Efficient Visual Localization with Place Recognition Anywhere Model (PRAM)


title_rewrite


The 360Loc dataset introduces a practical implementation of 360° mapping combining lidar data with 360° images to generate ground truth 6DoF poses. It enables the evaluation of visual localization methods on 360° reference images and queries from pinhole, fisheye, and 360° cameras, addressing the challenge of cross-device visual positioning.
