摘要
针对无人机低空摄影测量技术应用于大比例尺测图中存在的解算外方位元素问题,本文采用光束法区域网平差解算像片的外方位元素,并结合某工程项目,详细叙述了光束法区域网平差的流程,深入评估了无人机低空摄影测量技术应用于大比例尺地形图的测图精度。统计精度结果表明,低空无人机摄影测量可满足大比例尺测图的要求,验证了无人机技术在地形图测图中的有效性和适用性。
In order to solve the problem of external orientation elements in the application of UAV low altitude photogrammetry technology to large scale mapping,this paper uses the beam method area network adjustment to solve the external orientation elements of the photograph,and describes the overall process of beam method area network adjustment in detail based on an engineering project.The mapping accuracy of UAV low altitude photogrammetry technology applied to large scale topographic map is further evaluated.The statistical accuracy results show that the photogrammetry of low altitude UAV can meet the requirements of large scale mapping,and it also verifies the effectiveness and applicability of UAV technology in topographic mapping.
