[0043] Please refer to image 3 , image 3 It is a flowchart of the method for avoiding obstacles provided by the first embodiment of the present invention. The method is applied to the UAV 100 and the auxiliary driving device 200 that are connected to each other in communication. The specific flow of the method for avoiding obstacles will be described in detail below. .

[0044] In step S111, the drone 100 obtains a panoramic image, and generates the panoramic image to the driving assistance device 200.

[0045] In this embodiment, the drone 100 can collect panoramic images around the drone 100 by setting two panoramic optical cameras. Specifically, the installation positions of the two panoramic optical cameras may be relative, so as to realize image acquisition without dead angles. In this embodiment, preferably, one of the panoramic optical cameras is set on the side of the propeller of the drone 100 for acquiring sky images, and the other panoramic optical camera is set on th...

[0065] Please refer to Figure 4 , Figure 4 It is a flowchart of a method for avoiding obstacles provided by the second embodiment of the present invention, and the method is applied to the drone 100 that is communicatively connected with the driving assistance device 200. The specific process of the method of avoiding obstacles is described in detail below.

[0066] In step S211, the drone 100 acquires a panoramic image, sends the panoramic image to the driving assistance device 200, and the driving assistance device 200 performs a visual scene analysis on the acquired panoramic image to obtain the scene and objects under the panoramic image. The scene around the flight path of the aircraft 100 performs obstacle recognition.

[0067] Specifically, after the drone 100 obtains a panoramic image through a panoramic optical camera, the data of the panoramic image is transmitted to the auxiliary driving device 200, the auxiliary driving device 200 receives the panoramic image obtained...

[0083] Please refer to Figure 5 , Figure 5 It is a block diagram of functional modules of a device 110 for avoiding obstacles according to the third embodiment of the present invention. The device is applied to the unmanned aerial vehicle 100 that is communicatively connected with the auxiliary driving device 200. The device includes: an acquisition module 1101, a receiving module 1102, a distance detection module 1103, and an evasion module 1104.

[0084] The acquisition module 1101 is used to acquire a panoramic image and send the panoramic image to the driving assistance device 200. The driving assistance device 200 performs visual scene analysis on the acquired panoramic image to obtain the scene and objects under the panoramic image, and compare all the images in the panoramic image. The scene around the flight path of the UAV 100 performs obstacle recognition.

[0085] The receiving module 1102 is configured to receive the obstacle orientation information sent by the driv...

Abstract

The invention discloses a method and a device for avoiding obstacles. The method and the device are applied to an unmanned aerial vehicle and auxiliary driving equipment which are in mutual communication connection. The method comprises the following steps of enabling the unmanned aerial vehicle to obtain a panoramic image, and sending the panoramic image to the auxiliary driving equipment; enabling the auxiliary driving equipment to receive the panoramic image, performing visual scene analysis on the panoramic image, and obtaining the scene and object in the panoramic image; identifying the obstacle in the surrounding scene of a flight path of the unmanned aerial vehicle in the panoramic image, and sending the azimuth information of the obstacle to the unmanned aerial vehicle when the obstacle exists; enabling the unmanned aerial vehicle to detect the distance on the azimuth of the obstacle, and obtaining the distance between the obstacle and the unmanned aerial vehicle; enabling the unmanned aerial vehicle to avoid the obstacle according to the azimuth of the obstacle and the distance between the obstacle and the unmanned aerial vehicle. By adopting the technical scheme, the method has the characteristic that the dynamic obstacle can be locked and avoided, so that the 720-degree protection function on the unmanned aerial vehicle is realized.

Description

Technical field [0001] The present invention relates to the field of drone control, in particular to a method and device for avoiding obstacles. Background technique [0002] The unmanned aircraft is abbreviated as "UAV" and the English abbreviation is "UAV". It is an unmanned aircraft operated by radio remote control equipment and self-provided program control devices. UAV is an unmanned aircraft with multiple rotor shafts. It is rotated by the electric motor on each shaft, which drives the rotor to generate lift and thrust. The UAV engine is designed around the fuselage of the aircraft. When any propeller is damaged, it will cause the fatal problem of the crash. [0003] Therefore, in order to realize the safe flight of the UAV, in the prior art, the assisted driving of the UAV mainly uses the gyroscope, GPS, airspeed head and other sensors to maintain the stability of the UAV flight attitude and the spatial position. Therefore, the unmanned driving of the UAV and the function...
