Patent ID: 7495776

Claim:
A three-dimensional measuring system for measuring a three-dimensional shape of a measurement object in a noncontact manner, the system comprising: a first storage portion for storing arrangement information of the measurement object; a second storage portion for storing design shape information of the measurement object; a third storage portion for storing specifics information about one or more three-dimensional measuring devices; a determining portion for determining an unmeasurable part that cannot be measured by the one or more three-dimensional measuring devices about a surface shape of the measurement object in accordance with the stored arrangement information, the stored design shape information and the stored specifics information by determining at least one of the three following conditions is met: an amount of light reflected from a part to be measured of the measurement object does not fall within a first predetermined range, an interference object obscures the part to be measured of the measurement object from the three-dimensional measuring system, and tolerance of the part to be measured of the measurement object does not fall within a second predetermined range; and an output portion for outputting the determined unmeasurable part.
