Embodiment Construction

[0027] In order to facilitate the understanding of those skilled in the art, the present invention will be further described below in conjunction with the accompanying drawings.

[0028] as attached figure 1 As shown, an automatic return laser positioning system for unmanned aerial vehicles, including a main control module arranged on the unmanned aerial vehicle body 1, a laser locator 3, and a laser positioning system arranged at the return point of the unmanned aerial vehicle for the laser positioning The laser recognition instrument 5 that is identified and positioned by the instrument 3, the main control module is connected with the laser locator 3;

[0029] The main control module is used to issue a control instruction for emitting laser to the laser locator 3 when the UAV returns to the home and hovers over the vicinity of the return point; the laser locator 3 receives the control instruction for emitting laser Send out the laser beam 4 after the instruction, and identi...

Abstract

The invention discloses an automatic return flight laser positioning system for an unmanned plane. The system comprises a master control module, a laser position indicator and a photosensitive sensor arranged on the body of the unmanned plane, and a laser identification instrument which is positioned on a return point of the unmanned plane and allows the laser position indicator to identify and position, and the laser position indicator and the photosensitive sensor are connected with the master control module. The automatic return flight laser positioning system has the advantages of accurate return flight landing positioning, high automation level and high landing safety, allows the unmanned plane to accurately and safely land on the position of a return flight point under automatic return flight, out of control return flight and low-light return flight modes and effectively prevents casualties and loss of the unmanned plane.

Description

technical field [0001] The invention relates to the technical field of unmanned aerial vehicles, in particular to an automatic return-to-home laser positioning system for unmanned aerial vehicles and an unmanned aerial vehicle equipped with the laser positioning system. Background technique [0002] At present, the existing automatic return system for drones only relies on GPS and the latitude and longitude of the take-off point recorded by the flight controller to return. The landing process is: the drone returns to the sky above the return point, hovers for a few seconds, and then lands. Therefore, the accuracy of the drone returning to the home point (that is, the take-off point recorded before the drone took off) is extremely low, with an error of two to three meters, and sometimes it even returns directly above the driver, requiring the driver to constantly adjust The air position of the UAV is used to allow the UAV to land safely in a certain area, which cannot achieve...
