## What it is
stella_vslam is a community-maintained fork of OpenVSLAM implementing a monocular, stereo, and RGBD visual SLAM system in C++. It supports multiple camera models (perspective, fisheye, equirectangular), can store and reload maps for relocalization, and offers a modular API with a separate ROS wrapper.

## Use cases
- estimate camera pose from video with visual SLAM
- build a 3D map from monocular or stereo camera footage
- localize new images against a prebuilt SLAM map
- run SLAM with a 360-degree equirectangular camera
- add visual odometry to a robot with ROS
- track camera position for AR or drone navigation

## When to choose
- you need a modular visual SLAM library supporting many camera models
- you want to store, load, and relocalize against prebuilt maps
- you use fisheye or equirectangular cameras like RICOH THETA or insta360
- you want an actively maintained OpenVSLAM successor with a ROS wrapper

## When to avoid
- you need a permissively licensed codebase without reservation - check the license history first
- you require dense reconstruction or depth maps rather than sparse feature-based SLAM
- you need a turnkey application rather than a C++ library to integrate
- you depend on the original OpenVSLAM repository, which is no longer available
