TensorRT Pose Estimation

This project features multi-instance pose estimation accelerated by NVIDIA TensorRT. It is ideal for applications where low latency is necessary. It includes

• Training scripts to train on any keypoint task data in MSCOCO format

• A collection of models that may be easily optimized with TensorRT using torch2trt

This project can be used easily for the task of human pose estimation, or extended for something new.

If you run into any issues please let us know.

Tasks

Human pose estimation

This task involves detecting human body pose using models trained on the MSCOCO dataset.

Models

Below are models pre-trained on the MSCOCO dataset. The throughput in FPS is shown for each platform

Live demo

To run the live Jupyter Notebook demo on real-time camera input, follow these steps

1. Place the downloaded weights in the tasks/human_pose directory

2. Open and follow the live_demo.ipynb notebook

   You may need to modify the notebook, depending on which model you use

Setup

To install trt_pose, call this command

We assume you have already installed PyTorch, torchvision, and TensorRT

sudo pip3 install tqdm cython pycocotools
sudo apt-get install python3-matplotlib
git clone https://github.com/NVIDIA-AI-IOT/trt_pose
cd trt_pose
sudo python3 setup.py install
