[0020] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present application.

[0021] It should be noted that the terms "first", "second", etc. in the specification and claims of the present application and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the data used in this way can be interchangeable where appropriate, so that the embodiments of the present application described herein can be implemented in an order other than those illustrated or described herein.

[0022] The method embodiments provided in the embodiments of the present application can be executed in a computer terminal or a similar computing device. Taking running on a computer terminal as an example, Figure 1 1 is a hardware structure block diagram of a computer terminal of a PAM4 signal modulation method according to an embodiment of the present application. Figure 1 As shown, the computer terminal may include one or more ( Figure 1 Only one is shown in the figure) a processor 102 (the processor 102 may include but is not limited to a processing device such as a microprocessor MCU or a programmable logic device FPGA) and a memory 104 for storing data, wherein the above-mentioned computer terminal may also include a transmission device 106 and an input / output device 108 for communication functions. It can be understood by those skilled in the art that Figure 1 The structure shown is only for illustration and does not limit the structure of the above-mentioned computer terminal.

[0023] The memory 104 can be used to store computer programs, for example, software programs and modules of application software, such as the computer program corresponding to the method for determining the mapping relationship in the embodiment of the present application. The processor 102 executes various functional applications and data processing by running the computer program stored in the memory 104, that is, to implement the above method. The memory 104 may include a high-speed random access memory, and may also include a non-volatile memory, such as one or more magnetic storage devices, flash memory, or other non-volatile solid-state memory.

In one example, the transmission device 106 includes a network adapter (Network Interface Controller, referred to as NIC), which can be connected to other network devices through a base station so as to communicate with the Internet. In one example, the transmission device 106 can be a radio frequency (RF) module, which is used to communicate with the Internet wirelessly.

[0025] Optionally, as an optional implementation, as Figure 2 As shown, the segmentation methods of CAD graphics include:

[0026] S202, reading segmentation data associated with the initial CAD graphic to be segmented from the initial CAD graphic, wherein the segmentation data is used to indicate the number of first segments associated with the initial CAD graphic;

[0027] S204, performing initial segmentation on the initial CAD graphic to obtain a second number of segmented first CAD graphics;

[0028] S206: When the second number of segments is inconsistent with the first number of segments, correct and segment the first CAD figure to obtain a second CAD figure with the first number of segments.

[0029] Optionally, in this embodiment, the initial CAD drawing to be segmented may be but is not limited to a CAD drawing displayed in a CAD client, and may be but is not limited to including a beam component, wherein a beam component may be but is not limited to a plurality of beam segments roughly located on a line in the CAD drawing.

[0030] Optionally, in this embodiment, the segmented data associated with the initial CAD graphic can be but is not limited to being determined based on user text information associated with the initial CAD graphic, wherein the user can, but is not limited to, input the user text information associated with the initial CAD graphic when creating the initial CAD graphic, and can, but is not limited to, include the graphic name information, graphic data information and segmented data of the initial CAD graphic.

[0031] To further illustrate, Figure 3 As shown, Figure 3 What is displayed in the figure is user text information associated with a certain CAD graphic, wherein the user text information includes "L2(4)250x600", "L2" in the user text information is used to indicate the graphic name of the CAD graphic, "4" is used to indicate the first segment number associated with the CAD graphic, and "250x600" is used to indicate the graphic data information associated with the CAD graphic.

[0032] It can be understood that the segmentation data is used to indicate the first segmentation quantity associated with the initial CAD graphic, and the first segmentation data is the number of segmentation results that the user expects to obtain after the initial CAD graphic is segmented.

[0033] Optionally, in this embodiment, the initial CAD graphic is initially segmented to obtain a second number of segmented first CAD graphics, and the recognition and segmentation of the CAD graphic may be completed according to, but is not limited to, a general recognition logic.

[0034] Optionally, in this embodiment, when the second number of segments is consistent with the first number of segments, it is determined that it is reasonable to perform the first initial segmentation on the initial CAD drawing, and the first CAD drawing of the second number of segments is determined as the second CAD drawing of the first number of segments.

[0035] Optionally, in this embodiment, when the second number of segments is inconsistent with the first number of segments, it is determined that the first initial segmentation of the initial CAD drawing is unreasonable, and segmentation correction is required based on the first CAD drawing obtained by the first initial segmentation to obtain a second CAD drawing with the first number of segments.

[0036] Optionally, in this embodiment, the case where the second segment number is inconsistent with the first segment number may include, but is not limited to, a case where the second segment number is less than the first segment number and a case where the second segment number is less than the first segment number.

