基于激光雷达的建筑物日照分析

Analysis of Building Sunshine Based on Lidar

利用激光雷达获取尼亚加拉大学校园点云数据,基于Terrasolid软件对点云数据进行处理和分析,提取校园建筑物信息,并建立三维建筑模型;利用ARCGIS软件基于阴影检测分析数学模型进行建筑物日照分析研究,在综合应用相关日照原理数据模型的基础上,得出建筑物是否符合建造要求的结论。结果表明,将激光雷达引入日照分析研究具有一定可行性,可提高城市建设的科学性和效率。

In this paper,the point cloud data obtained from the campus of Niagara University using the lidar are processed and analyzed based on Terrasolid software.Then the campus building information are extracted and the three-dimensional building model is established.Based on the mathematical model of shadow detection and analysis,the building sunshine is analyzed by using ARCGIS software to determine whether the building meets the construction requirements.The results show that the introduction of laser radar into sunshine analysis has certain feasibility,which can improve scientificity and efficiency of urban construction.
