Description
Technical Field
The invention relates to the technical field of computers, in particular to a method and a device for displaying a driving track.
Background
Along with popularization of automobiles and road construction, the activity area of car owners is larger, and situations that the car owners are not familiar or do not know roads and cannot find destinations are increased, so that more car owners use car navigators or use electronic map applications or route navigation applications installed on mobile phones to plan routes or navigate routes in the process of going out.
When a vehicle-mounted navigator is used or an electronic map application or a route navigation application installed on a mobile phone is used for route planning or route navigation, a route is recommended according to a destination selected by a user and displayed on a corresponding display interface, the position of the user is located through a GPS, and the current position information of the user is marked on the displayed route, so that the user can know the current position information of the user.
However, in the process of locating and presenting the position information of the vehicle by the GPS, the latest position information of the vehicle is refreshed due to a delay in the GPS location or a time interval between the location information acquisitions, and then the current position information of the user presented on the route to be presented is also refreshed. Generally speaking, when the position information of the vehicle is not updated, the displayed position of the vehicle is not changed, and once the vehicle is refreshed, the displayed position of the vehicle is immediately updated. Because the displacement of the vehicle position information may be large or small, it may be along the route, or it may be because the route changes (lane change, turning, etc.), which may cause the change of the vehicle position information to be a jump when the vehicle position information is updated, or not change along the planned route, or cross a non-route area such as a building block, etc.

Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
In order to solve the technical problem of insufficient accuracy of information presentation of route guidance in the conventional technology, in the present embodiment, a method for displaying a driving track is specifically proposed, which may be implemented by relying on a computer program that can run on a computer system based on von neumann system, where the computer program may be an electronic map based on a terminal device such as a smart phone or an electronic navigation device equipped with a positioning system (e.g., a GPS positioning system) or an application program of route guidance. The computer system may be a terminal device such as a smart phone, a tablet computer, a personal computer, etc. running the computer program.
Specifically, as shown in fig. 1, the method for displaying the driving track includes the following steps S102 to S108:
step S102: and acquiring the current navigation route.
It should be noted that the terminal on which the method for displaying the driving track is based further includes a user terminal or an electronic terminal that can display an electronic map and a navigation route, where the user terminal may be a user terminal corresponding to a vehicle, or an electronic terminal of a user, such as a smart phone.
Under the condition that a user obtains route navigation by inputting a starting point and an end point, a navigation route is calculated according to the starting point and the end point input by the user, and an optimal navigation route is selected from a plurality of calculated navigation routes according to a preset navigation route selection rule (such as shortest route, shortest time consumption, minimum traffic lights and the like) and is displayed on a display interface. And then, acquiring the positioning information of terminal equipment such as a vehicle terminal or a smart phone corresponding to the user in real time, and navigating according to the positioning information acquired in real time and the optimal navigation route.
The current navigation route acquired in this step may be a navigation route acquired by acquiring a specified start point and end point, or a navigation route after recalculation due to yaw in a certain navigation. In this embodiment, it should be noted that the current navigation route may also be a navigation route displayed on a display interface of the electronic terminal.
Specifically, in the application scenario shown in fig. 2, the highlighted route track shown by the number L is the current navigation route of the current route navigation, and the number S is the current driving position of the electronic terminal.
Step S104: and acquiring the positioning information of a first sampling time point and a first positioning point of the current sampling.
In this embodiment, in the process of displaying the navigation route, it is further required to display the positioning information of the electronic terminal or the vehicle corresponding to the user on the navigation route, for example, to identify the location information of the user by displaying the identifier corresponding to the electronic terminal or the vehicle on the display. In this embodiment, when acquiring the position information of the user, the electronic terminal itself corresponding to the user needs to acquire the corresponding positioning information through a positioning system, for example, a vehicle-mounted positioning system, a positioning system of a smart phone, or the like.
It should be noted that, in this embodiment, the location information of the user may be obtained in real time, that is, the location information of the electronic terminal is sent to the server according to the CPU refresh cycle and the location information of the user is updated by the server, or the location information of the electronic terminal is sent to the server by the electronic terminal at regular time according to a preset sampling cycle and then the corresponding location information is updated by the server. Under the condition that the position information of the electronic terminal is updated successfully, one-time updating of the position information of the electronic terminal is called one-time sampling, namely, one-time sampling is carried out on the positioning information of the current position of the electronic terminal, and a sampling time point corresponding to the sampling and positioning information corresponding to a sampling point are obtained, wherein the positioning information can be coordinate information corresponding to the sampling point.
