DEVICE, METHOD AND PROGRAM FOR DETERMINATION OF THREE-DIMENSIONAL OBJECT

摘要

PROBLEM TO BE SOLVED: To precisely determine whether an object included in an acquired image is a three-dimensional object.

SOLUTION: A three-dimensional object determining device includes: a detection unit 2 which detects a plurality of feature points of an object included in acquired image data; a pattern normalizing unit 5 which generates a normalization pattern provided by normalizing the feature points by a three-dimensional model; an estimation unit 6 which estimates the illuminating direction of light applied on the object in the image data from the three-dimensional model and the normalization pattern; and a determination unit 7 which determines whether the object in the image data is a three-dimensional object by using the illuminating direction.
