Detailed Description
In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the following description will be made with reference to the accompanying drawings. It is obvious that the drawings in the following description are only some examples of the invention, and that for a person skilled in the art, other drawings and embodiments can be derived from them without inventive effort.
[ example 1 ]
As shown in fig. 1, the present invention provides an embodiment of a driving recording method, where the method is executed by a server, and the method includes:
s10: acquiring N original position information points sent by a vehicle at N time nodes; n is a positive integer;
specifically, a vehicle-mounted positioning device can be installed in the vehicle, and a communication device can be installed on the vehicle-mounted positioning device and can report the original position information point of the vehicle to a server according to a certain frequency. For example, the vehicle-mounted positioning device may send the original location information point of the vehicle to the server at a frequency of 60 times per minute, that is, 60 original location information points corresponding to 60 time nodes are uploaded in one minute. The server can receive and acquire 60 original position information points sent by the vehicle at 60 time nodes.
S20: screening the N original position information points according to the position relation among the N original position information points and the time relation among the N original position information points to obtain M effective position information points; m is a positive integer not greater than N;
as described above, the vehicle-mounted positioning device continuously sends the original location information points of the vehicle to the server during the driving process of the vehicle, and if the user wants to obtain the driving track route of the vehicle through the user terminal, sending all the original location information points to the user terminal undoubtedly causes a large data traffic transmission, which is not favorable for the long-term use of the user. Therefore, the present application aims to improve the positioning accuracy, reduce the flow consumption of the user terminal, and clearly reflect the driving state of the vehicle, such as the driving speed and the position, on the generated driving track route.
In the process of simplifying data, the N original position information points are screened according to the position relationship among the N original position information points and the time relationship among the N original position information points. Specifically, the method may include extracting a next original position information point, which is adjacent to the N original position information points and has a distance greater than a preset distance, to form a distance valid position information point, extracting position information points, which have a time interval greater than a preset time interval, from the N original position information points to form a time valid position information point, and then superimposing the position valid information points and the time valid information points to obtain a final valid position information point.
S30: generating a driving track of the vehicle according to the M effective position information points;
specifically, the server may perform punctuation on the map according to the effective position information obtained by the screening, and then generate a driving track of the vehicle.
S40: and when a driving track acquisition instruction sent by the terminal is received, sending the data of the driving track to the terminal.
Specifically, a terminal of a user can establish data communication with a server, the user sends a driving track obtaining instruction to the server through the terminal so as to obtain driving track data from the server, and the server sends the driving track data to the terminal when receiving the driving track obtaining instruction sent by the terminal.
By the driving recording method provided by the embodiment, the original position information point uploaded by the vehicle-mounted positioning device can be further processed, the data transmission quantity of the server and the user terminal is reduced, and the consumption of user traffic is reduced.
[ example 2 ]
As shown in fig. 2, the present invention further provides another embodiment of a driving recording method, which can be executed by a server, and the method includes:
s10: acquiring N original position information points sent by a vehicle at N time nodes, wherein N is a positive integer;
s21: screening the N original position information points according to the position relation among the N original position information points to obtain A distance effective position information points;
the step S21 may include: s211 b: judging whether the distance between the original position information point of the current time node and the original position information point of the last time node is smaller than a preset distance or not;
s212 b: if the current time node is smaller than the preset time node, the original position information point of the current time node is omitted, and the original position information point of the next time node is set as the original position information point of the current time node; returning to step S211b until all the N original location information are filtered;
s213 b: if not, setting the original position information point of the current time node as an effective position information point, and setting the original position information point of the next time node as the original position information point of the current time node; the step S211b is executed again until all the N pieces of original location information are filtered.
Specifically, if the distance between the original location information points of two adjacent time nodes is small, it indicates that the driving speed of the vehicle is slow, and many original location information points with very close relative positions must be generated during the driving process, and if the original location information points are all sent to the user terminal, relatively large data transmission will be generated. Therefore, in this embodiment, it is determined whether the distance between the original location information point of the current time node and the original location information point of the previous time node is smaller than a preset distance; if the distance between the two points is smaller than the preset distance, the original position information point of the current time node can be omitted, and the original position information point of the next time node is set as the original position information point of the current time node; if the distance between the two points is not less than the preset distance, the distance between the two points is larger, the original position information point of the current time node is set as an effective position information point to be reserved, and the original position information point of the next time node is set as the original position information point of the current time node; and then, returning to the next time node for screening processing.
