Abstract
A three-dimensional measurement device includes: a projector including: a light source that emits a predetermined light; a grid that converts the light from the light source into a predetermined striped pattern; and a driver that moves the grid, and the projector projecting the striped pattern onto a measurement object; an imaging device that takes an image of the measurement object on which the striped pattern is projected; and a controller that: controls the projector and the imaging device to obtain a plurality of image data having different light intensity distributions; executes three-dimensional measurement of the measurement object by phase shifting based on the image data having different light intensity distributions; and obtains each of the image data among the image data having different light intensity distributions.
