Description

Technical Field

[0001] The present application relates to the field of computers, and in particular to a method, device, storage medium and electronic device for acquiring a three-dimensional model. Background Art

[0002] In the scenario of acquiring three-dimensional models, two-dimensional drawings are usually converted into three-dimensional models by manual conversion, but this conversion method is inefficient, especially when faced with a large number of two-dimensional drawings.

[0003] If the two-dimensional drawings are converted into three-dimensional models by automatic conversion, it cannot be guaranteed that each pixel in the two-dimensional drawings can be successfully converted into three-dimensional pixels. If the conversion into three-dimensional pixels is not successful or the conversion into wrong three-dimensional pixels is not successful, it will increase the correction steps, which will lead to the problem of low efficiency in obtaining three-dimensional models. Therefore, there is a problem of low efficiency in obtaining three-dimensional models.

[0014] According to another aspect of the embodiments of the present application, a computer program product or a computer program is provided, the computer program product or the computer program including computer instructions, the computer instructions being stored in a computer-readable storage medium. A processor of an electronic device reads the computer instructions from the computer-readable storage medium, and the processor executes the computer instructions, so that the electronic device executes the above three-dimensional model acquisition method.

[0015] According to another aspect of an embodiment of the present application, there is also provided an electronic device, comprising a memory, a processor, and a computer program stored in the memory and executable on the processor, wherein the processor executes the three-dimensional model acquisition method through the computer program.

[0016] In an embodiment of the present application, a two-dimensional drawing is obtained, wherein the two-dimensional drawing includes a first pixel and a second pixel, the first pixel is a pixel that satisfies an automatic recognition condition, and the second pixel is a pixel that does not satisfy the automatic recognition condition; the second pixel is three-dimensionally labeled to obtain a second pixel carrying a three-dimensional label, wherein the three-dimensional label is used to indicate a three-dimensional pixel corresponding to the second pixel; the first pixel is automatically identified, and during the automatic identification process, the first pixel is converted into a three-dimensional pixel corresponding to the first pixel; the three-dimensional pixel corresponding to the second pixel and the three-dimensional pixel corresponding to the first pixel are integrated and processed to obtain a three-dimensional model corresponding to the two-dimensional drawing.

[0017] When it comes to converting 2D drawings to 3D models, traditional manual conversion methods are often inefficient, especially when dealing with a large number of drawings. Purely automatic conversion methods cannot guarantee that all pixels can be successfully and accurately converted into 3D pixels. Incorrect conversions will increase the number of correction steps, further reducing efficiency.

[0018] The present embodiment effectively improves the efficiency of obtaining the three-dimensional model through a combination method. First, the present embodiment distinguishes two types of pixels in the two-dimensional drawing: first pixels and second pixels. The first pixels are those elements that can be quickly converted into three-dimensional pixels directly or through some method, while the second pixels are those elements that are difficult to convert or prone to errors.

[0019] For the first pixels, since they meet certain "automatic recognition conditions", they can be converted relatively quickly and accurately. For the second pixels, this embodiment adopts a three-dimensional identification strategy. This identification not only clearly indicates the three-dimensional form that these pixels should correspond to, but also provides convenience for subsequent processing. In this way, errors and inconsistencies that may occur during the automatic conversion process are avoided, thereby reducing the need for correction.

[0020] Finally, this embodiment integrates the three-dimensional pixels corresponding to the first pixel and the second pixel. This step ensures the integrity and accuracy of the three-dimensional model, and also avoids the overall model quality degradation and increase in correction workload caused by the failure or error of some pixel conversions in the traditional method, thereby achieving the purpose of reducing the tediousness of manual conversion and avoiding the errors and correction work that may occur in automatic conversion, thereby achieving the technical effect of improving the acquisition efficiency of the three-dimensional model, and thus solving the technical problem of low acquisition efficiency of the three-dimensional model.

[0027] 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.

[0028] 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.

[0029] According to one aspect of an embodiment of the present application, a method for obtaining a three-dimensional model is provided. Optionally, as an optional implementation, the method for obtaining a three-dimensional model can be applied to, but is not limited to, Figure 1 In the environment shown, the environment may include, but is not limited to, a user device 102 and a server 112 .

