Abstract
An illumination device has a light source unit, a lens unit, and a filter unit An imaging device receives object light, generated by the illumination light, from the measurement object at a predetermined observation solid angle, and pixels of the imaging device can each identify the different light wavelength ranges. A processing device includes an arithmetic unit configured to obtain a normal vector at each point of the measurement object corresponding to each pixel from inclusion relation between the plurality of solid angle regions, constituting the object light, and the predetermined observation solid angle, and a shape reconstruction unit configured to reconstruct the shape of the measurement object.
