Method and device for determining air route of unmanned plane

The embodiment of the invention provides a method and device for determining the air route of an unmanned plane, and the method comprises the steps: determining the land parcel information of an operation land parcel of the unmanned plane currently, wherein the land parcel information comprises reference air routes; obtaining the prediction resource information corresponding to the operation land parcel; obtaining the remaining resource information of the current unmanned plane; selecting a part of air routes from the reference air routes as the actual air routes according to the remaining resource information if the remaining resource information is less than the prediction resource information. According to the embodiment of the invention, the method can give comprehensive consideration to the land parcel information and the remaining resource information of the unmanned plane, enables the determined actual air routes to be more suitable for the actual condition of the unmanned plane, enables the planning o
