Building a 3D model of a person based on a photo. How to do it quickly and conveniently?

Question

3D

Good afternoon,
Every day, once again the success of AI. But the good old problem has not been solved: the quick creation of a person's avatar in 3D. Briefly, the task is formulated as follows: to form a 3D image of the human body based on photographs with minimal involvement. And minimal manual processing. Or so that processing is only needed at first: for training and eliminating artifacts
During the brainstorming session, they came up with the following idea:
1. Give everyone stretchable T-shirts marked with squares of a fixed size
2. A person takes three photos: 2 profiles and full face
3. Based on the distortion of the squares a 3d model is calculated at our facilities
4. A 3d image is generated for use by
Profit!
Actually the question is: what do you think about the complexity and the necessary resources for such a scheme?
Are there any other suggestions. :) the main thing is to be simple
Current programs for this are hell, of course
I will be glad to discuss

Answer 1

Try to make a texture from photos
In my opinion, Roman's method is more successful.

Answer 2

I just found the instructions .

Answer 3

Algorithms for building 3D models are just based on the fact that the camera (the point from which the photo is taken) changes, but the object itself does not. So stretchy T-shirts just don't fit, they violate that assumption; usually, either a previously known size marker is used (for example, as in this manual https://docs.opencv.org/3.1.0/d5/dae/tutorial_aruc... or some key points are found algorithmically.
As far as I know, simple and there is no universal solution to this problem in this formulation.As a starting point, you can read about https://en.wikipedia.org/wiki/Photogrammetry.
