Foreign three-dimensional geologic modeling began in the 70 s of the 20 th century, and three-dimensional geologic modeling systems based on three-dimensional wire frame models (3D wire frames), i.e., "3D spatial information systems", were first developed. The system applies the three-dimensional modeling technology to the field of the earth mine for the first time, and has relatively simple realized functions and limited capability. Even so, this system has an irreplaceable, pioneering significance. The university of Nancy, j.l.mallet, teaches a "discrete smooth interpolation method" to interpolate physical properties and spatial locations, uses connections between nodes to simulate topological relationships, and its lead team uses this structure innovation for geologic bodies to apply it to the gorcad three-dimensional geologic modeling software. Ekoule proposes a solution to the reconstruction of non-convex profile three-dimensional objects. With the summary of technological efforts of the preknock man, canadian scholars Houlding first proposed the concept of three-dimensional geomodeling (3D Geoscience modeling) in 1994. This also means that the development of three-dimensional geologic modeling is beginning to advance toward integration. Recently Calcagno et al have proposed a new method of building geologic models using geologic interface location and formation site orientation data. Caumon et al propose a three-dimensional implicit modeling method of a stratigraphic model based on remote sensing data and tetrahedral meshes that allows expert knowledge and other ancillary up-and-down data to be integrated into the construction of the model. Vollgger et al propose a deposit formation analysis and evaluation method that combines three-dimensional implicit modeling and in-situ observation modeling based on large drilling data sets.And a vector potential field method is provided from the machine learning perspective, and a potential field model is regarded as a multi-category classification problem, so that implicit geological modeling is realized. To this end, some three-dimensional geologic modeling software has been developed abroad: goCAD, petrel, mineSight, micro Lynx, earth Vision, dataMine, vulcan, micromine, surpac, rock Ware, etc., but these modeling methods and modeling software have difficulty in dynamic updating of complex geologic bodies. The domestic three-dimensional geologic modeling research starts in the 90 s of the 20 th century, and in terms of three-dimensional geologic information systems, china universities (Wuhan) Wu Chonglong, tian Yiping, mao Xiao are equal, and a series of three-dimensional modeling technical methods and software systems for practical problems in various application fields of geology are provided for the problems of three-dimensional stratum trellis modeling of oil reservoirs, ore body modeling and reserve calculation, three-dimensional modeling of disaster bodies, urban underground space modeling and design and the like. The national academy of sciences Zhang Juming, et al developed a three-dimensional visualization system for geological information of slope engineering. Wu Lixin et al propose a Generalized Triangular Prism (GTP) model, and on the basis, build a three-dimensional geological modeling architecture oriented to mineral resource development and application. He Zhenwen through the research on the integrated data structure model of the three-dimensional geological space, a technical framework of three-dimensional dynamic modeling of the geological space is proposed. Chen Shuming et al put forward the generic weight algorithm theory and set up the three-dimensional digitization of engineering geologic model with IDL as the development platform. The university of Tianjin Zhong Denghua and the like develop a three-dimensional modeling and analysis system for the geology of the hydraulic and hydroelectric engineering based on OpenGL and OpenNURBS. Weng Zhengping further discusses a three-dimensional model rapid construction method of the complex geologic body, and provides a corresponding solution strategy for local dynamic update of the model. Tang Bingyin on the basis of a new mixed data model, the urban sedimentary facies modeling practice was developed. Chen Qiyu et al propose a knowledge-driven multi-scale three-dimensional geologic body model rapid construction method. Sun Zhenming, mao Shanjun and the like research key technologies such as plane-section corresponding algorithm, expansion search algorithm, spline surface algorithm, smooth transition algorithm and the like, and realize local dynamic correction of the three-dimensional model. Wang Tieli provides a method for rapidly and dynamically updating a surface mine topography and geology integrated entity model based on local updating in an expanded boundary aiming at the characteristics of surface mining. Yang Meng achieve the update purpose by replacing the face of the update scope. Yan Dafa adopts a two-dimensional and three-dimensional integrated linkage editing mode to well realize manual interactive updating. Li Zhanglin et al propose a dynamic model modeling method of ore bodies in the context of geoscience big data. Three-dimensional geologic modeling software developed domestically up to this point has QuantyView (original GeoView), mapGISK, visual Geo, creatar, DIMINE, 3DMine, minexplorer, and the like.
