Description

technical field [0001] The invention relates to the fields of ground object spectral observation, surface ecological parameter remote sensing signal detection, and agricultural precision management, and in particular relates to a multi-angle remote sensing spectral detection device for crop growth and its use method. Background technique [0002] The interaction between light and matter causes electronic transitions between the energy levels of atoms and molecules inside the matter, causing changes in the wavelength and intensity information of the matter’s absorption, reflection, emission, and scattering of light. The intensity information at the wavelength position forms a continuous curve, which is the spectral curve. The main factors affecting the change of the spectral curve are the composition, structure and surface state of the object. If the recorded intensity information represents the reflection intensity of the object to light, the spectral curve is often called ...
