1. A flight route splicing method, comprising:
obtaining a first flight route and a second flight route of an unmanned aerial vehicle;
obtaining a flight height of a highest waypoint having a greatest flight height in the first flight route and the second flight route and ground elevations of a series of waypoints between a termination waypoint of the first flight route and a start waypoint of the second flight route;
obtaining a flight height of an intermediate flight route according to the flight height of the highest waypoint and the ground elevations of the series of waypoints between the termination waypoint and the start waypoint, wherein the intermediate flight route is used for connecting the first flight route and the second flight route and is located between the first flight route and the second flight route;
determining the intermediate flight route according to first geographic location information of the termination waypoint, second geographic location information of the start waypoint, and the flight height of the intermediate flight route; and
splicing the first flight route and the second flight route according to the intermediate flight route to generate a spliced flight route.