Despite the great development of three-dimensional geologic body modeling, some researchers have tried to study dynamic update of geologic bodies, but there are still many problems to be studied in depth, such as: some researches aim at updating single geological entities, and the correctness of the topological relation among the geological entities cannot be ensured; some researches are that the geometrical surface is updated by replacing and connecting a part of the surface, and the updating mode is difficult to maintain the topology between the layers, so that the multi-layer model is difficult to update; some scholars' designs are updated in an interactive mode, the degree of automation is not high, the efficiency is low, and the dynamic requirements are not met. Sometimes, the whole model must be pushed over to be totally reconstructed, and local dynamic update cannot be realized.

The method for dynamically updating the local part of the three-dimensional geologic body model based on knowledge-graph reasoning provided by the embodiment of the invention is described in detail below with reference to the accompanying drawings.
The embodiment of the invention discloses a three-dimensional geologic body model local dynamic updating method based on knowledge graph reasoning, which comprises the following operations:
s101, dividing an update area for an original geologic body model according to new geological exploration data, integrating all geometric entities in the update area, and converting the geometric entities into an adjacent entity integration model;
s102, deducing the update type caused by the influence of new geological exploration data in an update area through geological knowledge graph reasoning, wherein the update type comprises no topological change, stratum increase and stratum decrease;
s103, adopting different update strategies to finish local dynamic update aiming at different update types;
s104, converting the adjacent entity integration model into a layer model and constructing the layer model, and finishing updating of the geometric shape and the topological relation of the layer model to realize local dynamic updating of the three-dimensional geologic body model.
The embodiment of the invention creatively provides a model capable of automatically keeping the correctness of the topological relation between adjacent geological entities in the updating process, namely an adjacent entity integration model. The model integrates adjacent geological entities, so that the adjacent geological entities can be updated simultaneously in the updating process, and the topological relation among the geological entities is ensured to be unchanged.
And acquiring an original geologic body model needing local dynamic update, and performing data preprocessing so as to integrate the three-dimensional geologic body model into an adjacent entity integrated model. The data preprocessing process is as follows:
And loading new geological exploration data, including local new drilling, profile and other data, dividing an updating area according to the position information of the new and old geological original data in the three-dimensional space, integrating all geometric entities in the updating area, and converting the geometric entities into an adjacent entity integration model. In the preprocessing process, two principles of comprehensiveness of drilling information and uniformity of drilling space distribution are required to be followed when drilling is selected, projection is carried out according to orifice coordinates and stratum layering properties after drilling is selected, and then the input section is selected and projected.
The data structure of the adjacent entity integration model is shown in fig. 1, and the data structure comprises a point object, a data field and a topology field, wherein the point object comprises point coordinates and a polyhedron ID list Polyhedron ID List field, the data field stores object data, and the topology field stores a topological relation.
After integrating the three-dimensional geologic body model into an adjacent entity integrated model, loading data for updating the three-dimensional geologic body model, and deducing an updating type through a geologic knowledge map. In the knowledge graph, the nodes represent the entity and the edges represent the relationship, and under the application scene, the entity can be used for representing the stratum, and the relationship describes the contact relationship among different strata. Knowledge maps can be logically divided into concept relationship maps and entity relationship maps. The concept relation map expresses verified knowledge, contains definite concepts and association relations among the concepts, and can express axioms such as upper and lower layer contact relations of a stratum; the entity relation map also comprises entities and relations thereof, and the change between the new geological exploration data and the stratum sequence obtained by interpolation in the construction of the original model can be deduced through the inquiry of the topological relation among stratum entities in the entity relation map, so that the update type belongs to the type without topological change, increasing stratum or reducing stratum.
For different update types, including no topology change, increasing stratigraphic layer or decreasing stratigraphic layer types, different update policies are employed for updating.
For the update type without topological change, no topological change occurs between new and old exploration data, the stratum existing in the new and added exploration data corresponds to the stratum in the old exploration data, but the spatial positions of the top and bottom of the stratum in the exploration data are changed, and the dynamic update steps are as follows:
S201, adding intersection points/intersecting lines of straight lines/planes of the newly added holes/sections and the geological entity into a data field and a topological field of the geological entity, so that newly added geological original data can participate in an updating process. When the intersection point/intersection line is added, the data fields between the adjacent surfaces of two adjacent geological entities are required to be kept the same, and the topological fields keep the normal directions of the surface patches opposite, so that the unreasonable conditions such as overlapping and hollowness between the two geological entities are prevented, and therefore, the topological fields of the two adjacent geological entities are required to be added simultaneously when the intersection point is added;
s202, calculating the relative distance between the straight line/plane of the drilling/section and the intersection point/intersecting line of the stratum layer top and layer bottom in the direction of the drilling/section in the newly added drilling/section;
S203, traversing all triangle surfaces in the geological entity, and finding out the upper and lower surfaces of the stratum through the normal line of the triangle surfaces;
S204, adopting an interpolation motion vector method, selecting a spatial interpolation algorithm, a Criger or inverse distance power method and the like, respectively carrying out spatial interpolation on each vertex in an updating area in a geological entity, calculating the distance which should move along the direction of a drilling hole/a profile and moving, wherein the vertex on the upper surface of a stratum is interpolated according to the distance that a straight line/a plane where the drilling hole/the profile is located and an intersection point/an intersection line of the top of the stratum are moved in the newly added drilling hole/the profile; the vertex on the lower surface of the stratum is interpolated according to the moving distance between the straight line/plane of the drilling hole/section and the intersection point/intersection line of the stratum bottom in the newly added drilling hole/section; the points on both the upper and lower surfaces remain stationary. Since the models between different strata have been integrated, when one vertex is moved, entities sharing that vertex remain in an abutting relationship.
