Embodiment Construction

[0019] In order to make the objectives, technical solutions, and advantages of the present invention clearer, the following further describes the present invention in detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, but not to limit the present invention.

[0020] figure 1 The implementation process of the method for updating navigation data provided by the embodiment of the present invention is shown, and the detailed steps are as follows:

[0021] In step S101, it is determined whether it is necessary to customize a new road according to the road composition information, if yes, execute step S102, otherwise, it ends.

[0022] In the embodiment of the present invention, the criterion for this judgment is whether the road composition information of the road segment currently walking by the user is inconsistent with the road segment information i...

Abstract

The invention is applicable to the navigation field and provides a navigation data updating method and a system thereof, and a navigation device, the method comprises the following steps: a newly built road is generated according to road composition information; correction of attribute data of nodes of the newly built road is carried out; the newly built road and the attribute data of the nodes after the correction are updated to a navigation map database. In the invention, the generated newly built road, the attribute data for carrying out the correction of the nodes of the newly built road and a MARK point are updated to the navigation map database, and the related data in the navigation map database is timely updated, thereby facilitating use of users.

Description

Technical field [0001] The invention belongs to the field of navigation, and in particular relates to a method, system and navigation device for updating navigation data. Background technique [0002] At present, the map data for navigation comes from a professional map data company. The map data company generally updates the database every six months, and then embeds the database into the navigation device. The map data that users can really use is at least delayed than the actual road conditions. Nearly a year. [0003] At present, in the navigation process, the road elements or turning elements that do not match the actual traffic conditions are selected, the traffic information is modified and a dynamic map topology information is generated and saved in the dynamic topology information database; when starting to calculate the route, the navigation calculation After the server loads the static map topology data, the dynamic topology information is reloaded; if the road element...
