Description

Technical Field

[0001] The present invention relates to the field of geographic information and digital fusion technology, and in particular to a fusion method, system, terminal and computer-readable storage medium of a three-dimensional cadastral and digital twin platform. Background Art

[0002] The three-dimensional cadastral system is the core of three-dimensional land management. Relying on the three-dimensional property rights body as a spatial operation unit, it can realize the expression, modeling, calculation and analysis of land space.

[0003] However, land resources and physical objects in reality are often inseparable. When describing a piece of land, it is usually called "a certain type of land", such as forest land, grassland, construction land, etc. This is not a problem in a two-dimensional system, but in a three-dimensional system, the overlap between space and matter should be described separately.

[0004] The traditional three-dimensional cadastral system only considers land space issues, which leads to the current three-dimensional land management being unable to well realize the reality of "managing things with land (space)" (also known as three-dimensional management of matching "space" and "matter". In the three-dimensional cadastral system, "space = land", while in the digital twin platform, "forest, grassland or building = matter"). This makes it easy for staff to ignore the "matter" existing in the "space", resulting in problems such as information mismatch in the formulated plans, thus causing unnecessary disputes. Therefore, it has become an urgent need to achieve the connection between the "three-dimensional cadastral system for managing property space" and the "digital twin platform for expressing physical space".

[0005] Therefore, the prior art still needs to be improved and developed. Summary of the invention

[0070] In order to make the purpose, technical solution and advantages of the present invention clearer and more specific, the present invention is further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0071] The method for integrating the three-dimensional cadastral data with the digital twin platform described in the preferred embodiment of the present invention is as follows: Figure 1As shown, the method for integrating the three-dimensional cadastral data with the digital twin platform includes the following steps:

[0072] Step S10: Acquire multiple three-dimensional information elements in the three-dimensional cadastral coordinate system and multiple digital information elements in the digital coordinate system of the target detection area, perform traversal detection on all the three-dimensional information elements and all the digital information elements, obtain a first association relationship between the three-dimensional cadastral coordinate system and the digital coordinate system, and construct a unified window and an association set according to the first association relationship.

[0073] Among them, the three-dimensional cadastral coordinate system includes: a three-dimensional geographic coordinate system, a three-dimensional local coordinate system and a three-dimensional component coordinate system; the digital coordinate system includes: a digital geographic coordinate system, a digital local coordinate system and a digital component coordinate system; that is, each coordinate system includes a geographic coordinate system, a local coordinate system and a component coordinate system. Among them, the geographic coordinate system refers to the latitude and longitude coordinate system, which is used to represent coordinates in a large scale range; the local coordinate system is a coordinate system for medium-scale elements, which is mainly oriented to three-dimensional plots in the three-dimensional cadastral system (a three-dimensional plot refers to a plot that is closed in the land ownership boundary and can be used independently, and is a space where the right to use construction land is established on the ground, on the surface or underground), and is mainly oriented to buildings in the digital twin environment; the component coordinate system is a relative positioning coordinate system based on the local coordinate system, for example, the position of a door in the floor and room of a building. Through these three coordinate systems, all elements in the three-dimensional cadastral coordinate system and the digital coordinate system can be described in the form of coordinates. Furthermore, one, two or all of these three coordinate systems may exist in the three-dimensional cadastral coordinate system and the digital coordinate system.

[0074] Specifically, the three-dimensional cadastral coordinate system and the digital coordinate system of the target detection area are obtained, and all three-dimensional information elements in the three-dimensional cadastral coordinate system and all digital information elements in the digital coordinate system are read; all the three-dimensional information elements and all the digital information elements are traversed, and the three-dimensional geographic coordinate system and the digital geographic coordinate system are aligned according to all the three-dimensional information elements and all the digital information elements to obtain the target geographic coordinate system information:

[0075] ; ;in, Represents a three-dimensional cadastral coordinate system; Represents the coordinate system name in the 3D cadastral coordinate system, including the 3D geographic coordinate system, 3D local coordinate system and 3D component coordinate system; Representing three-dimensional information elements; Represents a digital coordinate system; The coordinate system name representing the digital coordinate system, including the digital geographic coordinate system, the digital local coordinate system and the digital component coordinate system; Representing digital information elements; after importing the target geographic coordinate system information into the digital local coordinate system, aligning multiple three-dimensional information elements with the digital local coordinate system to obtain multiple change values, and aligning the three-dimensional local coordinate system with the digital local coordinate system according to all the change values ​​to obtain compensation information; reading multiple site information existing in the digital local coordinate system in the target detection area, associating all the site information with multiple three-dimensional information elements to obtain a centralized property object set, searching for spatial information of a component of a centralized property object in the centralized property object set, matching the spatial information with the corner points of the centralized property object to obtain the corner point translation, and translating the compensation information according to the corner point translation to align the three-dimensional component coordinate system with the digital component coordinate system to obtain a first association relationship between the three-dimensional cadastral coordinate system and the digital coordinate system; constructing a unified window according to the first association relationship, and screening all the three-dimensional information elements associated with any of the digital information elements to construct an association set, and importing the association set into the unified window.

[0076] Among them, Figure 2 As shown, the three-dimensional cadastral coordinate system and the digital coordinate system in the target detection area input by the user are obtained, and the respective information elements in the three-dimensional cadastral coordinate system and the digital coordinate system, namely the three-dimensional information elements and the digital information elements, are extracted and recorded respectively as and ; Then the geographic coordinate system, local coordinate system and component coordinate system in the three-dimensional cadastral coordinate system and the digital coordinate system are respectively aligned, so as to achieve the initial integration of the three-dimensional cadastral coordinate system and the digital coordinate system, and provide a basis for the subsequent acquisition of the three-dimensional property body component set, thereby improving the effectiveness and accuracy of the three-dimensional property body in the digital twin environment.

[0077] Furthermore, the target geographic coordinate system information is imported into the digital local coordinate system to obtain local coordinate system information in the digital local coordinate system; a preset number of three-dimensional information elements are selected and imported into the digital local coordinate system to obtain corresponding local coordinate system information that matches each other, and the plane translation, rotational translation and vertical translation between the preset number of three-dimensional information elements and the corresponding local coordinate system information are calculated based on all the local coordinate system information; the local coordinate system information is moved according to the plane translation, rotational translation and vertical translation to align the three-dimensional local coordinate system and the digital local coordinate system to obtain compensation information.

[0078] The variation values ​​include: plane translation, rotational translation and vertical translation.

[0079] First, align the geographic coordinate system: with the help of open source database, traverse , all three-dimensional information elements are recorded as , traverse , all digital information elements are recorded as , and then call the format conversion function in the database (for example, gdal.Translate()) and The value of In, output That is the target geographic coordinate system information after the geographic coordinate system is aligned. It refers to the parameter value after the coordinate system is converted into a common coordinate system; and, if no three-dimensional information elements or digital information elements are detected, there is no need to align the geographic coordinate systems in the three-dimensional cadastral coordinate system and the digital coordinate system.

[0080] Furthermore, the local coordinate systems in the three-dimensional cadastral coordinate system and the digital coordinate system are aligned: the target geographic coordinate system information is input into the preset projection coordinate system (i.e., the digital local coordinate system of the digital twin environment), and a point that matches the three-dimensional cadastral system is marked as the first matching point (including the point in the digital local coordinate system and the point in the three-dimensional cadastral system), and the translation between the two matching points is calculated. , mark the second matching point in the same way and calculate the plane rotation angle , mark the third matching point and calculate the vertical rotation angle , at this time, According to the translation After translation, rotate the plane according to the angle and vertical rotation angle Rotate to get compensation information , so as to realize the registration of the local coordinate system in the three-dimensional cadastral coordinate system and the digital coordinate system.

