Detailed Description
The following description of the embodiments of the present invention will be made apparent and fully in view of the accompanying drawings, in which some, but not all embodiments of the invention are shown. 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.
In addition, the technical features of the different embodiments of the present invention described below may be combined with each other as long as they do not collide with each other.
First, technical terms used in the embodiments of the present invention will be described.
The primitives: the graphic primitive is an operable minimum display unit in graphic informatization engineering. Such as: a column, in the patterning software, is shown as a cuboid, which is described as a primitive; the length, width, height, steel bar information and other attributes of the graphic element can be adjusted.
A component: when the core characteristics of most of the primitives are the same, merging the primitives into a component and completing definition of the common characteristic data in the component in order to avoid repeated definition; such as: one set of 400 x 3000 square columns is the same member, and the other set of 500 radius, 3000 height columns is the other member.
Type of component: when a group of components belong to the same class from the service, the components are marked as one class, and the description is given by the component types. For example: columns, beams, walls, panels, are just different component types.
The same layer: the same layer, referred to herein, represents that the same type of primitive for CAD is below one layer. For example: all well primitives within the CAD drawing are under one layer.
In the existing construction engineering software, many support users to construct a three-dimensional model according to drawings after CAD drawings are imported, and most of the realization modes are that users manually draw the three-dimensional model according to the pipelines of the drawings according to the drawings, but the three-dimensional model takes a lot of time for users, and in order to save the operation time of the users, some software provides a scheme capable of quickly generating pipe member primitives such as drain pipes, and when the pipe member primitives are generated, the corresponding relations between the pipe length and the pipe diameter of each pipeline marking information in the CAD drawings and the pipelines need to be identified.
In the prior art, users are often required to manually identify the pipeline corresponding to each pipeline label. However, because the drawing scene is complex, the pipeline marking information may be under the same layer or not, the connection direction of the pipeline marking information and the pipeline may not correspond, and one pipeline marking may correspond to a plurality of pipelines and the like, so that the conventional manual pipeline marking identification mode is long in time consumption, low in identification efficiency and easy to identify errors.
Based on the above problems, an embodiment of the present invention provides a method for identifying a pipeline label, as shown in fig. 1, where the method specifically includes the following steps:
Step S101: and obtaining the pipe length label in the area to be identified of the target building engineering drawing.
In the embodiment of the present invention, the target building engineering drawing is taken as a CAD drawing for example, and in practical application, the target building engineering drawing may also be a building drawing with other formats. The region to be identified is a region corresponding to a user expected to generate a pipe member primitive on the CAD drawing. The pipe length is marked as a marking frame with a pipe length value on the CAD drawing, and only the pipe length value may be marked in the pipe length marking, and the pipe diameter value and the pipe length value are sometimes marked in one marking frame.
Step S102: and respectively calculating the distance from each pipe length mark to each pipeline in the area to be identified.
Specifically, step S102 is performed by obtaining a center point marked by each tube length; the distance from each tube length label to each pipeline is determined based on the distance from the center point of each tube length label to each pipeline. The distance between each tube length label and the different tube lines is thus determined from the point-to-line distance.
Step S103: and determining a first pipeline corresponding to each pipe length mark based on the distance from each pipe length mark to each pipeline in the area to be identified.
In the CAD drawing design, a tube length label is usually set near a corresponding tube, and one tube length label may be the total length of a plurality of tubes connected in sequence, and the closer the tube length label is to the tube, the greater the likelihood that the tube belongs to the label range of the tube length label, so that one tube belonging to the tube length label can be determined according to the distance between the tube length label and the tube.
Step S104: and extracting a pipeline set meeting the pipe length marking information along the connection direction of the first pipeline based on the pipe length marking information of the first pipe length marking corresponding to the first pipeline.
The pipeline set at least comprises a first pipeline or comprises the first pipeline and other pipelines which are connected with the first pipeline in sequence and belong to the first pipeline length label.
Step S105: the first pipe length label is matched to the set of pipes.
