FIG. 1 is a flow chart illustrating a method for displaying a travel path according to an exemplary embodiment of the present application; the embodiment can be used for a client (such as a passenger side APP) or a browser and the like installed on terminal equipment such as a smart phone, a tablet computer and a desktop notebook. As shown in fig. 1, the method comprises steps S101-S103:
s101: a set of path points of a current travel path of a target vehicle is received.
In an embodiment, the target vehicle may be a car appointment reserved by the passenger through the client, or may be a self-driving vehicle of the passenger, and the embodiment is not limited thereto.
In one embodiment, when a passenger waits for a reserved target vehicle or sits in the target vehicle, the passenger can check the traveling path of the target vehicle through a passenger end APP installed on a device such as a smart phone to know the real-time position of the target vehicle.
In an embodiment, the set of waypoints includes a plurality of waypoints, each waypoint corresponding to a target vehicle location.
In an embodiment, a client (i.e., a driver APP) installed on a terminal device held by a driver may report a set of path points of a current driving path of a target vehicle to a server. After the server side obtains the path point set, the server side can perform corresponding processing (such as removing abnormal path points) on the obtained path point set, and send the processed data point set to the passenger side.
It should be noted that, as for the method for the server to perform corresponding processing on the acquired path point set, reference may be made to a method in the prior art, which is not limited in this embodiment. In an embodiment, the server may be a server or a server cluster formed by a plurality of servers.
In an embodiment, the passenger side APP may obtain a set of path points of the current driving path from the service side in an active or passive manner, where:
in an active mode, the passenger side APP may send a path point set acquisition request (e.g., a polling request of a path point set) to the server side, and may further receive the path point set of the current travel path of the target vehicle sent by the server side in response to the request.
And in a passive mode, namely, the passenger side APP can passively receive the path point set of the current running path of the target vehicle sent by the server side.
The current travel route is a part of a route from the starting point of the target vehicle to the current position of the target vehicle, for example, a route from the latest position of the target vehicle previously transmitted by the server to the latest position of the target vehicle transmitted this time.
In one embodiment, the starting point of the target vehicle may be an order taking place of the target vehicle, such as a place for receiving a passenger order for a service order.
S102: and if the path point set meets a preset interpolation condition, interpolating the path point set to obtain an interpolated path point set.
It should be noted that the above path point set obtained by the passenger side from the server side may be reported to the server side through the internet for the driver side APP. However, in practical implementation, the GPS at the driver end sometimes has a problem of being unable to perform positioning, which results in that the current path point cannot be reported, and further, the distance between some points in the set of path points received by the server end is large, which may affect the effect of displaying the subsequent path, and therefore, interpolation needs to be performed on these points with large distance, that is, estimated path points are inserted between two points with large distance.
In one embodiment, an interpolation condition of the route point set may be preset on the passenger side, and after the route point set of the current travel route of the target vehicle is acquired, it is determined whether the acquired route point set satisfies the interpolation condition. If yes, interpolating the path point set to obtain an interpolated path point set; if not, the path point set is not interpolated.
In an embodiment, the preset interpolation condition may be determined according to a preset evaluation parameter of the path point set. For example, after a path point set of the current driving path is obtained, a preset evaluation parameter of the path point set may be calculated, and if a calculation result meets an interpolation requirement, it may be determined that the path point set meets a preset interpolation condition; otherwise, it may be determined that the path point set does not satisfy the preset interpolation condition.
In an embodiment, the manner of determining that the set of path points satisfies the predetermined interpolation condition may also refer to the embodiment shown in fig. 2, which will not be described in detail herein.
In an implementation, when it is determined that the acquired path point set meets the preset interpolation condition, the path point set may be interpolated by using a preset interpolation method to obtain an interpolated path point set.
In an embodiment, the preset interpolation method may be selected by a developer from an existing interpolation algorithm according to actual needs, and this embodiment does not limit this.
In another embodiment, the method for interpolating the path point set can also be referred to the following embodiment shown in fig. 3A, and will not be described in detail here.
S103: and generating the current running path of the target vehicle based on the interpolated path point set, and displaying the current running path.
In an embodiment, after obtaining the interpolated route point set, a current driving route of the target vehicle may be generated based on the interpolated route point set, and the driving route may be displayed on the client of the terminal device. For example, the driving path is displayed on a corresponding road segment of an electronic map in the client.
It should be noted that, the above-mentioned generating a driving route based on the interpolated route point set and displaying the generated driving route on the electronic map may refer to methods in the prior art, and a developer may select from the prior art according to actual business needs.
As can be seen from the above description, in this embodiment, a path point set of a current traveling path of a target vehicle is received, and when the path point set meets a preset interpolation condition, the path point set is interpolated to obtain an interpolated path point set, and then the current traveling path of the target vehicle is generated based on the interpolated path point set, and the current traveling path is displayed. And, because the path point set received by the passenger end from the server end is not processed by interpolation, the received data volume can be reduced, thereby saving the data traffic of the terminal equipment.