[0037] It is understandable that, when the second number of segments is less than the first number of segments, it is determined that the segmentation result obtained by the first initial segmentation indicates that the number of segments is small, and further splitting and segmenting processing is required based on the first CAD figure.

[0038] Also, when the second segment number is smaller than the first segment number, it is determined that the segmentation result obtained by the first initial segmentation indicates that the number of segments is too large, and further merging and segmenting processing is required based on the first CAD drawing.

[0039] Through the embodiment provided by the present application, after the initial CAD graphic is initially segmented to obtain the first CAD graphic with the second number of segments, the first CAD graphic with the second number of segments is verified based on the first number of segments indicated by the segmentation data associated with the initial CAD graphic. If the second number of segments is inconsistent with the first number of segments, the first CAD graphic is corrected and segmented to obtain the second CAD graphic with the first number of segments. In this way, the defect of inaccurate segmentation results caused by inaccurate recognition of general recognition logic is avoided, thereby achieving the technical effect of improving the segmentation accuracy of CAD graphics.

[0040] As an optional solution, when the second number of segments is inconsistent with the first number of segments, correcting and segmenting the first CAD drawing to obtain the second CAD drawing with the first number of segments includes:

[0041] In a case where the second segment number is less than the first segment number, determining at least one first node style template matching a first graphic area of ​​the first CAD graphic from a node style template set, wherein the first graphic area corresponds to a segmentation result of the first CAD graphic;

[0042] Using the at least one first node style template, splitting the first graphic area to obtain the first number of segmented second CAD graphics;

[0043] In a case where the second number of segments is greater than the first number of segments, determining at least one second node style template matching a second graphic region of the first CAD graphic from the node style template set, wherein the second graphic region corresponds to at least two segmentation results of the first CAD graphic;

[0044] The second graphic areas are merged using the at least one second node style template to obtain the second CAD graphics of the first number of segments.

[0045] Optionally, in this embodiment, when the second number of segments is less than the first number of segments, it is determined that the segmentation result obtained by the first initial segmentation indicates that the number of segments is small, and further splitting and segmenting processing is required based on the first CAD figure.

[0046] It should be noted that before the splitting and segmenting process is performed, at least one first node style template matching the first graphic area of ​​the first CAD graphic is determined from the node style template set.

[0047] Optionally, in this embodiment, the node style template set is a pre-established standard template for splitting or merging. It is understandable that, when there is a graphic area consistent with a certain node style template in the first CAD graphic, the graphic area can be split or merged according to the splitting or merging requirements with reference to the node position information of the node style template, but is not limited to.

[0048] To further illustrate, Figure 4 As shown, the pre-established node style template set includes a1-type node style template, a2-type node style template, a3-type node style template, and, as Figure 5 As shown, the b1-type node style template, b2-type node style template, and b3-type node style template included in the pre-established node style template set. Among them, different types of node style templates correspond to different connection types and / or connection methods, and different types of node style templates correspond to different priorities, that is, the node style template with a high priority is used first to match the first CAD drawing to determine whether it is the node style template required for the current splitting or merging requirements of the first CAD drawing. To further illustrate, as shown in the a1-type node style template, beams 1 and 2 in the horizontal direction on the left and right sides of the node are beam segments to be corrected.

[0049] Optionally, in this embodiment, when at least one first node style template matching the first graphic area of ​​the first CAD graphic is determined from the node style template set, the first graphic area is split using the at least one first node style template to obtain the second CAD graphic with the first number of segments.

[0050] It should be noted that after each match, a splitting process is performed to obtain the number of segments included in the new CAD graphic plus one, and on this basis, it is determined whether the number of segments of the new CAD graphic is consistent with the number of segments of the first graphic. If they are consistent, the splitting correction is completed to obtain the second CAD graphic with the first number of segments. If they are inconsistent, based on the new CAD graphic, the next node style template is matched with reference to the priority, and the next splitting process is performed.

[0051] Also, when the second segment number is smaller than the first segment number, it is determined that the segmentation result obtained by the first initial segmentation indicates that the number of segments is too large, and further merging and segmenting processing is required based on the first CAD drawing.

[0052] It should be noted that before the splitting and segmenting process is performed, at least one second node style template matching the second graphic area of ​​the first CAD graphic is determined from the node style template set.

[0053] Optionally, in this embodiment, the node style template set is a pre-established standard template for splitting or merging. It is understandable that, when there is a graphic area consistent with a certain node style template in the first CAD graphic, the graphic area can be split or merged according to the splitting or merging requirements with reference to the node position information of the node style template, but is not limited to.

