Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are some embodiments of the present application, but not all 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 application.
Fig. 1 is a schematic view of an application scenario of a map display method according to an embodiment of the present application. As shown in fig. 1, the application scenario of the map display method includes: the display device 10, the display interface 101 of the display device 10 can be used for displaying an electronic map and elements to be displayed which can be dynamically displayed on the electronic map and are used for explaining the characteristics of the electronic map.
Optionally, the element to be displayed in the embodiment of the present application may be used to display or annotate information that is not available on the electronic map or that is dynamically refreshed. For example, the elements to be displayed may include a mark element and a line element in addition to the map element.
The map elements are inherent elements in the electronic map, and may include: buildings, parks, fields, bodies of water, road sections, driveways, and the like. The marking elements in the application can be trolleys, bubbles and the like of taxi taking software, and the line elements can comprise running routes, the longitude and latitude of each element and the like.
For example, the elements to be displayed may represent vehicles by car icons, may represent position changes of mobile terminals or vehicles on an electronic map by routes, and may explain movement information of some terminals or vehicles in the electronic map by bubbles or text boxes. Therefore, the elements to be displayed dynamically displayed on the electronic map can be used for displaying information such as vehicle travel progress, target vehicle position and the like, when a certain specific position or place is marked as a boarding point and a target destination, detailed information such as distance, estimated arrival time and the like can be displayed in the form of bubbles or text boxes, and detailed information of vehicles such as license plate numbers, vehicle colors, vehicle brands and the like can also be displayed below the corresponding area of the electronic map on the display interface.
Further, the element to be displayed may dynamically display information on the electronic map, for example, when the position of the positioning vehicle changes, the optimal scaling and position may be recalculated centering on the latest position of the vehicle, and the display information on the display interface may be refreshed. Optionally, the display of the to-be-displayed element and the map element on the electronic map may be periodically refreshed, may also be refreshed in real time, and may also be refreshed when the position change of the to-be-displayed element on the electronic map exceeds a preset range.
It can be understood that the element to be displayed is not an element of the electronic map itself or the electronic map itself, but an additional element with a specific function definition or meaning that needs to be displayed on the electronic map, the element to be displayed has a corresponding geographic position (or a corresponding position on the electronic map), and the zoom scale and the center point of the electronic map on the display interface can be determined according to the corresponding positions of all the elements to be displayed on the electronic map.
The specific type of the elements to be displayed, the specific content included in each type of elements, and the specific beneficial effect of each type of elements are not limited in the embodiments of the present application, and may be determined according to actual situations.
By way of example, fig. 1 shows an exemplary travel path 12 of a vehicle 11 in the marking element when it travels from a location a to a location B. Since the scaling and display center point of the electronic map is determined by the position of the center point of the cart on the electronic map in the prior art, the center point of the cart may be exactly located at the boundary of the display interface when the cart is displayed on the display interface 101. Because the trolley is a vehicle type mark with a certain length and width, when the central point of the trolley is probably just positioned at the boundary of the display interface 101, the body of the trolley is probably beyond the visual range of the display interface 101, namely the problem that the body of the trolley is incompletely displayed on the display interface can occur.
In view of the foregoing problems in the prior art, an embodiment of the present application provides a map display method, which may first determine a target calculation area for calculating a map zoom scale in a display interface according to a corresponding position of an element to be displayed on an electronic map and a size of the display interface, then determine an optimal zoom scale and an optimal zoom point when the electronic map is displayed on the target calculation area, and finally control display of the element to be displayed on the display interface according to the optimal zoom scale and the optimal zoom point. According to the technical scheme, the target calculation area used for calculating the map scaling on the display interface is adjusted, and a part of space is reserved on the boundary of the display interface to adapt to the display of the element to be displayed, so that the problem of incomplete display of the element to be displayed is avoided, and the user experience is improved.