For example: a, B, C, D, E original position information points are collected, the distance between the point A and the point B is 1 meter, the distance between the point B and the point C is 2 meters, the distance between the point C and the point D is 3 meters, the distance between the point D and the point E is 5 meters, the preset distance is set to be 5 meters, the server firstly reserves the initial point, namely the point A, otherwise, the initial position of the automobile cannot be known, then the automobile uses the point B as the original position information point of the current time node, judges whether the distance between the point B and the original position information point (point A) of the previous time node is less than 5 meters, if the judgment result is less than, the point B is discarded, then uses the original position information point (point C) of the next time node as the original position information point of the current time node, and then continuously judges whether the distance between the point C and the original position information point (point A) of the previous time node is less than the preset distance If the distance is 5 meters, and the distance between the point A and the point C is 3 meters or less than the preset distance of 5 meters, the point C is continuously removed, the original position information point (point D) of the next time node is taken as the original position information point of the current time node, then whether the distance between the point D and the original position information point (point A) of the previous time node is less than the preset distance of 5 meters is continuously judged, and if the distance between the point A and the point D is 6 meters and is greater than the preset distance of 5 meters, the point D is kept as the effective position information point, the original position information point (point E) of the next time node is taken as the original position information point of the current time node, the distance is continuously compared with the original position information point D of the previous time node, and similarly, the distance between the point D and the point E exceeds the preset distance of 5 meters, and reserving the E point as an effective position information point. It can be seen that, in the embodiment, the original position information point A, B, C, D, E, F is reduced to A, D, E, and the data volume of the automobile driving track is reduced while the driving track of the automobile is accurately recorded.
S22: screening the N original position information points according to the time relationship among the N original position information points to obtain B time effective position information points;
the step S22 may include:
s221 a: judging whether the time difference between the original position information point of the current time node and the original position information point of the previous time node is less than the preset time or not;
s222 a: if the current time node is smaller than the current time node, the original position information point of the current time node is omitted, the original position information point of the next time node is set as the original position information point of the current time node, and the step S221a is returned to be executed until all the N original position information are screened;
s223 a: if not, setting the original position information point of the current time node as an effective position information point, and setting the original position information point of the next time node as the original position information point of the current time node; the process returns to step S221a until all the N pieces of original location information are subjected to the filtering process.
Specifically, the vehicle-mounted positioning device uploads the original position information points to the server according to a certain frequency, the server can perform further screening after receiving the original position information points, as described above, it can be determined whether the time difference between the original position information points of the two time nodes is less than the preset time, the original position information points with the time difference greater than or equal to the preset time are reserved as valid position information points, and the original position information points with the time difference less than the preset time are discarded.
For example: a, B, C, D, E original position information points are collected, the time node of the point A is the 0 th S, the time node of the point B is the 1 st S, the time node of the point C is the 3 rd S, the time node of the point D is the 7 th S, and the preset time is set to be 3S. The server firstly reserves the initial point, namely the point A, otherwise the initial position of the automobile cannot be known, then the automobile takes the point B as the original position information point of the current time node, judges whether the time difference between the point B and the original position information point (the point A) of the previous time node is less than the preset time for 3 seconds, if the judgment result is that the time difference between the point A and the point B is 1 second and less than the preset time for 3 seconds, the point B is discarded, then the original position information point (the point C) of the next time node is taken as the original position information point of the current time node, then continuously judges whether the time difference between the point C and the original position information point (the point A) of the previous time node is less than the preset time for 3 seconds, if the time difference between the point A and the point C is 3 seconds and not less than the preset time for 3 seconds, the point C is reserved as the effective position information point, setting an original position information point (D point) of a next time node as an original position information point of a current time node, continuously judging whether the time difference between the D point and an original position information point (C point) of a previous time node is less than the preset time for 3 seconds, if so, the time difference between the C point and the D point is 2S, if so, the D point is omitted, setting an original position information point (E point) of the next time node as an original position information point of the current time node, and continuously judging whether the time difference between the E point and the original position information point (C point) of the previous time node is more than the preset time for 3 seconds, if so, the time difference between the C point and the E point is 4 seconds and is more than the preset time for 3 seconds, and then, continuously keeping the E point as an effective position information point. It can be seen that, in the embodiment, the original position information point A, B, C, D, E, F is reduced to A, C, E, and the data volume of the automobile driving track is reduced while the driving track of the automobile is accurately recorded.
It should be noted that the order of S21 and S22 may be reversed.
S23: and integrating the A distance effective position information points and the B time effective position information points to obtain M effective position information points, wherein A, B is a positive integer.
