Detailed Description
In the following, only certain exemplary embodiments are briefly described. As those skilled in the art will recognize, the described embodiments may be modified in various different ways, all without departing from the spirit or scope of the present invention. Accordingly, the drawings and description are to be regarded as illustrative in nature, and not as restrictive.
When an electronic map is produced, descriptive information such as names, addresses and the like of buildings needs to be collected and stored in a computer storage device, and the buildings are abstracted into interest points, wherein the descriptive information of the interest points comprises information such as names, categories, geographic coordinates and the like.
Buildings are important elements in the real world and electronic maps, and have the characteristics of obvious shape, weak changeability and the like. And the interest points on the map keep the position coordinates of the building and other describable specific information, and obscure the shape characteristics of the building.
Thus, there is a need in the art to establish a logical relationship between points of interest and buildings, not only to enrich the properties of the buildings, but also to apply such logical relationship to a variety of scenarios, such as navigation, etc.
The basic idea of the embodiment of the invention is to establish a one-to-one mapping relationship between the description information of the building in the database and the corresponding interest points of the building on the electronic map according to the geographic coordinates or addresses of the building, such as the name of province and city, the name of street, the number of buildings and the like, wherein the description information of the building comprises the shape characteristics of the building.
Example 1 general procedure for establishing a logical relationship between a point of interest and a building
FIG. 1 is a schematic flow chart diagram illustrating a method of establishing a logical relationship between a point of interest and a building in accordance with one embodiment of the present invention. As shown in fig. 1, according to an embodiment of the present invention, first, in step S101, a building and a point of interest associated with the building are obtained, where description information of the building includes shape information and geographic information of the building, and description information of the point of interest includes a name and geographic coordinates of the point of interest. The geographic information of the building refers to geographic coordinates or an address of the building, and the address refers to a space address or a communication address.
The buildings and the interest points can be obtained by receiving the input of the user from a user terminal used by the user, the user can input characters and the like in a search box, double-click the characters, icons and the like on a user interface, and the like, and can also be input by voice.
The shape of the building can be obtained by image processing methods known in the art, such as boundary feature methods, fourier shape descriptors, geometric parameter methods, shape invariant moment methods, wavelet descriptors, finite element methods, rotation function methods, and the like; can also be obtained by a manual labeling method, and the like. Typically, the building description information to be obtained is stored in a building description information module or database.
Generally, description information of a point of interest is stored in a point of interest information module or database of an electronic map, and the description information of the point of interest includes a name, a category, and geographic coordinates of the point of interest.
Next, in step S102, a logical mapping between the shape information of the associated building and the interest point is established, that is, a mapping relationship is generated between the interest point associated with the building and the shape information of the building. In particular, in one variant of the present embodiment, the establishment of the logical mapping relationship between the shape information of the associated building and the points of interest is automated.
Finally, in step S103, the shape of the building mapped by the interest point association is displayed. In general, there are two types of representation methods for the shape feature of a building, one is a contour feature and the other is a region feature. The outline features of the image are primarily directed to the outer boundaries of the building, while the area features of the image relate to the entire shape area. Here, for example, an outline or an entire area of a building may be highlighted or an entire area of a building may be rendered and displayed, or the like. For example, when the interest point is retrieved on the user terminal interface, the outline of the building corresponding to the interest point is highlighted.
Embodiment 2 establishing a logical relationship between a point of interest and a building based on shape information of the building and description information of the point of interest
Fig. 2 is a schematic flow chart according to an embodiment of the present invention, and fig. 3A and 3B are schematic user terminal interfaces during use according to the embodiment of fig. 2. For clarity, only the differences between the embodiment shown in fig. 2 and the embodiment shown in fig. 1 are described herein.
As shown in fig. 2, first, in step S201a, a designated area surface is acquired. Here, the area surface may be obtained by a keyword search method, a block search method, or the like known in the art. As shown in fig. 3A, an area plane "intelligent park" surrounded by a quadrangle made up of arrows is specified on the user interface.
Then, in step S201b, at least a part of the interest points and buildings of the designated category in the designated area surface are acquired, or all of the interest points and buildings of the designated category in the designated area surface may be acquired. Here, a "sort" search may be selected in a toolbar of an electronic map, or a specified category may be input in a keyword search, or the like, geographic coordinates of a point of interest and a building of the specified category and geographic coordinates of a specified area plane are obtained, the geographic coordinates of the area plane and the geographic coordinates of the point of interest are compared, and if the geographic coordinates of the point of interest are located within a range specified by the geographic coordinates of the area plane, the point of interest is located within the area plane; and comparing the geographic coordinates of the area surface with the geographic coordinates of the building, wherein the building is positioned in the area surface if the geographic coordinates of the building are positioned in the range specified by the geographic coordinates of the area surface. For example, as shown in FIG. 3B, all building types of interest and buildings in a specified area are searched out and each building and related interest are represented by a small block diagram. Further, the buildings in the designated area surface can be displayed in different colors according to the intention of the user or the usage habit of the user, for example, if the user wants to find the teaching building in the designated area, the teaching building in the designated area surface is highlighted.
Next, in step S201c, the obtained interest points are clustered, and after the clustering is completed, related interest points representing each building are obtained. Theoretically, a building only corresponds to one interest point, the interest points representing the building are denoised, and a unique interest point representing the building is obtained, namely the interest point is the interest point associated with the building, wherein small low-rise buildings such as flat houses and the like which are unknown and have no business are generally noise.
For example, the points of interest may be clustered using K-means clustering, where the initial cluster center is selected as the geometric center of the shape of the building under the area. After clustering is completed, processing, particularly denoising processing, is carried out on the interest points under each cluster, the cluster center is set as the only interest point representing the building, wherein the shape of the building is used during clustering, and the geometric center of the shape of the building is obtained as the initial clustering center point. However, embodiments of the present invention are not limited to k-means clustering, and ROCK, Chemeleon, DBSCAN, STING, WaveCluster, and the like may also be used.
