摘要
三维激光扫描仪能够快速、准确地获取物体表面的点云数据,具有传统测量方法无法比拟的优势。详细介绍了三维激光扫描仪在城市地下空间测绘中的作业流程及数据处理方法。结合工程实例,利用采集的点云,获得地下空间的二维平面图及三维模型,并对测量精度进行了验证。
The 3D laser scanner can obtain the point cloud of the object surface quickly and accurately,which has the advantage that the traditional measurement can't match.This paper introduces application of 3D laser scanner and data processing method in urban underground space surveying and mapping in detail.Combined with the engineering example,the 2D map and 3D model of the underground space are obtained using the point cloud,and the measurement accuracy is verified.