Specifically, by acquiring the numbers of all the pipelines in the pipeline set, a corresponding relation between the pipeline numbers and the first pipeline length mark is established, so that the automatic identification of the pipeline corresponding to the pipeline length mark is realized.
By executing the steps, the pipeline marking identification method provided by the embodiment of the invention determines the pipeline belonging to the pipeline marking by utilizing the distance between the pipeline marking and the pipeline, and then extracts the pipeline set for matching according to the pipeline length value of the pipeline marking along the connection direction of the pipeline, thereby realizing the automatic identification of the pipeline corresponding to the pipeline length marking, improving the identification efficiency of the pipeline marking, avoiding the problem that the manual identification is easy to cause false identification, improving the accuracy of the identification result of the pipeline marking, and further improving the user experience.
Specifically, in one embodiment, the step S103 specifically includes the following steps:
Step S301: and obtaining the distance from each pipe length mark to the current pipeline and the pipe length value of each pipe length mark.
The length values are recorded in one length label, l=24.35m and l=18.40m shown in fig. 2 are respectively a length label and a length label B, which are simply referred to as a length a and a length B, a line segment in the middle of the length a and the length B is a target line, and the length values corresponding to the length a and the length B are respectively 24.35m and 18.40m.
Step S302: and respectively inputting the distance from each pipe length mark to the current pipeline and the pipe length value of each pipe length mark into a pipeline identification model to obtain a prediction score corresponding to each pipe length mark.
Specifically, as shown in fig. 2, assuming that the shortest distance from the center point ptA of the pipe length a to the target line is MinA, the pipe length value is ALength; the shortest distance from the center point ptB of the pipe length B to the target line is MinB, and the pipe length value is BLength; the actual length of the target line is ActualLength; weight setting: pipeline distance weight wDis, pipeline length weight lDis, where the sum of wDis and lDis is equal to 1. The specific weight setting can be flexibly adjusted according to the design habit of the CAD drawing, and the invention is not limited to the design habit.
Wherein the pipeline recognition model is represented by the following formula:
M＝MinN*wDis+(NLength-ActualLength)*lDis
Wherein M is a prediction score of the pipeline identification model, minN is the shortest distance from the Nth pipe length to the target pipeline, and NLength is the pipe length value of the Nth pipe length.
Predicted score for tube length a = MinA x wDis + (ALength-ActualLength) x lDis;
Predicted score for tube length B = MinB x wDis + (BLength-ActualLength) x lDis.
Step S303: and determining the pipe length label with the highest prediction score as the current pipe length label corresponding to the current pipeline.
Illustratively, assuming that the predictive score for tube length B in fig. 2 is greater than the predictive score for tube length a, tube length B is determined to be the tube length label corresponding to the target pipeline. Therefore, the pipeline distance weight wDis and the pipeline length weight lDis can be flexibly adjusted through the drawing habit of the CAD drawing, and the accuracy of the pipeline length labeling identification result is ensured. The embodiment of the invention can adapt to different CAD drawing habits, has wide application range and strong flexibility, and further improves the use experience of users.
Specifically, in an embodiment, the step S104 specifically includes the following steps:
Step S401: starting from the first pipeline, the connecting pipelines are sequentially extracted along the connecting direction of the first pipeline to form a pipeline set.
Illustratively, as shown in fig. 3, the numbers above the pipelines are the pipeline numbers corresponding to the pipelines, the numbers below the pipelines are the actual lengths of the pipelines corresponding to the pipelines, and assuming that the pipeline No. 3 is matched with the length label of the pipeline No. 6, the process is carried out from one direction of the pipeline No. 3 connection until the collection formed by all the pipelines with the small remainder equal to 6 is found.
Step S402: and determining the actual length of each pipeline set based on the total length of each pipeline set in the target building engineering drawing and the scale corresponding to the target building engineering drawing.
Specifically, on the CAD drawing, the actual length can be obtained by the dimension on the CAD drawing according to a fixed scale, and, for example, assuming that the scale is 1:5000, 1cm on the CAD drawing represents the actual 50m, and if the total length of all the lines in the line set on the CAD drawing is 10cm, the actual length of the line set is 500m, etc., the present invention is not limited to this.
