Embodiment
In order to make purpose of the present invention, technical scheme and advantage clearer,, the present invention is further elaborated below in conjunction with drawings and Examples.Should be appreciated that specific embodiment described herein only in order to explanation the present invention, and be not used in qualification the present invention.
In embodiments of the present invention, by show the image data of the nearest entrance of dividing the fork in the road in the display screen of navigator, when the user arrived the crossing of situation complexity, the user can judge own residing position accurately and rapidly.
Fig. 1 is the synoptic diagram of the branch fork in the road that provides of the embodiment of the invention, with the crossroad is example, the O point is the central point of this crossroad, the navigational system internal memory contains the latitude and longitude information of this point, the user can reach the O point from four different roads, the central point O point place correspondence of closing on the crossroad at each bar road is provided with inlet point A, a B, C, D point respectively, the latitude and longitude information that corresponding stored A, B, C, D orders in the navigational system, and distinguish corresponding stored from A, B, C, D point real picture or the tri-dimensional picture towards O point direction; Certainly, A, B, C, D point can not have corresponding real picture or tri-dimensional picture yet, perhaps have only some or a plurality of corresponding stored wherein that real picture or tri-dimensional picture are arranged.
Fig. 2 is the flow process of the method that shows of the road that provides of the embodiment of the invention, and details are as follows:
In step S201, according to user's current location and the information in the electronic chart, judge in default distance whether have the branch fork in the road, if execution in step S202 then, otherwise execution in step S203.
As one embodiment of the present of invention, after the navigation beginning, navigational system judges in the default distance whether have the branch fork in the road according to user's current location and the information in the electronic chart, if execution in step S202 then, otherwise execution in step S203.
In step S202, judge the image data of each inlet point that whether stores corresponding described minute fork in the road in the navigational system, if having then execution in step S204, otherwise execution in step S203.
In embodiments of the present invention, image data is real picture or tri-dimensional picture.
In step S203, show the plane electronics map of current position.
In step S204, each inlet point of more described minute fork in the road and the distance between the current location are obtained and user's the current location inlet point apart from minimum.
In step S205, judge whether store the image data corresponding in the navigational system with described inlet point, if execution in step S206 then, otherwise execution in step S203.
In step S206, read the image data corresponding with described inlet point.
In step S207, show the image data corresponding with described inlet point.
The specific implementation process is consulted Fig. 1, the E point is user's a current location, navigational system is at first judged and is drawn apart from the E point predeterminable range a minute fork in the road being arranged, judge each inlet point A of described minute fork in the road again, B, C, whether the D point has real picture or tri-dimensional picture, if real picture or tri-dimensional picture are arranged, then compare the E point to A, B, C, distance between the D point, it is minimum to the distance between the current location E point to calculate the D point, navigational system begins to judge whether store the real picture or the tri-dimensional picture of ordering corresponding to D in the navigational system, if have then described real picture or tri-dimensional picture are presented on the display screen of guider, present to the user.
Be example only in the present embodiment, obviously have only three inlet ports, or greater than four inlet ports, technical scheme of the present invention stand good when the branch fork in the road with the branch fork in the road that four inlet ports are arranged.
One of ordinary skill in the art will appreciate that, realize that all or part of step in the foregoing description method is to instruct relevant hardware to finish by program, described program can be in being stored in a computer read/write memory medium, described storage medium is as ROM/RAM, disk, CD etc.
Fig. 3 is the structural representation of the navigator that provides of the embodiment of the invention, for convenience of explanation, only shows the relevant part of the embodiment of the invention.Wherein the road device shown is software unit or the hardware cell that is built in the navigator.Wherein, road device shown 31 comprises branch fork in the road judging unit 311, image data judging unit 312, minor increment inlet point acquiring unit 313, minor increment inlet point image data judging unit 314, image data acquiring unit 315, image data display unit 316.
Divide fork in the road judging unit 311 according to user's current location and the information in the electronic chart, whether judgement exists the branch fork in the road in default distance, if exist, then judge the real picture or the tri-dimensional picture of each inlet point that whether stores corresponding described minute fork in the road in the navigational system by image data judging unit 312, if have then obtain and user's current location inlet point, otherwise show the plane electronics map of current position apart from minimum by described minor increment inlet point acquiring unit 313.
When fork in the road judging unit 311 judged that existence divided the fork in the road in described minute, each inlet point of 313 more described minutes forks in the road of minor increment inlet point acquiring unit and the distance between the current location, obtain and user's current location inlet point apart from minimum, minor increment inlet point image data judging unit 314 judges whether store real picture corresponding with described inlet point or tri-dimensional picture in the navigational system, if exist, then read the real picture or the tri-dimensional picture of described inlet point correspondence, show the real picture or the tri-dimensional picture of described inlet point correspondence by image data display unit 316 by image data acquiring unit 315.Concrete condition does not repeat them here as mentioned above.
In embodiments of the present invention, by in the display screen of navigator, showing the image data of the nearest entrance of dividing the fork in the road, when the user arrived the crossing of situation complexity, the user can judge own residing position accurately and rapidly, and the user is easy to use, practical.
The above only is preferred embodiment of the present invention, not in order to restriction the present invention, all any modifications of being done within the spirit and principles in the present invention, is equal to and replaces and improvement etc., all should be included within protection scope of the present invention.
