Abstract: A three-dimensional shape data processor for processing data concerning a three-dimensional shape to be formed on a flat plate has a synthesis processing means (5 and 6) for performing synthesis processing such that three-dimensional shape data are partially superimposed on one another, and at an overlap portion, either one of the three-dimensional shape data is left as it is, while the other is erased, and an interpolation processing means (7) for performing interpolation processing by providing a predetermined interpolation region at a boundary between the three-dimensional shape data subjected to the synthesis processing. Interpolation is performed so that the height changes continuously between the three-dimensional shape data combined together through the interpolation region. An engraving apparatus cuts a flat plate immersed in a cutting fluid, thereby preventing cuttings from depositing on a cutting blade or the plate being engraved even in the case of a noble metal.

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.

Abstract: An automatic engraving system for automatically engraving the lateral contour of a person's face on one surface of a medal includes two industrial television cameras for three-dimensionally measuring the lateral contour of the person's face by using light beam or laser light beam, a computer for determining the lateral contour of the person's face by processing the dimensional data derived from measurements and at least one three-dimensional cutting machine for engraving on the medal the lateral contour of the person's face based on the processed date derived from the computer.
