Three-dimensional shape measuring apparatus, three-dimensional shape measurement additional device and the three-dimensional shape measuring method

摘要

PROBLEM TO BE SOLVED: To derive a three-dimensional shape of a measured object with high accuracy and reliability without influencing the visibility of the measured object and work efficiency for a person while ensuring continuity of illumination light.;SOLUTION: A three-dimensional shape measuring apparatus 110 comprises: a projection light source 150 which projects light of a specific color onto a measured object 102; a light receiving element 160 which receives reflected light of the specific color in reflected light reflected by the measured object and forms projection images; a signal generating unit 170 which generates a binarized control signal; an illumination controlling unit 162 which turns off an illumination device 120a which emits light including the specific color while the control signal indicates a first state, among a plurality of illumination devices 120a, 120b and 120c that emit illumination light to the measured object; a projection image formation controlling unit 172 which makes the light receiving element form projection images while the control signal indicates the first state; and a three-dimensional shape deriving unit 176 which derives the three-dimensional shape of the measured object based on the projection images formed by the light receiving element.;COPYRIGHT: (C)2012,JPO&INPIT
