摘要: 无人机航测技术近年来被广泛应用于测绘系统中。本文利用天狼星无人机摄影测量技术,采用GNSS实时动态差分、高精度测时与数据处理技术,在免除布设相控点的条件下完成了测区内1:2000比例尺DOM、DEM、DLG数据的生产,经检验测区精度满足大比例尺成图规范要求。基于高重叠率相片与精确POS数据进行数据三维建模处理,生产模型可以满足大型施工项目可研阶段的数据需求。结果表明,天狼星无人机航测系统适合测绘大比例尺成图与三维建模工作,可以为设计施工部门提供准确直观的基础数据。

Abstract: Unmanned aerial vehicle (UAV) aerial survey system has been widely applied in surveying and mapping engineering area. Based on Sirius unmanned vehicle photogrammetry system, 1:2000 scale data of DOM, DEM, DLG are generated in the survey area by using GNSS real time dynamic difference and high precision measurement with data processing technology. Through analyzing the survey area accuracy, the results satisfy the requirement of large scale map specification. Taking the high overlap rate image and precision POS data, the generated data is input to connection client software for 3D modeling processing. The production model can provide data basis for large construction-engineering development. The conculsion shows that Sirius UAV is suitable for surveying and mapping large scale area and 3D modeling, thus providing visual and precise basic data for design and construction deparment.

Key words: Sirius UAV, aerial photogrammetry, DEM, DOM, 3D modeling
