Realtime Body Measurements using Bodypix

Greetings !!
I am currently working on a project where I want to predict the Size of the customer in Realtime, I am thinking of using Bodypix model to do the same. Can I get some help or suggestions on how to get body measurements like Chest size and Waist size using BodyPix model. What is the logic behind it?

hello you manage to solve the problem?