Specifically, as described above, A, D, E three effective position information points are obtained in step S21, and A, C, E three effective position information points are obtained in step S22, so that two processing results can be superimposed to obtain A, C, D, E four effective position information points.
S30: generating a driving track of the vehicle according to the M effective position information points;
and S40, when receiving the driving track acquisition instruction sent by the terminal, sending the driving track data to the terminal.
Specifically, a terminal of a user can establish data communication with the server, the user sends a driving track obtaining instruction to the server through the terminal so as to obtain driving track data from the server, and the server sends the driving track data to the terminal when receiving the driving track obtaining instruction sent by the terminal.
By the driving recording method provided by the embodiment, the original position information points uploaded by the vehicle-mounted positioning device can be further processed, for example, the original position information points close to the time nodes or the original position information points close to the positions are deleted, so that the data transmission amount between the server and the user terminal is reduced, the consumption of user traffic is reduced, and meanwhile, the user can intuitively see the driving condition of the vehicle from the generated driving track.
[ example 3 ]
As shown in fig. 4, the present invention further provides another embodiment of a driving recording method, where the method steps may be executed by a server, and the method includes:
s10: acquiring N original position information points sent by a vehicle at N time nodes, wherein N is a positive integer;
s211 a: judging whether an angle between a driving direction corresponding to the original position information point of the current time node and a driving direction corresponding to the original position information point of the last time node is smaller than a preset angle or not;
s212 a: if the current time node is smaller than the preset time node, the original position information point of the current time node is omitted, and the original position information point of the next time node is set as the original position information point of the current time node; returning to step S211a until all the N original location information are filtered;
s213 a: if not, the original location information point of the current time node is set as the valid location information point, the original location information point of the next time node is set as the original location information point of the current time node, and the step S211a is executed again until all the N original location information are filtered.
During the driving process of the automobile, the automobile has two operation modes of steering and straight driving, and during the driving process of the automobile, the vehicle-mounted positioning device in the automobile can always send the original position information point of the automobile to the server. When the user acquires the vehicle driving track, if the server sends all the original position information points to the user terminal, data transmission is inevitably overlarge, and therefore, in order to reduce the data volume transmitted to the user terminal by the server, the original position data is processed in the embodiment. After the server acquires the N original position information points, the server processes the data according to the uploading time of the original position information points.
When the processing is performed, the original position information point being processed can be recorded as the original position information point of the current time node, and whether the angle between the driving direction corresponding to the original position information point of the current time node and the driving direction corresponding to the original position information point of the previous time node is smaller than a preset angle or not is judged. For example, the preset angle can be set to 5 degrees; if the current time node is greater than the previous time node, the current time node is changed in direction relative to the previous time node, or a turn is made, or a lane change is made; if the current time node is smaller than the previous time node, the direction of the current time node is almost unchanged relative to the previous time node, and the automobile can be considered to be running in a straight line. When the automobile runs in a straight line, the running track of the automobile can be marked only by recording the start position information point and the end position information point in the straight line running process, the middle position information points can be ignored, and if all the original position information points of the whole straight line running public are reserved, the server inevitably generates very large data when sending the vehicle running track data to the user terminal. Therefore, in this embodiment, when it is determined that the angle between the driving direction corresponding to the original position information point of the previous time node and the driving direction corresponding to the original position information point of the previous time node is smaller than the preset angle, the original position information point of the current time node is discarded, and only when it is determined that the angle between the driving direction corresponding to the original position information point of the previous time node and the driving direction corresponding to the original position information point of the previous time node is greater than or equal to the preset angle, the original position information point of the current time node is retained. Therefore, key points of the automobile in the track changing process are recorded, and middle points of straight driving are abandoned.
For example: as shown in fig. 3, when the automobile runs from west to east and reaches the intersection, the automobile instead runs to south, and during the running process from the point a to the point I, the vehicle-mounted positioning device of the automobile uploads A, B, C, D, E, F, G, H, I original position information points to the server. If the server transmits all the 9 original position information points to the user terminal, then when the user travels a long distance, a relatively large data transmission occurs, which causes a waste of resources. Obviously, in fig. 3, all of a to F are driving straight, F to H are turning, and H to I are driving straight, it is seen that only the five original location information points A, G, H, I need to be recorded to draw the driving route map of the automobile.
