Abstract

Abstract: To enhance the efficiency of urban rooftop photovoltaic (PV)energy utilization and explore the application fields of real-scene 3D models,this paper proposes a method for optimizing the layout of rooftop photovoltaic panels driven by UAV (unmanned aerial vehicle)real-scene 3D models.The method employs UAV oblique photogrammetry to establish the real-scene 3D model of buildings and combines GIS spatial analysis algorithms to conduct fine-grained sunlight analysis and PV panel layout optimization.Firstly,the real-scene 3D model is optimized through selecting an appropriate level of detail (LOD)and reconstructing triangular meshes into quadrilateral meshes to improve the efficiency and accuracy of sunlight analysis.Subsequently,a parametric sunlight analysis module is developed to dynamically calculate the solar irradiance duration on the rooftop based on meteorological data,and utilizable areas are identified according to the peak sun hours.On this basis,GIS spatial analysis methods are applied to remove the influence of rooftop obstacles,demarcate the PV panel layout area,and design an optimized layout algorithm to achieve dynamic layout and visualization of rooftop PV panels.The study shows that this method can effectively improve the utilization rate of rooftop space and provide technical support for the scientific layout of building rooftop PV systems.

Key words: real-scene 3D model, rooftop photovoltaics, sunlight analysis, spatial analysis, optimized layout of photovoltaic panels
