The component types are as follows: when a group of components belong to the same category from the business, the components are marked as a category and are described by component types. For example: columns, beams, walls, panels, are different types of components.
And (3) same layer: the same layer is referred to herein as representing the same type of CAD primitives under one layer. For example: all well primitives in the CAD drawing are under one layer.
In the existing building engineering software, a lot of users are supported to construct a three-dimensional model according to drawings after the users import CAD drawings, and most of the implementations are that the users manually draw the three-dimensional model according to the drawings by pipelines of the drawings, but this takes a lot of time for the users.
In the prior art, a user is usually required to manually identify the pipeline corresponding to each pipeline label. However, due to complex drawing scenes, pipeline label information may or may not be on the same layer, the connection direction of the pipeline label information and the pipeline may not correspond, and one pipeline label may correspond to multiple pipelines, etc., which makes the conventional manual pipeline label identification method time consuming longer, and has low identification efficiency and is prone to identification errors.
Based on the above problem, an embodiment of the present invention provides a pipeline label identification method, as shown in fig. 1, the pipeline label identification method specifically includes the following steps:
step S101: and acquiring the pipe length mark in the area to be identified of the target architectural engineering drawing.
In the embodiment of the present invention, a target architectural engineering drawing is taken as an example for description, in practical applications, the target architectural engineering drawing may also be a building drawing in other formats, and the present invention is not limited thereto. The area to be identified is an area corresponding to a pipe component graphic element expected to be generated by a user on a CAD drawing. The tube length is marked on the CAD drawing as a marking box with a tube length value, the tube length marking may only be the tube length value, and sometimes the tube diameter value and the tube length value are marked in one marking box, which is not limited in the present invention.
Step S102: and respectively calculating the distance between each pipe length label and each pipeline in the area to be identified.
Specifically, the step S102 is performed by obtaining a central point of each tube length label; and determining the distance between each pipe length label and each pipeline based on the distance between the central point of each pipe length label and each pipeline. The distance between each tube length label and a different tube line is thus determined from the point-to-line distance.
Step S103: and determining a first pipeline corresponding to each pipe length label based on the distance from each pipe length label to each pipeline in the area to be identified.
The method comprises the following steps of designing a CAD drawing, wherein pipe length labels are usually arranged near corresponding pipelines in the CAD drawing, one pipe length label can be the total length of a plurality of pipelines connected in sequence, and the closer the pipe length label is to the pipelines, the higher the possibility that the pipeline belongs to the label range of the pipe length label is, so that the pipeline belonging to the pipe length label can be determined according to the distance between the pipe length label and the pipelines.
Step S104: and extracting a pipeline set meeting the length marking information along the connection direction of the first pipeline based on the length marking information of the first pipeline corresponding to the length marking.
The pipeline set at least comprises a first pipeline or comprises the first pipeline and other pipelines which are sequentially connected with the first pipeline and belong to the first pipe length label.
Step S105: the first pipe length label is matched with the set of pipes.
Specifically, the corresponding relation between the pipeline number and the first pipe length label is established by acquiring the number of each pipeline in the pipeline set, so that the automatic identification of the pipeline corresponding to the pipe length label is realized.
By executing the steps, the pipeline marking identification method provided by the embodiment of the invention determines a pipeline belonging to the pipeline length marking by using the distance between the pipeline length marking and the pipeline, and extracts the pipeline set for matching according to the pipeline length value marked by the pipeline length along the connecting direction of the pipeline, so that the automatic identification of the pipeline corresponding to the pipeline length marking is realized, the pipeline marking identification efficiency is improved, the problem that the pipeline marking is easy to be identified by mistake in manual identification is avoided, the pipeline marking identification result accuracy is improved, and the user experience is further improved.
Specifically, in an embodiment, the step S103 specifically includes the following steps:
step S301: and acquiring the distance between each pipe length label and the current pipeline and the pipe length value of each pipe length label.
In the figure, the line segment between the tube length a and the tube length B is the target line, and the tube length values corresponding to the tube length a and the tube length B are 24.35m and 18.40m, respectively.
Step S302: and respectively inputting the distance between each pipe length label and the current pipeline and the pipe length value of each pipe length label into a pipeline identification model to obtain a prediction score corresponding to each pipe length label.
Specifically, as shown in fig. 2, it is assumed that the shortest distance from the central point ptA of the pipe length a to the target pipeline is MinA, and the pipe length value is ALength; the shortest distance from the central point ptB of the pipe length B to the target pipeline is MinB, and the pipe length value is BLength; the actual length of the target pipeline is ActualLength; setting the weight value: a pipe distance weight wdsi, a pipe length weight ldsi, where the sum of wdsi and ldsi equals 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 this.
