Embodiment 1

[0056] refer to figure 1 , is a flow chart of a map display method provided in Embodiment 1 of the present application. The method is applied to electronic devices such as navigation devices (such as navigators, mobile terminals (such as mobile phones) installed with navigation software), and the navigation The device includes a screen for displaying an electronic map, and the display screen may be a liquid crystal display or a touch display, and the method may include the following steps:

[0057] Step 101: Obtain the current center point of the electronic map displayed on the screen of the navigation device and the target center point of the electronic map to be displayed.

[0058] Wherein, the current center point refers to the center point of the electronic map currently displayed on the screen of the navigation device, and the target center point refers to the center point of the electronic map to be displayed on the screen of the navigation device.

[0059] Taking the n...

Embodiment 2

[0067] Compared with the map display method provided in Embodiment 1, the map display method provided in Embodiment 2 of the present application has figure 1 Step 102 in the flow chart shown is refined. refer to image 3 , is a flow chart of step 102, wherein said step 102 can be specifically implemented through the following steps:

[0068] Step 121: Determine the distance between the current center point and the target center point.

[0069] Step 122: Determine whether the distance is greater than a preset distance threshold, and when the distance is greater than the distance threshold, perform step 123; otherwise, perform step 125.

[0070] Step 123: On the connection line between the current center point and the target center point, select a third center point whose distance from the current center point is equal to the distance threshold, and perform step 124.

[0071] Step 124: Taking the current center point as a starting point, select at least one intermediate point...

Embodiment 3

[0079] In practical applications, in order to improve the acquisition and coherent display rate of the electronic map corresponding to the intermediate point and the target center point, the electronic map corresponding to each intermediate point and the target center point can be pre-drawn and cached, and displayed on the screen of the navigation device. When the intermediate point and the target center point are the electronic maps of the center point, the corresponding electronic map is directly obtained from the cache and displayed on the screen of the navigation device. Compared with the foregoing embodiment one and embodiment two, the difference between this embodiment three is that figure 1 Step 103 in the flow shown is refined. Therefore, refer to Figure 5 , is a flowchart of step 103, wherein said step 103 may include the following steps:

[0080] Step 131: Obtain the map data cached when generating the electronic map with the current center point as the center poi...

Abstract

The invention discloses a map display method and device. The method includes: acquiring the current central point of an electronic map displayed on a navigation equipment screen and the target central point of a to-be-displayed electronic map; selecting at one middle point between the current central point and the target central point; displaying the to-be-displayed electronic map on the navigation equipment screen by sequentially using each middle point and the target central point as the central point and according to the distance from each middle point and the target central point to the current central point from near to far. The method has the advantages that during switching display of maps corresponding to two points, multiple points between the two points can be selected as the middle points, the electronic maps corresponding to the middle points are then sequentially displayed, coherent display of the maps of the middle points is achieved, electronic map switching is allowed to be approximate to animation coherent display, the eyes of a user do not need to refocus repeatedly to adapt to images, user visual fatigue is reduced, and user experience is improved.

Description

technical field [0001] The present application relates to the field of geographical information, in particular to a map display method and device. Background technique [0002] At present, when a user searches for an information point POI in an electronic map, multiple POI records may be found. When the user needs to view a POI, the user can click the corresponding POI record to display the POI at the center of the navigation device screen. That is, when the user clicks on a POI record, the navigation device will re-draw the electronic map on the screen with the coordinates of the POI in the POI record as the center point. This way of displaying the electronic map has the following technical problems when the distance between the two POIs before and after the user needs to view is relatively long, and they cannot be displayed on the screen of the navigation device at the same time: [0003] After the user clicks on the previous POI, the navigation device draws the electroni...
