[0033] Figure 1is a flowchart of a method for determining building height provided by an embodiment of the present invention, which is applied to a client, such as Figure 1 As shown, the method may include:

[0034] Step 101, obtaining the address of a point of interest; the address of the point of interest includes a plurality of sequentially connected geographic entities.

[0035] In the embodiment of the present invention, Geographic Information System In the POI, a point of interest (POI) address can be a house, a shop, a post box, a bus stop, etc. For example, a POI address is the address of XX Building. In order to accurately describe the address of XX Building, it is necessary to connect multiple geographic entities in a certain order to obtain the POI address. Then the complete POI address can be: XX Province / XX City / XX District / XX Building / XX Floor / XX Number. Among them, XX Province, XX City, XX District, XX Building, XX Floor, and XX Number are all geographic entities. In addition, because the POI address is the address of XX Building, the XX Building in the POI address can also be used as the POI in the POI address.

[0036] In this step, all or part of the POI addresses may be obtained from the POI database to serve as a screening range for subsequent screening.

[0037] Step 102: Determine, from all the POI addresses, a target POI address that includes a target geographic entity corresponding to a target building.

[0038] In the embodiment of the present invention, in order to determine the height of the target building, it is necessary to filter out the target POI address containing the target geographic entity corresponding to the target building from all POI addresses. The target building is generally XX Building, XX Building, XX Apartment, etc.

[0039] For example, in order to determine the height of Tus-Tech Building, the target POI addresses that can be found are as follows: target POI address 1 with "Hui Jin Suo Co., Ltd." as the POI: "28th Floor, Building D, Tus-Tech Building, Haidian District, Beijing"; target POI address 2 with "Saier Investment Co., Ltd." as the POI: "Room 1103, 11th Floor, Building D, Tus-Tech Building, No. 8, Tsinghua Science Park, Yard 1, Zhongguancun East Road, Haidian District, Beijing", etc., among which, target POI address 1 and target POI address 2 both contain the target geographic entity "Tus-Tech Building", and also include information on geographic entities related to the floor number and room number of Tus-Tech Building.

[0040] Step 103: Determine the maximum number of floors of the target building according to the address of the target point of interest.

[0041] In the embodiment of the present invention, since the height of a single floor of a building is a preset height according to the building code, in order to determine the overall height of the building, it is necessary to first determine the maximum number of floors of the building. Since the target POI address usually includes information about geographic entities related to the floor number and room number of the target building, the maximum number of floors of the target building can be determined by extracting information about geographic entities related to the floor number and room number from the target POI address.

[0042] For example, for the target POI address 1 with "Huijinso Company" as the POI: "28th Floor, Building D, Tus-Tech Building, Haidian District, Beijing"; the target POI address 2 with "Saier Investment Co., Ltd." as the POI: "1103, 11th Floor, Building D, Tus-Tech Building, No. 8, Tsinghua Science Park, Yard 1, Zhongguancun East Road, Haidian District, Beijing", the floor information of the target building Tus-Tech Building can be extracted as 11th and 28th floors. If there are enough target POI addresses, more information related to the floor geographic entities of Tus-Tech Building will be obtained. If the information analysis of a large number of floor geographic entities shows that the 28th floor is the largest number of floors, the 28th floor can be determined as the maximum number of floors of the target building Tus-Tech Building.

[0043] Step 104, determining the building height of the target building according to the preset correspondence between the number of floors and the building height, and the maximum number of floors of the target building.

[0044] In an embodiment of the present invention, according to the requirements of building specifications, the height of a single floor of a building is generally a preset value, and buildings with different numbers of floors have different building heights. Therefore, a corresponding relationship between the number of floors and the building height can be established in advance. For example, the height of a building with a total height of 27 floors is 86 meters, and the height of a building with a total height of 28 floors is 89 meters… In this step, since the maximum number of floors of the target building is obtained, the building height corresponding to the maximum number of floors of the target building can be obtained through the corresponding relationship between the number of floors and the building height, and the building height is determined as the building height of the target building.

[0045] For example, if the maximum number of floors of the target building is 28, then through the correspondence between the number of floors and the building height, it can be obtained that the building height of the target building is 89 meters.

[0046] After obtaining the building height of the target building, when rendering the 3D display model of the target building in the map software, the height of the 3D display model of the target building can be rendered by the building height, thereby obtaining a more realistic and accurate rendering display effect. For a dense building complex, the height difference between different buildings can be clearly reflected, thereby providing a realistic scene display effect.

