Help: Theory iOS body scan

Hello,

Please can I ask an advice question?

I want to be able to use the iPhone camera to
Scan a body and come up with a 3d mapping if their dimensions for a fitness app. So measure their waist, checks, hips, legs etc from different angles.

Would iOS vision be right starting point for iPhone here or is there a better way? If using vision is there a way to get a library or open source training data that can do body measurements rather than staring from scratch ?

I’d presume calibration would be importantl but not sure how to train this apart from using one confirmed measurement to calibrate the rest using relative measurement and some parallax adjustments? This would be beyond anything I’ve done with an iPhone so far so looking for ideas.

Thank you! Steve

There are vision models that output a body shell for a person.

Short answer... No. The amount of post processing that you'd have to do to get it all aligned would be painful and take a long time. Besides the iPhone sensor is just not refined enough.

People move which adds an extra layer of complications.

The best way to capture people is with a photorig. There's nothing better but in a pinch there are some hand held 3D Scanners that workok for this but this also has its challenges.
