摘要: 无人机遥感技术以其以低成本、低风险、高时效及可产生高分辨率影像的优势,成为较先进的森林资源调查手段。本文阐述了可搭载于无人机平台上的光学、红外、高光谱、激光雷达和合成孔径雷达载荷的发展现状,并针对森林资源调查需求,总结了不同载荷下国内外森林特征参数提取方法和技术的优缺点。最后,分析了无人机遥感技术应用于森林资源调查中存在的问题,并对这一技术的未来发展趋势进行展望,为无人机遥感技术在我国森林资源调查中应用提供参考。Abstract: Descriptions were made on current situation of UAV equipped with different sensors such as in frared optics, high spectrum, laser radarand synthetic aperture radar. Summaries were conducted on forest resources survey like forest characteristic parameters, division of subcompartment,conservation rate of afforestation, forest fire, forest pest by different sensors equipped on UAV at home and abroad. The problems were analyzed anddevelopment trend in the future was prospected.
