Stairs
The NavVis M6 cannot climb stairs during scans. Try to scan staircases thoroughly to get a dense Point cloud from both adjacent floors. Well-mapped staircases will be important during Dataset alignment since they connect different floors and are clearly visible in the point clouds.

Scan Staircases Thoroughly
Slowly rotate and move so that the vertical laser scanners scan the stairs and the individual steps.

Lifting the Mobile Mapping System
Finish the current dataset. Pull the camera head all the way down, then pull the mobile mapping system by the handles at its head. Do this only while the scan is not running.
