The terminal 102 may be, but not limited to, various personal computers, notebook computers, smartphones, tablet computers, displays and portable wearable devices, and the server 104 may be implemented by a stand-alone server or a server cluster composed of a plurality of servers.
Referring to fig. 2 and 3, fig. 2 is a flow chart of an embodiment of a display method of a map of the present application, and fig. 3 is a schematic view of a scene of an embodiment of a map of the present application. Note that, the display method of the map image illustrated in the present embodiment is not limited to the following steps:
s201: and periodically acquiring a real-time parameter combination of the movable target at intervals of a preset duration, wherein the real-time parameter combination comprises a real-time position parameter and a real-time parameter of the movable target.
In this embodiment, the real-time parameter combination of the movable target is obtained once every preset time interval, so that the real-time position information of the movable target is obtained. The real-time parameter combination comprises a real-time position parameter and a real-time parameter of the movable target.
The movable object may be a user or a vehicle or the like as set forth in the foregoing. The real-time position parameter represents the current position of the movable target, which can be represented by longitude and latitude, custom coordinates and the like, and is not limited herein. The real-time parameter refers to a time when the real-time position parameter is acquired, and the real-time parameter may be represented by a time stamp, a time of a designated time zone, or the like, which is not limited herein. This means that the real-time parameter combination is used to represent the position of the movable object at the moment represented by the real-time parameter.
The preset time period may be 5s, 10s, 15s, 30s, 45s, etc., which is not limited herein.
It should be noted that, the acquiring described in the present application may refer to actively capturing the real-time parameter combination from the movable target, or may be passively receiving the real-time parameter combination by sending the real-time parameter combination from the movable target at each preset time interval, which is not limited herein.
S202: and comparing the map position parameters of the target marks in the map with the real-time position parameters, wherein the target marks are used for marking the movable targets in the map.
In this embodiment, after the real-time parameter combination of the movable target is obtained, whether the position of the target identifier in the map is matched with the current position of the movable target, that is, whether positioning offset occurs, can be determined according to the real-time parameter combination of the movable target and the map position parameter of the target identifier, so that the position of the target identifier can be corrected in time when the positioning offset occurs.
The map position parameter is used for representing the position of the target mark in the map at the current moment. When the target mark changes along with the real-time position of the movable target, the picture position parameter also changes. It is easy to understand that the map location parameter and the real-time location parameter are respectively used to represent a geographic location, and may be both for a real geographic environment and a map of an electronic map, which are not limited herein.
As illustrated in fig. 3, the map plane 300 is a map plane of a resulting electronic map drawn from road surface information of a real geographical environment or the like, and the object identification a is illustrated in the map plane 300 so that a user can observe the position of a movable object. In some cases, the real-time position parameter of the movable object may correspond to the position B of the map 300, which may be a case of a positioning offset, or may be that the acquired real-time position parameter has an error, so in order to facilitate the user to observe the position of the movable object and determine the position where the object identifier should exist, a judgment needs to be made in this case, that is, the map position parameter and the real-time position parameter are compared.
S203: and in response to the distance between the two being smaller than the first distance threshold value, keeping the target mark to stay at the current position in the map plane.
In this embodiment, if the drawing position parameter of the target identifier and the real-time position parameter of the movable target are calculated, it is determined whether the distance between the drawing position parameter and the real-time position parameter is smaller than the first distance threshold. And judging whether the distance between the position of the target mark and the position represented by the real-time position parameter is smaller than a first distance threshold value.
The distance between the position of the target identifier and the position represented by the real-time position parameter may be the distance on the map surface, or may refer to the distance corresponding to the real geographic environment. If so, the risk that the position represented by the real-time position parameter is an error position can be reduced, and the method is also beneficial to planning the path of the target mark moving on the map surface.
If the distance between the two is smaller than the first distance threshold, the acquired real-time position parameter is considered to have errors possibly due to positioning precision and other reasons; or, due to reasons such as current path planning precision and algorithm precision, when the distance between the two is too small, the path for accurately moving the target mark cannot be planned, which is usually represented by continuous jump of the target mark, so that the user cannot be assisted in determining the position of the movable target, even the judgment of the user is interfered, and the display effect of the map is poor.
