Abstract
A method for matching a first three-dimensional (3D) model includes obtaining 3D source information of a second 3D model, the 3D source information including a plurality of physical characteristics of the second 3D model, determining a plurality of factors of the second 3D model based on the obtained 3D source information, obtaining a first 3D fingerprint of the first 3D model from a memory, the first 3D fingerprint comprising a plurality of factors associated with the first 3D model, comparing the plurality of factors of the second 3D model to the plurality of factors of the first 3D fingerprint, providing information of a match confidence level between the first 3D model and the second 3D model based on the comparison, and storing a second 3D fingerprint of the second 3D model in the memory, the second 3D fingerprint including the determined plurality of factors of the second 3D model.
