Abstract: A three-dimensional shape measuring apparatus includes a stage that includes a translation stage part having a placement surface on which a measurement object is placed and capable of translating the placement surface; an illuminator that includes independently controllable and two-dimensionally-arranged projection devices, and illuminates the measurement object, which is placed on the stage, with measuring light having a predetermined projection pattern having alternating light-and-dark intervals; a photoreceptor that receives measuring light reflected by the measurement object illuminated by the illuminator, and to generate a projection pattern image; and a movement controller that controls the translational movement of the translation stage part by a moving pitch smaller than the minimum width of the projection pattern which can be projected on the stage by independently controlling the projection devices of the illuminator.

Abstract: CAD data, which can be directly used for a design drawing, can be easily created from geometric element following mesh data. Provided is a reverse engineering support apparatus that converts mesh data obtained by measuring a three-dimensional shape of a workpiece into CAD data and outputs the CAD data. The reverse engineering support apparatus includes: a data acquisition unit that acquires mesh data; an extraction unit that extracts geometric element data from the mesh data; a rounding unit that executes rounding on a characteristic value of the geometric element data extracted by the extraction unit; a conversion unit that converts the geometric element data subjected to the rounding into CAD data; and an output unit that outputs the CAD data.

Abstract: To enable even a less experienced user to easily perform highly reproducible reverse engineering. A reverse engineering system includes a scanner module and a conversion module. The scanner module includes a measurement condition setting unit, a scanner control unit that generates image data according to a measurement condition, a mesh data creation unit that creates mesh data based on measurement data of a workpiece, and a scanner output unit that outputs the mesh data to the conversion module. The conversion module includes a CAD conversion unit that converts the mesh data into CAD data according to a processing parameter calculated based on at least one of the measurement condition or the image data.
