PURPOSE:To replicate a stereoscopic image, by a method wherein information signal of each sectional shape of a stereoscopic image obtained as a point line in a two-dimensional rectangular coordinate system is converted to a two-dimensional cylindrical coordinate system to be memorized, a base is turned by angle information to cut the contour on radius information and plate materials thus obtained are laminated. CONSTITUTION:A laser light of a light source 2 is made a slit light 2b to irradiated the circumference of one section element of an object 4, raised to be photographed with a camera 1 and then, a 2-D image is measured 3a to memorize 3b the sectional shape of the object 4 as point line in a 2-D rectangular coordinate system. The sectional shape is converted 5a to a cylindrical coordinate system to be memorized and angle information is read out 6a to drive 11 a rotary platform 10, radius information is read-out 6b to drive 12 a linear slide base 19 to the center and a planar material 18 on the platform 10 is melt down with a vertical heating line 14 between parallel bars 19a and 19b of the slide base 19. The formed plates thus obtained are laminated and welded in the order of measurement, thereby enabling the replication of the object 4 in a massproduction. |
