Description

[0021] The names of the messages or information exchanged between the multiple devices in the embodiments of the present invention are for illustrative purposes only and are not intended to limit the scope of these messages or information.
[0022] In related technologies, many hydraulic structures in conventional hydropower, water conservancy, and pumped storage power station projects have complex and varied shapes. Taking the toe slab of a concrete-faced rockfill dam as an example, the toe slab line needs to be continuously adjusted in the early stages of design to adapt to the dam face, dam foundation, and other structures. The spatial distribution of the toe slab line has no obvious pattern and needs to be determined based on multiple factors such as topography and geology. However, during the modeling process, multiple control point coordinates are required for one toe slab line, and these control points are obtained through the intersection of straight lines. This makes it difficult to ensure that the final elevation coordinates of the toe slab line control points are obtained in integer form, causing difficulties for subsequent construction surveying.
[0023] To address the problems existing in the aforementioned related technologies, this embodiment provides a method, apparatus, and electronic device for generating toe plates based on CATIA software.
[0024] like Figure 1 As shown in the figure, an embodiment of the present invention provides a method for generating toe lines based on CATIA software, comprising: Step 110: Use CATIA software to extract the turning points of the sketch toe line to obtain a set of two-dimensional coordinate points.
[0025] Specifically, such as Figure 2 As shown, CATIA (Computer Aided Three-Dimensional Interactive Application) is an integrated CAD / CAE / CAM software. CATIA is renowned for its powerful surface modeling capabilities and sophisticated assembly management, covering not only drafting but also conceptual design, detailed design, and engineering analysis (CAE). CATIA software provides sketching tools, allowing users to create two-dimensional planar sketches, perform preliminary toe-plate line fitting to describe the sketch's toe-plate lines, extract turning points from the sketch's toe-plate lines, and obtain a set of two-dimensional coordinate points. Plane A is established using plane equations, defined by three points: A, B, and C. Point A is the left endpoint of the dam axis, point B is the right endpoint of the dam axis, and point C is any point on a plane oriented with the dam axis, dipping upstream at a fixed angle. A two-dimensional planar sketch is created on this plane A, and its abbreviation is defined as "ska".
[0026] Step 120: Perform coordinate transformation on the set of two-dimensional coordinate points to obtain a set of three-dimensional coordinate points, wherein the set of three-dimensional coordinate points includes multiple three-dimensional coordinate points located on a three-dimensional reference plane and their corresponding elevation coordinates.
[0027] Specifically, such as Figure 2As shown, based on the 2D planar sketch ska, a 3D reference plane xpln is established based on the 2D planar sketch. The 3D reference plane xpln is consistent with plane A. To ensure that the elements generated in subsequent steps are only related to the sketch, the 3D reference plane xpln needs to be re-established. Any point is extracted from the set of 2D coordinate points cn, and the 2D point is transformed into a 3D point pa: , Here, `point2dto3d()` is a function that converts a 2D point object into its corresponding 3D point, and `GetItem(m)` retrieves the m-th element from the collection `cn`. The elevation coordinates `paz` (length value) are extracted from the z-value representing elevation in the 3D point `pa(x, y, z)`. , Here, coord(3) calls the coord() function of the point object, and passes in the parameter 3, which means to get the third coordinate component, namely the Z-axis coordinate.
[0028] Step 130: Round each of the elevation coordinates according to the preset rounding precision to obtain the corresponding horizontal cross-sectional plane.
[0029] Specifically, such as Figure 2 As shown, each elevation coordinate is rounded according to a preset rounding precision to obtain the rounded elevation coordinate paaz. A horizontal cross-sectional plane plna is generated from all the rounded elevation coordinates paaz. This plna is parallel to the vectors of the xy plane, but not overlapping. The horizontal cross-sectional plane plna represents a plane parallel to the global horizontal reference plane and whose elevation is equal to the standard elevation value. The function for creating the horizontal cross-sectional plane plna includes: , Among them, planeoffset() is a function to create a new plane, and True is a boolean parameter.
[0030] Step 140: Correct the three-dimensional coordinate points using the three-dimensional reference plane and the horizontal cross-sectional plane to obtain the corrected three-dimensional coordinate points.