FIG. 2 is a flow chart illustrating a method of displaying a travel path according to yet another exemplary embodiment of the present application; the embodiment can be used for a client (namely a passenger side APP) or a browser and the like installed on terminal equipment such as a smart phone, a tablet computer and a desktop notebook. As shown in fig. 2, the method includes steps S201-S204:
s201: receiving a path point set of a current traveling path of a target vehicle sent by a server, wherein the current traveling path is a part of a path from a starting point of the target vehicle to a current position of the target vehicle.
S202: and determining the average deletion time of the sub-paths between every two adjacent path points in the path point set.
In an embodiment, the average deletion time of the sub-paths between two adjacent path points in the set of path points may be calculated according to the following formula (1):
t＝T/(c-1)(1)
wherein, T is the total deletion time of the current driving route, c is the number of route points in the route point set, (c-1) is the number of sub-routes between every two adjacent route points in the route point set, and T is the average deletion time of sub-routes between every two adjacent route points in the route point set.
It should be noted that, in the process of displaying the driving path of the target vehicle on the terminal device, not only the current driving path of the target vehicle may be displayed, but also the driving path that the target vehicle has driven may be displayed differently, that is, the driving path and the driving path may be displayed in different manners.
For example, the travel route that the target vehicle has traveled may be deleted from the map, or the travel route that the target vehicle has traveled may be transparently processed (i.e., the transparency of the travel route that the target vehicle has traveled is increased). In order to present the effect of the two-part synchronization of "target vehicle movement" and "traveled path deletion" on the map, it is therefore necessary to calculate the average deletion time of the sub-path between adjacent waypoints.
S203: and if the average deletion time is greater than or equal to a preset time threshold, determining that the path point set meets a preset interpolation condition, and interpolating the path point set to obtain an interpolated path point set.
In an embodiment, after determining an average deletion time of a sub-path between two adjacent waypoints in the waypoint set, the average deletion time may be compared with a preset time threshold:
if the average deletion time is determined to be greater than or equal to a preset time threshold, determining that the path point set meets a preset interpolation condition, and further interpolating the path point set to obtain an interpolated path point set;
otherwise, the step of interpolating the set of path points is not performed.
S204: and generating the current running path of the target vehicle based on the interpolated path point set, and displaying the current running path.
For the explanation and description of steps S201 and S204, reference may be made to the above embodiments, which are not described herein again.
As can be seen from the above description, in this embodiment, the average deletion time of the sub-path between every two adjacent path points in the path point set is determined, and when the average deletion time is greater than or equal to the preset time threshold, it is determined that the path point set meets the preset interpolation condition, and then the subsequent step of interpolating the path point set may be performed.
FIG. 3A is a flow chart illustrating how a set of path points is interpolated according to an exemplary embodiment of the present application; the present embodiment takes an example of how to interpolate a set of path points on the basis of the above-described embodiments. As shown in fig. 3A, the step S102 of interpolating the set of path points includes the following steps S301 to S302:
s301: and calculating the distance between two adjacent path points in the path point set.
In an embodiment, after determining that the received path point set satisfies the preset interpolation condition, the path point set may be interpolated, that is, the adjacent path points to be interpolated are found from the path point set.
In one embodiment, the adjacent waypoints to be interpolated include two adjacent waypoints whose constituent sub-paths have too long lengths (i.e., the distance between two waypoints), so that the distance between each two adjacent waypoints in the set of waypoints can be calculated separately.
S302: and if the distance is greater than a preset distance threshold value, interpolating the two path points.
In an embodiment, after calculating the distance between every two adjacent waypoints in the waypoint set, the distance between every two adjacent waypoints may be compared with a preset distance threshold respectively. When it is determined that the distance between two adjacent waypoints is greater than the preset distance threshold, the two adjacent waypoints may be determined as the adjacent waypoints to be interpolated, and then the step of interpolating the two waypoints may be performed.
In one embodiment, to further achieve the effect of synchronization between the "target vehicle movement" and the "traveled path deletion" in the above embodiments, the distance threshold may be determined according to the size of a moving object image (e.g., a target vehicle map) displayed on the electronic map, wherein the moving object image may be used to represent the position of the target vehicle on the traveled path.
In an embodiment, the distance threshold may be set as: length of moving object image of 0.5 times reduction multiple of electronic map. For example, if the reduction factor of the electronic map is 20000 (i.e. the scale is 1:20000), and the fixed length of the moving object image shown on the map is 0.006 m (the length may not change with the scale of the ground map), the distance threshold value can be calculated as 0.5 × 0.006 × 20000 — 60 m. That is, when the distance between two adjacent points is greater than 60 meters, the two points may be interpolated.
Fig. 3B is a schematic diagram of a scenario for determining a distance threshold between two adjacent waypoints according to an exemplary embodiment of the present application. Fig. 3C is a schematic view of a scenario for determining a distance threshold between two adjacent waypoints according to another exemplary embodiment of the present application.
