Title:
THREE-DIMENSIONAL MEASURING DEVICE, AND THREE-DIMENSIONAL MEASURING METHOD
Document Type and Number:
WIPO Patent Application WO/2021/177236
Kind Code:
A1
Abstract:
The objective of the present invention is to appropriately set a distance range for calculating a gradation degree, in accordance with the height of a workpiece. This three-dimensional measuring device is provided with: a three-dimensional sensor which images a workpiece to acquire three-dimensional information; a setting unit which, on the basis of the acquired three-dimensional information, sets a reference position serving as a height direction reference in the workpiece, and a height direction margin, relative to the reference position, for a gradation degree of a gradation image, and sets a distance range corresponding to the gradation degree of the gradation image; an image converting unit which converts the acquired three-dimensional information into the gradation image on the basis of the distance range; and a detecting unit which employs the gradation image to obtain, three-dimensionally, the shape and/or the position and attitude of the workpiece.
