Sensor overview

High-level sensor availability before the detailed sensor records below.

Ground truth

Reference scope, method, rate, coverage, and provenance.

Ground-truth references for EnvoDat
Scope Method Reference system Count Rate Coverage Reference provenance
External
Measured using equipment independent of the platform’s normal onboard sensor pipeline.
Derived
Computed primarily from the dataset’s own recorded sensors.
Hybrid
Combines independent reference equipment with onboard measurements.

Reference notes
Per-scene input LiDAR/inertial constraints; map overlays are not independent pose-error certification.

Known or intentional limitations

Reported constraints and characteristics to check before using the dataset.

Twenty-six sequences cover thirteen scenes. Point clouds, LiDAR-derived image layers, selected image frames and annotation polygons use different counting units; ten modalities do not mean ten physical sensors.

GLIM pseudo-trajectories and reconstructed maps reuse LiDAR/inertial inputs. Map overlays and cloud-scale comparisons do not certify independent pose accuracy or complete timestamp coverage.

The paper describes approximate ROS pairing with a few seconds of accuracy. Achieved alignment uncertainty remains unknown and is not converted into a millisecond synchronization guarantee.

Fine-grained polygon labels cover selected images. Calibration procedures do not by themselves establish complete downloadable raw sessions; scene download links use the author data-request form.
