Crop irrigation system combined with computer vision and multi-sensor

The invention relates to the fields of image processing technology, the sensor technology and the water-saving irrigation, disclosing a crop irrigation system combined with computer vision and multi-sensor, wherein the technology adopted by the invention is non-destructive crop water-lacking detection combined with computer vision and multi-sensor; the system comprises the steps of obtaining and dividing a crop image, and extracting characteristic parameters; computing the characteristic parameters according to a growth data model; and then combining sensor data of a soil water potential sensor, a temperature and humidity sensor and the like, finally, finishing judgment by a genetic neural network, and controlling a single chip to drive an electromagnetic valve according to a judgment result to finish crop irrigation. The system can obtain water requirement information of crops immediately, achieve accurate irrigation immediately, and improve the utilization rate of water resource. The system has good practicability and can be applied to crop plantation areas such as a greenhouse, a farmland, a nursery garden and the like.