[0081] Furthermore, if Figure 3 As shown, the component coordinate systems in the 3D cadastral coordinate system and the digital coordinate system are aligned: First, before aligning the component coordinate system, it is necessary to ensure that the digital twin environment is at the BIM (Building Information Modeling, a building information model), CIM (City Information Modeling, city information model) component level or a more refined level, and that there are 3D property objects in the 3D cadastral system. By reading the site information in the digital information element and the 3D parcel information in the 3D information element, and associating the site information with the 3D parcel information, any centralized property object in the 3D parcel can be located. , thereby constructing a centralized property rights object set, from which any Packaged components , and search for the spatial information of this component, so as to match this spatial information with The corner points between them are used to obtain the corner translation, and then the compensation information is The translation is performed according to the corner point translation amount. At this time, the alignment of the three-dimensional component coordinate system and the digital component coordinate system is completed, that is, the alignment between the three-dimensional cadastral coordinate system and the digital coordinate system, and the first association relationship between the three-dimensional cadastral coordinate system and the digital coordinate system is obtained. According to the first association relationship, an association set can be constructed. At the same time, the aligned three-dimensional cadastral coordinate system, the digital coordinate system and the association set can be imported into the constructed unified window, which unifies the existing elements in the three-dimensional cadastral coordinate system and the digital coordinate system, effectively avoids the neglect of material elements in the space, and improves the accuracy and completeness of the detection of the target detection area.

[0082] Furthermore, in the process of building the association set, it is necessary to traverse all the site information and take each one that is related to any centralized property object. The associated site information objects are added to the associated set, and the non-intersecting parts are also added to a set, recorded as the detection set. Among them, Figure 4 As shown, for the associated set, it also includes the cases of complete inclusion and intersection. If it is the case of intersection, it is necessary to calculate the volume of the intersection of the site information and the corresponding centralized property rights object.

[0083] Step S20: In the unified window, define a first spatial range of the target detection area, traverse all the three-dimensional information elements and all the digital information elements in the first spatial range to obtain a final spatial range, intercept multiple three-dimensional information elements and multiple digital information elements according to the final spatial range to obtain an intercepted data set, and import the intercepted data set into the constructed microenvironment platform for construction processing to obtain a three-dimensional property body component set.

[0084] Among them, Figure 5 As shown, in the unified window, you can manually draw and use the coordinate picking tool to pick coordinates, which should include at least 4 three-dimensional coordinates to form the first spatial range, or enter the three-dimensional coordinates using the input box, which should include at least 4 three-dimensional coordinates to form the first spatial range. After defining the range, a spatial set will be formed. , which records all the three-dimensional information elements and digital information elements within this space; among them, the triangulated network structures such as CIM terrain and real-life three-dimensional terrain contained in the digital twin system are non-object elements and are not included in the middle.

[0085] Specifically, receiving coordinate information input by a user, defining a first spatial range of the target detection area in the unified window according to the coordinate information, and constructing a spatial set according to all three-dimensional information elements and all digital information elements within the first spatial range: ;in, represents a spatial set, Represents the three-dimensional information elements within the first spatial range, Representing digital information elements within a first spatial range; obtaining the center point and all corner points of the first spatial range, obtaining the connecting lines between the center point and each of the corner points, and obtaining a collapse surface based on all the connecting lines. If the collapse surface intersects with an element in the spatial set, the longest connecting lines are deleted one by one until the collapse surface does not intersect with the elements in the spatial set, thereby obtaining a final spatial range; intercepting all the three-dimensional information elements and all the digital information elements within the final spatial range to construct an intercepted data set, and importing the intercepted data set into the constructed microenvironment platform; obtaining a construction instruction input by a user in the microenvironment platform, updating the intercepted data set according to the construction instruction, and obtaining a three-dimensional property body component set.

[0086] Among them, Figure 6 As shown, the center point of the first spatial range is connected to all corner points, and the corner points corresponding to the longest connecting line are deleted one by one, and the adjacent point sets are reconnected to form a collapsed surface, and it is determined whether the collapsed surface is consistent with the spatial set. If the elements in intersect, return to the previous step and select the corner point corresponding to the second longest connecting line to perform the above steps until the space set All elements in have been traversed, or the final space has been obtained .

