Detailed Description
For the purpose of making the objects, technical solutions and advantages of the embodiments of the present invention more apparent, the technical solutions of the present invention will be clearly and completely described in conjunction with the embodiments, and it is apparent that the described embodiments are some embodiments of the present invention, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
The excavation of side slopes is an important work in the arrangement and design of hydraulic buildings, and is closely related to the topography and geology. The existing design of excavating and releasing slopes is often realized through drawing software modeling, but the operation related to the mode is very tedious, the operation requirement on a designer is high, and a large number of manual operations can severely restrict the efficiency of the design of excavating and releasing slopes, so that the problem becomes more serious under the condition of complex foundation planes.
Based on the method, the device and the electronic equipment for three-dimensional modeling of the hydraulic building excavation and slope release provided by the embodiment of the invention, the efficiency of the excavation and slope release design can be improved.
For the understanding of this embodiment, a three-dimensional modeling method for excavating and releasing a slope of a hydraulic building disclosed in the embodiment of the present invention is described in detail, and referring to fig. 1, the method may include the following steps:
Step S102, slope setting parameters and base surface side lines of the hydraulic building are respectively obtained.
The slope setting parameters may include a width of the catwalk, an elevation of the catwalk at each level, and a slope ratio between the catwalks at each level, and the base side line may include a first base side line located on an upstream side of the hydraulic building and a second base side line located on a downstream side of the hydraulic building.
For example, the elevation of each level of the horse road of the slope to be put, the slope ratio of the corresponding slope between each level of the horse road, and the width of the slope horse road line (i.e., the width of the horse road) may be obtained by a direct input method or a direct call of the existing data, and the base surface side line may be obtained by a real-time drawing method or a direct selection of the existing data by the user, which is not limited. Referring to fig. 2, two base side lines (which are all multi-segment lines) are shown in fig. 2 and are respectively located on the upstream side and the downstream side of the building structure, and the corresponding base side lines can be directly obtained by mouse pointing.
Step S104, based on the control point coordinates of each base surface side line, each base surface side line is correspondingly divided into a plurality of corresponding line segments.
And S106, creating a slope road line corresponding to each level of road and a slope control side line among each level of road based on the slope setting parameters and all line segments.
And S108, generating an original excavation surface based on all the slope horse road lines and all the slope control side lines, and generating a three-dimensional model of the excavation slope surface based on the original excavation surface and a preset terrain surface.
The embodiment of the invention provides a three-dimensional modeling method for excavating and releasing slopes of a hydraulic building, which is used for respectively obtaining the parameters of releasing slopes and the boundary lines of foundation surfaces of the hydraulic building; based on the control point coordinates of each base surface side line, correspondingly dividing each base surface side line into a plurality of corresponding line segments; based on the slope releasing parameters and all line segments, creating slope pavement lines corresponding to all levels of pavement and slope control side lines among all levels of pavement; and generating an original excavation surface based on all the slope pavement lines and all the slope control side lines, and generating a three-dimensional model of the excavation slope surface based on the original excavation surface and a preset terrain surface. By adopting the technology, the three-dimensional model of the slope surface can be quickly built by combining the existing topographic data only by acquiring the slope releasing parameters and the base surface side lines of the hydraulic building, so that the efficiency of slope surface releasing design is improved.
As one possible implementation, the starting point height Cheng Zhijun of each line segment is less than or equal to its ending point elevation value; based on this, the step S104 (i.e. dividing each of the base side lines into a corresponding plurality of line segments based on the control point coordinates of each of the base side lines) may include:
(11) Traversing all control points of each base surface boundary to extract parts, located between two adjacent control points, of each base surface boundary as an original line segment respectively, obtaining a plurality of original line segments corresponding to each base surface boundary, and distributing corresponding index numbers for each original line segment according to the traversing sequence of the control points of the corresponding base surface boundary.
Continuing the previous example, referring to fig. 3, for a certain selected base side line (i.e. the solid line with an arrow in fig. 3, the direction of the arrow is the direction of the base side line), the control points of the base side line can be traversed in sequence from the start point of the base side line to the end point of the base side line, when traversing to the current control point and the next control point adjacent to the current control point, the part of the base side line between the two control points is extracted as an original line segment, and so on, until all the control points of the base side line are traversed, the base side line can be split into 26 continuous original line segments (represented by line_1, line_2, … …, line_26 in fig. 3), and line segment lists LineList < line_1, line_2, … …, line_26> are formed; and then sequentially distributing corresponding index numbers for each original line segment according to the control point traversing sequence of the base surface side line.
(12) And acquiring the direction vector of each original line segment based on the control point coordinates of each base surface boundary.