It should be noted that, generally speaking, when a vehicle is traveling along a navigation route, the vehicle or the user must be located on the navigation route, and if the vehicle or the user is not located on the navigation route, a yaw may occur or an error may occur in positioning. In case of yaw, a preset yaw processing flow needs to be triggered for processing. However, if no yaw occurs, but only because of positioning errors, the sampling point is not on the navigation route, and the position of the vehicle or the user is actually on the navigation route; in this case, the deviation between the sampling point corresponding to the current sampling and the navigation route needs to be calculated, and in the case that the deviation is small enough, it can be considered that only the positioning error that is allowed by the accuracy occurs; however, in the case where the deviation between the position of the sampling point and the navigation route exceeds a certain range, it cannot be regarded as a positioning error only within an accuracy allowable range.
Specifically, the distance between the sampling point and the navigation route may be calculated by the positioning information of the sampling point, for example, a minimum value of the distances between the sampling point and all data points included in the navigation route is used as the distance between the sampling point and the navigation route, and in a case that the distance is smaller than a preset distance threshold, it is considered that the position of the user in the current sampling is still in the navigation route, and the yaw phenomenon does not occur.
In the present embodiment, it is necessary to determine whether the currently sampled sampling point (i.e., the first positioning point) is on the navigation route. And if the distance between the positioning information of the sampling point and the time of a certain data point contained in the navigation route is small enough, determining that the sampling point is on the navigation route, and taking the data point as the data point corresponding to the sampling point and replacing the sampling point with the data point.
In another embodiment, the sampling point is also determined to match the navigation route when the distance between the sampling point and the navigation route is within a certain range, taking into account the positioning error. Specifically, the distance between the first positioning point and the navigation route is calculated according to the positioning information of the first positioning point, and when the distance is smaller than a preset distance threshold, it is determined that the first positioning point is matched with the navigation route, and a data point on the navigation route, which is the smallest in distance from the first positioning point, is used as the first positioning point.
Otherwise, when the minimum distance is greater than or equal to the preset distance threshold, determining that the first fixed point is not matched with the navigation route, and triggering a preset yaw processing flow.
Step S106: and comparing the positioning information of the first sampling time point and the first positioning point sampled at present with the positioning information of the second sampling time point and the second positioning point sampled at last time, and determining the sampling time interval corresponding to the current sampling and the sampling interval distance on the navigation route in the sampling time interval.
After the sampling time point corresponding to the current sampling and the positioning information of the corresponding sampling point are obtained, the sampling time point (second sampling time point) obtained by the last sampling and the positioning information of the corresponding sampling point (positioning information of the second positioning point) also need to be obtained. It should be noted that, in this embodiment, when there is no last sampling, the second positioning point may be a starting point of the navigation route; that is, in the first sampling after the start of navigation, there is no previous sampling corresponding thereto, and in this case, the positioning information corresponding to the start point is taken as the positioning information of the second positioning point, and the time at which navigation is started is taken as the second sampling time point.
In the last sampling, the position information of the user terminal at that time is obtained, and the position information of the user terminal is updated to the second positioning point in the displayed navigation route. That is, in the currently displayed display interface of the navigation route, the position of the marker corresponding to the electronic terminal of the user corresponds to the second positioning point.
Between the current sampling and the last sampling, there is a certain time interval between the two samplings, and the user may also have a certain change to the corresponding location, for example, have traveled a certain distance to the destination direction according to the navigation route.
In this embodiment, the sampling time interval corresponding to two times of sampling may be determined by calculating a time difference between a first sampling time point of a current sampling and a second sampling time point of a last sampling. It should be noted that, in this embodiment, the sampling time interval may also be determined according to a sampling period, because the positioning information of the ue may be obtained according to a certain sampling period when obtaining the positioning information of the ue, that is, the sampling time interval may also be directly determined according to the sampling period. Specifically, under the condition that the sampling period is not changed or the positioning information of the user terminal can be successfully acquired by each sampling, the sampling period is consistent with the sampling time interval; however, in the case where the sampling period changes or the acquisition of the positioning information fails during the sampling process for acquiring the positioning information of the user terminal (i.e., the sampling fails), the sampling time interval cannot be determined according to the sampling period, but can be determined only according to the time difference between the first sampling time point and the second sampling time point.
