Abstract:
1. A matching device comprising: an element selection unit implemented at least by a hardware and which selects elements corresponding to each other between a first feature vector representing features of an object and including a plurality of elements determined based on first data, and a second feature vector representing features of the object and including a plurality of elements determined based on second data; a similarity degree calculation unit implemented at least by a hardware and which calculates a score of a degree of similarly between the first data and the second data from the elements selected from the first feature vector and the second feature vector; a score correction unit implemented at least by a hardware and which corrects the score calculated by the similarity degree calculation unit so that the increment of the score increases with the increase in the amount of data used for the calculation of the degree of similarly; a three-dimensional data generating unit implemented at least by a hardware and which measures a three-dimensional shape of the object and generates three-dimensional shape data representing the three-dimensional shape of the object; and a two-dimensional image generating unit implemented at least by a hardware and which generates a two-dimensional image of the object represented by the three-dimensional shape data as a first image when a second image is given, so that posture of the object and illumination condition in the first image become similar to those in the second image, wherein the element selection unit makes the selection of the elements corresponding to each other between the first feature vector determined based on the first image and the second feature vector determined based on the second image.
