Method and system for obtaining positioning and navigation information

Abstract

The invention provides a method and system for acquiring positioning and navigation information. An electronic base map of an orienteering map is acquired, and at least two position point identifiers,corresponding to at least two position points through which a user passes, in the electronic base map and GPS coordinates of the at least two position points are acquired; the incidence relation between the at least two position point coordinates and the GPS coordinates of the at least two position points is established; the positioning and navigation information of all the position point identifiers in the electronic base map is acquired according to the incidence relation between the at least two position point coordinates and the GPS coordinates of the at least two position points. Positioning and navigation functions of orienteering sites and other large complex regions and outdoor scenes are achieved.

Description

technical field [0001] The present invention relates to the field of information processing, and more particularly, to a method and system for acquiring positioning and navigation information. Background technique [0002] Orienteering as a new sport is attracting more and more people all over the world. In the process of orienteering, the most serious problem is the loss of direction. For example, when going off-road in the mountains and forests, the most taboo is to rush to take a "shortcut" before the degree of directional error and the correct direction of travel have not yet been identified. , this is likely to cause circles in place and delay the game time. [0003] However, the currently commonly used mobile phone map software does not provide detailed maps of the outdoors, forests, villages, etc., and cannot provide accurate positioning. Moreover, most of the orienteering sites are in areas with poor network conditions, and it is impossible to access the network in ...

AI Technical Summary

Problems solved by technology

In the process of orienteering, the most serious problem is getting lost in the direction. For example, when going off-road in the mountains and forests, the most taboo is to take a "shortcut" in a hurry before finding out the degree of direction error and the correct direction of travel. , this is likely to result in going around in circles and delaying the game time

[0003] However, the currently commonly used mobile phone map software does not provide detailed maps of outdoors, forests, villages, etc., and cannot provide accurate positioning. Moreover, most of the orienteering sites are in areas with poor network conditions, and it is impossible to access them from the network in real time. terminal to obtain map data

At present, there is no positioning and navigation solution for large and complex areas and outdoor scenes such as orienteering venues
