Patent ID: 8295614

Claim:
A collation apparatus for collating target data of an image or three-dimensional data of an object with reference data, the collation apparatus characterized by comprising: storage means for storing a variation model capable of generating model data of an image or three-dimensional data of an object by adjusting values of a plurality of parameters; model fitting means for defining, among the plurality of parameters, a parameter representing a judgement target of which sameness between the target data and the reference data is to be judged as a target parameter and other parameters as an external parameter, and for generating target model data that are most similar to the target data and reference model data that are most similar to the reference data based on the variation model under a condition in which the target parameter is set to be the same for the target data and the reference data; and model goodness-of-fit evaluation means for computing a model goodness of fit of the target model data and the reference model data to the target data and the reference data.
