Abstract: Aiming at the shortage of hydroelectric engineering geological logging methods on high side slope and big gallery, the photographic methods based on digital camera were studied. By integrating the application of technology of close range photogrammetry, digital image processing and GIS, the photographic geological logging information system was developed. The system has the functions of digital photography, orthophotoquad making, image mosaicking, logging factors extracting and measuring, CAD mapping, etc. The methods achieve more efficient and higher precision than the regular, and it provides a new way for the hydroelectric engineering geologic logging.
