Open-Vocabulary 3D Object Detection with Co-Distillation Discovery and Dual Guidance Robust Training

This work proposes a dual-guidance learning scheme, incorporating a scene-awareness-guided uncertainty regularization for the regression head and an LLM-guided hierarchical alignment for the classification head, effectively mitigating the negative effects of imprecise 3D bounding boxes and semantic ambiguity.

Explicit Geometry-Reflectance Domain Shift Modeling for Robust LiDAR Segmentation in Adverse Weather

The Geometry–Reflectance Collaboration Network (GRCNet) is introduced, which separately encodes geometry and reflectance and fuses them via robust multi-level feature collaboration to suppress weather-induced corruption while preserving complementary semantics.
