摘　　要：光伏电站占地面积大,传统重建方法因耗费大量人力物力而难以适用于整个光伏电站的构建,结合无人机技术和摄影测量学,提出一种针对光伏电站由粗到细的三维重建系统。该系统利用无人机硬件进行数据采集,随后依据无人机的空间定位与三角测量技术,借助具有重叠度的影像数据,快速构建出粗略的三角网格模型。在此基础上,通过重复性检测和特征匹配并进行模型优化,进一步生成纹理清晰、细节丰富的精细实景三维模型,从而实现光伏电站的高效三维重建。实验结果表明:所提方法能够有效应用于大范围光伏电站的快速三维重建,且重建结果精度高,满足城市数字化模型的精度要求。Given the challenge to constructing entire photovoltaic power stations due to extensive area covered by photovoltaic power stations and high consumptions of labour and resources by traditional reconstruction methods,this paper proposes a coarse-to-fine three-dimensional reconstruction system for photovoltaic power stations by integrating UAV technology and photogrammetry.The system utilizes UAV hardware for data acquisition,followed by rapid construction of a preliminary triangular mesh model based on the spatial positioning of the UAV and photogrammetric triangulation technology,using image data with a certain degree of overlap.Subsequently,through repetitive detection and feature matching,and model optimization,a detailed and realistic three-dimensional model with clear texture is generated,thereby achieving efficient three-dimensional reconstruction of the photovoltaic power station.Experimental results indicate that the proposed method proposed can effectively apply to the rapid three-dimensional reconstruction of large-scale photovoltaic power station and the reconstruction results have high accuracy,which meets the accuracy requirements of urban digital models.
