■在本文中,我们全面回顾了盲人和视障人士户外旅行相关技术的现状和研究(BVIP),鉴于盲人导航辅助工具的类型多样,功能不完整。旨在为BVIP和盲人导航在户外出行领域的相关研究提供参考。
■我们编译了与盲人导航有关的文章,其中共有227人被列入搜索标准。从初集中选出一百七十九篇,从技术角度来看,阐述盲人导航的五个方面:系统设备,数据源,制导算法,相关方法的优化,导航地图。
■盲人辅助设备的可穿戴形式研究最多,其次是手持式辅助设备。基于视觉传感器的RGB数据类是最常见的导航环境信息数据来源。基于图片数据的目标检测在导航算法和相关方法中也尤为丰富,说明计算机视觉技术已成为盲人导航领域的重要研究内容。然而,导航地图的研究相对较少。
■在BVIP辅助设备的研究和开发中,将强调优先考虑属性,如轻盈,便携性,和效率。鉴于即将到来的无人驾驶时代,研究重点将放在可以帮助盲人导航的视觉传感器和计算机视觉技术的开发上。对康复的影响视觉缺陷可以很容易地帮助盲人和视力受损的人(BVIP)发展心理障碍。很少,如果有的话,设备在各个方面都能满足BVIP的户外旅行需求。在盲人户外导航领域没有全面的总结和概述。选择合适的辅助设备可以帮助BVIP更好地了解其周围环境的信息,并进行更安全,更有效的户外旅行。
UNASSIGNED: In this article, we comprehensively review the current situation and research on technology related to outdoor travel for blind and visually impaired people (BVIP), given the diverse types and incomplete functionality of navigation aids for the blind. This aims to provide a reference for related research in the fields of outdoor travel for BVIP and blind navigation.
UNASSIGNED: We compiled articles related to blind navigation, of which a total of 227 of them are included in the search criteria. One hundred and seventy-nine articles are selected from the initial set, from a technical point of view, to elaborate on five aspects of blind navigation: system equipment, data sources, guidance algorithms, optimization of related methods, and navigation maps.
UNASSIGNED: The wearable form of assistive devices for the blind has the most research, followed by the handheld type of aids. The RGB data class based on vision sensor is the most common source of navigation environment information data. Object detection based on picture data is also particularly rich among navigation algorithms and associated methods, indicating that computer vision technology has become an important study content in the field of blind navigation. However, research on navigation maps is relatively less.
UNASSIGNED: In the study and development of assistive equipment for BVIP, there will be an emphasis on prioritizing attributes, such as lightness, portability, and efficiency. In light of the upcoming driverless era, the research focus will be on the development of visual sensors and computer vision technologies that can aid in navigation for the blind.
The visual deficiency can easily help blind and visually impaired people (BVIP) to develop psychological disorders.There are few, if any, devices to meet the outdoor travel needs of BVIP in all aspects.There is no comprehensive summary and overview in the field of outdoor navigation for the blind.The selection of appropriate assistive devices can help BVIP better understand the information of their surroundings and make safer and more effective outdoor trips.
