Installation is equipped with positioning device, for obtaining the geographical location information of the first vehicle 410 and the second vehicle 420 respectively, for example, should
Positioning device is GPS (Global Positioning System, global positioning system) module, passes through the real-time of positioning device
Positioning refers to Fig. 2 and Fig. 3, and the first vehicle 410 and the second vehicle 420 get respective position in real time respectively, generates the first vehicle
410 first location information and the second location information of the second vehicle 420, the first vehicle 410 and the second vehicle 420 lead to respectively
It crosses network and first location information and second location information is sent to server 430, so that server 430 can obtain in real time
Take the geographical location of the first vehicle 410 and the second vehicle 420.For example, the first vehicle 410 and the second vehicle 420 pass through nothing respectively
Gauze network is connect with server 430, which can be one of 3G, 4G or a variety of.
Step S160 is generated and the first mesh according to the variation that the first location information and the second location information occur
Mark the first track corresponding with the second target and the second track.
In the present embodiment, since vehicle is to be in traveling shape body, the first of the first vehicle 410 and the second vehicle 420
Location information and second location information will constantly change, and server 430 is according to the first vehicle 410 of record and the second vehicle
420 first location information and the change information of second location information, corresponding first track of generation and the second track, i.e., first
Track is the driving trace of the first vehicle 410, and the second track is the driving trace of the second vehicle 420.
Step S180 will be described when second track is overlapped in current preset time period with first track
Road conditions video is sent to the second target.
In the present embodiment, when second track is overlapped in current preset time period with first track, then when
Preceding first vehicle 410 is identical with 420 driving direction of the second vehicle, alternatively, current first vehicle 410 and the second vehicle 420 traveling
Path is identical, and specifically, preset time period is the first vehicle 410 and the second vehicle 420 in the early time sometime to current
The period of time, the second track and the first track are overlapped in this period, show the first vehicle 410 and the second vehicle 420
Within a period of time before this, driving path is identical, in this way, the road conditions video of the first vehicle 410 is then for the second vehicle 420
Saying has sizable reference significance, and therefore, the road conditions video of the first vehicle 410 is sent to the second target by server 430, is made
The road conditions video with its vehicle with identical driving path can clearly be obtained by obtaining the second vehicle 420, it is worth mentioning at this point that,

Step S182 is then associated with when second track is overlapped in current preset time period with first track
The first object and second target.
In the present embodiment, the vehicle travelled on road is more, and the road conditions video obtained is also more, in order to enable
The road conditions video that second vehicle 420 obtains has reference value as much as possible, needs for different vehicles to be associated, distinguish,
For example, association refers to that the virtual link for establishing the first vehicle 410 and the second vehicle 420 is for another example divided multiple vehicles
Group, the vehicle in same grouping is associated, and for another example, relating value must be that the first vehicle 410 enters the optional of the second vehicle 420
List.When the first vehicle 410 and the second vehicle 420 are overlapped in current preset time period, then the first vehicle 410 and are associated with
Two vehicles 420 are then associated with this two cars, in some implementations that is, when two cars driving path having the same whithin a period of time
In example, when there are more vehicles form path having the same whithin a period of time, being then associated with this more vehicles.
The road conditions video of the associated first object is sent to second target by step S184.
In the present embodiment, associated vehicle is specifically currently to have and mutually go together with identical driving path
The vehicle in path is sailed, the road conditions video of the first vehicle 410 is sent to the second vehicle 420 by server 430.
In one of the embodiments, as shown in Fig. 2, step S184 is specifically included:
Step S184a obtains the video identifier of the road conditions video.
The video identifier of the associated first object is sent to second target by step S184b.
In the present embodiment, since associated vehicle is more, for example, the second vehicle 420 is closed with multiple first vehicles 410
Connection, i.e., a certain vehicle and multiple vehicles driving path having the same, and such as send out the road conditions video of multiple first vehicles 410
It send to the second vehicle 420, on the one hand the network usage of the second vehicle 420 will be caused higher, it is possible to cause the second vehicle 420
Network congestion, be unfavorable for the reception of the road conditions video of the second vehicle 420, on the other hand, increase the load of server 430,
Cause video forward efficiency low.Therefore, in the present embodiment, after server 430 obtains road conditions video, or road conditions video is obtained
When, the corresponding video identifier of road conditions video is obtained, which distinguishes the road conditions video for identification, for example, the video
The mark of corresponding first vehicle 410 is identified, for example, video identifier is the character string of the license plate number comprising the first vehicle 410
Information, for example, video identifier is the license plate number of the first vehicle 410.
