Dynamic Object-Based Point Cloud Registration for Roadside LiDAR Calibration in Low-Overlap Outdoor Deployments

Accurate calibration of roadside light detection and ranging (LiDAR) sensors is essential for providing autonomous vehicles with beyond-line-of-sight perception capabilities in large-scale outdoor environments. However, in such scenarios, low intersensor overlaps and sparse point clouds result in unstable feature corre...

Inter-3D VQA: A Roadside Multimodal Benchmark for 3D Spatiotemporally Grounded Visual Question Answering

This work introduces Inter-3D VQA, a large-scale roadside multimodal benchmark for 3D spatiotemporally grounded VQA at intersections, and proposes Inter-Geo, an MLLM baseline that integrates object- and scene-level aligned LiDAR representations, and Inter-Metrics, a unified evaluation framework for textual consistency,...
