<p>Calibration object (11, 11B) for providing a reference dimension for measuring a surface shape of a measurement object to be stereo-imaged. The calibration object has an origin reference point target (110) corresponding to the origin position of three-dimensional measurement and reference target (113, 113B) arranged in such a manner that at least six points are included in each stereo image imaged from a plurality of imaging directions. For the reference target, reference target positions based on the origin reference point target (110) are decided in advance.</p> |
