Abstract
The present invention provides a kind of methods of Auto-matching up-to-date map in navigation procedure, include the following steps: 1) to set destination in navigation；2) navigation data for guiding navigation object to reach setting destination is searched according to the navigation routine information of navigation object in electronic map database by navigation module；3) while navigation object is mobile, generation module is updated by road net data and records the dynamic trajectory that navigation object currently moves, as current road net data；4) by current road net data, original road net data compares in electronic map, obtains comparison result；If data comparison result is that the two is mutually internally inconsistent, i.e., current road net data is newly, then the current road net data to be stored in electronic map database, to increase the road net data information content of electronic map in electronic map database newly；If data comparison result is that the two is unanimously, to complete navigation task under the guide of navigation module.The method of Auto-matching up-to-date map in a kind of navigation procedure described in this patent realizes and automatically updates to electronic map road net data, can effectively prevent navigational error during navigation object is mobile.
Description
Technical field
It, can be in the method for map automatic updating information in espespecially a kind of GPS navigation the present invention relates to map updating method.
Background technique
The update mode of electronic map applied in GPS navigation system is mostly passive type at present, generally by
Tripartite needs user in a wireless or wired way by the advanced map information delivery updated into the carrier that electronic map is housed
Regularly software upgrading automatically is done to electronic map, and for rural area, the lower road of Some Soils For Vegetable Cultivation In Urban Areas rank, there are also some inclined
Out-of-the-way path or the recently road in construction often do not indicate complete detailed geodata in electronic map, to help
Help others complete navigation task.
Summary of the invention
To solve the above problems, the present invention provides a kind of methods of map automatic updating information in GPS navigation, including with
Lower step:
Step 1) sets destination in navigation；
Step 2), which is searched in electronic map database by navigation module according to the navigation routine information of navigation object, to be referred to
Draw the navigation data that navigation object reaches setting destination；
Step 3) updates generation module by road net data and records navigation object when Forward while navigation object is mobile
Dynamic dynamic trajectory, as current road net data；
By current road net data, original road net data in electronic map compares step 4), obtains comparison result；If
Data comparison result is that the two is mutually internally inconsistent, i.e., current road net data is newly, then the current road net data to be stored in electricity
In sub- map data base, to increase the road net data information content of electronic map in electronic map database newly；In the present invention, institute
Stating road net data includes one of road information, region building information and traffic information or a variety of.The navigation pack
Include the distance between navigation path associated with navigation object and any reference object, direction guide, traffic information and height above sea level
One of height is a variety of.
Compared with prior art, navigation system of the invention is remembered using GPS positioning technology while navigation object is mobile
The running track for recording lower navigation object, after analyzing running track, by its with the road net data that is stored in electronic map into
Row compares, and is increased newly navigation object running track as new road net data to the electricity of navigation system according to comparison result judgement
In sub- map, to realize the mesh for automatically updating or increasing electronic map road net data during navigation object is mobile
, enable map more fully, accurately.
Specific embodiment
A kind of method of map automatic updating information in GPS navigation, comprising the following steps:
1, destination is set in navigation；
2, guide is searched according to the navigation routine information of navigation object in electronic map database 1 by navigation module 2
Navigation object reaches the navigation data of setting destination；
3, while navigation object is mobile, the record navigation object of generation module 3 is updated by road net data and is currently moved
Dynamic trajectory, as current road net data；
4, by current road net data, original road net data compares in electronic map, obtains comparison result；If data
Comparison result is that the two is mutually internally inconsistent, i.e., current road net data is newly, to be then stored in the current road net data electronically
In chart database 1, to increase the road net data information content of electronic map in electronic map database 1 newly；If data comparison result
It is unanimously, then to complete navigation task under the guide of navigation module 2 for the two.
The above-described embodiments are merely illustrative of preferred embodiments of the present invention, not to model of the invention
It encloses and is defined, without departing from the spirit of the design of the present invention, this field ordinary engineering and technical personnel is to the technology of the present invention side
The various changes and improvements that case is made, should fall within the scope of protection determined by the claims of the present invention.
Claims (1)
1. a kind of method of GPS navigation map automatic updating information, which comprises the following steps:
1) destination is set in navigation；
2) guide navigation pair is searched according to the navigation routine information of navigation object in electronic map database by navigation module
Navigation data as reaching setting destination；
3) while navigation object is mobile, generation module is updated by road net data and records the dynamic that navigation object currently moves
Track, as current road net data；
4) by current road net data, original road net data compares in electronic map, obtains comparison result；If data compare
As a result mutually internally inconsistent for the two, i.e., current road net data is newly, then the current road net data to be stored in electronic map number
According in library, thus in newly-increased electronic map database electronic map road net data information content；If data comparison result is the two
To be consistent, then navigation task is completed under the guide of navigation module.
