Abstract

The embodiment of the invention relates to the technical field of farmland intelligent management, and discloses a method and system for determining the water content of field crops under multiple spectrums and equipment. According to the embodiment of the invention, the method comprises the steps: acquiring to-be-processed multispectral remote sensing data corresponding to field crop leaves; processing the to-be-processed multispectral remote sensing data to obtain vegetation index data; performing image synthesis operation based on the vegetation index data to obtain a target image; and processing the target image according to a preset inversion model to obtain current crop water content information. Therefore, according to the embodiment of the invention, the water content of the current crop is determined through the target image instead of measuring the water content of the crop on site by using an instrument, so that the detection speed is greatly increased, and the technical problem of low detection efficiency when the water content of field crops is detected is solved.

Description

technical field [0001] The invention relates to the technical field of farmland intelligent management, in particular to a method, system and equipment for determining the water content of field crops under multi-spectrum. Background technique [0002] Considering that water is one of the indispensable elements for the normal growth and development of plants, in the production process of field crops, the leaf water of plants can be quickly detected and obtained, which is very important for the irrigation production management of field crops and the physiological water demand characteristics of crops. Research etc. are of great significance. [0003] At the same time, water content is an important indicator of crop growth status. Timely and accurate monitoring and diagnosis of crop water content is also of great significance for improving agricultural irrigation efficiency and guiding agricultural production. [0004] In addition, compared with soil water content, leaf water...
