AbstractExisting landmark retrieval methods cannot provide a
comprehensive solution, by which user can view different angles
of landmark. In this paper, we propose a novel approach to
reconstruct and retrieve 3D landmark models by direct 2D to 3D
matching. In an offline module, firstly, attention-based 3D
reconstruction method is proposed to reconstruct sparse 3D
landmark models. Secondly, we construct textured 3D landmark
model for each sparse 3D landmark model. Finally, a 3D
landmark recognizer is built for each landmark based on the 3D
landmark model. In online module, query images are recognized
by the 3D landmark recognizers using a 2D to 3D matching
approach. For each recognized query image, a 3D landmark
model and a 3D landmark texture model are presented as a query
result. Experimental results demonstrate the effectiveness of our
proposed approach.
