| Abstract: | Most of the present vehicle navigation systems perform map data update based on whole version replacement,which causes long update periods,and this can not satisfy the high verisimilitude requirements for navigation electronic map.Aiming at this problem,the paper researches three key techniques of dynamic incremental update for navigation electronic map,and it realizes online incremental update of navigation electronic map and dynamic maintenance of topology structure,which improves the updating efficiency of navigation electronic map. |
