Specifically, the present embodiment provides:
The three-dimensional stratum interface construction method specifically comprises the following steps:
Step S10, receiving an actual stratum map input by a user in real time, and correcting the space position of a preset three-dimensional space according to coordinate information in the actual stratum map, wherein the actual stratum map comprises a plurality of contour lines and a plurality of geological boundaries;

Step S30, constructing a corresponding three-dimensional coordinate system according to the DEM surface and a plurality of geological boundaries based on a preset rule, and calculating inclination angles respectively corresponding to nodes in each geological boundary through the three-dimensional coordinate system;
And S40, acquiring the occurrence data corresponding to the nodes in each geological boundary in real time, and stretching the nodes of each geological boundary according to the occurrence data to generate a corresponding three-dimensional stratum interface.
Specifically, in this embodiment, first, as shown in fig. 2 to 4, in order to accurately construct a three-dimensional stratum interface corresponding to a certain area, it is necessary to receive, in real time, an actual stratum map that is drawn in advance by a user, where the actual stratum map includes information such as a required contour line and a geological boundary. Further, in order to create a three-dimensional stratum interface adapted to the size of the current actual stratum map, at this time, the preset three-dimensional space needs to be adjusted in real time according to the coordinate information contained in the current actual stratum map, that is, the spatial position of the current three-dimensional space is corrected in real time. Based on the above, a plurality of corresponding three-dimensional scattered points can be further converted in the adjusted three-dimensional space according to the acquired plurality of contour information, and meanwhile, in order to facilitate the generation of a subsequent three-dimensional coordinate system, at this time, a plurality of current three-dimensional scattered points are further required to be subjected to corresponding triangulation processing, and a required DEM (digital terrain model) surface is correspondingly constructed so as to facilitate the subsequent processing.
Further, after the required DEM surface is obtained in real time, at this time, the current DEM surface and the geological boundaries can be directly subjected to three-dimensional processing according to preset rules, and a required three-dimensional coordinate system can be generated, so that the inclination angle corresponding to the node in each geological boundary can be calculated in real time through the current three-dimensional coordinate system. On the basis, the occurrence data corresponding to the nodes in each geological boundary are synchronously acquired, and finally, the nodes of each geological boundary are stretched according to the current occurrence data, so that the needed three-dimensional stratum interface is finally generated. In addition, it should be noted that the occurrence data of each node may be obtained from the actual stratigraphic diagram, and the contour lines have elevation properties, while the geological boundary does not have elevation properties.
Second embodiment

and respectively projecting each target node onto the DEM surface to generate a corresponding three-dimensional geological boundary, and constructing the three-dimensional coordinate system according to the three-dimensional geological boundary, wherein each target node has uniqueness.
Specifically, in this embodiment, it should be noted that, in order to quickly and effectively construct a required three-dimensional coordinate system, after a plurality of required geological boundaries are obtained through the above steps, since each geological boundary is composed of a plurality of nodes, a plurality of initial nodes included in each geological boundary can be correspondingly extracted based on the geological boundary, and meanwhile, in order to prevent data leakage, encryption processing needs to be performed on each initial node, and a plurality of corresponding target nodes can be generated. Further, each target node is projected onto the DEM surface respectively, and a required three-dimensional geological boundary can be correspondingly generated, and meanwhile, a corresponding three-dimensional coordinate system is constructed according to the current three-dimensional geological boundary.
Further, since each target node is unique, the corresponding constructed three-dimensional geological boundary and the three-dimensional coordinate system are also unique, so that subsequent processing is facilitated.
Further, 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, matching a target triangle net corresponding to each target node in the DEM surface, and detecting an elevation value corresponding to each target triangle net in the DEM surface in real time;
and correspondingly assigning the elevation value to each target node to generate a corresponding three-dimensional node, and sequentially connecting each three-dimensional node to correspondingly generate the three-dimensional geological boundary.

