After navigational system started, system was with the real-time highway section data on the current display interface of obtaining, and the highway section data comprise the road name of each bar road on the current display interface, shape point, the length on end points coordinate and road.
102, judge one by one whether the road name in the data of said highway section has been presented on the current display interface, if do not have, then execution in step 103;
Obtain after the highway section data on the current display interface, system will judge one by one whether the road name in the data of highway section is presented on the current display interface, and whether decision shows road name according to judged result.
103, confirm the not display location information of road name on current display interface of demonstration according to the highway section data;
When the road title is not presented on the current display interface; System will confirm the display location information of road name on current display interface that do not show, and display location information has been indicated accurately display position and the display mode of road name on current display interface.
104, the road name that will not show is presented on the corresponding position of current display interface.
When the road title was not presented on the current display interface, the display location information corresponding according to road name was presented at the road name that does not show on the corresponding position of current display interface.
In embodiments of the present invention; Through the display location information of judging whether road name has been presented on the current display interface and has passed through to confirm the road name that does not show in the highway section data on the current display interface; Be presented at road name on the current display interface dynamically; Make road name to show dynamically, realized the dynamic demonstration that road name is complete, improved user's experience along with the variation of current display interface.
In order better to understand technology, see also Fig. 2, the embodiment for the dynamic method that shows of a kind of road name of the present invention comprises:
201, confirm the position coordinates of figure on the map that presets on the current display interface;
After navigational system starts; System is with the position coordinates of the figure on the real-time current display interface on the map that presets; The map that presets is a digital navigation map, is a kind of navigation software, and digital navigation map comprises roads all on the map, background, mark and highway section data.
202, from map, obtain the highway section data of the road on the current display interface according to position coordinates;
System confirms after the coordinate position of current display interface on navigation map, will from map, obtain the highway section data of current display interface according to coordinate position.The highway section data comprise the road name of each bar road on the current display interface, shape point, the length of end points coordinate and road;
Need to prove, the shape point that the shape point in the data of highway section comprises for the highway section on current display interface, it possibly comprise all shape points of this road, also possibly be the part among all shape points.The end points coordinate of highway section data is the end points coordinate of road on current display interface, comprises the starting point of this road on current display interface and the coordinate of terminal point, and the length of the road in the data of highway section is the length of road on current display interface.In embodiments of the present invention, if do not have to specify, equal content understandings as described above.
203, extracting data goes out the road name that should show from the highway section.
System obtains will go out the road name that should show from the highway section extracting data after the highway section data on the current display interface.
204, judge one by one whether the road name in the data of said highway section is presented on the current display interface, if, then continue execution in step 204, if not, then execution in step 205;
205, confirm the change direction of corresponding road according to the slope between the coordinate of the road shape point on the current display interface at shape point;
When the road name of certain bar road is not presented on the current display interface; System will further confirm the not concrete display position of the road name of demonstration; When the road title shows on current display interface; System will continue to judge whether the road name of next bar road has been presented on the current display interface, and the road name that in the data of highway section, comprises has all been accomplished deterministic process.
Need to prove; Shape point in the data of highway section has comprised the information of the turning point of a crankcase ventilaton; The shape point of road is used for confirming whether have crankcase ventilaton between starting point and the terminal point of road; If there is not the information of shape point between the starting point of road and the terminal point, confirm that then this road is the straight line road.If certain the bar road on the current display interface does not have the relevant information of shape point; Explain that then this road is the straight line road; When the display location information of the road name that obtains this road; Do not need execution in step 205, step 206 can change to: according to the end points coordinate, and the display location information of the length computation road name on road.
206, calculate the display location information of road name in the change direction of shape point according to the length on end points coordinate, road and road;
System confirms road after the change direction of shape point, with further calculating the display location information that does not show road name.The end points coordinate that system will comprise in the change direction of shape point and highway section data according to road, the display location information of the length computation road name on road.
Wherein, the display location information of road name comprises: show the starting point of road name, show the angle of road name and the length of road name.
207, the road name that will not show is presented on the corresponding position of current display interface.
If the road name in the data of highway section is not presented on the current display interface; Then corresponding display location information according to road name; Road name is presented on the corresponding position of the display location information of this road, thereby guarantees that road on the current display interface all has the road name of corresponding dynamic demonstration.
In embodiments of the present invention; Through processing to the highway section data of the map on the current display interface; Can obtain the display location information of each the bar road name in the data of highway section,, show according to the corresponding road name that shows of the display location information of road name simultaneously again through judging whether the road name that should show on the current display interface shows; Make that road name can complete being presented on the current display interface; And can move accordingly along with the figure on the current display interface and adjust, make road name to be presented at dynamically on the current display interface, improve user's experience.