[0034] Step S112 , sending the three-dimensional model to the user device 102 via the network 110 , and the user device 102 displays the three-dimensional model on the display 104 via the processor 106 , and stores the three-dimensional model in the memory 108 .

[0035] remove Figure 1 In addition to the examples shown, the terminal device may be a terminal device configured with a target client, which may include but is not limited to at least one of the following: a mobile phone (such as an Android phone, an iOS phone, etc.), a laptop, a tablet computer, a PDA, a MID (Mobile Internet Devices), a PAD, a desktop computer, a smart TV, etc. The target client may be a video client, an instant messaging client, a browser client, an education client, etc. The network may include but is not limited to: a wired network, a wireless network, wherein the wired network includes: a local area network, a metropolitan area network and a wide area network, and the wireless network includes: Bluetooth, WIFI and other networks that implement wireless communication. The server may be a single server, or a server cluster consisting of multiple servers, or a cloud server. The above is only an example, and no limitation is made to this in this embodiment.

[0036] Optionally, as an optional implementation, as Figure 2 As shown, the method for obtaining the three-dimensional model can be executed by an electronic device, which can be, for example, Figure 1 The user device or server shown in the figure comprises:

[0037] S202, obtaining a two-dimensional drawing, wherein the two-dimensional drawing includes a first pixel and a second pixel, the first pixel is a pixel that meets the automatic recognition condition, and the second pixel is a pixel that does not meet the automatic recognition condition;

[0038] S204, performing three-dimensional labeling on the second pixel to obtain the second pixel carrying the three-dimensional label, wherein the three-dimensional label is used to indicate the three-dimensional pixel corresponding to the second pixel;

[0039] S206, automatically identifying the first pixel, and in the process of automatic identification, converting the first pixel into a three-dimensional pixel corresponding to the first pixel;

[0040] S208, integrating the three-dimensional pixel corresponding to the second pixel and the three-dimensional pixel corresponding to the first pixel to obtain a three-dimensional model corresponding to the two-dimensional drawing.

[0041] In an optional embodiment, the first pixels refer to those pixels in the two-dimensional drawing that meet the system's automatic recognition conditions.

[0042] In an optional embodiment, the second pixels refer to those pixels in the two-dimensional drawing that do not meet the system's automatic recognition conditions and require additional three-dimensional identification.

[0043] In an optional embodiment, the three-dimensional identification is a special processing performed on the second pixels, which is used to clearly indicate that the three-dimensional pixels should be used when these pixels are converted into a three-dimensional model.

[0044] It should be noted that this embodiment describes a process of obtaining a three-dimensional model from a two-dimensional drawing. First, it mentions that the two-dimensional drawing contains two types of pixels: first pixels and second pixels. The first pixels are those that can be automatically recognized by the system, while the second pixels are pixels that the system cannot automatically recognize. For the second pixel, additional three-dimensional identification processing is required so that it can be correctly converted into the corresponding three-dimensional pixel in the subsequent process. Then, the system will automatically identify the first pixel and convert it into the corresponding three-dimensional pixel. Finally, the two three-dimensional pixels are integrated to obtain a complete three-dimensional model.

[0045] This embodiment can also be understood as a semi-automatic 3D model acquisition method. It combines the efficiency of automatic recognition and the accuracy of manual assistance, aiming to solve the problems of low efficiency of traditional manual conversion methods and poor accuracy of pure automatic conversion methods. In this way, the conversion efficiency from 2D drawings to 3D models can be greatly improved while ensuring the accuracy of the model.

[0046] To further illustrate, let's assume that there is a two-dimensional architectural drawing that contains multiple elements such as doors, windows, walls, and stairs. Among them, doors, windows, and walls can be automatically recognized as first elements by the system due to their regular shapes and obvious features, and directly converted into corresponding three-dimensional elements. However, stairs may not be directly recognized by the system due to their complex structure and changeable shapes, so they are regarded as second elements. For the stairs, the designer needs to manually perform three-dimensional identification and clearly specify their corresponding three-dimensional form.

