    - Download duc_se.pth from (Google Drive | Baidu pan), place to ./joints_detectors/Alphapose/models/sppe
    - Download yolov3-spp.weights from (Google Drive | Baidu pan), place to ./joints_detectors/Alphapose/models/yolo
  - HR-Net (Bad 3d joints performance in my testing environment)
    - Download pose_hrnet* from Google Drive | Baidu pan), place to ./joints_detectors/hrnet/models/pytorch/pose_coco/
    - Download yolov3.weights from here, place to ./joints_detectors/hrnet/lib/detector/yolo
  - OpenPose (Not tested, PR to README.md is highly appreciated )

  - Download pretrained_h36m_detectron_coco.bin from here, place it into ./checkpoint folder
- 2D Pose trackers (Optional)
  - PoseFlow (Recommended) No extra dependences
  - LightTrack (Bad 2d tracking performance in my testing environment)
    - See original README, and perform same get started step on ./pose_trackers/lighttrack

Usage

place your video into ./outputs folder. (I've prepared a test video).

Single person video

change the video_path in the ./videopose.py
Run it! You will find the rendered output video in the ./outputs folder.

Multiple person video (Not implemented yet)

For developing, check ./videopose_multi_person

video = 'kobe.mp4'

handle_video(f'outputs/{video}') 
# Run AlphaPose, save the result into ./outputs/alpha_pose_kobe

track(video)					 
# Taking the result from above as the input of PoseTrack, output poseflow-results.json # into the same directory of above. 
# The visualization result is save in ./outputs/alpha_pose_kobe/poseflow-vis

# TODO: Need more action:
#  1. "Improve the accuracy of tracking algorithm" or "Doing specific post processing 
#     after getting the track result".
#  2. Choosing person(remove the other 2d points for each frame)

Tips

The PyCharm is recommended since it is the IDE I'm using during development.
If you're using PyCharm, mark ./joints_detectors/Alphapose, ./joints_detectors/hrnet and ./pose_trackers as source root.
If your're trying to run in command line, add these paths mentioned above to the sys.path at the head of ./videopose.py

Advanced

As this script is based on the VedioPose3D provided by Facebook, and automated in the following way:

args = parse_args()

args.detector_2d = 'alpha_pose'
dir_name = os.path.dirname(video_path)
basename = os.path.basename(video_path)
video_name = basename[:basename.rfind('.')]
args.viz_video = video_path
args.viz_output = f'{dir_name}/{args.detector_2d}_{video_name}.gif'

args.evaluate = 'pretrained_h36m_detectron_coco.bin'

with Timer(video_path):
    main(args)

The meaning of arguments can be found here, you can customize it conveniently by changing the args in ./videopose.py.

Acknowledgement

The 2D pose to 3D pose and visualization part is from VideoPose3D.

Some of the "In the wild" script is adapted from the other fork.

The project structure and ./videopose.py running script is adapted from this repo

Coming soon

The other feature will be added to improve accuracy in the future:

Human completeness check.
Object Tracking to the first complete human covering largest area.
Change 2D pose estimation method such as AlphaPose.
Test HR-Net as 2d joints detector.
Test LightTrack as pose tracker.
Multi-person video(complex) support.
Data augmentation to solve "high-speed with low-rate" problem: SLOW-MO.
