| 摘 要： | 在隧道施工过程中，为了解开挖方量以及隧道前方的地质构造等信息，有必要对掌子面图像进行分析。传统分析中大多数以人工素描为主，效果因人而异。为了克服传统方法的局限，将图形、图像处理及三维建模技术引入对掌子面图像的处理中，建立隧道掌子面地质图像画像系统，对一系列跟踪拍摄的掌子面图像进行处理，自动提取出掌子面上不同岩层的边界，获取岩层的特征信息，以此对围岩分级。根据相邻掌子面上岩层目标的对应关系，建立起隧道的三维模型，为隧道施工提供必要的参考信息。

| 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. |
