Photogrametry - Detailed 3D Scans from Photographs

The Rayban scans look amazing. How long did it take and on what kind of processor?

Meshroom is indeed a great photogrammetry solution. Colmap is not bad either for free and fast software!
But the best solution for product scanning is RealityCapture and they have a free version as well.

Accuracy overall is about 0.15-0.2 mm but there are some deviations in underlit areas, as well as in unpredictable locations due to the feature extraction algorithms which one needs to tweak as much as possible for optimal results.

I have written an extensive article reviewing a range of solutions for one of my bigger clients here:
