Embodiment
To make the object, technical solutions and advantages of the present invention clearer, below in conjunction with implementation of the accompanying drawing to the present invention
Example is described in detail.
Fig. 1 is the flow chart according to the map loading method for being used to navigate of the offer of the present invention.
According to Fig. 1, the map loading method for being used to navigate includes：
In step S101, with animation mode real-time display navigation map.
On the animation shown in map, Fig. 2 is referred to, Fig. 2 shows navigation according to an embodiment of the invention
The schematic diagram of animation.Such as Fig. 2, one is shown from " Zhong Guan-cun " to the self-driving navigation way of " Xizhimen subway station ", the route
Near show Dan Lengjie, Haidian South Road, Shuangyushu North Road etc..In navigation procedure, animation shows as the amplification of map scale
Or diminution, the change in direction or/and the conversion at visual angle, the visual angle include depression angle, side view angle etc..Please continue to refer to Fig. 3, figure
3 show the static schematic diagram for the navigation animation for occurring turning round on navigation circuit according to an embodiment of the invention.Such as figure
3, the navigation animation when complex road condition such as occurring turning round on navigation circuit is shown, the navigation animation includes traffic lights, electricity
Some traffic signs such as sub- eye and 3D streetscape figures.Shown according to one embodiment of present invention please continue to refer to Fig. 4, Fig. 4
Navigation map on occur complicated highway section navigation animation schematic diagram.Such as Fig. 4, show occur crossroad on navigation map
Or during the complicated highway section such as viaduct, navigation map can be transitioned into depression angle animation from former view angle switch, while reduce map
Ratio is so that user can comprehensively check the situation and trend of complicated highway section.
In step s 102, based on not shown around the pre-loaded current screen show map of current screen show map
Map datum.
In existing airmanship, an animation is often performed, map datum just needs to reload once；To perform animation
24 frames of frequency/just need to load map datum 24 times exemplified by the second, in 1 second, so cause CPU usage more than 70%, consume
Electricity is also bigger.In true navigation procedure, corresponding to the actual travel speed of user in map shown by current screen
For, movement is relatively very slow, it is possible to was all difficult remove whole screen 1/10 in 10 seconds.
The embodiment of the present invention considers above-mentioned characteristic, using not shown around pre-loaded current screen show map
Diagram data, all without the scope for walking out current screen show map in following many frames that animation performs.Due to being held in animation
After capable following many frames, user advance position corresponding in map shown by current screen all without beyond shown
The scope of map, so as in the case of pre-loaded certain map datum, now be avoided the need for again in a very long time
Secondary loading map datum, so as to greatly reduce the number of loading map datum, effectively reduce CPU usage.
Alternatively, the pre-loaded body of a map or chart is the 1/10-1/3 that current screen show map circumferential extent is screen
Not shown map datum.
Alternatively, the pre-loaded body of a map or chart is current screen show map in Present navigation route direction of advance
One or both sides edge outside not shown map datum.
For example, active user is travelling from east to west, pre-loaded body of a map or chart can be from westwards or/and to North and South direction
Load not shown map datum around current screen show map simultaneously.
Alternatively, pre-loaded body of a map or chart is one of current screen show map in Present navigation route direction of advance
Width is the 1/10-1/3 of screen not shown map datum outside side or both sides of the edge.
Alternatively, the pre-loaded body of a map or chart is：According to the speed of Present navigation around current screen show map
Predict the not shown map datum that may be used in the 5-10 seconds.
For example, user's current driving speed gait of march is 60km/h, navigating can predict according to current driving speed
60km/h*5s-60km/h*10s, i.e., the distance range current location 80m- that user may advance in the pre-loaded distance 5-10 seconds
Corresponding map datum in the range of 170m.
Alternatively, pre-loaded body of a map or chart is one of current screen show map in Present navigation route direction of advance
Outside side or both sides of the edge, according to the prediction of speed of Present navigation in the 5-10 seconds in the not shown map number that may use
According to.
Alternatively, based on the pre-loaded map datum and navigation way currently shown, speed and direction prediction future
The animated video data that will be used in the scheduled time, previously generate the animated video data and are cached.Alternatively, the future
The scheduled time is the 5-10 seconds.
Show that user is currently located near " Tian An-men " on map for example, working as, and know that user works as by hind computation
Preceding speed is 0.5 meter per second, and the direction of traveling is from east to west, based on can in these data predictions user's scheduled time in future
Mobile scope includes the regions such as periphery " Xidan " and " Wangfujing ", then pre-loaded body of a map or chart includes periphery " Xidan "
Map datum corresponding to regions such as " Wangfujings ", previously generate animated video corresponding with the region such as " Xidan " and " Wangfujing "
Data are simultaneously cached the animated video data generated.
In step S 103, the animated image subsequently shown using pre-loaded map datum generation is navigated.
For example, on map, when knowing that user sails out of " Tian An-men " arrival " Wangfujing " nearby by hind computation, extraction
In step S 102 animated video data and user is provided it to corresponding to pre-loaded and caching " Wangfujing " region.
Further, know that user marched to " Wangfujing " in 2 minutes from " Tian An-men " by hind computation, it is slow due to advancing,
It is very short relative to the whole map area travel distance of display, then in this 2 minutes, it can directly utilize pre-loaded map
The animated image that data generation is subsequently shown is navigated, without reloading map datum.In this way, can effectively it reduce
CPU utilization rate, lift CPU performance.
In step S 104, if pre-loaded map datum is not enough to generate follow-up animated image, add again
Carry map datum.
For example, on map, when knowing that user reaches " Wangfujing " region by hind computation, and obtain described in step
Pre-loaded map datum is not enough to generate follow-up animated image in rapid S102, then reloads map datum, described heavy
The map datum newly loaded includes the map datum of such as neighboring area such as " Jianguomen ", " Dengshikou ", " Chongwenmen ".This implementation
In example, effectively map datum can be reloaded using the cpu resource discharged in step S102 and step S103.
Embodiments of the invention also disclose a kind of device for the map loading for being used to navigate.Fig. 5 is refer to, Fig. 5 is shown