[0047] In summary, an embodiment of the present invention provides a method for determining the building height, by obtaining a point of interest address; the point of interest address includes multiple sequentially connected geographic entities; from all point of interest addresses, a target point of interest address including a target geographic entity corresponding to a target building is determined; according to the target point of interest address, the maximum number of floors of the target building is determined; according to the preset correspondence between the number of floors and the building height, and the maximum number of floors of the target building, the building height of the target building is determined. The embodiment of the present invention extracts information related to the floors of the target building based on the target point of interest address including the target geographic entity corresponding to the target building, thereby obtaining the maximum number of floors of the target building, and finally calculating the building height of the target building. The entire process can quickly obtain an accurate building height without paying a lot of manpower or financial costs.

[0048] Figure 2 is a flowchart of the specific steps of a method for determining building height provided by an embodiment of the present invention, such as Figure 2 As shown, the method may include:

[0049] Step 201: Determine the location of the target building.

[0050] In the embodiment of the present invention, since a massive amount of POI address data is stored in the POI database, directly screening the target point of interest addresses containing the target geographic entity corresponding to the target building from the massive amount of POI address data will result in a large amount of data processing. Therefore, a preliminary screening range can be determined through appropriate preliminary screening to reduce the amount of data processing for subsequent screening.

[0051] In this step, the location of the target building can be obtained, so that the POI addresses within a certain range centered on the location of the target building can be determined as a preliminary screening range.

[0052] Step 202: Obtain the point of interest addresses of buildings within a preset range around the location of the target building.

[0053] In this step, after the location of the target building is determined, the point of interest addresses of buildings within a preset range around the location of the target building can be obtained as a preliminary screening range, so that subsequent screening operations can be performed to include the target point of interest addresses of the target geographic entities corresponding to the target building, thereby reducing the amount of data processing.

[0054] For example, if the height of office building A needs to be estimated, all POI addresses within a 100-meter range around office building A can be obtained from the POI database.

[0055] Step 203: segment the POI address into geographic entities to obtain corresponding relationships between multiple geographic entities in the POI address.

[0056] In the embodiment of the present invention, the geographic entity segmentation of the address specifically refers to segmenting geographic entities of different meanings or types in the address, and the segmentation granularity is a complete independent entity. For example, for the POI address: 28th Floor, Building D, Tus-Tech Building, Haidian District, Beijing, the segmentation result is: "28th Floor, Building D, Tus-Tech Building, Haidian District, Beijing". Each independent granularity after segmentation is a geographic entity.

[0057] Step 204: Determine, based on the corresponding relationship, the address of the target point of interest including the target geographic entity corresponding to the target building.

[0058] After obtaining the correspondence between multiple geographic entities in the segmented POI addresses, the target POI addresses containing the target geographic entities corresponding to the target building can be filtered out. For example, if the target building is Tus-Tech Building, the POI addresses containing the independent geographic entity of Tus-Tech Building are filtered out from all the segmented POI addresses as the target POI addresses.

[0059] Optionally, step 204 may specifically include:

[0060] Sub-step 2041: Determine the actual name and alias of the target building.

[0061] Sub-step 2042: Determine a target geographic entity corresponding to the actual name or alias of the target building.

[0062] Sub-step 2043: determining the address of a target point of interest that contains the target geographic entity or a similar geographic entity whose similarity to the target geographic entity is greater than a preset threshold.

[0063] In actual applications, there may be multiple names for buildings, such as new and old names, aliases, colloquial names, etc., which means that any of these names may be used when constructing a POI address, and these names all represent the same building. Therefore, in order to improve the screening accuracy, the embodiment of the present invention can first determine the actual name and alias of the target building, and during the specific screening, determine the target geographic entity corresponding to the actual name or alias of the target building, and determine the target point of interest address containing the target geographic entity, or containing a similar geographic entity whose similarity to the target geographic entity is greater than a preset threshold. This ensures that the screening process does not miss geographic entities that use the alias or similar name of the target building, thereby improving the completeness and compatibility of the screening.

[0064] In addition, after the POI address is segmented and the geographic entity is extracted, it is matched with the target building, and there may be incomplete matches. For example, for the target building Tus-Tech Building, there is a situation where "Tus-Tech Building D" and "Tus-Building D" are inconsistent in expression but actually refer to the same thing, which will lead to a low matching degree. The corresponding measures taken by the embodiment of the present invention include: lowering the matching threshold, or using multiple aliases of the target building to find the highest matching object, or using word weight analysis to reduce the influence of unimportant words such as "technology" so that it can complete the match. It is also possible to use POI aggregation and map POI search text semantic matching methods for matching, which is not limited by the embodiment of the present invention.

[0065] Step 205: extracting geographic entities related to the room number and / or floor number from the target point of interest address.

