[0042] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by a person of ordinary skill in the art without creative effort belong to the scope of protection of the present application.

[0043] Please refer to Figure 1 , Figure 1 is a flowchart of a three-dimensional building table construction method provided by an embodiment of the present application. The three-dimensional building table construction method comprises the following steps.

[0044] S1: acquiring real property right data and a corresponding two-dimensional building table, and constructing a three-dimensional building table according to the real property right data;

[0045] As one of the optional embodiments, the step of acquiring real property right data and a corresponding two-dimensional building table, and constructing a three-dimensional building table according to the real property right data comprises the following steps.

[0046] acquiring real property right data and a corresponding two-dimensional building table;

[0047] vectorizing a layered household diagram in the real property right data to obtain a house datum plane and a household datum plane of each house property object;

[0048] performing spatial position registration on the house datum plane according to natural building data and house measurement positioning point data in the real property right data to obtain a registered house datum plane;

[0049] combining household datum planes on the basis of the registered house datum plane according to natural building numbers, floor numbers and household numbers in the real property right data to obtain combined household datum planes, and establishing a mapping relationship between the two-dimensional building table and the corresponding datum planes;

[0050] stretching the combined household datum planes according to floor heights and floor numbers of different households in the real property right data to form a three-dimensional building model, and displaying corresponding household numbers on the three-dimensional building model to form a three-dimensional building table.

[0051] Specifically, first, a layered household diagram in a DWG, PDF or JPG format in the real property right data is vectorized into a SHP format to form a two-dimensional datum plane of a single real property house property object, including a house datum plane and a household datum plane.

[0052] Then, the natural building data and the house survey positioning point data obtained are combined with the real estate property data, the house datum is spatially registered to become a two-dimensional vector plane with spatial information. Meanwhile, the registered house is combined with the attribute data in the real estate property data, such as natural building number, floor number, and house number, to form a logical relationship of "natural building-floor-house-two-dimensional vector plane", so that the two-dimensional building list and the two-dimensional vector plane of the house can be mapped based on the logical relationship.

[0053] Further, the combined house datum is stretched to different datums according to the floor height and floor number in the real estate property data to form a three-dimensional building model, and then the corresponding house number is displayed on the periphery of the three-dimensional building model to form a three-dimensional building list.

[0054] It should be noted that the building list in the embodiment of the application can include a single building or multiple buildings.

[0055] S2: Obtain a tilt photography image of a building corresponding to the three-dimensional building list, and correct the height of the building in the three-dimensional building list according to the height information of the tilt photography image;

[0056] The tilt photography image refers to a ground image taken from an inclined angle, which is usually obtained by aerial photography (such as a drone), and can provide rich three-dimensional information and can more truly reflect the appearance and morphology of the ground object.

[0057] As one of the optional embodiments, after the tilt photography image of the building corresponding to the three-dimensional building list is obtained, the method further includes:

[0058] According to the coordinate information in the tilt photography image, the position of the three-dimensional building list is registered and corrected so that the position of the bottom surface of the building in the three-dimensional building list is consistent with the position of the corresponding building plane on the tilt photography image.

[0059] Specifically, the three-dimensional building list and the three-dimensional tilt photography image of the building area are positionally registered and corrected according to the coordinate information, so that the bottom surface of the three-dimensional building list and the corresponding real estate unit building plane range on the tilt photography image are consistent in the plane position.

[0060] As one of the optional embodiments, the correction of the height of the building in the three-dimensional building list according to the height information of the tilt photography image includes:

[0061] According to the height information of the tilt photography image, the image height corresponding to the building of the three-dimensional building list is obtained.

[0062] According to the building bottom height information in the height information, the bottom starting height of the building in the three-dimensional building table is adjusted, so that the starting height of the building in the adjusted three-dimensional building table is consistent with the starting height of the building in the corresponding oblique photography image;

[0063] According to the image height of the building, the building height of the three-dimensional building table is overall averaged and finely adjusted layer by layer, so that the building in the adjusted three-dimensional building table is consistent with the height of the building in the corresponding oblique photography image.

[0064] As one of the optional embodiments, the image height corresponding to the building in the three-dimensional building table is obtained according to the height information of the oblique photography image, comprising:

[0065] According to the range of the building reference surface of the bottom layer of the building in the three-dimensional building table, the range of the corresponding building in the oblique photography image is determined, and the first height information in the range of the oblique photography image is obtained;

[0066] Based on the first height information, a local outlier factor detection method is used to remove the outliers in the first height information, to obtain the second height information;

[0067] The difference between the maximum value and the minimum value in the second height information is calculated to obtain the image height corresponding to the building in the three-dimensional building table.

[0068] Specifically, based on the three-dimensional building table that has been constructed, the bottom layer building reference surface of the building model needs to be determined first, which represents the contact surface between the building and the ground. By traversing all the height points within the two-dimensional reference surface range in the three-dimensional oblique photography image data, the height data of these points is collected, so as to obtain the detailed height information of the building ground position, thereby realizing the true reflection of the actual height of the ground.

[0069] Further, the data of the oblique photography image may be affected by various factors, resulting in outliers (such as measurement errors, noise, etc.) in the height information. In order to improve the accuracy of the height adjustment of the three-dimensional building table, the height data needs to be cleaned and processed. First, the local outlier factor detection method (Local Outlier Factor, LOF) is used to remove the abnormal points with LOF value greater than 1, and then the difference between the maximum value and the minimum value of the processed height points is calculated to obtain the image height corresponding to the building. By removing these abnormal points, the noise and errors in the data can be eliminated, and the accuracy of the data can be improved.

