摘　　要：随着无人机测绘技术的不断成熟,消费级无人机也可以搭载数码相机、全球导航卫星系统(GNSS)、惯性测量单元(IMU)等传感器,使其制作大比例数字化产品成为可能。文中以大疆PHANTOM 4实时动态载波相位差分技术(RTK)消费级无人机为研究对象,以辽宁科技大学校园为研究区,验证在免像控状态下,消费级无人机制作的大比例尺数字线划图所能达到的精度。研究结果表明:大疆PHANTOM 4 RTK消费级无人机在免像控状态下,平面完全能够满足1∶500数字化测图的精度要求,高程存在个别点超限现象,1∶1000数字化测图中能够同时满足平面和高程的精度要求。As unmanned aerial vehicle(UAV)surveying and mapping technology develops,consumer-grade UAVs can be equipped with digital cameras,global navigation satellite systems(GNSSs),inertial measurement units(IMUs),and other sensors,making it possible to produce large-scale digital products.This paper took DJI PHANTOM 4 real time kinematic(RTK)consumer-grade UAVs as the research object and Liaoning University of Science and Technology as the research area to verify the accuracy that can be achieved by large-scale digital line graphic(DLG)made by consumer-grade UAVs under the image-free control state.The study shows that the DJI PHANTOM 4 RTK consumer-grade UAVs are fully capable of meeting the accuracy requirements of 1∶500 digital mapping in the plane under the image-free control state,but there exist individual points with over-limit phenomena in elevation.They can satisfy both accuracy requirements in 1∶1000 digital mapping in terms of plane and elevation.
