RD-LIVO: Degeneracy-aware LiDAR–visual–inertial odometrywith adaptive observation covariance
Tightly-coupled LiDAR–visual–inertial odometry (LIVO) often drifts in degenerate environments because fixed observation noise models treat unreliable LiDAR and visual measurements as equally trustworthy during filtering. This paper presents RD-LIVO, a degeneracy-aware multi-sensor measurement framework that improves...
