三维激光扫描技术在地下建筑三维建模中的应用研究

Research on the Application of 3D Laser Scanning Technology in the Construction of 3D Modeling of Underground Building

地下建筑的三维建模日益受到人们重视,本文以长春市某地下车库为实例,对其进行三维建模,介绍了利用三维激光扫描技术进行地下车库三维建模的方法,分析了点云数据的测量精度。结果表明,与传统方法相比,建模的精度和效率都有很大提高,对地下建筑的三维建模具有借鉴意义。

Underground structures of 3d modeling attracting increasing attention, this article takes an underground garage in Changchun city as an example to construct 3d modeling of it,introduces the way of using 3d laser scanning technology to build 3d modeling of the underground garage, and analyze positional accuracy of the method. Results show that compared with the traditional method, the precision and efficiency are greatly improved, and instructive to the un- derground construction of the 3d modeling.
