Embodiment 1

[0058] see figure 2 , is a flowchart of a POI labeling method provided by the present invention.

[0059] The POI labeling method provided in this embodiment includes the following steps:

[0060] Step S11: Determine the POI to be marked in the screen.

[0061] In the embodiment of the present invention, the specific implementation of step S11 can be as follows: according to the current position of the terminal, the screen size and the scale of the electronic map, determine the latitude and longitude range corresponding to the screen, and determine from the database used to store POI data that the latitude and longitude coordinates fall within POIs within the latitude and longitude range are determined as POIs to be marked on the screen.

[0062] Step S12: traverse each POI to be marked, and perform the following steps on the traversed POI to be marked:

[0063] Step S121: Generate a display range corresponding to the POI to be marked, and the display range includes an ico...

Embodiment 2

[0092] In the first embodiment, the POI to be marked and the marked object are judged on the importance level and overlap one by one, but in this embodiment, the marked objects that overlap with the POI to be marked are first extracted, and then the importance level is carried out one by one and specific overlap judgments.

[0093] see Figure 7 , is a flowchart of a POI labeling method provided in Embodiment 2 of the present invention.

[0094] The POI labeling method provided in this embodiment includes the following steps:

[0095] Step S21: Determine the POI to be marked in the screen.

[0096] Step S22: traverse each POI to be marked, and perform the following steps on the traversed POI to be marked:

[0097] Step S221: Generate a display range corresponding to the POI to be marked, and the display range includes an icon display range and a text display range.

[0098] Step S222: Judging the overlap of display ranges between the POI to be marked and the marked objects i...

Embodiment 3

[0108] see Figure 8a , which is a schematic structural diagram of a POI labeling device provided by the present invention.

[0109] The POI point labeling device provided in this embodiment includes: POI determining unit 11, processing unit 12 and labeling unit 13, wherein, said processing unit 12 includes traversing subunit 121, generating subunit 122, judging subunit 123 and first processing Subunit 124;

[0110] The POI determination unit 11 is connected to the processing unit 12, and the processing unit 12 is connected to the labeling unit 13; the traversal subunit 121 is connected to the generation subunit 122, and the generation subunit 122 is connected to the generation subunit 122. The first processing subunit 124 in the judgment subunit 123 is connected;

[0111] The POI determination unit 11 is configured to determine the POI to be marked in the screen;

[0112] The traversal subunit 121 is configured to traverse each POI to be marked, and trigger the generation ...

Abstract

The invention discloses a POI labeling method and device. The method comprises the following steps of: determining to-be-labelled POIs in a screen; traversing each to-be-labelled POI; executing the following step on the traversed to-be-labelled POIs: generating display ranges corresponding to the to-be-labelled POIs; carrying out important grade and display range superposition judgement on the to-be-labelled POIs and a label object in a storage unit; when the judging result indicates that the important grades of the to-be-labelled POIs are lower than or equal to that of the label object, if the icon display ranges of the to-be-labelled POIs are not superposed with a display range of the label object and the character display ranges of the to-be-labelled POIs are superposed with the display range of the label object, deleting the character display ranges of the to-be-labelled POIs, and continuing to carry out important grade and display range superposition judgement on the to-be-labelled POIs and the next label object; and traversing all the to-be-labelled POIs, and labelling the label objects in the storage unit in the screen. According to the method and device, the screen display space utilization rate and the quantity of labelled POIs are improved.

Description

technical field [0001] The invention relates to the field of electronic maps, in particular to a POI marking method and device. Background technique [0002] With the popularity of the Internet, it is more and more common for users to use electronic maps (Electronic Maps) on terminal devices (such as mobile phones, tablet computers, etc.). Electronic map data includes POI (Point of Interest, also known as information point, point of interest, etc.), and the attribute information corresponding to POI includes latitude and longitude coordinates, name, address, type and other in-depth information (such as pictures, phone numbers, store details, etc.) . When the electronic map software installed on the terminal device receives an electronic map display instruction (such as the electronic map that needs to be displayed to the user when the user opens the electronic map software for the first time, the electronic map that needs to be displayed to the user when the user searches f...