Therefore, in the map image display method in the implementation, when the distance between the position of the target mark and the position represented by the real-time position parameter is smaller than the first distance threshold value, the target mark is kept to stay at the current position in the map image, so that the risk of jumping of the target mark on the map image can be reduced, the display effect of the map image can be improved, and the use experience of a user can be improved.
It should be noted that, in an embodiment, completing steps S201 to S203 may consider that the current flow is completed and wait for the next real-time parameter combination. In an alternative embodiment, further policy decisions may be continued to determine whether to plan the location of the path of movement update target identity, as will be illustrated below.
Referring to fig. 3 to 5 in combination, fig. 4 is a flowchart illustrating another embodiment of a display method of a map of the present application, and fig. 5 is a schematic view of a scene of an embodiment of moving an object identifier of the present application. Note that, the display method of the map image illustrated in the present embodiment is not limited to the following steps:
s401: and periodically acquiring the real-time parameter combination of the movable target at intervals of a preset duration.
In this embodiment, the real-time parameter combination of the movable target is actively/passively acquired once every preset time period, so that the real-time position of the movable target is known. The real-time parameter combination comprises a real-time position parameter and a real-time parameter of the movable target.
S402: comparing the map location parameters with the real-time location parameters.
In this embodiment, after the real-time parameter combination of the movable object is obtained, the map position parameter of the object identifier in the map may be compared with the real-time position parameter. And judging whether the position of the target mark in the map image is matched with the current position of the movable target or not according to the real-time parameter combination of the movable target and the image position parameter of the target mark, namely whether positioning offset occurs or not, so that the position of the target mark can be corrected in time when the positioning offset occurs.
As illustrated in fig. 3, map plane 300, target identification a, and location B represented by the real-time location parameters; in this embodiment, the position B is shown for the sake of understanding, and the identifier of the position B is not displayed on the map surface.
S403: and judging whether the distance between the picture position parameter and the real-time position parameter is smaller than a first distance threshold value.
In this embodiment, the distance between the map position parameter and the real-time position parameter can be regarded as the distance between the positions respectively represented by these two parameters.
In response to the distance between the position of the target mark and the position represented by the real-time position parameter being smaller than the first distance threshold, the position represented by the real-time position parameter is considered to be the position where the error is likely to be obtained/the target mark cannot be controlled to move smoothly and on the road, and step S404 is executed; in response to the distance between the location of the target identity and the location represented by the real-time location parameter being not less than the first distance threshold, it is considered that the location represented by the real-time location parameter is not the location where the error is derived, step S408 is performed.
When the first distance threshold refers to a distance corresponding to the real geographic environment, the first distance threshold may be 10m, 15m, 20m, 25m, 30m, etc., which will not be described herein.
In an alternative embodiment, step S404 may also be performed when the distance between the location of the target identifier and the location indicated by the real-time location parameter is equal to the first distance threshold, which is not strictly limited herein.
S404: the target mark is kept to stay at the current position in the map plane.
In this embodiment, in response to the distance between the two being smaller than the first distance threshold, the target identifier is kept to stay at the current position in the map plane, so as to further determine whether the real-time position parameter is likely to be caused by an error, and/or facilitate accurate, smooth and road-grabbing of the planned moving path of the target identifier.
S405: a number of real-time parameter combinations are acquired.
In this embodiment, when the distance between the real-time position parameter and the map position parameter is smaller than the first distance threshold, the real-time parameter combination may be waited for again, and it is determined whether the position of the target identifier needs to be matched with the real-time position of the movable target by combining at least two real-time parameter combinations.
Optionally, when the distance between the real-time position parameter and the map position parameter is detected to be smaller than the first distance threshold for the first time, the real-time parameter combination may still be acquired in a preset duration, or the frequency of acquiring the real-time parameter combination may be increased, which is not limited herein.
The number of real-time parameter combinations acquired in this step may be one, two, three, four, five, etc., and is not limited herein.
S406: and taking the real-time position parameters acquired at the latest moment as planning end points, taking a plurality of previous real-time position parameters as reference positions, planning a moving path from the current position of the target mark to the position of the planning end point on the map surface, and taking the path according to each reference position of the path.
