Pre-requisites

For convenience, we provide a Dockerfile to build a container image to run the code. The image will contain the Python dependencies and a build of COLMAP.

Your system will need:

1. Docker (>= 19.03)

2. NVIDIA Docker

3. NVIDIA GPU driver 418 or later.

Build the container image:

docker build -t xtreme-view .

Download the models

You can download the models from the NVIDIA GPU CLOUD registry using:

./download_model.sh

Running the code

Place your sequence of images in a directory tree with root data, followed by a directory per sequence, e.g., data/0000, and place all images in the sequence into the data/0000/images sub-directory.

Launch the container using the provided script:

./launch_container.sh

Run COLMAP on a sequence of images to get the camera parameters:

./run_colmap.sh /data/0000

Run the extreme view code generation:

python run_xtreme_view.py /data/0000 --input_views=6,8

This will run the extreme view synthesis code using images 6 and 8 of the sequence /data/0000. You can modify the code to use different virtual cameras.

You can run COLMAP and the extreme view synthesis on all the sample sequences:

./run_colmap_all.sh
./run_xtreme_view_all.sh

The results are stored in the sequence directory under xtreme-view. For example, for data/0000 you will find the results in the directory data/0000/xtreme-view. The initial view synthesis is located under output and the the refined one under refinement.
