On Campus Building Modeling Based on the Terrestrial Three-dimensional Laser Scanning System

基于地面三维激光扫描系统原理和特点,在确定校园建筑物三维模型创建实现流程的基础上,以校务大楼为对象,利用地面三维激光扫描系统进行数据采集,对噪声去除、数据配准及拼接、数据消冗等关键技术及实现步骤、方法进行研究。通过特征线提取建立被测物体的线框模型,利用3DS Max软件完成了三维模型的创建,探索了数字校园的实现途径。

Based on the principles and characteristics of the terrestrial three-dimensional laser scanning system, this paper determines the technological process of campus building modeling, taking the adminis- tration building as the research object. It mainly studies the research procedures and methods of data col- lection by using terrestrial three-dimensional laser scanning system, and some key technologies such as noise removing, data registration and data reduction. It first makes the wire frame model of tested object drawing from feature line, then creates three-dimensional model by using 3DS Max. by which a digital campus can be realized.
