Abstract: The dimension measurement device of one aspect of the present invention includes: an obtainer configured to obtain, from a measurement device for performing three dimensional measurement of a desired object, a set of coordinates in three dimensions of the desired object; a surface extractor configured to determine a focused surface constituting the desired object based on the set of coordinates, and extract a position of a boundary of the focused surface; a region extractor configured to extract, in relation to a candidate region corresponding to an object being a specific object attached to the focused surface, a position of an edge surrounding the candidate region; and a dimension generator configured to generate dimensional data necessary for creating a dimensional drawing of the desired object from the position of the boundary and the position of the edge.

Abstract: A modeling device obtains three-dimensional coordinates from a measurement device for taking three-dimensional measurements of the three-dimensional structure having faces to produce model information of the three-dimensional structure, and includes a face extractor, a vertex extractor and a model producer. The face extractor produces a plane equation describing a face based on coordinates of each measurement point of the face. The vertex extractor extracts a point simultaneously satisfying plane equations describing adjoining faces as a vertex shared among the faces. The model producer produces model information representing the three-dimensional structure based on plane equations and vertexes. The face extractor determines a plane equation by recalculation based on measurement points existing in a range of a prescribed distance from a plane candidate.
