Monoport: Monocular Volumetric Human Teleportation (SIGGRAPH 2020 Real-Time Live)

Time: Tuesday, 25 August 2020 (Pacific Time Zone)

report homepage report

Our volumetric capture system captures a completely clothed human body (including the back) using a single RGB webcam and in real time.


We run the demo with 2 GeForce RTX 2080Ti GPUs, the memory usage is as follows (~3.4GB at GPU1, ~9.7GB at GPU2):

Note: The last four dependencies are also developed by our team, and are all in active maintenance. If you meet any installation problems specifically regarding those tools, we recommend you to file the issue in the corresponding repo. (You don't need to install them manually here as they are included in the requirements.txt)

How to run our Siggraph RTL Demo

1. Setup the repo

First you need to download the model:

sh scripts/

Then install all the dependencies:

pip install -r requirements.txt

2. Start the main process as a server.

# if you want to use the input from a webcam:
python RTL/ --use_server --ip <YOUR_IP_ADDRESS> --port 5555 --camera -- netG.ckpt_path ./data/PIFu/net_G netC.ckpt_path ./data/PIFu/net_C

# or if you want to use the input from a image folder:
python RTL/ --use_server --ip <YOUR_IP_ADDRESS> --port 5555 --image_folder <IMAGE_FOLDER> -- netG.ckpt_path ./data/PIFu/net_G netC.ckpt_path ./data/PIFu/net_C

# or if you want to use the input from a video:
python RTL/ --use_server --ip <YOUR_IP_ADDRESS> --port 5555 --videos <VIDEO_PATH> -- netG.ckpt_path ./data/PIFu/net_G netC.ckpt_path ./data/PIFu/net_C

If everything goes well, you should be able to see those logs after waiting for a few seconds:

loading networkG from ./data/PIFu/net_G ...
loading networkC from ./data/PIFu/net_C ...
initialize data streamer ...

* Serving Flask app "main" (lazy loading)
* Environment: production
WARNING: This is a development server. Do not use it in a production deployment.
Use a production WSGI server instead.
* Debug mode: on
* Running on http://<YOUR_IP_ADDRESS>:5555/ (Press CTRL+C to quit)

2. Access the server to start.

Open the page http://<YOUR_IP_ADDRESS>:5555/ on a web browser from any device (Desktop/IPad/IPhone), You should be able to see the MonoPort VR Demo page on that device, and at the same time you should be able to see the a screen poping up on your desktop, showing the reconstructed normal and texture image.
