Three-dimensional model data generating method, and three dimensional model data generating apparatus

An apparatus for generating three-dimensional model data including an attached object attached to a machine tool and at least a part of the machine tool, comprising:

• first imaging means for imaging the attached object attached to the machine tool to generate two-dimensional image data;
• second imaging means, disposed apart from the first imaging means, for imaging the attached object attached to the machine tool to generate two-dimensional image data;
• first model-data storing means for storing data related to a three-dimensional model of the attached object attached to the machine tool, the model data including at least shape data that define a shape of the attached object;
• second model-data storing means for storing data related to a three-dimensional model about the at least part of the machine tool, the model data including at least shape data that define a shape about at least part of the machine tool;
• image processing means, based on the two-dimensional image data, each of which are generated by the first and second imaging means, for recognizing a shape feature of the attached object;
• object recognizing means, based on the model data stored in the first model-data storing means and the shape feature recognized by the image processing means, for recognizing model data of an attached object imparted with the shape feature;
• and
• model-data generating means for calculating, based on the model data recognized by the object recognizing means and the shape feature recognized by the image processing means, a position and an attitude, of the three-dimensional model of the attached object, on the three dimensional model of the machine tool, and thereafter, generating, based on the calculated position and attitude, the model data recognized by the object recognizing means, and the model data stored in the second model-data storing means, three-dimensional model data including the attached object and at least the part of the machine tool.