The technical solution of the present application will be described in detail below with reference to specific examples. It should be noted that the following specific embodiments may be combined with each other, and the same or similar concepts or processes may not be described in detail in some embodiments.
Fig. 2 is a schematic flowchart of a first embodiment of a map display method according to an embodiment of the present application. As shown in fig. 2, the map display method according to the embodiment of the present application may include the following steps:
step 21: and acquiring the elements to be displayed on the display interface.
The element to be displayed is used for displaying or annotating information which is not or dynamically refreshed on the electronic map.
Optionally, in an embodiment of the present application, when a user performs a certain operation related to map display through a client of a terminal device, the map engine server may obtain an element to be displayed, which needs to be displayed on a display interface, according to the operation of the user.
For example, when a user calls a car and receives an order through a taxi taking client on the terminal device, the elements to be displayed in the embodiment may be a trolley, relevant information of the trolley, route information corresponding to the order, and the like. The starting position and the ending position of the trolley and the running route can be called as mark elements, and the running route of the order and the longitude and latitude of the trolley on the electronic map can be called as line elements. Therefore, the map engine server can acquire the trolley and the relevant information of the trolley which are required to be displayed on the display interface, the route information corresponding to the order and the like according to the order information.
Step 22: and determining a target calculation area for calculating the map scaling on the display interface according to the corresponding position of the element to be displayed on the electronic map and the size of the display interface.
In the embodiment of the application, the map engine server may analyze whether the element to be displayed can be completely displayed on the display interface according to distribution information of the element to be displayed on the electronic map, that is, a corresponding position of the element to be displayed on the electronic map, and then, in combination with the size of the display interface, may adjust the size of a target calculation area for calculating a map scaling on the display interface according to a positional relationship between the part of the element to be displayed which is incompletely displayed and the display interface, so that when the electronic map is displayed in the target calculation area, all elements in the element to be displayed can be completely displayed on the display interface.
It should be noted that, when the target calculation area is used to calculate the zoom level of the map, and the calculated zoom level is used to control the elements to be displayed on the display interface, all the elements to be displayed can be completely displayed on the display interface.
Optionally, for a specific implementation of this step 22, reference may be made to the following description in the embodiment shown in fig. 3, which is not described herein again.
Step 23: and determining the optimal scaling and the optimal central point of the electronic map when the electronic map is displayed on the target calculation area according to the corresponding position of the element to be displayed on the electronic map and the size of the target calculation area.
Optionally, in an embodiment of the present application, after a target calculation area that can be used for calculating a map zoom ratio on a display interface is determined, the map engine server may determine, according to a corresponding position of the to-be-displayed element on the electronic map and when the to-be-displayed element and the electronic map are displayed in the target calculation area, whether both the to-be-displayed element and the electronic map can be completely and symmetrically displayed in a centered manner, and use a map zoom ratio and a center point when the to-be-displayed element and the electronic map can be completely and symmetrically displayed in a centered manner as an optimal zoom ratio and an optimal center point.
Optionally, for a specific implementation of this step 23, reference may be made to the following description in the embodiment shown in fig. 4, which is not described herein again.
Step 24: and controlling the element to be displayed on the display interface according to the optimal scaling and the optimal central point.
In the embodiment of the application, the optimal zoom scale can enable the element to be displayed and the electronic map to be displayed completely on the display interface, and the optimal central point can enable the element to be displayed and the electronic map to be displayed symmetrically centered on the display interface.
According to the map display method provided by the embodiment of the application, the element to be displayed on the display interface is obtained, the target calculation area used for calculating the map scaling on the display interface is determined according to the corresponding position of the element to be displayed on the electronic map and the size of the display interface, the optimal scaling and the optimal center point of the electronic map on the target calculation area are determined according to the corresponding position of the element to be displayed on the electronic map and the size of the target calculation area, and finally the element to be displayed is controlled to be displayed on the display interface according to the optimal scaling and the optimal center point. According to the technical scheme, the electronic map and the elements to be displayed can be displayed completely on the display interface, and user experience is improved.
