Device for obtaining spectral information of field crops

Abstract

The invention discloses a device for obtaining the spectral information of field crops. The device comprises a platform main body, a wheel track adjusting mechanism, a platform lifting mechanism and at least two independent travelling mechanisms; the independent travelling mechanisms are arranged on the two sides of the platform main body; each of the independent travelling mechanisms is fixedly connected with the lower end of the platform lifting mechanism; the wheel track adjusting mechanism is movably connected with the platform lifting mechanism, can move up and down along the platform lifting mechanism, and can adjust the width between the independent travelling mechanisms on the two sides of the platform main body; the platform main body is fixed on the whee track adjusting mechanism; and a spectral camera is placed on the platform main body. The device is suitable for information acquisition of various crops with different heights and different planting widths to obtain information of crop canopy close to the ground and remarkably increase the information acquisition rate.

Description

technical field [0001] The invention relates to the technical field of agricultural detection equipment, in particular to a device for acquiring spectral information of field crops. Background technique [0002] Plant canopy spectral data can reflect comprehensive information such as the composition distribution, growth status, and canopy structure of the entire canopy. The acquisition and analysis of canopy spectral information through spectral technology has the advantages of simple, fast, intuitive, high-precision and non-destructive measurement. It has become an important means of obtaining spectral images of plants such as rapeseed, corn, and sorghum, and has good application prospects in plant growth monitoring, nutritional diagnosis, precise fertilization management, yield estimation, and disease monitoring.

AI Technical Summary

Problems solved by technology

Spectral systems based on drones are widely used in the field of field crop spectral data acquisition, but the spectral data obtained lack details and canopy information near the ground. For this reason, technicians in the field use laboratory large-scale spectral instruments and manual Hand-held spectrometers obtain detailed information on a single plant or a small number of crops, but the information acquisition rate is extremely low
