摘　　要：以某抽水蓄能电站的三维实景模型制作为研究背景,以无人机倾斜摄影单镜头、五镜头的两种影像作为数据源,分别生产三维实景模型数据,实验比较两种模型的纹理清晰度和几何精度。结果表明,在相同的像控点约束情况下,两类模型数据均能满足1∶500地形图精度要求,但基于五镜头影像生产的的模型数据,精度更高,纹理更加清晰,整体精度更加均匀。Taking the production of a 3D real-world model of a pumped storage power plant as research background,two kinds of images from single-lens and five-lens tilt photography by drones are used respectively as data source to produce 3D real-world model,and the texture sharpness and geometric accuracy of the two models are compared in experiments.The results show that under the same image control point constraints,the two types of model data can both meet the precision requirements of 1∶500 topographic maps,but the model data produced based on five-lens images has higher accuracy,sharper texture,and better overall accuracy.
