Abstract: A free curved surface and an analytic curved surface can be generated as intended by a user with a simple operation. A reverse engineering support apparatus includes: a shape attribute setting unit that sets a shape attribute to a polygon included in mesh data; a region specifying unit that specifies a region included in the mesh data based on a shape attribute; a data conversion unit that converts a polygon included in the specified region into surface data based on the shape attribute and converts a polygon not included in the region into surface data of a free curved surface; and an output unit that outputs pieces of the surface data created by the data conversion unit as CAD data.

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: A reverse engineering support apparatus, includes: a data acquisition unit that acquires the mesh data; a reception unit that receives an input of a designated point on the mesh data; an extraction unit that extracts a plane candidate based on the designated point from the mesh data; a plane determination unit that creates a plane constituting a polyhedron based on the plane candidate; and a polyhedron creation unit that creates the polyhedron including the plane created by the plane determination unit. The reception unit can further receive designation of a constraint condition indicating a position and an attitude with respect to another surface or a position and an attitude in a predetermined coordinate system for each surface of the polyhedron, and the plane determination unit creates the plane constituting the polyhedron based on the plane candidate and the constraint condition.

Abstract: When acquiring a navigation image, to make it possible to set conditions the same as conditions under which a navigation image is acquired last time and create a natural navigation image. A navigation-image acquiring section controls a placement-table control section on the basis of designation of addition of a region to a navigation image and, when present imaging conditions are different from the last imaging conditions, changes the imaging conditions to the last imaging conditions, acquires a region to be added with an imaging element, and causes a display section to display an image of the acquired region to be added and an existing navigation image.

Abstract: A three-dimensional measurement device which is capable of increasing the operability at the time of repeatedly performing dimension measurement for a plurality of measurement target objects having substantially the same shape is provided. There are included a template storage unit for storing, as a template, model three-dimensional shape data and an operation procedure of dimension measurement performed on the model three-dimensional shape image, and a positional relationship specification unit for specifying a relative positional relationship between the model three-dimensional shape data and measurement three-dimensional shape data. The geometric element extraction unit specifies a geometric element of a measurement three-dimensional shape based on the relative positional relationship and the template, and the dimension value calculation unit performs dimension measurement on the measurement three-dimensional shape based on the relative positional relationship and the template.

Abstract: The invention provides a shape measuring device, a shape measuring method, and a shape measuring program capable of accurately and easily positioning a measuring object at a focus of a light receiving unit when measuring the shape of the measuring object. An image of a measuring object captured by a light receiving unit is displayed on a display section, and an arbitrary position on the image of the measuring object is specified by a user. A relative distance between the light receiving unit and a stage is changed so that the specified position coincides with a focus of the light receiving unit. The light emitted from a light projecting unit is reflected by the measuring object and received by the light receiving unit. Stereoscopic shape data of the measuring object is generated by a triangular distance measuring method based on a light receiving signal output by the light receiving unit.
