摘　　要：三维激光扫描技术是通过大量密集的扫描点,以模拟形式体现目标实体对象表面丰富的形体信息,不能获取的点云数据直接读取目标对象的矢量化信息,并进行点云数据处理。笔者在工作中,以EPS2008软件平台为基础,利用VBScript脚本进行二次开发,实现了点云数据分层提取、点云线状地物提取、点云特征轮廓提取、点云数据断面提取和点云高程提取等功能。本文针对已经实现的功能进行探讨,指出每种方法的特点和应用范围。3D laser scanning technique is a new technique that it can show abundant shape information of entity object on surface through a great deal of dense scanning points .Vector information in the object can ’ t read directly with the point cloud data obtained . It needs to process .Based on EPS2008 software platform , the author uses VB script to realize secondary development and also a-chieves some functions such as point cloud data extracted in layers , linear features extracted of point cloud , feature contour extracted of point cloud , profile extracted of point cloud and the extraction of point cloud ’ s elevation and etc .The article discusses the function carried out and indicates the characteristic and the application range of each method .
