Human Performance Capture from Monocular Video in the Wild

Paper | Video | Project Page

Official code release for 3DV 2021 paper Human Performance Capture from Monocular Video in the Wild. We propose a method capable of capturing the dynamic 3D human shape from a monocular video featuring challenging body poses, without any additional input.

Test on 3DPW dataset

Download 3DPW dataset

modify the dataset_path in test.conf.
run bash mesh_recon.sh to obtain the rigid body shape.
run bash registration.sh to register a SMPL+D model to the rigid human body.
run bash tracking.sh to capture the human performance temporally.

Test on your own video

run OpenPose to obtain the 2D keypoints.
run LGD to acquire the initial 3D poses.
run MODNet to extract sihouettes.

Acknowledgement

We use the code in PIFuHD for the rigid body construction and adapt IPNet for human model registration. We use off-the-shelf methods OpenPose and MODNet for the extraction of 2D keypoints and sihouettes. We sincerely thank these authors for their awesome work.
