Description
Technical Field

Background
With the development of technology, more and more vehicles are equipped with a Positioning device such as a GPS (Global Positioning System) so that the position information of the vehicle can be displayed on a map. In the prior art, in order to further display the driving track of a vehicle on a map, longitude and latitude data information uploaded by the vehicle can be marked into corresponding track points on the map according to a certain time interval, and then the track points in a period of time are connected by lines, so that a curve, namely the driving track of the vehicle, is obtained. The user can review (or playback, play) the trajectory curve on the screen, thereby achieving the purpose of monitoring, etc.
However, the inventor finds that actual requirements of various users are different in reality, when the user only needs to see a rough driving route of a vehicle, the track display mode in the prior art can meet the requirements, but when the user needs to completely monitor the running process of the vehicle (for example, for the purpose of judging whether the working efficiency of employees is qualified or not), a simple dotting and connecting line display mode in the prior art cannot meet the requirements necessarily under the scene, and particularly under some complex conditions, such as the situation of track crossing or track overlapping, only a curve can be seen through the prior art, the real driving process of the vehicle cannot be known, and the user cannot obtain accurate track information.

Detailed Description
Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present invention. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the invention, as detailed in the appended claims.
FIG. 2 is a flowchart illustrating a method of track viewing according to an exemplary embodiment of the present invention. The method in the embodiment can be used for devices such as mobile phones, tablet computers, desktop computers, laptop portable computers, vehicle-mounted computers, servers, automobile data recorders and navigators.
Referring to fig. 2, the method may include:
in step S201, a plurality of coordinate point data of a moving object is obtained, where each coordinate point data includes coordinate point position information and time information corresponding to the position information.
By way of example, the moving object may be a vehicle (e.g., a bicycle, an electric bicycle, a car, a truck, etc.) or an aircraft, etc.
Taking vehicles and servers as an example, as shown in fig. 3, a vehicle-mounted GPS hardware device may be installed in each vehicle, and the GPS device uploads longitude and latitude, speed, acceleration, and other information of the vehicle at that time to a back-end server directly or through a network every few seconds. The back-end server stores the data into a database and performs certain preprocessing on the data, such as cleaning off coordinate points which are too far away.
Step S202, generating the trajectory of the moving object according to the position information of the plurality of coordinate point data.
The back-end server provides a series of coordinate point data in time sequence, and the front-end connects the points on a display page and then displays the points according to a preset pattern.
Step S203, acquiring an icon corresponding to the moving object.
The specific type of icon is not limited in the embodiment of the present invention, and may be, for example, a vehicle icon (the head of the vehicle points to the driving direction), or a simple arrow, etc., as shown in fig. 4.
Step S204, the moving object is represented by the icon, and the motion process of the moving object is reproduced on the track according to the time information of the coordinate point data.
The embodiment is not limited to how to reproduce the moving process of the moving object on the trajectory, and those skilled in the art can select and design the moving object according to different requirements/different scenarios, and these choices and designs can be used herein without departing from the spirit and scope of the present invention.
In the embodiment of the invention, when the motion trail of the moving object such as a vehicle is displayed to the user, the real motion process of the moving object is reproduced along the track curve instead of simply displaying the track curve, so that even if a complex path is encountered and abnormal points (namely track points are repeated, such as track staggering or track overlapping), the user can still clearly know the real driving process, and the accurate motion trail of the moving object is mastered.
For the method shown in fig. 2, there may be no trigger condition, i.e. the course of motion of the moving object is reproduced on the trajectory by the icon in any case; there may also be a trigger condition, which triggers again under a specific condition (for example, when tracks overlap or are staggered), and the following example supplements the trigger condition of the method according to the embodiment of the present invention:
in this embodiment or some other embodiments of the present invention, before the acquiring the icon corresponding to the moving object, the method may further include:
judging whether the track meets a preset condition or not;
if the track meets the preset condition, the step of obtaining the icon corresponding to the moving object and the subsequent steps are executed, or if the track meets the preset condition, prompt information is sent to a user, and whether the step of obtaining the icon corresponding to the moving object and the subsequent steps are executed is determined according to feedback of the user to the prompt information.