[0031] In some more specific embodiments, such as Figure 2 As shown, the horizontal cross-section plane *plan* intersects with the 3D reference plane *xpln* formed by the sketch, creating a spatial intersection line. The 3D coordinate point *pa* is projected onto this spatial intersection line, and the vertex *pa* on the 2D plane sketch *ska* is calculated to be the point *paa* closest to the intersection line. Point *paa* is then used as the corrected 3D coordinate point. Here, xy represents the horizontal plane in the coordinate system.
[0032] Step 150: Obtain the elevation rounding toe plate line using all the corrected three-dimensional coordinate points.
[0033] Specifically, extract one point from all the corrected 3D coordinate points and define it as pb. Then extract the next point and define it as pc. Connect the two points with a straight line. Repeat this process to form an elevation-rounded toe plate line.
[0034] In this embodiment, CATIA software is used to extract the turning points of the sketch toe slab line, obtaining a set of two-dimensional coordinate points. This allows for rapid response when the toe slab line needs adjustment due to changes in the foundation terrain. The sketch toe slab line is extracted to obtain a set of two-dimensional coordinate points. This set of two-dimensional coordinate points is automatically mapped to a three-dimensional reference plane, obtaining three-dimensional coordinate points and automatically associating them with corresponding elevation coordinates. By forcibly rounding the elevation coordinates to a preset precision, the generated toe slab line node elevations are all integer values, resulting in the corresponding horizontal cross-sectional plane, facilitating subsequent construction measurements. The corresponding three-dimensional coordinate points are corrected using the three-dimensional reference plane and the horizontal cross-sectional plane. Through geometric projection correction, the spatial position of the three-dimensional coordinate points remains smoothly transitioned after rounding. The toe slab line with rounded elevations is obtained from all corrected three-dimensional coordinate points, thereby improving the accuracy of toe slab line generation.
[0035] Optionally, the step of using CATIA software to extract the turning points of the sketch toe line to obtain a set of two-dimensional coordinate points includes: A two-dimensional planar sketch is obtained using the sketching tool of the CATIA software. The two-dimensional planar sketch includes the left endpoint of the dam axis, the right endpoint of the dam axis, and a third reference point. The third reference point is located on a plane that forms a fixed angle with the horizontal plane along the dam axis. The toe line of the sketch is obtained by performing preliminary toe line fitting on the two-dimensional planar sketch; The set of two-dimensional coordinate points is obtained by extracting the turning points of the toe line of the sketch.
[0036] Specifically, the third reference point is any point on a plane oriented with the dam axis, dipping upstream of the river, and with a fixed dip angle. A preliminary toe slab line (a polyline composed of straight lines) is sketched in the draft, ensuring it lies below the weakly weathered rock layer. All turning points in the toe slab line (ska) are extracted to form a set of coordinate points (cn). , In this context, Query() is the function to call the object, and 2DPoint is the two-dimensional coordinate point.
[0037] Optionally, the step of rounding each of the elevation coordinates according to a preset rounding precision to obtain the corresponding horizontal cross-sectional plane includes: Each of the elevation coordinates is rounded according to the preset rounding precision to obtain the rounded elevation coordinates; The rounded elevation coordinates include: , Where paaz is the rounded elevation coordinate, paz is the elevation coordinate, jd is the preset rounding precision, and int() is the rounding function; The horizontal cross-sectional plane is obtained by using all the rounded elevation coordinates.
[0038] In some more specific embodiments, jd is 0.1m or 0.5m. A horizontal cross-sectional plane plna is generated by rounding the elevation coordinates paaz, which is consistent with the vector of the xy plane. The function for establishing the horizontal cross-sectional plane plan includes: , Among them, planeoffset() is a function used for geometric modeling, which means that an actual horizontal cross-sectional plane is generated by offsetting according to the specified elevation value based on the xy coordinate plane. true is a boolean control parameter.
[0039] Optionally, the step of correcting the three-dimensional coordinate points using the three-dimensional reference plane and the horizontal cross-sectional plane to obtain corrected three-dimensional coordinate points includes: Based on the intersection function, a spatial intersection line is obtained through the three-dimensional reference plane and the horizontal cross-sectional plane; The three-dimensional coordinate points are projected onto the spatial intersection line to obtain the corrected three-dimensional coordinate points.
