Title:
MEASURING SYSTEM AND MEASURING METHOD
Document Type and Number:
WIPO Patent Application WO/2017/002831
Kind Code:
A1
Abstract:
This measuring system S is provided with: a slit light irradiation device 2 that emits a plurality of slit laser beams 23a to 23d in the shape of a slit to a tubular body 9; a dot light irradiation device 3 that emits a plurality of dot laser beams in the shape of a dot to the tubular body 9, each dot laser beam having a predetermined positional relationship with each of the slit laser beams 23a to 23d; an imaging device 4 that images a plurality of bright lines L1 to L4 that appear on the surface of the tubular body 9 and a plurality of bright spots D that appear on the surface of the tubular body 9 to generate an image thereof; an identification unit 152 that compares the generated image with a reference image representing predetermined positional relationships between the bright lines L1 to L4 and the bright spots D to identify correspondences between the bright lines L1 to L4 in the generated image and the slit laser beams 23a to 23d; and an acquisition unit 153 that acquires three-dimensional coordinates of the bright lines L1 to L4 on the basis of two-dimensional coordinates of the bright lines L1 to L4 in the generated image and the correspondences identified by the identification unit 152.