As an example, the preset condition may include:
the track comprises repeated track points, wherein the repeated track points are at least separated from each other for a preset time, are in a non-stop state and are within a preset distance from each other.
For example, all track points can be traversed to find track points which are separated by more than 10 minutes, are in a non-stop state and are located in a close position (for example, within 50 meters), and the track points can be regarded as places repeatedly passed by in the running process of the vehicle. After a certain de-weighting process is performed on these repeated track points, the vehicle running direction (direction can be obtained by comparing with the positions of the front and rear track points) at these points is determined. If the direction angles are basically consistent, the path overlapping can be regarded as the position, and the positions of the front track point and the rear track point are compared, so that the overlapped track segment can be obtained; if the direction angle difference is relatively large, the position is regarded as a path crossing point.
In this embodiment or some other embodiments of the present invention, the sending the prompt message to the user may include:
displaying a label, a button or a floating window on the track;
correspondingly, the determining whether to execute the steps of obtaining the icon corresponding to the moving object and the following steps according to the feedback of the user to the prompt message may include:
and determining whether to execute the steps of acquiring the icon corresponding to the moving object and the later steps according to the operation of the user on the label, the button or the floating window.
Therefore, the page prompt is carried out at the position where the paths are overlapped or staggered, so that the user can conveniently check and follow-up operation.
The following will illustrate how to reproduce the motion process of the moving object on the trajectory:
i) in a scenario, the reproducing the motion process of the moving object on the trajectory according to the time information of the plurality of coordinate point data may include:
and driving the icon to move along the track at a preset speed according to the time sequence of the coordinate points in the track.
A preset speed of movement of one icon may be set in advance so that the icon moves at a constant speed along the trajectory when reproduced.
ii) in another scenario, the reproducing the motion process of the moving object on the trajectory according to the time information of the plurality of coordinate point data may include:
calculating the real-time speed of the moving object at each coordinate point according to the position information and the time information of each coordinate point data;
and driving the icon to move along the track according to the time sequence of the coordinate points in the track and at the real-time speed of the coordinate points.
The advantage of this method of real-time speed is more real, and the disadvantage is that the speed may appear too fast or too slow when reproducing, for which the scale of the map may be adjusted appropriately or the real-time speed may be mapped to the real-time speed adapted to the map, and the detailed description will not be repeated.
In addition, for the two scenes of i) and ii), some functions interacting with the user can be added, so that the user can play back the whole track, or can select a certain track to play back alone, and operations such as adjusting the play speed, pausing or continuing can be performed in the playback process. Thus, the reproducing the moving course of the moving object on the trajectory based on the time information of the plurality of coordinate point data may further include:
receiving an operation instruction for adjusting the moving speed, pausing or continuing of the icon,
and/or (c) and/or,
receiving an operation instruction for reproducing a motion process of a specified track segment in the track;
and adjusting the movement of the icon according to the operation instruction.
As an example, see fig. 5, in which fig. 5 the user may control the movement of the vehicle icon by clicking on a play, fast forward, etc. button.
iii) in still another scenario, the reproducing the motion process of the moving object on the trajectory according to the time information of the plurality of coordinate point data may include:
and adding a plurality of icons to the track according to the time sequence of the coordinate points in the track to indicate the movement direction.
Assuming that the icons representing the moving objects are various arrows (fig. 6 gives an example of two arrows), adding a plurality of arrows on the trajectory for indicating the actual driving process can also solve the problem of unclear path when the trajectory is staggered.
In the embodiment of the invention, when the motion trail of the moving object such as a vehicle is displayed to the user, the real motion process of the moving object is reproduced along the track curve instead of simply displaying the track curve, so that even if a complex path is encountered and abnormal points (namely track points are repeated, such as track staggering or track overlapping), the user can still clearly know the real driving process, and the accurate motion trail of the moving object is mastered.
The following are embodiments of the apparatus of the present invention that may be used to perform embodiments of the method of the present invention. For details which are not disclosed in the embodiments of the apparatus of the present invention, reference is made to the embodiments of the method of the present invention.
