Accuracy and notes
Position accuracy
0.02 m
Accuracy notes
The paper reports query-image positional measurement error below 20 mm.
Reference notes
Smartphone poses are transferred from the mapping platform through separately performed per-phone intrinsic and extrinsic calibration.

Calibration data

Calibration reproducibility details are not reported.

Notes

Each phone was intrinsically calibrated with a checkerboard and extrinsically calibrated using total-station-assisted EPnP, but the public documentation does not establish that calibration parameter files are released.

Known or intentional limitations

Reported constraints and characteristics to check before using the dataset.

Some shop interiors are absent from the 3D model because they were not entered during scanning.

Repetitive structures and differences in devices, viewpoints, routes, and capture times make localization challenging.

The current release page and paper disagree on panorama-depth resolution, documenting 8192x4096 and 1024x512 respectively.

Notes
One released panoramic RGB-D database product. Each of the 679 panoramas also yields 36 perspective RGB-D images with a 60-degree field of view. The current release page documents 8192x4096 panorama depth files, while the paper reports 1024x512 depth panoramas.