Step S403: based on the actual length of each pipeline set, pipeline sets with the actual length equal to the pipe length value marked by the first pipe length are screened.
Illustratively, as shown in FIG. 3, from pipeline number 3, for example, find first left, find number 3, 2, overall length 5, then find in one direction of the other connection, find number 3, 4, 5, overall length 6. And judging that the right side is more in line with the actual value, so that the pipeline sets of No. 3, no. 4 and No. 5 are selected as the pipeline sets corresponding to the pipe length label L6.
Therefore, the actual length of the pipeline set is calculated by utilizing the scale and the total length of the pipeline set on the CAD drawing, and the matching relation between the pipe length mark and the pipeline set can be accurately matched by comparing the pipe length value of the pipe length mark with the actual length, so that the accuracy of the final pipe length mark identification result is further improved, and the user experience is improved.
Specifically, in an embodiment, before the step S104, the method for identifying a pipeline label specifically further includes the following steps:
Step S41: and acquiring a first length of the first pipeline in the target building engineering drawing and a scale corresponding to the target building engineering drawing.
The first length is the actual length of the first pipeline on the CAD drawing, such as 3 cm.
Step S42: a first actual length of the first pipeline is determined based on the first length and the scale.
Specifically, the actual length calculation manner of the first pipeline is similar to the total length calculation manner of the pipeline set, and will not be described herein.
Step S43: judging whether the first actual length is smaller than a tube length value marked by the first tube length; executing step S104 when the first actual length is smaller than the first pipe length marked pipe length value; and when the actual length is equal to the pipe length value of the first pipe length mark, matching the first pipe length mark with the first pipeline.
In practical application, a condition that one pipe length label corresponds to one pipe line may exist, so that the identification of the pipe length label of the independent pipe line can be directly realized by comparing whether the actual length of the independent pipe line is matched with the pipe length value of the pipe length label, and the subsequent steps are not required to be executed, so that the identification efficiency of the pipe length label is further improved.
Specifically, in an embodiment, the method for identifying a pipeline label specifically further includes the following steps:
Step S106: judging whether the first pipe length label contains pipe diameter label information or not; when the first pipe length label does not include pipe diameter label information, step S107 is performed. And when the pipe diameter marking information is not contained in the first pipe length marking, matching the pipe diameter marking information contained in the first pipe length marking with the pipeline set. . In practical application, the pipeline label comprises a pipe length label and a pipe diameter label, and through realizing automatic matching of the pipe diameter label and the pipeline, automatic matching of the complete pipeline label and the pipeline is realized, the efficiency of identifying the pipeline label is further improved, and the use experience of a user is improved.
Step S107: and obtaining all pipe diameter labels in the area to be identified of the target building engineering drawing.
In practical application, in some CAD drawings, the pipe length label and the pipe diameter label are in different label frames, so that the identification of the pipe diameter label is required to be completely realized, and the matching of the pipe diameter label and the pipe diameter is also required to be realized. And the independent pipe diameters are marked as a marking frame with pipe diameter values on the CAD drawing.
Step S108: and respectively calculating the distance from each pipe diameter mark to each pipeline in the area to be identified.
Specifically, the step S108 is performed by obtaining the center point of each pipe diameter mark; and determining the distance from each pipe diameter mark to each pipeline based on the distance from the central point of each pipe diameter mark to each pipeline. Thereby determining the distance between each pipe diameter label and different pipelines according to the distance from the point to the line.
Step S109: and determining a second pipeline corresponding to each pipe diameter mark based on the distance from each pipe diameter mark to each pipeline in the area to be identified.
In CAD drawing design, the pipe diameter label is usually arranged near the corresponding pipe, and the closer the pipe diameter label is to the pipe diameter, the greater the possibility that the pipe belongs to the label pipe diameter value of the pipe diameter label is, so that one pipe belonging to the pipe diameter label can be determined according to the distance between the pipe diameter label and the pipe.
