摘要
拓普康天狼星无人机通过整台精密测时技术和RTK定位技术来确定每张航片拍摄的准确位置,这种精密定位技术实现了利用低空无人机制作1:500比例尺的地形图测绘。通过在某风电场220 kV升压站测图中的应用表明,该系统制作的平面精度和高程精度均符合相关规程的要求。与传统无人机航空摄影测量模式不同,无须布设像控点,极大提高了工作效率,节省了生产成本。
Topcon Sirius UAV determines the accurate location of each aerial photo shoot, through the whole precision measurement technology and RTK positioning technology. The use of this kind of precision positioning technology achieves the low altitude UAV making 1：500 scale topographic map, experiments show that the system made of plane precision and elevation accuracy are accord with the requirement of relevant procedure specification. And it brakes through the traditional model of aerial survey, needs not to laid aerial photo as the locus of eontrol, greatly improves the working efficieney and saves the cost of production.
