倾斜摄影测量三维建模及精度分析

3D Model Establishment and Accuracy Analysis of Oblique Photogrammetry

无人机航测是近年来新兴的测量技术,其中,像控点布设是无人机三维模型制作的关键环节之一。本文以黑龙江省五常市某区域为实验区域,通过地面实测像控点和检查点,采用4种像控点布设方案,进行三维建模的实验及其精度分析。实验研究表明,无人机航测像控点,4种布设方案生成的实景三维模型精度都能满足我国的CH/T9015-2012《三维地理信息模型数据产品规范》,可为今后无人机测量应用提供依据。

The UAV aerial survey is an emerging surveying and mapping technology in recent years,in which the control point layout is one of the keys to the establishment of the 3D model.In this paper,a certain area of Wuchang City,Heilongjiang Province is used as the experimental area.Through the ground measurement of image control points and checkpoints,four kinds layout schemes of image control point are used to carry out 3D modeling experiments and precision analysis.The experimental research shows that the accuracy of the 3D model generated by the four layout schemes of the aerial survey image control points of UAV can meet the CH/T9015-2012"3D Geographic Information Model Data Product Specification"of China,which can provide for future UAV measurement applications.