Optionally, on the basis of the foregoing embodiment, fig. 3 is a schematic flow chart of a second embodiment of a map display method provided in the embodiment of the present application. As shown in fig. 3, in an embodiment of the present application, the step 22 (determining a target calculation area for calculating a map scaling on the display interface according to the corresponding position of the element to be displayed on the electronic map and the size of the display interface) may include the following steps:
step 31: and determining a first scaling and a first central point of the electronic map when the electronic map is displayed on the display interface according to the corresponding positions of the central points of all the elements to be displayed on the electronic map and the size of the display interface.
Optionally, in an embodiment of the application, after obtaining all the elements corresponding to the elements to be displayed, the map engine server may first determine a corresponding position of a center point of each element on the electronic map, and when the center points of all the elements can be displayed on the display interface, by performing scaling operation, when the electronic map is displayed on the display interface, a first scaling and a first center point of the electronic map may be determined.
It can be understood that the first scaling and the first center point in this embodiment are calculated by using the corresponding positions of the center points of all the elements in the to-be-displayed elements and the size of the display interface, and if the to-be-displayed elements are all displayed on the display interface in the form of points, the view effect of the electronic map on the display interface is the best.
Step 32: and when all the elements in the elements to be displayed are controlled to be displayed on the display interface at the first scaling and the first central point, judging whether all the elements in the elements to be displayed can be completely displayed on the display interface.
Optionally, in an embodiment of the present application, when the element to be displayed is controlled to be displayed on the display interface at the first zoom scale and the first center point, the element to be displayed is usually displayed in a set actual shape on the display interface, for example, the route is displayed on the display interface in the form of a running route, and the cart is displayed and moved on the map in the shape of a car.
Generally, an element representing a specific meaning or function usually has a physical shape larger than an area occupied by one dot. For example, when a cart representing a vehicle is displayed on the display interface, the area actually occupied by the cart is much larger than the area occupied by the center point of the cart, and therefore, if the marker elements such as the cart are displayed on the display interface at the calculated first zoom ratio and the first center point, a phenomenon that a partial area of the cart is not within the visual range of the user may occur, that is, the cart display is incomplete. Therefore, in this embodiment, when the to-be-displayed elements are displayed on the display interface at the first zoom ratio and the first center point, it is necessary to determine whether all the elements in the to-be-displayed elements can be completely displayed when displayed on the display interface, and if part of the elements in the to-be-displayed elements are incompletely displayed, the target calculation area for calculating the map zoom ratio on the display interface is adjusted.
Step 33: and if partial elements exist in the elements to be displayed and cannot be completely displayed on the display interface, determining the maximum length of the part, which is not displayed, in the partial elements.
Optionally, in this embodiment, through the judgment in the step 32, when it is determined that some of the elements to be displayed cannot be completely displayed on the display interface, the maximum length of the part, which is not displayed, of all the elements that are not completely displayed, that is, the maximum length of the element that is not completely displayed, that exceeds the boundary of the display interface, may be respectively calculated.
It should be noted that, in this step, the length of the non-displayed part of the partial element may be understood as the length of the partial element exceeding (extending) the length of the display interface when the partial element is completely displayed, and thus, the maximum length of the non-displayed part of the partial element refers to the value of the maximum distance from the display interface boundary in the element part exceeding the display interface boundary.
Step 34: and determining a target calculation area for calculating the map scaling on the display interface according to the maximum length and the size of the display interface.
Optionally, in an embodiment of the present application, in order to enable all elements in the elements to be displayed to be completely displayed on the display interface, partial spaces may be respectively reserved on four boundaries of the display interface to adaptively display an undisplayed part of the partial elements.
As an example, this step 34 can be implemented by:
step A1: and taking the maximum length of the part which is not displayed in the part elements as the width of the reserved area required by each boundary of the display interface.
