Abstract

The invention discloses a map state conversion method and device. Wherein, the method includes: displaying a map image in the current interface; detecting a state switching signal, wherein the state switching signal is used to switch the display state of the map image, and the display state includes: a spherical state or a planar state; After the signal, the switched map image is displayed, wherein the switched map image is obtained by mapping the coordinate value of each pixel in the map image. The invention solves the technical problems of high complexity and low conversion efficiency of the state conversion method of the map in the prior art.

Description

technical field [0001] The invention relates to the field of teaching applications, in particular to a map state conversion method and device. Background technique [0002] In real life, the earth is round, but the maps used in real life are flat. In the field of teaching applications, in order to dynamically show students how the earth is converted into a flat map in life, it is necessary to convert the state of the map. The conversion process of the traditional spherical map and the planar map is generally realized by calculating the vertex position of the spherical surface in the 3D (three-dimensional, full name 3Dimensions) space in real time in a certain period of time. However, the complexity of this method is high, resulting in low conversion efficiency, and it takes a long time to view the converted map. [0003] Aiming at the problems of high complexity and low conversion efficiency of the map state conversion method in the prior art, no effective solution has bee...
