Abstract: During tunneling, geological logging and rock mass classification are two major tasks to be concerned, so tunnel driving face image analysis is essential. Traditional analysis is time-consuming, costly and the effect is different with different operators. While conventional approaches are limited, graph and image processing and 3D modeling technology were adopted for tunnel driving face imaging. Tunnel driving face geology image system (TFGIS) was designed to manipulate tunnel driving face, so that rock edges and rock characteristic information can be acquired, by which rock mass was classified. After processing a series of driving face images which were snapped by tracking when tunneling and marking corresponding rocks between two adjacent driving face images, according to rock corresponding relation, 3D tunnel model was built up, which can be regarded as reference information for tunneling.

Key words: image processing, 3D modeling, tunnel driving face
