论文摘要
这项工作介绍了卫报天使，这是一个Android应用程序，可帮助视力障碍者避免在复杂的交通环境中危险。该系统由预贴Yolo模型，距离估计和移动方向估算组成，可提供有关周围车辆的信息，并警报使用潜在危险的使用者，而没有昂贵的特殊用途设备。通过对8个受试者进行的实验，我们证实了在行人交叉实验中使用智能手机的帮助的满意度得分比没有99％置信度以下的智能手机的帮助更好。但是，在我们的系统的辅助下，越过道路所需的时间平均要短，但是我们的实验并没有达到显着差异。该应用程序已在Google Play商店中发布，免费向公众开放。
This work introduces Guardian Angel, an Android App that assists visually impaired people to avoid danger in complex traffic environment. The system, consisting of object detection by pretrained YOLO model, distance estimation and moving direction estimation, provides information about surrounding vehicles and alarms users of potential danger without expensive special purpose device. With an experiment of 8 subjects, we corroborate that in terms of satisfaction score in pedestrian-crossing experiment with the assistance of our App using a smartphone is better than when without under 99% confidence level. The time needed to cross a road is shorter on average with the assistance of our system, however, not reaching significant difference by our experiment. The App has been released in Google Play Store, open to the public for free.
