The device comprises a positioning module, a comparison module and an added module, wherein the positioning module is used for receiving a positioning signal of the coordinate of a road track of a new path; the comparison module is connected with the positioning module and is used for comparing the coordinate of the road track of the new path with the coordinate of the road track of the existing map; the added module is connected with the comparison module and is used for manufacturing out new path data corresponding to the new path, adding the new path data to the existing map database and replacing the existing database to form a new database. The method comprises the following steps that: (1) the positioning module receives the positioning signal of the coordinate of the road track of the new path; (2) the comparison module compares the coordinate of the road track of the new path with the coordinate of the road track of the existing map; and (3) the added module manufactures out the new path data corresponding to the new path, adds the new path data to the existing map database and replaces the existing database to form the new database.
Description
[Ji Intraoperative field]
The present invention relates to a kind of method improving navigation map, also relate to a kind of device improving navigation map.
[Bei Jing Ji Intraoperative]
The GPS navigation device of prior art has the function of road tracking record (travel track), can be used for tracing record new route, meanwhile, according to multiple gps coordinates of new route, the basis of existing map data can show new route.But, new route can't be included in planning when carrying out navigation programming by the GPS navigation device of prior art, the new route increased only has prompting function, not including new route in guidance path when increasing new route, causing when user next time still cannot accurate navigation through these new routes.
[summary of the invention]
Therefore, object of the present invention is mainly that providing a kind of includes in navigation map by new route, improves the method for navigation map with this.In addition, the present invention also provides a kind of device improving navigation map realizing above-mentioned purpose.
For achieving the above object, the invention provides a kind of method improving navigation map, comprising: locating module, in order to receive the positioning signal of the railroad tracks coordinate of a new route; Contrast module, it is connected with this locating module, in order to the railroad tracks coordinate of this new route and the railroad tracks coordinate of existing map to be contrasted; Newly-increased module, with this contrast model calling, when in a distance range, when the railroad tracks coordinate of this new route does not overlap with the railroad tracks coordinate of existing map, this newly-increased module making goes out should new route data of new route, add these new route data to existing map data base, and replace this existing database and form a new database.
The present invention also provides a kind of device improving navigation map, comprising: (1) locating module receives the positioning signal of the railroad tracks coordinate of new route; (2) contrast module the railroad tracks coordinate of this new route and the railroad tracks coordinate of existing map are contrasted; (3) in a distance range, when the railroad tracks coordinate of this new route does not overlap with the railroad tracks coordinate of existing map, newly-increased module making goes out should new route data of new route, add these new route data to existing map data base, and replace this existing database and form a new database.
Compared to prior art, method and the device thereof improving navigation map of the present invention, makes the new route on navigation map be upgraded in time and perfect, and person easy to use, promotes the thorough property of navigation programming simultaneously.
[accompanying drawing explanation]
Fig. 1 is the connection block diagram improving the device of navigation map of the present invention;
Fig. 2 is the process flow diagram improving the method for navigation map of the present invention.
[embodiment]
Below, by reference to the accompanying drawings, specific embodiments of the invention are elaborated:
The invention provides a kind of device improving navigation map, be located on a guider, refer to Fig. 1, the described device 1 improving navigation map is made up of locating module 11, contrast module 12 and newly-increased module 13, wherein, locating module 11 is in order to receive the positioning signal of the railroad tracks coordinate of a new route; Contrast module 12 is connected with this locating module 11, in order to the railroad tracks coordinate of this new route and the railroad tracks coordinate of existing map to be contrasted; Newly-increased module 13 is connected with this contrast module 12, when in a distance range, when the railroad tracks coordinate of this new route does not overlap with the railroad tracks coordinate of existing map, this newly-increased module 13 is produced should new route data of new route, add these new route data to existing map data base, and replace this existing database and form a new database.
The present invention also provides a kind of method improving navigation map, and refer to Fig. 2, the method comprises the following steps:
21: the positioning signal receiving the railroad tracks coordinate of new route;
22: the railroad tracks coordinate of new route overlaps with the railroad tracks coordinate of existing map? if so, go to step 23, if not, then go to step 24;
23: guider proceeds navigation;
24: retain current location information, calculate distance according to route, judge whether the distance range more than a setting? if not, go to step 23, if so, then go to step 25;
25: continue recording and tracking, when the railroad tracks coordinate of new route overlaps again with the railroad tracks coordinate of existing map, determine the terminal point coordinate of new route;
26: upgrade map data base, form new map.
In the present embodiment, described new route data at least comprise: starting point coordinate, terminal point coordinate, road section length and section title, after described newly-increased module 13 determines the starting point coordinate of this new route, after the distance range (such as in 100m) of a setting, if the railroad tracks coordinate of described new route overlaps again with the railroad tracks coordinate of existing map, then determine terminal point coordinate and the road section length of this new route.
With the present embodiment, described newly-increased module 13 performs by manually starting, or automatically started by described guider and perform, when performing by manually starting, by arranging button on the panel of guider, being pressed by user and assigning instruction, when being automatically performed by guider, by in guider setting when needs more new database time, the central processing unit of guider starts the instruction that newly-increased module 13 performs more new database immediately.
By reference to the accompanying drawings the specific embodiment of the present invention and embodiment are elaborated above, but the present invention is not limited to the above-described embodiment and examples, in the ken that those skilled in the art possess, can also make a variety of changes without departing from the inventive concept of the premise.
