Document Type and Number:
WIPO Patent Application WO/2019/163977
Kind Code:
A1
Abstract:
This weld operation measurement system comprises: a light irradiation unit which irradiates light; a 3-dimensional coordinate measurement unit which measures light reflected from a marker attached to a workpiece or a torch, the marker reflecting the irradiating light, and calculates 3-dimensional coordinate data of the workpiece and the torch; and a computing unit which, on the basis of 3-dimensional figure data and 3-dimensional coordinate data of the workpiece that have been input, obtains the coordinates of the shape of the workpiece, and generates coordinate data of the shape of the workpiece.
