Navigation data processing method, device and navigation terminal

Abstract

The invention discloses a navigation data processing method, a navigation data processing device and a navigation terminal. A specific execution mode of the method is implemented through the following steps: acquiring trajectory information and positioning information of a navigation system; extracting non-navigation-data trajectory information in the trajectory information; determining trajectory linkage information corresponding to the non-navigation-data trajectory information based on the positioning information; according to the trajectory linkage information, judging whether the non-navigation-data trajectory information corresponds to new road network data; and if so, processing the non-navigation-data trajectory information so as to obtain the new road network data corresponding to the non-navigation-data trajectory information, and adding the new road network data into a navigation database so as to update navigation data. Due to the adoption of the execution mode, the rapid and automatic updating of navigation data can be realized. The discovery cycle of new road network data can be effectively shortened, and meanwhile, the accuracy of the acquired new road network data also can be guaranteed.

Description

technical field [0001] The present application relates to the technical field of navigation, in particular to the technical field of electronic terminal navigation, and in particular to a navigation data processing method, device and navigation terminal. Background technique [0002] At present, the main method of making and updating navigation electronic map data is to manually collect information on the spot, and then perform information processing to generate data for updating the navigation system. Another way to make a navigation electronic map is to use aerial photography and satellite imagery to obtain navigation data, but this method is generally used to correct deviations. Another method for updating the navigation electronic map is to collect new road information fed back by navigation users, and obtain data for updating after verifying the feedback information. [0003] The above prior art has the following problems: the biggest disadvantage of the manual collect...

AI Technical Summary

Problems solved by technology

[0003] The above existing technologies have the following problems: the biggest disadvantage of the manual collection method is that the period from data collection to production and putting into use is too long

For some roads that users frequently drive, such as bridges and expressways, if the navigation data of these roads is missing, the navigation system will plan unreasonable routes and reduce the accuracy and reliability of the navigation system.

Aerial and satellite imagery Figure 1 Generally used as an auxiliary verification method, the obtained data cannot be used as the standard of road data

The current method of updating navigation data based on user feedback is not mature enough, and the quality of user feedback information is uneven, and a lot of work is needed to select and identify to ensure the accuracy of information

In addition, the above methods require manual operation to ensure the accuracy of the navigation data, and the automatic update of the navigation data cannot be realized.
