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. 1 is a flowchart illustrating a zooming method of an electronic map, which is performed by a terminal in which the electronic map is installed, according to an exemplary embodiment, and the zooming method of the electronic map, as illustrated in fig. 1, includes the following steps.
In step S101, it is determined that at least two spots on the electronic map are enlarged.
In one implementation mode, when it is detected that a user searches for at least two terminals logged in to the same account on an electronic map, the location where the at least two terminals on the electronic map are located is determined to be amplified. For example, a mobile phone and a tablet computer of a user log in the same account, and the user needs to search the location of the mobile phone and the tablet computer on a map, so that the user can input the same account on the electronic map for searching, and the user wants to display the location of the mobile phone and the tablet computer on the electronic map at the same time.
In another implementation, at least two search places input by a user in a local zoom search bar are received, and the at least two search places are determined to be enlarged. In this embodiment, the electronic map can provide a local zoom function, where the local zoom function means that only a certain area on the electronic map can be zoomed, and other areas are not zoomed, or other areas are zoomed at a different zoom ratio from the area. The local zoom function is mainly to simultaneously display detailed information of at least two places that are distant from each other on the electronic map.
In step S102, regions to be enlarged corresponding to at least two locations are determined, where the region to be enlarged corresponding to each location includes the location corresponding to the region to be enlarged.
In this embodiment, the to-be-amplified region corresponding to each location includes the location, for example, the location input by the user is an a cell, and the to-be-amplified region corresponding to the a cell may be a street where the a cell is located, or may be a region of 1 km or 2 km around the a cell.
In one implementation, each location is used as a central coordinate, and a region to be enlarged corresponding to each location is determined according to a preset determination rule.
In another implementation manner, a user determines a region to be magnified corresponding to each location, the user can draw a graph containing each location on an electronic map, and the terminal determines the region where the graph containing each location is located as the region to be magnified corresponding to each location.
In another implementation manner, the terminal pops up an enlargement frame containing each place on the electronic map, and determines that the enlargement frame is determined as an area to be enlarged corresponding to each place.
In step S103, the areas to be enlarged corresponding to the at least two locations are enlarged at a first scaling rate, and other areas except the areas to be enlarged corresponding to the at least two locations in the electronic map are enlarged at a second scaling rate, where the first scaling rate is smaller than the second scaling rate.
In this embodiment, the whole electronic map is not zoomed at the same zoom scale, but the to-be-zoomed regions corresponding to the at least two locations are zoomed at the first zoom scale, and the other regions except the to-be-zoomed regions corresponding to the at least two locations in the electronic map are zoomed in or zoomed out at the second zoom scale. The first zoom scale is smaller than the second zoom scale, and for the electronic map, the smaller the zoom scale, the closer the zoomed map is to the actual map, and the more detailed the map is seen by the user. The areas to be zoomed corresponding to the at least two places amplified by the first scale usually need to be capable of distinguishing streets with many places and surrounding environments of a user, the second scaling can be adjusted according to the size of a terminal screen, if the screen is large, other areas can be amplified, and if the screen is small, other areas can be not scaled, and other areas can also be reduced.
The method of the embodiment is particularly suitable for two places far away from each other, and if two places are to be displayed in the screen of the terminal at the same time in the prior art, a large scaling ratio is required, and the detailed information of the two places cannot be displayed due to the large scaling ratio. By the method of the embodiment, the areas where the two places are located can be enlarged by adopting a smaller scaling ratio, so that the user can simultaneously zoom the detailed information of the two places, and other areas which are not concerned by the user are zoomed by a larger scaling ratio.
In this embodiment, at least two places on the electronic map are determined to be enlarged, regions to be enlarged corresponding to the at least two places are determined, the regions to be enlarged corresponding to the at least two places are enlarged at a first scaling, and other regions in the electronic map except the regions to be enlarged corresponding to the at least two places are enlarged at a second scaling, where the first scaling is smaller than the second scaling. The method can zoom the same electronic map by using different zoom ratios, can zoom the places concerned by the user by using a smaller zoom ratio, and can zoom other areas in the electronic map by using a larger zoom ratio, so that the user can simultaneously see detailed information of two places with longer distances on the electronic map, and the user experience is greatly improved.
Fig. 2 is a flowchart illustrating a zooming method of an electronic map according to an exemplary embodiment, and as shown in fig. 2, the zooming method of the electronic map includes the following steps.
In step S201, when it is detected that the user searches for at least two terminals logged in the same account on the electronic map, it is determined to zoom in on the location where the at least two terminals on the electronic map are located.
In step S202, the area to be enlarged corresponding to each location is determined according to a preset determination rule with each location as a center coordinate.
The preset determination rule is, for example, coordinates with each location as a center to form a rectangular region to be magnified, which is X meters long and Y meters wide. Or, a circular area to be enlarged with the radius of M meters is formed by taking each place as a central coordinate. Or, forming a region to be enlarged along the shape of the street where the place is located with each place as a center coordinate. Here, the description is only an example, and the region to be enlarged corresponding to each location may also be determined in other manners as long as the determined region to be enlarged includes the location.