FIG. 7 is a schematic diagram illustrating a track-viewing device in accordance with an exemplary embodiment of the present invention. The device in the embodiment can be used for equipment such as mobile phones, tablet computers, desktop computers, laptop portable computers, vehicle-mounted computers, servers, automobile data recorders and navigators.

By way of example, the moving object may be a vehicle (e.g., a bicycle, an electric bicycle, a car, a truck, etc.) or an aircraft, etc.
A trajectory generating module 702, configured to generate a trajectory of the moving object according to the position information of the plurality of coordinate point data.
The back-end server provides a series of coordinate point data in time sequence, and the front-end connects the points on a display page and then displays the points according to a preset pattern.
An icon obtaining module 703 is configured to obtain an icon corresponding to the moving object.
A reproducing module 704, configured to represent the moving object with the icon, and reproduce a motion process of the moving object on the trajectory according to the time information of the coordinate point data.
The embodiment is not limited to how to reproduce the moving process of the moving object on the trajectory, and those skilled in the art can select and design the moving object according to different requirements/different scenarios, and these choices and designs can be used herein without departing from the spirit and scope of the present invention.
Optionally, the module such as the icon obtaining module may be triggered again under a specific condition (for example, when tracks overlap or are staggered), so in this embodiment or some other embodiments of the present invention, the apparatus may further include:
a trigger judgment module for: after the track generation module generates a track, judging whether the track meets a preset condition; if the track meets the preset condition, the icon acquisition module and the reproduction module are allowed to be triggered, or if the track meets the preset condition, prompt information is sent to a user, and whether the icon acquisition module and the reproduction module are allowed to be triggered is determined according to feedback of the user to the prompt information.
As an example, the preset condition may include:
the track comprises repeated track points, wherein the repeated track points are at least separated from each other for a preset time, are in a non-stop state and are within a preset distance from each other.
In a specific scene, all track points can be traversed, track points which are separated by more than 10 minutes, are in a non-stop state and are located at a close position (within 50 meters for example) are found, and the track points can be regarded as places repeatedly passed by in the running process of a vehicle. After a certain de-weighting process is performed on these repeated track points, the vehicle running direction (direction can be obtained by comparing with the positions of the front and rear track points) at these points is determined. If the direction angles are basically consistent, the path overlapping can be regarded as the position, and the positions of the front track point and the rear track point are compared, so that the overlapped track segment can be obtained; if the direction angle difference is relatively large, the position is regarded as a path crossing point.
In this embodiment or some other embodiments of the present invention, when the trigger determining module sends the prompt message to the user, the trigger determining module may be specifically configured to:
displaying a label, a button or a floating window on the track;
correspondingly, when the triggering judgment module determines whether to allow triggering of the icon acquisition module and the reproduction module according to the feedback of the user to the prompt information, the triggering judgment module may be specifically configured to:
and determining whether the icon acquisition module and the reproduction module are allowed to be triggered or not according to the operation of the user on the label, the button or the floating window.
Therefore, the page prompt is carried out at the position where the paths are overlapped or staggered, so that the user can conveniently check and follow-up operation.
The following will illustrate how to reproduce the motion process of the moving object on the trajectory:
in one scenario, the rendering module may be configured to:
and driving the icon to move along the track at a preset speed according to the time sequence of the coordinate points in the track.
A preset speed of movement of one icon may be set in advance so that the icon moves at a constant speed along the trajectory when reproduced.
In another scenario, the rendition module may be configured to:
calculating the real-time speed of the moving object at each coordinate point according to the position information and the time information of each coordinate point data;
and driving the icon to move along the track according to the time sequence of the coordinate points in the track and at the real-time speed of the coordinate points.
The advantage of this method of real-time speed is more real, and the disadvantage is that the speed may appear too fast or too slow when reproducing, for which the scale of the map may be adjusted appropriately or the real-time speed may be mapped to the real-time speed adapted to the map, and the detailed description will not be repeated.
In addition, for the above two scenes, some functions interacting with the user can be added, so that the user can play back the whole track, or can select a certain section of track to play back alone, and operations such as adjusting the play speed, pausing or continuing can be performed in the playback process.

In yet another scenario, the rendition module may be configured to:
