THREE-DIMENSIONAL MEASUREMENT DEVICE FOR LINEAR OBJECT AND THREE-DIMENSIONAL MEASUREMENT METHOD FOR LINEAR OBJECT

Document Type and Number:

WIPO Patent Application WO/2019/188198

Kind Code:

A1

Abstract:

This three-dimensional measurement device for a linear object comprises: a stereo camera (11) that images a linear object; a transmission-light emission member (50) positioned opposite the stereo camera (11) with the linear object therebetween; and an operation unit that acquires the three-dimensional shape of the linear object. The stereo camera (11) acquires a transmission-light image of the linear object onto which light from the transmission-light emission member (50) has been emitted, and the operation unit acquires the three-dimensional shape of the linear object on the basis of the transmission-light image.
