Owing to the fast developments of the computer software / hardware
and the popularity of the internet, the applications using 3D models
are getting more flourishing. With the increase to the requirement for
more 3D models, the issue how to efficiently manage and retrieve these
3D models is manifesting its importance and should be further
researched. In this thesis, the discrete principal curvatures of the
vertices of the triangulated 3D models have been employed as the
extracted features of the models. The histograms were also applied to
carry out the retrieval of the 3D models. The robustness and invariance
of the proposed method to the geometric transformations like scaling,
rotating, and mirroring were also verified in this thesis. 3D model
experimental results show that the models with complicated surfaces
could be effectively retrieved from the database by our approach.
Furthermore, the performance of the proposed method is efficient in
terms of resources and time consumption. This approach and the foresaid
features have been implemented in this thesis.
