Generation method and device of flight line of aircraft and terminal equipment

The invention provides a generation method and a device of a flight line of an aircraft, as well as terminal equipment. The method comprises the steps of determining at least three position coordinate points in a target area to be flown, determining a flying boundary of the target area according to a position relationship among the at least three position coordinate points, and generating the flight line of the aircraft according to the flying boundary and width between adjacent route segments in the same direction in the target area. According to the technical scheme, a manner of manually clicking an electronic map to determine the at least three coordinate position points in the target area can be avoided; a manual operating error is eliminated; the flying boundary of the target area is more accurate; and a flying monitoring effect of the aircraft in the whole target area can be further improved.
