Abstract:
1. A three-dimensional data processing system comprising: a storage device that stores three-dimensional data of each reference object in a set of primary compressed data prepared by compressing the three-dimensional data in an irreversible compression method and secondary compressed data for compensating for the difference resulting from said irreversible compression method; a collating unit that collates three-dimensional data decompressed from the primary compressed data and the secondary compressed data of each reference object with collation object data, which are three-dimensional data or image data of a collation object; and a candidate display unit that decompresses the primary compressed data of several reference objects of higher similarities included in collation results and displaying the decompressed data on a display device, wherein a compression method in which a coupling coefficients for synthesizing certain three-dimensional data by linear-combining a plurality of basic three-dimensional data become the compressed data of the certain three-dimensional data is used as said irreversible compression method.
