The invention relates to the field of
plant protection unmanned planes, and provides an adaptive operation method for a
plant protection unmanned plane based on an
expert system. The method comprisesthe steps: (1), collecting a
crop image of an operation area through an airborne camera; (2), performing
image segmentation and
feature extraction of the collected image, and analyzing the
crop species, the
weed species, the pest species and the severity thereof; 3), comparing the data with an
expert system database in an airborne
control system, and obtaining the amount of liquid
medicine to be sprayed in a target area; (4), enabling an airborne liquid spraying mechanism to adaptively spray the liquid
medicine according to the index of the amount of sprayed
medicine given by the airborne
expert system database. The method is advantageous in adaptively carrying out the
plant protection spraying operation according to the index of the amount of sprayed medicine given by the airborne expertsystem in real time and the
crop species, the
weed species, the pest species and the severity thereof in the operation area, effectively improving the
pesticide spraying effect and
pesticide utilization rate, avoiding the spraying leakage or repeated spraying in the operation area, needing no manual intervention in the whole process, and greatly improving the intelligentization degree of the plantprotection operation process.