When processing, the server records the first original position information point A of the automobile, and then when processing the point B, the point B is set as the original position information point of the current time node. And the server judges whether the angle deviation between the direction of the point B and the direction of the original position information point A of the previous time node exceeds a preset angle, if the judgment result is less than the preset angle, the point B is abandoned, then the point C is continuously set as the original position information point of the current time node, and the direction of the point A is continuously compared with the direction of the original position information point A of the previous time node. When the server sets the point G as the current position time node, it can be found that the driving direction of the point G and the point a has changed significantly, so that the point G is reserved as an effective position information point, and similarly, the driving directions of the point G and the point H are also changed, and the point H is reserved.
When the driving direction of the automobile at a certain original position information point is detected, the directions of the original position information point and the original position information point of the previous time node can be calculated, so that the driving direction of the automobile corresponding to the original position information point is obtained. For example, when the driving direction of the vehicle corresponding to the point D is determined, the position direction of the point C and the point D is determined, and it can be seen that the vehicle is driven from west to east from the point C to the point D.
S22: screening the N original position information points according to the time relationship among the N original position information points to obtain B time effective position information points; the implementation of this step can refer to example 2, and is not described herein again.
S23: integrating the A distance effective position information points and the B time effective position information points to obtain M effective position information points; wherein A, B is a positive integer. The implementation of this step can refer to example 2, and is not described herein again.
S30: generating a driving track of the vehicle according to the obtained M effective position information points;
s40: and when a driving track acquisition instruction sent by the terminal is received, sending the data of the driving track to the terminal.
Specifically, a terminal of a user can establish data communication with a server, the user sends a driving track obtaining instruction to the server through the terminal so as to obtain driving track data from the server, and the server sends the driving track data to the terminal when receiving the driving track obtaining instruction sent by the terminal.
By the driving recording method provided by the embodiment, the original position information point uploaded by the vehicle-mounted positioning device can be further processed, the data transmission quantity between the server and the user terminal is reduced, and the consumption of user flow is reduced.
[ example 4 ]
As shown in fig. 5, the present invention further provides another embodiment of a driving recording method, where the method steps may be executed by a server, and the method includes:
s10: acquiring N original position information points sent by a vehicle at N time nodes; n is a positive integer;
specifically, a vehicle-mounted positioning device can be installed in the vehicle, and a communication device can be installed on the vehicle-mounted positioning device and can report the original position information point of the vehicle to a server according to a certain frequency. For example, the vehicle-mounted positioning device may send the original location information point of the vehicle to the server at a frequency of 60 times per minute, that is, 60 original location information points corresponding to 60 time nodes are uploaded in one minute. The server side can receive and acquire 60 original position information points sent by the vehicle at 60 time nodes.
S211 b: and judging whether the distance between the original position information point of the current time node and the original position information point of the previous time node is smaller than a preset distance.
S212 b: if the current time node is smaller than the preset time node, the original position information point of the current time node is omitted, and the original position information point of the next time node is set as the original position information point of the current time node; returning to execute the step S211b until all the N original location information are filtered;
s213 b: if not, the original location information point of the current time node is set as the valid location information point, the original location information point of the next time node is set as the original location information point of the current time node, and the step S211b is executed again until all the N original location information are filtered.
Specifically, in steps S211b-S213b, if the distance between the original location information points of two adjacent time nodes is small, it indicates that the driving speed of the vehicle is relatively slow, and many original location information points having relatively close positions must be generated during driving, and if all of the original location information points are transmitted to the user terminal, relatively large data transmission is generated. Therefore, in this embodiment, it is determined whether the distance between the original location information point of the current time node and the original location information point of the previous time node is smaller than a preset distance; if the distance between the two points is smaller than the preset distance, the original position information point of the current time node can be omitted, and the original position information point of the next time node is set as the original position information point of the current time node; if the distance between the two points is not less than the preset distance, the distance between the two points is larger, the original position information point of the current time node is set as an effective position information point to be reserved, the original position information point of the next time node is set as the original position information point of the current time node, and then the next time node is continuously returned to be screened.
