Introduction

Multi Person PoseEstimation By PyTorch

Results

Require

1. Pytorch
2. pytorch-lightning

Installation

1. git submodule init && git submodule update
2. cd pytorch-lightning; python setup.py install

Demo

• Download converted pytorch model.
• Compile the C++ postprocessing: cd lib/pafprocess; sh make.sh
• python demo/picture_demo.py to run the picture demo.
• python demo/web_demo.py to run the web demo.

Evalute

• python evaluate/evaluation.py to evaluate the model on coco val2017 dataset.
• It should have mAP 0.653 for the rtpose, previous rtpose have mAP 0.577 because we do left and right flip for heatmap and PAF for the evaluation. c

Development environment

The code is developed using python 3.6 on Ubuntu 18.04. NVIDIA GPUs are needed. The code is developed and tested using 4 1080ti GPU cards. Other platforms or GPU cards are not fully tested.

Quick start

1. Preparation

1.1 Prepare the dataset

• cd training; bash getData.sh to obtain the COCO 2017 images in /data/root/coco/images/, keypoints annotations in /data/root/coco/annotations/, make them look like this:

${DATA_ROOT}
|-- coco
    |-- annotations
        |-- person_keypoints_train2017.json
        |-- person_keypoints_val2017.json
    |-- images
        |-- train2017
            |-- 000000000009.jpg
            |-- 000000000025.jpg
            |-- 000000000030.jpg
            |-- ... 
        |-- val2017
            |-- 000000000139.jpg
            |-- 000000000285.jpg
            |-- 000000000632.jpg
            |-- ... 
        

2. How to train the model

• Modify the data directory in train/train_VGG19.py and python train/train_VGG19.py
