摘要： The present invention proposes an evaluation method of solar energy utilization potential in urban high-density areas based on low-altitude photogrammetry, comprising the following steps: low-altitude data acquisition using drones, acquisition of three-dimensional point cloud data, screening of building subject points, selection of seed region, region growth and point cloud patch segmentation, three-dimensional reconstruction, building geometry model, solar radiation simulation and solar energy utilization potential assessment steps. The invention utilizes low-altitude photogrammetry to obtain point cloud data in a high-density area of the city, and performs semantic division and three-dimensional reconstruction on the point cloud data through a parameterization tool to obtain a singular geometric model. Therefore, the solar radiation and dynamic change obtained from the roof and facade of the building are simulated and analyzed in the same platform.
