Path planning method and path planning equipment for spraying operation

The invention discloses a path planning method and path planning equipment for spraying operation. The path planning method for spraying operation comprises the steps of determining a to-be-sprayed operation area; obtaining range size parameters of the characteristic range of an unmanned aerial vehicle, wherein the range size parameters comprise one or more of a fuselage range, a working range ofan unmanned aerial vehicle power system and a spraying operation range; according to the range size parameters, determining waypoints for the unmanned aerial vehicle to execute spraying operation on the to-be-sprayed operation area, wherein, when the unmanned aerial vehicle conducts spraying operation on an air route indicated by the waypoints, the characteristic range of the unmanned aerial vehicle does not exceed the boundary of the to-be-sprayed operation area, and therefore it can be seen that by means of the mode, the boundary safety problem caused when the unmanned aerial vehicle executes spraying operation in a
