影响无人机航摄的高程精度分析

Analysis of Elevation Accuracy Affecting UAV Aerial Photography

目前无人机技术在测绘行业中应用愈加广泛,更多从业人员将无人机应用在与高程测量有关的场景,但影响航摄高程精度的因素较多,怎样采取一定举措以提高航摄高程精度已成为业内人员更加关心的问题。在进行精度探究时多从DLG成图角度来分析,未就高程精度影响因素进行探讨,文章基于理论分析与实验验证,结合航摄技术作业流程探讨了在航摄作业时高程精度的影响因素,提出了合适的航测设计方法,可为今后航测工作提供一定参考。

At present,UAV technology is more and more widely used in the surveying and mapping industry,and more practitioners will apply UAV in scenarios related to elevation measurement,but there are many factors affecting the elevation accuracy of aerial photography,and how to take certain measures to improve the elevation accuracy of aerial photography has become a more concerned issue in the industry.In the precision exploration,most of the analysis is from the perspective of DLG diagram,and the factors affecting the elevation precision are not discussed.Based on theoretical analysis and experimental verification,combined with aerial photography technical operation process,this paper discusses the influencing factors of elevation accuracy in aerial photography operations,and proposes appropriate aerial survey design methods,which can provide certain reference for future aerial survey work.
