It should be understood that the following drawings only show certain embodiments of the present application and therefore should not be regarded as limiting the scope. For ordinary technicians in this field, other related drawings can be obtained based on these drawings without paying creative work.

[0026] In order to better explain the present invention and facilitate understanding, the present invention is described in detail below through specific implementation modes in conjunction with the accompanying drawings.

[0027] At present, the invention with application number 202311389986.1 discloses a beam component identification method and electronic device, which has sorted out all the marking information, and the ownership of all the markings has been preliminarily defined. However, since there is a situation where a centralized marking corresponds to multiple continuous beams, in order to accurately find the marking information corresponding to each beam, it is necessary to further match the cross-beam information.

[0028] Based on this, the present application proposes a matching method and device for span-beam marking. First, the position relationship is used to judge all the beams, and the topological relationship between beams and beams and walls is constructed. Secondly, special forms of beams are identified and processed in turn. Then, the regular matching method can be used to parse all the marked numbering information to obtain the section height and number of spans. In conjunction with the deep learning recognition method, the image clustering method and the sequential grouping logic, all beams are assigned numbers and sections in turn. Then, after obtaining the section information, the special forms of beams are judged in turn to determine whether they will affect the judgment of the beam components. Then, the beam numbers and section information of the beams that may be erroneous are grouped and iteratively processed until the number information no longer changes or a fixed number of iterations is reached, thereby achieving automatic matching of span-beam and beam markings including beam numbers, thereby greatly improving work efficiency and accuracy.

[0029] In order to better understand the above technical solution, exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present invention are shown in the accompanying drawings, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments described herein. On the contrary, these embodiments are provided to enable a clearer and more thorough understanding of the present invention and to fully convey the scope of the present invention to those skilled in the art.

[0030] See also Figure 1 , Figure 1 FIG. 1 is a flow chart showing a method for matching a beam span annotation provided by an embodiment of the present application. Figure 1 As shown, the matching method can be executed by an electronic device, and the specific device of the electronic device can be set according to actual needs, and the embodiments of the present application are not limited thereto. For example, the electronic device can be a computer or a server. Specifically, the matching method includes:

[0031] Step S110, clustering all beams in the architectural drawings using a hierarchical clustering method to obtain a plurality of beam groups, wherein each of the plurality of beam groups includes a plurality of continuous span beams, and there is a span beam marked by its corresponding span beam annotation in each of the plurality of span beams in each beam group, and each span beam annotation is used to mark all span beams in the corresponding beam group, and the plurality of span beams in each beam group are located on a line, and the spacing between any two adjacent span beams in the plurality of span beams in each beam group is less than a preset spacing, and any two adjacent span beams are divided by a wall.

[0032] It should be noted here that for multiple continuous span beams belonging to the same beam group, when drawing, the draftsman will mark one of the multiple continuous span beams in the same beam group, and other span beams in the same beam group except the marked span beam do not need to be marked. In other words, the span beam marking is used to mark all span beams in the same beam group, that is, the span beam marking is a centralized marking. Among them, each span beam marking can include numbering information and cross-sectional information, and the numbering information may include quantity numbering information for indicating how many span beams there are in the corresponding beam group, and the cross-sectional information includes beam height information. For example, when the span beam marking includes KL4(3)200×670, the KL4(3) is the numbering information, and the quantity numbering information 3 indicates that there are 3 span beams in the corresponding beam group; the 200×670 is the cross-sectional information, and 670 indicates the beam height of all span beams in the corresponding beam group.

[0033] In addition, the remaining information of the span beam marking except the quantity number information is called non-quantity number information.

[0034] To facilitate understanding of step S110, a specific embodiment is used to describe it below.

[0035] Specifically, before matching the span annotations of beams, it is necessary to cluster beams that may have the same number, and multiple span beams belonging to the same group need to meet the following conditions: multiple continuous span beams in the same beam group are located on a line (for example, a horizontal line or a vertical line), and the spacing between any two adjacent span beams in the multiple span beams in the same beam group is less than a preset spacing, and any two adjacent span beams in the multiple span beams in the same beam group are separated by a wall,

[0036] Therefore, this type of beam complies with the principle of assigning span-beam annotations, so it needs to be grouped together to facilitate the subsequent assignment of span-beam annotations.

[0037] On the basis of satisfying the above conditions, the beam clustering grouping method of the present application is implemented by adopting a hierarchical clustering method, which can divide all beams into different combinations by gradually merging single point clusters.

[0038] Step S120, determining the span beam label corresponding to each beam group, wherein the span beam label includes quantity number information and non-quantity number information for indicating the number of span beams in the corresponding beam group.

[0039] Specifically, since there is a span beam marked by the span beam annotation among the multiple span beams in each beam group, it can be determined whether the quantity number information and the span beam quantity of all the span beams in the corresponding beam group are consistent based on the quantity number information in the span beam annotation. If they are consistent, it indicates that the identified span beam annotation belongs to the beam annotation of the corresponding beam group; if they are not consistent, it indicates that the identified span beam annotation does not belong to the beam annotation of the corresponding beam group.

[0040] Step S130, based on the span beam annotation corresponding to each beam group, non-quantity number information is assigned to the other span beams in each beam group except the span beams marked by the corresponding span beam annotation in accordance with the preset annotation assignment principle.

