Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is clearly and completely described, obviously, described embodiment is only the present invention's part embodiment, rather than whole embodiment.Based on the embodiment in the present invention, those of ordinary skills belong to the scope of protection of the invention not making the every other embodiment that obtains under the creative work prerequisite.
The embodiment of the present invention provides a kind of method of adjusting the navigation map engineer's scale, comprising: obtain the guider current location, and obtain described guider apart from the traffic information of destination; According to the described traffic information that obtains, the routing point that the navigation map of described guider need show is set, described routing point comprises any one or more in corner point, track, traffic lights, one-way road, restricted driving road, crowded road, traffic control road; According to the routing point of described setting and the engineer's scale of the navigation map on the described guider of vehicle current location, so that described navigation map shows that with suitable ratio described guider is to the traffic information between described routing point.The method of the adjustment navigation map engineer's scale that the embodiment of the present invention provides according to the automatic resize ratio chi of routing point of setting, can be adjusted the navigation map of guider automatically according to user's needs, avoids the manually operated ineffective activity of user.
Below in conjunction with Fig. 1-Fig. 2, the specific embodiment of the method for adjustment navigation map engineer's scale of the present invention is described.
Fig. 1 is the schematic flow sheet of an embodiment of the method for adjustment navigation map engineer's scale of the present invention.As shown in Figure 1, the method for the present embodiment comprises:
Step S110 obtains the guider current location, and obtains described guider apart from the traffic information of destination.
In specific implementation; when opening guider; guider can show a navigation map with a fixed proportion chi usually; and the current current location on map of guider is shown; after the user selected your destination on described navigation map, guider will provide one by the routing information (such as with complete trails show the path of current location and destination) of current location to the destination for the user.Step S110 do normally in the situation that the user selected your destination and to have carried out.Concrete, described guider can comprise that apart from the traffic information of destination the lower n(n of distance is more than or equal to 1) distance of individual corner point, arrive lower n(n more than or equal to 1) whether traffic lights are arranged in the distance at individual crossing, path, whether number of track-lines, the track of the road that travels are that one-way road, lower n(n are more than or equal to 1) whether individual crossing have driving restriction, road congested conditions, whether traffic control etc. information arranged.
Step S112 arranges according to the described traffic information that obtains the routing point that the navigation map of described guider need show.
In specific implementation, described routing point comprises any in corner point, track, traffic lights, one-way road, restricted driving road, crowded road, traffic control road.Such as, among the path of destination, corner point is arranged when getting the guider current location at step S110, therefore, at step S112, the nearest corner point of distance navigation device can be set is the routing point.For another example, when get the guider current location at step S110, the highway section of traffic control is arranged among the path of destination, and it is just in the not far part of guider, therefore, the highway section that described traffic control can be set at step S112 is the routing point.
In specific implementation, step S112 can regularly carry out according to the default time cycle.
Step S114 obtains the latitude and longitude information of the latitude and longitude information of described guider current location, described routing point and the dimension information of guider display screen.
In specific implementation, the demonstration of the selected element on navigation map can realize in the following way, at first obtain the latitude and longitude coordinates of described selected element, then convert described latitude and longitude coordinates to screen coordinate, at last described screen coordinate is shown on described navigation map.
Step S116 adjusts the engineer's scale of navigation map on described guider, so that described navigation map is presented at described guider in the range of size of described display screen to the traffic information between described routing point with the ratio of maximum.
In specific implementation, can get via satellite the latitude and longitude information of longitude and latitude and the routing point of guider current location, and the size of guider display screen is normally fixed, the engineer's scale that the information of obtaining by step S114 at step S116 is like this adjusted navigation map automatically gets final product.Such as, during adjustment, the guider current location can be corresponded to the lower left corner of display screen, the routing point corresponds to the upper right corner of display screen, but thus maximum ratio ground display navigation apparatus current location to the traffic information of routing point.For another example, during adjustment, the guider current location can be corresponded to the centre of display screen, the routing point corresponds to the upper right corner of display screen, thus can be in the scope of determining with the traffic information of maximum ratio ground display navigation apparatus current location to routing point.
Fig. 2 is another embodiment schematic flow sheet of the method for adjustment navigation map engineer's scale of the present invention.The method of the present embodiment comprises as shown in Figure 2:

Step S214 is for described multiple routing point Set scale chi is adjusted priority level and weighting coefficient information.
Step S216, automatically adjust the engineer's scale of navigation map on described guider according to priority level and the weighting coefficient of the routing point of setting according to priority mode from high to low, so that described navigation map shows that with suitable ratio described guider is to the traffic information between described routing point.
In specific implementation, adjust the engineer's scale of navigation map at the routing point that step S216 can be at first the highest according to priority, so that described navigation map shows that with maximum ratio described guider is to the traffic information of the highest routing point of described priority.On this basis, the weighting coefficient of the routing point time high according to priority and described selected element carries out part adjustment to the engineer's scale of above-mentioned maximum ratio chi again so that described navigation map with the described inferior high routing point of the engineer's scale demonstration that meets described weighting coefficient to the traffic information between guider.How according to the mode of the resize ratio chi of the routing point of follow-up priority, the mode that can take with reference to above-mentioned high routing point is not given unnecessary details at this.
Step S218 when described guider is crossed described routing point, returns to the navigation map of described guider the engineer's scale state of the nearest preservation before adjusting.
Execution in step S218 can facilitate guider to carry out fast the adjustment of engineer's scale according to user's different choice in real time.
Accordingly, the embodiment of the present invention also provides a kind of guider, and this guider can be placed on the vehicles such as automobile, carries out automobile navigation, also can be placed on the mobile terminal such as mobile phone, carries out the navigation of user's track route.
