New visual localization pipeline achieves sub-centimeter accuracy

Researchers from the University of Applied Sciences Northwestern Switzerland have introduced a new visual localization pipeline that leverages high-resolution street-level imagery to achieve sub-centimeter accuracy. This method combines prior-guided candidate selection with on-the-fly Structure-from-Motion reconstruction and PnP-based pose estimation. They also released the FHNW Muttenz dataset, which includes precisely georeferenced imagery and ground-truth poses, demonstrating median translation accuracies of 1-5 cm and rotational accuracies of 0.05-0.1°.
