Map - matching algorithm based on topological structure adaptive fuzzy decision 自適應(yīng)模糊決策的地圖匹配算法
In this paper , aimed at the map - matching based global localization of lrv , digital lunar map reconstruction techniques are studied , some methods are proposed and implemented 本文面向基于地圖匹配的月球車全局定位問題,研究了月面三維地圖重建的相關(guān)技術(shù)。
In recent years , it has become important in the field of vehicle navigation system how to integrate gps technology with decd reckoning system and map - matching system . at first , this paper introduced research and using status of vehicle navigation system in national and oversea 近年來,如何使gps定位技術(shù)與dr航位推算系統(tǒng)及mm地圖匹配系統(tǒng)更好的結(jié)合起來已成為車輛導(dǎo)航系統(tǒng)研究中的一個重要內(nèi)容。
The position system has used to give first place to with gps navigates , dead reckoning system and map - matching system are the subdominant ones . the location is calculated by dead reckoning algorithm when the gps system invalidated which can affact well in short time 定位系統(tǒng)采用了與gps為主、航位推算系統(tǒng)為輔的組合導(dǎo)航系統(tǒng),利用航位推算對gps定位出現(xiàn)失效時,進行輔助定位,在短時間內(nèi)能獲得良好的效果。
The localization scheme based on matching between the global and the local lunar maps is of great importance for the global localization . in the map - matching based localization scheme , one of the key problem is the mapping according to the lunar images acquired both on - orbit and on - vehicle 基于全局地圖與局部地圖匹配實現(xiàn)定位,將對解決月球車全局定位問題具有重要意義,其中一個關(guān)鍵問題是如何利用月面航拍圖像和月球車車載攝像機拍攝的圖像建立月面數(shù)字地圖。
