sincronized camera and projector, high speed scanning.
It would be nice to get into details, and see if they sell the software/projector for DIY.

I don’t quite understand why, in the other case, synchronization is needed to speed up the shooting stage, if it still takes a lot of time to process (in contrast, for example, from the demo video that Polyga showed us with their version of "real-time" scanning ). On my homemade scanner based on RV DIY, I spend about 3.5-4.5 seconds on shooting. and another 12-15 seconds. for processing the footage taken by the moment when the scan element is displayed on the screen.

As a comparison,

FlexScan3D takes about 2.5s per capture using 3mp Imaging Source cameras on Directshow drivers.

With my 3mp Basler cams, capture time drops to 1s...

With the Hand held scanner in stationary mode, a single capture only takes 0.1s!

Mesh processing for each scan takes about 2.5s on my old and slow PC :lol:

This looks promising but they are still a bit behind the competition.

I like your setup Alonso
You did great!

I think that a part of the speed in Flexscan is due to a lower resolution of the cameras (and its higher speed of course).
In a future I would go for a DIY Flexscan, if they sell their projector again.
