Example 1
Referring to fig. 1 and fig. 2, the method for converting a two-dimensional pipeline into a three-dimensional model provided in this embodiment specifically includes the following steps:
step S101: and generating a three-dimensional straight pipe according to the vector information of the center line segment of the pipe gallery in the two-dimensional pipeline.
Step S102: and calculating the height difference between the adjacent three-dimensional straight pipes, and generating a three-dimensional standpipe according to the height difference.
Step S103: and calculating a yaw angle between the adjacent three-dimensional straight pipes, and generating a three-dimensional elbow according to the yaw angle.
Step S104: and combining the three-dimensional straight pipe 1, the three-dimensional vertical pipe 3 and the three-dimensional elbow 2 into a three-dimensional pipe gallery model.
As will be explained in detail below, the step S101 is to generate a three-dimensional straight pipe according to vector information of a centerline segment of a pipe gallery in a two-dimensional pipeline, and specifically includes:
(1) because the two-dimensional pipeline is formed by connecting a plurality of sections of pipeline center line segments, the vector information of the pipeline center line segments in the two-dimensional pipeline, namely the starting point coordinate (S) is obtainedx,Sy) Endpoint coordinate (E)x,Ey) Starting point frame top elevation ShTop elevation of terminal frame EhAnd a pipe diameter DN.
(2) Calculating pitch angle of central line segment of pipe gallery
So as to consider the vertical swing of the central line segment of the pipe gallery.
(3) Calculating the yaw angle of the center line segment of the pipe gallery
So as to consider the horizontal swing of the central line segment of the pipe gallery.
(4) Calculating the straight tube length of the center line segment of the pipe gallery
I.e. the absolute length of the pipe gallery centre line segment in the horizontal direction is calculated from the above coordinates.
(5) Calculating straight pipe pipeline height of central line segment of pipe gallery
I.e. the absolute length of the pipe gallery centre line segment in the vertical direction is calculated from the above coordinates.
(6) And matching a preset three-dimensional model according to the pipeline height H, the pipe diameter DN and the straight pipe length L of the straight pipe and generating the three-dimensional straight pipe. It should be noted that the preset three-dimensional model can be flexibly selected according to the user's usage requirement, for example, a standard model generated directly in the CAD in advance according to the two-dimensional pipeline data, and the like. In the implementation process, the calculated height H of the straight pipe pipeline, the calculated pipe diameter DN and the calculated length L of the straight pipe are put into a three-dimensional model matched with the straight pipe pipeline, and the three-dimensional straight pipe is generated. In addition, in the matching selection process, the input and output parameters, the number of parameters, and the like of the pre-generated standard model are uncertain, and when the matched three-dimensional model is selected, the three-dimensional model matched with the parameters and the number of parameters needs to be searched.
Step S102, calculating the height difference between adjacent three-dimensional straight pipes, and generating a three-dimensional vertical pipe according to the height difference, specifically comprising:
(1) because the three-dimensional vertical pipe is arranged between the three-dimensional straight pipes for supporting, at least two pipe gallery central line segments which are horizontally arranged are needed for calculating and generating the three-dimensional vertical pipe, the former pipe gallery central line segment is marked as F in the implementation process, and the latter pipe gallery central line segment connected with the former pipe gallery central line segment is marked as B.
(2) Terminal frame top height F for obtaining central line segment of previous pipe galleryEhBy the vector parameter end point frame ceiling height FEhThe height of the center line segment of the previous pipe gallery is measured.
(3) Acquiring the starting point frame jacking height B of the center line segment of the next pipe galleryShStarting the gantry height B by the vector parameterShThe height of the central line segment of the latter pipe gallery is measured. And the center line segment of the previous pipe gallery and the center line segment of the next pipe gallery are adjacently connected.
(4) Then, according to the terminal frame ceiling height FEhAnd starting point frame top height BShCalculating the height difference V between three-dimensional straight pipesh＝|BSh-FEhAnd l, because the two height values are uncertain, the height difference between the three-dimensional straight pipes is measured through calculation of absolute values.
(5) According to the height difference VhAnd the pipe diameter DN is matched with a preset three-dimensional model and a three-dimensional standpipe is generated. Similarly, it should be noted that the preset three-dimensional model can be flexibly selected according to the user's use requirement, for example, a standard model generated in advance in CAD directly according to the two-dimensional pipeline data. In practice, the calculated height difference VhAnd putting the pipe diameter DN into a three-dimensional model matched with the pipe diameter DN and generating a three-dimensional standpipe. In addition, in the matching selection process, the input and output parameters, the number of parameters, and the like of the pre-generated standard model are uncertain, and when the matched three-dimensional model is selected, the three-dimensional model matched with the parameters and the number of parameters needs to be searched.
The step S103 is to calculate a yaw angle between adjacent three-dimensional straight pipes, and generate a three-dimensional elbow according to the yaw angle, and specifically includes:
(1) obtaining the yaw angle of the central line segment F of the previous pipe gallery
Before consideringThe left and right swinging of a central line segment of a pipe gallery in the horizontal direction.
