Specifically, step 205 includes：
Step 2051, video sampling unit are converted to each frame in the corresponding all frames of active position information corresponding
Image.
The corresponding image of each frame is combined into significance bit confidence in the current setting period by step 2052, video sampling unit
Cease corresponding still image set.
Step 206, video sampling unit deposit the corresponding still image set of active position information in the current setting period
It stores up to corresponding storage root in database.
In the database, each active position information of the position range for the cell that base station is covered corresponds to a data
Store path URL, each store path URL in library correspond to a storage root, and each root that stores corresponds to one
Update (UPDATE) index.In other words, each active position information corresponds to a more New Set.
Specifically, in this step, video sampling unit active position information in generating the current setting period is corresponding
After still image set, the corresponding still image set of active position information in the current setting period can be stored to database
In corresponding storage root.Under the storage root, the active position information that is stored in the current setting period and its right
The still image set answered.
Specifically, if being stored under the corresponding storage root of active position information in database in a setting period has
When imitating the corresponding still image set of location information, then significance bit in the upper setting period stored under the storage root was deleted
Confidence ceases corresponding still image set, and will currently set the corresponding still image set storage of active position information in the period
To the storage root.In other words, the setting period is the corresponding static map image set of active position information that database is stored
The update cycle of conjunction, within the currently setting period, if the corresponding storage root of active position information has new static map image set
When arrival, then the corresponding static map image set of active position information in the upper setting period stored under the storage root was deleted
It closes, and the corresponding still image set of active position information in the current setting period is stored to the storage root.
In the present embodiment, the active position information in the real time information of the car-mounted terminal in the acquired current setting period
All active position information of the position range for the cell that base station is covered might not be covered.In other words, in current setting week
In phase, it is understood that there may be partially significant bit confidence, which ceases corresponding position, does not have vehicle to pass through situation, then for the partially significant bit
Confidence ceases, within the currently setting period, in the database, under the corresponding storage root of partially significant bit confidence breath, according to
The partially significant bit confidence being so stored in a setting period ceases corresponding still image set.In the present embodiment, working as
In the preceding setting period, retains the partially significant bit confidence and cease the static state stored in corresponding storage root in a upper setting period
Image collection.In the case, it should be appreciated that partially significant bit confidence breath is the position for the cell that base station is covered
In all active position information of range, except when effective in the real time information of acquired car-mounted terminal in the preceding setting period

At this point, within the currently setting period, there is not vehicle to pass through feelings if ceasing corresponding position there are partially significant bit confidence
When condition, then within the currently setting period, in the database, it is stored with having for the car-mounted terminal acquired in current set in the period
Remaining active position information institute of the position range for the cell that the corresponding static map image set of effect location information and base station are covered
Still image set in a corresponding upper setting period.
It is stored under the corresponding storage root of active position information in step 207, video sampling unit judges database
Whether still image set is the corresponding still image set of active position information in the current setting period, if so, effectively by this
More New Set corresponding to the corresponding storage root of location information is set as the first setting value, if it is not, by the active position information
More New Set corresponding to corresponding storage root is set as the second setting value.
In this step, if video sampling unit judges go out under the corresponding storage root of active position information in database
The still image collection of storage is combined into the corresponding still image set of active position information in the current setting period, shows the significance bit
Confidence ceases the still image set stored under corresponding storage root and has been updated to newest still image set, therefore, needs
The more New Set corresponding to the corresponding storage root of the active position information is updated, active position information is corresponding deposits by this
More New Set corresponding to storage root is set as the first setting value, for example, first setting value is 1.
If video sampling unit judges go out the static state stored under the corresponding storage root of active position information in database
Image collection is not the corresponding still image set of active position information in the current setting period, shows the active position information pair
The still image set stored under the storage root answered is not updated, under the storage root, is still store one and is set
Still image set in fixed cycle, therefore be also required to update corresponding to the corresponding storage root of the active position information more
More New Set corresponding to the corresponding storage root of the active position information is set as the second setting value, for example, should by New Set
Second setting value is 0.
The corresponding still image set of active position information is stored in database within by all current setting periods, and updates
After corresponding more New Set, it is also necessary to the corresponding sample image collection table (SAMPLE_TABLE) in library is updated the data, in sample graph
As the field recorded in collection table includes effective location information and the storage root of corresponding renewal time, still image set
URL and UPDATE indexs etc..
It is right that step 208, video sampling unit will currently set the corresponding storage root institute of active position information in the period
The more New Set answered is exported to 3D rendering synthesis unit.
Step 209,3D rendering synthesis unit judge more New Set as the first setting value or the second setting value, if first
Setting value executes step 210, if the second setting value, executes step 214.
Wherein, the first setting value is 1, and the second setting value is 0.When first setting value is 1, show in the currently setting period
Interior, what is stored under the corresponding storage root of the active position information is that active position information is corresponding quiet in the current setting period
State image collection shows currently to have set the corresponding still image set stored under root of active position information in the period
It is updated；When second setting value is 0, show within the currently setting period, under the corresponding storage root of the active position information
Storage was the corresponding still image set of active position information in a upper setting period, i.e., within the currently setting period, this has
The still image set stored under the corresponding storage root of effect location information is not updated.
Step 210,3D rendering synthesis unit obtain the corresponding static map image set of active position information in the current setting period
It closes.
When the value for judging the corresponding more New Set of the corresponding storage root of active position information in the currently setting period
For the first setting value when, show within the currently setting period, what is stored under the corresponding storage root of the active position information is
The corresponding still image set of active position information in the current setting period, that is, show currently to set active position information in the period
Still image set under corresponding storage root has been updated, therefore executes step 210, to obtain in the current setting period
The corresponding still image set of the active position information.
Specifically, 3D rendering synthesis unit is corresponding quiet from active position information in the current setting period is obtained in database
