1. An irrigation system based on computer vision monitoring, comprising a collector, an analyzer, a controller, irrigation equipment, and detection platforms;
wherein the detection platforms are installed in an irrigation area, a distance between the detection platforms is 5 m, and a height of each of the detection platforms is 3 m;
wherein the collector comprises weather sensors, monitoring sensors, plant information sensors, and soil sensors; the weather sensors are configured to collect weather information and transmit the weather information to the analyzer and are respectively arranged in positions of 1.5 m from the detection platforms; the soil sensors are configured to collect soil moisture information and transmit the soil moisture information to the analyzer; the monitoring sensors are configured to collect plant images and transmit the plant images to the analyzer, the monitoring sensors comprise cameras, and the cameras are installed at 2.8 m above the detection platforms; and the plant information sensors are configured to collect plant transpiration rates and plant leaf thicknesses;
wherein the analyzer is configured to: use an Euler video amplification method perform preprocessing, feature extraction, and type identification on the plant images to obtain a plant type, stem deformations, leaf areas and leaf colors; obtain leaf water potentials and leaf water content information according to the leaf colors, the leaf areas and the leaf thicknesses; obtain a plant growth state according to the leaf water potentials, the leaf water content information, the stem deformations and the plant transpiration rates; determine an irrigation scheme according to the weather information, the soil moisture information, the plant type, the plant growth state, and a preset irrigation rule; and transmit the irrigation scheme to the controller; and
wherein the controller is configured to regulate the irrigation equipment according to the irrigation scheme.
