HP2-SLAM: Adaptive Hybrid ICP for Robust and Efficient LiDAR SLAM

HP2-SLAM以邻域大小自适应混合ICP提升LiDAR SLAM鲁棒性与效率，并在公开数据集上验证。

核心要点

• LiDAR SLAM难以同时兼顾鲁棒性、精度与效率，传统ICP在平面或重复场景中易退化。
• 方法采用平面性感知的自适应阈值，按局部几何结构与密度动态分类对应关系。
• 框架结合子地图管理、回环检测与位姿图优化，无需特征工程、学习模块或数据集调参。
• 在公开数据集上持续优于强几何基线，并在通用硬件上保持实时性能。

验证范围与局限：验证范围为公开可用数据集上的LiDAR SLAM，摘要未说明具体数据集或平台。

英文摘要 (Abstract)

Achieving robustness, accuracy, and efficiency simultaneously remains a central challenge in light detection and ranging (LiDAR) simultaneous localization and mapping (SLAM). While learning-based approaches deliver strong benchmark performance, they often require extensive training, substantial computational resources, and struggle to generalize to unseen or degenerate environments. Geometry-based methods are efficient and interpretable, yet their performance degrades in planar or repetitive scenes due to limitations of standard iterative closest point (ICP) formulations. We present HP2-SLAM, a minimalist yet robust LiDAR SLAM framework built around a neighborhood-size adaptive hybrid ICP. Our key insight is a planarity-aware adaptive threshold that dynamically classifies correspondences based on local geometric structure and density, thereby enabling a principled balance between point-to-plane and point-to-point residuals. This formulation stabilizes alignment in both structured and degenerate environments without feature engineering, learning modules, or dataset-specific tuning. Integrated into a complete SLAM pipeline with submap management, loop closure detection, and pose graph optimization, HP2-SLAM consistently outperforms strong geometry-based baselines across publicly available datasets while maintaining real-time performance on commodity hardware. Our results demonstrate that carefully designed geometric adaptation can achieve strong generalization and robustness without sacrificing simplicity or efficiency.
