TensorRT OpenPifPaf Pose Estimation

TensorRT OpenPifPaf Pose Estimation is a Jetson-friendly application that runs inference using a TensorRT engine to extract human poses. The provided TensorRT engine is generated from an ONNX model exported from OpenPifPaf version 0.12a4 using ONNX-TensorRT repo.

You can read this article on our website to learn more about the TensorRT OpenPifPaf Pose Estimation application.

Getting Started

The following instructions will help you get started.

Prerequisites

Hardware

• NVIDIA Jetson TX2
• NVIDIA Jetson Nano

Software

• You should have Docker on your device.

Install

git clone https://github.com/galliot-us/pose-estimation.git
cd pose-estimation/

Usage

Run on Jetson

• You need to have JetPack 4.4 installed on your Jetson device to run this Pose Estimation application.
• This application gets an image or a video as input in 321x193 or 641x369 resolutions. The two ONNX models with these input sizes of OpenPifPaf version 0.12a4 (openpifpaf_resnet50_321_193.onnx and openpifpaf_resnet50_641_369.onnx) are provided in Galliot-Models.
• The ONNX model will be downloaded based on the specifications in the Config file and the TensorRT Engine will be generated from the ONNX model automatically through the application with performing the following steps.
• Note that you need to have installed nvidia-container-runtime and set docker daemon default runtime to nvidia in /etc/docker/daemon.json to have GPU access during docker build

  
  # 1) Download/Copy Sample input
  ./download_sample_video.sh

3) Build Docker image for Jetson (This step is optional, you can skip it if you want to pull the container from neuralet dockerhub)

docker build -f jetson-4-4-openpifpaf.Dockerfile -t "galliot/pose-estimation-openpifpaf:latest-jetson-4-4" .

4) Run Docker container:

docker run --runtime nvidia --privileged -it -v $PWD:/repo galliot/pose-estimation-openpifpaf:latest-jetson-4-4