[0066] In an example, in order to determine the height of the TusPark, target POI addresses that can be found include: target POI address 1 with "Hui Jin Suo Co., Ltd." as the POI: "28th Floor, Building D, TusPark, Haidian District, Beijing"; target POI address 2 with "Saier Investment Co., Ltd." as the POI: "Room 1103, 11th Floor, Building D, TusPark, No. 1, Zhongguancun East Road, Haidian District, Beijing", etc., where both target POI address 1 and target POI address 2 contain the target geographic entity "TusPark", and also include information on geographic entities related to the floor number and room number of the TusPark.

[0067] Step 206: Determine at least one floor number according to the geographical entity associated with the room number and / or floor number.

[0068] For the above example, we can extract the geographical entities "11th floor" and "28th floor" which are directly related to the floor number, thereby determining the two floor numbers. In addition, for the above example, we can also extract the geographical entity "1103" which is directly related to the room number. Since the room number has certain naming rules, the floor number is encoded in the preset position of the room number during the naming and encoding process. In this example, the first two digits of the room number are used to represent the floor where the room is located. Therefore, by extracting the first two digits of the room number "1103", we can get a floor number.

[0069] Step 207: determine the maximum number of floors among the at least one number of floors as the maximum number of floors of the target building.

[0070] In this step, if it is found that XX floors is the maximum number of floors through information analysis of a large number of floor geographic entities, then XX floors can be determined as the maximum number of floors of the target building.

[0071] Step 208: Determine the building height of the target building according to the preset correspondence between the number of floors and the building height, and the maximum number of floors of the target building.

[0072] For details of this step, please refer to the relevant description of the above step 104, which will not be repeated here.

[0073] Optionally, before step 208, the method may further include:

[0074] Step 209: A sample acquisition module is used to obtain the number of floors and actual building height of the sample building.

[0075] In an embodiment of the present invention, the sample buildings may be some buildings selected in advance, and the number of floors and actual building heights of the sample buildings are relatively easy to obtain. Specifically, the number of floors and actual building heights of the sample buildings may be obtained through information provided by the builders, reference to public information, field surveys, etc.

[0076] Step 210, a calculation module is used to calculate the average building height corresponding to the same number of floors according to the number of floors and the actual building height, and establish a corresponding relationship between the number of floors and the average building height.

[0077] In an embodiment of the present invention, different buildings may have slight differences in single-story heights depending on actual construction and demand. Therefore, in order to obtain a more accurate and wider applicable correspondence between floors and building heights, the embodiment of the present invention can first calculate the average building height corresponding to the same number of floors, and then establish a correspondence between the number of floors and the average building height for subsequent search.

[0078] For example, due to the different designs of single-story heights, the actual building height of the 30-story sample building A is 100 meters, the actual building height of the 30-story sample building B is 140 meters, and the actual building height of the 30-story sample building C is 180 meters. After average value calculation, the average building height corresponding to 30 floors is 140 meters.

[0079] After executing step 210, step 208 can be specifically implemented by determining the building height of the target building according to the corresponding relationship between the number of floors and the average building height, and the maximum number of floors of the target building.

[0080] By calculating the average value, the building height corresponding to each floor number is averaged, so that the average building height corresponding to the floor number is more applicable to various building design requirements. By finding and determining the building height of the target building through the correspondence between the floor number and the average building height, more accurate and applicable results can be obtained.

[0081] Optionally, the method may further include:

[0082] Step 211: When constructing a three-dimensional map, render a model of the target building according to the building height of the target building and a preset scale factor.

[0083] In an embodiment of the present invention, when constructing a three-dimensional map, it is usually necessary to render the buildings in three dimensions, which requires first obtaining the building height of the buildings in order to accurately render the features of the buildings in the height direction. When there are multiple buildings in an area, accurate rendering of the features of the buildings in the height direction can clearly express the height difference relationship between the buildings in the area.

[0084] In this step, when constructing a three-dimensional map, the model of the target building can be rendered according to the building height of the target building obtained in step 208 and the preset scale factor. The building height of the target building helps to accurately render the characteristics of the target building in the height direction.

[0085] For example, the building height of the target building is 100 meters, and the preset scale factor may be one ten-thousandth. Then, when constructing the target building on the map in the three-dimensional mode, the height of the model of the target building is 1 centimeter.

[0086] In summary, an embodiment of the present invention provides a method for determining the building height, by obtaining a point of interest address; the point of interest address includes multiple sequentially connected geographic entities; from all point of interest addresses, a target point of interest address including a target geographic entity corresponding to a target building is determined; according to the target point of interest address, the maximum number of floors of the target building is determined; according to the preset correspondence between the number of floors and the building height, and the maximum number of floors of the target building, the building height of the target building is determined. The embodiment of the present invention extracts information related to the floors of the target building based on the target point of interest address including the target geographic entity corresponding to the target building, thereby obtaining the maximum number of floors of the target building, and finally calculating the building height of the target building. The entire process can quickly obtain an accurate building height without paying a lot of manpower or financial costs.