[0070] As one of the optional embodiments, the image height corresponding to the building in the three-dimensional building table is obtained according to the height information of the oblique photography image, comprising:

[0071] The difference between the image height of the building and the building height of the three-dimensional building table before adjustment is calculated to obtain a height difference value;

[0072] The height difference value is evenly divided to each floor according to the number of floors of the building in the three-dimensional building table to adjust the building height of the three-dimensional building table to obtain an adjusted three-dimensional building table.

[0073] Specifically, the difference value is calculated according to the building image height and the height of the existing three-dimensional building table, and the difference value is evenly divided to the floors in combination with the number of floors of the building table, so that the overall height of the three-dimensional building table is adjusted to form a new three-dimensional building table. The adjusted three-dimensional building table is consistent with the image in height. This process is to ensure the consistency of the three-dimensional building model and the building in the image in height and spatial position.

[0074] S3: using the coding ID of the housing property object in the building table as an association key value, associating the two-dimensional building table with the three-dimensional building table to enable dynamic interaction between the two-dimensional building table and the three-dimensional building table;

[0075] Specifically, each housing property object has a unique coding ID as a unique identifier between the three-dimensional model and the attribute data. The housing property object uses the unique coding ID as the association key value of the model and the attribute to automatically rotate the selected housing object to the front of the main view angle, so that the two-dimensional and three-dimensional models and the oblique photography image can be associated and interacted. Through the interaction, the user can conveniently select the housing object of the ring-shaped tower based on the two-dimensional building table, and through the automatic rotation of the three-dimensional building table direction, the currently selected three-dimensional real estate object is located in the front of the main view angle, facilitating the positioning of the three-dimensional housing object behind the ring-shaped tower.

[0076] Further, by establishing the primary key association between the two-dimensional and three-dimensional building tables, based on the logical relationship of "land-natural building-natural house", the natural building number of the natural house is associated through the natural building number of the natural house, so that the house can be associated to the corresponding building; the land code of the land is associated through the land code of the land, so that the house and the building can be mapped to the land.

[0077] As one of the optional embodiments, the dynamic interaction between the two-dimensional building table and the three-dimensional building table includes:

[0078] When the housing property object in the two-dimensional building table is selected, the corresponding housing property object in the three-dimensional building table is automatically rotated to the front of the main view angle.

[0079] Specifically, in application, based on the user's selection in the two-dimensional real estate table, the viewing angle of the three-dimensional real estate table can be automatically adjusted. Through this dynamic viewing angle adjustment, the selected house object automatically rotates to the front of the main viewing angle. The embodiment of the present application enables the user to more intuitively view the position and appearance of the selected house object in the three-dimensional model, especially for complex structures such as ring-shaped towers, it is convenient to view the hidden house object.

[0080] Through this association and linkage mechanism, the user can conveniently switch between different viewing angles and quickly locate and view the required house object. This interactive design greatly improves user experience and operation efficiency, especially when dealing with complex three-dimensional structures and real estate data, it provides a more intuitive and efficient operation method.

[0081] S4: According to the attribute information of the house property object in the real estate table, different colors are used for rendering and display in the two-dimensional real estate table and the three-dimensional real estate table, and a three-dimensional real estate table linked with the two-dimensional real estate table is output.

[0082] Specifically, according to the different attribute information of the real estate object (such as ownership type, use right type, mortgage state, etc.), different colors are used for rendering in the two-dimensional and three-dimensional real estate table, and each color represents a specific right state. Through this color coding, the user can quickly and intuitively understand the right state and legal attributes of each real estate object, which is convenient for further analysis and decision-making.

[0083] As one of the optional embodiments, before outputting the three-dimensional real estate table linked with the two-dimensional real estate table, the method further comprises:

[0084] Set the transparency of the three-dimensional real estate table to adjustable transparency;

[0085] When the transparency is adjusted to zero, the transparency of the three-dimensional real estate table is set to zero, and the real scene corresponding to the oblique photography image is displayed.

[0086] Specifically, in the three-dimensional floor plan table, the user can adjust the transparency of the model and the number of displayed floors. By adjusting the transparency, the user can view the internal structure of the building or hide the model to observe other information in the lower layer or background. When the transparency is set to 0, the three-dimensional floor plan table is not displayed at all, and in this mode, the user can clearly see the real scene presented by the oblique photography image, so as to better understand the spatial relationship between the building and the surrounding environment. By combining the oblique photography image, the user can choose to display or hide the three-dimensional floor plan table when observing the three-dimensional model, so as to directly see the appearance of the building and the surrounding environment presented by the image data. Combined with the data display of the actual image and the three-dimensional model, the user can more comprehensively analyze the spatial position and surrounding environment of the real estate object, so as to better plan and make decisions.

[0087] The embodiment of the present application realizes the spatial linkage of the three-dimensional floor plan table and the real world through the adaptive matching of the oblique photography image and the three-dimensional data table, solves the problem of lack of real scene auxiliary positioning of the floor plan table, and makes the three-dimensional floor plan table more accurately express the real situation of the floor plan; through the dynamic interactive linkage of the two-dimensional floor plan table and the three-dimensional floor plan table, when the user selects a housing object of a ring tower in the two-dimensional floor plan table, the three-dimensional floor plan table can be automatically rotated in the direction, so that the currently selected housing object is located in front of the main view angle, which is convenient for positioning the three-dimensional housing object behind the ring tower, and solves the problems of insufficient spatial information of the two-dimensional floor plan table alone and inconvenient selection of the tower model in the three-dimensional floor plan table; by setting the transparency of the three-dimensional floor plan table, the real scene of the floor plan can be viewed. The embodiment of the present application not only can efficiently organize and display real estate information, but also improves the operation efficiency and experience of the user in the process of real estate management and analysis.
