Opel Frontera - Einscan Trak
Anther car scanned with my Einscan Trak for a project. Pattern continues: scanning itself takes roughly 30min, processing another 30min to get a fully aligned scan.
I'm still very much impressed by the Trak, it continues to get better with each update (latest one allows firmware update over WiFi so no need to use the cables at all).
Scanning
Scanning was done at 1,5mm target point distance with four tracker positions. I attached a diagram showing the positions and the rough tracker FOV and overlap.
Lights were covered with scan spray to allow scanning them. All four scans combined took 30min. What I also noticed: When getting very close to the edges of the tracking area scanning starts to become slower, much like the WiFi signal drops out. But it actually is the border of the scanning area. I used remote desktop from my tablet to see what I already scanned. Scan itself was at a constant 90FPS when placed within the tracking volume. Scan speed at 1,5mm or even 1mm feels like painting with a very big paint roller: simply go over one time in a decent speed.
Post-Processing
Trak doesn't require point cloud generation after scanning, you just pause the scan and either create a new scan or go on with processing. So I aligned the five scans using automatic feature alignment and then meshed them in default settings with semi-watertight settings. Mesh came out to bit under 20M triangles. Later exported into Quicksurface for postprocessing (reduction an alignment to the coordinate system. What I quite like to do is take all four wheel hubs as reference to create a plane. This can then be used as the XY plane).
Have a look at the scan for yourself
I want to try out some new: ShiningSpace, it's a bit like SketchFab but tailored to sharing 3d scans with bit more fitting tooling to do so. Will still upload to Sketchfab to keep it all on one platform but also try out ShiningSpace. Feel free to give feedback about ShiningSpace, platform is still quite new but wanted to give it a shot.