Continuing with the previous example, referring to fig. 3, after splitting the building surface edge into 26 continuous original line segments, a corresponding direction vector can be calculated according to the start point coordinate and the end point coordinate of each original line segment, so as to obtain 26 direction vectors (which can be represented by vector_1, vector_2, … … and vector_26), and form a line segment list vector list < vector_1, vector_2, … … and vector_26>.
(13) And screening target original line segments with Z coordinate values of direction vectors smaller than 0 from the original line segments, exchanging the starting point and the end point of each target original line segment, and then adjusting the index sequence number of each target original line segment according to the control point elevation of the corresponding base surface side line to obtain a plurality of line segments corresponding to each base surface side line.
Continuing the previous example, referring to fig. 3, after the direction vector of each original line segment is obtained, since the Z coordinate value of the direction vector can reflect whether the corresponding original line segment points from high to low or from low to high, original line segments (in fig. 3, line_1, line_2, … …, line_15) with continuous index numbers and Z coordinate values of the direction vector smaller than 0 can be grouped as target original line segments pointing from high to low according to the index number positive sequence, and line sub-lists lin_1 < line 1, line_2, … …, line_15> are formed, original line segments (in fig. 3, line_16, line_17, … …, line_26) with continuous index numbers and Z coordinate values of the direction vector larger than 0 are grouped as another group according to the index number positive sequence, and line sub-lists lin_16, line_17, … …, line_26> are formed; referring to FIG. 4, linSubelist_1 is traversed to swap the start and end points of all target original line segments in LinSubelist_1, thereby ensuring that all line segments in LinSubelist_1 are pointed from low to high; referring to fig. 5, according to the index numbers of all the line segments in the control point height Cheng Diaozheng linsubelist_1 of the base surface edge, it is ensured that the starting point elevation or the end point elevation of the line segments in the linsubelist_1 is increased according to the positive sequence of the index numbers, and the sequence after the linsubelist_1 adjusts the line segment index numbers is linsubelist_1< line_15, line_14, … …, line_1>.
As a possible implementation manner, the step S106 (that is, creating the slope road line corresponding to each level of the road and the slope control edge line between each level of the road based on the slope setting parameter and the total line segments) may include:
(21) And creating a slope pavement line corresponding to each level pavement based on the slope releasing parameters and all line segments.
(22) And creating slope control side lines among the various levels of the horse roads based on the control point coordinates of the various slope horse road lines.
As a possible embodiment, the above (21) may include:
(211) All the line segments are traversed to extract the starting elevation value and the ending elevation value of each line segment.
Continuing with the previous example, as shown in FIG. 5, linSubelist_1< line_15, line_14, … …, line_1> and LinSubelist_2< line_16, line_17, … …, line_26> are traversed to extract the starting and ending elevation values of each line segment, respectively.
(212) And traversing the heights of the horse roads at each level in the slope releasing parameter in sequence from small to large according to the heights so as to sequentially determine target line segments of which the starting point height value and the end point height value are correspondingly matched with the heights of the horse roads at each level, and generating corresponding space line segments for the corresponding target line segments according to the slope gradient ratio between the horse roads at each level in the slope releasing parameter.
Continuing the previous example, after the heights of all levels of the horse ways to be put down and the slope ratios of the corresponding slopes among all levels of the horse ways are obtained, an elevation list of height list < height_1, height_2, height_3, … …, height_n > and a slope ratio list of slopeList < slope_1, slope_2, slope_3, … … and slope_n > can be established, wherein the heights in the elevation list are increased according to the positive sequence of index numbers, and the heights in the elevation list are in one-to-one correspondence with the slope ratios in the slope ratio list. Based on this, a traversal of the height list < height_1, height_2, height_3, … …, height_n > may be performed: each time an elevation value is traversed, it is determined whether a line segment exists in linsubelist_1< line_15, line_14, … …, line_1> and linsubelist_2< line_16, line_17, … …, line_26>, such that the elevation value is between the starting elevation value and the ending elevation value of the line segment, if so (i.e., a line segment exists such that the elevation value is between the starting elevation value and the ending elevation value of the line segment), the corresponding slope ratio is extracted from SlopeList < slope_1, slope_2, slope_3, … …, slope_n > according to the index sequence number of the elevation value, and the corresponding spatial line segment is generated for the line segment by the slope ratio.
For a certain line segment needing to generate a corresponding space line segment, the space line segment corresponding to the line segment can be generated according to the following principle: referring to FIG. 6, for a line segment AB in an XYZ coordinate system (Z coordinate value of each point in the coordinate system is the elevation value of the point), the elevation of the point A and the elevation of the point B are respectively the starting point elevation pS and the ending point elevation pE of the line segment AB, and the point B can be projected onto the horizontal plane where the point A is located to obtain point B'point, and according to the respective coordinates of the point A, the point B and the point B', calculating the length of the line segment AB|AB|, the length of the line segment BB|BB '|, and the length of the line segment AB|AB' |; when traversing to an elevation value height_i between the elevation of the point A and the elevation of the point B, finding a point C with the elevation of the height_i on the line AB, projecting the point C onto the horizontal plane of the point A to obtain a point C ', and calculating the length |CC ' |=height_i-pS of the line CC ' according to the respective coordinates of the point C and the point C; assuming that a D ' point exists on the horizontal plane where the A point exists so that the C ' D ' is vertical to the AD ', the D ' point can be projected on the horizontal plane where the C point exists so as to obtain the D point, the angle D ' AD is the inclination angle of a side slope, the slope ratio corresponding to the elevation value height_i is slope_i, and the length |DD ' |= |CC ' |=height_i-pS of the line segment DD ' can be obtained, because of the inclination angle of the side slope From this, the length |ad ' |= |dd ' |x slope_i of the line segment AD ' can be calculated; since ΔABB 'and ΔACC' are similar triangles to each other, the length +.>In ΔAD 'C', the angle is calculatedCalculating the score of C' point on line segment ABCalculating the coordinates of the C 'point according to the transformation and the respective coordinates of the A point and the B point (for example, calculating the coordinates of the C' point through an interface provided by design software and used for calculating the coordinates of the points on the line segment by the fraction); calculating the coordinates of a midpoint p_c of a line segment AC 'according to the respective coordinates of the point A and the point B, rotating the line segment AC' clockwise by 90 degrees by taking the p_c as a base point to obtain a line segment EF, determining the point E as a slope release point of the line segment AB on the left side and the right side of the line segment AB, determining the point F as a slope release point of the line segment AB on the right side of the line segment AB, and then calculating the respective coordinates of the point E and the point F according to the respective coordinates of the point A, the point B and the p_c; according to the respective points C', E and ACoordinates create vectors respectively->And->Calculating rotation axis vectorThe line segment AC 'rotates by taking the point C' as a base point, div as a rotating shaft and angle as a rotating angle to obtain a line segment C 'G, and the coordinate of the point G can be calculated according to the coordinate of the C' and div and angle; the point G is projected onto the horizontal plane where the point C is located to obtain a point H whose elevation is height_i, from which a space line segment CH can be generated.
After traversing each elevation value in the height list < height_1, height_2, height_3, … …, height_n > and generating a corresponding space line segment, a space line segment list slopetemist < temp line_1, temp line_2, temp line_3, … …, temp line_n > may be created based on all generated space line segments, and fig. 7 shows a space line segment generation result of a certain building surface edge line.
(213) And when the first target line segment of each building base surface side line is determined, generating a side slope road line based on the target line segment, a space line segment corresponding to the target line segment, the road width, the elevation of the road corresponding to the target line segment and the side slope ratio between roads corresponding to the target line segment.
For example, when determining a first target line segment of a boundary of a certain building base, determining an offset parameter of the target line segment based on an elevation of a level roadway corresponding to the target line segment and a slope ratio between the level roadways corresponding to the target line segment; wherein the offset parameter may include a horizontal offset distance and a vertical offset distance; and then, shifting the target line segment according to the shifting parameter of the target line segment to obtain a temporary slope-releasing multi-segment line, and generating a slope-releasing horse line based on the temporary slope-releasing multi-segment line, the horse road width and the space line segment corresponding to the target line segment.
(214) And when determining a target line segment except the first target line segment of each building base surface side line each time, generating a side slope road line based on the side slope road line generated last time, the space line segment corresponding to the target line segment, the road width, the elevation of the level road corresponding to the target line segment, the side slope ratio between the level roads corresponding to the target line segment and the elevation of the level road corresponding to the target line segment determined last time.
For example, when determining a target line segment other than the first target line segment of a certain base surface side line at each time, determining an offset parameter of the last generated side slope road line based on the elevation of the level road corresponding to the target line segment, the side slope ratio between the level road corresponding to the target line segment, and the elevation of the level road corresponding to the last determined target line segment; and then, shifting the last generated side slope road line according to the shift parameter of the last generated side slope road line to obtain a temporary slope-releasing multi-section line, and generating a side slope road line based on the temporary slope-releasing multi-section line, the road width and the space line segment corresponding to the target line segment.
Based on the step (211) to the step (214), each time a target line segment is obtained, the step of generating a slope catwalk line based on the temporary slope-releasing multi-segment line, the catwalk width, and the spatial line segment corresponding to the target line segment may include: acquiring an intersection point between the temporary slope-releasing multi-section line and a space line segment corresponding to the target line segment, and connecting the intersection point, a starting point of the space line segment and a control point of the temporary slope-releasing multi-section line positioned in front of the intersection point into a transition multi-section line; and taking the width of the road as an offset distance, and generating a slope road line by means of offsetting the transition multi-section line.
