摘要
传统大比例尺测图多采用外业实测调绘与内业人工成图的方式,数据采集周期长、人工成本高。为节约成本,提升测图效率,结合实际项目,从航线规划、控制点布设以及实景三维建模等关键技术出发,制定了无人机倾斜摄影大比例尺测图的总体技术流程,并完成精度分析,探究无人机倾斜摄影测量技术在大比例尺测图中的可行性。
Traditional large-scale mapping often adopts the methods of field measurement and manual mapping in the field,resulting in long data collection cycles and high labor costs.In order to save costs and improve mapping efficiency,in combination with practical projects,the overall technical process of unmanned aerial vehicle tilt photography large-scale mapping has been developed starting from key technologies such as route planning,control point layout,and real-time 3D modeling.The completion of its accuracy analysis explores the feasibility of unmanned aerial vehicle tilt photogrammetry technology in large-scale mapping.
