摘要:

近年来,旨在提升交通系统安全性的自动驾驶汽车(AV)技术发展显著加快。尽管自动驾驶汽车已在现实世界中得到一定程度部署,但大规模部署仍要求自动驾驶汽车能够稳健应对暴雨、降雪、低光照、施工区域以及隧道内GPS信号丢失等挑战。为了能够处理这些特定挑战,自动驾驶汽车必须可靠地识别其运行环境的物理属性。在本文中,我们将上下文识别定义为准确识别环境属性以便自动驾驶汽车妥善应对的任务。具体而言,我们定义了24种环境上下文,涵盖自动驾驶汽车必须感知的多种天气、光照、交通和道路状况。出于识别环境上下文的需求,我们创建了一个名为DrivingContexts的上下文识别数据集,包含超过160万个与自动驾驶汽车相关的上下文-查询对。由于传统的监督式计算机视觉方法难以良好扩展到多样化的上下文,我们提出了一个名为ContextVLM的框架,该框架利用视觉语言模型通过零样本和少样本方法检测上下文。ContextVLM能够以超过95%的准确率可靠地检测相关驾驶上下文,同时在自动驾驶汽车上搭载的4GB Nvidia GeForce GTX 1050 Ti GPU上实时运行,每个查询的延迟为10.5毫秒。

英文摘要:

In recent years, there has been a notable increase in the development of autonomous vehicle (AV) technologies aimed at improving safety in transportation systems. While AVs have been deployed in the real-world to some extent, a full-scale deployment requires AVs to robustly navigate through challenges like heavy rain, snow, low lighting, construction zones and GPS signal loss in tunnels. To be able to handle these specific challenges, an AV must reliably recognize the physical attributes of the environment in which it operates. In this paper, we define context recognition as the task of accurately identifying environmental attributes for an AV to appropriately deal with them. Specifically, we define 24 environmental contexts capturing a variety of weather, lighting, traffic and road conditions that an AV must be aware of. Motivated by the need to recognize environmental contexts, we create a context recognition dataset called DrivingContexts with more than 1.6 million context-query pairs relevant for an AV. Since traditional supervised computer vision approaches do not scale well to a variety of contexts, we propose a framework called ContextVLM that uses vision-language models to detect contexts using zero- and few-shot approaches. ContextVLM is capable of reliably detecting relevant driving contexts with an accuracy of more than 95% on our dataset, while running in real-time on a 4GB Nvidia GeForce GTX 1050 Ti GPU on an AV with a latency of 10.5 ms per query.
