<P>PROBLEM TO BE SOLVED: To provide a method and a device for measuring dimensions of a tool which can measure the dimensions of the tool even if the tool has a larger diameter than the field of vision of an imaging device. <P>SOLUTION: When a machine tool 10 cannot fit the overall outline of the tool 20 inside the field of vision V for an image from the imaging device 33, the field of vision V of the imaging device 33 is moved by relatively moving the imaging device 33 and the tool 20. In addition, the imaging device 33 can follow the outline 54 of the tool 20 by moving the field of vision V because the movement direction 53 for the field of vision V is determined based on the partial outline line 51 specified based on image data. In this way, even when measuring dimensions for the tool 20 with a larger diameter than the field of vision V of the imaging device 33, a partial outline 51 of a desired range, for example, is specified. An outline of a desired range for the tool 20 is extracted if a plurality of specified partial outlines 51 are combined. Measurements of the dimensions of the tool 20 is possible by using such outlines. <P>COPYRIGHT: (C)2012,JPO&INPIT |