In this embodiment, after having at least two real-time parameter combinations, the real-time position parameter acquired at the latest time may be determined based on the real-time parameter included in the real-time parameter combinations, and the real-time position parameter acquired at the latest time may be used as a planning destination to plan a movement path from the position represented by the map position parameter to the planning destination.
When planning a moving path for road-holding on a map, it is necessary to use a real-time position parameter, which is not used as a planning destination, as a reference position. In other words, at least one real-time position parameter other than the real-time position parameter as the key point of planning is taken as the reference position, the moving path of the road-holding on the map surface is planned, and the moving path should be routed to each reference position. If so, at least one reference position is added between the starting point and the end point of the moving path, which is beneficial to improving the reliability and the accuracy of planning the moving path.
Alternatively, all real-time position parameters except the real-time position parameters serving as the key points of planning can be used as reference positions, so that the reliability and accuracy of planning the moving path can be improved.
As illustrated in fig. 5, the target identifier a identifies a position represented by the drawing position parameter, the real-time position parameter K is a real-time position parameter in which the distance between the real-time position parameter K and the drawing position parameter is detected for the first time to be smaller than the first distance threshold, and the real-time position parameter a' is a real-time position parameter acquired again. And taking the real-time position parameter K as a reference position, taking the real-time position parameter A 'as a planning end point, and planning a moving path from the drawing position parameter A to the real-time position parameter A' through the real-time position parameter K, wherein the moving path can be shown as a dash-dot line in the drawing.
S407: and judging whether the movement rule of the target mark is satisfied.
In this embodiment, in response to the movement rule of the target identifier being satisfied, the movement path is considered to be feasible, and the target identifier may be allowed to move on the map surface, step S409 is performed; in response to the movement rule of the target mark not being satisfied, it is considered that the discrepancy between the acquired real-time position parameter and the map position parameter may be caused by an error, and step S404 is performed.
Specifically, the movement rule of the target mark is that the length of the movement path is greater than the second distance threshold, if the real-time position parameter is considered to be possibly truly inconsistent with the map position parameter, the real-time position parameter is not caused by error, and therefore the reliability and the accuracy of planning the movement path are improved. For example, the second distance threshold may be 5m, 7.5m, 10m, 15m, 20m, etc.
Further, the movement rule may further include that a linear distance between the planned endpoint and the map location parameter of the target identifier is greater than a third distance threshold, the third distance threshold being less than the second distance threshold; and/or calculating the moving speed of the movable target based on the real-time position parameters and the real-time parameters acquired for a plurality of times, wherein the moving speed is greater than a speed threshold. That is, the above condition needs to be satisfied while the length of the moving path is greater than the second distance threshold.
Specifically, the movement plan may be: and when the length of the moving path is larger than the second distance threshold, the linear distance between the planning endpoint and the drawing position parameter of the target mark is larger than the third distance threshold. Alternatively, the moving speed of the movable target is greater than the speed threshold while the length of the moving path is greater than the second distance threshold. Or when the length of the moving path is larger than the second distance threshold, the linear distance between the planning endpoint and the drawing position parameter of the target mark is larger than the third distance threshold, and the moving speed of the movable target is larger than the speed threshold.
S408: the planning target marks a moving path from the current position to the real-time position parameter on the map surface for road capturing.
In this embodiment, when the distance between the map location parameter and the real-time location parameter is not less than the first distance threshold, a moving path from the map location parameter to the real-time location parameter may be planned, i.e. a moving path from the current location of the planning target identifier to the real-time location parameter for capturing a path on the map.
S409: the control target mark moves along the moving path on the map surface.
In the present embodiment, the control target mark moves along the movement path on the map surface. The movement path may be the movement path determined in the completion step S407 to satisfy the movement rule, or may be the movement path directly planned in the completion step S408, which is not limited herein.
As illustrated in fig. 5, the control target identity is moved from the map position parameter a to the real-time position parameter a 'along the movement path, taking the real-time position parameter a' as the new map position parameter a.
In an alternative embodiment, the movement path movement may be the movement path planned by the movement path in step S406, without performing the determination in step S407.
