Not All Points Are Equal: Uncertainty-Aware 4D LiDAR Scene Synthesis

The paper frames the work as lidarPerception & SensingLidarA sensor that measures distance using laser light, often used in mapping and navigation. slamNavigation & LocomotionSLAMSimultaneous Localization and Mapping.. Start here because it defines what success means and which assumptions the rest of the method inherits.

This paper generates realistic 4D LiDARPerception & SensingLidarA sensor that measures distance using laser light, often used in mapping and navigation. scenes by focusing computational effort on hard-to-perceive areas (occluded regions, distant surfaces) using uncertainty guidance.