[0087] Furthermore, the data of the 3D cadastral coordinate system and the digital coordinate system in the final space are intercepted, and the intercepted data is imported into the constructed micro-environment platform. The process of data interception of the 3D cadastral system and the digital twin system refers to the triangulation structure of the CIM terrain, real 3D terrain, etc. in the digital twin system. The data is intercepted within the range of ) and texture images (denoted as The intercepted data set is recorded as , importing the input into the micro-environment platform is conducive to improving the convenience of user operation.

[0088] Furthermore, a construction instruction input by a user is obtained in the microenvironment platform, and all digital information elements in the intercepted data set are extracted according to the construction instruction, and the terrain information, spatial information and structural information in all the digital information elements are extracted; the terrain information, spatial information and structural information in all the digital information elements are extracted respectively to obtain a plurality of first property bodies, a plurality of second property bodies and a plurality of third property bodies, and the attribute values ​​of the first property body, the second property body and the third property body corresponding to each of the digital information elements are adjusted to obtain a plurality of target attribute values, and a corresponding fourth property body is obtained according to the plurality of target attribute values; a three-dimensional property body construction set is constructed according to all the first property bodies, all the second property bodies, all the third property bodies and all the fourth property bodies.

[0089] In the micro-environment platform, the construction instructions input by the user are obtained, and the intercepted data set is updated in multiple stages, including at least the planning stage (denoted as T1), the construction stage (denoted as T2), the registration and management stage (denoted as T3), and the operation and maintenance stage (denoted as T4). Figure 7 As shown, in the planning stage, by demarcating the land parcels on the CIM terrain or real 3D terrain surface, setting the use type of the land parcel, an open or closed property body (the first property body) is formed, which is recorded as ;like Figure 8 As shown in the figure, during the construction phase, a closed property body (second property body) is formed by extracting the spatial information of the BIM model, which is recorded as , spatial information extraction of BIM models can be directly obtained by reading different interfaces of BIM models; Fig. 9 As shown in the figure, in the registration and management stage, the characteristic corner points of various real estate units such as buildings, facilities, and natural resource types are identified on the real scene three-dimensional triangulated network structure to establish a closed property body (third property body), which is recorded as ;like Fig.10 As shown in the figure, during the operation and maintenance phase, , and The attribute value of is adjusted to obtain the fourth property right body, which is recorded as ; For the set of property rights constructed in the four stages, it is recorded as , Indicates the stage, Indicates the stage; digitally matching the "space" in the three-dimensional coordinate system and the "matter" in the digital coordinate system is conducive to improving the fit of the subsequent fusion of the three-dimensional coordinate system and the digital coordinate system, thereby improving the matching accuracy between "space" and "matter".

[0090] Step S30, construct a three-dimensional cadastral model, input the three-dimensional property body component set into the three-dimensional cadastral model, output a spatial data stream, add the spatial data stream to the unified window, obtain a second association relationship between all three-dimensional information elements and all digital information elements in the three-dimensional property body component set, and update the association set according to the second association relationship to obtain a target association set.

[0091] Specifically, a concept model, an event model and a process model are constructed, the three-dimensional property body component set is input into the concept model, a concept set is output, the concept set is input into the event model, a concept-key value set is output, the concept-key value set is input into the process model, and a spatial data stream is output; the spatial data stream is added to the unified window, and all three-dimensional information elements and all digital information elements in the spatial data stream are screened in the unified window. If any of the three-dimensional information elements is associated with any of the digital information elements, a second association relationship is generated, and the corresponding three-dimensional information element and the corresponding digital information element are added to the association set to obtain a target association set.

[0092] The 3D cadastral model includes: concept model, event model and process model. The process of constructing the 3D cadastral model mainly adopts the process modeling method, that is, the structure of "concept dictionary-event model-process model" is adopted, such as Fig.11 As shown, the left side is composed of a concept dictionary (concept model). The concept prototypes constructed by ontology rules are set in the dictionary, which have semantic non-repetitiveness, can improve the simplicity of the model output results, avoid repeated and redundant results, and thus improve the output efficiency; the middle is an event model, with information blocks as the core. The content in the information block is expressed in a "key-value" manner. The "key" value is mapped to the concept dictionary and has a unique identification number. At the same time, the content of the information block can be stored in the form of information sub-blocks. The structure of the information sub-block is consistent with the structure of the information block, which can effectively improve the accuracy of the results; the right side is a process model, which organizes event information into processes. A process cycle corresponds to at least one information block. The process cycle has a starting point (S) and an end point (E), and directed or undirected associations can be generated between process cycles.

