Embodiment 1

[0062] figure 2It is a flow chart of a method for displaying a point of interest provided in Embodiment 1 of the present invention. This embodiment is applicable to the case of displaying building-type points of interest, and the method may be executed by a device for displaying points of interest, and the device may be implemented by means of software and / or hardware. see figure 2 , a method for displaying a point of interest provided in this embodiment includes:

[0063] S110. Obtain a target point of interest.

[0064] Specifically, the point of interest input by the user through the search box can be used as the target point of interest to obtain the target point of interest; it can also be the point of interest to be displayed that falls within the range of the terminal display screen in the electronic map displayed with the set display scale point as the target POI to obtain the target POI. Other acquisition methods are also possible, which is not limited in this e...

Embodiment 2

[0100] image 3 It is a flow chart of a method for displaying points of interest provided in Embodiment 2 of the present invention. This embodiment is an optional solution proposed on the basis of the first embodiment above. see image 3 , the method for displaying points of interest provided in this embodiment includes:

[0101] S210. Determine the target POI group according to the preset affiliation relationship of the target POI.

[0102] S220. Delete isolated POIs and repeated POIs in the target POI cluster.

[0103] S230. When the number of interest points in the target interest point cluster is greater than a set threshold, determine a polygon including all interest points in the target interest point cluster based on a convex hull algorithm.

[0104] S240. When the number of interest points in the target interest point cluster is less than or equal to a set threshold, determine a minimum circumscribing rectangle according to the coordinates of the interest points, a...

Embodiment 3

[0114] Figure 9 It is a schematic structural diagram of a point-of-interest display device provided in Embodiment 3 of the present invention. see Figure 9 , a point of interest display device provided in this embodiment includes: a target acquisition module 10 , an area determination module 20 and a display module 30 .

[0115] Among them, the target acquisition module 10 is used to acquire the target interest point; the area determination module 20 is used to acquire the predetermined shape area corresponding to the building according to the target interest point, wherein according to the preset affiliation of the target interest point relation, determine the shape area of ​​the building corresponding to the target interest point; the display module 30 is configured to highlight and display the shape area of ​​the building.

[0116] The point-of-interest display device provided in the embodiments of the present invention can execute the point-of-interest display method pr...

Abstract

The invention discloses an interest point display method, device, equipment and medium, and relates to the technical field of electronic maps. The method comprises the steps that a target interest point is acquired; based on the target interest point, the shape area of a corresponding building determined in advance is acquired, and based on the preset subordination relation of the target interestpoint, the shape area of the building corresponding to the target interest point is determined; the shape area of the building is displayed in a projecting mode. By means of the interest point displaymethod, device, equipment and medium, the purpose that when the target interest point is selected, the shape area of the corresponding building is displayed is achieved.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of electronic maps, and in particular, to a method, device, device and medium for displaying points of interest. Background technique [0002] The graphics displayed in the electronic map are basically composed of points, lines and surfaces. As an important part of point data, interest points are an indispensable part of the electronic map; theoretically, any buildings, regions and points of specific significance that can be named can be Displayed as point of interest data, such as Tiananmen Square, a restaurant, community, parking lot, bus station, etc. [0003] see figure 1 , currently in the electronic map, there is an attachment relationship between the point of interest 100 and the preset area surface 101 , and when the target point of interest 100 is selected, the area surface 101 attached to it is also highlighted and displayed accordingly. Among them, the articulated relations...
