This article pays attention to make use of curve matching to correct the distance error of dead - reckoning. matching algorithm improved by woleson is dependent on redrawing characteristic point and corresponding relation
Woleson等人提出的曲線匹配演算法,在很大程度上依賴于特徵點的提取和特徵點的對應。 -
In the management of city transportation, navigation of satellite cannot meet the practical requirement because of shielding and interfering of satellite signal. therefore, map matching and dead - reckoning ( dr ) is used to assistant navigation. this combination is defined as gps / dr integrated navigation system, in which the map matching is used for correcting the orientation and distance errors of dr
而在城市交通管理的應用中,由於衛星定位信號經常會受到建築物的遮擋和干擾,衛星定位無法滿足導航的實際要求,通常需用地圖匹配和航位推算器( dead - reckoning , dr )的方法進行輔助導航,這種導航方式稱為組合導航系統,其中地圖匹配可用來修正dr的方向和距離的系統誤差,以便在衛星信號失鎖時,提高dr自主定位的精度。
