The invention relates to the technical field of satellite remote sensing calibration and authenticity inspection, and provides a surface reflectance measurement method based on a rotor unmanned aerial vehicle, which comprises the following steps: selecting an eight-rotor unmanned aerial vehicle as a surface reflectance observation aviation platform, and additionally installing an SVC spectrometer fiber holder between two rotor arms on the side surface of the eight-rotor unmanned aerial vehicle; making a corresponding aviation flight scheme; the eight-rotor unmanned aerial vehicle is arranged at a take-off point of a flight route; planning passing points and landing points and uploading to the eight-rotor unmanned aerial vehicle; selecting a polytetrafluoroethylene pressed white board as a standard reference board; respectively measuring and collecting data of the standard reference plate before taking off and after landing, and completing the measurement of the surface reflectance of one sortie; and calculating the surface reflectance after time correction according to each parameter, and repeating the steps until all sorties of surface reflectance measurement tasks are completed. According to the invention, a lot of manpower and material resources are saved, the site is effectively protected, the calibration precision is improved, and the measurement efficiency of the surface reflectance is effectively improved.

    本发明涉及卫星遥感定标与真实性检验技术领域,提供了一种基于旋翼无人机的地表反射率测量方法,包括:选择八旋翼无人机作为地表反射率观测航空平台,在八旋翼无人机侧面两旋翼臂之间加装SVC光谱仪光纤云台;制定相应的航空飞行方案;将八旋翼无人机置于飞行航线的起飞点;规划途经点和降落点并上传至八旋翼无人机;选择聚四氟乙烯压制白板作为标准参考板;起飞前和降落后分别测量并采集标准参考板数据,完成一个架次地表反射率测量;根据各参数计算时间修正后的地表反射率,重复上述步骤,直至完成所有架次的地表反射率测量任务。本发明节省了大量人力物力,效保护了场地,提高定标精度,有效提高地表反射率的测量效率。
