中文摘要： 结构面的空间展布及组合特征决定了岩体的工程地质性质和力学性状，也是构成各类岩体工程地质问题的重要控制因素。由于天然露头或人工开挖面的局限性，难以对岩体结构的几何特征进行系统而确定性的测量，导致对其性状的准确描述极为困难。本项目基于地面型三维激光扫描技术，结合其精度高、速度快、无接触测量、逼近原型的特点，研究岩体三维点云数据的结构面出露迹线准确识别与提取方法，深入分析岩体结构面空间展布特征的拟合计算数值模型，开发点云数据中结构面产状计算相关程序，探讨岩体结构面迹线自动追踪、识别技术，尝试结构面产状的识别与统计分析的程序自动化开发，实现地质结构面快速编录成图及性状补充描述等内容，建立一套基于三维激光扫描技术的岩体结构快速辅助地质编录的理论与技术方法。

英文摘要： The spatial distribution and composing characteristics of the surface structure determine the engineering geological properties of the rock mass and mechanical traits, and they also constitute the important controlling factors of all kinds of rock engineering geological problems. Due to the limitations of natural outcrop or artificial excavation surface, it is difficult to systematically measure the geometric characteristics of the rock mass structure with certainty, which leads to the difficulty in accurately describing its traits. Based on the terrestrial 3D laser scanning technology and combined with its characteristics of high accuracy, speed, non-contact measurement and closing to the prototype, the project is aimed to study the accurate identification of structure surface's outcrop trace and the extraction methods of the rock mass's 3D point cloud data, to deeply analyze the numerical model for calculating fitting of rock mass's structural spatial distribution characteristics, to develop the related procedures of calculating the structural plane program development in the point cloud data, to probe into the rock structure plane's automatically tracing and the track recognition technology. Moreover, the project tries to identify the structure surface occurrences and automatically develop the program of the
