[0065] In order to more clearly understand the above-mentioned objectives, features and advantages of the present disclosure, the scheme of the present disclosure will be further described below. It should be noted that the embodiments of the present disclosure and the features in the embodiments can be combined with each other without conflict.

[0066] In the following description, many specific details are set forth to facilitate a full understanding of the present disclosure, but the present disclosure may also be implemented in other ways different from those described herein; it is obvious that the embodiments in the specification are only part of the embodiments of the present disclosure, rather than all of the embodiments.

[0067] Figure 1 1 is a flow chart of a method for three-dimensional modeling of a geological body provided by an embodiment of the present disclosure. This embodiment can be applied to the case of three-dimensional modeling of a geological body. The method of this embodiment can be executed by a three-dimensional modeling device for a geological body, which can be implemented in hardware and / or software and can be configured in a computer device. Figure 1 As shown, the method specifically includes the following:

[0068] S110, determining a plurality of geological objects corresponding to the geological body to be modeled.

[0069] The geological body to be modeled can be understood as a natural unit with a certain volume for which a model is to be established. The geological object can be understood as different types of objects included in the geological body to be modeled, such as rock mass, soil mass, water body, cavity body and other natural space geometric bodies.

[0070] To perform three-dimensional modeling on the geological body to be modeled, it is necessary to determine the various geological objects corresponding to the geological body to be modeled, so as to establish corresponding models for different geological objects.

[0071] S120, for each geological object among the multiple geological objects, determine a working area of ​​the current geological object, and establish a target model corresponding to the current geological object according to all surfaces included in the working area, wherein the working area includes a top surface, a bottom surface, and a side surface.

[0072] The working area can be understood as the different planes included in the geological object. Usually, the working area of ​​the geological object can include three types of planes, the top surface (also called the topographic surface when the geological object is exposed on the surface), the bottom surface (also called the modeling bottom interface) and the side surface. The side surface can be divided into the front side surface, the rear side surface, the left side surface and the right side surface. The target model can be understood as the three-dimensional model corresponding to the current geological object.

[0073] After determining the multiple geological objects corresponding to the geological body to be modeled, it is necessary to model each geological object separately. Specifically, each of the multiple geological objects can be taken as the current geological object in turn, and the working area of ​​the current geological object, that is, the top surface, bottom surface and side surface corresponding to the current geological object, is determined. Then all the surfaces contained in the working area are enclosed together, so that the target model corresponding to the current geological object can be established, thereby obtaining the target models corresponding to each geological object.

[0074] S130, synthesizing all target models according to the layering order corresponding to the geological body to be modeled, to obtain a three-dimensional model of the geological body to be modeled.

[0075] The layering order can be understood as the top-down order of geological objects corresponding to the geological body to be modeled. Various geological objects divide the geological body to be modeled into different layers.

[0076] After establishing the target models corresponding to each geological object, it is necessary to obtain the layering order of the various geological objects corresponding to the geological body to be modeled, and then synthesize all the target models according to the layering order to obtain the three-dimensional model of the geological body to be modeled. For example, assuming that the various geological objects corresponding to a geological body to be modeled are soil and rock, and the layering order is soil in the upper part and rock in the lower part, then according to the layering order of soil and rock, the target model corresponding to the soil and the target model corresponding to the rock are synthesized to obtain the three-dimensional model of the modeled geological body.

[0077] In this embodiment, multiple geological objects corresponding to the geological body to be modeled are first determined, and then for each of the multiple geological objects, the working area of ​​the current geological object is determined, and a target model corresponding to the current geological object is established according to all the faces contained in the working area, wherein the working area includes the top surface, the bottom surface and the side surface, and finally, according to the layering order corresponding to the geological body to be modeled, all the target models are synthesized to obtain a three-dimensional model of the geological body to be modeled. The above scheme can perform three-dimensional modeling on the geological body and improve the efficiency of three-dimensional modeling of the geological body.

[0078] In this embodiment, optionally, synthesizing all target models according to the layering order corresponding to the geological body to be modeled to obtain the three-dimensional model of the geological body to be modeled may specifically include:

[0079] According to the layering order corresponding to the geological body to be modeled, the spatial placement order corresponding to the target models is determined; the target models are synthesized according to the spatial placement order to obtain a three-dimensional model of the geological body to be modeled.

