The invention relates to an unmanned aerial vehicle-mounted linear array hyperspectral BRDF rapid construction method and system considering illumination, and mainly solves the problems that according to an existing BRDF collection method, collected BRDF data are not high in dimension richness, data continuity is difficult to guarantee, the influence of illumination change on data is rarely considered, and the construction efficiency is low. And the BRDF acquisition and construction efficiency of a complex environment is low. The system comprises a hyperspectral imager, an atmospheric downlink irradiance measuring device and a correction calibration assembly, the hyperspectral imager is used for being installed on an unmanned aerial vehicle and obtaining BRDF data of a target collection area. The atmosphere downlink irradiance measuring device is used for being arranged on the ground and acquiring data of illumination changing along with time; and the correction and calibration assembly is arranged at the target acquisition area and is used for acquiring correction and calibration data.
本发明涉及一种考虑光照的无人机载线阵高光谱BRDF快速构建方法及系统,主要解决现有BRDF采集方法存在采集到的BRDF数据维度丰富性不高、难以保证数据的连续性,且很少考虑光照变化对数据的影响,对于复杂环境的BRDF采集和构建效率较低的技术问题。该系统包括高光谱成像仪、大气下行辐照度测量装置和校正定标组件;所述高光谱成像仪用于安装在无人机上,获取目标采集区域的BRDF数据;所述大气下行辐照度测量装置用于设置在地面上,获取光照随时间变化数据;所述校正定标组件设置于目标采集区域处,用于采集校正定标数据。