Wherein, the pipeline identification model is expressed by the following formula:
M＝MinN*wDis+(NLength-ActualLength)*lDis
and M is the prediction score of the pipeline identification model, MinN is the shortest distance between the Nth pipe length and the target pipeline, and NLength is the pipe length value marked by the Nth pipe length.
A predicted score for tube length a ═ MinA × wDis + (ALength-actualelength) × lDis;
the predicted score for tube length B is MinB wDis + (BLength-actullength) lDis.
Step S303: and determining the tube length label with the highest prediction score as the current tube length label corresponding to the current pipeline.
Illustratively, assuming that the prediction score of the tube length B is greater than the prediction score of the tube length a in fig. 2, the tube length B is determined as 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 marking identification result is ensured. The embodiment of the invention can adapt to different drawing habits of CAD drawings, has wide application range and strong flexibility, and further improves the user experience.
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.
Exemplarily, as shown in fig. 3, the number above the pipeline is the pipeline number corresponding to each pipeline, and the value below the pipeline is the actual length of the pipeline corresponding to each pipeline, and assuming that No. 3 pipeline is matched with the L6 pipeline length label, the pipeline is searched from one direction of the connection of No. 3 pipeline until a set of all pipelines with a small margin 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 construction engineering drawing and the scale corresponding to the target construction engineering drawing.
Specifically, the CAD drawing is drawn according to a fixed scale, and the actual length of the dimension on the CAD drawing can be obtained by the fixed scale, for example, assuming that the scale is 1:5000, it means that 1cm on the CAD drawing represents actual 50m, and if the total length of all pipelines in the pipeline set on the CAD drawing is 10cm, the actual length of the pipeline set is 500m, and the like.
Step S403: and screening the pipeline sets with the actual lengths equal to the pipe length value marked by the first pipe length based on the actual lengths of the pipeline sets.
Illustratively, as shown in FIG. 3, looking from pipeline # 3, say, to the left, find pipe # 3, # 2, overall length 5, and then looking in one direction for another connection, find pipe # 3, # 4, # 5, overall length 6. Since it is determined that the right side is more in line with the actual value, the pipeline sets 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 proportion scale and the total length of the pipeline set on the CAD drawing, the matching relation between the pipeline length mark and the pipeline set can be accurately matched by comparing the pipeline length value of the pipeline length mark with the actual length, the accuracy of the final pipeline length mark identification result is further improved, and the user experience is improved.
Specifically, in an embodiment, before the step S104, the pipeline tag identification method further includes the following steps:
step S41: and acquiring a first length of the first pipeline in the target construction engineering drawing and a scale corresponding to the target construction engineering drawing.
Wherein, 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 of the first pipeline is calculated in a manner similar to the total length of the pipeline set, and is not described herein again.
Step S43: judging whether the first actual length is smaller than the pipe length value marked by the first pipe length; when the first actual length is smaller than the pipe length value marked by the first pipe length, executing the step S104; when the actual length is equal to the first pipe length value, matching the first pipe length label with the first pipeline.
In practical application, a situation that one pipe length label corresponds to one pipeline may exist, so that the identification of the pipe length label of the single pipeline can be directly realized by comparing whether the actual length of the single pipeline is matched with the pipe length value of the pipe length label or not, subsequent steps do not need to be executed, and the identification efficiency of the pipe length label is further improved.
Specifically, in an embodiment, the above pipeline label identification method 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 the pipe diameter label information, step S107 is executed. When the first pipe length label does not contain pipe diameter label information, the pipe diameter label information contained in the first pipe length label is matched with the pipeline set. . In practical application, the pipeline marking comprises pipe length marking and pipe diameter marking, automatic matching of pipe diameter marking and the pipeline is achieved, automatic matching of complete pipeline marking and the pipeline is achieved, pipeline marking identification efficiency is further improved, and user experience is improved.
Step S107: and acquiring the pipe diameter labels in the area to be identified of the target architectural engineering drawing.
In practical application, in some CAD drawings, the pipe length mark and the pipe diameter mark are in different mark frames, so that the identification of the pipe diameter mark is completely realized, and the matching of the pipe diameter mark and the pipe diameter is also needed to be realized. And marking the independent pipe diameter on the CAD drawing as a marking frame with a pipe diameter value.
Step S108: and respectively calculating the distance between each pipe diameter and each pipeline marked in the area to be identified.
Specifically, in step S108, the central point of each pipe diameter label is obtained; 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. Thus, the distance between each pipe diameter label and different pipes is determined according to the distance from the point to the line.
