Scanning thin/fin like composite objects

Dear community,

First of all let me thank you for reading and thinking about my post.
I’m new to 3D Scanning, but ran through a lot of PUTV and others articles and reviews.
I’m the owner of Revopoint POP2 Premium package, purchased on last Kickstarter.
I recalibrated my scanner with the beta software and was able to get 0.06 results, and confirmed those after that with accuracy test (avg of 0.75).

I’m trying to scan the following fin structure

It’s semi-opaque and filled with composites structure.
I have sprayed it with special NDT spray, so the scanner can detect it.
With all my tries, i tried scanning with the turn-table.

1st run:
The fin was placed down on the table. with its major surfaces pointing upwards/downwards and the scanner on tripod looking from above/angle.
I had some tracking issues, and smirred scans. I wasn’t able to catch the whole structure in one try of 300-400 frames per rotation, using the feature scan method.
When finally getting some mild results, i then figured out i was unable to align the upper and lower surfaces in the Revo Studio software, nor with features and aligning points. There was simply not enough common points to stitch these shells.

2nd run:
I have placed the fin standing on its based, using blue-tac, attached to the turn table.
The scanner was unable to detect the surfaces when the leading/trailing edges were passing in-front of it. And i was unable to do it hand-held. It lost track of the object everytime, both on feature and marking methods.

I would gladly hear your kind and experienced comments and suggestions.
Best regards,

Hi @Cpt.HeadCrab

please add more elements while scanning it , the edge is to fine to be scanned so you going to lose tracking , add some cube or anything to both sides of the objects on both sides so it keep tracking when it turns on the side , that is the best way , you can remove easy later the extra elements in Revo Studio