As shown in fig. 3B, assume that the length of the sub-path between waypoint a and waypoint B is less than or equal to 0.5 times the length of the target vehicle map 001. After the target vehicle map 001 (i.e., the center point of the target vehicle map 001) moves from the waypoint a to the waypoint B, the electronic map SDK may delete the sub-path between the waypoint a and the waypoint B. Since 0.5 times of the target vehicle map 001 (i.e. the second half of the target vehicle map) can completely cover the sub-path from the waypoint a to the waypoint B, the process of deleting the sub-path is not seen by the user, i.e. the two synchronous effects of "target vehicle movement" and "traveled path deletion" can be achieved.
In contrast, as shown in fig. 3C, if the length of the sub-path between the route point C and the route point D is greater than 0.5 times the length of the target vehicle map 001, when the sub-path between the route point C and the route point D is deleted after the target vehicle map 001 moves from the route point C to the route point D, since the second half of the target vehicle map cannot completely cover the sub-path between the route point C and the route point D, the process of deleting the sub-path is seen by the user, that is, the synchronization of the "target vehicle movement" and the "traveled route deletion" cannot be guaranteed.
Therefore, the above distance threshold is set to: the length of the target vehicle map which is 0.5 times of the reduction multiple of the electronic map can ensure that the distance between every two adjacent waypoints in the waypoint set after interpolation is smaller than the distance threshold value, thereby ensuring the synchronism of the two parts of 'target vehicle movement' and 'traveled route deletion'.
In an embodiment, the manner of interpolating the two waypoints can also be referred to the following embodiment shown in fig. 5, which is not described in detail here.
As can be seen from the above description, in this embodiment, the distance between two adjacent waypoints in the waypoint set is calculated, the distance threshold is determined according to the size of the moving object image, and then when it is determined that the distance between two adjacent waypoints is greater than the preset distance threshold, the two waypoints are interpolated, so that the adjacent waypoints to be interpolated can be accurately found, and further the step of interpolating the two waypoints can be performed.
FIG. 4A is a flow chart illustrating how two waypoints are interpolated according to an exemplary embodiment of the present application; fig. 4B is a schematic diagram illustrating an effect of interpolating two waypoints according to an exemplary embodiment of the present application. The present embodiment is exemplified by how to interpolate two path points on the basis of the above embodiments. As shown in fig. 4A, the interpolation of the two path points in step S302 includes the following steps S401 to S403:
s401: calculating a ratio of the distance between the two waypoints to the distance threshold.
In an embodiment, after determining that the distance between two waypoints in the waypoint set is greater than a preset distance threshold, a ratio of the distance between the two waypoints to the distance threshold may be calculated.
S402: determining a minimum number of path points to be inserted between the two path points based on the ratio.
In one embodiment, after determining the ratio of the distance between the two waypoints to the distance threshold, the minimum number of waypoints inserted between the two waypoints may be determined according to the value obtained by subtracting 1 from the ratio.
For example, if the ratio of the distance between the two waypoints to the distance threshold is N (N is a positive integer), the minimum number of waypoints inserted between the two waypoints may be determined to be (N-1).
It should be noted that if the ratio is not an integer, the ratio may be rounded down, and a value obtained by subtracting 1 from the rounded ratio is determined as the minimum number of path points inserted between the two path points. For example, if the above ratio is calculated to be 5.3, the value 5 is obtained by rounding down the ratio, and it is determined that the minimum number of insertion path points is 5-1 to 4.
S403: inserting at least the minimum number of waypoints between the two waypoints.
In one embodiment, when it is determined that the minimum number of waypoints to insert between the two waypoints is N, at least N new waypoints may be inserted between the two waypoints.
For example, as shown in FIG. 4B, if the path point P0And P1The distance between the two is 240 meters, and the preset distance threshold is 60 meters, the path point P can be determined0And P1The ratio of the distance between the two to the distance threshold is 4, the path point P can be reached0And P1At least 3 new path points P are inserted between2、P3And P4And enabling the distance between the finally obtained adjacent path points to be smaller than a preset threshold value.
In an embodiment, the N new waypoints may be inserted between the two waypoints at equal intervals or at unequal intervals, as long as it is ensured that the distance between the finally obtained adjacent waypoints is smaller than the preset threshold, which is not particularly limited in this embodiment.
As can be seen from the above description, in this embodiment, by calculating a ratio between a distance between two waypoints and the distance threshold, determining a minimum number of waypoints to be inserted between the two waypoints according to the ratio, and further inserting at least the minimum number of waypoints between the two waypoints, interpolation of two adjacent waypoints that need to be interpolated can be achieved, and further, a subsequent step of generating a current travel path of the target vehicle based on the interpolated waypoint set and displaying the travel path can be achieved, which can reduce the calculation amount of the server, achieve the purpose of reducing the calculation load of the server, reduce the received data amount, and save the data traffic of the terminal device.
