Local motion and stability
Local translation, rotation, static stability and height consistency.
Median difference between reconstructed and reference translation vectors
Median relative-rotation angle error
1 s static-window end-to-end drift · P90
Relative height deviation
Difference in height change from the start; positive means the reconstruction gained more height than the reference.
Output scale preserved; the zero line means height change matches.
Height change compared along the anti-gravity axis, with output scale preserved.
Motion error across time intervals
Measured from one whole-recording alignment, across several time intervals.

|---|
The ratio of reconstructed to reference translation length; close to 1 means matching motion scale.
Definitions
Translation error compares reconstructed and reference translation vectors over the same interval; rotation error compares their relative rotation. No extra scale is fitted.
The scale ratio counts only intervals where reference translation exceeds 10 cm. Static windows are identified from the reference trajectory; where none qualify, or the recording is too short, the value reads “n/a”.
Examples
Video and trajectory replayed in sync across several recordings.
Each can be played on its own or opened in full.

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. Supplementary metrics update once retesting finishes; pending items read “—”.