For ease of understanding, the operation of (213) above (214) is described herein by way of example in the context of linesublist_1 as follows:
first, referring to fig. 8, a first element in the lineublist_1 list is added as a first control edge of a side slope to the newly created ControlLineList1 list, and the element is denoted as ControlLineList1[0].
Second, referring to fig. 8, the method of traversing the height list < height_1, height_2, height_3, … …, height_n > according to the index sequence, when traversing to the height_1 between the starting point elevation pS and the end point elevation pE of the ControlLineList1[0], the height_1 takes the height_1 as the slope elevation, takes the ControlLineList1[0] as the slope base line, takes the slope_1 as the slope base line, performs slope by shifting the slope base line, the horizontal shift distance Δh_1= (height_1-pS) ×slope_i, the vertical shift distance Δv1= (height_i-pS), firstly, shifting the slope base line horizontally by Δh_1, then shifting the horizontally shifted line by Δv1, then, finding the first slope line after the vertical shift by the height_1, taking the slope_1 as the slope base line, and taking the slope base line as the intersection point between the first slope and the slope line as the slope base line, and the intersection point between the slope base line and the slope line in the slope list, and the slope line in the first slope list is added as the slope, and the intersection point between the slope line and the slope line is the slope 1, and the intersection point is the slope 1 is added to the control line in the first slope line.
Third, referring to fig. 8, the controlled linelist1[1] is horizontally shifted with the width of the road as a horizontal shift distance, and a portion of the horizontally shifted line between its end point and one of the control points adjacent to its end point is removed, after which all of the control points of the removed line and the start point of the first element in the slopetemp temlist are connected to one multi-segment line, which is added to the controlled linelist1 as a third control edge line of the side slope (i.e., one side slope road line), and the multi-segment line is denoted as a controlled linelist1[2].

Fig. 13 shows the result of the slope discharge of one base side line on the upstream side of the building structure (i.e. the upstream side excavated side line, i.e. the base side line corresponds to all the slope pavement lines generated).
As a possible embodiment, the above (22) may include: traversing the control points of each side slope road line in sequence to sequentially determine target control points of two adjacent side slope road lines, and connecting the target control points of the two adjacent side slope road lines determined each time into a side slope control side line to obtain side slope control side lines among the various levels of roads; wherein, the starting point and the end point of each side slope control side line are respectively the same in index number on the corresponding side slope pavement line.

Fig. 14 shows the upstream and downstream side excavation edge lines of the same hydraulic building and the slope control edge lines between the various levels of the catwalk.
For ease of understanding, the operation of step S108 (i.e., generating the original excavation surface based on all the slope road lines and all the slope control edges, and generating the three-dimensional model of the excavation slope based on the original excavation surface and the preset terrain surface) is described in detail herein by taking a specific application as an example as follows:
step 1, the original excavated Mesh surface (i.e., the original excavated surface) shown in fig. 15 is generated by designing a software self-contained tool (e.g., a "creating triangle net through contour" tool) using the upstream and downstream side excavation edge lines shown in fig. 14.
And 2, extracting an intersection line (namely an excavation opening line) between two Mesh surfaces by using the three-dimensional terrain Mesh surfaces (namely a preset terrain surface) and the original excavation Mesh surfaces generated in the step 1 through an interface provided by design software (such as an interface for calculating the intersection line between the two Mesh surfaces). Fig. 16 shows a case where a three-dimensional topographic Mesh surface intersects with an originally excavated Mesh surface, and fig. 17 shows an excavated opening line.
The step 2 can be realized by a secondary development related program mode, the input of the program is a three-dimensional terrain Mesh surface and the original excavation Mesh surface generated in the step 1, and the output of the program is the intersection line of the two Mesh surfaces.
And 3, cutting the original excavation surface by using the excavation opening line extracted in the step 2 as a boundary through a tool (such as a Fence cutting tool) provided with design software, and finally reserving a Mesh surface within the excavation opening line range to generate an accurate excavation surface (shown in fig. 18), wherein the accurate excavation surface is a three-dimensional model of the excavation slope.
In the three-dimensional modeling method for the hydraulic building to excavate and release the slope, the control side line of the excavation and release the slope can be directly generated based on the parameters of the slope release design (namely the slope release parameters) and the side line of the foundation surface to be subjected to slope release, the original excavation Mesh surface is directly generated according to the control side line of the excavation and release the slope, the excavation opening line is obtained by extracting the intersection line between the original excavation Mesh surface and the three-dimensional terrain Mesh surface, and then the original excavation Mesh surface is cut by taking the excavation opening line as a boundary, so that the three-dimensional model of the excavation and release slope is finally obtained.
