| dc.description.abstract-translated | At present, 3D retrieval systems that are content-based become very popular. In these systems similar models from a database are retrieved in accordance with a form of a template model. In an early era text-based retrieval systems were designed. These systems assign keywords to each model and then they retrieve similar models by comparing a sim ilarity of the keywords to a template. There are two problems in this approach. Keywords of each model have to be assigned manually and the second more difficult problem is that each person has a little different perception. Two people can assign two different sets of keywords to the same model. Contentbased retrieval system is a solution of these problems. This report deals with pr oblems, which are related to a design of a 3D content-based retrieval system, and with their solutions. The report consists of three main parts. The first part is interested in an issue of a feature extraction. An aim of the feature extraction is to describe a 3D model by a vector of real values characterizing a form of the model. This (multidimensional)vector may be an adequate representation of each model and therefore it can be used as an entry of a database system. The following two parts are dedicated to a design of that database system. The first part deals with types of queries, which the system may execute, and the second part deals with data structures and issues of multidimensional indexing and updating a 3D model database. | en |