[0080] In this embodiment, according to the hierarchical order of the various geological objects corresponding to the geological body to be modeled, the spatial placement order corresponding to the target models can be determined, that is, the geological object at the bottom of the hierarchical order is placed first in the spatial placement order; the geological object at the top of the hierarchical order is placed last in the spatial placement order. The target model is synthesized according to the spatial placement order, and the three-dimensional model of the geological body to be modeled can be obtained. Through the above method, the three-dimensional model of the geological body to be modeled is more accurate, avoiding the failure in cutting and separating the "body" elements in the prior art.

[0081] In this embodiment, optionally, the determining of the multiple geological objects corresponding to the geological body to be modeled may specifically include:

[0082] Acquire geological survey data of the geological body to be modeled, wherein the geological survey data includes at least one of landmark geographic survey data, drilling data, geophysical data, geological plane data, geological profile data and stratigraphic contour line data; and determine a plurality of geological objects corresponding to the geological body to be modeled based on the geological survey data.

[0083] Among them, geological survey data can be understood as various data that can characterize the characteristics of geological bodies.

[0084] In this embodiment, the various geological objects determined by the above method are more accurate and closer to the actual situation, which is conducive to improving the accuracy of subsequent modeling.

[0085] Figure 2A 1 is a flow chart of a method for three-dimensional modeling of a geological body provided by an embodiment of the present disclosure. This embodiment is optimized on the basis of the above embodiment. Optionally, this embodiment provides a detailed explanation of the process of determining the target model corresponding to the current geological object.

[0086] like Figure 2A As shown, the method specifically includes the following:

[0087] S210, determining a plurality of geological objects corresponding to the geological body to be modeled.

[0088] S220 , for each of the multiple geological objects, divide the current geological object into different geological blocks according to the geological age and stratum lithology of the current geological object.

[0089] Among them, geological era can be understood as the era measured by geological methods, which can be divided into Archean, Proterozoic, Paleozoic, Mesozoic and Cenozoic. The era can be further subdivided into various levels such as era, epoch and period. Stratigraphic lithology can be understood as lithological stratigraphic units, which usually refer to stratigraphic bodies composed of rocks with uniform lithology, lithofacies or metamorphic degree.

[0090] The same geological object can be divided into different geological blocks according to its corresponding geological age and stratigraphic lithology. Therefore, for each of the multiple geological objects, the current geological object can be divided into different geological blocks according to its geological age and stratigraphic lithology, so as to subsequently establish a model corresponding to each geological block.

[0091] S230: for each geological block in the geological blocks, determine a first working area of ​​the current geological block, and establish a first model corresponding to the current geological block according to all surfaces included in the first working area.

[0092] The first model can be understood as a three-dimensional model corresponding to the current geological block.

[0093] For each geological block in different geological blocks, each geological block is taken as the current geological block in turn, and the first working area of ​​the current geological block is determined, that is: the top surface, bottom surface and side surface corresponding to the current geological block are determined, and then after the top surface, bottom surface and side surface corresponding to the current geological block are obtained, all the surfaces contained in the first working area are enclosed, and the first model corresponding to the current geological block can be obtained.

[0094] S240: Summarize all first models to obtain a first model set.

[0095] By aggregating the first models corresponding to each geological block in different geological blocks, a first model set can be obtained.

[0096] S250, synthesizing all first models included in the first model set according to the spatial position of each geological block to obtain a target model corresponding to the current geological object.

[0097] The spatial position of each geological block in the geological object to which it belongs is obtained, which can be specifically determined based on the geological survey data corresponding to the geological object. All first models included in the first model set are synthesized according to the spatial position of the geological block to obtain the target model corresponding to the current geological object.

[0098] S260, synthesizing all target models according to the layering order corresponding to the geological body to be modeled, to obtain a three-dimensional model of the geological body to be modeled.

[0099] In this embodiment, multiple geological objects corresponding to the geological body to be modeled are first determined, and then for each of the multiple geological objects, the current geological object is divided into different geological blocks according to the geological age and stratigraphic lithology of the current geological object. Then, for each of the geological blocks, the first working area of ​​the current geological block is determined, and a first model corresponding to the current geological block is established according to all the faces included in the first working area, all the first models are summarized to obtain a first model set, and all the first models included in the first model set are synthesized according to the spatial position of each geological block to obtain a target model corresponding to the current geological object. Finally, according to the layering order corresponding to the geological body to be modeled, all the target models are synthesized to obtain a three-dimensional model of the geological body to be modeled. In the above technical scheme, by dividing each geological object into different geological blocks, a three-dimensional model of each geological block is established, and then the three-dimensional models of all geological blocks are synthesized to obtain a target model of each geological object, so that the target model corresponding to the established geological object is more accurate and closer to the actual situation. Therefore, when all the target models are synthesized to obtain the three-dimensional model of the geological body to be modeled, the final three-dimensional model can be more closely matched with the geological body to be modeled. At the same time, the modeling method has good applicability and is suitable for various geological objects, and there is no need to cut and separate the "body" elements multiple times, which is conducive to improving work efficiency.