Step S110: and acquiring a first pipe diameter label corresponding to any pipe in the pipe set based on the second pipe corresponding to each pipe diameter label.
Specifically, any one of the pipelines may have a pipe diameter label corresponding to the pipeline set, and since each pipeline in the pipeline set belongs to a pipe length label, and a plurality of pipelines which are sequentially connected and have the same pipe diameter in the CAD drawing are labeled with the same pipe length, the pipe diameter value of each pipeline in the whole pipeline set can be obtained through the pipe diameter label of any one of the pipelines in the pipeline set. Therefore, the identification efficiency of pipe diameter labeling is further improved, and the use experience of a user is improved.
Step S111: and matching the first pipe diameter label with the pipeline set.
Specifically, a matching relationship can be established between the pipe diameter value corresponding to the first pipe diameter mark and the serial number of each pipe in the pipe assembly, so that automatic identification of the pipe diameter mark is realized, the pipe identification efficiency is further improved, and the user experience is improved.
In addition, in practical application, a pipeline mark which is parallel to the pipeline and closest to the pipeline can be found through the current pipeline, whether the pipeline mark comprises a pipe diameter value and a pipe length value or not is judged, the pipe length value is consistent with the actual length of the current pipeline in the CAD drawing, and if the pipeline mark comprises the pipe diameter value and the pipe length value, and the pipe length value is consistent with the actual length of the current pipeline in the CAD drawing, the pipeline mark is directly matched with the current pipeline.
Illustratively, as shown in FIG. 4, it is assumed that the total pipe lengths of the 1,2, 3 pipes are 41m, the pipe diameters are 300mm, the total pipe lengths of the 4, 5 pipes are 35m, and the pipe diameters are 500mm. By adopting the modes from the step S301 to the step S303, the pipeline 2 can be matched with the pipe diameter DN300, the pipeline 3 is matched with the pipe length L41m, the pipeline 4 is matched with the pipe diameter DN500, and the pipeline 5 is matched with the pipe length L35m. And then finding all pipelines matched with the lengths of the pipelines, namely 3 and 4, finding the marked pipe length of the pipeline 3 to be 41m, finding the pipe length sum of other pipelines connected with the pipeline 3 (the pipelines marked with the pipe lengths) and the latest 41m pipe collection, namely finding the pipe lengths of the pipelines 1,2 and 3 to be closest to 41m, finding the pipeline marked with the pipe diameters from the found pipelines, and assigning the pipe diameters DN300 to the pipelines 1 and 3 without the pipe diameters if the pipeline 2 is matched with the pipe diameters.
In practical application, the pipeline can be matched with the independent pipe length, the independent pipe diameter and the pipe length plus pipe diameter, after the matching, the independent pipe diameter and the independent pipe length matched with the same pipeline are combined, then all pipeline marks matched with the pipeline can be obtained, an optimal pipeline path is searched through the values of the pipe length marks, the mark of the pipe length is considered to be given to the pipes, then the pipe mark matched with the pipe diameter is found on the pipes, and then the pipe diameter is given to the pipes without the pipe diameter, so that the pipe diameter of the pipeline is found. If the pipe with the pipe diameter mark is not found, adopting default pipe diameter and the like, and the invention is not limited to the default pipe diameter.
In addition, in practical application, since only the pipeline label corresponding to the main pipeline is required to be identified, and the branch pipeline does not need to be identified, the embodiment of the invention also provides a method for judging whether the pipeline is the main pipeline or the branch pipeline, which comprises the following specific processes:
Illustratively, as shown in FIG. 5, there are 4 lines, the main lines are 1,2, 3, and the branch lines are 1, 4. The method for judging whether the current pipeline is a branch pipeline comprises the steps of obtaining the starting point and the end point of the current pipeline, constructing a three-dimensional bounding box through a starting point position and then adding a fault tolerance, extracting all primitives intersected with the bounding box, judging the position relation between the point on the current pipeline and the primitives, and if other pipelines except the current pipeline can be found, indicating that the starting point of the current pipeline is connected with other pipelines.
