Title:
三次元計測装置
Document Type and Number:
Japanese Patent JP7276166
Kind Code:
B2
Abstract:
To provide a three-dimensional measuring device which can perform three-dimensional measurement and two-dimensional image acquisition by one session of photographing.SOLUTION: The three-dimensional measuring device comprises: a photographic image acquisition unit for acquiring the luminance value of a photographic image in which the state of a synthetic stripe pattern image being projected to a measurement object is photographed by a camera, the luminance value of the photographic image being available for each color pixel corresponding to each of the plurality of color filters of the camera; a phase calculation unit for calculating the phase of the luminance value for each pixel on the basis of the luminance value of the photographic image by color pixel; a coordinate determination unit for determining the three-dimensional coordinates of the measurement object on the basis of the phase calculated by the phase calculation unit; a projection luminance determination unit (S22) for determining, on the basis of the phase by pixel having been calculated by the phase calculation unit, a projection luminance If by color pixel of the synthetic stripe pattern image projected onto the measurement object; and a correction unit (S24) for performing correction of multiplying a luminance value Ib of a photographic image by color pixel by a correction coefficient for setting the projection luminance value to a preset given luminance value and thereby generating a two-dimensional image.SELECTED DRAWING: Figure 7
