Texting while driving can be deadly. Talking on the phone while walking is also deadly, or at least threatening enough. Researchers at Dartmouth College in America and the University of Bologna in Italy thought it necessary to develop a smartphone app that can make those things safer.
开车时发短信可能招致性命之忧,走路时打电话同样会致命,至少这样做是非常危险的。来自美国达特茅斯学院和意大利博洛尼亚大学的研究人员认为有必要开发一款智能手机应用程序,让上述事情变得更为安全。
Their Android app uses machine learning and image recognition, which takes place right on your phone to alert you when you're chatting your way right into an oncoming smash-up.
他们所开发的安卓系统应用程序使用机器学习和图像识别技术。当重大交通事故即将发生时,该程序会在你的手机上发出警报,提醒正在聊天的你。
The app uses the outward facing camera on a smartphone to help a pedestrian look both ways (at least one way). Using vision algorithms built into the app, the system determines which way cars on the roadway are facing and whether or not they are moving. Then it takes into account the tilt of the phone and varies light conditions to establish an accurate picture of the roadway. Therefore, it figures out if any approaching vehicle is a threat to the user.
该程序借助智能手机的外置摄像头帮助行人观察左右两侧的路况(至少是一侧)。系统可以利用程序中的视觉计算公式来判断路上车辆行驶的方向和它们的行驶状况。然后系统将考虑手机的倾斜程度,调节光线,形成路面交通状况的真实图像,由此推断正在靠近的任何车辆是否会对机主造成威胁。
