Title:
SENSING DEVICE AND SENSING METHOD
Document Type and Number:
WIPO Patent Application WO/2024/029142
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide a sensing device and a sensing method that make it possible to accurately measure the three-dimensional shape of an object including a transparent material. To this end, a calculator 1 generates an image 35 on the basis of visual information of an object 30, extracts an area occupied by the object 30 as an object area 36 from the image 35, extracts distance information of an edge portion of the object 30 from distance information of the object 30 to generate edge distance information 37, generates a far-infrared image 41 corresponding to the object area 36 on the basis of far-infrared information of the object 30, controls a heating device 4 to heat the object 30, estimates partial surface shape information 44, 45 of the object 30 from the far-infrared images 41, 42 before and after the heating of the object 30, generates interpolated edge distance information 57 of the object 30 by interpolating the edge distance information 37 using the partial surface shape information 44, 45, and converts the interpolated edge distance information 57 to three-dimensional shape information and outputs the three-dimensional shape information.
