THREE-DIMENSIONAL SHAPE MEASURING DEVICE, INTEGRATED CIRCUIT, AND METHOD

摘要

A three-dimensional shape measurement can be performed with simple processing and regardless of whether an object moves or not.  A photographing unit (103) obtains a photographed image (I) in which both the real image (I2) of an object (113R) and a mirror surface (101) are photographed.  A light amount change unit (63a) changes the light amount of a virtual image (I1).  In a photographed image (Ia) when the light amount is changed and a photographed image (Ib) when the light amount is not changed, an image separation unit (imaging separation unit (104)) specifies, as a virtual image (Ib1), an image in a region (R1) where the light amount differs and specifies, as a real image (Ib2), an image in a region (R2) where the light amount is the same.  A three-dimensional shape is reconstructed from the specified real image and the like.