[0054] Optionally, in this embodiment, when at least one second node style template matching the second graphic area of ​​the first CAD graphic is determined from the node style template set, the second graphic area is merged using the at least one second node style template to obtain the second CAD graphic of the first number of segments.

[0055] It should be noted that after each match, a merge process is performed to obtain the number of segments included in the new CAD graphic minus one, and on this basis, it is determined whether the number of segments of the new CAD graphic is consistent with the number of segments of the first CAD graphic. If they are consistent, the merge correction is completed to obtain the second CAD graphic with the first number of segments. If they are inconsistent, based on the new CAD graphic, the next node style template is matched with reference to the priority, and the next merge process is performed.

[0056] Through the embodiments provided by the present application, if the number of second segments is less than the number of first segments, the first CAD drawing is split and corrected to obtain the second CAD drawing with the first number of segments; if the number of second segments is greater than the first number of segments, the first CAD drawing is merged and corrected to obtain the second CAD drawing with the first number of segments; in this way, the defect of inaccurate segmentation results caused by inaccurate recognition of general recognition logic is avoided, thereby achieving the technical effect of improving the segmentation accuracy of CAD graphics.

[0057] As an optional solution, determining at least one first node style template matching the first graphic area of ​​the first CAD graphic from the node style template set includes:

[0058] Acquire a first node style template with the highest splitting priority from the node style templates;

[0059] Use the first node style template with the highest priority to compare with each segmentation result from left to right of the first CAD graphic to match and determine the first graphic area with the same style;

[0060] The step of using the at least one first node style template to split the first graphic area to obtain the first number of segmented second CAD graphics includes:

[0061] Determine, based on the first node position of the first node style template with the highest priority, the second node position corresponding to the first graphic area;

[0062] Splitting the first graphic area at the second node position to obtain a third CAD graphic with a third number of segments;

[0063] When the number of the third segments is less than the number of the first segments, continue to obtain the unused first node style template with the highest splitting priority from the node style template, and split the third CAD figure until the second CAD figure with the first number of segments is obtained;

[0064] In a case where the third number of segments is equal to the first number of segments, the third CAD figure is determined as the second CAD figure.

[0065] Optionally, in this embodiment, the first node style template with the highest splitting priority is first obtained from the node style templates, and the first node style template with the highest priority is used to compare with each segmentation result from left to right of the first CAD graphic to match and determine the first graphic area with consistent style.

[0066] It can be understood that the first node style template is taken out in sequence according to the splitting priority order, and compared with each node of the current first CAD graphic from left to right. When the styles match, the splitting is performed.

[0067] It should be noted that after each match, a splitting process is performed to obtain the number of segments included in the new CAD graphic plus one, and on this basis, it is determined whether the number of segments of the new CAD graphic is consistent with the number of segments of the first graphic. If they are consistent, the splitting correction is completed to obtain the second CAD graphic with the first number of segments. If they are inconsistent, based on the new CAD graphic, the next node style template is matched with reference to the priority, and the next splitting process is performed.

[0068] As an optional solution, determining at least one second node style template matching the second graphic area of ​​the first CAD graphic from the node style template set includes:

[0069] Acquire a second node style template with the highest merging priority from the node style templates;

[0070] Using the second node style template with the highest priority, compare with at least two segmentation results of the second CAD graphic from left to right, so as to match and determine the second graphic area with the same style;

[0071] The step of using the at least one second node style template to merge the second graphic areas to obtain the first segmented number of second CAD graphics includes:

[0072] Determining a fourth node position corresponding to the second graphic area based on the third node position of the second node style template with the highest priority;

[0073] Merging the second graphic regions at the fourth node position to obtain fourth CAD graphics of a fourth number of segments;

[0074] When the number of the fourth segments is greater than the number of the first segments, continue to obtain unused second node style templates with the highest merging priority from the node style templates, and perform merging processing on the fourth CAD graphics until the second CAD graphics with the first number of segments are obtained;

[0075] When the fourth segment number is equal to the first segment number, the fourth CAD figure is determined as the second CAD figure.

[0076] Optionally, in this embodiment, a second node style template with the highest splitting priority is first obtained from the node style template, and the second node style template with the highest priority is used to compare with every two segmentation results from left to right of the second CAD graphic to match and determine the second graphic area with consistent style.

[0077] It can be understood that the second node style templates are taken out in sequence according to the splitting priority order, and compared with the nodes of the current second CAD graphic from left to right. When the styles match, the merge is performed.

[0078] It should be noted that after each match, a merge process is performed to obtain the number of segments included in the new CAD graphic minus one, and on this basis, it is determined whether the number of segments of the new CAD graphic is consistent with the number of segments of the first CAD graphic. If they are consistent, the merge correction is completed to obtain the second CAD graphic with the first number of segments. If they are inconsistent, based on the new CAD graphic, the next node style template is matched with reference to the priority, and the next merge process is performed.