Step A2: acquiring a residual area of the display interface after subtracting the required reserved area from each boundary;
step A3: and taking the rest area of the display interface as a target calculation area for calculating the map scaling on the display interface.
Optionally, when the maximum length of the undisplayed part in the incomplete element to be displayed is determined, the calculated maximum length may be used as a space required to be reserved for each boundary of the display interface, and then the spaces required to be reserved are subtracted from the four boundaries of the display interface, where the remaining area is the remaining area of the display interface. In this embodiment, the remaining area of the display interface may be used as a target calculation area for calculating the map zoom scale on the display interface.
The map display method provided by the embodiment of the application comprises the steps of firstly determining a first scaling and a first central point when an electronic map is displayed on a display interface according to corresponding positions of the central points of all elements in the elements to be displayed on the electronic map and the size of the display interface, secondly controlling all elements in the elements to be displayed on the display interface according to the first scaling and the first central point, judging whether all elements in the elements to be displayed can be completely displayed on the display interface, if part of the elements to be displayed cannot be completely displayed on the display interface, determining the maximum length of an undisplayed part in the part of the elements, and finally determining a target calculation area for calculating the scaling of the map on the display interface according to the maximum length and the size of the display interface. The technical scheme determines the target calculation area for calculating the map scaling on the display interface, and provides a realization possibility for the complete display of the subsequent elements to be displayed on the display interface.
Optionally, on the basis of the foregoing embodiment, fig. 4 is a schematic flowchart of a third embodiment of a map display method provided in the embodiment of the present application. As shown in fig. 4, in an embodiment of the present application, the step 23 (determining an optimal zoom ratio and an optimal center point when the electronic map is displayed on the target calculation area according to the corresponding position of the element to be displayed on the electronic map and the size of the target calculation area) may include the following steps:
step 41: and determining a second scaling and a second central point when the electronic map is displayed on the target calculation area according to the corresponding positions of the central points of all the elements to be displayed on the electronic map and the size of the target calculation area.
Optionally, since the size of the target calculation area determined in the above embodiment is different from that of the display interface, that is, the area available for calculating the map zoom ratio on the display interface is changed, in order to enable the electronic map to have the best view effect when displayed on the display interface, the map engine server needs to recalculate the second zoom ratio and the second center point when the electronic map is displayed on the target calculation area after determining the target calculation area used for calculating the map zoom ratio.
In this embodiment, since this step is different from the size of the area for calculating the first zoom ratio and the first center point in step 31 described above, the values of the second zoom ratio and the first zoom ratio are different, and since the target calculation area is the same as the center point of the display interface, the coordinates of the second center point and the first center point are the same.
Step 42: and when all the elements in the elements to be displayed are controlled to be displayed on the display interface at the second scaling and the second central point, determining the longitude and latitude where the boundaries of all the elements in the elements to be displayed are located.
Optionally, in this embodiment, after the second zoom scale and the second center point when the electronic map is displayed on the target computing area are determined, the electronic map and the to-be-displayed elements may be controlled to be displayed on the display interface at the second zoom scale and the second center point, and the longitude and latitude where the boundaries of all the elements in the to-be-displayed elements are located are recorded. Therefore, the latitude and longitude of all the elements to be displayed (such as the trolley) when the corners are displayed at the second scaling can be obtained through the step.
Step 43: and updating the second central point according to the longitude and latitude of the boundary of all the elements to be displayed.
The second scaling is the optimal scaling, and the updated second center point is the optimal center point.
Optionally, as can be seen from the above analysis, the maximum length of the undisplayed part of the undisplayed complete partial elements is around the boundary of the target calculation area on the display interface, and due to the different lengths of the undisplayed parts of the different elements, when the to-be-displayed element and the electronic map are displayed on the display interface, the electronic map may not be displayed in the middle, that is, when the to-be-displayed element and the electronic map are controlled to be displayed on the display interface with the second central point as the center, the visual effect is poor. For the problem, in this embodiment, the longitude and latitude of the boundaries of all the elements to be displayed may be integrated, the target calculation area is translated on the display interface until the view effect of the elements to be displayed and the electronic map on the display interface is optimal, and the central point of the target calculation area at this time is recorded, so that the second central point is updated by using the central point.
