ABSTRACT:
The present invention provides a three-dimensional processing device that can measure three-dimensionally the contour of a person's face including hair by laser beams without necessity for the measured person to move or to fit into the specific line for measuring. In order to fix a person in a predetermined position, a positioning means, for example, a backboard 10 is fixed. Positioning is performed by the person leaning against the backboard 10 or by providing a concave part 13 on the backboard 10 and fitting the person's shoulder into the concave part 13. A laser scanner 20 is installed on a scanner stand 22 so that it is possible to move it forward, backward, up, down, left and right. Further, it is possible to distinguish the backboard 10 from hair from which laser beams are not reflected by making the backboard 10 black or almost black so that it is possible to measure a shape by reflection when the laser beams are directed onto the surfaces.