[0093] Among them, the process of establishing a three-dimensional cadastral model can be based on land management business, as shown in Table 1.

[0094] Table 1: List of land management business events

[0095]

[0096] Furthermore, the three-dimensional property body component set is input into the model to embed the three-dimensional property body component set into the business flow model to form a spatial data flow, wherein each event in the three-dimensional cadastral model contains a corresponding information record (i.e., spatial data flow) , is a collection of key-value pairs. Represents the above "key-value", Any data type; traverse Collection, query when " "When , after the traversal is completed, the embedding of the data stream is realized.

[0097] Furthermore, the spatial data stream is added to the unified window, and the second association information between all three-dimensional information elements and all digital information elements in the spatial data stream is obtained, and the association set is updated accordingly. At the same time, the detection set also needs to be updated according to the second association information. , filter out the detection set There are associated objects in the system to achieve the fusion of property objects ("space" in the three-dimensional coordinate system) and material objects ("matter" in the digital coordinate system) with unified geographic reference, forming a digital twin scene of the three-dimensional property body, which solves the problem of mixed description and unclear expression of land space and material elements in traditional three-dimensional land management. At the same time, the digital twin scene of the three-dimensional property body is saved in the form of a three-dimensional model and used in the business flow of three-dimensional land management, which is more conducive to practical applications and provides users with a more convenient choice.

[0098] Step S40, analyzing the target association set to obtain a verified result, inputting the verified result into the constructed verification model, outputting a relationship verification result, a timing verification result and a subdivision relationship verification result, and if the relationship verification result, the timing verification result and the subdivision relationship verification result are all qualified, it is determined that the three-dimensional cadastral coordinate system and the digital coordinate system of the target detection area are successfully fused.

[0099] Specifically, the opposing relationships between all three-dimensional information elements and digital information elements in the target association set are analyzed to obtain a verified result; a verification model is constructed, and the verification model verifies the positional relationship between all three-dimensional information elements and digital information elements in the target association set according to the verified result, and outputs a relationship verification result; the verification model verifies the timing relationship between all three-dimensional information elements and digital information elements in the target association set according to the relationship verification result, and outputs a timing verification result; the verification model verifies the subdivision inclusion relationship between all three-dimensional information elements and digital information elements in the target association set according to the timing verification result, and outputs a subdivision relationship verification result; if the relationship verification result, the timing verification result and the subdivision relationship verification result are all qualified, it is determined that the three-dimensional cadastral coordinate system and the digital coordinate system of the target detection area are successfully fused.

[0100] Among them, after the digital twin scene of the three-dimensional property body is established, the updated target association set is input into the digital twin scene of the three-dimensional property body, and the existence relationship between the property object and the material object is verified to obtain the verification result. The existence relationship is based on the T1-T4 stage and to determine the existence status of The existence status is set to already exist , empty and planned , respectively representing the existence of the land space object, the non-existence of the object, and the future design existence of the object), as shown in Table 2.

[0101] Table 2: Existence relationship between material entities and three-dimensional property rights

[0102]

[0103] Furthermore, after obtaining the verification results, the position verification of the property object and the material object can be carried out. This process can use topological verification to obtain the relationship verification results, as shown in Table 3. The relationship verification results are qualified only if they meet the species topological relationship in the table.

