AI总结:

本文系统综述54项2017年以来面向BVI人群的SLAM辅助导航研究,分类分析其技术、传感器、算力与机器学习方法,并评估实际效果、挑战及未来方向。

摘要:

近几十年来,人们开发了多种辅助技术,以提高盲人和视障(BVI)人士独立、安全导航的能力。与此同时,同步定位与地图构建(SLAM)技术已变得足够稳健和高效,可被用于开发这些辅助技术。我们首次对54项近期研究进行了系统文献综述,这些研究关注面向盲人和视障人士的基于SLAM的解决方案,重点考察2017年以来发表的文献。本综述探讨了该背景下采用的各种定位与地图构建技术。我们系统地识别并分类了不同的SLAM方法,分析了其定位与地图构建技术、传感器类型、计算资源以及机器学习方法。我们讨论了这些技术在盲人和视障导航中的优势与局限。此外,我们考察了各项研究中描述的主要挑战,包括影响可用性和采用率的实际挑战与考量。我们的分析还评估了这些基于SLAM的解决方案在真实场景中的有效性和用户满意度,从而洞察其对BVI人群移动能力的实际影响。本综述得出的见解识别了关键差距和未来研究机会,尤其是在应对动态和复杂环境所带来的挑战方面。我们阐述了SLAM技术如何具有提升视障人士有效导航能力的潜力。最后,我们提出了该领域未来的机遇与挑战。

英文摘要:

In recent decades, several assistive technologies have been developed to improve the ability of blind and visually impaired (BVI) individuals to navigate independently and safely. At the same time, simultaneous localization and mapping (SLAM) techniques have become sufficiently robust and efficient to be adopted in developing these assistive technologies. We present the first systematic literature review of 54 recent studies on SLAM-based solutions for blind and visually impaired people, focusing on literature published from 2017 onward. This review explores various localization and mapping techniques employed in this context. We systematically identified and categorized diverse SLAM approaches and analyzed their localization and mapping techniques, sensor types, computing resources, and machine-learning methods. We discuss the advantages and limitations of these techniques for blind and visually impaired navigation. Moreover, we examine the major challenges described across studies, including practical challenges and considerations that affect usability and adoption. Our analysis also evaluates the effectiveness of these SLAM-based solutions in real-world scenarios and user satisfaction, providing insights into their practical impact on BVI mobility. The insights derived from this review identify critical gaps and opportunities for future research activities, particularly in addressing the challenges presented by dynamic and complex environments. We explain how SLAM technology offers the potential to improve the ability of visually impaired individuals to navigate effectively. Finally, we present future opportunities and challenges in this domain.