For increasing the stratum update type, increasing the stratum refers to that compared with the original stratum sequence, stratum which does not exist before exists in the stratum sequence of the newly added exploration data, the situation that the change occurs is early in pinch out, lens bodies are added, and the like, and the two situations can be updated through the following dynamic update algorithm, wherein the specific dynamic update steps are as follows:
S301, finding upper and lower adjacent strata of the newly added stratum according to stratum sequences in the newly added geological exploration data;
s302, respectively updating the lower/upper surfaces of the upper and lower adjacent strata according to an updating algorithm without topological change, searching geological entities sharing the point through Polyhedron ID List fields of the vertexes in a data domain of the integrated model when the vertexes are moved in the S204 step of the updating algorithm without topological change, and if the geological entities are shared with the newly added strata, normally moving; if the two adjacent strata are shared with the other upper and lower adjacent strata of the newly added stratum, the two adjacent strata are moved in a cracking way, and the reverse topology of the triangle surface where the vertex is located in the topology domain is recorded; if the water-logging agent is shared with other stratum, the water-logging agent is kept still;
S303, if in the step S302, when the situation that the vertex shared by the geological entity representing the newly added stratum exists in the updating process of the upper and lower adjacent strata of the newly added stratum, the situation that the pinch-out is too early is corresponding, adding the reverse topology recorded in the step S302 into the topology domain representing the geological entity of the newly added stratum; if there is no vertex shared with the geological entity representing the newly added stratum, and the lens is needed to be added, the reverse topology recorded in step S302 is combined to create a geological entity, and the Polyhedron ID List fields of the vertices in the integrated model are maintained.
For reducing the stratum update type, the stratum reduction means that compared with the original stratum sequence, the stratum sequence of newly added geological exploration data reduces the stratum existing before, the situation that the change occurs is too late in pinch out, the stratum has holes and the like, and the two situations can be updated through the following dynamic update algorithm, wherein the specific dynamic update steps are as follows:
s401, constructing the upper and lower surfaces of the reduced stratum by using all geological exploration data including original data and newly added data in an updating area;
S402, performing Boolean shearing on the reduced stratum by using the upper surface and the lower surface constructed in the S401 respectively;
s403, combining the sheared parts of the upper surface and the lower surface in the step S402 with the upper adjacent stratum and the lower adjacent stratum respectively through Boolean operation.
And converting the adjacent entity integration model back to the updated layer model to finish the updating of the geometric shape and the topological relation of the layer model, thereby realizing the synchronous updating of the layer surface, the construction surface and the topological relation of the geological body.
As shown in fig. 2, in the embodiment of the present invention, a QuantyView platform is taken as an example, and local dynamic update is performed on a three-dimensional geologic body model:
S501, inputting a geological exploration data set of a certain modeling area;
S502, projecting geological exploration data into a three-dimensional scene;
s503, dividing an updating area according to the position information of the new geological exploration data and the old geological exploration data in the three-dimensional space;
S504, integrating all original geometric entities in the updated area, and converting the original geometric entities into an adjacent entity integration model;
S505, reasoning out the update type of the local dynamic update by using the geological knowledge map;
S506, updating geometric, topological and semantic relations by adopting different dynamic updating strategies according to three different updating types of no topological change, increased stratum and reduced stratum by adopting an interpolation vector method;
S507, repeating the steps S501-S506 to finish updating all new exploration data;
s508, converting the adjacent entity integration model back to the updated layer model, and finishing updating the geometric shape and the topological relation of the layer model, thereby realizing synchronous updating of the layer surface, the construction surface and the topological relation of the geological body.
