Abstract (in Japanese) (See Japanese page) 
(in English) Recognition methods for 3D objects using local features of their 2D images have been proposed. A drawback of these methods is that a huge amount of memory is required to store a lot of local features in a database. In this report, we propose a memory reduction method by using subspaces that are spanned by local features extracted from the same part of the object in different poses. The proposed method is successful to reduce the memory down to about 1/18 of the memory for storing all local features, while it is capable of keeping the recognition rate of 98.9\%. Since the subspaces are with the information of poses of objects, the proposed method is capable of estimating the pose of the object in the query image.
