小区域消费级无人机倾斜摄影像控点布设及建模精度研究

像控点布设是无人机倾斜摄影施测阶段的重要环节，直接决定后期三维实景模型的精度。本文面向校园等小区域环境，利用消费级单镜头多旋翼无人机航摄系统获取影像数据，重点设计了不同像控点布设方案，基于全自动数据处理系统进行空三加密及三维模型的构建，并对模型成果进行精度分析，为实际工作中小区域像控点的布设提供建议和指导。

Research on the control point layout scheme for consumption-grade UAV oblique photogrammetry in small areas and modeling accuracy

The control point layout scheme is an important part in the surveying stage of the unmanned aerial vehicle(UAV) oblique photogrammetry, which directly determines the accuracy of the later 3D real scene model. In this paper, aiming at campus and other small-area environments, and using the consumption-grade single-lens multi-rotor UAV aerial photography system to obtain the image data, different control point layout schemes are designed. Aerotriangulation and building 3D model based on automatic data processing system, accuracy analysis of model results is carried out. The suggestion and guidance are given for the layout of the control point in small areas for the actual work.