It should be noted that, in this embodiment, when the location information of the user is obtained, the location information of the current location of the user may also be periodically sampled according to a preset sampling period. Specifically, before the step S104, the method further includes acquiring a preset sampling period to sample the position information of the electronic terminal, and acquiring the position information of the sampling time point and the positioning point corresponding to the sampling.
It should be noted that the preset sampling period may be a preset fixed sampling period, for example, 1s, and in another alternative embodiment, the preset sampling period may also be calculated according to the road condition or the driving speed. That is, in this case, the sampling period may be determined according to the road condition, whether turning or lane changing is required, or the like, or the shape of the route, or the like, or the form speed of the user.
Further, in a specific embodiment, the process of determining the sampling period may be: acquiring the current road condition reference value, wherein the road condition reference value at least comprises a congestion reference value; acquiring the running speed of the electronic terminal; and determining the sampling period according to the road condition reference value and/or the driving speed of the electronic terminal.
That is, when determining one sampling period, the determination may be made according to the current road condition (e.g., congestion reference value, weather, route track shape), the traveling speed of the user, and the like. Under the conditions of road condition congestion and slow running, a larger sampling period can be selected; under the conditions of good road conditions and high driving speed, a smaller sampling period can be selected.
Specifically, the corresponding sampling period may be calculated according to a preset sampling period calculation algorithm, with the road condition reference value and the driving speed as input, with the calculated sampling period as the sampling period, and sampling may be performed using the sampling period.
Further, according to the positioning information of the first positioning point and the positioning information of the second positioning point, the moving distance of the electronic terminal corresponding to the user in the sampling time interval, that is, the sampling interval distance, can be determined. For example, the distance between the first positioning point and the second positioning point may be calculated as the sampling interval distance. It should be noted that, in this embodiment, because the user is moving or driving along the navigation route or along the road, and the route may not be all straight lines (for example, the route may be a curve, or there are behaviors such as turning, turning around, etc.), and the trajectory moved by the user may not be all straight lines, when calculating the sampling interval distance at the sampling time interval, it is necessary to calculate the distance between the first positioning point and the second positioning point based on the navigation route, that is, the length of the trajectory that the user terminal needs to pass through when moving from the second positioning point to the first positioning point along the navigation route is the sampling interval distance.
Step S108: and calculating the moving speed according to the sampling time interval and the sampling interval distance, and moving the marker corresponding to the electronic terminal from the second positioning point to the first positioning point along the navigation route according to the moving speed when the navigation route is displayed.
After the moving distance of the user terminal within the sampling time interval is determined, the time taken for the user terminal to move from the second positioning point to the first positioning point can be determined. Therefore, when the identifier corresponding to the user terminal is displayed on the displayed navigation route, in order to accurately display the specific situation that the user drives or moves within the sampling time interval, the identifier can be moved from the second positioning point to the first positioning point in a uniform speed manner, and the identifier is moved along the navigation route, and the time taken is consistent with the sampling time interval. That is to say, the moving speed is calculated through the sampling time interval and the sampling interval distance, and then the marker is moved from the second positioning point to the first positioning point along the navigation route at a constant speed according to the moving speed, so that the situation that the user cannot accurately display the real situation in the driving process due to the fact that the position information of the corresponding marker on the displayed electronic map is directly updated in a jump mode after the position of the user terminal is updated is avoided.
Further, in another alternative embodiment, the movement of the marker in the sampling time interval may also be implemented in the form of an animation, that is, in this step, the position of the marker at each time point in the sampling time interval is calculated by the movement speed, then a corresponding animation is generated and displayed, and then after the animation is played, the position of the marker is consistent with the position of the first positioning point on the display interface of the navigation route.
In the present embodiment, if the user is traveling along the navigation route, and if the traveling road has no intersection or the like, the user does not have a yaw phenomenon during the sampling of the position information of the user. For example, in a highway segment without a branch, ramp, etc., it is unlikely that yaw will occur. However, if there is an intersection, the user may miss the driving direction given by the navigation route or the user may change the driving direction by himself or herself, which may cause a yaw, requiring a recalculation of the navigation route.
In this embodiment, the navigation route may be segmented according to the data feature points such as the road condition and the intersection, the number of sampling times may be reduced in the straight-going road segment with good road condition and no intersection, and the number of sampling times of the position information of the user may be increased in the intersection or the road segment where the navigation route indicates turning. That is, the sampling scheme for the positioning information can be intelligently selected according to the specific distribution of the road conditions and/or the routes.