Specifically, for ease of understanding, for example, P i (i=1, 2 … n) is acquired as a number of target nodes, where the target nodes have no elevation attribute. Further, after each elevation value is correspondingly assigned to each target node, each target node can have an elevation attribute, and a needed three-dimensional node can be generated. Specifically, for example, the obtained target nodes are:

| Nodes in the geological boundary A | x | y |
| P1 | 381234.8 | 3057860.6 |
| ··· | ··· | ··· |
| Pn | 383003.4 | 3058343.2 |
Wherein, table 1 shows two-dimensional coordinates of a plurality of target nodes, and further, after the elevation attribute is given, the three-dimensional nodes generated in real time may be:

From which each three-dimensional node has a corresponding three-dimensional coordinate, thereby enabling further generation of the desired three-dimensional geological boundary for subsequent processing.
Third embodiment
Further, the step of constructing the three-dimensional coordinate system according to the three-dimensional geological boundary includes:
When the three-dimensional geological boundary is obtained in real time, constructing piecewise functions corresponding to a plurality of nodes in the three-dimensional geological boundary one by one, and calculating trend corresponding to the nodes in the three-dimensional geological boundary through the piecewise functions;

And stretching the average trend along the z-axis direction to generate a corresponding z-L plane, and correspondingly constructing the three-dimensional coordinate system through the z-L plane, wherein the three-dimensional coordinate system has uniqueness.
In addition, in this embodiment, as shown in fig. 5 to 6, after the required three-dimensional geological boundary is obtained in real time through the above steps, in order to accurately construct a required three-dimensional coordinate system so as to correspondingly improve the accuracy of the constructed three-dimensional stratum interface, it is necessary to further create a corresponding piecewise function according to a plurality of nodes included in the three-dimensional geological boundary, and further calculate the trend corresponding to each node in the three-dimensional geological boundary through the piecewise function. It should be noted that, since the existing occurrence data specifically includes data such as trend, tendency, and dip angle, the difference between the trend and the tendency is 90 degrees. In addition, any curve can be fitted by one or more functions in the three-dimensional space, the tangent vector of the curve is the trend, the tangent vector can be obtained by deriving the piecewise function, and the normal vector of the corresponding curve is the trend.
Further, the piecewise function constructed in real time may be c=f (x, y, z), further, derivative is performed on the current piecewise function, the trend L of any node may be calculated by further substituting the three-dimensional coordinates of the nodes in the table 2 into the formula after derivative, and the calculated trend L may be added or subtracted by 90 degrees, so that the tendency of any node may be correspondingly obtained, and specifically, the calculated expression may be:
Wherein x, y, z represent three-dimensional coordinates, L represents trend, and M represents trend, so that trend and trend corresponding to each node can be effectively calculated, and subsequent processing is facilitated.
Further, the expression of the preset algorithm is:
Wherein, Representing the average trend, n represents the total number of nodes in the three-dimensional geological boundary, and L i represents the trend of each node (i=1, 2 … n).
In addition, in this embodiment, after the trend corresponding to each node is calculated in real time in the above manner, in order to further improve the accuracy of the three-dimensional stratum interface constructed, it is also necessary to further calculate the corresponding average trend. Based on the above, the preset algorithm is correspondingly called out, and the required average trend is calculated immediately through the preset algorithm, so that the subsequent processing is facilitated.

And calculating the inclination angles corresponding to the nodes in each geological boundary in real time through the reflection function, wherein the inclination angles are specific numerical values.
In this embodiment, as shown in fig. 7, after the required three-dimensional geological boundary is obtained through the above steps, the current three-dimensional geological boundary is further vertically projected into the z-L plane, and a mapped three-dimensional geological boundary is obtained, and corresponding three-dimensional coordinates are assigned to a plurality of nodes included in the current mapped three-dimensional geological boundary, and specifically, the three-dimensional coordinates generated in real time may be:

| Nodes in geological boundary A 2 | x | y | z |
| P1 | 383034.8 | 3058021.9 | 87.3 |
| ··· | ··· | ··· | ··· |
