A three-dimensional data processing system performs a collating operation precisely and can reduce the quantity of data necessary for presenting candidate data. A storage device stores the three dimensional data of each reference body in a set of the primary compressed data, which has been prepared by compressing three-dimensional data in an irreversible compression method, and the secondary compressed data for compensating difference between the three-dimensional data restored from the primary compressed data and the original three-dimensional data. A server device collates, when it receives the collation object data, the three-dimensional data decompressed from the primary compressed data and the secondary compressed data of each reference object with the collation object data, and transmits the primary compressed data of the several reference objects of higher similarities to the client device. This client device decompresses and displays the primary compressed data on a display device.
