Embodiment Construction

[0056] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0057] figure 1 A method for automatic monitoring of plant water stress state according to an embodiment of the present invention is shown, including:

[0058] S11. Acquire the infrared image, the visible light image of the plant, and the soil moisture content information of the corresponding plant. In this step, it should be noted that when collecting information, infrared images, visible light images of plants and soil moisture content information of corresponding plants can be collected through the set infrared collectors, visible light collectors and moisture collectors. Wherein, the infrared collector and the visible light collector can be an infrared camera and a v...

Abstract

The invention provides a plant water stressed state automatic monitoring method and a plant water stressed state automatic monitoring system. The plant water stressed state automatic monitoring method includes the following steps that: the infrared image and visible light image of plants and soil moisture content information of the corresponding plants are obtained; image fusion information is obtained according to the infrared image and the visible light image; the water stressed state information of the plants is obtained according to the image fusion information and the soil moisture content information; and corresponding instruction information is emitted according to the water stressed state information of the plants, so that a water replenishment device can be made to enter a corresponding working state. According to the plant water stressed state automatic monitoring method and the plant water stressed state automatic monitoring system of the invention, the infrared image and the visible light image are obtained through an infrared camera and a visible light camera; the temperature information of a plant area is obtained; corresponding measures are taken according to the temperature information; and therefore, problems in on-line automatic fusion of an infrared image and a visible light image and automatic identification of a plant area on the infrared image can be solved, a plant canopy temperature region can be obtained, irrigation time of the plants can be accurately judged, and the plants can be prevented from being damaged.

Description

technical field [0001] The invention relates to the technical field of plant environment monitoring, in particular to an automatic monitoring method and system for plant water stress state. Background technique [0002] The shortage of water resources has become the primary factor restricting agricultural development. The development of water-saving agriculture and the comprehensive improvement of agricultural water use efficiency and benefits are the inevitable choices for sustainable agricultural development. [0003] In academia and engineering fields, a lot of related research and applications have been done on the automatic monitoring and diagnosis of plant water requirements. The solutions are currently mainly concentrated in the following aspects: [0004] (1) Plant water stress based on visible light images. [0005] (2) Monitor the water status of plants based on the canopy temperature, and the collection of canopy temperature requires infrared equipment to collect...
