3. Conclusion

FEJ gives an significant improvement of precision on both mono and stereo version, while online calibration on intrinsic, extrinsic as well as dt(cam-imu synchronization error) give no obvious improvement, because EuROC provide good calibrations on these information.
Precision improved along with sliding window size inreased, while calculation increased too. There is no obviouse improvement on precision when sliding window size beyond 20. We found the best sliding window size on EUROC are 20(mono), 10(stereo).
Precision improved along with max slam points inreased, while calculation increased too.

Open VINS

Welcome to the Open VINS project! The Open VINS project houses some core computer vision code along with a state-of-the art filter-based visual-inertial estimator. The core filter is an Extended Kalman filter which fuses inertial information with sparse visual feature tracks. These visual feature tracks are fused leveraging the Multi-State Constraint Kalman Filter (MSCKF) sliding window formulation which allows for 3D features to update the state estimate without directly estimating the feature states in the filter. Inspired by graph-based optimization systems, the included filter has modularity allowing for convenient covariance management with a proper type-based state system. Please take a look at the feature list below for full details on what the system supports.
