Navigation method and system

Abstract

The invention relates to a method and system of navigation. The method comprises: obtaining the direction of the path which belongs to a current position of a navigation device recognized by an electronic map; calculating the path from a start point to a destination point and generating the path direction according to the information of the start point and destination point by the electronic map; calculating a deviation angle between the path direction and the reference direction selected by the electronic map; determining the real due south direction by a compass module of the navigation device; and generating the directional information at present position according to the deviation angle and the real due south direction. The method and system of navigation can fully use the path of the present electronic map and the calculating function of the path direction, determine the real due south direction by the compass module, effectively combine the electronic map and the function of the compass module to obtain the real direction, provide the rapid and accurate navigation service for the users, save time of finding the real direction repeatedly according to the electronic map by the users, and have great benefit for the users having poor direction-sense especially.

Description

technical field [0001] The invention relates to the application field of electronic maps, in particular to a navigation method and system. Background technique [0002] Electronic map (Electronic map), that is, digital map, is a map that is stored and consulted digitally using computer technology. The method of storing information in electronic maps generally uses vector image storage. The scale of the map can be enlarged, reduced or rotated without affecting the display effect. In the early days, bitmap storage was used, and the scale of the map cannot be enlarged or reduced. Modern electronic map software generally uses geographical information systems to store and transmit map data, and other information systems. Electronic maps can be used to find various places and locations, and can also find some travel routes and realize navigation through the map. Navigation is the method of guiding a device from one point to another on a specified course. With the development of...

Problems solved by technology

[0003] Although most of the current electronic maps have navigation functions, they can only plan the route and provide the direction of the route. The user cannot determine the actual direction of the current location, and must repeatedly find the correct direction according to the position of the map. Strong users are even more challenging, so there are still many problems when using the navigation function of the existing electronic map
