Abstract

The invention belongs to the technical field of remote sensing, and discloses a crop drought remote sensing monitoring method based on rapid determination of dry and wet edges. The method comprises the following steps: obtaining crop remote sensing image data through an image information acquisition module; respectively detecting the humidity and temperature data information of the crop soil through a soil humidity detection module and a soil temperature detection module; a main control module scheduling a remote sensing image processing module to enhance the acquired remote sensing image of the crop; measuring soil moisture content data information through a soil water content measuring module; and using a data analysis module to carry out comprehensive analysis of the acquired images andthe detected data information. According to the invention, the soil water content / drought condition of the crop soil can be rapidly and effectively estimated through the soil water content measuringmodule to guide agricultural production, water resource planning and the like, and the precision is higher.

Description

technical field [0001] The invention belongs to the technical field of remote sensing, and in particular relates to a crop drought remote sensing monitoring method based on rapid determination of dry and wet edges. Background technique [0002] Agricultural drought refers to that during the growth and development of crops, due to insufficient precipitation, low soil moisture content and timely and appropriate irrigation of crops, the water supply cannot meet the normal water demand of crops, resulting in crop yield reduction. Agricultural drought is characterized by soil water content and plant growth state. It refers to a kind of agricultural meteorological disaster caused by long-term no rain in the agricultural growing season, resulting in atmospheric drought, soil water shortage, and inhibited crop growth and development, resulting in obvious production reduction or even crop failure. The main factors that reflect the degree of drought are: precipitation, soil water cont...
