Document Type and Number:
WIPO Patent Application WO/2023/038187
Kind Code:
A1
Abstract:
An embodiment may provide an unmanned aerial vehicle employing a LiDAR sensor for measuring a crack thickness of a structure, the unmanned aerial vehicle comprising: a body; a camera location control module connected to the body; a camera installed in the camera location control module; a LiDAR location control module connected to the body: and a LiDAR sensor which is installed in the LiDAR location control module and detects information of a distance to an inspection point to determine a size of a crack of an inspection structure detected in a photographed image detected by the camera, wherein the camera is changed in photographing location by the camera location control module and the LiDAR sensor is changed in location by the LiDAR location control module.
