AVC-Init: aggregated visual constraints for decoupled initialization in visual-inertial navigation

Accurate and stable initialization is critical for Visual-Inertial Odometry (VIO). Existing methods often formulate visual constraints at the individual-observation level, so their computational cost grows with the number of feature measurements. They may also maintain 3D landmarks in initialization, which increases th...

Passive LWIR Hyperspectral Ranging via Transmittance Extraction and Distance Alignment

Passive long-wave infrared (LWIR) hyperspectral ranging enables distance estimation in low-light and nighttime scenes by exploiting atmospheric absorption features in thermal radiance received through the atmosphere.Joint estimation of temperature, emissivity, and distance is computationally expensive. Reference-range...
