Position accuracy

Position error across each complete recording.
Summary figures show our method for the selected recording.

High-accuracy trajectory reconstruction for tabletop UMI. Across the recordings compared here, our method achieves lower SE(3) position error than MapAnything and Basalt, with output scale preserved.

Each method is evaluated at its valid output timestamps.

SE(3) aligns rotation and translation without changing scale. Scale to reference is a separate diagnostic: a factor closer to 1 indicates closer agreement in overall scale.

Rotation and jitter definitions

Rotation error is the median residual angle after one constant orientation alignment per recording. Jitter is the RMS deviation from a 0.2 s moving average, measured at a common 50 Hz for metric trajectories with native output of at least 40 Hz. It is not a measure of position accuracy. Missing intervals are not connected; unavailable values read “—”.

03 / DATA EXAMPLES

Examples

Video and trajectory replayed in sync across several recordings.
Each can be played on its own or opened in full.

NOTE

Method

Each complete recording is evaluated on its own against an externally measured reference. Only overall position and heading are aligned, so the reconstruction keeps its original scale. Error statistics cover the moments where reference data is valid.

Video and trajectory are synced by recording time.
