Abstract
A three-dimensional scanner according to the present invention comprises: a camera arranged to receive incident light; an optical projector which is arranged on one side of the camera and irradiates light to an object; and a polarization filter which is spaced a certain set distance from the front surface of the camera, wherein the polarization filter is formed to be inclined by a certain set angle with respect to a plane that is perpendicular to an optical path of the light irradiated from the optical projector, so that at least some of the light irradiated from the optical projector passes through the polarization filter and the remaining light is reflected by the surface of the polarization filter and proceeds to outside of the lens of the camera.
