A Right Invariant Extended Kalman Filter for Object based SLAM.

TLDR
Li et al. as mentioned in this paper proposed a right invariant extended Kalman filter (RI-EKF) for object-level SLAM, which automatically maintains the correct unobservable subspace.
Abstract
With the recent advance of deep learning based object recognition and estimation, it is possible to consider object level SLAM where the pose of each object is estimated in the SLAM process. In this paper, based on a novel Lie group structure, a right invariant extended Kalman filter (RI-EKF) for object based SLAM is proposed. The observability analysis shows that the proposed algorithm automatically maintains the correct unobservable subspace, while standard EKF (Std-EKF) based SLAM algorithm does not. This results in a better consistency for the proposed algorithm comparing to Std-EKF. Finally, simulations and real world experiments validate not only the consistency and accuracy of the proposed algorithm, but also the practicability of the proposed RI-EKF for object based SLAM problem. The MATLAB code of the algorithm is made publicly available.

Dense visual SLAM for RGB-D cameras
