Road green belt automatic irrigation method and system based on image processing

The invention provides a road green belt automatic irrigation method and system based on image processing, and the method comprises the steps: an image collection step: carrying out the photographing of an image on an irrigation vehicle, and capturing a camera image through an upper computer; an image processing step: extracting green belt plant color features in the image, and sequentially carrying out image binaryzation and Gaussian blur noise reduction processing; a target area identification step: judging whether a target area exists in the processed image, if not, returning to the image acquisition step, and if yes, entering a target area size step; a target area size step: judging whether the size of the target area is greater than or equal to 100000 pixels; and an execution step: after the size of the target area is judged, driving an irrigation vehicle to perform irrigation in a corresponding mode through high electric frequency, and outputting the irrigation condition in real time by a management int
