Abstract: An efficient method for façade 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 façade 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 façade,and can be easily applied for useful applications,like sunlight duration test in architecture,and estimation of solar irradiance on windows.
