Method and apparatus for displaying electronic map

Abstract

The invention discloses a method and apparatus for displaying an electronic map, for solving the problem that an electronic map in the prior art moves stiff so that the displaying effect of the electronic map is bad. The method comprises the steps: acquiring the three dimensional coordinates of an initial position point and a target position point in an electronic map; according to the three dimensional coordinates of the initial position point and the target position point, determining the three dimensional coordinates of key nodes; according to the three dimensional coordinates of the initial position point, the target position point and the key nodes, generating a space curve which successively connects the initial position point, the target position point and the key nodes; according to the preset map display duration, movement function and screen brushing time interval, determining the moving points in the space curve, and taking the target position point as one moving point; and taking the initial position point as the starting point, along the space curve, successively taking the moving points as the center point, and displaying the electronic map.

Description

technical field [0001] The invention relates to the technical field of image processing, in particular to a method and device for displaying an electronic map. Background technique [0002] At present, when moving an electronic map on a terminal device, the electronic map is directly displayed with the target location point as the center point. When the initial location point is far away from the target location point, the map screen of the electronic map displayed at the initial location The map screens of the electronic map displayed at the target location point are quite different, so the jump from the electronic map is relatively blunt visually. For example, if the initial location point of the electronic map is in Shanghai, and the target location point is in Beijing, then the map screen displayed at the initial location point is part of the map data of the Shanghai area, and the map screen displayed at the target location point is part of the map data of the Beijing ar...
