城市建筑物太阳能资源潜力评价系统设计与实现

摘要

针对现有三维阴影分析方法及软件无法满足建筑物尺度太阳能潜力估算的问题，提出将遥感反演的太阳辐射参数与三维遮挡分析统一的软件设计思路。根据建筑物尺度的太阳能潜力评价需求，在Eclipse平台上，运用C／C＋＋语言和OpenGL图形程序接口，实现了基于LiDAR点云及遥感影像的三维模型构建，静态及动态的阴影模拟，以及相应的太阳能潜力的估算和可视化。结果可为太阳能设备的选择、安装提供技术支持。%For the problem that current three-dimensional (3D) shadow analysis method and software cannot satisfy the estimation of solar energy potential of urban dimension, in this paper we propose a software design idea of unifying the solar radiation parameters retrieved from remote sensing data and the 3D occlusion analysis.According to assessment requirements on solar energy potential of building dimension and on Eclipse platform, we use C/C++language and OpenGL graphics programming interface to have realised the building of 3D model which is based on LiDAR point cloud and remote sensing images, the static and dynamic shading simulation and the corresponding estimation and visu-alisation of solar energy potential, the result can provide technical support for the selection and installation of solar-related appliances.
