映像場所認識のための新規視点合成の系統的評価
Systematic Evaluation of Novel View Synthesis for Video Place Recognition
5つの公開VPR画像データベースと7つの類似度手法を用いて、合成新規視点画像が場所認識性能に与える影響を系統的に評価した。少量の追加では認識精度が向上するが、大量追加では視点変化の大きさよりも追加枚数やデータセットの種類が重要であることを示した。

The generation of synthetic novel views has the potential to positively impact robot navigation in several ways. In image-based navigation, a novel overhead view generated from a scene taken by a ground robot could be used to guide an aerial robot to that location. In Video Place Recognition (VPR), novel views of ground locations from the air can be added that enable a UAV to identify places seen by the ground robot, and similarly, overhead views can be used to generate novel ground views. This paper presents a systematic evaluation of synthetic novel views in VPR using five public VPR image databases and seven typical image similarity methods. We show that for small synthetic additions, novel views improve VPR recognition statistics. We find that for larger additions, the magnitude of viewpoint change is less important than the number of views added and the type of imagery in the dataset.
