The 3D model retrieval technology has been widely used in many fields, then the 3D model retrieval based on content is proposed, feature extraction becomes the key to retrieve accurate or not, using wavelet transform combined with wave frequency method of feature extraction can partly solve the problem of ambiguity, the experiment proved that the algorithm improve the efficiency and accuracy of retrieval.
