AI Guide Dog让视障者手机实时导航，支持室内外自主探索与目标导向路径预测。
AI Guide Dog: Egocentric Path Prediction on Smartphone
- 仅用视觉信息做多标签分类，实时输出方向指令。
- 融合GPS与高层指令实现室外有目标导航，处理室内无目标多路径不确定性。
- 首个兼顾室内外、有目标与探索式导航的轻量级手机系统，适合残障辅助研究者。
本文提出AI Guide Dog（AIGD），一种专为视障用户设计的轻量级第一人称（自视角）导航系统，可在智能手机上实现实时部署。AIGD采用纯视觉的多标签分类方法，预测方向指令，确保在多样化环境中安全通行。我们提出一种基于目标的户外导航新方法，融合GPS信号与高层方向信息；同时针对无目标室内导航中的多路径不确定性，提出有效处理机制。AIGD是首个能同时支持有目标导向与探索性导航，并覆盖室内外场景的导航辅助系统，建立了盲人导航的新基准。论文提供了方法、数据集、评估结果及部署实践，以推动辅助导航系统的进一步创新。
原文摘要 · Abstract (English)
This paper presents AI Guide Dog (AIGD), a lightweight egocentric (first-person) navigation system for visually impaired users, designed for real-time deployment on smartphones. AIGD employs a vision-only multi-label classification approach to predict directional commands, ensuring safe navigation across diverse environments. We introduce a novel technique for goal-based outdoor navigation by integrating GPS signals and high-level directions, while also handling uncertain multi-path predictions for destination-free indoor navigation. As the first navigation assistance system to handle both goal-oriented and exploratory navigation across indoor and outdoor settings, AIGD establishes a new benchmark in blind navigation. We present methods, datasets, evaluations, and deployment insights to encourage further innovations in assistive navigation systems.
