Ghosts in the Point Clouds: De-glaring LiDAR in the Transient Domain
Researchers have developed a new method to combat internal glare artifacts in solid-state LiDAR sensors, a problem that creates phantom objects and obscures real ones. The proposed solution models this glare as a linear operator, the Transient Glare Spread Function (TGSF), acting on transient LiDAR measurements. Their training-free approach works on low-level LiDAR detections before point-cloud formation, effectively suppressing glare while preserving true scene structure, and is compatible with existing sensors.
