fit SMPL model using 3D joints

Prerequisites

We have tested the code on Ubuntu 18.04/20.04 with CUDA 10.2/11.3

Installation

First you have to make sure that you have all dependencies in place. The simplest way to do is to use the anaconda.

You can create an anaconda environment called fit3d using

conda env create -f environment.yaml
conda activate fit3d

Download SMPL models

Download SMPL Female and Male and SMPL Netural, and rename the files and extract them to <current directory>/smpl_models/smpl/, eventually, the <current directory>/smpl_models folder should have the following structure:

   smpl_models
    └-- smpl
        └-- SMPL_FEMALE.pkl
        └-- SMPL_MALE.pkl
        └-- SMPL_NEUTRAL.pkl

Demo

Demo for sequences

python fit_seq.py --files test_motion2.npy

The results will locate in ./demo/demo_results/
