SHAPE-MEASURING APPARATUS, MANUSCRIPT IMAGE-CORRECTING APPARATUS, AND PROJECTED IMAGE-CORRECTING APPARATUS

摘要

PROBLEM TO BE SOLVED: To accurately measure the shape of a subject by improving measuring accuracy caused by the resolution in quantity of light. SOLUTION: An illumination apparatus 110 applies a first discrete light stripe pattern to a parallax direction for connecting the arrangement position of an own illumination apparatus with that of a CCD 122, and a second light stripe pattern that has a different light intensity distribution from the first discrete light stripe pattern and is discrete to the parallax direction to a measuring region 151. The CCD 122 detects each reflection light of the first and second light stripe patterns that are reflected by the measuring region 151. A shape- calculating apparatus 130 obtains the shape of the measuring region 151 based on the ratio of the quantity of light in reflection light corresponding to the first and second light stripe patterns that are detected by the CCD 122 and the parallax based on the triangulation principle.
