Abstract

The present invention provides a method of collating images and an apparatus for collating images capable of collating an image for collation taken in as digital data with an image for reference stored as digital data comparatively simply and surely. There are provided image information extracting means for extracting plural pieces of one-dimensional information from within an image for collation or within an image for reference, positional information group determining means for collating the one-dimensional information with an image for collation or an image for reference of the object, thereby to obtain positional information groups at locations where a coefficient of coincidence of data reaches a set value or higher with respect to respective one-dimensional information, and deciding means for deciding that the image for collation and the image for reference are identical when a combination of data having a relative positional relationship which coincides with the relative positional relationship of the extracted one-dimensional information or is within prescribed dispersion exists among positional information groups obtained with respect to respective one-dimensional information.