(2) Obtaining the yaw angle of the central line segment F of the next pipe gallery
To take into account the horizontal sway of the latter pipe gallery centre line segment. When the left-right swinging condition of the central line segment of the previous pipe gallery in the horizontal direction is consistent with the left-right swinging condition of the central line segment of the next pipe gallery in the horizontal direction, the three-dimensional straight pipe and the three-dimensional vertical pipe can be directly connected; under most circumstances, when the horizontal swing condition of the center line segment of the current pipe gallery is inconsistent with the horizontal swing condition of the center line segment of the next pipe gallery, corresponding difference values can be generated between the three-dimensional straight pipe and the three-dimensional vertical pipe, and elbows with different curvatures are needed to be connected.
(4) Thus, the angle of rotation of the elbow is calculated from the yaw angle between the two pipe gallery centre line segments
(5) In addition, in order to consider the left-right swing of the elbow in the horizontal direction, the yaw angle of the elbow is calculated during implementation
(6) Then according to the rotation angle WΦAnd yaw angle
And generating the three-dimensional elbow. It should be noted that, the caliber width of the three-dimensional elbow is slightly larger than the pipe diameter DN, and the numerical value of the caliber width of the three-dimensional elbow can be flexibly set according to the situation in specific implementation.
Step S104 above combines three-dimensional straight pipe, three-dimensional standpipe and three-dimensional elbow into three-dimensional pipe gallery model, specifically including:
(1) in the process of forming the three-dimensional pipe gallery model, coordinates of a starting point of the model are determined, and the starting point of the model is usually determinedThe point coordinates coincide with the start point of the three-dimensional straight pipe in the selected spatial range, and therefore, in implementation, are based on the start point coordinates (S)x,Sy) And a straight pipe line height H to generate a starting point (S) of a three-dimensional straight pipex,Sy,H)。
(2) Then, according to the pitch angle theta and the yaw angle of the three-dimensional straight pipe in the step (1)
The spatial direction of the three-dimensional straight pipe is determined, for example, the first quadrant direction with the starting point as the origin, and the like.
(3) To determine a good origin, i.e. the starting point of a three-dimensional straight tube (S)x,SyAnd H) is superposed with one end of a three-dimensional straight pipe, and one end point of the three-dimensional straight pipe is the starting point.
(4) After the origin point is determined, a three-dimensional straight pipe needs to be placed in the area where the space direction is located, and the pitch angle theta and the yaw angle theta are calculated
And placing the three-dimensional straight pipes in a space coordinate system for the space direction, and correspondingly, sequentially arranging a plurality of generated three-dimensional straight pipes backwards.
(5) And then, placing a three-dimensional vertical pipe between the connected three-dimensional straight pipes in a space coordinate system, wherein the three-dimensional vertical pipe placing principle needs to be determined according to the positions of the central line segment of the previous pipe gallery and the central line segment of the next pipe gallery. And vector information of the central line segment of the previous pipe gallery is used for generating the previous three-dimensional straight pipe.
(6) And then, connecting the three-dimensional straight pipe and the three-dimensional vertical pipe into a closed model by using the generated three-dimensional elbow. When the specific situation of the underground space needs to be examined, the specific situation can be judged through the closed model. When the models of other pipelines directly enter the closed model, the space conflict is shown, and when the models of other pipelines effectively bypass the closed model, the space condition is shown to be good, and the closed model can be implemented on the space.
In addition, for facilitating the viewing in space, the method for converting the two-dimensional pipeline into the three-dimensional model further comprises the following steps: when the closed model is turned, the three-dimensional straight pipe, the three-dimensional vertical pipe and the three-dimensional elbow can rotate by 720 degrees. Through the rotation, the space condition of the closed model can be effectively and accurately checked.
In addition, in order to make people aware of the existence of the space conflict, the method for converting the two-dimensional pipeline into the three-dimensional model further comprises the following steps: when a space conflict is found in the process of carrying out space detection on the closed model, an alarm signal is sent out, for example, a sound or light is sent out.
In summary, the method for converting a two-dimensional pipeline into a three-dimensional model provided by the embodiment includes: firstly, according to the vector information of the central line segment of the pipe gallery in the two-dimensional pipeline, a three-dimensional straight pipe is generated, then, the height difference between the adjacent three-dimensional straight pipes is calculated, a three-dimensional vertical pipe is generated according to the height difference, secondly, the yaw angle between the adjacent three-dimensional straight pipes is calculated, a three-dimensional elbow is generated according to the yaw angle, then, the three-dimensional straight pipe, the three-dimensional vertical pipe and the three-dimensional elbow are combined into a three-dimensional pipe gallery model, through the processing process, the three-dimensional model can be converted into the three-dimensional model according to the two-dimensional pipeline, and therefore, people can conveniently look up the space condition of the pipeline, the process that people look up and survey in large quantities is omitted, the accurate assessment of the space condition of the position of the pipeline can be achieved, and the method is convenient and fast.
