| 摘 要： | 无人机搭载高分辨率传感器,获取的正射影像和数字表面模型(DSM),能够很好的反映精细地形表面特征。本文以藏东南地区雅弄冰川末端为研究区,利用M300 RTK无人机搭配睿铂M6P量测型相机,获得了地面分辨率为1.5 cm的正射影像及DSM。与航天遥感数据Planet影像和数字高程模型TanDEM相比,无人机航测获取的正射影像、DSM在提取冰川边界、冰川表面形态上具有较大优势。本文利用坡度阈值法、R成像波段阈值法,能够有效提取冰裂隙、冰面湖的分布,且自动提取误差小于10%。因此,无人机航测获取冰川区精细地形在未来冰川研究中具有非常大的潜力,尤其是提取冰面特殊形态,研究微尺度地形对冰川变化的影响。

| Abstract: | The orthoimage and Digital Surface Model （DSM）， acquired by the unmanned aerial vehicle （UAV） with high resolution sensors， could reflect the fine terrain accurately. In this study， the terminus of Yanong Glacier in southeastern Tibetan Plateau was chose as the study area. The orthoimage and the DSM with the resolution of 1.5 cm were acquired by the UAV of M300 RTK with M6P camera. Compared to Planet image and TanDEM， the orthoimage and the DSM present the surface feature and fine terrain in glacier area accurately. Based on the methods of slope threshold and Red band threshold， the special morphologies of glacier surface， such as ice cliff and glacial lake， were extracted automatically， and the uncertainties of extraction were lower than 10%. Hence， the fine terrain in glacier area， acquired by UAV with high resolution sensors， has great potential in the future glacier research. |
