Embodiment 1
[0059] see figure 1 , which is a schematic flowchart of a method for switching from a two-dimensional map to a three-dimensional map provided in this embodiment, the method includes:
[0060] S101: In response to a switching request from the two-dimensional map to the three-dimensional map, change the vertical downward viewing angle corresponding to the two-dimensional map to an oblique viewing angle, and gradually increase the angle of view inclination.
[0061] In one embodiment of the present application, before step S101 is executed, a switch request from a two-dimensional map to a three-dimensional map may be triggered in the following manner, specifically: detecting a zoom operation on the two-dimensional map, when the two-dimensional map When the map is enlarged to a first preset zoom level, a switching request from the two-dimensional map to the three-dimensional map is triggered.
[0062] In this embodiment, the user can perform a zoom operation on the map display in...
Embodiment 2
[0086] see figure 2 , which is a schematic flowchart of a method for switching from a three-dimensional map to a two-dimensional map provided in this embodiment, the method includes:
[0087] S201: In response to a switching request from the three-dimensional map to the two-dimensional map, gradually change an oblique viewing angle corresponding to the three-dimensional map to a vertical downward viewing angle.
[0088] In an implementation manner of the present application, before step S201 is executed, a switch request from a three-dimensional map to a two-dimensional map may be triggered in the following manner, specifically: detecting a zoom operation on the three-dimensional map, when the three-dimensional map is When zooming out to a second preset zoom level, a switching request from the three-dimensional map to the two-dimensional map is triggered.
[0089] In this embodiment, the user can perform a zoom operation on the map display interface on the display device. Fo...
Embodiment 3
[0112] see image 3 , which is a schematic composition diagram of a device for switching from a two-dimensional map to a three-dimensional map provided in this embodiment. The device can be installed on a navigation device. The device 300 includes:
[0113] The first angle of view tilting unit 301 is configured to, in response to the switching request from the two-dimensional map to the three-dimensional map, convert the vertical downward angle of view corresponding to the two-dimensional map into an oblique angle of view, and gradually increase the angle of inclination of the angle of view ;
[0114] The first map switching unit 302 is configured to gradually increase the height of each display object in the two-dimensional map from the corresponding display position in the process of changing the viewing angle until the display object is simulated by the three-dimensional map Displayed in three-dimensional form.
[0115] In an embodiment of the present application, the dev...
