trt_pose

Want to detect hand poses? Check out the new trt_pose_hand project for real-time hand pose and gesture recognition!

trt_pose is aimed at enabling real-time pose estimation on NVIDIA Jetson. You may find it useful for other NVIDIA platforms as well. Currently the project includes

• Pre-trained models for human pose estimation capable of running in real time on Jetson Nano. This makes it easy to detect features like left_eye, left_elbow, right_ankle, etc.

• Training scripts to train on any keypoint task data in MSCOCO format. This means you can experiment with training trt_pose for keypoint detection tasks other than human pose.

To get started, follow the instructions below. If you run into any issues please let us know.

Getting Started

To get started with trt_pose, follow these steps.

Step 1 - Install Dependencies

1. Install PyTorch and Torchvision. To do this on NVIDIA Jetson, we recommend following this guide

2. Install torch2trt

   git clone https://github.com/NVIDIA-AI-IOT/torch2trt
   cd torch2trt
   sudo python3 setup.py install --plugins

3. Install other miscellaneous packages

   sudo pip3 install tqdm cython pycocotools
   sudo apt-get install python3-matplotlib

Step 2 - Install trt_pose

git clone https://github.com/NVIDIA-AI-IOT/trt_pose
cd trt_pose
sudo python3 setup.py install

Step 3 - Run the example notebook

We provide a couple of human pose estimation models pre-trained on the MSCOCO dataset. The throughput in FPS is shown for each platform

Model	Jetson Nano	Jetson Xavier	Weights
resnet18_baseline_att_224x224_A	22	251	download (81MB)
densenet121_baseline_att_256x256_B	12	101	download (84MB)

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

1. Download the model weights using the link in the above table.

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

3. Open and follow the live_demo.ipynb notebook

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