For example, A, B, C, D, E original location information points are collected, the distance between point a and point B is 1 meter, the distance between point B and point C is 2 meters, the distance between point C and point D is 3 meters, the distance between point D and point E is 5 meters, the preset distance is set to 5 meters, the server first reserves the initial point, that is, point a, but cannot know the starting location of the automobile, then the automobile uses point B as the original location information point of the current time node, determines whether the distance between point B and the original location information point (point a) of the previous time node is less than 5 meters, if the determination result is less than, discards point B, then uses the original location information point (point C) of the next time node as the original location information point of the current time node, and then continues to determine whether the distance between point C and the original location information point (point a) of the previous time node is less than 5 meters If the preset distance is 5 meters, and the distance between the point A and the point C is 3 meters or less than the preset distance by 5 meters, the point C is continuously omitted, the original position information point (point D) of the next time node is taken as the original position information point of the current time node, then whether the distance between the point D and the original position information point (point A) of the previous time node is less than the preset distance by 5 meters is continuously judged, and if the result is that the distance between the point A and the point D is 6 meters and is greater than the preset distance by 5 meters, the point D is taken as an effective position information point to be reserved, the original position information point (point E) of the next time node is taken as the original position information point of the current time node, and the distance is continuously compared with the original position information point C of the previous time node, and similarly, the distance between the point D and the point E also exceeds the preset distance by 5 meters, and reserving the E point as an effective position information point. It can be seen that, in the embodiment, the original position information point A, B, C, D, E, F is reduced to A, D, E, and the data volume of the automobile driving track is reduced while the driving track of the automobile is accurately recorded.
S221 a: judging whether the time difference between the original position information point of the current time node and the original position information point of the previous time node is less than the preset time or not;
s222 a: if the current time node is smaller than the preset time node, the original position information point of the current time node is omitted, and the original position information point of the next time node is set as the original position information point of the current time node; returning to execute the step S221a until all the screening processes of the N pieces of original location information are completed;
s223 a: if not, setting the original position information point of the current time node as an effective position information point, and setting the original position information point of the next time node as the original position information point of the current time node; the process returns to step S221a until all the N pieces of original location information are subjected to the filtering process.
Specifically, in steps S221a-S222a, the vehicle-mounted positioning device uploads the original location information points to the server at a certain frequency, and the server may perform further filtering after receiving the original location information points, as described above, determine whether the time difference between the original location information points of the two time nodes is less than the preset time, retain the original location information points with the time difference greater than or equal to the preset time as valid location information points, and discard the original location information points with the time difference less than the preset time.
For example: a, B, C, D, E original position information points are collected, the time node of A is 0S, the time node of B is 1S, the time node of C is 3S, the time node of D is 7S, and the preset time is set to be 3S. The server firstly reserves the initial point, namely the point A, otherwise the initial position of the automobile cannot be known, then the automobile takes the point B as the original position information point of the current time node, judges whether the time difference between the point B and the original position information point (the point A) of the previous time node is less than the preset time for 3 seconds, if the judgment result is that the time difference between the point A and the point B is 1 second and less than the preset time for 3 seconds, the point B is discarded, then the original position information point (the point C) of the next time node is taken as the original position information point of the current time node, then continuously judges whether the time difference between the point C and the original position information point (the point A) of the previous time node is less than the preset time for 3 seconds, if the time difference between the point A and the point C is 3 seconds and not less than the preset time for 3 seconds, the point C is reserved as the effective position information point, setting an original position information point (D point) of a next time node as an original position information point of a current time node, continuously judging whether the time difference between the D point and an original position information point (C point) of a previous time node is less than the preset time for 3 seconds, if so, the time difference between the C point and the D point is 2S, if so, the D point is omitted, setting an original position information point (E point) of the next time node as an original position information point of the current time node, and continuously judging whether the time difference between the E point and the original position information point (C point) of the previous time node is less than the preset time for 3 seconds, if so, the time difference between the C point and the E point is 4 seconds and is more than the preset time for 3 seconds, and then, taking the E point as an effective position information point to be reserved. It can be seen that, in the embodiment, the original position information point A, B, C, D, E, F is reduced to A, C, E, and the data volume of the automobile driving track is reduced while the driving track of the automobile is accurately recorded.
S23: and integrating the A distance effective position information points and the B time effective position information points to obtain M effective position information points, wherein A, B is a positive integer.
S30: generating a driving track of the vehicle according to the M effective position information points;
s40: and when a driving track acquisition instruction sent by the terminal is received, sending the data of the driving track to the terminal.
Specifically, a terminal of a user can establish data communication with a server, the user sends a driving track obtaining instruction to the server through the terminal so as to obtain driving track data from the server, and the server sends the driving track data to the terminal when receiving the driving track obtaining instruction sent by the terminal.
By the driving recording method provided by the embodiment, the original position information point uploaded by the vehicle-mounted positioning device can be further processed, the data transmission quantity of the server and the user terminal is reduced, and the consumption of user traffic is reduced.
