Problems solved by technology

[0004] At present, people establish the logical relationship between the area surface and the point of interest through manual labeling. However, after the logical relationship between the area surface and the point of interest is established, only the area surface related to the point of interest can be displayed on the electronic map. Shape features cannot accurately display the scope of the building, let alone accurately describe the area size of the building

Embodiment 1

[0086] Embodiment 1 The general process of establishing the logical relationship between POIs and buildings

[0087] figure 1 It is a schematic flowchart showing a method for establishing a logical relationship between a point of interest and a building according to an embodiment of the present invention. Such as figure 1 As shown, according to an embodiment of the present invention, first in step S101, a building and a point of interest associated with the building are acquired, wherein the description information of the building includes shape information and geographic information of the building, and the point of interest The descriptive information includes the name and geographic coordinates of the POI. Wherein, the geographic information of the building refers to the geographic coordinates or address of the building, and the address refers to a spatial address or a communication address.

[0088] Buildings and points of interest can be obtained from the user terminal...

Embodiment 2

[0093] Embodiment 2 Based on the shape information of the building and the description information of the point of interest, a logical relationship between the point of interest and the building is established

[0094] figure 2 is a schematic flow chart according to a specific embodiment of the present invention, Figure 3A and 3B based on figure 2 A schematic diagram of the user terminal interface during use of the embodiment. For clarity, only the figure 2 The example shown with the figure 1 Differences from the examples shown.

[0095] Such as figure 2 As shown, first in step S201a, a specified area surface is obtained. Here, the area plane can be obtained by methods known in the art such as keyword search method or box search method. Such as Figure 3A As shown, specify the area surrounded by the quadrilateral composed of arrows on the user interface "Zhixueyuan".

[0096] Then, in step S201b, at least a part of the POIs and buildings of the specified categor...

Embodiment 3

[0101] Embodiment 3 Based on the logical relationship between the known area surface and the interest point, the logical relationship between the interest point and the building is established

[0102] Figure 4 is a schematic flow chart according to yet another embodiment of the present invention; Figure 5A and 5B based on Figure 4 A schematic diagram of the user terminal interface during use of the embodiment. exist Figure 4In the illustrated embodiment, a logical relationship has been established between the specified area plane and the point of interest. In particular, there are a limited number of points of interest that the user is interested in in the specified area plane, for example, there is only one user interested in the specified area plane. points of interest. Generally, the specified area plane is an area plane of a cell-type POI, and this area plane is usually artificially created, and a mapping relationship with the POI has already been established. I...

Abstract

The invention relates to a method for establishing a logical relationship between an interested point and a building. The method comprises a building and interested point obtaining step for obtaining the building and the interested point associated with the building, wherein description information of the building comprises shape information and geographic coordinates of the building, and description information of the interested point comprises the name and geographic coordinates of the interested point; and a mapping establishing step for establishing a logical mapping between the associated building shape information and the interested point. According to other aspects of the invention, the invention also relates to an apparatus for establishing a logical relationship between an interested point and a building, a server and a computer readable medium. Through the method, apparatus, server and computer readable medium according to embodiments of the invention, the actual shape of the interested point of the building type can be accurately described, the geographic coordinates of the interested point can be intensively described, and human cost can be largely saved.

Description

technical field [0001] The invention relates to the technical field of digital maps, in particular to a method, device and server for establishing logical relationships between points of interest and buildings. Background technique [0002] Electronic map, that is, digital map, is a visualized map that is digitally stored and consulted using computer technology and based on digital mapping technology. "Visualization on the user terminal screen" is the fundamental feature of electronic map. [0003] On the electronic map, some geographical objects, especially some geographical entities closely related to people's lives, such as schools, banks, restaurants, gas stations, hospitals, supermarkets, etc., are abstracted into points called points of interest. The main purpose of POI is to describe the address of things or events, which can greatly enhance the ability to describe and query the location of things or events, and improve the accuracy and speed of geographic positioning...
