Description

A three-dimensional stratum interface construction method and system

Technical Field

The present invention relates to the field of geological technology, and in particular to a three-dimensional stratum interface construction method and system.

Background technique

With the advancement of science and technology and the rapid development of productivity, computer technology has become mature and has been deeply applied in many fields, improving people's work efficiency.

Among them, computer technology has also been widely used in the field of geological research. Specifically, in existing geological research, in order to understand the geological conditions of a certain area, the corresponding three-dimensional stratigraphic interface is constructed through the acquired regional geological data, so that the distribution of the strata can be observed intuitively.

Based on this, most of the existing technologies will complete the construction of three-dimensional stratigraphic interfaces through existing map section modeling, direct geological map modeling, and digital geological mapping route modeling. However, the above modeling methods are heavily dependent on the acquired occurrence data, so that the quantity and accuracy of the occurrence data directly determine the accuracy of the three-dimensional stratigraphic interface. However, because the occurrence data is mainly obtained through field measurements, the occurrence data measured in the field are usually limited, which leads to low accuracy of the constructed three-dimensional stratigraphic interface, which correspondingly reduces work efficiency.

Summary of the invention

Based on this, the purpose of the present invention is to provide a three-dimensional stratigraphic interface construction method and system to solve the problem that the prior art relies heavily on occurrence data to construct the corresponding three-dimensional stratigraphic interface, resulting in low accuracy of the constructed three-dimensional stratigraphic interface.

Based on this, in order to simulate the corresponding three-dimensional stratigraphic interface, it is necessary to adjust the spatial position of the preset three-dimensional control, that is, the corresponding spatial coordinates, in real time according to the coordinate information contained in the current actual stratigraphic map.

Please refer to Figure 1, which shows a three-dimensional stratigraphic interface construction method provided in the first embodiment of the present invention. The three-dimensional stratigraphic interface construction method provided in this embodiment can greatly reduce the dependence on occurrence data, correspondingly improve work efficiency, and at the same time improve the user experience.

Specifically, this embodiment provides:

A three-dimensional stratum interface construction method specifically comprises the following steps:

Step S10, receiving an actual stratigraphic map input by a user in real time, and correcting the spatial position of a preset three-dimensional space according to coordinate information in the actual stratigraphic map, wherein the actual stratigraphic map includes a plurality of contour lines and a plurality of geological boundaries;

Step S20, converting the plurality of contour lines into a plurality of corresponding three-dimensional scattered points in the preset three-dimensional space, and performing triangulation processing on the plurality of three-dimensional scattered points to construct a corresponding DEM surface;

Step S30, constructing a corresponding three-dimensional coordinate system according to the DEM surface and the plurality of geological boundaries based on a preset rule, and calculating the inclination angle corresponding to each node in the geological boundary through the three-dimensional coordinate system;

Step S40, acquiring the occurrence data corresponding to each node in the geological boundary in real time, and stretching each node of the geological boundary according to the occurrence data to generate a corresponding three-dimensional stratigraphic interface.

Specifically, in this embodiment, it should be noted that, as shown in Figures 2 to 4, in order to accurately construct a three-dimensional stratigraphic interface corresponding to a certain area, it is necessary to receive in real time the actual stratigraphic map drawn in advance by the user. Specifically, the actual stratigraphic map contains the required contour lines and geological boundaries and other information. Further, in order to create a three-dimensional stratigraphic interface that is adapted to the size of the current actual stratigraphic map, it is also necessary to adjust the position of the pre-set three-dimensional space in real time according to the coordinate information contained in the current actual stratigraphic map, that is, to correct the spatial position of the current three-dimensional space in real time. Based on this, it is possible to further convert the corresponding three-dimensional scattered points in the adjusted three-dimensional space according to the obtained contour line information. At the same time, in order to facilitate the generation of the subsequent three-dimensional coordinate system, it is also necessary to further perform corresponding triangulation processing on the current three-dimensional scattered points and construct the required DEM (digital terrain model) surface accordingly, so as to facilitate subsequent processing.

Furthermore, after obtaining the required DEM surface in real time, the current DEM surface and the above-mentioned several geological boundaries can be directly processed in three dimensions according to the pre-set rules, and the required three-dimensional coordinate system can be generated. Based on this, the inclination corresponding to the node in each geological boundary can be calculated in real time through the current three-dimensional coordinate system. On this basis, the occurrence data corresponding to the node in each geological boundary is obtained synchronously, and finally the node of each geological boundary is stretched according to the current occurrence data to finally generate the required three-dimensional stratigraphic interface. In addition, it should be noted that the occurrence data of each node can be obtained from the above-mentioned actual stratigraphic map, and the above-mentioned contour lines have elevation attributes, while the geological boundaries do not have elevation attributes.

