Abstract

The invention discloses a crop growth multi-angle remote sensing spectral detection device and a use method thereof. The device comprises an upright column; a control box is arranged on the upright column; an observation pipe is arranged at the top of the upright column; a crop canopy reflective spectral curve detection device is arranged at one end of the observation pipe; and a solar incidence spectral curve detection device is arranged at the other end of the observation pipe. The crop growth multi-angle remote sensing spectral detection device can integrate two spectrometers with differentwavelength ranges and different spectral resolution, realizes double-channel synchronous spectral detection, greatly reduces time difference among data and enhances comparability among data; the cropcanopy is subjected to different remote-sensing sensor spectral detection by utilizing double-channel design, the consistency of the detected target objects is guaranteed, and the reliability and thecredibility of long-time sequence data analysis result and scientific research are guaranteed; due to the automatic tracking solar and multi-angle detection crop canopy spectral curve, the data precision is improved and the credibility of a remote-sensing monitoring model is enhanced; the crop growth multi-angle remote sensing spectral detection device is simple in structure, convenient to use and convenient to carry and use in the field; and the cost is saved.

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 ...