[ example 5 ]
As shown in fig. 6, the present invention further provides another embodiment of a driving recording method, where the method steps may be executed by a server, and the method includes:
s10: acquiring N original position information points sent by a vehicle at N time nodes; n is a positive integer;
specifically, a vehicle-mounted positioning device can be installed in the vehicle, and a communication device can be installed on the vehicle-mounted positioning device and can report the original position information point of the vehicle to a server according to a certain frequency. For example, the vehicle-mounted positioning device may send the original location information point of the vehicle to the server at a frequency of 60 times per minute, that is, 60 original location information points corresponding to 60 time nodes are uploaded in one minute. The server can receive and acquire 60 original position information points sent by the vehicle at 60 time nodes.
S201: selecting a first original position information point from the N original position information points according to the sequence of the time nodes as a first effective position information point;
specifically, the first original position information point of the N original position information point clocks can be used as the first effective position information point, so that the comparison can be performed with the subsequent continuous point fetching.
S202: and (P-1) effective position information points are screened from the N original position information points according to the sequence of the time nodes, and the original position information point of the next time node of the last effective position information point is set as the original position information point of the current time node, wherein P is the number of preset peak values, and P is a positive integer smaller than N.
Specifically, when screening effective position information points for N original position information points is just started, since the vehicle is in a starting stage and the vehicle speed is still relatively low at this time, P original position information points (including the first original position information point as the first effective position information point) are continuously taken as effective position information points to reflect the driving track of the vehicle in the starting stage, and since the first effective position information point at the start is already confirmed in step S201, it is sufficient to take (P-1) effective position information points again in step S202.
It should be noted that P represents the number of preset peaks, and the value of P can be determined according to the time required for the vehicle to start and the uploading frequency of the vehicle-mounted positioning device.
S203: judging whether the distance between the original position information point of the current time node and the original position information point of the last time node is smaller than a preset distance or not;
s204: if the distance between the original position information point of the current time node and the original position information point of the previous time node is smaller than the preset distance, the original position information point of the current time node is omitted, the original position information point of the next time node is set as the original position information point of the current time node, and the step S203 is returned to;
s205: if the distance between the original position information point of the current time node and the original position information point of the previous time node is not less than the preset distance, setting the original position information point of the current time node as an effective position information point, setting the original position information point of the next time node as the original position information point of the current time node, and executing S206;
specifically, in steps S203-S205, after the first P valid position information points are extracted, a reference point needs to be extracted according to a determination method of position relation extraction point, that is, as described in steps S203-S205, an original position information point whose distance from the valid position information point of the previous time node exceeds a preset distance is extracted as the valid position information point of the current time node.
S206: judging whether the distance between the original position information point of the current time node and the original position information point of the previous time node is smaller than a default value or not;
s207: if the distance between the original position information point of the current time node and the original position information point of the previous time node is not less than the default value, setting the original position information point of the current time node as an effective position information point and reserving the effective position information point, setting the original position information point of the next time node as the original position information point of the current time node, and returning to execute the step S206;
specifically, after the reference point is taken out in steps S203-S205, it needs to be determined whether the distance between the effective position information point of the current time node and the original position information point of the previous time node is smaller than a default value; the processing is performed by determining whether to perform the processing by time point sampling or distance point sampling.
It is understood that whether the distance between the original location information of the current time node and the original location information of the previous time node is less than the default value may be regarded as an indication of whether the vehicle is running at a high speed. For example, the default value may be 10 meters, and when the distance between the original location information of two adjacent time nodes is greater than 10 meters, it may indicate that the vehicle has reached the standard for high-speed driving, and a distance point-taking manner may be adopted, otherwise, it may indicate that the vehicle is in low-speed driving, and a time point-taking manner should be adopted. The default values may be set according to actual road conditions or traffic code requirements.
In step S207, if the distance between the original position information point of the current time node and the original position information point of the previous time node is not less than the default value, it indicates that the vehicle is in a high-speed moving state, at this time, the point is taken according to the distance taking manner, and since the distance between the original position information point of the current time node and the original position information point of the previous time node is greater than or equal to the default value, the original position information point of the current time node is reserved as an effective position information point. Therefore, if the automobile keeps running at a high speed all the time, effective position information points with uniform distances are taken out when points are taken, the points with uniform distances are displayed on the user terminal, and the user can know that the automobile runs at a high speed in the distance.
