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.

Key words: 3D laser scanning points cloud data, planning and acceptance measurement, area computation, acceptance and measurement stereogram
