无人机在矿区1∶2000地形测绘中的应用研究

Research on application of UAV in topographic mapping with 1: 2 000 scale in mining area

以无人机航摄技术在矿区1∶2 000大比例尺地形图测绘中的应用为研究目的,采用复合翼无人机搭载非量测相机,对甘肃某矿区进行了地形图快速测绘与更新,生产了该矿区1∶2 000地形图和矿区的正射影像图。通过外业施测像控点对测图高程精度的检测与分析,结果表明:通过提前布设地标点,严控飞行质量等误差影响因素,此无人机可满足矿区1∶2 000航测成图。

Taking the application of UAV aerial photographing technology in mapping of 1: 2 000 large-scale topographic mapping in mining area for the purpose of research,non-metric camera equipped with hybrid wing UAV was used to rapidly map and update topographic maps of a mining area in Gansu Province,1: 2 000 topographic mapping and orthographic image of the mining area were produced. Elevation accuracy of surveying map was tested and analyzed by field operations measurement like control point,the experimental results showed that the UAV aerial photography could meet the requirements of 1: 2 000 scale mapping accuracy through the technical measures such as laying ground punctuation and controlling the flight quality and other error factors.