[0047] Through the embodiments provided by the present application, the efficiency of acquiring three-dimensional models is significantly improved. First, a large number of first pixels are quickly processed through automatic recognition technology, reducing the time and energy of manual operation. Secondly, the second pixels are three-dimensionally marked, avoiding errors and inconsistencies that may occur during the automatic conversion process, thereby reducing the need for corrections. Finally, the three-dimensional model obtained through the integrated processing is both complete and accurate, meeting the needs of practical applications. In general, this method not only improves the efficiency of acquiring three-dimensional models, but also ensures the accuracy and completeness of the model, thereby achieving the purpose of both reducing the tediousness of manual conversion and avoiding errors and corrections that may occur in automatic conversion, thereby achieving the technical effect of improving the efficiency of acquiring three-dimensional models.

[0048] As an optional solution, performing three-dimensional labeling on the second pixel to obtain the second pixel carrying the three-dimensional label includes:

[0049] S1-1, in response to a first selection operation performed on a second pixel, displaying a three-dimensional file directory, wherein the three-dimensional file directory includes at least one three-dimensional pixel;

[0050] S1-2, in response to a second selection operation performed on a target three-dimensional pixel in at least one three-dimensional pixel, establishing an association relationship between the target three-dimensional pixel and a second pixel;

[0051] S1-3, performing three-dimensional labeling on the second pixel according to the association relationship to obtain a second pixel carrying the three-dimensional label.

[0052] In an optional embodiment, the first selection operation refers to an operation in which the user selects or clicks a second pixel in the two-dimensional drawing.

[0053] In an optional embodiment, a three-dimensional file directory: an interface or list showing available three-dimensional pixels for a user to select from to establish an association with a second pixel.

[0054] In an optional embodiment, the target three-dimensional pixel is a specific three-dimensional pixel selected by a user from a three-dimensional file directory, and is used to establish an association with the second pixel.

[0055] In an optional embodiment, the association relationship refers to a connection or a corresponding relationship established between the second pixel and the target three-dimensional pixel.

[0056] It should be noted that this embodiment describes the process of how to three-dimensionally identify the second pixel (i.e., those pixels that do not meet the automatic recognition conditions). First, when the user selects a second pixel, the system will display a file directory containing multiple three-dimensional pixels. Then, the user can select a three-dimensional pixel corresponding to the target second pixel from the directory. Once the selection is completed, the system will establish an association relationship between the selected three-dimensional pixel (target three-dimensional pixel) and the second pixel. Finally, based on this association relationship, the system will three-dimensionally identify the second pixel so that it carries the corresponding three-dimensional pixel information.

[0057] This 3D identification method not only improves the conversion efficiency from 2D drawings to 3D models, but also increases the flexibility and accuracy of the conversion process. Designers can manually specify the exact 3D form for those elements that are difficult to automatically identify according to actual needs, thereby ensuring that the final generated 3D model is more accurate and in line with the design intent.

[0058] To further illustrate, let's assume that when designing a complex mechanical part, there is a special screw hole (second element) in the drawing, and the system cannot automatically identify its corresponding 3D shape. The designer first clicks on this screw hole (performs the first selection operation), and a file directory containing various 3D models of screw holes pops up on the interface. The designer selects a 3D model that matches the screw hole in the drawing (performs the second selection operation). The system then establishes an association between this 3D model and the screw hole in the drawing, and adds a 3D mark to the screw hole on the drawing.

[0059] By marking the second pixel in three dimensions, this embodiment improves the accuracy and efficiency of converting the two-dimensional drawing to the three-dimensional model. Designers can intuitively select and specify the three-dimensional form corresponding to the second pixel, avoiding errors and mismatches that may occur during the automatic conversion process. At the same time, this semi-automatic processing method also reduces the workload of designers, allowing them to focus more on the design itself rather than the tedious model conversion work.

[0060] As an optional solution, establishing an association relationship between the target three-dimensional pixel and the second pixel includes:

[0061] The first position information of the second pixel in the two-dimensional drawing is converted into three dimensions to obtain the second position information of the target three-dimensional pixel in the three-dimensional model, wherein the first position information and the second position information are associated with each other.