[0104] Table 3: Topological relationship between material entities and three-dimensional property entities

[0105]

[0106] Furthermore, when the relationship verification result is qualified, the property object and material object corresponding to the relationship verification result are subjected to time sequence relationship verification. There are 7 types of time sequence relationship records, which represent the order in which the objects appear in the process, namely "before", "meet", "cover", "start", "in", "end" and "equal", such as Fig.12As shown. Cases beyond these conditions are recorded as unqualified cases. If they are these conditions, the timing verification result is qualified. Furthermore, when the timing verification result is qualified, the property object and material object corresponding to the timing verification result are subjected to a subdivision relationship verification, that is, to check whether each material object has a matching sub-property body. In particular, only when the three-dimensional property body is an object of a set of three-dimensional property body components (each cluster object is recorded as a sub-property body), a subdivision relationship verification is performed to obtain the corresponding subdivision relationship verification result. Otherwise, it is not performed. If there is a mismatch in the subdivision relationship verification, the verification fails. Furthermore, when the subdivision relationship verification result is qualified, it is determined that the three-dimensional cadastral coordinate system and the digital coordinate system of the target detection area are successfully integrated. In the process of verification, if any of the relationship verification result, the timing verification result or the subdivision relationship verification result fails the detection, it is necessary to return to the construction of the final spatial range. The process or manual intervention is used to correct the scene based on experience to ensure the consistency of space and material.

[0107] The present invention unifies the existing elements in the three-dimensional cadastral system and the digital twin platform by aligning multiple coordinate systems of the two systems, which can effectively avoid the neglect of material elements in the space, and at the same time achieve a good connection between the three-dimensional cadastral model and the digital platform, and perform multi-dimensional detection on the correlation relationship between the unified existing elements, which can effectively reduce the workload of the staff, ensure the consistency of space and material, and improve the matching accuracy between space and material.

[0108] Furthermore, if Fig.13 As shown, based on the above-mentioned fusion method of three-dimensional cadastral and digital twin platform, the present invention also provides a fusion system of three-dimensional cadastral and digital twin platform, wherein the fusion system of three-dimensional cadastral and digital twin platform includes:

[0110] The three-dimensional property body component set construction module 52 is used to define the first spatial range of the target detection area in the unified window, traverse all the three-dimensional information elements and all the digital information elements in the first spatial range to obtain a final spatial range, intercept multiple three-dimensional information elements and multiple digital information elements according to the final spatial range to obtain an intercepted data set, and import the intercepted data set into the constructed microenvironment platform for construction processing to obtain a three-dimensional property body component set;

Read multiple site information existing in the digital local coordinate system in the target detection area, associate all the site information with multiple three-dimensional information elements to obtain a centralized property object set, search for spatial information of a component of a centralized property object in the centralized property object set, match the spatial information with the corner point of the centralized property object to obtain a corner point translation, and translate the compensation information according to the corner point translation to align the three-dimensional component coordinate system and the digital component coordinate system to obtain a first association relationship between the three-dimensional cadastral coordinate system and the digital coordinate system; According to the first association relationship, a unified window is constructed, and all the three-dimensional information elements associated with any of the digital information elements are screened to construct an association set, and the association set is imported into the unified window; A three-dimensional property body component set construction module is used to define a first spatial range of the target detection area in the unified window, traverse all the three-dimensional information elements and all the digital information elements in the first spatial range to obtain a final spatial range, intercept multiple three-dimensional information elements and multiple digital information elements according to the final spatial range to obtain an intercepted data set, and import the intercepted data set into the constructed microenvironment platform for construction processing to obtain a three-dimensional property body component set; a target association set construction module, used for constructing a three-dimensional cadastral model, inputting the three-dimensional property body component set into the three-dimensional cadastral model, outputting a spatial data stream, adding the spatial data stream to the unified window, obtaining a second association relationship between all three-dimensional information elements and all digital information elements in the three-dimensional property body component set, and updating the association set according to the second association relationship to obtain a target association set; The fusion detection module is used to analyze the target association set to obtain a verified result, input the verified result into the constructed verification model, output a relationship verification result, a timing verification result and a subdivision relationship verification result. If the relationship verification result, the timing verification result and the subdivision relationship verification result are all qualified, it is determined that the three-dimensional cadastral coordinate system and the digital coordinate system of the target detection area are successfully fused.
