Camera motion is one part of the model.
The latest experiment evaluates 90 reconstructed camera positions: 0.397 m after global rotation, translation and scale alignment; 8.649 m in absolute coordinates. The aligned score removes global errors using the reference. Ground truth was used only for scoring, never construction.
It does not establish sub-metre surface accuracy. A spatial comparison against a surveyed point cloud or measured control points is still required.
SIH specifies spatial accuracy ≤1 m. The supplied statement does not define the evaluator’s exact error metric.
