizes photographic surveying principle and uses digital camera to shoot and monitor the mine surface, and quickly collect mine spatial data. Based on the data, a 3D model of mine surface is built. The large scale maps of mine are made. Based on coordinates and 3D model in the period of different time, changes of mine surface are get obtained. The 3D model can help to get the shape of mine in time and test mine exploration and make adjustments based on the data.
