摘要: 在高精度实景三维模型生产中,无人机平台与载荷的选择及像控点布设十分重要,对航摄效率、模型精度、效果均有影响。本文以我国北部某城镇村为研究区域,利用不同的无人机倾斜摄影测量设备分别获取同分辨率倾斜影像,并结合不同的像控点布设方案重建实景三维模型。通过同等分辨率原始影像的不同装备及像控点布设的组合方案构建对照试验组,对比验证并分析飞行效率、模型精度及模型效果,选取满足高精度实景三维模型重建要求的设备类型及经济合理的像控点布设方案,为实际的生产作业提供指导。

Abstract: In the production of high-precision 3D real scene models, the selection of UAV platforms and loads and the laying of image control points are of great importance, which affect the efficiency of aerial photography, model accuracy, and model effects. In this paper, an urban village in north of China is used as a research area, and different UAV oblique photogrammetric equipments are used to obtain oblique images of the same resolution respectively, and combined with different image control point laying schemes to reconstruct the 3D model of the real scene. Through different equipment and image control point laying combinations, and original images of the same resolution, a test group is formed to compare and analyze flight efficiency, model accuracy and model effect. Thus, equipment selection and economical and reasonable image control point layout for meeting high-precision 3D real scene model reconstruction requirements are studied so as to provide guidance for actual production operations.

Key words: oblique photography, 3D real scene model, image control point layout, UAV platforms and payloads
