Key Techniques of Fast Photographic Geological Logging in Exploration Tunnel

摘要

Because of the special geometric shape and narrow space of exploration tunnel, field geological logging in exploration tunnels has always been staying at manual drafting stage with low efficiency and low level of informatization. This paper studies the existing issues of photographic geological logging in exploration tunnel, including the control method, image acquisition method, geometric correction of original images and the generation of display images, etc. This paper realizes fast acquisition and processing of the image data of geological logging, meeting the accuracy requirement of photographic geological logging in exploration tunnels, filling the vacancy of photographic geological logging technologies in exploration tunnels, improving the efficiency, level of automation and informatization of geological logging in exploration tunnels.