[0040] Specifically, to ensure that the elements generated in subsequent steps are only related to the sketch, the 3D reference plane xpln needs to be re-established, and the function is as follows: , Here, `plane()` represents a function that generates or retrieves the associated plane based on the input object. The spatial intersection line is obtained through the 3D reference plane `xpln` and the horizontal cross-section plane `plan`. The function `point-to-curve-nearest-point` is called, taking the 3D coordinate point `pa` as input and the spatial intersection line as the target, to calculate and return the point on the spatial intersection line with the shortest geometric distance to the 3D coordinate point, thus obtaining the corrected 3D coordinate point `pa`, including: , Among them, pointoncurve() is a function that finds the closest point on a curve and returns the projected point, intersect() is a function that calculates the intersection of two planes, and 0m is a tolerance parameter.
[0041] In this optional embodiment, the distance between the coordinates of the feature points and the elevations of the nearby integer coordinate points is detected. By controlling the tolerance between the two points, potential integer coordinate points are identified, and then the coordinates are converted into integer elevation spatial coordinate points smaller than the tolerance.
[0042] Optionally, obtaining the elevation-rounded toe line through all the corrected three-dimensional coordinate points includes: By sequentially arranging all the corrected 3D coordinate points, a set of corrected 3D points is obtained; By sequentially connecting adjacent corrected three-dimensional coordinate points in the corrected three-dimensional point set, multiple straight line segments are obtained; The elevation rounding toe plate line is obtained from all the said straight line segments.
[0043] Specifically, a loop counter is set up to sequentially extract the nth point from the modified 3D point set, defining it as the first endpoint, and the (n+1)th point as the second endpoint. A line construction function is called to connect the first endpoint and the second endpoint to generate a single straight line. This process is repeated until all adjacent point pairs in the set have been traversed. All generated single straight lines are then connected end-to-end to form a continuous polyline model.
[0044] In this optional embodiment, by establishing an ordered set of points, it is ensured that subsequent connection operations strictly follow the spatial orientation of the dam axis, thereby guaranteeing the geometric topological continuity and logical correctness of the generated toe plate line.
[0045] Optionally, obtaining the toe line of the sketch by performing preliminary toe line fitting on the two-dimensional planar sketch includes: Acquire dam cross-sectional image data; Feature extraction is performed on the dam cross-section image data to obtain discrete points of the toe plate line; The sketch toe plate line is obtained based on the discrete points of the toe plate line.
[0046] Specifically, image data of the dam cross-section is acquired. This image data originates from scanned copies of geological survey reports, orthophotos generated from on-site photogrammetry, or slice renderings of three-dimensional geological models. Image processing algorithms are used to extract features from the dam cross-section image data, identifying terrain contours and potential building structure boundaries, thereby calculating a set of discrete points representing the toe slab orientation. Finally, curve fitting algorithms (such as least squares or spline interpolation) are used to connect these discrete points, generating an initial polyline composed of straight line segments, i.e., the sketched toe slab line.
[0047] Optionally, after obtaining the sketch toe plate line based on the discrete points of the toe plate line, the method further includes: Based on image recognition algorithms, weakly weathered rock layers are obtained from the dam cross-section image data; When the sketch toe line is higher than the weakly weathered rock layer, return to the step of extracting features from the dam cross-section image data to obtain discrete points of the toe line.
[0048] Specifically, based on deep learning image recognition algorithms (such as convolutional neural networks CNN), the dam cross-section image data is analyzed again to automatically segment and extract the area of the weakly weathered rock layer and its upper interface contour. The generated sketch toe line is then spatially compared with the upper interface contour of the weakly weathered rock layer. If any part of the sketch toe line is detected to be located above the weakly weathered rock layer, the current fitting result is determined to not meet the geological constraints. A weight constraint factor is added, and the sketch toe line is regenerated until the generated sketch toe line is completely located below the weakly weathered rock layer.
[0049] In this optional embodiment, existing image data is directly parsed, key geometric features are automatically identified, and converted into a digitized discrete point sequence. This not only significantly shortens the preprocessing time from data collection to 3D modeling but also effectively avoids errors and ensures the accuracy of the initial data. When the sketch toe line is higher than the weakly weathered rock layer, the logical judgment of the feature extraction step is returned, establishing an automated negative feedback adjustment loop, which improves the accuracy of the sketch toe line generation.

The three-dimensional coordinate point correction module 40 is used to correct the three-dimensional coordinate points using the three-dimensional reference plane and the horizontal cross-sectional plane to obtain the corrected three-dimensional coordinate points.
