Because of the sugar cane very labor-intensive manual spraying of pesticides,and the previous motor Sprayer low degree of automation,spraying insecticidal effect is not ideal. The system uses the water level sensors,weight detectors and STC89C516 MCU intelligent pesticides on the water; Using the CMOS camera,the quality of real -time monitoring of the spraying in the liquid by adding natural pigments,and the appropriate use of improved BP neural network pattern recognition,to improve the quality of recognit...
