-  loosely coupled method, thus no information is returned to the estimator to improve the underlying OpenVINS odometry.
-  This codebase has been modified in a few key areas including: exposing more loop closure parameters, subscribing to
-  camera intrinsics, simplifying configuration such that only topics need to be supplied, and some tweaks to the loop
-  closure detection to improve frequency.
+* **[vicon2gt](https://github.com/rpng/vicon2gt)** - This utility was created to generate groundtruth trajectories using
+  a motion capture system (e.g. Vicon or OptiTrack) for use in evaluating visual-inertial estimation systems.
+  Specifically we calculate the inertial IMU state (full 15 dof) at camera frequency rate and generate a groundtruth
+  trajectory similar to those provided by the EurocMav datasets. Performs fusion of inertial and motion capture
+  information and estimates all unknown spacial-temporal calibrations between the two sensors.
