Abstract

The invention relates to a three-dimension model retrieval system, which comprises a client and an application server side connected with the client; wherein, the client is provided with a user interface which submits searched keywords to the system and uploads the three-dimension model as well as provides users with interactive retrieval and result show of the three-dimension model; the application server side comprises a database which stores various three-dimension models and characteristic data; similarity measurement module for computing the similarity of the three-dimension model; retrieval module for calling the similarity measurement module and retrieving the three-dimension model and displaying retrieval results according to the searched keywords input by user. The three-dimension model retrieval system can realize retrieval of the three-dimension model and warehousing motion of the three-dimension model with visual and convenient retrieval and display modes, which is helpful for user to timely and precisely retrieve and look over the three-dimension model, thereby being convenient in operation and strong in extensibility and providing great convenience for research work.

Description

technical field [0001] The invention relates to a retrieval system, in particular to a system for retrieving three-dimensional models. Background technique [0002] In recent years, with the increasing popularity of 3D modeling tools and scanning equipment, the rapid development of the Internet and graphics chips, 3D model databases will also penetrate into all aspects of people's lives in the near future, and the analysis and matching technology of 3D shapes will soon promote Developments in other related application areas. [0003] As for the retrieval of 3D models, the acquisition of object models becomes feasible and easier due to 3D model scanning equipment; numerous 3D modeling software and tools make the design of 3D models easier; and the reuse of 3D models also makes design ( CAD) thinking has changed, that is, from how to construct a 3D model to how to find and obtain a model, and how to construct a new model from an existing model; thus, the retrieval of a 3D mod...
