摘要
研究和建立了一套无人直升机低空数字摄影与影像测量系统。该系统以无人直升机为飞行平台,以数字相机为传感器,直接获取高分辨率数字影像,具有垂直升降、低空作业、自主飞行等特点。详细介绍了该系统的工作原理,总结了航空摄影关键参数的设计方法,同时,提出了视距网格的飞行模式,增强了系统安全性;利用试验场相机检定的技术,实现了非量测数字相机在摄影测量中的应用。最后介绍了该系统在15 km2大比例尺测绘工程中的应用情况以及综合精度检测结果。
This paper studied and founded a low aerial photography and photogrammetry system by unmanned helicopter. By using unmanned helicopter remote sensing platform and a digital camera, the high-resolution digital photography could be captured directly. The advantages of this system were summarized as follows： vertical take-off and landing, low altitude flying, fully autonomous flight control. In this paper, we introduced the system＇ s principle and summarized the method of designing the aerial photography＇ s key parameters. At the same time, we put forward the flying model of sight-range grid. Thus, it could enhance the system＇ s security. By using the technique of camera calibration in experiment felid, we realized the photogrammetry application with non-surveying digital camera. Finally, the paper introduced the application and precious checking results by making this system applied in the 15 km^2 fields of a largescale survey and mapping.
