摘    要:提出了一种基于多源点云的建筑物立面太阳能潜力估计方法。该方法首先融合地面激光点云和机载影像数据,然后根据融合数据的特点,设计一种基于射线法的日照时长估计算法,并简化用于建筑物立面的太阳辐射模型,从而实现建筑物立面上的太阳能潜力估计。选取2栋朝向不同、形态不同的建筑物进行试验,结果表明,该方法能有效地估计立面上的太阳能潜力,结合点云立面自动化窗户提取的结果,可将结果细化到单个窗户,用于建筑日照标准检验,窗户太阳能潜力估计等应用。

关 键 词:地面激光扫描  机载影像  多源点云  数据融合  建筑物立面  太阳能潜力  射线法

Abstract:An efficient method for fa(c)ade solar potential analysis using multisource point cloud is proposed.Firstly,the terrestrial laser scanning data and the UAV images of study area are fused.Then,a ray-based sunlight assessment algorithm suitable for the fused data is proposed.With the simplified solar irradiance model,the sunlight duration and solar potential on faoade can be finally estimated.Two buildings with different orientations and types were selected to test the method.The results show that our method is efficient in solar potential estimation of facade,and can be easily applied for useful applications,like sunlight duration test in architecture,and estimation of solar irradiance on windows.
