BMW Motorcycle - Einscan Rigil Markerless Laser vs IR mode
This is the promised re-scan of the motorcycle in markerless laser mode after the latest update enabled markerless laser scanning in standalone mode.
Scanning
The motorcycle was scanned in markerless alser mode on the Rigil using 1mm resolution and feature tracking without connection to a PC. For scanning itself I didn't do any preparations like scan spray and focused on the both sides with one scan per side whilst ensuring enough overlap for easy alignment in later steps.
While scanning the Rigil held roughly 20 FPS. Scanning itself took roughly 5 to 10min per side, so a a bit longer than in IR mode (was using 1.5mm there though).
Tracking performance with the Rigil was very good, much better than on my Rockit. In comparison to the IR mode it still is a bit worse, simply because IR mode has a scan range of over 1m and therefore can work with way more data for tracking. Stability and performance of markerless laser scanning generally was very good and it feels like a production ready feature not a beta version or first release (in IT speak).
Post-Processing
Post processing was done on my workstation and included generation of the point clouds, automatic feature alignment and subsequent meshing in recommended settings. Quicksurface was used for alignment to the coordinate system and reduction of the point cloud size. Since it came out quite large I reduced it to 4M so the scan could be uploaded to Sketchfab.
Results
Both laser and IR came out very good but in laser mode the improved detail and sharpness is directly noticeable. Also the surface quality is a good bit better in laser mode. Best open both scans side by side on Sketchfab and have a closer look at them.
Sketchfab
Sketchfab is like printables for 3d scans with a nice integrated viewer in browser and you can also download the scan, just look at the scan yourself.
Reddit sadly blocks the short links to Sketchfab, you have to search for the title instead:
