| 摘 要： | 三维激光扫描技术由于可快速获取高精度、高密度点云数据，可将拟验收建筑及周边情况几乎完全无差地复制到电脑中，是规划验收测量特别是复杂建筑规划验收测量的理想方法，但是其数据处理一直是影响甚至制约其应用的瓶颈。本文简述了规划验收测量要点，以及三维激光扫描点云数据初步处理流程，并针对制作规划验收测量各类图件的不同需求，提出了分别通过直接取线、切片、投影等方法制作成果图件的工作思路及各方法的特点。但是还需研究和解决海量点云的数据处理，以及根据验收测量特点获得测量成果图件的问题。

| Abstract: | Three-dimensional laser scanning technology can quickly acquire high-precision and high-density points cloud data, what's more, it can also copy the proposed acceptance of the buildings and their surrounding environment to the computer almost completely without error. And it is an ideal method for planning and acceptance measurement, especially for complex buildings planning acceptance measurement. However, its data processing has always been a bottleneck affecting or even restricting its application. This paper briefly described the main points of planning acceptance measurement and the preliminary processing flow of 3D laser scanning points cloud data. In view of the different requirements for making various kinds of plans acceptance measurement maps, the working ideas and characteristics of each method for making the results maps by direct line-taking, slicing and projection were put forward. And in view of the different requirements of making various drawings of planning acceptance measurement, this paper put forward the working ideas and characteristics of each method of making the results drawings by direct line-taking, slicing, projection and so on. However, it is necessary to research and solve the problem of data processing of massive point clouds and obtaining surveying results maps according to the characteristics of acceptance measurement. |