In this embodiment, when the element to be displayed and the electronic map are controlled to be displayed on the display interface at the second zoom ratio and the updated second center point, the visual effect of the display interface is optimal, so that the second zoom ratio can be used as the optimal zoom ratio, and the updated second center point can be used as the optimal center point.
According to the map display method provided by the embodiment of the application, the second scaling and the second central point of the electronic map when the electronic map is displayed on the target calculation area are determined according to the corresponding positions of the central points of all the elements to be displayed on the electronic map and the size of the target calculation area, the longitude and latitude where the boundaries of all the elements to be displayed are located are determined when all the elements to be displayed are displayed on the display interface according to the second scaling and the second central point, finally, the second central point is updated according to the longitude and latitude where the boundaries of all the elements to be displayed are located, the second scaling is the optimal scaling, and the updated second central point is the optimal central point. According to the technical scheme, the optimal scaling and the optimal central point of the target calculation area are re-determined, so that complete display of the elements to be displayed and the electronic map is achieved, the obtained visual display effect is optimal, and the visual experience of a user is good.
Optionally, the following embodiments exemplify an example in which a mark element in the elements to be displayed is not completely displayed on the display interface.

Step 52: and calculating a first scaling and a first central point of the electronic map when the electronic map is displayed on the display interface according to the corresponding positions of the central points of all the elements to be displayed on the electronic map and the size of the display interface.
Step 53: and classifying all the elements to be displayed according to the characteristics of each element to be displayed to obtain mark elements and line elements.
Alternatively, the element to be displayed for marking an object or for interpreting certain information may be referred to as a marking element, e.g. a trolley in the taxi-taking software, a bubble for interpreting travel route information, depending on the function and definition of the element to be displayed. Accordingly, the running route of the vehicle and the latitude and longitude where the element to be displayed is located may be referred to as a line element.
Step 54: and when the situation that the elements to be displayed of the mark class cannot be completely displayed on the display interface is determined, calculating the size of the part which is not displayed, and acquiring the maximum length of the part which is not displayed.
Optionally, the mark-like element to be displayed cannot be displayed completely on the display interface, and it can be considered that when the element to be displayed is displayed on the display interface, some of the elements are not within the user's sight line range, at this time, the length of the non-displayed part which is not within the user's sight line range can be calculated, and the maximum length among the lengths of all the non-displayed parts can be determined.
Step 55: and respectively subtracting the maximum length of the non-displayed part from each boundary of the display interface to obtain a target calculation area for calculating the map scaling in the display interface.
Step 56: and calculating a second scaling and a second central point of the electronic map when the electronic map is displayed on the target calculation area according to the central points of all the elements to be displayed and the size of the target calculation area.
Optionally, in this embodiment of the present application, since the sizes of the areas participating in the calculation in step 52 and step 56 are different, the second scaling calculated in this step is different from the first scaling calculated in the above step, and since the maximum length of the non-displayed portion is subtracted from each boundary of the display interface, the second center point calculated in this step is the same as the first center point calculated in step 52. When all the elements to be displayed are displayed in the target calculation area by the second scaling and the second central point, although all the elements to be displayed are located in the display interface, a part of the part with a small length which is not displayed is spaced from the boundary of the display interface and is not symmetrical in the middle, so that the central point needs to be recalculated, and the map area corresponding to the elements to be displayed is shifted.
And 57: and calculating the longitude and latitude of each corner of all the elements to be displayed on the basis of the second scaling.
Step 58: and updating the second central point by utilizing the longitude and latitude of each corner of all the elements to be displayed.
Step 59: and displaying all the elements to be displayed and the electronic map on the display interface at a second zoom scale and the updated second central point.