Step S109: and determining a second pipeline corresponding to each pipe diameter label based on the distance from each pipe diameter label to each pipeline in the area to be identified.
The pipe diameter mark is usually arranged near the corresponding pipeline during CAD drawing design, and the closer the pipe diameter mark is to the pipeline, the higher the possibility that the pipe diameter value of the pipe belongs to the pipe diameter mark is, so that one pipe belonging to the pipe diameter mark can be determined according to the distance between the pipe diameter mark and the pipe.
Step S110: and acquiring a first pipe diameter label corresponding to any pipe line in the pipe line set based on the second pipe line corresponding to each pipe diameter label.
Specifically, any one of the pipelines in the pipeline set may correspond to a pipe diameter label, and since each pipeline in the pipeline set belongs to a pipe length label and a plurality of sequentially connected pipelines having 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 by the pipe diameter label of any one pipeline in the pipeline set. Thereby further improved the discernment efficiency of pipe diameter mark, improved user and used experience.
Step S111: and matching the first pipe diameter label with the pipeline set.
Specifically, a matching relation can be established between the pipe diameter value corresponding to the first pipe diameter label and the serial number of each pipeline in the pipeline set, so that automatic identification of the pipe diameter label is realized, full-automatic identification of the pipeline label is realized, the pipeline identification efficiency is further improved, and the user experience is improved.
In addition, in practical application, a pipeline label which is parallel to the pipeline and is closest to the pipeline can be found through the current pipeline, whether the pipeline label comprises a diameter value and a length value is judged, the length value is consistent with the actual length of the current pipeline in a CAD drawing, and if the pipeline label comprises the diameter value and the length value, and the length value is consistent with the actual length of the current pipeline in the CAD drawing, the pipeline label is directly matched with the current pipeline.
Illustratively, as shown in FIG. 4, assume that the total tube length of tubes No. 1, 2, and 3 is 41m, the tube diameters are all 300mm, and the total tube length of tubes 4 and 5 is 35m, the tube diameters are all 500 mm. In the manner of steps S301 to S303, pipeline 2 can be matched to pipe diameter DN300, pipeline 3 can be matched to pipe length L41m, pipeline 4 can be matched to pipe diameter DN500, and pipeline 5 can be matched to pipe length L35 m. Then, finding all pipelines matched with the pipe length, namely 3 and 4, finding a pipe set with the pipe length of No. 3 marked as 41m, finding a pipe set with the pipe length sum of other pipes (the pipes marked with the pipe lengths) connected with the No. 3 pipe being the nearest 41m, namely finding the pipe set with the total length of No. 1, No. 2 and No. 3 pipes being the closest 41m, finding the pipe marked with the pipe diameter from the found pipes, and assigning the pipe diameter DN300 to the pipes 1 and 3 without the pipe diameter.
In practical application, the pipeline and the independent pipe length, the independent pipe diameter, the pipe length and the pipe diameter can be matched, after matching, the independent pipe diameter and the independent pipe length matched with the same pipeline are combined, then all the pipeline marks matched with the pipeline can be obtained, the optimal pipeline path is searched through the marked value of the pipe length, the pipeline length is closest to the pipe length mark, the pipe length mark is considered to be given to the pipes, then the pipe marks matched with the pipe diameters are found on the pipes, and then the pipe diameters are given to the pipes without the pipe diameters, so that the pipe diameters of the pipeline are found. If the pipe with the pipe diameter mark is not found, default pipe diameter and the like are adopted, and the invention is not limited by the method.
In addition, in practical application, because only the pipeline label corresponding to the main pipeline needs to be identified, and the branch pipeline does not need to be identified, the embodiment of the present invention further provides a way of determining whether the pipeline is the main pipeline or the branch pipeline, which specifically includes the following processes:
illustratively, as shown in fig. 5, there are 4 lines, main lines 1, 2, 3, and branch lines 1, 4. The method for judging whether the current pipeline is a branch pipeline comprises the steps of obtaining the starting point position and the end point position of the current pipeline, constructing a three-dimensional bounding box by adding a fault tolerance through the starting point position, extracting all primitives intersected with the bounding box, judging the position relation between the upper point of the current pipeline and the primitives, and if other pipelines except the current pipeline can be found, indicating that the starting point position of the current pipeline is connected with other pipelines. Similarly, whether the end point position of the current pipeline is connected with other pipelines is judged, and if the starting point and the end point are both connected with the pipelines, the current pipeline is considered not to be the branch pipeline but to be the main pipeline.
