Tunnel surrounding rock deformation detection method adopting digital camera technique

The invention discloses a tunnel surrounding rock deformation detection method adopting a digital camera technique under the remote control of a computer. The method is characterized by arranging a plurality of observation points on the section of the tunnel surrounding rock, shooting the observation points by utilizing digital imaging equipment, transmitting the acquired images to a monitoring computer by utilizing a wireless network and processing the monitored images by the monitoring computer to obtain the measurement data of surrounding rock deformation. The method has the following advantages: by shooting the plurality of observation points on the section of the tunnel surrounding rock, utilizing research methods such as image enhancement, image pre-processing, image recognition and the like and adopting multistage image processing, the contrast is improved, the target margin is sharpened, and the observation points on the surrounding rock become clearer, thus effectively separating the key recognized targets from the tunnel background and then carrying out coordinate positioning and contrast on the processed images; and measurement and early warning can be carried out on surrounding rock deformation quickly, safely and automatically.