Second embodiment

Furthermore, the step of constructing a corresponding three-dimensional coordinate system according to the DEM surface and the plurality of geological boundaries based on preset rules includes:

When a plurality of geological boundaries are acquired in real time, a plurality of initial nodes contained in each of the geological boundaries are extracted in real time, and encryption processing is performed on the plurality of initial nodes to generate a plurality of corresponding target nodes;

Each of the target nodes is projected onto the DEM surface to generate a corresponding three-dimensional geological boundary, and the three-dimensional coordinate system is constructed according to the three-dimensional geological boundary. Each of the target nodes is unique.

Specifically, in this embodiment, it should be noted that in order to quickly and effectively construct the required three-dimensional coordinate system, after obtaining several required geological boundaries through the above steps, since each geological boundary is composed of several nodes, based on this, several initial nodes contained in each geological boundary can be correspondingly extracted. At the same time, in order to prevent data leakage, each initial node needs to be encrypted at this time, and several corresponding target nodes can be generated. Further, each target node is projected onto the above DEM surface, and the required three-dimensional geological boundary can be generated accordingly. At the same time, the corresponding three-dimensional coordinate system is constructed according to the current three-dimensional geological boundary.

Furthermore, since each target node is unique, the corresponding constructed three-dimensional geological boundary and three-dimensional coordinate system are also unique, which facilitates subsequent processing.

Furthermore, the step of projecting each of the target nodes onto the DEM surface to generate a corresponding three-dimensional geological boundary includes:

Based on a preset direction, a target triangulated network corresponding to each of the target nodes is matched in the DEM surface, and an elevation value corresponding to each of the target triangulated networks is detected in real time in the DEM surface;

The elevation value is assigned to each of the target nodes to generate a corresponding three-dimensional node, and each of the three-dimensional nodes is connected in sequence to generate the three-dimensional geological boundary.

Specifically, in this embodiment, it should be noted that after the required DEM surface is obtained through the above steps, the target triangulated network corresponding to each target node is further matched in real time in the vertical direction. At the same time, the elevation value corresponding to each target triangulated network is synchronously detected, and each elevation value is assigned to each target node accordingly, so that each target node can be assigned a corresponding three-dimensional coordinate to generate a corresponding three-dimensional node. Based on this, it is only necessary to connect several current three-dimensional nodes in sequence to generate the above three-dimensional geological boundary. Specifically, for ease of understanding, for example, the several target nodes obtained are _Pi (i=1, 2...n), and the target nodes at this time have no elevation attributes. Further, after each elevation value is assigned to each target node, each target node can have an elevation attribute and generate the required three-dimensional nodes. Specifically, for example, the several target nodes obtained are:

Table 1

The nodes in the geological boundary A x y P ₁ 381234.8 3057860.6 ··· ··· ··· P _n 383003.4 3058343.2

Table 1 shows the two-dimensional coordinates of several target nodes. Furthermore, after being assigned elevation attributes, the three-dimensional nodes generated in real time can be:

Table 2

It can be seen that each 3D node has a corresponding 3D coordinate, so that the required 3D geological boundary can be further generated to facilitate subsequent processing.

Third embodiment

Furthermore, the step of constructing the three-dimensional coordinate system according to the three-dimensional geological boundary includes:

When the three-dimensional geological boundary is acquired in real time, piecewise functions corresponding to several nodes in the three-dimensional geological boundary are constructed one by one, and the trends corresponding to the nodes in the three-dimensional geological boundary are calculated respectively by the piecewise functions;

When the trend is obtained in real time, a preset algorithm is called in real time, and the average trend corresponding to a number of nodes in the three-dimensional geological boundary is calculated in real time by the preset algorithm;

The average trend is stretched along the z-axis direction to generate a corresponding z-L plane, and the three-dimensional coordinate system is constructed through the z-L plane. The three-dimensional coordinate system is unique.

