Abstract
A method, apparatus and system for multimedia model retrieval are provided. The method includes: obtaining parameters of a multimedia model to be retrieved; performing a projection on the multimedia model according to the parameters of the multimedia model so as to obtain a projection image; performing a feature extraction on the projection image; matching a feature extraction result with stored model multimedia file information to obtain a retrieval result; training a support vector machine (SVM) with the multimedia model labeled by a user upon the retrieval result as a training sample set, performing a probability-based classification on the multimedia model by the SVM, and updating the retrieval result with a classification result. The system of the present invention illustrated by embodiments achieves favorable applicability and robustness, so that users may perform a rapid and precise retrieval on massive model data in these fields.