Therefore, the planned moving path in this embodiment can reduce the risk of lower reliability and accuracy of path planning as much as possible, and can also consider whether the path is an error condition, so as to reduce the risk of jumping the target mark on the map, thereby being beneficial to improving the display effect of the map and further improving the use experience of the user. And after each time a new point location of the movable target is acquired, the position of the movable target is checked first. Meanwhile, after each time of monitoring the change of the heartbeat data (real-time parameter combination), the position of the target mark is not directly refreshed, and the position of the current target mark on the map is combined and processed through layer-by-layer calculation, so that the reliability of the map display is provided.
In some embodiments, the "periodically acquiring the real-time parameter combination of the movable object at intervals of the preset duration" described in step S201 and step S401 in the above embodiments may have a position represented in the acquired real-time parameter combination, which is located on a path (i.e., a past path) where the movable object has moved, and for this reason, the following determination method is described in this application, to distinguish whether the real-time position parameter is caused by an error or is a real movement path of the movable object.
Referring to fig. 6, fig. 6 is a flowchart illustrating an embodiment of a method for acquiring real-time parameter combinations of a movable object according to the present application. It should be noted that, the method for acquiring the real-time parameter combination of the movable object described in the present embodiment is not limited to the following steps:
s601: it is determined whether the acquired real-time location parameter is located in a past path of the movable object.
In the present embodiment, in response to the acquired real-time position parameter being located in the past path of the movable target, it is considered that it may be caused by the error cause, step S602 is performed; in response to the acquired real-time position parameter being located in the past path of the movable object, the foregoing embodiment is performed to determine whether the distance between the real-time position parameter and the map position parameter is smaller than the first distance threshold, or is used as the reference position/planning endpoint, which is not limited herein.
The past path refers to a path through which the movable target has moved before, and since the target mark is used for marking the position of the movable target on the map surface, the target mark can be considered to follow the movement of the movable target, and then it can also be determined whether the real-time position parameter is located in the past movement path of the target mark.
S602: and in response to the real-time position parameter being located in the past path, temporarily storing the real-time position parameter, and keeping the target mark in the current position in the map plane.
In this embodiment, when the real-time position parameter is detected to be located on the past path for the first time, the real-time position parameter is temporarily stored, so that the target mark is kept at the current position in the map drawing, and the condition that the target mark jumps in the map drawing due to errors is reduced.
S603: sequentially acquiring a plurality of real-time parameter combinations, and judging whether each real-time position parameter is positioned on a past path or not and whether the number of the real-time position parameters positioned on the past path exceeds a preset value or not.
In this embodiment, if the number of paths in the past exceeds the preset value, it is considered that the movable object may be turning around, step S604 is performed; if the number of the paths in the past exceeds the preset value, the current flow is completed if the number is considered to be possibly caused by error reasons.
And continuously acquiring a plurality of real-time parameter combinations, and sequentially judging whether each real-time position parameter is positioned on a past path. For example, the number of real-time parameter combinations acquired in this step may be one, two, three, four, five, etc.; the frequency of acquiring the real-time parameter combination may be at intervals of a preset duration, or may be at intervals of a time shorter than the preset duration.
And judging whether the number of the paths in which the real-time position parameters are located exceeds a preset value. Alternatively, the preset value may be a number value less than the number of acquired real-time parameter combinations, may be a number value equal to the number of acquired real-time parameter combinations, or may be a certain percentage of the number value of the number of acquired real-time parameter combinations.
For example, from the first detection that the real-time location parameter is located in the past path, five real-time parameter combinations are acquired again, and then the total number of acquired real-time parameter combinations is six. If the preset value is set to be four, if no less than four real-time position parameters exist in the six real-time position parameters and are located on the past path, the movable target is considered to possibly turn around.
S604: in response to the plurality of real-time parameter combinations being located in the past path, the control target identifier moves on the map surface in accordance with the real-time position parameters.
In this embodiment, in response to the plurality of real-time parameter combinations being located on the past path, it is considered that the movable object may be turning around, and the control object identifier is moved on the map surface according to the real-time position parameters. The target mark can be directly controlled to move along with the real-time position parameter, or the target mark can be controlled to move by using the display method of the map surface in the embodiment so as to reduce the risk of jumping of the target mark.
The data storage method of the present application is exemplified below. Referring to fig. 7, fig. 7 is a flowchart illustrating an embodiment of a data storage method according to the present application.
