PanopticStudio Toolbox

This repository has a toolbox to download, process, and visualize the Panoptic Studio (Panoptic) data.

Note:

  • Sep-21-2020: Currently our server is offline due to the power outage in the CMU Campus, and COVID-19 makes it difficult to access the server room. We will fix the issue as soon as possible. 
  • Sep-30-2020: Unfortunately, we found that our server has been broken and we are replacing it now. Please wait a couple of more weeks.
  • Oct-5-2020: Our server is back and online now!

Quick start guide

Follow these steps to set up a simple example:

1. Check out the codebase

git clone https://github.com/CMU-Perceptual-Computing-Lab/panoptic-toolbox
cd panoptic-toolbox

2. Download a sample data and other data

To download a dataset, named "171204_pose1_sample" in this example, run the following script.

./scripts/getData.sh 171204_pose1_sample

This bash script requires curl or wget.

This script will create a folder "./171204_pose1_sample" and download the following files.

  • 171204_pose1_sample/hdVideos/hd_00_XX.mp4 #synchronized HD video files (31 views)
  • 171204_pose1_sample/vgaVideos/KINECTNODE%d/vga_XX_XX.mp4 #synchrponized VGA video files (480 views)
  • 171204_pose1_sample/calibration_171204_pose1_sample.json #calibration files
  • 171204_pose1_sample/hdPose3d_stage1_coco19.tar #3D Body Keypoint Data (coco19 keypoint definition)
  • 171204_pose1_sample/hdFace3d.tar #3D Face Keypoint Data
  • 171204_pose1_sample/hdHand3d.tar #3D Hand Keypoint Data

Note that this sample example currently does not have VGA videos.

You can also download any other seqeunce through this script. Just use the the name of the target sequence: instead of the "171204_pose1panopticHD". r example,

./scripts/getData.sh 171204_pose1

for the full version of 171204_pose1 sequence:. You can also specify the number of videospanopticHDnt to donwload.

./scripts/getData.sh (sequenceName) (VGA_Video_Number) (HD_Video_Number)

For example, the following command will download 240 vga videos and 10 videos.

./scripts/getData.sh 171204_pose1_sample 240 10

Note that we have sorted the VGA camera order so that you download uniformly distributed view.

3. Downloading All Available Sequences

You can find the list of currently available sequences in the following link:

List of released sequences (ver1.2)

Downloading all of them (including videos) may take a long time, but downloading 3D keypoint files (body+face+hand upon their availability) should be "relatively" quick.

You can use the following script to download currently available sequences (ver 1.2):

./scripts/getDB_panopticHD_ver1_2.sh

The default setting is not downloading any videos. Feel free to change the "vgaVideoNum" and "hdVideoNum" in the script to other numbers if you also want to download videos.

You can see the example videos and other information of each sequence: in our website: Browsing dataset.

Check the 3D viewer in each sequence: page where you can visualize 3D skeletons in your web browser. For example: http://domedb.perception.cs.cmu.edu/panopticHDpose1.html

4. Extract the images & 3D keypoint data

This step requires ffmpeg.

./scripts/extractAll.sh 171204_pose1_sample

This will extract images, for example 171204_pose1_sample/hdImgs/00_00/00_00_00000000.jpg, and the corresponding 3D skeleton data, for example 171204_pose1_sample/hdPose3d_stage1_coco19/body3DScene_00000000.json.

extractAll.sh is a simple script that combines the following set of commands (you shouldn't need to run these again):

cd 171204_pose1_sample
../scripts/vgaImgsExtractor.sh # PNG files from VGA video (25 fps)
../scripts/hdImgsExtractor.sh # PNG files from HD video (29.97 fps)
tar -xf vgaPose3d_stage1.tar # Extract skeletons at VGA framerate
tar -xf hdPose3d_stage1.tar # Extract skeletons for HD
cd ..

5. Run demo programs

Python

This codes require numpy, matplotlib.

Visualizing 3D keypoints (body, face, hand):

cd python
jupyter notebook demo_3Dkeypoints_3dview.ipynb

The result should look like this.

Reprojecting 3D keypoints (body, face, hand) on a selected HD view:

cd python
jupyter notebook demo_3Dkeypoints_reprojection_hd.ipynb

The result should look like this.

This codes require numpy, matplotlib.

Visualizing 3D keypoints (body, face, hand):

cd python
jupyter notebook demo_3Dkeypoints_3dview.ipynb

The result should look like this.

Reprojecting 3D keypoints (body, face, hand) on a selected HD view:

cd python
jupyter notebook demo_3Dkeypoints_reprojection_hd.ipynb

The result should look like this.

Python + OpengGL

  • This codes require pyopengl.

  • Visualizing 3D keypoints (body, face, hand):

python glViewer.py

Matlab

Note: Matlab code is outdated, and does not handle 3D keypoint outputs (coco19 body, face, hand). Please see this code only for reference. We will update this later.

Matlab example (outdated):

>>> cd matlab
>>> demo

Skeleton Output Format

We reconstruct 3D skeleton of people using the method of Joo et al. 2018.

The output of each frame is written in a json file. For example,

{ "version": 0.7, 
"univTime" :53541.542,
"fpsType" :"hd_29_97",
"bodies" :
[
{ "id": 0,
"joints19": [-19.4528, -146.612, 1.46159, 0.724274, -40.4564, -163.091, -0.521563, 0.575897, -14.9749, -91.0176, 4.24329, 0.361725, -19.2473, -146.679, -16.1136, 0.643555, -14.7958, -118.804, -20.6738, 0.619599, -22.611, -93.8793, -17.7834, 0.557953, -12.3267, -91.5465, -6.55368, 0.353241, -12.6556, -47.0963, -4.83599, 0.455566, -10.8069, -8.31645, -4.20936, 0.501312, -20.2358, -147.348, 19.1843, 0.628022, -13.1145, -120.269, 28.0371, 0.63559, -20.1037, -94.3607, 30.0809, 0.625916, -17.623, -90.4888, 15.0403, 0.327759, -17.3973, -46.9311, 15.9659, 0.419586, -13.1719, -7.60601, 13.4749, 0.519653, -38.7164, -166.851, -3.25917, 0.46228, -28.7043, -167.333, -7.15903, 0.523224, -39.0433, -166.677, 2.55916, 0.395965, -30.0718, -167.264, 8.18371, 0.510041]
}
] }

Here, each subject has the following values.

id: a unique subject index within a sequence:. Skeletons with the same id across time represent temporally associated moving skeletons (an individual). However, the same person may have multiple ids joints19: 19 3D joint locations, formatted as [x1,y1,z1,c1,x2,y2,z2,c2,...] where each c ispanopticHDjoint confidence score.

The 3D skeletons have the following keypoint order:

0: Neck
1: Nose
2: BodyCenter (center of hips)
3: lShoulder
4: lElbow
5: lWrist,
6: lHip
7: lKnee
8: lAnkle
9: rShoulder
10: rElbow
11: rWrist
12: rHip
13: rKnee
14: rAnkle
15: lEye
16: lEar
17: rEye
18: rEar

Note that this is different from OpenPose output order, although our method is based on it.

Note that we used to use an old format (named mpi15 as described in our outdated document), but we do not this format anymore.