[0100] In this embodiment, optionally, for each geological block in the geological blocks, determining a first working area of ​​the current geological block, and establishing a first model corresponding to the current geological block according to all faces included in the first working area may specifically include:

[0101] For each geological block in the geological blocks, determine the top surface, bottom surface and side surface corresponding to the current geological block; enclose the collinear surfaces between the top surface and the side surface, and between the bottom surface and the side surface according to the collinearity requirement to obtain a first model corresponding to the current geological block.

[0102] In this embodiment, for each geological block in different geological blocks, the top surface, bottom surface and side surface corresponding to the current geological block are first determined, and then the collinear surfaces of the top surface and the side surface, and the bottom surface and the side surface are enclosed according to the collinearity requirement, so that the first model corresponding to the current geological block can be obtained. In the above method, the collinearity requirement of the geological block can be met, so that the established first model is more accurate.

[0103] In this embodiment, optionally, the method may further specifically include:

[0104] When at least one of the side surfaces corresponding to the current geological block pinches out, the pinched-out side surface is enclosed with the target surface according to the collinearity requirement, and the other side surfaces are enclosed with the corresponding top and bottom surfaces according to the collinearity requirement to obtain a first model corresponding to the current geological block, wherein the target surface is a surface that is collinear with the pinched-out side surface.

[0105] In this embodiment, if at least one of the side surfaces corresponding to the current geological block is pinched out, that is, the side surface becomes a "line", for this special case, the pinched-out side surface is enclosed with the target surface according to the colinearity requirement, and the other side surfaces are enclosed with the corresponding top and bottom surfaces according to the colinearity requirement to obtain the first model corresponding to the current geological block. This can avoid the failure of three-dimensional modeling of the geological block due to special circumstances, and is conducive to improving the accuracy and efficiency of the modeling process.

[0106] In this embodiment, optionally, synthesizing all first models included in the first model set according to the spatial position of each geological block to obtain the target model corresponding to the current geological object may specifically include:

[0107] Determine the coplanar first models in the first model set; synthesize the coplanar first models according to the spatial position of each geological block to obtain a target model corresponding to the current geological object.

[0108] Specifically, the coplanar first models in the first model set are first determined, and then the coplanar first models are synthesized according to the spatial position of each geological block, that is, the coplanar first models are placed together to obtain the target model corresponding to the current geological object.

[0109] For example, Figure 2B is a schematic diagram of the structure of various geological blocks corresponding to a geological object provided in an embodiment of the present disclosure, Figure 2C is a schematic diagram of a target model corresponding to a geological object provided in an embodiment of the present disclosure, Figure 2B and Figure 2C As an exemplary display.

[0110] like Figure 2B As shown, a certain geological object has 4 geological blocks, represented by 1, 2, 3 and 4 respectively, among which 1 and 2 have the same geological age but different stratigraphic lithology, 3 and 4 have the same geological age but different stratigraphic lithology, 1 and 3 have both different geological ages and stratigraphic lithology, 1 and 4 have both different geological ages and stratigraphic lithology, 2 and 3 have both different geological ages and stratigraphic lithology, and 2 and 4 have both different geological ages and stratigraphic lithology.

[0111] like Figure 2CAs shown, the bottom surface of 1 is used together with the top surface of 4, the bottom surface of 2 is used together with the top surface of 4, and the bottom surface of 3 is used together with the top surface of 4, that is, the coplanar first models include: the model corresponding to 1 and the model corresponding to 4, the model corresponding to 2 and the model corresponding to 4, and the model corresponding to 3 and the model corresponding to 4. According to the spatial positions of 1, 2, 3 and 4, the model corresponding to 1 is placed above the model corresponding to 4, the model corresponding to 2 is placed above the model corresponding to 4, and the model corresponding to 3 is placed above the model corresponding to 4, and the target model corresponding to the geological object is obtained.
