METHOD FOR PRODUCING ARTICLE AND METHOD FOR MEASURING THREE-DIMENSIONAL SHAPE

摘要

PROBLEM TO BE SOLVED: To provide a method for measuring a three-dimensional shape of the measured face without lack by making the measured face hard to regularly reflect a light-cut image and also hard to lack the light-cut image even when the surface of the measured face possessed by an object includes a mirror plane.SOLUTION: In a production of a cylindrical container, a cylindrical container-shaped object 1020 having a surface including a mirror plane is prepared. The measured face including the mirror plane is selected from the surface. The mirror plane is excluded from the measured face including the mirror plane. A three-dimensional shape possessed by the measured face excluding the mirror plane therefrom is measured by diffused reflection light using a light cut method. It is determined whether or not the measured there-dimensional shape meets a condition. A cylindrical container is obtained from the cylindrical container-shaped object having the measured face with the three-dimensional shape which is determined to meet the condition.SELECTED DRAWING: Figure 1
