摘　　要：以3ds Max脚本(MAXScript)建模为主、手动组合变电站建筑物单体为辅,提出一种基于三维激光扫描点云数据的变电站三维模型构建方法。所提方法能够解决变电站三维建模中手工建模效率低和模型可扩展性差等问题。以云南省富源县某110 kV变电站三维建模为例展开实验,实验结果表明,所提方法在一定程度上可满足精度要求,并且能够降低变电站的建模成本,提高变电站的建模效率。Taking 3ds Max script(MAXScript)as the main modeling and manual assembly of substation buildings as a supplement,a method for constructing 3D substation models based on 3D laser scanning point cloud data is proposed.The proposed method can solve the problems of low efficiency of manual modeling of substation 3D modeling and poor model scalability.Taking the 3D modeling of a 110 kV substation in Fuyuan County,Yunnan Province,as an example,the experimental results show that the proposed method can meet the accuracy requirements of the model to a certain extent and can reduce the modeling cost of the substation and improve its modeling efficiency.
