Embodiment Construction

[0049] The present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.

[0050] In order to make it easier for readers to understand the present invention, firstly, the devices arranged around the drone are described, wherein, the drone is surrounded by ultrasonic distance measuring devices, laser distance measuring devices and binocular vision distance measuring devices. Therefore, ultrasonic distance measuring There are multiple devices, laser ranging devices and binocular vision ranging devices, and the corresponding detection orientations of each ultrasonic ranging device, laser ranging device and binocular vision ranging device can be defined in advance, for example: no one The ultrasonic ranging device, laser ranging device and binocular vision ranging device on the left side of the drone correspond to detecting whether there are obstacles in the space environment on the left side of the drone, and the ultrasonic rang...

Abstract

The invention discloses a UAV (Unmanned Aerial Vehicle) automatic obstacle avoidance method and system. A UAV is equipped with an ultrasonic wave ranging device, a binocular vision ranging device and a laser ranging device. The method includes detecting a space environment of the UAV, obtaining the environmental parameters of the space environment; determining the environment type of the space environment and collecting the environment images of the space environment, determining which ranging device is to be used for detecting obstacles around the UAV and determining the locations of the obstacles and the distances between the obstacles and the UAV. Therefore, UAV automatic obstacle avoidance is realized. By adopting the above method, the appropriate ranging device can be started for detecting the obstacles according to the different environment types and the environment images of the space environment, advantages of each ranging device can be fully played and shortcomings of each ranging device can be avoided, obstacle detecting accuracy and efficiency can be improved and therefore the UAV automatic obstacle avoidancesuccess rate can be improved.

Description

technical field [0001] The invention relates to the technical field of drones, in particular to a method and system for automatic obstacle avoidance of drones. Background technique [0002] Unmanned aircraft, referred to as "UAV", refers to an unmanned aircraft that is controlled by radio remote control equipment and its own program control device. [0003] With the development of science and technology, drones are becoming more and more advanced and cheaper, and because drones have the advantages of no risk of casualties, strong survivability, good maneuverability, and convenient use, drones are used in It has been widely used in civil fields such as aerial photography, geological survey, high-voltage transmission line inspection, oil field pipeline inspection, highway management, forest fire prevention inspection, poisonous gas investigation, anti-drug and emergency rescue, ambulance and so on. For example: In the field of film and television drama shooting, drones are eq...
