Space structure detection method and device for unmanned aerial vehicle

Abstract

The invention discloses a space structure detection method and device for an unmanned aerial vehicle. The detection method comprises the steps of starting assembled distance sensors in multiple directions; receiving distance sensing data sent by the distance sensors for calculating the distance between the unmanned aerial vehicle and peripheral surrounding obstacles; sending the distance sensing data to a control side so as to integrating the distance sensing data into a three-dimensional space structure. The invention further provides multifunctional control equipment for implementing the detection method. The invention provides a method for detecting the space structure when the unmanned aerial vehicle is in the flying state. The distance between the unmanned aerial vehicle and the peripheral obstacles can be detected out through the multiple distance sensors assembled on the unmanned aerial vehicle, and then the space structure is integrated according to the distance data. The method is applicable to detection of a toxic gas region and a dangerous region where workers cannot enter conveniently, so that personal safety can be ensured.

Description

technical field [0001] The present invention relates to the field of aviation science and technology, and more specifically, to a method and device for detecting a spatial structure by an unmanned aerial vehicle. Background technique [0002] Unmanned UAV, referred to as UAV, is an unmanned UAV controlled by remote control method and self-contained program control device. In order to maintain the balance of the body and complete work tasks, more and more sensors can be installed on the body of the drone. With the development of microelectronics technology, the integration of high-precision sensors on small drones has become a reality. At present, UAVs can achieve more and more functions, and have been widely used in aerial reconnaissance, surveillance, communication, anti-submarine, electronic jamming, etc. [0003] At present, UAV technology has been widely used in the detection of two-dimensional planes, such as terrain detection. A device applied to terrain tracking is ...

AI Technical Summary

Problems solved by technology

[0004] The above method can realize the detection of two-dimensional plane, but it cannot realize the detection of three-dimensional space structure

In the above scheme, two laser ranging modules are used to measure terrain parameters, and the detection range is limited to a single plane. It cannot detect upright objects or covered objects, and there is even the danger of hitting objects such as walls and cliffs during the flight. Its application is limited by the external environment, and the feasibility is not high
