【摘要】 众所周知，近年来尤其是进入21世纪，汽车工业已成为世界的支柱产业，汽车在日常生活和工作中起的作用也越来越突出。而如何实现各类车辆的有效指挥、协调控制和管理已经成为交通运输和安全管理部门面临的一个重要问题。 汽车导航系统为汽车司机提供实时的信息服务，使交通网络快速、高效、安全的运行，为提高交通安全和提供良好的交通环境做出了相当的贡献。但现有导航系统这种贡献是有限的，它仅局限于单车导航，并不能从本质上解决现有的交通安全问题，因为它没有分析和解决自车周围潜在的交通问题。 本文正是针对现有汽车导航系统存在的问题和新的发展需要提出新的研究方向——汽车导航信息共享系统(PSS)。PSS实时保持自车与周围车辆的信息共享，并实时提供自车周围信息，特别是容易发生交通事故的信息。PSS包含三个关键技术：创建快速移动无线局域网、实现雷达与摄像机数据匹配，和针对现有的汽车导航CommNavi系统构架不足提出了新的组件思想和系统构架。本文对后两个技术进行了详细论述：在实现雷达与摄像机数据匹配技术中主要给出了方便有效的摄像机标定方法和雷达与摄像机数据匹配算法；在PSS系统构架中针对COM组件在嵌入式系统的不足提出了基于DLL的组件思想，并提出了便于系统功能扩展和组件升级的系统构架方式。 汽车导航PSS的研究是一个系统复杂的工程，它的实现不但更加提高了交通安全水平，减少交通事故发生，更进一步促进ITS的发展。更多还原

【Abstract】 As everyone knows, especially entering 21st century in recent years, the auto industry has already become the pillar industry of the world, it is more and more outstanding that the automobile function in the daily life and work. How to realize the effective conduct and control in harmony and manage of all kinds of vehicles, which already become an important problem that communication and transportation and safe administrative department have faced.Automobile offer real-time information service to drivers by navigation system, make traffic network fast, high-efficient, security running, and make suitable contribution to improve the traffic safety and offer the more traffic environment. But this kind of contribution is limited, it only confines to navigate by own car, which can not solve the existing traffic safely problem in essence. Because it has not analyzed and solved the potential traffic problem around own car.This text just at the problem which existing automobile navigation exists and new development need, and propose the new research direction -Automobile Navigation Public Space System (PSS). PSS keep the information sharing of own car and vehicles around in realtime, and offer the information around of own car in real time, especially apt to the information of the traffic accident take place. PSS includes three pieces of key technology: Establish fast moving wireless LANs, realize data matching of radar and camera, directed against existing Automobile Navigation CommNavi to propose new component thought and systematic framework. Have described last two pieces of technology in detail in this text: Offer the convenient and effective camera’s calibration method and the data matching algorithms of radar and camera; Aim at the shortage of COM application in embedded system to put forward the component method based on DLL among PSS systematic framework, and propose systematic framework ways who is convenient to system function expand and component upgrading.It is complicated and systematic project that the research of the PS S, its realization not only improves the level of traffic safety further, reduces the traffic accident, and more and more promote the development of ITS.更多还原
