Abstract: PURPOSE:To measure the absolute three-dimensional coordinate of an objective body, by mounting one projection device and one observation device and forming a lattice like pattern to a projection surface and observing the image of the lattice pattern projected to the objective body. CONSTITUTION:A projection device 30 is equipped with a projection surface 31, for example, a slide film having a lattice like pattern 301 formed thereto and a light source irradiating the objective body 10 placed in the same three- dimensional coordinates system as the projection surface 31 through the projection surface 31. When the light source 32 lights, the pattern 301 is projected onto the surface of the body 10 to form a lattice like pattern image 101. The three-dimensional coordinates of the sampling point 10s on the lattice line image 10x on the body 10 constituting the pattern 101 can be determined by utilizing a fact that the points 10s is the intersecting point of the straight line ls of light emitted from the light source 32 and illuminating the points 10s and the straight line ms containing the specific point 22 of an observation device 20 and the point 10s. Therefore, the three-dimensional shape of the objective body is displayed on a display device by determining the coordinates of a large number of sampling points on said body.
