An apparatus for image measurement comprises a data setting portion for taking up one of a pair of stereoscopic images as a reference image and the other as a searched image and establishing a reference data block in the reference image and a searched data block in the searched image, a correspondence determining portion for determining correspondence between the reference data block and the searched data block, a data magnification changing portion for changing the magnification of image of the data in the reference data block according to the magnification of image of searched data in the searched image, and an image measuring portion for performing image measurement according to the output of the correspondence determining portion. The correspondence determining portion determines the correspondence by using the reference data block, of which the magnification of data has been changed in the magnification changing portion, and the searched data block.
