This article proposes a wearable assistive system based on artificial intelligence (AI) edge computing techniques to help visually impaired consumers safely use marked crosswalks, or zebra crossings. The proposed wearable assistive system consists of a pair of smart sunglasses, a waist-mounted intelligent device, and an intelligent walking cane (stick). A deep learning technique is adopted for zebra crossing image recognition in real time. Visually impaired consumers need to wear the proposed smart sunglasses and waist-mounted intelligent device and hold the proposed intelligent walking cane when they approach a zebra crossing. When a visually impaired pedestrian reaches a zebra crossing, they will immediately receive a message about the current situation at the crossing and the traffic light signal. Experimental results show that the accuracy of real-time zebra crossing recognition of the proposed system can reach up to 90%.

斑马线交叉口视障行人安全的基于人工智能边缘计算的辅助系统

本文提出了一种基于人工智能（AI）边缘计算技术的可穿戴辅助系统，以帮助视力障碍的消费者安全地使用带有标记的人行横道或斑马线。拟议的可穿戴辅助系统由一副智能太阳镜，一个安装在腰部的智能设备以及一个智能拐杖（拐杖）组成。深度学习技术用于实时斑马线图像识别。视力障碍的消费者在接近斑马线时，需要戴上建议的智能太阳镜和腰部安装的智能设备，并握住建议的智能拐杖。当有视力障碍的行人到达斑马线时，他们将立即收到有关该路口当前情况和交通信号灯的消息。
