Research on Digital Mine Photographic Surveying Information System

This thesis utilizing photographic surveying principle and using a digital camera to shoot and monitor the mine surface, quick-get mine spatial data, formed large scale shadowgraph. Measuring changes of the earth's surface and underground mining condition, meanwhile, it detect the rationality position of the blasting hole using the shooting video mine, and make adjustments based on these data. Using the computer C language, according to digital photography measuring theory, a real-time and quick-get digital mine information system is built, and this provides powerful tools for timely getting mine dynamic information.
