Yes definitely like the global markers route. Way easier and faster to scan and im getting cleaner scans. Unfortunately i don’t have a computer capable of doing the meshing and editing. Gonna try and get a new laptop to do this. Thanks forcall of your help guys.
I haven’t used it in a long time, but you can use the Range wireless with the laptop.
Looks like you got the hang of it now, but I would have thought too many markers, and too symmetrical.
There were spots it still kept saying more markers needed. But im getting the hang of it. The worst part is getting all the stickers and adhesive back off of everything.
Hi! Nice project! I noticed, nobody mentioned your fusion distance at 0.3mm might be far too low. The car parts usually consist of smooth surface with not much of surface details on their own!
The closer/lower the point fusion distance, the greater the file , fusion times and muuuuuuch more RAM needed.
I saw some great results with scanning body parts usinh fusion settings in the range of 1.0-1.5.
e.g. here Revopoint Trackit Volumetric Accuracy and Repeatability tested (with real-world examples)
Notice: even the points are farther away by choosing higher fusion distance , each point keeps the accuracy! You sjould get get a very nice smooth surface by bumping up the point distance when fusing because you reduce the “noise” ,too.. When doing the CAD model afterwards it should give you an accurate, even cleaner looking surface. You can DM me ,if you want me to do that one of these part for demonstration purposes - for free.

Also, consider using single shot mode:
Regardless of your fusion settings, significantly fewer images need to be processed, which greatly reduces the load on your system.
So would single shot mode be better for doing areas like this fender edge and maybe the vent area in the sideskirt? Having a hard time with small areas like this. I did it with feature tracking because with marker tracking it kept saying more markers needed.
Hi Ivan , he is using phone for that , his 8 GB RAM laptop is not enough to perform the processing at higher values .
The phone will limit the settings.

Single shot saves frames and therefore computational ressources. Overscanning is less probable, too. Otherwise the rules for normal/“fluid” marker scanning apply here, too. As experienced many times, after scanner calibration marker tracking can improve. You could try it , to see if it improves tracking. You can also place some helpful jigs (maybe a pole or something) with markers on them next to the edges of the “main” object for better/easier transition/tracking when going from one side to the other.

sent you a DM regarding this. LMK
I am not having very good luck with getting good enough scans with thos scanner. If i were to upgrade to a laser scanner would i get a cleaner surface on the scans or would even a miraco? Ive done global marker maping, feature tracking with the markers and even marker tracking and can’t get clean scans like i see on all these videos.
Miraco Plus only … However it offers the same far distance as Range with the difference that you can get better global marker scanning results regardless of small and big details so that would be better .it uses photogrammetry for global markers .
Laser scanner in your case would be helpful only Trackit for amazing job without markers and you free to scan large elements all at once in various materials .
Trying to go around the edges to get the bottom of the bumper and the top in the center for the mounting flange is still keeps saying add more markers so i just keep adding them. Its kinda frustrating.
It asking for more markets because it can’t see them at the angle when you capture the edges . This job is calling for Trackit !
The best i can cet this bumper to scan. I did this scan right on the laptop. My boss bought me one for work big enough to handle this program.
Hi.
For the transition around the corners you can use some additional object with markers on it , like a pole or something, and place it next to that corner. I probably would scan it in parts, too and for precise merging I would put some removable protruding features for easier alignment, if needed.

So i scanned the bumper again in several pieces using the global marker file i made of the entire bumper. I fuesed each scan and tried cleaning rhem up and merged them together. Then i meshed the whole merge scan and the surface looks horrible. How can i get this stuff smooth?
Did you cleaned it all before meshing ? It looks like a lot of lose and duplicate points , even after merging you need to clean up your scan before meshing , I think we go through it already .
I went through all the processing steps the best i could
If i were to send you the raw files of this bumper could you take a look at cleaning them up and show me what you do to get clean results?
