【摘要】：近年來(lái),隨著我國(guó)經(jīng)濟(jì)實(shí)力和人們生活水平的提高,汽車(chē)行業(yè)也迎來(lái)了具大的發(fā)展,據(jù)公安部統(tǒng)計(jì),截止2014年11月27日,全國(guó)擁有汽車(chē)1.54億輛,僅次于美國(guó),居世界第二位。但我國(guó)擁有汽車(chē)駕駛資格證的人數(shù)已經(jīng)達(dá)到2.44億,位居世界第一。從這些數(shù)據(jù)可以看出,國(guó)內(nèi)市場(chǎng)的汽車(chē)市場(chǎng)非常廣闊。與此同時(shí),隨著城市化建設(shè)的推進(jìn),城市發(fā)展速度越來(lái)越快,道路建設(shè)更是呈現(xiàn)出一番日新月異的景象,道路變得越來(lái)越復(fù)雜,數(shù)據(jù)量也變的非常龐大。車(chē)輛的增加和道路的變化使得傳統(tǒng)的地圖已經(jīng)無(wú)法適應(yīng),由此新一代汽車(chē)導(dǎo)航技術(shù)產(chǎn)生了,它集成通信、電子、導(dǎo)航、互聯(lián)網(wǎng)、安全等多個(gè)領(lǐng)域,形成新的智能化汽車(chē)導(dǎo)航系統(tǒng)。地圖數(shù)據(jù)作為導(dǎo)航系統(tǒng)中不可缺少的一部分,也迎來(lái)了新的挑戰(zhàn)。汽車(chē)導(dǎo)航當(dāng)前最為常用的兩個(gè)功能是電子狗和經(jīng)路計(jì)算,但隨著智能化汽車(chē)的到來(lái),以及電子產(chǎn)品的更新?lián)Q代,未來(lái)汽車(chē)對(duì)于ADAS、DTM、衛(wèi)星圖等數(shù)據(jù)的依賴(lài)會(huì)越來(lái)越多,智能安全距離檢測(cè)、智能輔助泊車(chē)等輔助駕駛技術(shù)以及自動(dòng)化駕駛技術(shù)的發(fā)展,對(duì)汽車(chē)導(dǎo)航地圖的要求會(huì)越來(lái)越高。同時(shí)導(dǎo)航地圖的功能越多,地圖的數(shù)據(jù)量就越大,導(dǎo)航地圖更新帶來(lái)了一定的困難,當(dāng)前導(dǎo)航地圖主要有兩種更新方式,一是全數(shù)據(jù)更新,二是按照區(qū)域進(jìn)行局部更新,但無(wú)論哪一種更新方式數(shù)據(jù)量都比較大。由于當(dāng)前通信網(wǎng)絡(luò)發(fā)展速度很快,4G網(wǎng)絡(luò)也逐漸普及,網(wǎng)絡(luò)速度提升非�？�,導(dǎo)航地圖的更新都是通過(guò)網(wǎng)絡(luò)進(jìn)行傳輸,地圖更新包的大小對(duì)于導(dǎo)航體驗(yàn)有非常大的影響。NDS格式可以很好的解決以上提出的問(wèn)題,由于NDS數(shù)據(jù)以數(shù)據(jù)庫(kù)的形式存儲(chǔ)的,所以NDS可以很好的解決差分更新問(wèn)題。同時(shí)NDS格式是全球各大汽車(chē)廠商和地圖廠商聯(lián)合制定的導(dǎo)航地圖格式,NDS也成為下一代汽車(chē)導(dǎo)航主要使用的地圖格式。本文闡述了以Shape數(shù)據(jù)為輸入,轉(zhuǎn)換NDS地圖顯示數(shù)據(jù)的設(shè)計(jì)、構(gòu)建和實(shí)現(xiàn)過(guò)程。主要從研究意義、開(kāi)發(fā)手段、理論技術(shù)、系統(tǒng)需求、總體設(shè)計(jì)、系統(tǒng)實(shí)現(xiàn)與測(cè)試等幾個(gè)方面對(duì)系統(tǒng)進(jìn)行論述。實(shí)現(xiàn)了從Shape轉(zhuǎn)換制作NDS數(shù)據(jù)的目的。
[Abstract]:In recent years, with the improvement of China's economic strength and people's living standards, the automobile industry has also ushered in a great development. According to the statistics of the Ministry of Public Security, as of November 27, 2014, the country has 154 million cars, which is second only to the United States and ranks second in the world. However, the number of people with driving qualifications has reached 244 million, ranking first in the world. From these data, we can see that the domestic market car market is very broad. At the same time, with the development of urbanization, the speed of urban development is getting faster and faster, the road construction is showing a scene of rapid change, the road becomes more and more complex, and the amount of data becomes very large. With the increase of vehicles and the change of roads, the traditional map has been unable to adapt, so a new generation of automobile navigation technology has emerged, which integrates many fields, such as communication, electronics, navigation, Internet, security, etc. Form a new intelligent automobile navigation system. Map data, as an indispensable part of navigation system, has also ushered in new challenges. At present, the two most commonly used functions of automobile navigation are electronic dog and path calculation. But with the arrival of intelligent vehicles and the upgrading of electronic products, the future automobile will rely more and more on ADASS DTM, satellite images and other data. With the development of intelligent safe distance detection, intelligent assisted parking and automatic driving technology, the requirements of vehicle navigation map will be higher and higher. At the same time, the more functions of the navigation map, the larger the data volume of the map, and the difficulty of updating the navigation map. At present, there are two main ways of updating the navigation map, one is to update the whole data, the other is to update the map locally according to the area. However, no matter which way of updating data is relatively large. Due to the rapid development of the communication network and the gradual popularization of the 4G network, the speed of the network is rising very quickly, and the update of the navigation map is transmitted through the network. The size of map update package has a great impact on the navigation experience. NDS format can solve the above problems well. Because the NDS data is stored in the form of database, NDS can solve the differential update problem very well. At the same time, the NDS format, which is developed jointly by the major automobile manufacturers and map manufacturers, has become the main map format for the next generation of automobile navigation. This paper describes the design, construction and implementation of transforming NDS map display data with Shape data input. This paper mainly discusses the system from the aspects of research significance, development means, theory and technology, system requirements, overall design, system implementation and testing. The purpose of making NDS data from Shape conversion is realized.
