Are Large-Scale 3D Models Really Necessary for Accurate Visual Localization?

teaser.jpg

Accurate visual localization is a key technology for autonomous navigation. We demonstrate experimentally that large-scale 3D models are not strictly necessary for accurate visual localization. We create reference poses for a large and challenging urban dataset. Using these poses, we show that combining image-based methods with local reconstructions results in a pose accuracy similar to the state-of-the-art structure-based methods. Our results suggest that we might want to reconsider the current approach for accurate large-scale localization.

Dataset

  1. 6DoF reference poses for San Francisco dataset.

  2. Our referece poses are computed on top of the SF-0 model provided by Li, Snavely, et. al. For more details about their dataset, please refer http://landmark.cs.cornell.edu/

  3. Evaluation package 03/10/2017

The following older versions have a bug on plotting the new results. When the result file list is shorter than 442, the graph shows unnecessarily good result.
