Detailed Description
The utility model is further described below with reference to the accompanying drawings.
The unmanned aerial vehicle landing auxiliary device comprises 1 laser indicating module and 1 biaxial stable cradle head for stabilizing the laser indicating module. The laser indicating module projects a laser beam downwards to form an indicating pattern for indicating the ground projection position of the unmanned aerial vehicle.
As shown in fig. 1, the unmanned aerial vehicle equipped with the unmanned aerial vehicle landing auxiliary device comprises an unmanned aerial vehicle body (1) internally provided with a flight control system, a laser indication module (2) is connected to the bottom of the unmanned aerial vehicle (1) through a two-axis stable cradle head (3), and two balanced directions of the two-axis stable cradle head (3) are pitching directions and rolling directions respectively, so that the laser indication module (2) always keeps vertical downward when the unmanned aerial vehicle flies, and the indication pattern is prevented from drifting continuously along with the shaking of the unmanned aerial vehicle, so that the unmanned aerial vehicle position can be accurately indicated.
As shown in fig. 2, the laser indication module (2) is electrically connected with the power supply through a relay, a driving interface of the relay is connected with a signal output port of the flight control system, and the flight control system outputs a high-level driving instruction to drive the relay so as to conduct the power supply, thereby starting the laser indication module (2). The flight control system designates output driving instructions to enable the laser indication module (2) to project indication patterns when the flight height of the unmanned aerial vehicle (1) is reduced or when the flight height of the unmanned aerial vehicle (1) is lower than 25 m.
The laser light indication module (2) can be provided with a plurality of laser light emitting ends; when the number of the laser emission ends is more than 1, the indication patterns projected by different laser emission ends are different, and other text contents and the like are also included.