[0062] In an optional embodiment, the first position information refers to the position information of the second pixel in the two-dimensional drawing, including parameters such as coordinates and angles.

[0063] In an optional embodiment, the second position information refers to the position information of the target three-dimensional pixel in the three-dimensional model, which also includes parameters such as coordinates and angles.

[0064] In an optional embodiment, the association relationship refers specifically to the corresponding relationship between the second pixel and the target three-dimensional pixel established through the conversion of orientation information.

[0065] It should be noted that this embodiment describes that when establishing an association relationship between a target three-dimensional pixel and a second pixel, a key step is to convert the position information (first orientation information) of the second pixel in the two-dimensional drawing into the corresponding position information (second orientation information) in the three-dimensional model. This conversion of orientation information ensures that the pixels in the two-dimensional drawing and the pixels in the three-dimensional model are consistent in position, thereby establishing an association relationship between them.

[0066] This conversion of orientation information is a key step in the 3D modeling process, which ensures the consistency and coherence between the 2D design and the 3D model. Through precise orientation conversion, designers can accurately restore the intent of the 2D design in a 3D environment, which is crucial for subsequent design verification, optimization, and construction.

[0067] To further illustrate, let's assume that when designing a building model, there is a second pixel representing a column in the two-dimensional drawing. In order to convert this two-dimensional column pixel into a column in the three-dimensional model, the designer needs to select the corresponding three-dimensional pixel and ensure that the position of this three-dimensional pixel in the three-dimensional model matches the position in the two-dimensional drawing. This involves converting the column position in the two-dimensional drawing (first position information) to the corresponding position in the three-dimensional model (second position information), thereby establishing an association relationship between the two pixels.

[0068] By establishing an association relationship between the target three-dimensional pixel and the second pixel, especially by accurately converting the orientation information, this embodiment ensures that the design elements in the two-dimensional drawing can be accurately presented in the three-dimensional model. This not only improves the accuracy and authenticity of the three-dimensional model, but also provides a more intuitive and comprehensive design verification environment for designers. At the same time, the establishment of this association also greatly simplifies the conversion process from two-dimensional design to three-dimensional model, and improves design efficiency.

[0069] As an optional solution, the three-dimensional pixel corresponding to the second pixel and the three-dimensional pixel corresponding to the first pixel are integrated to obtain a three-dimensional model corresponding to the two-dimensional drawing, including:

[0070] S2-1, using the three-dimensional pixel corresponding to the first pixel, establish an initial model corresponding to the two-dimensional drawing;

[0071] S2-2, inserting the target three-dimensional pixel into the initial model through the second orientation information to obtain a three-dimensional model.

[0072] In an optional embodiment, the initial model refers to a three-dimensional model constructed by only including three-dimensional pixels corresponding to the first pixel, which is the first step result of the integration process.

[0073] In an optional embodiment, the three-dimensional model refers to a complete model of the three-dimensional pixels corresponding to both the first pixel and the second pixel after the integration process is completed.

[0074] It should be noted that this embodiment describes how to integrate the three-dimensional pixels corresponding to the first pixel and the second pixel to obtain a three-dimensional model corresponding to the two-dimensional drawing. First, an initial three-dimensional model is constructed using the three-dimensional pixels corresponding to the first pixel (i.e., the pixel that meets the automatic recognition condition). Then, according to the second orientation information previously established, the target three-dimensional pixel corresponding to the second pixel (i.e., the pixel that does not meet the automatic recognition condition) is inserted into the initial model to obtain a complete three-dimensional model.

[0075] This integrated approach allows designers to adopt a phased strategy when dealing with complex 2D drawings. First, a basic model is quickly constructed through automatic recognition technology, and then those elements that are difficult to recognize automatically are manually added. This approach combines the advantages of automation and manual operation, improving efficiency while ensuring the integrity of the model.

