navi navi 中文意思是什麼

This paper, reviews the development history of autonomous navigation system - navistar 2001, and illustrated that it has great importance to the modernization of traffic of our country to research and develop self - designed navigation system. at the same time, this paper give the prototype of navigation system navi - star2001 as a example and discusses specially several aspest of the research and development : 1. the structure design and module function assignmeng of the system ; 2. the realiztion method of the module mapdisplay, routecalculate and routeguide ; 3. the design of properly structured data storage structure which can reflect the complex road network in reality ; 4

同時，本文還以自主式導航系統原型navi - star2001為例子，重點論述了我們在進行navi - star2001開發過程中所作的下面幾個工作： 1 、 navi - star2001的系統結構設計及模塊劃分，各模塊的功能分配，這部分工作從整體上對自主式導航系統進行了規劃，對于自主式導航系統這樣復雜系統的開發工作來說，具有重要意義； 2 、地圖顯示、路徑規劃、路徑引導的實現方法、關鍵技術； 3 、設計一個結構合理，能夠準確反映真實道路網路的數據存儲結構，按照這個存儲結構組織起來的道路網數據構成了系統中導航功能的數據基礎； 4 、設計車輛定位模塊中的道路分塊索引技術、 gps數據的接收處理方法及三段式道路匹配演算法，這三部分緊密配合實現了移動車輛實時準確的定位。

This thesis is based on the research of car - navi infromation system which is fund by ministry of information industry ( mii ). the thesis describes the design of embedded system for mpc5200, and study function reduce technology, real time improvement technology and quicklaunch mechanism of embedded qt in embedded system development

結合國家信息產業部基金項目「車載信息系統」 ，本文通過基於嵌入式處理器mpc5200的嵌入式系統設計，研究了嵌入式linux系統開發中的函數級裁剪技術、 linux實時性改進技術和嵌入式qt下的quicklaunch機制。
