3D model retrieval method based on area distributions

Large numbers of 3D model have been used in the product design and 3D artifact, but problems have occurred that attribute data was incomplete; the search method was inaccurate based on attributes. Consequently, the search engines could not provide effective search service. This paper proposes an area distributions based on method outlying with 3D system. According to this method, we first summarize the total area and average area of the vertex of the 3D model, then normalize the list of the area distributions list and Fourier transform the list; last, get the final area distributions list model, and map the search of the model to compare the area distributions list. Experiments have been conducted for comparing and evaluating the proposed algorithm utilizing the Engineering Shape Benchmark (ESB) database. The experiential results show that the proposed technique has effectively reflected the similarity among engineering models, and the match result of the extremely similar model is accurate and the retrieval performance has been significantly improved compared with traditional shape distribution method.
