THREE-DIMENSIONAL MEASURING INSTRUMENT AND THREE-DIMENSIONAL MEASURING METHOD

摘要

The invention provides a three-dimensional measuring apparatus that can efficiently analyze a three-dimensional image by simultaneously recording a circular streak image and a straight-line streak image at a measured point, even when a large number of circular streak images are present. A three-dimensional measuring apparatus 50 includes: a 3CCD camera (an imaging unit) 11 configured by CCDs of three primary colors; a cubic beam splitter 12 that combines optical images incident from plural routes; a mirror 14 that shifts an image focusing position of an optical image at a measured point 18 by a predetermined distance; a red filter (a coloring unit) 13 that applies a predetermined color to an optical image incident to a route of the beam splitter 12; a motor (not shown) that rotates the beam splitter 12 and the mirror 14 in a direction of an arrowhead 17; and a PC (not shown) that calculates a three-dimensional position of the measured point 18 based on the optical image recorded by a camera 11.
