Ask HN: How Fit3d Works?

So, I want to make my own version of fit3d , the 3d body scanning app. Partly because it too expensive for me and partly to match my desired use. I thought opensource software like meshroom could be used to get a 3d point cloud, but the best use case I could find for scanning yourself alone was: standing still on a turntable that gets rotated 360° (not practical). Did fit3d have to build everything from ground up, a custom built photogrammetry tool, by building upon, for example https://ethz.ch/content/dam/ethz/special-interest/baug/igp/photogrammetry-remote-sensing-dam/documents/pdf/math-of-photogrammetry.pdf ?

hello-

Yes, Fit3D built everything from the ground up. The company invested far more than $10M to develop the 3D body scanning unit, measurement processing engine, wellness algorithms, and user and facility platforms at scale.

You can likely get a point cloud of a human on your own using off the shelf tools, but the other bits of Fit3D are far more complicated.

The company developed SNAP, which is $0 down and $100 / month to help in these cases. Check it out.
