A device for acquiring spectral information of field crops

Abstract

The invention discloses a device for obtaining spectral information of field crops, which includes a platform main body, a wheelbase adjustment mechanism, a platform lifting mechanism and at least two independent walking mechanisms, and the independent walking mechanisms are respectively arranged on two sides of the platform main body. On the side, each of the independent walking mechanisms is fixedly connected to the lower end of a platform lifting mechanism, and the wheelbase adjusting mechanism is movably connected to the platform lifting mechanism, and the wheelbase adjusting mechanism can move along the platform lifting mechanism. Moving up and down, the wheelbase adjustment mechanism can adjust the width between the independent walking mechanisms on both sides of the platform main body, the platform main body is fixed on the wheelbase adjustment mechanism, and the platform main body is used to place Spectrum camera. The invention makes the spectral information acquisition device suitable for information acquisition of various crops with different plant heights and different planting widths, so as to realize the acquisition of crop near-ground canopy information, and can significantly improve 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
