Research And Application Of The Automobile Aavigation Public Space System

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.
