论文摘要
除了自动驾驶操作外，在许多情况下，希望让人类远程驾驶车辆。为了使远程操作成为可能，至关重要的是，要有低且可预测的延迟来从汽车摄像机传输视频并接收控制命令。在本文中，我们分析了问题，并提出了一个通信和视频流系统，该系统解决了潜伏期挑战，并可以通过市售的LTE网络对真实汽车进行远距离运行；展示了720p，60fps视频的50ms往返潜伏期，平均PSNR 36DB。
In addition to autonomous car operation, in many cases it is desirable to let a human drive the vehicle remotely. To make remote operation possible, it is very critical to have a low and predictable latency to transmit video from the car cameras and receive control commands back. In this paper, we analyze the problem and present a communication and video streaming system that addresses the latency challenges and enables teleoperation of a real car over commercially available LTE network; demonstrating sub-50ms roundtrip latencies for 720p, 60FPS video, with average PSNR 36db.
