<P>PROBLEM TO BE SOLVED: To simply check accuracy of a calculated parameter when a parameter for three-dimensional measurement has been computed. <P>SOLUTION: In the calibration apparatus, after a parameter for three-dimensional measurement is computed by a calibration processing using a calibration workpiece in which two or more characteristic points with known positional relationship can be extracted from an image produced by imaging, three-dimensional coordinate computing processing is performed using the computed parameter for the two or more characteristic points in the stereoscopic image used to compute the parameter. Perspective transformation of each computed three-dimensional coordinate is performed to produce a projection image in which the transformed coordinate is expressed by a predetermined pattern, and which is displayed on a monitor device. <P>COPYRIGHT: (C)2011,JPO&INPIT |
