LiftNav: Path Planning via Semantic Lifting in TSDF-Guided Gaussian Splatting 事件

LiftNav: Path Planning via Semantic Lifting in TSDF-Guided Gaussian Splatting arXiv:2605.31376v1 Announce Type: cross Abstract: Autonomous robots in unknown indoor environments require both reliable collision avoidance and object-level understanding. Classical representations such as TSDF support safe planning but lack semantics, while photorealistic methods like Gaussian Splatting (GS) provide rich appearance yet suffer from soft geometry, limiting precise obstacle avoidance. We present LiftNa
