Problems solved by technology

[0002] A two-dimensional map refers to a flat abstract map. When using a two-dimensional map, it is characterized by saving network resources and running faster, but it is not intuitive enough
A 3D map refers to a simulated three-dimensional map. When using a 3D map, it is characterized by being intuitive and easy to identify, but it takes up a lot of network resources and runs relatively slowly.
[0004] However, although the existing switching method between two-dimensional maps and three-dimensional maps has realized map switching, the switching effect is blunt and unnatural

Abstract

The invention discloses a method and device for switching between a two-dimensional map and a three-dimensional map. By responding to the switching request of the two-dimensional map to the three-dimensional map, a vertical downward viewing angle corresponding to the two-dimensional map is converted to a tilt viewing angle, the tilt extent of the viewing angle is gradually increased, meanwhile in the process of changing the viewing angle, each display object in the two-dimensional map starts to increase gradually from the corresponding display position, until each display object is shown as a simulation stereoscopic form of the three-dimensional map. Thus, in the map switching process, the viewing angle of the map is gradually changed, meanwhile each display object in the map grows gradually higher at the original position and gradually transits to the stereoscopic simulation form corresponding to the three-dimensional map, and the gradual transformation process of map manifestation form achieves the natural transition from the two-dimensional map to the three-dimensional map.

Description

technical field [0001] The present application relates to the field of map technology, in particular to a method and device for switching between a two-dimensional map and a three-dimensional map. Background technique [0002] A two-dimensional map refers to a flat abstract map. When using a two-dimensional map, it is characterized by saving network resources and running faster, but it is not intuitive enough. A 3D map refers to a simulated three-dimensional map. When using a 3D map, it is characterized by being intuitive and easy to identify, but it takes up a lot of network resources and runs relatively slowly. [0003] Users can switch between two-dimensional maps and three-dimensional maps according to their needs. In current electronic map applications, manual clicks are often used to switch between two-dimensional maps and three-dimensional maps. For example, when using Baidu Maps, the 2D map is first displayed; if you want to switch from the 2D map to the 3D map, the...