[0041] Specifically, after determining the span-beam annotation corresponding to each beam group, the span-beam annotation is matched for each beam group in turn, and the span-beam annotation is assigned to each span-beam in each beam group in turn according to the preset annotation assignment principle. For example, the numbering information in the span-beam annotation of the current beam group is read, and the number of spans corresponding to the span-beam annotation is obtained according to the regular matching method, and other information in the numbering information except the quantity number information can be assigned to the other spans of the current beam group except the spans marked by the corresponding span-beam annotation in turn, and after the information is assigned to other spans, the other information in the span-beam annotation can also be assigned to the other spans of the current beam group except the spans marked by the corresponding span-beam annotation in turn. Among them, the current beam group is any one of the multiple beam groups; the preset annotation assignment principle is the principle from left to right or the principle from bottom to top.

[0042] And, after obtaining the span beam marking of the current beam group, non-quantity number information is sequentially assigned to the other span beams of the current beam group except the span beam marked by the corresponding span beam marking from left to right or from bottom to top, and the conditions that need to be met for assigning the non-quantity number information are:

[0043] The principle for assigning non-quantity number information is from the leftmost span to the rightmost span of the beam group, or from the bottommost span to the topmost span of the beam group;

[0044] The number of the beam marked by the span beam annotation must be the number in the span beam annotation;

[0045] The beam groups corresponding to each number are continuous.

[0046] Further, after step S130, the matching method further includes: constructing a beam topological relationship of each beam among all beams based on the position relationship of all beams and all walls in the architectural drawings; wherein the beam topological relationship of each beam records the beams or walls that intersect or connect with it; identifying special beams among all beams based on the beam topological relationship of each beam to obtain special beam identification results; wherein the special beams include cross beam structures or T-beam structures; based on the special beam identification results, judging whether there are interrupted span beams in the current beam group; wherein the current beam group is any one of the multiple beam groups; if it is determined that there are interrupted span beams in the current beam group, the interrupted span beams in the current beam group are divided into multiple span beams to obtain an updated beam group; based on the span beam annotation corresponding to each beam group, each span beam in the updated beam group is assigned a span beam annotation in turn according to a preset annotation assignment principle.

[0047] In order to facilitate understanding of the above technical solution, it is described below through specific embodiments.

[0048] Specifically, first, based on the positional relationship of all beams and all walls in the architectural drawings, the beam topology relationship of each beam among all beams is constructed, wherein the beam topology relationship of each beam records the beams or walls that intersect or connect with it.

[0049] Secondly, a beam component identification method and electronic device disclosed in the invention with application number 202311389986.1 have found all the beams, but some beams exist in the form of special beams such as cross beam structures or T-beam structures. This type of special beam may be interrupted. Among them, the interruption of this application refers to identifying a beam as multiple beams. For example, a beam in the horizontal and vertical directions was found through the detection method, but the beam in the horizontal direction is actually two beams, and the beam in the vertical direction is actually one beam. Because the beam heights are different, the beam with a higher height usually serves as a support for the beam with a lower height, so the special beam needs to be further identified and processed to obtain more accurate beam component information.

[0050] And, the identification process of the special beam is as follows: when the beam topology relationship of each beam is obtained, it can be determined whether the middle area or end area of ​​each beam intersects with other beams according to the beam topology relationship of each beam, and all intersecting beams are recorded to obtain the special beam identification result. In other words, the present application determines whether it conforms to the cross beam structure or the T-beam structure by the spatial position relationship.

[0051] Again, after matching the non-quantity number information, each beam has a corresponding non-quantity number information. However, due to the existence of the special beam form mentioned above, this type of beam form is prone to non-quantity number information matching errors. Therefore, this type of beam needs to be further processed to determine whether it is possible that there are actually multiple beams (for example, two beams).

[0052] After the initial assignment process in step S130, each beam has corresponding reinforcement and cross-section information. The situations where a special beam is interrupted are mainly the following two situations:

[0053] The beam intersecting the span beam is a cantilever beam. For example, if the number in the marking of the beam intersecting the span beam is XL, the beam intersecting the span beam is determined to be a cantilever beam;

[0054] The height of the beam intersecting the span beam is greater than the beam height of the span beam. For example, the beam height in the span beam annotation of the span beam and the beam height in the annotation of the beam intersecting the span beam are read, and then the two beam heights are compared to determine that the height of the beam intersecting the span beam is greater than the beam height of the span beam.

[0055] The span beams that meet the above conditions will be interrupted.

[0056] Finally, all special beams are screened. After the special beams are interrupted, the interrupted span beams in the current beam group are divided into multiple span beams to obtain an updated beam group, and step S130 is repeatedly performed on the updated beam group. The repetitive process can be repeated multiple times until the stop condition is met, and the loop is stopped. The stop condition is that no new special beams are interrupted or a fixed number of iterations is reached.

[0057] Therefore, with the help of the above-mentioned technical scheme, the present application clusters all the beams in the architectural drawings by adopting a hierarchical clustering method to obtain multiple beam groups, and then determines the span-beam marking corresponding to each beam group, and based on the span-beam marking corresponding to each beam group, according to the preset marking assignment principle, assigns non-quantity numbering information to the other span beams in each beam group except the span beams marked by the corresponding span-beam marking, thereby realizing automatic matching of span beams and beam markings including beam numbers, thereby greatly improving work efficiency and accuracy.

[0058] It should be understood that the above-mentioned matching method for span beam marking is only exemplary, and those skilled in the art may make various modifications based on the above-mentioned method, and the modified scheme also falls within the protection scope of the present application.
