Feature matching method is the key technology of image retrieval. A matching method based on SVD is proposed in this paper. Firstly, the feature matrix is constructed and the eigenvalue matrix is calculated based on SVD transformation．Then, the eigenvalue matrix is mapped into vector space，and similarity is measured by comparing the angle between vectors. Finally, the matching method is applied to image retrieval. Experimental results show that the proposed method is feasible and superior to the traditional distance matching method.
