Title:
３次元形状計測システム
Document Type and Number:
Japanese Patent JP5663464
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To correctly calculate a three-dimensional shape of a target object by preventing multiple projection on the target object when using a plurality of mirror surfaces.SOLUTION: A studio device 10 has a bottom-open box shape having mirror surface plates 101 to 104 arranged in four sides and joined, and all or a part of the mirror surface plates are inclined to a top surface when viewed from the top surface side, and the studio device 10 is used with a target object on the bottom surface side. The inside of the studio device 10 is photographed by a photographing device in a state where a pattern image is projected on the inside of the studio device 10 by a projection device arranged on the top surface side, and a top surface shape of the target object placed in the studio device and shapes of front and back and right and left sides of the target object reflected on respective mirror surface plates are acquired as three-dimensional information from a photographed image, and an entirely peripheral three-dimensional image is created on the basis of the three-dimensional information. The mirror surface plates 101 to 104 arranged in four sides have polarizers 201 to 204 having mutually orthogonal transmission axes, on front surfaces of mirror surfaces facing each other. Thus, multiple projection on the target object due to retroreflection of reflected waves of a light source, from the projection device is prevented.