[0076] To further illustrate, it is optional to assume that this embodiment has a two-dimensional architectural drawing, which contains automatically identifiable walls and doors and windows (first pixels), and a special decoration (second pixel). First, the system automatically identifies the walls and doors and windows, and uses their corresponding three-dimensional pixels to establish an initial three-dimensional architectural model. Then, according to the second orientation information previously set for the decoration, the three-dimensional pixel of the decoration is inserted into the initial model. Finally, this embodiment obtains a complete three-dimensional model that includes walls, doors and windows, and decorations.

[0077] By integrating the three-dimensional pixels corresponding to the first pixel and the second pixel, the present embodiment can efficiently generate an accurate and complete three-dimensional model. The rapid construction of the initial model reduces the designer's waiting time, and the subsequent manual insertion operation ensures the model's precision and personalized needs. This integrated processing method not only improves the efficiency of three-dimensional modeling, but also ensures the accuracy of the model and the flexibility of the design.

[0078] As an optional solution, after performing three-dimensional labeling on the second pixel to obtain the second pixel carrying the three-dimensional label, the method further includes:

[0079] The second pixel carrying the three-dimensional mark is put into the automatic recognition database, wherein the pixels stored in the automatic recognition database are pixels that meet the automatic recognition conditions, and the first pixel is a pixel stored in the automatic recognition database.

[0080] In an optional embodiment, automatic recognition database: a database that stores pixels that meet automatic recognition conditions, used to assist the system in automatically recognizing pixels in drawings.

[0081] It should be noted that this embodiment describes the process of adding the second pixels carrying the three-dimensional identification to the automatic recognition database after completing the three-dimensional identification of the second pixels. The automatic recognition database stores pixels that meet the automatic recognition conditions, and originally only contains the first pixels. Now, by adding the second pixels carrying the three-dimensional identification to the database, the recognition range of the database can be expanded and the automatic recognition rate of future drawings can be improved.

[0082] By adding the second pixel with a 3D mark to the automatic recognition database, the system can continuously learn and accumulate, gradually improving its ability to recognize different types of pixels. This not only improves design efficiency, but also makes the system more intelligent and adaptable. At the same time, this also means that when designers encounter similar pixels in the future, they can reduce manual operations and rely more on the system's automatic recognition function.

[0083] To further illustrate, it is optional to assume that during the design process, some specific pixels (such as a special type of valve) are often needed, but they do not meet the automatic recognition conditions. After the designer manually adds 3D labels to these pixels, the system adds these pixels with 3D labels to the automatic recognition database. In the future, when the designer uses this valve again, the system will be able to automatically recognize and convert it into the corresponding 3D pixels.

[0084] Through the embodiments provided by the present application, after the second pixel carrying the three-dimensional identification is placed in the automatic recognition database, the automatic recognition capability of the system is significantly improved. In the future, when processing two-dimensional drawings containing these pixels, the system will be able to complete the conversion from two-dimensional to three-dimensional more quickly and accurately. This not only saves the designer's time and energy, but also improves the efficiency and accuracy of three-dimensional modeling. At the same time, with the continuous expansion and improvement of the database, the intelligence level of the system will continue to improve.

[0085] As an optional solution, after obtaining the two-dimensional drawing, the method further includes:

[0086] Check whether the pixels in the two-dimensional drawing are stored in the automatic recognition database, and prompt the pixels that are not stored in the automatic recognition database to be marked.

[0087] In an optional embodiment, pixel detection refers to the system automatically checking each pixel in the two-dimensional drawing to determine whether it already exists in the automatic recognition database.

[0088] In an optional embodiment, a prompt for identification is a prompt given by the system for pixels that are not stored in the automatic recognition database, informing the user that these pixels need to be manually identified in three dimensions.

[0089] It should be noted that, in this embodiment, after obtaining a two-dimensional drawing, the system will automatically detect whether the pixels in the drawing have been stored in the automatic recognition database. For pixels not stored in the database, the system will give a prompt that needs to be marked so that the user knows which pixels need to be processed manually.

[0090] The introduction of this step greatly improves the designer's work efficiency. Through the system's automatic detection and prompts, designers can quickly locate the pixels that need to be manually processed without having to check each pixel one by one. This reduces the designer's workload and ensures the accuracy and completeness of 3D modeling.