Specifically, the step S102: after the current navigation route is obtained, the method further comprises the following steps: at least one segmented route included with the navigation route is obtained.
The segmented route corresponding to the navigation route can be obtained by segmentation processing of the server or can be obtained by segmentation processing of the electronic terminal according to the navigation route. In this embodiment, the acquisition of the segment route may be divided according to the intersection, the branch road, and the like included in the navigation route.
Specifically, the obtaining of at least one segment route included in the navigation route includes: acquiring at least one data characteristic point corresponding to the navigation route, and dividing the navigation route into at least one sectional route according to the at least one data characteristic point; the at least one data feature point includes at least a data point for identifying a turn event or intersection location on the navigation route.
That is, after the navigation route is acquired, all the data feature points included in the navigation route, such as data feature points of intersections, branch intersections, traffic lights, high-speed entrances, and the like, are acquired. And then dividing the navigation route into a plurality of sectional routes according to the data characteristic points. For example, when the number of the data feature points is N, the navigation route is divided into N +1 segment routes by performing segmentation processing once for each data feature point.
In the embodiment, sampling is performed at least once on each subsection route, that is, each subsection route at least comprises one sampling point; in another alternative embodiment, each segmented route may also contain at least 2 sampling points.
That is, there is at least one sampling before and after each data feature point as the identifier of the electronic terminal moves along the navigation route, so that it can be determined in time whether the user is yawing.
Specifically, before the obtaining the positioning information of the first sampling time point and the first positioning point of the current sampling, the method further includes: and under the condition that the marker corresponding to the electronic terminal moves to a target sectional route, sampling the positioning information of the electronic terminal, wherein the sampling is performed at least once on the target sectional route.
In another optional embodiment, before the acquiring the location information of the first sampling time point and the first positioning point of the current sampling, the method further includes: under the condition that the marker corresponding to the electronic terminal moves to a target sectional route, determining a sampling period corresponding to the target sectional route; and sampling the positioning information of the electronic terminal according to the sampling period.
That is, for each segment route, when sampling of positioning information is performed in the segment route, sampling is performed at a sampling period corresponding to the segment route; that is, each segmented route has a sampling period with matched threshold, and the sampling period may be determined according to the road condition, whether turning or lane changing is needed, or according to the shape of the route.
Further, in a specific embodiment, the process of determining the sampling period may be: acquiring road condition reference values of the target segmented route, wherein the road condition reference values at least comprise congestion reference values; acquiring the driving speed of the electronic terminal; and determining a sampling period corresponding to the target segmented route according to the road condition reference value of the target segmented route and the driving speed of the electronic terminal.
That is, when determining the sampling period corresponding to a segmented route, the determination may be performed according to the current road conditions (e.g., congestion reference value, weather, route track shape) of the segmented route, the traveling speed of the user, and the like. Under the conditions of road condition congestion and slow driving, a larger sampling period can be selected; under the conditions of good road conditions and high driving speed, a smaller sampling period can be selected.
Specifically, the corresponding sampling period may be calculated according to a preset sampling period calculation algorithm, with the road condition reference value and the driving speed as input, with the calculated sampling period as the sampling period of the target segment route, and the sampling period is adopted for sampling on the target segment route.
In another optional embodiment, in order to make a user more intuitively know about the remaining routes in the navigation route on the display interface for displaying the navigation route, in this embodiment, the route that has already been traveled is subjected to a graying process.
Specifically, the obtaining of the current navigation route further includes: highlighting the navigation route in a highlighting mode on a display interface of the electronic terminal. That is, when the navigation route is displayed, in order to distinguish the difference between the current navigation route and other routes in the electronic map, the navigation route is displayed in a highlighted manner, for example, the navigation route is displayed in a manner of being bolded and marked with a designated color, so that the user can intuitively know the details of the navigation route on the electronic map.
Further, in the process of moving the marker corresponding to the electronic terminal from the second positioning point to the first positioning point along the navigation route according to the moving speed, the highlighted display of the route on the navigation route through which the marker moves can be cancelled along with the movement of the marker. That is, for a road segment that has already been traveled, the highlighting of that road segment is cancelled. Specifically, the position of the current marker on the navigation route is acquired, the route which has been driven by the current marker and the route to be driven are determined according to the position, and then the highlight display of the route which has been driven by the current marker is cancelled or the dust wiping treatment is carried out. It is possible for the user to know the route traveled and the route not yet traveled from the displayed navigation route.
