Chris Urmson: 无人驾驶汽车是怎样看世界的 How a driverless car sees the road

Chris Urmson是谷歌无人车项目的负责人,而近期发布的最新一代无人车正在山景城的道路上进行着测试。而对于普通民众而言,他们更想了解的是这些车辆是如何在没有人工干预的情况下实现自主驾驶的。Urmson在TED的讲座中通俗地阐述了这个问题。视频值得一看。国内读者需要自行翻墙。

Chris Urmson is head of the self-driving car project at Google. The company just announced that the latest prototype of its car is now on the roads of Mountain View. But one thing that many just can’t wrap their head around is how these cars can manage to navigate the roads themselves, without any human assistance. Urmson does a great job of explaining that in this TED Talk video, worth watching.

讲座以汽车安全的历史简介为开始,并指出驾驶员的操作失误是交通事故的最大原因。2009年左右,谷歌的无人车主要是在高速路上行驶,仅仅需要对周边车辆与本车实现几何关系的理解。现在,在城区环境中,车的周围存在着大量的物体:路上的鸭子、闯红灯的自行车、不断违反交规的驾驶员等等,而这些正是谷歌无人车面临的新挑战。

He starts off by giving a brief history of the safety of cars, and their biggest “bug,” the human that controls them. Back in 2009, the cars were driving primarily on highways, where they only need to have a basic geometric understanding of the cars around them and their environment. Now, however, the cars are driving in neighborhoods where there are an almost infinite number of variables. Ducks in the road, bicyclists running red lights, and drivers breaking dozens of traffic rules are the just the beginning of what the cars are now experiencing.
