【摘要】：隨著智能手機(jī)的不斷普及和移動(dòng)終端定位技術(shù)、3G通信網(wǎng)絡(luò)的快速發(fā)展，傳統(tǒng)的以單機(jī)或者網(wǎng)頁(yè)方式實(shí)現(xiàn)的地圖服務(wù)已經(jīng)難以滿足用戶的需求，在ipad，iphone，，Android等移動(dòng)終端上提供基于位置的移動(dòng)地圖服務(wù)已經(jīng)成為一股潮流。移動(dòng)地圖服是基于位置服務(wù)（LBS)的應(yīng)用，獲得用戶的準(zhǔn)確位置信息是為用戶提供服務(wù)的前提。受困于GPS信號(hào)穿透力弱，易受到建筑物、樹木等的阻擋，GPS在室內(nèi)無法定位以及定位速度慢的缺陷一直為人們所詬�。慌c此同時(shí)，相當(dāng)一部分中低端智能手機(jī)并沒有GPS芯片，采用基站定位的精度誤差往往都是幾百米，甚至幾公里；另一方面，當(dāng)前的移動(dòng)地圖服務(wù)應(yīng)用基本都使用在線地圖服務(wù)，移動(dòng)設(shè)備在無法WiFi網(wǎng)連接的情況下，加載地圖數(shù)據(jù)不僅耗時(shí)耗流量，在國(guó)外旅行時(shí)甚至無法使用移動(dòng)地圖服務(wù)應(yīng)用。 針對(duì)目前移動(dòng)地圖服務(wù)應(yīng)用中存在的定位缺陷和使用在線移動(dòng)地圖服務(wù)的問題，本文使用Eclipse、ADT、Java開發(fā)工具語言和Android SDK、ksoap-Android等開發(fā)包在Android平臺(tái)上設(shè)計(jì)并開發(fā)了一個(gè)移動(dòng)個(gè)人出行助手應(yīng)用。Android個(gè)人出行助手支持離線矢量地圖和離線Google Maps，實(shí)現(xiàn)了移動(dòng)地圖服務(wù)的無縫切換，為用戶解決了使用在線地圖服務(wù)耗時(shí)耗流量的問題。Android個(gè)人出行助手采用多種定位方法結(jié)合的混合定位模式，并采用了坐標(biāo)糾偏機(jī)制，一定程度上解決了移動(dòng)終端定位精度低和定位速度緩慢的問題。與此同時(shí)，Android個(gè)人出行助手還為用戶的出行提供路徑查詢、地址查詢、天氣預(yù)報(bào)、蹤跡記錄、定位跟蹤等服務(wù)，可以為用戶的出行提供便利。
[Abstract]:With the continuous popularization of smart phones and the rapid development of 3G communication network, the traditional map service realized by single computer or web page has been difficult to meet the needs of users. Providing location-based mobile map services on mobile devices such as iPad iPhone Android has become a trend. Mobile map service is an application based on location service (LBS). It is a prerequisite for users to obtain accurate location information. Trapped by weak penetration of GPS signals, vulnerable to buildings, trees, and other barriers to GPS's inability to locate indoors and its slow speed, many low-end smartphones do not have GPS chips. The accuracy error of using base station positioning is often several hundred meters or even several kilometers. On the other hand, the current mobile map service applications basically use online map services, mobile devices can not be connected to the WiFi network, Loading map data is not only time-consuming and time-consuming, but also unable to use mobile map service when traveling abroad. In view of the localization defects in the current mobile map service application and the problems of using the online mobile map service, In this paper, we design and develop a mobile personal travel assistant application .Android personal Travel Assistant to support off-line vector map and offline Google Mapsbased on Android platform by using Eclipse ADT Java development tool language and Android SDK ksoap-Android development kit, which realizes seamless switching of mobile map service. The problem of using online map service is solved. Android personal travel assistant adopts a mixed location mode which combines multiple positioning methods, and adopts coordinate correction mechanism. To some extent, the problem of low positioning accuracy and slow positioning speed of mobile terminal is solved. At the same time, Android personal travel assistant also provides path query, address query, weather forecast, track record, location tracking and other services, which can provide convenience for users to travel.
