摘要/Abstract

摘要： 仅依靠路网固定设施远不足以实现车、路感知，车载终智能终端含GPS、重力传感、图像等实时多元异构数据，便于与网络系统云端交互，是道路感知有力的补充。为此，文中专题研究了上下文感知内涵、移动摄像的标定手段等，继而设计并实现了基于移动上下文传感的终端系统，包括网络分层架构、数据动态采集、上下文处理、信息发布等。基于上下文感知的移动终端系统具有实时性、易便性、普适性、覆盖盲区等优点，为交通监管、应急处理和公众出行服务提供了重要手段，代表了智能交通ITS的发展方向。

Abstract: With help of smart terminals equipped with multi-sensors, e.g., GPS, Accelerometer, Gyroscope, Camera and so on, the ability of road awareness will dramatically enhanced. In this paper, we discuss the challenge of applying smart terminals to ITS, and introduce a framework of mobile context. Two major function of context-awareness are implemented by our work, the active status awareness and visual higyway road awareness. We also designed a context-awareness based system which realizes data collection, context computing and information distribution. Compared with regular solution, ours is cheaper, more pervasive, and blind spot resistant, which can be widely use in fields of traffic monitoring, emergency response and public transportation services
