In this embodiment, a plane equation and a linear parameter equation may be established according to the two-dimensional view of the cable working well profile and the coordinate information of each component and the profile in the two-dimensional view of the cable well body component, and the stretching profile point may be obtained according to the plane equation and the linear parameter equation. Specifically, the plane equation and the linear parameter equation may be:
plane equation: a (x-x 0) +B (y-y 0) +C (z-z 0) =0 (1)
Linear parameter equation: x=x1+mt; y=y1+nt; z=z1+pt (2)
The method comprises the steps of obtaining a straight line parameter equation t, obtaining each node of a specified stretching contour, performing stretching calculation, wherein x0, y0 and z0 represent one point on a plane, A, B and C represent plane normal vectors, x1, y1 and z1 represent one point on a straight line, m, n and p represent straight line normal vectors, and t represents parameters.

As described in the above embodiment, after the cable working well profile solid model and the cable well body part solid model are obtained, in order to verify whether the constructed solid model is standard and valid, the solid model needs to be checked for validity, specifically, the entity validity check may be performed according to the euler formula.

The euler formula, also known as the euler theorem, also known as the You La formula, is a formula used in the field of complex analysis that relates trigonometric functions to complex exponential functions. Specifically, the euler theorem is defined in that on any regular spherical map, R denotes the number of regions, V denotes the number of vertices, and E denotes the number of boundaries, and r+v-e=2. In computer graphics, the euler formula is often used to check entity validity. In this embodiment, when a polyhedron without through-polyhedron holes is inspected, the euler formula V-e+f=2 is used, where V is the number of top points, E is the number of sides, and F is the number of faces; when inspecting a polyhedron with holes through the polyhedron, the generalized euler formula V-e+f-h=2 (C-G) is used, where V is the number of vertices, E is the number of edges), F is the number of faces, H is the number of holes on the surface of the body, G is the number of holes through the polyhedron, and C is the number of independent unconnected polyhedrons. When a part is detected to be out of the definition of the Euler formula, the part is proved to be invalid, and at the moment, the parameter reconstruction design of the part needs to be adjusted to perform corresponding calculation and clipping. In the embodiment, the Euler formula is adopted to perform entity validity check, so that the standardization and validity of the three-dimensional model of the cable working well can be ensured.
In one embodiment, performing validity checking on the wireline work well profile solid model and the wireline well body component solid model according to a per-entity validity checking algorithm comprises: step S640, checking whether the cable working well outline solid model and the cable well body part solid model meet the sealing requirement according to the entity regular set operation.
The regular set operation is mainly used for checking whether an entity has a closed state, and the fact that an effective entity has a closed state means that the effective entity is still an effective entity after a series of set operations, and general set operations cannot meet the requirement. Specifically, the regular set operation includes regular union, regular intersection and regular difference operation, and the result of the set operation can be ensured to be a regular body through the regular set operation. In this embodiment, the regular set operation is adopted to avoid the phenomena of edge suspension, surface suspension, edge deficiency, surface deficiency and the like on the surface of the body.
And step S800, assembling the effective cable well body part solid model and the cable working well outline solid model to obtain cable working well three-dimensional model data.
After checking the validity of the entity, the cable well body part entity model and the cable working well outline entity model can be assembled according to the space position information and the relative space position of each cable well body part entity model and the cable working well outline entity model to obtain three-dimensional model data of the cable working well. Specifically, the method comprises the steps of assembling a reserved hole entity model, a manhole entity model, a water collecting ditch entity model and a well profile entity model, assembling a stand column entity model and a bracket entity model, and then assembling the stand column entity model and the bracket entity model into the well profile entity model to obtain three-dimensional model data of the cable working well.

The whole process is based on the two-dimensional view of the cable working well, and the two-dimensional view of the cable working well is reversely converted into a three-dimensional entity model by adopting a stretching algorithm, so that important entity basis and reference are provided for construction, the construction accuracy is improved, the construction time is shortened, and the construction efficiency is improved.
In one embodiment, the method includes assembling the effective cable well body part solid model and the cable working well outline solid model to obtain the cable working well three-dimensional model data, and then further includes: step S850, using a scan representation, represents the three-dimensional model data of the cable work well.
The basic principle of the scan representation is to scan a point, an edge or a surface in space along a certain path, and to represent a three-dimensional object by using the obtained scan trajectory. Scan representation requires defining the trajectory of the scanned object and the scanned motion. The scanning method mainly comprises the following steps: translation scanning, rotation scanning and generalized scanning. In this embodiment, the three-dimensional model data of the cable working well may be represented by a rotational scanning method.
In one embodiment, the method includes assembling the effective cable well body part solid model and the cable working well outline solid model to obtain the cable working well three-dimensional model data, and then further includes: and step S900, converting the three-dimensional model data of the cable working well into a two-dimensional view of the cable working well by adopting a projection algorithm.
In practical application, in order to facilitate the observation of parameters and details of the components from different visual angles, the three-dimensional model of the cable working well can be converted into a two-dimensional view of the cable working well after the three-dimensional model of the cable working well is generated, so that the three-dimensional view is switched to the two-dimensional view, and the three-dimensional view is convenient to view. Specifically, a projection algorithm is adopted to convert the three-dimensional model data of the cable working well into a two-dimensional view of the cable working well. The projection algorithm is to project the shadow of the graph onto a plane ohm line, in this embodiment, the adopted projection algorithm is an oblique projection algorithm, and specifically, the adopted write projection algorithm may be:
tan(α)＝(zk-z)/L；
L1＝ctgα；
xp＝x+L1*(zk-z)*cos(β)；
yp＝y+L1*(zk-z)*sin(β)
Wherein, alpha represents the included angle between the oblique parallel projection line and the connecting line on the projection plane, beta represents the included angle between the projection line of the observation plane and the horizontal direction of the projection plane, L represents the projection line length of the observation plane, zk represents the orthographic projection point Z, x to the projection plane, Z represents the three-dimensional coordinates, xp, yp and zK represent the projection coordinates. The three-dimensional view is converted into the two-dimensional view through the oblique projection algorithm, so that the conversion between the three-dimensional view and the two-dimensional view is realized, the views can be conveniently switched, and the observation of parameters and details of the cable working well component from multiple view angles is realized.
