    摘要： This invention aims to create a three-dimensional model of satisfactory accuracy even when adopting a method of performing three-dimensional measurement by arbitrarily changing a positional relationship between an actual model and a camera, and aligning and integrating three-dimensional information restored by each measurement. A polygonal mark M having a shape in which a direction can be uniquely specified is attached to a predetermined area of an actual model WM of a work to be three-dimensionally recognized. A process of changing the orientation of the actual model WM such that a state in which the mark M is contained in the view of each camera is maintained, and then performing the three-dimensional measurement is executed over a plurality of times. A predetermined number of, or two or more pieces of three-dimensional information is selected from the three-dimensional information restored by each measurement, these pieces of three-dimensional information are aligned and integrated, the information corresponding to the mark is deleted or invalidated from the integrated three-dimensional information, and the three-dimensional information after such a process is set as a three-dimensional model.

    摘要： The device includes: an input unit (4) for receiving image data obtained by capturing images of an object by imaging units (C1 to C3); and an arithmetic unit (1) that performs: 1) finding a three-dimensional reconstruction point set that contain three-dimensional position information of segments obtained by dividing a boundary of the object in the image data, and a feature set that contain three-dimensional information regarding vertices of the segments, for each of multiple pairs of two different images; 2) calculating a total three-dimensional reconstruction point set and a total feature set by totaling the three-dimensional reconstruction point sets and the feature sets of the multiple pairs; and 3) matching a model feature set regarding model data of the object with the total feature set, thereby determining, among the total three-dimensional reconstruction point set, points corresponding to model points of the object.
