Eyes All Around: Design and Analysis of 360-Degree LiDAR Perception Using Equivariant Feature Learning in Unstructured Traffic

arXiv:2606. 07626v1 Announce Type: cross Abstract: Perception in dense, unstructured urban traffic remains a major challenge for autonomous driving because of the wide variety of road users, frequent occlusions, irregular motion patterns, and the lack of standardized road layouts.

Multi-Modal Traffic Sign Detection with Semantic Attributes for Autonomous Driving

The paper introduces a multi‑modal traffic sign detection framework that fuses camera and LiDAR data using an Intensity‑Aware Deformable Fusion module to align retro‑reflective LiDAR cues with visual features. It also presents a dual motion‑model tracker to handle non‑linear perspective changes and a semantic attribute classification pipeline that estimates occlusion, readability, sign embeddedness, and road relevance. Evaluated on a dataset covering more than 60 countries and 2,500 hours of driving, the system achieves an Object Miss Ratio of 0.49% across 221,068 sequences, indicating strong global generalization for autonomous driving.

Open-vocabulary 3D object detection with promptable segmentation

The paper introduces an open‑vocabulary 3D object detection pipeline that uses a promptable segmentation model (SAM3) to generate instance masks from six surround‑view cameras. These masks are converted into metric 3D boxes, achieving up to 0.413 mAP/0.555 NDS without any training when supervised box geometry is borrowed at inference. The approach also improves a supervised LiDAR‑only detector by 0.034 mAP through a camera‑witness rule, demonstrating that measurement precision, not 2D detection, limits performance.

Lightweight LiDAR-Based Cone Detection Framework Using Random Forest for Formula Student Driverless

The paper introduces a lightweight LiDAR-only perception pipeline for Formula Student Driverless vehicles that runs entirely on CPU. It combines ground removal, IMU-based motion compensation, DBSCAN clustering, and a Random Forest classifier, reducing the feature set from 12 to 7 while maintaining high accuracy. On a dataset of 2,371 labeled clusters, the system achieves an F1-score of 98.33% with an end-to-end runtime of 3.13 ms.
