The method of the embodiment of the invention includes the following steps: when a complex intersection exists within a preset scope from the current location of a user, judging whether picture data corresponding to the complex intersection exist in a navigation map, if yes, displaying the picture data corresponding to the complex intersection, and if not, reading complex intersection-corresponding map data in the navigation map; according to the map data and a preset scale, drawing an enlarged intersection map corresponding to the complex intersection; and displaying the enlarged intersection map. The embodiment of the invention can effectively and flexibly display complex intersections and increase the processing efficiency of navigation equipment.
Description
Technical field
The present invention relates to the applied technical field in the navigation map, relate in particular to a kind of display packing and device of complex crossing.
Background technology
In present urban road layout; Receive the restriction of many-sided factor; Road conditions becomes increasingly complex; Like the range upon range of situation that occurs on overpass and the viaduct, the road conditions of the place of the bridge up and down turning point of overpass and viaduct, and the service road of laying special purpose in the broad road in city; With the complicated road of these situation general designations, can not use simple prompting can specify the crossing of the outlet of any bar road to be referred to as complex crossing in the crossing turning to of occurring on these complicated roads like " left-hand rotation " " right-hand rotation ".
In the prior art, during about the show complex crossing, generally adopt mode chart and virtual graph to come the condition of road surface at show complex crossing in the navigator; But practice finds that mode chart and virtual graph generally are to complete in advance in advance, store in the navigator again; Wherein, accomplish, cause the data acquisition cost of mode chart too high because mode chart is generally taken by manual work; And the manpower of labor, and data volume is bigger; Because virtual graph is to be drawn by simple point-line-surface to form, the elementary path information of reflection complex crossing that can only be rough, and can not reflect the condition of road surface of complex crossing really comprehensively; In addition, the quantity that is stored in mode chart and virtual graph in the navigator also is very limited, can not effectively show complex crossing, can not satisfy navigator user's demand.
In the prior art; Also there is the method for using crossing enlarged map show complex crossing; Promptly in navigation procedure, when complex crossing is shown, utilize the navigation data in the navigator to repaint the condition of road surface that a crossing enlarged map shows current complex crossing; Because repainting the method for crossing enlarged map can only be based on same fixing engineer's scale; Big and be the place of bridge up and down of overpass or viaduct when complicated when the crossing area of drawing, the full detail of drawing out the crossing that can not be whole causes the navigation failure; And all can repaint crossing enlarged map when complex crossing occurring at every turn, with taking the more time of navigator when handling navigation map, reduce the treatment effeciency of navigator, and lacked dirigibility.
Summary of the invention
The embodiment of the invention provides a kind of display packing and device of complex crossing, is used for complex crossing is carried out effectively and demonstration flexibly, improves the treatment effeciency of navigator.
The display packing of a kind of complex crossing that the embodiment of the invention provides comprises:
When having complex crossing in the scope that the current location of distance users presets, judge in navigation map, whether there be the image data corresponding with complex crossing,
If, the image data that the show complex crossing is corresponding;
If not, read complex crossing corresponding map data in navigation map;
Data according to the map are according to the corresponding crossing enlarged map in the engineer's scale drawing complex crossing of presetting;
Show crossing enlarged map.
The display device of a kind of complex crossing that the embodiment of the invention provides comprises:
Judging unit when being used for having complex crossing in the scope that the current location when distance users presets, judges in navigation map, whether there be the image data corresponding with complex crossing,
First display unit is used for when navigation map exists with the corresponding image data of complex crossing the image data of show complex crossing correspondence;
Reading unit is used for when navigation map does not exist with the corresponding image data of complex crossing, reading complex crossing corresponding map data in navigation map;
Drawing unit is used for data according to the map, according to the corresponding crossing enlarged map in the engineer's scale drawing complex crossing of presetting;
Second display unit is used to show crossing enlarged map.
Can find out that from above technical scheme the embodiment of the invention has the following advantages:
In embodiments of the present invention; When having complex crossing in the scope that the current location of distance users presets; The image data that whether the display device judgement exists in navigation map and this complex crossing is corresponding of complex crossing is if can show the image data that this complex crossing is corresponding; If not, can draw the crossing enlarged map of this complex crossing and show this crossing enlarged map.Because the display device of the complex crossing in the embodiment of the invention can at first be judged the image data that whether this complex crossing exists and this complex crossing is corresponding in navigation map; Then; Can adopt different modes to show this complex crossing respectively; Like image data or crossing enlarged map, can realize complex crossing effectively and is flexibly shown, improved the treatment effeciency of navigator.
