RS-VIO Rust Stereo Visual-Inertial Odometry https://github.com/charleshamesse/RS-VIO Features

  • Patch-based stereo feature tracking: Multi-scale optical flow tracking using 52-point patterns for robust feature correspondence between stereo pairs.
  • Sliding window bundle adjustment: Joint optimization of camera poses and 3D map points using apex-solver with configurable window size.
  • PnP motion tracking: Perspective-n-Point pose estimation for inter-frame tracking between keyframes.
  • Keyframe selection: Automatic keyframe selection based on translation and rotation thresholds.
  • Multi-camera model support: Supports pinhole-radtan and EUCM camera models with distortion handling, more camera models can be integrated easily.
  • Dataset support: Players for EuRoC, TUM-VI, and 4Seasons datasets with configurable parameters.
  • 3D visualization: Real-time visualization of trajectories, map points, and camera frustums using Rerun.