S208: if the distance between the original location information point of the current time node and the original location information point of the previous time node is smaller than the default value, go to step S209;
s209: judging whether the time difference between the original position information point of the current time node and the original position information point of the previous time node is greater than the preset time or not;
s2010: if the time difference between the original position information point of the current time node and the original position information point of the previous time node is less than the preset time, the original position information point of the current time node is omitted, the original position information point of the next time node is set as the original position information point of the current time node, and the step S209 is executed again;
s2011: if the time difference between the original position information point of the current time node and the original position information point of the previous time node is not less than the preset time, setting the original position information point of the current time node as an effective position information point, setting the original position information point of the next time node as the original position information point of the current time node, and returning to execute the step S206;
s2012: and after the N original position information are screened, M effective position information is obtained.
Specifically, if it is determined in step S208 that the distance between the original location information point of the current time node and the original location information point of the previous time node is smaller than the default value, the time point-taking method is adopted. The method may perform point fetching according to the embodiment corresponding to fig. 2 in a manner of point fetching according to time.
If the time difference between the original position information point of the current time node and the original position information point of the previous time node is smaller than the preset time, the original position information point of the current time node is omitted, the original position information point of the next time node is set as the original position information point of the current time node, and then whether the time difference between the original position information point of the current time node and the original position information point of the previous time node is smaller than the preset time or not is continuously judged. If the time difference between the original position information point of the current time node and the original position information point of the previous time node is not less than the preset time, setting the original position information point of the current time node as an effective position information point, setting the original position information point of the next time node as the original position information point of the current time node, returning to the step S206, judging whether the distance between the original position information point of the current time node and the original position information point of the previous time node is less than a default value, and further judging whether the original position information point of the next time node is taken according to time or distance.
If the automobile driving speed is always low, the point is taken by adopting the time point taking method in the step S206, then the steps S208 and S209 are executed, after the steps S2010 and S2011 are executed, one point is taken according to the time point taking method, then the step S206 is returned, the time point taking method is judged again, and then the steps S208, S209, S2010 and S2011 are repeatedly executed. Because the running speed of the automobile is slow, effective position information points with close distances can be screened out according to time point taking, when the effective position information points are displayed on a user terminal, dense effective position information point distribution can be displayed on the road section with the traffic jam, and a user can know that the automobile runs slowly on the road section.
S30: generating a driving track of the vehicle according to the M effective position information points;
specifically, the server may perform punctuation on the map according to the effective position information obtained by the screening, and then generate a driving track of the vehicle.
S40: and when a driving track acquisition instruction sent by the terminal is received, sending the data of the driving track to the terminal.
Specifically, a terminal of a user can establish data communication with a server, the user sends a driving track obtaining instruction to the server through the terminal so as to obtain driving track data from the server, and the server sends the driving track data to the terminal when receiving the driving track obtaining instruction sent by the terminal.
The above method will be explained below by way of an example:
for example, 11 original position information points including a (start point, 0 th S, 0 th meter), B (1 st S, 1 st meter), C (2 nd S, 5 th meter), D (4 th S, 10 th meter), E (5 th S, 21 st meter), F (6 th S, 33 th meter), G (8 th S, 42 th meter), H (10 th S, 47 th meter), I (12 th S, 51 th meter), J (13 th S, 52 th meter), K (16 th S, 53 th meter) are collected.
According to S201, first, a first original position information point a is taken as a first valid position information point. Then according to step S202, then S202 will screen out (P-1) effective location information according to the sequence of the time nodes, assuming that the peak value P is 3, then select 2 effective location information points B and C, and set the original location information point D of the next time node as the original location information point of the current time node. Then, S203 is executed, it is determined whether the distance between the original position information point D of the current position information node and the original position information point C of the previous time node is smaller than a preset distance (assuming that the preset distance is 8 meters), if the determination result is smaller than the preset distance, S204 is executed, the original position information point D of the current time node is discarded, then the original position information point E of the next time node is set as the original position information point of the current time node, S203 is executed again to continue the determination, if the determination result is that the distance between the point C and the point E is greater than the preset distance of 8 meters, S205 is executed, the original position information point E of the current time node is set as an effective position information point, and the original position information point F of the next time node is set as the original position information point of the current time node. Then executing step S206, judging whether the distance between the original position information point F of the current time node and the original position information point E of the previous time node is smaller than a default value (the default value is set to be 10 meters), if the judgment result is that the distance between the points E and F is larger than the default value of 10 meters, executing step S207, setting the original position information point F of the current time node as an effective position information point and reserving the effective position information