摘要
研究了旋翼无人机在大比例尺航测成图中的一些技术问题,通过生产实践中的探索,尝试着将大疆筋斗云S1000+八旋翼无人机与禅思云台和SONYα7R微单相机相结合,自主研发了一套适用于大比例尺航测成图的旋翼无人机摄影测量系统。结合试验数据,详细描述了该系统用于测绘大比例尺地形图的具体工作流程,研究分析了在相同旁向重叠和航向重叠情况下,不同航高对航测地形图成果平面精度和高程精度影响问题,为同类型旋翼无人机航摄系统测绘大比例尺地形图提供了可行性评价和生产实践经验。
Some technical problems of the rotor unmanned aerial vehicle(UAV)in large scale aerial mapping is studied,and through the exploration in the production practice,try to put the DaJiang S1000+8 rotor unmanned aerial vehicle(UAV)combining with ChanSi YunTai and SONY alpha 7 Rsingle camera,that a set of suitable for large scale aerial mapping of rotorcraft UAV photogrammetry system is researched.Combined with the test data,the work of surveying and mapping process that the system used in large scale topographic map of specific is described in detail,and in the same case of lateral overlap and longitudinal overlap,the plane precision and height precision of photogrammetric topographic map achievement affected by different flying height is studied,which can provides the feasibility evaluation and production practice experience for the same type rotor UAV aerial photography system of surveying and mapping the large scale topographic map.
