The program is tested with Python 3.8+ and torch 1.13.1 and dependencies in requirements.txt.

You will also need to install the following from sources:

• nerfstudio
• lightglue
• Hloc
• Feat2map

• Microsoft 7scenes
• 12scenes

The code is still under refactoring so it still contains hardcode and bugs.

• Hloc need to run first in order to obtain the sfm model (in this case we use triangulation from superpoint+superglue).
• Extract a subset of the dataset to train nerf on by preprocessing.py.
• Generate novel poses using create_novel_pose.py
• Generate synthetic images by using view_synthesis.py
• Generate descriptors by matching using generate_synthetic.py
• Finally training both synthetic and original data using Feat2map
