基于近景目标3维测量系统和CSG技术构建3维景观

Constructing 3D Landscape Models Based on 3D-Surs and CSG Technology

针对构建建筑物模型的过程,基于CSG体素,将建筑物进行体分解;以构建CSG树技术对建筑物进行3维重建。车载式近景目标3维测量系统(3D-Surs)提供的建筑物3维空间数据和纹理数据,为应用CSG技术奠定了数据基础。本文提出了基于3D-Surs和CSG技术构建建筑物3维模型的流程,并对该技术和流程进行了实践检验。实践表明本文的技术方案可行,具有推广价值。

By introducing the process of making the construction models, this paper put forward the ways to decompose the construction based on CSG unit, and compose the construetion＇s 3D landscape with CSG-Tree. The 3D spatial data and the texture data from the 3D-Surs offer the data-base to apply the CSG technology. This paper gave the scheme to construct the 3D-model based on the 3D- Surs and CSG technology and then put the technology and scheme into practice. The result showed that this technology scheme is feasible and can be taken as a reference.
