Embodiment 1

[0123] figure 1 It is a flow chart of the steps of a UAV forced landing method provided by Embodiment 1 of the present invention. This embodiment of the present invention is applicable to the situation of UAV emergency landing. Aircraft forced landing device to implement, the device can be implemented in the form of software and / or hardware, and integrated in the UAV, such as figure 1 As shown, the method specifically includes the following steps:

[0124] S101. During the flight of the UAV, determine the forced landing area.

[0125] In practical applications, the UAV is equipped with a depth sensor and a radar. Both the depth sensor and the radar can face the bottom of the UAV. The depth sensor has a certain viewing angle, which can obtain depth images for the area that can be covered on the ground.

[0126] Optionally, the depth of field sensor can be a camera, and the camera can be one of a binocular camera, a monocular camera, and a multi-eye camera, and a depth image i...

Embodiment 2

Abstract

The embodiment of the invention provides an unmanned aerial vehicle forced landing method and device, an unmanned aerial vehicle and a storage medium. The method comprises the following steps: determining a forced landing area in the flight process of the unmanned aerial vehicle; acquiring position information of the forced landing area; storing the position information in a memory; when a forcedlanding event is detected, reading the position information of each forced landing area from the memory; determining a target forced landing area according to the position information of each forced landing area; and controlling the unmanned aerial vehicle to forcibly land in the target forced landing area. By controlling the unmanned aerial vehicle to store the determined position information ofthe forced landing area in the flight process, the problem that when the unmanned aerial vehicle needs forced landing, a large amount of time needs to be spent in searching for the area where forced landing can be achieved, and consequently the unmanned aerial vehicle cannot land in time is solved, and the retention time of the unmanned aerial vehicle in air in emergency is shortened; therefore, the unmanned aerial vehicle can be forced to land in a proper area in time, safe forced landing of the unmanned aerial vehicle is guaranteed, and damage to the unmanned aerial vehicle during forced landing is reduced.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of drones, and in particular to a method for forced landing of a drone, a device for forced landing of a drone, a drone and a storage medium. Background technique [0002] With the gradual maturity of UAV technology, UAVs have been widely used in many fields. For example, UAVs can perform flight operations such as surveying and mapping, plant protection, exploration, and aerial photography according to pre-planned routes. [0003] In the prior art, before the unmanned aerial vehicle takes off, a landing point has been set in the pre-planned route, and the unmanned aerial vehicle returns to the landing point to land after completing the flight mission, or lands on the spot after performing the flying mission. [0004] However, during the flight of the UAV, it is possible to encounter an emergency and need to make a forced landing, for example, when the UAV has insufficient power, mec...
