Title:
AERIAL TYPE INSPECTION DEVICE AND INSPECTION METHOD
Document Type and Number:
Japanese Patent JP2017075863
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide an aerial type inspection device and inspection method that allow use of downsized unmanned aircrafts to conduct an inspection while controlling an angle and distance relative to a plane-like inspection object.SOLUTION: An aerial type inspection device 1 comprises: a downsized unmanned aircraft 91 that includes a plurality of rotary wings 911 and a control unit; an inspection unit 30 that is attached to the downsized unmanned aircraft 91, and contactlessly inspects a state of an object surface; and a range-finder unit 20 that measures an object distance serving as a distance to the object surface with respect to a plurality of measurement directions. The control unit comprises estimation means that estimates a facing surface parameter composed of an angle with respect to the object surface of the inspection unit 30 and the distance from the object surface at the angle on the basis of the object distance measured by the range-finder unit 20. The aerial type inspection device 1 is configured to: move the downsized unmanned aircraft 91 along the object surface as fixedly maintaining the facing surface parameter with respect to the object surface of the inspection unit 30 on the basis of the estimation result; and conduct inspection by the inspection unit 30 with respect to a plurality of locations of the object surface.SELECTED DRAWING: Figure 1
