IMAGE SPECTRUM TECHNOLOGY-BASED GEOLOGICAL SKETCHING METHOD AND SYSTEM FOR TUNNEL FACE
Document Type and Number:
WIPO Patent Application WO/2024/083261
Kind Code:
A1
Abstract:
Disclosed in the present invention is an image spectrum technology-based geological sketching method and system for a tunnel face. The method comprises: collecting image spectrum data of a tunnel face, and extracting a mineral end member and a spectrum thereof according to spectral information, so as to determine the types and contents of minerals; extracting a texture feature from image information, and extracting a feature waveband spectrum from the spectral information, so as to determine the stratum lithology; extracting a crack feature according to the image information, and identifying a crack filler according to the spectral information, so as to obtain a crack identification result; according to the number and relative areas of cracks, obtaining the degree of crushing of surrounding rocks, analyzing the weathering variation proportion of the minerals according to the stratum lithology and a mineral analysis result for the surrounding rocks, and acquiring the color difference between different degrees of weathering according to a spectral color difference identification result, so as to obtain the degree of weathering of the surrounding rocks; according to the image information, identifying a water outflow form and a water outflow position of a tunnel face to be subjected to detection; and according to the results, performing labeling and summarization by using different labeling symbols, so as to obtain a geological sketch map for the tunnel face. The present invention improves the precision and efficiency of geological logging.
