Abstract:
1. A method for confirming three-dimensional model data, which confirms whether data which are previously created and are related to a three-dimensional model including an attached object attached to a machine tool and at least a part of the machine tool, the three-dimensional model data including at least shape data which define shapes of the machine tool and the attached object, are accurate, the method comprising: an actual-image-data generating process in which an actual attached object attached to the machine tool is imaged by an imaging camera from previously set one or more view point to generate two-dimensional image data; a virtual-image-data generating process for generating, by a computer process, two-dimensional image data of the attached object based on the three-dimensional model data which are previously created and include the attached object and the at least a part of the machine tool, the process in which a three-dimensional space is virtually set, the three-dimensional model including the attached object and the at least a part of the machine tool is disposed within the space, and a camera of the same condition as that of the imaging camera is virtually set and disposed, thereby generating the two-dimensional image data estimated to be obtained when the attached object related to the three-dimensional model, as well as the actual attached object, is imaged by the camera virtually set and disposed from the same view point as the previously set view point; and an image-data comparing process for comparing, by a computer process, the two-dimensional image data related to the actual attached object generated in the actual-image-data generating process and the two-dimensional image data of the attached object related to the three-dimensional model generated in the virtual-image-data generating process to determine whether these two-dimensional image data match, wherein the image-data comparing means compares a gray level value of each pixel in the two-dimensional image data generated by the imaging camera and a gray level value of each pixel in the two-dimensional image data generated by the virtual-image-data generating means to determine whether these gray level values match.
