S3KF: Spherical State-Space Kalman Filtering for Panoramic 3D Multi-Object Tracking
The authors propose S3KF, a panoramic 3D multi-object tracking framework based on a motorized rotating LiDAR and a quad-fisheye camera rig. It models object bearing on the unit sphere S^2 using a two-degree-of-freedom tangent-plane parameterization and jointly estimates it with box scale and depth dynamics.
