Title:
A SEARCH METHOD OF 3D MODEL AND DEVICE THEREOF
Document Type and Number:
WIPO Patent Application WO/2006/069496
Kind Code:
A1
Abstract:
The invention discloses a search method of 3D model and device thereof. As stated in the invention, it transforms the query model and the object model into the sets of 2D-slice polygons respectively; calculates the similarity between each 2D slice in the query model and its corresponding 2D slice in the object model; gets the total similarity between the query model and the object model by accumulating the similarities of all the couples of 2D slices; and determines the search result according to the said total similarity. In accordance with the invention, it could easily realize the search function of 3D model, and it is not sensitive to geometric noise, thus there's no need to look for the characteristic correspondence between models.
