Application of machine vision technology in water-saving irrigation of sugarcane and other economic crops

As substitute of human eyes,machine vision is safer,more stable and intellectualized technology for ac-curacy measurement and inspection. To provide guideline or theoretical basis for accurate and efficient water-sav-ing irrigation,the authors discuss new ways of efficient water-saving irrigation in five aspects including study ofmachine vision and crops growth water demand model,targeted pesticide spraying for sick crops,construction ofwater-fertilizer coupling of quantitative fertilization model,water retention characteristics of different soil,applica-tion of machine vision in water-saving irrigation equipment.
