Plant protection unmanned aerial vehicle medicament spraying optimization method and device based on thermal infrared identification

The invention discloses a plant protection unmanned aerial vehicle medicament spraying optimization method based on thermal infrared identification. The method comprises the following steps: acquiringa thermal infrared image of the vegetation through an additionally-mounted thermal infrared image acquisition module, calculating the spraying condition of the vegetation according to the thermal infrared image of the vegetation, and adaptively adjusting the flight of the unmanned aerial vehicle according to the spraying condition of the vegetation. The invention further discloses a device usingthe plant protection unmanned aerial vehicle medicament spraying optimization method based on thermal infrared identification. The flight of the unmanned aerial vehicle is fed back and adjusted by judging the spraying condition of the medicament in real time, so that the phenomenon that a medicament is repeatedly sprayed and missed under the influence of wind power is avoided, and the operation effect is further improved.
