Abstract:
1. A three-dimensional shape measuring system, comprising: a measuring unit having a three-dimensional measurement range and adapted to measure a three-dimensional shape of a measurement object in a noncontact manner; a measurement range shifting unit for shifting the position of the measurement range of the measuring unit; a shape calculating unit programmed to calculate an overall three-dimensional shape of the measurement object from a plurality of measurement data obtained by shifting the position of the measurement range relative to the measurement object; and a judging unit programmed to set a judgment area in a specified peripheral part of the measurement range and judge the presence or absence of any unmeasured area of the measurement object outside the measurement range based on measurement data corresponding to the judgment area, wherein the measurement range shifting unit is adapted to shift the position of the measurement range in a direction toward the unmeasured area when the presence of an unmeasured area is judged by the judging unit.