point, setting the original position information point G of the next time node as the original position information point of the current time node, and returning to execute step S206; then, continuously judging whether the distance between the original position information point G of the current time node and the original position information point F of the previous time node is smaller than a default value or not; if the determination result is greater than the predetermined value, step S207 is executed to set the original location information point G of the current time node as the valid location information point and to keep the same, and to set the original location information point H of the next time node as the original location information point of the current time node, and step S206 is executed to continue to determine whether the distance between the original location information point H of the current time node and the original location information point G of the previous time node is less than the default value. If the determination result is that the distance between the G point and the H point is smaller than the default value, step S208 and step S209 are executed to determine whether the time difference between the original position information point H of the current time node and the original position information point of the previous time node is greater than the preset time (the preset time is set to 4S); if the time difference between the point G and the point H is 2 seconds and is less than the preset time, executing step S2010, omitting the point H of the original position information of the current time node, then setting the point I of the original position information of the next time node as the point of the original position information of the current time node, and returning to execute step S209 to determine again whether the time difference between the point I of the original position information of the current time node and the point G of the original position information of the previous time node is greater than the preset time; if the time difference between the G point and the I point is determined to be 4 seconds and not less than the preset time, step S2011 is executed to set the I point, which is the original position information point of the current time node, as the valid position information point, and set the J point, which is the original position information point of the next time node, as the original position information point of the current time node; returning to execute step S206 to determine whether the distance between the original position information point J of the current time node and the original position information point I of the previous time node is less than the default value; if the distance between the point I and the point J is smaller than the default value, executing steps S208 and S209 to determine whether the time difference between the point J of the original position information of the current time node and the point I of the original position information of the previous time node is greater than the preset time; if the judgment result is that the time difference between the point I and the point J is smaller than the preset time, executing step S2010, omitting the original position information point J of the current time node, setting the original position information point K of the next time node as the original position information point of the current time node, and returning to execute step S209 to judge whether the time difference between the original position information point K of the current time node and the original position information point I of the previous time node is larger than the preset time; if the judgment result is not less than the preset value, reserving the original position information point K of the current time node. Thus, the original location information points are all subjected to the screening processing, A, B, C, E, F, G, I, K points are obtained, and D, H, J points are omitted. In the user's terminal, it can be seen that the distance between A, B, C is relatively close, the user can know that the vehicle is traveling relatively slowly in the distance, and the distance between C, E, F, G is relatively far, the user knows that the vehicle is traveling relatively fast in the distance and the road condition is good, and that the distance between G, I, K is relatively close, the user can know that the vehicle is traveling relatively slow in the distance and the road condition is not good.
After the valid position information points are obtained, the following generation of the driving path and the transmission of the data can be completed according to the steps S30 and S40.
Therefore, the method provided by the embodiment can effectively screen the acquired original position information points, reduce the data transmission quantity and ensure the accuracy of the automobile track path.
[ example 6 ]
Embodiment 6 is based on embodiment 5, and step S2051 is further included between steps S205 and S206: setting a count value, wherein the count value is an integer; in step S207, the current count value is assigned to zero; in step S2011, after the step of setting the original location information point of the next time node as the original location information point of the current time node, obtaining a value of the current count value, adding one to the current count value, and assigning the current count value to the current count value, then determining whether the current count value is greater than a preset peak value, if not, executing step S203, and if the current count value is less than the preset peak value, executing step S206.
Specifically, in a special situation, for example, when the vehicle is very congested and the vehicle can hardly run, the point is continuously taken at the same place in the manner of embodiment 5, which results in too many points to be taken and increases the data transmission amount. Therefore, in order to reduce the data transmission amount, a step S2051 is added between steps S205 and S206 in the present scheme: a count value is set.
In step S207, the current counter is cleared, and then step S2011 is executed, the value of the counter is incremented, and then it is determined whether the counter is smaller than the peak value, and if so, the process returns to step S206. Because the vehicle is in the traffic jam state, after step S206, step S208, step S209, step S2010, and step S2011 are executed in a time point fetching manner, and then the counter value is incremented again until the counter value reaches the preset peak value, that is, until the counter value reaches the valid position information points of the preset peak value number, the counter value is forced to be fetched in a distance point fetching manner, that is, step S203 is executed, and then the vehicle is in the traffic jam state, so that the distance between the original position information point of the current time node and the original position information point of the previous time node is smaller than the preset distance, and therefore, only step S204 can be executed, the point can not be fetched until the traffic jam is finished, and the vehicle resumes the normal point fetching after continuing to travel.
Therefore, under the special condition of traffic jam, the original position information points can be further screened by the method of the embodiment, the original position information points repeatedly acquired by the vehicles at the same place are omitted, and the data transmission quantity is further reduced.
