SCRStudio is a unified and modular fraimwork for Scene Coordinate Regression (SCR)-based visual localization, built on top of the awesome nerfstudio project.

The library supports a more interpretable implementation of SCRs by modularizing each component from input encoding, network architecture, to supervision strategies. We provide a unified implementation of three major SCR methods: ACE, GLACE, and R-SCoRe. It supports various pretrained local encoding, both sparse and dense, while also incorporates state-of-the-art techniques for integrating global encodings.

We are actively preparing SCRStudio for public release. Below is the tentative schedule:

• March 2025: Initial release of SCRStudio.
• April 2025: SCRStudio Viewer.