For example, as shown in fig. 3B, after clustering the interest points, each interest point of the cluster center is determined as an interest point associated with a corresponding building.
Then, in step S202, a logical relationship indicating the shape relationship between the interest points associated with the buildings and the buildings is established based on the description information of the cluster centers and the buildings, even if a mapping relationship is generated between each corresponding interest point and the shape information of the relevant buildings.
FIG. 4 is a schematic flow chart diagram according to yet another embodiment of the present invention; fig. 5A and 5B are schematic diagrams of a user terminal interface during use according to the embodiment of fig. 4. In the embodiment shown in fig. 4, a logical relationship has been established between the designated area surface and the interest points, and particularly, there are a limited number of interest points in the designated area surface that are of interest to the user, for example, there is only one interest point in the designated area surface that is of interest to the user. Generally, the specified area surface is an area surface of a cell type interest point, and this area surface is usually made manually and has already established a mapping relation with the interest point. In the following description only the differences with respect to the embodiment shown in fig. 2 will be described.
In step S301b, points of interest and buildings related to the designated area are obtained, for example, the user designates the area and the related points of interest and buildings by a box search method. As shown in fig. 5A, the area plane "quintech building" is specified, and the interest points "quintech building" and the building "quintech building" associated with the specified area plane are shown.
Then, in step S301c, the geographic coordinates of the area plane and the geographic coordinates of the building are compared, and if the geographic coordinates of the building fall within the range specified by the geographic coordinates of the area plane, the building is located in the area plane, i.e., the building is a building under the area plane, and the point of interest related to the area plane is the point of interest associated with the building. As shown in fig. 5B, the building "quasichi technological building" is a building under the regional level "quasichi technological building", and the interest point "quasichi technological building" is an interest point associated with the building "quasichi technological building".
Example 4 establishing a logical relationship between a Point of interest and a building based on a Point of interest group
FIG. 6 is a schematic flow chart diagram according to yet another embodiment of the present invention; 7A, 7B, 7C, and 7D are schematic diagrams of user terminal interfaces during use according to the embodiment of FIG. 6. Only a part of the steps of this embodiment will be described below, and the same steps as those of the embodiment shown in fig. 1 will be omitted.
In step 401a, a target point of interest is obtained, which is a point of interest of a specified category. For example, as shown in FIG. 7A, a target point of interest of a building class, such as "hundredth building" is searched.
Then, in step 401b, a plurality of auxiliary interest points related to the target interest point around the target interest point are obtained, and a target interest point group is constructed. Here, the auxiliary point of interest is related to the target point of interest, which means that the name of the auxiliary point of interest has a common part with the name of the target point of interest, and the common part is the name of the building. For example, as shown in fig. 7B, a building-type point of interest "hundredth building" is searched to obtain 10 subordinate points of interest, such as an entrance, a parking lot, and a door, that are located around the point of interest "hundredth building" and are related to the point of interest "hundredth building", and a target point of interest group is constructed by associating the point of interest "hundredth building" with the 10 subordinate points of interest, such as the entrance, the parking lot, and the door.
Next, in step 401c, the dependent points of interest are connected in sequence to form a dependent point of interest connection graph. Particularly, each auxiliary interest point or target interest point group is denoised, and then the auxiliary interest points are sequentially connected to form an auxiliary interest point connection graph. As shown in fig. 7C, the interest point 1 is close to the interest point 5, the interest points 2, 9 and 6 are close to each other, the interest points 1, 6 and 9 are regarded as noise, and after denoising, the interest points 1, 8, 7, 10, 3 and 2 are connected together in sequence to form a closed shape, i.e., a connected graph of subordinate interest points.
Next, in step 401d, the buildings under the scope of the auxiliary point of interest connection graph are obtained, and it is determined that the target point of interest is the point of interest associated with the buildings under the scope of the auxiliary point of interest connection graph. As shown in fig. 7D, the subordinate point of interest connection graph encloses a building "hundredth building", which is a building under the scope of the subordinate point of interest connection graph, and the target point of interest "hundredth building" is a point of interest associated with the building "hundredth building".
Embodiment 5 based on the description information of the name, address, etc. of the known building and the description information of the interest point, the logical relationship between the interest point and the building is established
Fig. 8 is a schematic flow chart diagram according to yet another embodiment of the present invention. Only the steps different from the embodiment shown in fig. 1 will be described below.
In step 501a, a building set having at least description information of name, address, and shape is abstracted into a point of interest, and a first point of interest set is obtained, where the point of interest has at least description information of name and geographic coordinates, and the coordinates of the point of interest are taken as a geometric center point of the shape of the building.
Then, in step 501b, the user terminal obtains a second set of points of interest, where the user terminal is, for example, a mobile phone, an ipad, or the like.
Next, in step 501c, the first interest point set and the second interest point set are compared, a coincident interest point in the first interest point set and the second interest point set is obtained, and the coincident interest point is determined as an interest point associated with the building.
In step 502, according to the matching relationship between the building set and the first interest point set, the building description information of the building set is matched with the interest points associated with the building.
There is also provided, in accordance with an embodiment of the present invention, apparatus for establishing a logical relationship between a point of interest and a building. As shown in fig. 9, the apparatus includes a building and interest point obtaining unit D1, configured to obtain a building and an interest point associated with the building, where the description information of the building includes shape information and geographic coordinates of the building, and the description information of the interest point includes a name and geographic coordinates of the interest point; a building mapping unit D2 for building a logical mapping between the shape information of the associated building and the points of interest; a display unit D3 for displaying the shape of the building.
