Abstract
The invention provides a 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 measuring apparatus includes: a 3CCD camera; a cubic beam splitter that combines optical images incident from plural routes; a mirror that shifts an image focusing position of an optical image at a measured point by a predetermined distance; a coloring unit that applies a predetermined color to an optical image incident to a route of the beam splitter; a motor that rotates the beam splitter and the mirror in a direction of an arrowhead; and a PC that calculates a three-dimensional position of the measured point based on the optical image recorded by a camera.
