视障人士在室内环境中的智能引导眼镜

Smart Guiding Glasses for Visually Impaired People in Indoor Environment

Jinqiang Bai, Shiguo Lian, Zhaoxiang Liu, Kai Wang, Dijun Liu

摘要:

为了解决视障人群出行困难的问题,本文提出了一种新型的眼镜形智能引导装置--ETA(Electronic Travel Aids),用于为视障人群提供高效、安全的引导。与现有的避障算法不同,提出了一种基于多传感器融合的避障算法,该算法利用深度传感器和超声波传感器来解决小障碍物和透明障碍物(如法式门)的检测问题。对于完全失明的人,开发了三种听觉线索来告知他们可以前进的方向。而对于视力较弱的人,视觉增强,利用增强现实(AR)技术和整合的遍历方向。研制了由一副显示眼镜和几个低成本传感器组成的原型,并通过大量用户测试了其效率和准确性。实验结果表明,该智能导航眼镜能有效改善用户在复杂室内环境中的出行体验。因此,它可以作为一种消费设备,帮助视障人士安全旅行。

英文摘要:

To overcome the travelling difficulty for the visually impaired group, this paper presents a novel ETA (Electronic Travel Aids)-smart guiding device in the shape of a pair of eyeglasses for giving these people guidance efficiently and safely. Different from existing works, a novel multi sensor fusion based obstacle avoiding algorithm is proposed, which utilizes both the depth sensor and ultrasonic sensor to solve the problems of detecting small obstacles, and transparent obstacles, e.g. the French door. For totally blind people, three kinds of auditory cues were developed to inform the direction where they can go ahead. Whereas for weak sighted people, visual enhancement which leverages the AR (Augment Reality) technique and integrates the traversable direction is adopted. The prototype consisting of a pair of display glasses and several low cost sensors is developed, and its efficiency and accuracy were tested by a number of users. The experimental results show that the smart guiding glasses can effectively improve the user's travelling experience in complicated indoor environment. Thus it serves as a consumer device for helping the visually impaired people to travel safely.