[0091] To further illustrate, for example, a designer imports a 2D drawing containing multiple elements. After automatic detection, the system finds that there is a special mechanical part element that is not in the automatic recognition database. Therefore, the system displays a prompt mark next to the element, such as a red question mark or highlight, to remind the designer that this element needs to be manually 3D marked.

[0092] By automatically detecting the pixels in the two-dimensional drawings and giving prompts for the ones that need to be marked, this embodiment improves the efficiency of designers in processing two-dimensional drawings. Designers can quickly find and process those pixels that are not in the automatic recognition database according to the prompts of the system, thereby ensuring the smooth progress of three-dimensional modeling. This intelligent auxiliary means not only saves time, but also improves the accuracy and work efficiency of three-dimensional modeling.

[0093] As an optional solution, before the three-dimensional pixel corresponding to the second pixel and the three-dimensional pixel corresponding to the first pixel are integrated to obtain the three-dimensional model corresponding to the two-dimensional drawing, the method further includes: pre-integrating the three-dimensional pixel corresponding to the second pixel and the three-dimensional pixel corresponding to the first pixel to obtain a pre-three-dimensional model, wherein the pre-integration process includes combining the contours of the three-dimensional pixel corresponding to the second pixel and the three-dimensional pixel corresponding to the first pixel according to the position relationship;

[0094] The three-dimensional pixel corresponding to the second pixel and the three-dimensional pixel corresponding to the first pixel are integrated to obtain a three-dimensional model corresponding to the two-dimensional drawing, including: when the completeness corresponding to the three-dimensional model is greater than or equal to a preset threshold, the three-dimensional pixel corresponding to the second pixel and the three-dimensional pixel corresponding to the first pixel are integrated to obtain the three-dimensional model.

[0095] In an optional embodiment, the pre-integration process refers to the process of preliminarily combining the contours of three-dimensional pixels according to their positional relationships before formal integration.

[0096] In an optional embodiment, the pre-three-dimensional model: a preliminary three-dimensional model obtained after a pre-integration process.

[0097] In an optional embodiment, completeness: an indicator that measures the completeness and accuracy of the pre-3D model.

[0098] In an optional embodiment, a preset threshold is a set value used to determine whether the completeness of the preliminary three-dimensional model satisfies the conditions for performing formal integration processing.

[0099] It should be noted that this embodiment describes a pre-integration process before formally integrating the three-dimensional pixel corresponding to the second pixel and the three-dimensional pixel corresponding to the first pixel. The pre-integration process mainly combines the contours of the three-dimensional pixels according to the positional relationship to obtain a pre-three-dimensional model. Only when the completeness of the pre-three-dimensional model reaches or exceeds a preset threshold, the formal integration process will be performed to obtain the final three-dimensional model.

[0100] Pre-integration processing is an important intermediate step that allows designers to make a preliminary arrangement and combination of 3D pixels before formal integration. This can not only help designers check whether the relative positions and relationships between pixels are correct, but also discover and solve possible integration problems in advance. By setting a preset threshold, it can ensure that formal integration is only carried out when the pre-3D model reaches a certain degree of completeness, thereby improving the accuracy and quality of the final 3D model.

[0101] To further illustrate, it is optional to assume that the present embodiment is constructing a three-dimensional model of a complex mechanical device. Before formally combining all the parts, the present embodiment may first perform a pre-integration process to preliminarily combine the three-dimensional pixels of each part according to their positions in the device. In this way, the present embodiment can obtain a preliminary three-dimensional model, from which the general shape of the entire device can be seen. If the completeness of this preliminary three-dimensional model reaches the threshold set by the present embodiment (for example, 80%), then the present embodiment can continue with the formal integration process to obtain an accurate and complete three-dimensional model.

[0102] By introducing the mechanism of pre-integration processing and preset threshold, this embodiment improves the accuracy and efficiency of three-dimensional model construction. Pre-integration processing allows designers to perform preliminary arrangement and inspection of three-dimensional pixels before formal integration, so as to discover and solve potential problems in advance. The setting of preset thresholds ensures that formal integration processing will only be carried out when the pre-three-dimensional model reaches a certain degree of completeness, which further ensures the accuracy and quality of the final three-dimensional model. This method not only improves the efficiency of modeling, but also reduces the cost of later modification and adjustment.

