ABSTRACT:
In order to provide a data processing technique for easily and suitably executing an integrating process for a plurality of image groups obtained successively from different directions against the object to be the base for generating a three-dimensional shape data of an object, while the object SB in a first posture placed on a rotary stage is being rotated, images of the object SB are successively photographed by a photographing device so that a first image group is obtained. The posture of the object SB is changed into a second posture, so that a second image group of the object SB is obtained similarly. Corresponding points Sp1,Sp2,Sp3and the like of the object SB are specified on a partial first image extracted from the first image group and a partial second image extracted from the second image group. Conversion parameters of the first and second image groups are calculated from the information about the specified plural corresponding points, so that the integrating process is executed. As a result, the integrating process for the plural image groups can be executed easily and suitably.
