Positioning navigation method, map query system and positioning navigation system

定位导航方法、地图查询系统和定位导航系统

Abstract

本发明提供一种定位导航方法、地图查询系统和定位导航系统。该方法包括地图查询系统接收位于导航区域内的移动终端通过通信网络发送的路径查询请求,路径查询请求是移动终端根据预定的路径查询规则构造的,路径查询请求包括起始位置和目的位置所分别对应的查询编号;地图查询系统根据查询编号,在三维立体地图数据库中查询导航路径信息,并根据导航路径信息生成三维导航图形,以彩信的方式返回。本发明为一特定的区域大型建筑物尤其是具有多层结构的建筑专门配备一地图查询系统,基于该地图查询系统为用户提供具有三维效果的导航图形,针对该建筑专门提供其内部的导航处理解决方案,满足了内部短距离、高精确度的定位导航需求。
The invention provides a positioning navigation method, a map query system and a positioning navigation system. The method comprises the following steps: the map query system receives a path query request which is sent by a mobile terminal positioned in a navigation region through a communication network, wherein the path query request is constructed by the mobile terminal according to the preset path query rules, and the path query request comprises query numbers which respectively correspond to an initial position and a destination position; and the map query system queries the navigation path information in a three-dimensional map database according to the query numbers, generates a three-dimensional navigation chart according to the navigation path information, and returns the three-dimensional navigation chart in a mode of a multimedia message. The invention specially provides a map query system for a large building and especially a building with a multilayer structure in a specific region, a navigation chart with a three-dimensional effect is provided for a user based on the map query system, and a navigation treatment solution of the inner part of the building, which aims at the building is specially provided, thereby meeting the positioning navigation requirements of short distance and high accuracy of the inner part.