In addition, in this embodiment, it should be noted that, as shown in Figures 5 and 6, after the required three-dimensional geological boundary is obtained in real time through the above steps, in order to accurately construct the required three-dimensional coordinate system to correspondingly improve the accuracy of the constructed three-dimensional stratigraphic interface, it is necessary to further create a corresponding piecewise function based on the several nodes contained in the above three-dimensional geological boundary, and further calculate the strike corresponding to each node in the three-dimensional geological boundary through the piecewise function. Among them, it should be noted that the existing occurrence data specifically includes data such as strike, dip and dip, and the strike and dip differ by 90 degrees. In addition, in three-dimensional space, any curve can be fitted by one or more functions, and the tangent vector of the curve is the strike, which can be obtained by derivation of the piecewise function, and correspondingly, the normal vector of the curve is the dip.

Furthermore, the piecewise function constructed in real time may be C=f(x, y, z). Furthermore, the current piecewise function is derived, and the three-dimensional coordinates of the nodes in Table 2 are further substituted into the derived formula to calculate the direction L of any node, and the calculated direction L is added or subtracted by 90 degrees to obtain the inclination of any node. Specifically, the calculation expression may be:

Among them, x, y, z represent three-dimensional coordinates, L represents the direction, and M represents the inclination, so that the direction and inclination corresponding to each node can be effectively calculated to facilitate subsequent processing.

Furthermore, the expression of the preset algorithm is:

in, represents the average trend, n represents the total number of nodes in the three-dimensional geological boundary, and _Li represents the trend of each node (i=1, 2...n).

In addition, in this embodiment, it should be noted that after the direction corresponding to each node is calculated in real time in the above manner, in order to further improve the accuracy of the constructed three-dimensional stratigraphic interface, the corresponding average direction needs to be further calculated. Based on this, the above preset algorithm will be called up accordingly, and the required average direction will be calculated immediately by the preset algorithm for subsequent processing.

Fourth embodiment

Furthermore, the step of calculating the inclination angle corresponding to each node in the geological boundary through the three-dimensional coordinate system includes:

When the three-dimensional coordinate system is acquired in real time, a corresponding three-dimensional piecewise linear function is constructed based on the three-dimensional coordinate system, and a corresponding inverse mapping function is constructed based on the three-dimensional piecewise linear function in real time;

The inclination angle corresponding to each node in the geological boundary is calculated in real time through the inverse mapping function, and the inclination angle is a specific numerical value.

Among them, in this embodiment, it should be pointed out that, as shown in FIG7, after the required three-dimensional geological boundary is obtained through the above steps, the current three-dimensional geological boundary will be further vertically projected into the above z-L plane, and the mapped three-dimensional geological boundary will be obtained. Similarly, the corresponding three-dimensional coordinates are assigned to several nodes included in the current mapped three-dimensional geological boundary. Specifically, the three-dimensional coordinates generated in real time can be:

table 3

Nodes in geological boundary _A2 x y z P ₁ 383034.8 3058021.9 87.3 ··· ··· ··· ··· P _n 381225.7 3057457.8 87.7

Furthermore, after the required three-dimensional coordinate system is constructed by the above three-dimensional geological boundaries and the mapped three-dimensional geological boundaries, it is necessary to further generate the required three-dimensional piecewise linear function according to the current three-dimensional coordinate system, and simultaneously construct the required inverse mapping function according to the current three-dimensional piecewise linear function, wherein the expression of the three-dimensional piecewise linear function is:

Wherein, β represents the inclination angle, L represents the direction, and z represents the elevation. In addition, the current three-dimensional piecewise linear function can be vertically projected onto the above z-L plane to further obtain a two-dimensional piecewise linear function. Specifically, the expression of the two-dimensional piecewise linear function can be:

Similarly, L represents the direction and z represents the elevation. Based on this, the above method can be used to calculate the inclination angle corresponding to each node in each three-dimensional geological boundary, so as to facilitate subsequent processing.

Furthermore, the method further comprises:

When the three-dimensional stratigraphic interface is acquired in real time, the three-dimensional stratigraphic interface is subjected to graphic rendering processing based on a preset program to generate a corresponding color three-dimensional stratigraphic interface;

The colored three-dimensional stratum interface is displayed in real time on the user's display terminal.

Among them, in this embodiment, it should be pointed out that after the required three-dimensional stratigraphic interface is finally obtained through the above method, in order to enable the user to clearly observe the various components of the current three-dimensional stratigraphic interface, the current three-dimensional stratigraphic interface will be further subjected to graphic rendering processing through a pre-set rendering program, and a corresponding colored three-dimensional stratigraphic boundary will be generated. Preferably, the corresponding rendering can be performed through the existing UG software.

Furthermore, the rendered color three-dimensional stratum interface is displayed in real time on the user's display terminal to improve the user's work efficiency.
