OpenPose has represented the first real-time multi-person system to jointly detect human body, hand, facial, and foot keypoints (in total 135 keypoints) on single images.

It is authored by Ginés Hidalgo, Zhe Cao, Tomas Simon, Shih-En Wei, Yaadhav Raaj, Hanbyul Joo, and Yaser Sheikh. It is maintained by Ginés Hidalgo and Yaadhav Raaj. OpenPose would not be possible without the CMU Panoptic Studio dataset. We would also like to thank all the people who have helped OpenPose in any way.

Runtime Analysis

We show an inference time comparison between the 3 available pose estimation libraries (same hardware and conditions): OpenPose, Alpha-Pose (fast Pytorch version), and Mask R-CNN. The OpenPose runtime is constant, while the runtime of Alpha-Pose and Mask R-CNN grow linearly with the number of people. More details here.

Features

Main Functionality:

Input: Image, video, webcam, Flir/Point Grey, IP camera, and support to add your own custom input source (e.g., depth camera).

Output: Basic image + keypoint display/saving (PNG, JPG, AVI, ...), keypoint saving (JSON, XML, YML, ...), keypoints as array class, and support to add your own custom output code (e.g., some fancy UI).

OS: Ubuntu (20, 18, 16, 14), Windows (10, 8), Mac OSX, Nvidia TX2.

Hardware compatibility: CUDA (Nvidia GPU), OpenCL (AMD GPU), and non-GPU (CPU-only) versions.

Usage Alternatives:

For further details, check the major released features and release notes docs.

Installation

If you want to use OpenPose without installing or writing any code, simply download and use the latest Windows portable version of OpenPose!

Otherwise, you could build OpenPose from source. See the installation doc for all the alternatives.

Quick Start Overview

Simply use the OpenPose Demo from your favorite command-line tool (e.g., Windows PowerShell or Ubuntu Terminal). E.g., this example runs OpenPose on your webcam and displays the body keypoints:

# Ubuntu
./build/examples/openpose/openpose.bin

:: Windows - Portable Demo
bin\OpenPoseDemo.exe --video examples\media\video.avi

You can also add any of the available flags in any order. E.g., the following example runs on a video (--video {PATH}), enables face (--face) and hands (--hand), and saves the output keypoints on JSON files on disk (--write_json {PATH}).

# Ubuntu
./build/examples/openpose/openpose.bin --video examples/media/video.avi --face --hand --write_json output_json_folder/

:: Windows - Portable Demo
bin\OpenPoseDemo.exe --video examples\media\video.avi --face --hand --write_json output_json_folder/

Optionally, you can also extend OpenPose's functionality from its Python and C++ APIs. After installing OpenPose, check its official doc for a quick overview of all the alternatives and tutorials.

Send Us Feedback!

Our library is open source for research purposes, and we want to improve it! So let us know (create a new GitHub issue or pull request, email us, etc.) if you...

  1. Find/fix any bug (in functionality or speed) or know how to speed up or improve any part of OpenPose.
  2. Want to add/show some cool functionality/demo/project made on top of OpenPose. We can add your project link to our Community-based Projects section or even integrate it with OpenPose!

Citation

Please cite these papers in your publications if OpenPose helps your research. All of OpenPose is based on OpenPose: Realtime Multi-Person 2D Pose Estimation using Part Affinity Fields, while the hand and face detectors also use Hand Keypoint Detection in Single Images using Multiview Bootstrapping (the face detector was trained using the same procedure as the hand detector).

Openpose
Что это такое?OpenPose - это библиотека для определения ключевых точек сразу у нескольких людей в реальном времени: она находит 135 ключевых точек тела, рук, лица и стоп на изображениях и видео - первая система, которая определяет все четыре типа точек одновременно и в реальном времени.
Это библиотека, под которую надо писать код, или готовая программа?И то и другое. Есть демо в командной строке для готовых функций, API на C++ и Python для своих пайплайнов, а также портативная сборка для Windows, которую можно запустить без единой строчки кода.
Как её запустить?Самый простой путь: скачать последнюю портативную версию для Windows и пользоваться OpenPose Demo из командной строки - без установки и без программирования. Либо собрать её из исходников по документации по установке.
На каких системах она работает?Ubuntu (20, 18, 16, 14), Windows (10, 8), Mac OSX и даже плата Nvidia TX2.
Можно ли использовать её в коммерческом проекте?Бесплатно - нет: OpenPose бесплатна только для некоммерческого использования. Отдельную коммерческую лицензию можно купить через FlintBox-страницу авторов.
Мне нужна видеокарта Nvidia, чтобы её запустить?Нет - есть версии под CUDA (видеокарты Nvidia), OpenCL (видеокарты AMD) и только на процессоре. Именно видеокарта даёт работу в реальном времени, но сборка только под CPU тоже работает.
А она может отслеживать одного и того же человека между кадрами видео?Да - в OpenPose есть трекинг одного человека, его используют для дополнительного ускорения или для визуального сглаживания скелета во времени.
Есть ли интеграция с Unity?Да - авторы дают OpenPose Unity Plugin, который идёт в списке рядом с сопутствующими проектами, например кодом для обучения и датасетом стоп.
Код для обучения включён, или это только запуск готовых моделей?Этот репозиторий - для запуска моделей. Код для обучения и датасет стоп OpenPose - отдельные сопутствующие проекты, а сами методы описаны в статьях CVPR 2017 и IEEE TPAMI, ссылки на которые авторы просят указывать.
What are similar projects?ABot-Recon, ml-sharp, instant-ngp, InsertAny3D, freemocap, Open3D, opencv, lingbot-map
Which topics is it in?motion-capture, opencv, pose-estimation, 3d-reconstruction, 3d, real-time, video, inference, cpp, computer-vision, cuda, c++
