APPARATUS FOR OBTAINING IMAGE OF 3-DIMENSIONAL OBJECT

摘要

A three dimensional image acquiring system using a concave mirror removing shadow according to the contour of the surface of a product and securing the quantity of lightness for the image acquisition is provided to remove the brightness of the global image of screen brightness using the lens of the small caliber. A light source(21) radiates light by using the concave mirror of the spherical surface. A condensing lens(22) radiates light from the light source. A projection grating(23) transmits the light which is condensed through the condensing lens. A projection lens(24) radiates the outgoing light from the projection to parallel beam. A concave mirror(25) reflects the collimated light of the projecting lens. A CCD camera(27) obtains the reflection light reflected from a measurement object(26). It is condensed through the condensing lens and the outgoing light coming out from the light source is income to the projection grating.
