METHOD AND SYSTEM FOR INSPECTING A SURFACE AREA FOR MATERIAL DEFECTS |
摘要 |
A method for inspecting a surface area of a known position for material defects by means of a camera assembly arranged on an unmanned and autonomously navigating aerial vehicle is disclosed, comprising: automatically flying the vehicle to the surface area from a launch site, wherein it can fly around obstacles by methods of automatic obstacle detection and avoidance; continuously measuring a relative position of the aerial vehicle with respect to the surface area with the aid of a position sensor; recording a sequence of images of the surface area, wherein, between the individual images, the aerial vehicle is moved along a flight path in relation to the surface area in such a way that the images of the sequence have in overlapping regions at least partially overlapping image details of the surface area; and composing the images of the sequence into an overall image of the surface area, in order to make it possible for the surface area to be inspected for defects and the location of defects to be ascertained on the basis of the overall image. |
