基于移动激光扫描系统Trimble MX8的杆状地物提取研究

介绍车载移动三维激光扫描测量系统的发展和特点,以及Trimble MX8系统的构成和功能应用,重点阐述当前国内学者从激光点云数据中提取杆状地物的方法.通过选择两条不同的道路,在不同道路环境下应用不同的参数对杆状地物进行提取,显示不同的提取结果.通过对实验结果进行对比分析得出：面对不同的道路环境,采用相适宜的参数,再加以人工细致的检查,从激光点云数据中提取杆状地物的结果还是可以满足需要的.

Extraction of poles based on 3D vehicle-borne mobile laser scanning and surveying system

It presents the development and features of the 3D vehicle-borne mobile laser scanning and surveying system before giving an introduction of the structure and function application of the Trimble MX8 system. Following that, it elaborates the study of methods on extracting poles from laser point cloud data at present in China. Besides, it selects two different roads and performs a test on extractions of poles with different parameters and under different road environments, from which different results of extraction are collected. At last, on the basis of comparative analysis of the results, it concludes that for different road environments, the results derived from applying appropriate parameters with careful manual inspection in extracting poles from laser point cloud data can be satisfactory.