[0079] As an optional solution, the step of reading the segmentation data associated with the initial CAD graphic to be segmented includes:

[0080] Acquire user text information associated with the initial CAD graphic, wherein the user text information includes graphic name information, graphic data information and the segmented data of the initial CAD graphic;

[0081] The segmented data is read from the user text information.

[0082] Optionally, in this embodiment, the segmented data associated with the initial CAD graphic can be but is not limited to being determined based on user text information associated with the initial CAD graphic, wherein the user can, but is not limited to, input the user text information associated with the initial CAD graphic when creating the initial CAD graphic, and can, but is not limited to, include the graphic name information, graphic data information and segmented data of the initial CAD graphic.

[0083] To further illustrate, Figure 3 As shown, Figure 3 What is displayed in the figure is user text information associated with a certain CAD graphic, wherein the user text information includes "L2(4)250x600", "L2" in the user text information is used to indicate the graphic name of the CAD graphic, "4" is used to indicate the first segment number associated with the CAD graphic, and "250x600" is used to indicate the graphic data information associated with the CAD graphic.

[0084] As an optional solution, the above CAD graphics segmentation method is applied to a scenario where the program graphics recognition results are corrected according to user text information. According to different node drawing methods of the drawings, several node style templates are established as comparison standards, such as Figure 4 and Figure 5 As shown. Further determine the matching between the proposed corrected position node drawing method and the standard node style and determine the priority of the standard node style participating in the comparison.

[0085] For example, Figure 4 and Figure 5 As shown, an optional merging priority may be but not limited to a1, a2, b1, b2; an optional splitting priority may be but not limited to b3, b2, a1, a2.

[0086] Optionally, in this embodiment, the program completes the segmentation of the building structure graphic recognition according to the general recognition logic, and then intelligently corrects the initial segmentation result by comparing the standard node style based on the text information (segmentation information) marked by the user. If the number of segments is consistent after several corrections, the correction is completed. If the number of segments is still inconsistent, the correction is abandoned.

[0087] Specifically, an optional operation process includes:

[0088] The program reads DWG architectural structure drawings;

[0089] The program segments a beam according to a general algorithm;

[0090] Determine if the number of program segments is inconsistent with the number of user annotations, and execute the correction logic (split or merge). Take the example of program segment number < user annotation number, and split the program segmentation result. Take out the standard node style in order of split priority, and compare it with the nodes of the current beam from left to right. When the style matches, split; if b3, b2, and a3 do not match the node with the same style, skip it. Figure 6 As shown, type a2 can match nodes with the same style and split (assuming the splitting priority is b3, b2, a3, a2). It can be understood that after recognizing the DWG building structure graphics, the program reads the DWG building structure graphics; recognizes and parses the graphics according to the general algorithm to obtain segmentation information; traverses each beam to determine whether the program segmentation result is consistent with the number of segments marked by the user.

[0091] If they are consistent, no correction is required; use relevant modification tools to manually adjust the program recognition results; if they are inconsistent, enter the correction process.

[0092] In the correction process, if the number of initial program segments is greater than the number of user text annotations, the beam segments need to be merged at the nodes. The node templates in the standard node style queue are taken out in order of merging priority, and compared with the drawing methods of the current beam nodes. If the styles are consistent, the beam segments are merged at this node; after a node style is compared and modified, the number of segments of the current beam is compared to the number of user annotations. If they are consistent, the correction is ended. If they are inconsistent, the next node style is taken out for comparison and merge correction; after all node styles in the standard node style queue are compared, if the number of segments is still inconsistent, the correction is abandoned.

[0093] In the correction process, if the number of initial program segments is less than the number of user text annotations, the beam segment needs to be split at the node. The process is the same as above. The nodes in the standard node style queue are taken in turn according to the splitting priority order for comparison and splitting.

[0094] Through the embodiments provided by this application, the accuracy of program recognition is improved; the diversity of professional understanding of different users is taken into consideration, and the applicability of the program is improved. The general program recognition results are automatically optimized to make the program recognition results as consistent as possible with the user's understanding, solving the contradiction between the fixed program algorithm results and the diverse user needs in the segmentation problem of architectural structure drawing recognition.

[0095] It is understandable that in the specific implementation of this application, related data such as user information is involved. When the above embodiments of this application are applied to specific products or technologies, user permission or consent is required, and the collection, use and processing of relevant data need to comply with relevant laws, regulations and standards of relevant countries and regions.
