An information converting system includes: a database (300) in which attribute
data including three-dimensional shape data of parts modeled on various objects
and identification codes are registered; a comparison part generating unit (400)
for generating part information for comparison from the attribute data for each
of the parts; an input unit (100) for obtaining an input image including
an object image; a comparison information generating unit (200) for performing
an imaging process on the input image to thereby generate image information for
comparison in which information of the object image is not clipped; and a specifying
unit (500) for retrieving a part corresponding to the part information for
comparison from the image information for comparison, recognizing the corresponding
portion in the image information for comparison as an object image, and specifying
a part having the part information for comparison as a part corresponding to the
object image.