In step S203, the areas to be enlarged corresponding to the at least two locations are enlarged at a first scaling rate, and other areas except the areas to be enlarged corresponding to the at least two locations in the electronic map are enlarged at a second scaling rate, where the first scaling rate is smaller than the second scaling rate.
In this embodiment, when it is detected that a user searches for at least two terminals logged in to the same account on an electronic map, it is determined to amplify locations where the at least two terminals on the electronic map are located, then, with each location as a center coordinate, a region to be amplified corresponding to each location is determined according to a preset determination rule, the regions to be amplified corresponding to the at least two locations are amplified at a first scaling, and other regions in the electronic map except for the regions to be amplified corresponding to the at least two locations are scaled at a second scaling, where the first scaling is smaller than the second scaling. The method can zoom the places where the at least two terminals concerned by the user are located at a smaller zoom ratio, and zoom other areas in the electronic map at a larger zoom ratio, so that the user can see detailed information of the places where the at least two terminals are located on the electronic map at the same time, and user experience is greatly improved.
Fig. 3 is a flowchart illustrating a zooming method of an electronic map according to an exemplary embodiment, which includes the following steps, as shown in fig. 3.
In step S301, at least two search places input by a user in a locally zoomed search bar are received.
A local zoom option is set on the electronic map, a user opens a local zoom search bar by clicking the local zoom option, and then at least two search places needing to be searched are input in the local zoom search bar.
In step S302, it is determined that at least two search places are enlarged.
In step S303, a graphic containing each place drawn on the electronic map by the user is detected.
After a user inputs a search place, the user is prompted to draw an area to be magnified on the electronic map, and the electronic map is generally applied to an intelligent device with a touch screen, so that for each place, the user can draw a rectangle, a circle and the like on the electronic map by fingers and the shape of the place is included. If the electronic map is applied to a computer, a shape containing each location can be drawn by a mouse.
In step S304, the region where the graph including each location is located is determined as the region to be enlarged corresponding to each location.
It should be noted that, if the area to be enlarged is too large, the detailed information of at least two places cannot be displayed in the screen of the terminal at the same time after the area to be enlarged is enlarged by the first scaling, so that the terminal can also automatically adjust the shape drawn by the user to adjust the area to be enlarged to an appropriate size.
In step S305, the area to be enlarged corresponding to the at least two locations is enlarged at a first scaling rate, and the other areas except the area to be enlarged corresponding to the at least two locations in the electronic map are enlarged at a second scaling rate, where the first scaling rate is smaller than the second scaling rate.
In this embodiment, at least two search places input by a user in a local zoom search bar are received, it is determined to zoom in the at least two search places, then a graph drawn by the user on an electronic map and including each place is detected, an area where the graph including each place is located is determined as an area to be zoomed corresponding to each place, the area to be zoomed corresponding to the at least two places is zoomed at a first zoom ratio, and other areas except the area to be zoomed corresponding to the at least two places in the electronic map are zoomed at a second zoom ratio, where the first zoom ratio is smaller than the second zoom ratio. The method can zoom at least two search places concerned by the user with a smaller zoom scale, and zoom other areas in the electronic map with a larger zoom scale, so that the user can see the detailed information of the at least two search places on the electronic map at the same time, and the user experience is greatly improved.
Fig. 4 is a flowchart illustrating a zooming method of an electronic map, according to an exemplary embodiment, as shown in fig. 4, the zooming method of the electronic map includes the following steps.
In step S401, at least two search places input by the user in the locally zoomed search bar are received.
In step S402, it is determined that at least two search places are enlarged.
In step S403, an enlargement box containing each spot is popped up on the electronic map.
In step S404, the enlargement frame is determined as the region to be enlarged corresponding to each location.
And after seeing the amplifying frame, the user clicks a search button, and the terminal determines the amplifying frame as the area to be amplified corresponding to each place. Optionally, the user may also adjust the position and size of the zoom-in frame, and click a search button after adjusting to a suitable size and position, and the terminal determines that the adjusted zoom-in frame is the region to be zoomed in corresponding to each location.
In step S405, the areas to be enlarged corresponding to the at least two locations are enlarged at a first scaling rate, and other areas except the areas to be enlarged corresponding to the at least two locations in the electronic map are enlarged at a second scaling rate, where the first scaling rate is smaller than the second scaling rate.
In this embodiment, at least two search places input by a user in a local zoom search bar are received, it is determined to zoom in the at least two search places, then an enlargement frame including each place pops up on an electronic map, it is determined that the enlargement frame is a region to be enlarged corresponding to each place, the region to be enlarged corresponding to the at least two places is enlarged at a first zoom ratio, and other regions except the region to be enlarged corresponding to the at least two places in the electronic map are zoomed at a second zoom ratio, where the first zoom ratio is smaller than the second zoom ratio. The method can zoom at least two search places concerned by the user with a smaller zoom scale, and zoom other areas in the electronic map with a larger zoom scale, so that the user can see the detailed information of the at least two search places on the electronic map at the same time, and the user experience is greatly improved.