[0103] As an optional solution, for ease of understanding, the above-mentioned three-dimensional model acquisition method is applied to architectural scenes, aiming to solve the problem that some pixels cannot be automatically converted during the two-dimensional to three-dimensional conversion process of CAD drawings, thereby improving modeling efficiency.

[0104] It should be noted that in the construction industry, the conversion of CAD drawings from 2D to 3D is a key link. Currently, although the program can identify some components based on pixel features and automatically convert them, there is still a problem that the pixels of some components cannot be accurately identified. This situation results in missing components in the converted 3D model, and manual modeling is required on the successfully converted model, which not only reduces modeling efficiency, but also increases the difficulty of collaborative work.

[0105] In order to solve this problem, this embodiment proposes a new method. Before conversion, this embodiment groups and identifies the pixels that cannot be intelligently converted. This identification not only contains the information of the pixels that cannot be converted, but also comes with the corresponding three-dimensional model name and storage address. This means that before the process of converting two-dimensional to three-dimensional begins, this embodiment has already prefabricated the three-dimensional models corresponding to these difficult-to-identify pixels.

[0106] In the process of converting 2D to 3D, the system first performs basic 2D to 3D model conversion. Then, by identifying the previously set manual markers, the system accurately inserts the pre-established 3D model into the identified model. This method can quickly generate a complete and accurate 3D model, greatly improving modeling efficiency and model quality.

[0107] Regarding the specific interaction method, this embodiment designs the following concise and efficient steps:

[0108] The user clicks the preset command "3D Mark" and then selects the pixel to be marked. Figure 3 As shown, the system will pop up a dialog box, prompting the user to select the corresponding 3D file directory, such as "Directory: E:\Test\Model Drawings". Once the selection is completed, the pixel identification work is also completed.

[0109] In the subsequent 3D conversion process, the user does not need to perform any additional operations. The program will automatically perform the above-mentioned insertion and integration work to generate a complete and accurate 3D model.

[0110] In this way, the present embodiment not only improves the automation of 2D to 3D conversion, but also greatly improves modeling efficiency and accuracy. At the same time, since the 3D models of the difficult-to-recognize pixels are prefabricated in advance, this also makes collaborative work easier and more efficient.

[0111] In an optional embodiment, before performing the intelligent conversion from 2D to 3D, the pixels in the 2D drawing that cannot be automatically converted are manually marked, and pixel data containing these marks is generated. This step is the basis for the subsequent conversion process and ensures that all pixels can be effectively processed.

[0112] For these specific pixels, corresponding 3D model files, i.e. preset 3D pixels, are created in advance. This step provides an accurate 3D data basis for subsequent automatic insertion operations.

[0113] During the conversion process, the system automatically detects and identifies pixels with manual markings through a preset recognition mechanism. This mechanism ensures the intelligent and automated conversion process, reducing the need for manual intervention.

[0114] The system further uses a preset mechanism to accurately identify the coordinates of the manually marked pixels and their corresponding 3D pixel file names and storage locations. The accuracy of this step is crucial for the subsequent 3D pixel insertion.

[0115] Finally, according to the identified coordinates, the system accurately inserts the preset 3D pixels into the successfully converted total model. This not only improves the overall efficiency of model conversion, but also ensures the integrity and accuracy of the 3D model.

[0116] Through the embodiments provided by the present application, two-dimensional to three-dimensional graphic insertion is performed directly according to the identification, and the accurate conversion of the two-dimensional drawing orientation information of the identification element to the three-dimensional space is realized, which significantly improves the conversion efficiency. The complex component modeling tasks are further separated from the large model and performed on the small model instead. This approach not only reduces the operating burden of the program, but also improves the flexibility and efficiency of modeling. In addition, this embodiment is also more suitable for collaborative work. Small models can be assigned to different operators, thereby realizing parallel processing of work tasks and further improving overall work efficiency.
