Embodiments of the invention provide a kind of air navigation aid, comprising:
When vehicle during the preset distance of nearest crossing, obtains the three-dimensional road data at described crossing apart from the place ahead;
Navigate according to described three-dimensional road data.
The embodiment of the invention also provides a kind of guider, comprising:
Acquiring unit is used for during the preset distance of nearest crossing, obtaining the three-dimensional road data at described crossing apart from the place ahead when vehicle;
Navigation elements is navigated according to described three-dimensional road data.
According to the embodiment of the invention, owing to be equipped with the three-dimensional road data, reflected the actual conditions at crossing exactly at each place, crossing, vehicle is accurately travelled.
Description of drawings
Fig. 1 shows the air navigation aid of the embodiment of the invention one;
Fig. 2 shows the guider of the embodiment of the invention two.
Embodiment
Understand and realization the present invention the existing embodiments of the invention of describing in conjunction with the accompanying drawings for the ease of persons skilled in the art.
Embodiment one
Present embodiment provides a kind of air navigation aid.As shown in Figure 1, comprise the steps:
Wherein said when vehicle apart from the place ahead nearest crossing preset distance, in actual applications, can adopt following steps to judge:
1, determines the current position coordinates of vehicle by GPS (Global Position System, GPS);
2, carry out the road that map match is determined current vehicle place by the current location of vehicle;
3,, determine nearest crossing, the place ahead according to vehicle place road;
4, whether the current location of judging vehicle reaches preset distance apart from the distance at nearest crossing, the place ahead, when nearest crossing, distance the place ahead reaches preset distance, as, when nearest crossing reaches predetermined 1 km apart from the place ahead, obtain the three-dimensional road data at this crossing from the crossing database.
Described three-dimensional road data are used to represent the condition of road surface at variety classes crossing, as kinds such as cruciform crossing, T-shaped crossing, three fork-shaped crossings, five fork-shaped crossings, in order to represent the condition of road surface at these crossings, can form the three-dimensional road data to every type crossing according to the kind at crossing.Described three-dimensional road data comprise entranceway sign, crossing type, crossing three-dimensional model picture data.Form the method for three-dimensional road data: at each crossing type, the road that every crossing is linked to each other is made three-dimensional model picture data respectively as entranceway respectively, and according to every exit road, difference fabrication direction arrow artwork; To put into map of navigation electronic three-dimensional plot valut after three-dimensional model picture data and the direction arrow picture numbering.In the map of navigation electronic data, press the Parking Entrance road, respectively three-dimensional model picture data number is deposited in the database of crossing; Press Parking Entrance road and exit road, direction arrow picture numbering is deposited in the database of crossing.And these three-dimensional road data and its position in electronic chart are mapped, so that vehicle during apart from this crossing specific range, obtains this three-dimensional road data.
The described three-dimensional road data of obtaining from the database of crossing specifically comprise as follows:
1,, obtains crossing three-dimensional model picture data according to current road markings and crossing type;
2, according to current road and exit road, obtain direction arrow.
For example, when vehicle on the way travelled, the GPS on the vehicle can at first determine current position coordinates; Current position coordinates by vehicle carries out the road that map match is determined current vehicle place, i.e. road markings; According to road markings, current location and direct of travel, determine nearest crossing, the place ahead; When the current location of vehicle reaches preset distance apart from the distance at nearest crossing, the place ahead, obtain the three-dimensional road data at this crossing from the crossing database.The three-dimensional road data at this crossing are corresponding with current road and direct of travel.
In other embodiments of the invention, also can obtain direction arrow earlier, obtain crossing three-dimensional model picture data again, perhaps obtain crossing three-dimensional model picture data and direction arrow simultaneously, do not influence realization of the present invention.
Determine that according to path planning next bar travel is an exit road after vehicle is through nearest crossing, the place ahead, determine direction arrow according to current road and exit road, crossing three-dimensional model picture data and direction arrow in the three-dimensional road data that will obtain according to step 11, thus vehicle is travelled toward the Way out of selecting.Also can and show,, be convenient to the driver according to correct route running so that turn-by-turn navigation information clearly to be provided with three-dimensional model picture data and direction arrow stack.Increase driver's satisfaction like this.
Embodiment two
As shown in Figure 2, present embodiment discloses a kind of guider 30.Described guider 30 comprises: acquiring unit 31 is used for during the preset distance of nearest crossing, obtaining the three-dimensional road data at described crossing apart from the place ahead when vehicle; Navigation elements 32 is navigated according to described three-dimensional road data; Form unit 33, be used for before step is obtained the three-dimensional road data, forming the three-dimensional road data, and these three-dimensional road data and its position in electronic chart are mapped; Crossing database 34 is used to store the three-dimensional road data.Described acquiring unit 31 comprises: first determining unit 311 is used for navigating instrument is determined vehicle by GPS current location; Second determining unit 312 is used for determining by map match the road at current vehicle place; The 3rd determining unit 313 is used for during the preset distance of nearest crossing, determining the three-dimensional road data at nearest crossing, the place ahead apart from the place ahead according to vehicle place road when vehicle.The principle of work of above-mentioned each unit can not repeat them here with reference to content among the embodiment one.
According to the embodiment of the invention, owing to be equipped with the three-dimensional road data, reflected the actual conditions at crossing exactly at each place, crossing, vehicle is accurately travelled.
Though described the present invention by embodiment, those of ordinary skills know, without departing from the spirit and substance in the present invention, just can make the present invention that many distortion and variation are arranged, and scope of the present invention is limited to the appended claims.
