MirrorSentinel Elevator#

Elevator traversals recorded to study mirror and glass interference, as native .mcap episodes.

A rig carrying a ZED2 camera, an Ouster 3D LiDAR and the Ouster IMU was walked through elevator cabins. A LiDAR pointed at a mirror reports returns from behind it, so the cabin appears to extend into space that is solid wall. Eight traversals cover seven physical cabins, and each cabin was measured by hand so the real boundary can be compared against what the sensors report.

elevator_02 and elevator_03 are two runs of one cabin; the footprint field groups them.