One embodiment is the video identifier for obtaining the road conditions video, will be described in the associated first object
Video identifier is sent to second target, sends the corresponding road of the video identifier according to the play instruction that the second target is sent
Condition video is to second target, in this way, server 430 is corresponding by the road conditions video for getting multiple first vehicles 410
Video identifier, and video identifier is sent to the second vehicle 420, multiple first vehicles are shown with tabular form on the second vehicle 420
Play instruction is fed back to service after getting the play instruction of driver on the second vehicle 420 by 410 video identifier
Corresponding road conditions video is sent to the second vehicle 420 and plays out display, avoids sending simultaneously more by device 430,430 ability of server
A road conditions video and the case where cause network congestion, effectively reduce network congestion, and reduce the load of server 430.
In one of the embodiments, as shown in Fig. 2, after step S140 further include:
Step S152 calculates the path distance between the first location information and the second location information.
Specifically, the path distance in this step is the distance calculated according to road in system of geographic location, geographical position
The system of setting is the map for being provided with location information, and location information is the information of the confirmation unique positions of longitude and dimension combination, the
One location information and second location information respectively correspond two positions in system of geographic location, and between the two positions away from
From can be linear distance, it is also possible to the distance that road is calculated according to the map, it should be understood that though linear distance
It is so shortest distance, but due to having barrier between the straight line line of the two, for example, lake, building or meadow etc., and
In reality vehicle can not be directed across barrier traveling, and path distance be along map can travel road be calculated away from
From, therefore, the path distance between the first vehicle 410 and the second vehicle 420 be on the first vehicle 410 and the second vehicle 420
It can travel the shortest distance on road, make the traveling between the first vehicle 410 and the second vehicle 420 by calculating path distance
Relevance is higher.
Step S154, when the path distance between the first location information and the second location information is pre- less than first
It is if distance threshold, then the corresponding first object of the first location information and the second location information is corresponding described
Second target association.
In the present embodiment, when the path distance between the first vehicle 410 and the second vehicle 420 is less than the first pre-determined distance threshold
When value, then the first vehicle 410 is associated with the second vehicle 420, it should be understood that due to the vehicle with identical driving trace
Quantity is possible to very more, therefore, if the biggish vehicle of two path distances is associated with, the reference of the road conditions video obtained
It has little significance, in order to improve relevance, so that the transmission accuracy of road conditions video is higher, it is in the present embodiment, path distance is small
It is associated in two vehicles of the first pre-determined distance threshold value, in this way, since the distance between two vehicles are relatively close, the second vehicle
The path video of 420 the first vehicles 410 obtained has more reference value, and relevance is higher.
In one of the embodiments, when the path distance between the first location information and the second location information
Greater than the second pre-determined distance threshold value, then cancel the corresponding first object of the first location information and the second confidence
Cease the association of corresponding second target.
Specifically, in order to reduce the load of server 430, and the relevance between two vehicles is improved, in 410 He of the first vehicle
The path distance of second vehicle 420 is greater than the second pre-determined distance threshold value, then cancels the pass of the first vehicle 410 and the second vehicle 420
On the one hand connection can be reduced optional first on the second vehicle 420 after the association for cancelling the first vehicle 410 and the second vehicle 420
The quantity of vehicle 410 reduces data transmission, reduces the load of server 430, and, when the first vehicle 410 and the second vehicle 420
Between path distance it is larger when, the relevance between two vehicles is also relatively low, therefore, cancels the association between two vehicles, has
The road conditions video obtained conducive to the second vehicle 420 has more reference value.
It is noted that the second pre-determined distance threshold value is equal to the first pre-determined distance threshold value in one embodiment, and another
In outer one embodiment, the second pre-determined distance threshold value is greater than the first pre-determined distance threshold value, the first vehicle 410 and the second vehicle 420
Path distance in the first pre-determined distance threshold range, the degree of association between the two is higher, the second vehicle 420 obtain association
The road conditions video of the first vehicle 410 have more reference value, and when path distance is greater than the first pre-determined distance threshold value, not directly
The association to disappear between the two is picked up, but when path distance is greater than the second pre-determined distance threshold value, cancel association between the two.
It should be understood that in the process of moving, due to road conditions difference and to travel behavior different, would potentially result in the in this way
The path distance of one vehicle 410 and the second vehicle 420 changes, such as the path between the first vehicle 410 and the second vehicle 420
Distance cancels association between the two after being greater than the first pre-determined distance threshold value, and between the first vehicle 410 and the second vehicle 420
Path distance less than after the first pre-determined distance threshold value be associated with both, then will lead to the frequency of the first vehicle 410 and the second vehicle 420
It is numerous association or frequently cancel association, not can avoid the influence of speed and road conditions to path distance, therefore, the present embodiment pass through by
Second pre-determined distance threshold value is set greater than the first pre-determined distance threshold value, can effectively avoid above-mentioned influence, and can effectively avoid by
Frequently be associated with or frequently cancel and being associated with for the first vehicle 410 and the second vehicle 420 is caused in speed and the variation of road conditions, into one
Step reduces the load of server 430.
In one of the embodiments, in step S180 specifically:
When second track is overlapped in current preset time period with first track, and the current second position
Information is located in the first track, and when current first location information is not located in the second track, the road conditions video is sent to
