Abstract
A real-time radiometric correction method and an apparatus for spectral reflectance are provided. The method includes: obtaining photosynthetically active irradiance measured by a photosynthetically active radiation sensor, where the photosynthetically active radiation sensor includes a cosine corrector; obtaining photosynthetically active irradiance of a target band based on a proportional relationship between the photosynthetically active irradiance and downwelling solar irradiance within a same wavelength range, where the target band is any band in a spectral band obtained by an imaging hyperspectral sensor, and an imaging time point of the imaging hyperspectral sensor is synchronized with a measurement time point of the photosynthetically active radiation sensor; and performing weighted adjustment on the photosynthetically active irradiance of the target band to obtain corrected target irradiance of the target band.
