Apparatus for generating three-dimensional model data

An apparatus for generating three-dimensional model data of a structural member constituting a machine tool in which a slide is movable in directions of at least first and second axes that are perpendicular to each other, wherein

• said apparatus comprises:
• first, second, and third imaging means, each of said imaging means comprising two imaging sections which are spaced apart from each other by a predetermined distance, said structural member being imaged by said imaging sections to generate two-dimensional image data;
• and
• model data generating means for generating three-dimensional model data including at least shape data which define a three-dimensional shape of said structural member, on the basis of sets of two two-dimensional image data which are generated respectively by said first, second, and third imaging means,
• said first imaging means is configured so that said two imaging sections are arranged along said second axis or a third axis which is perpendicular to said first and second axes, and said imaging sections image said structural member in a direction of said first axis,
• said second imaging means is configured so that said two imaging sections are arranged along said first axis or said third axis, and said imaging sections image said structural member in a direction of said second axis, and
• said third imaging means is configured so that said two imaging sections are arranged along said first axis or said second axis, and said imaging sections image said structural member in a direction of said third axis.
