基于地面三维激光扫描数据的快速建模

A Fast Modeling Method Based on Terrestrial 3D Laser Scanning Data

三维激光扫描技术具有速度快、精度高、自动化程度高并且不与物体直接接触等诸多优点,现已应用于古建筑保护、数字城市、工业生产、地形测绘等不同领域。本文利用地面三维激光扫描仪对校内樱花园手形建筑物进行扫描,获取该目标物的点云数据,并对获取的点云数据进行拼接、去噪处理。同时,利用点云数据处理软件Geomagic对目标物进行快速的三维模型重建并达到了预期的效果。

3D laser scanning technology has advantages of high speed,high precision,high density, high automation and indirect contact with the object, and many other advantages.This technology has been applied to the protection of ancient buildings, digital cities, industrial production, topographic mapping and other fields.In this paper, we used the terrestrial laser scanning equipment to scan school building cherry garden-hand, getting the point cloud data of the object, and was dealt the point cloud data with splicing and demising.Point cloud data processing software Germanic was used to fatly reconstruct the 3D model of the object, and desired results are achieved.
