Description

Technical Field

[0001] The present application relates to the field of bridge construction, and in particular to a bridge construction standard visualization method, device, equipment and medium. Background Art

[0002] The construction of safety production standardization in highway construction enterprises is an important means to effectively prevent accidents. In-depth construction of safety production standardization can further standardize the safety behavior of practitioners, improve the level of mechanization and informatization, promote the investigation and treatment of various hidden dangers on site, promote the construction of a long-term mechanism for safety production, effectively prevent and resolutely curb accidents, and promote the continuous and stable improvement of the national safety production situation.

[0003] At present, the display of bridge construction standards mostly exists in the traditional text form. Although this form is detailed, it is relatively boring and cannot intuitively display the various links and details in the bridge construction process, which affects the construction personnel's understanding and application of the standards and is not convenient for construction personnel to quickly understand and master them. Therefore, how to improve the intuitive display of bridge construction standards has become a problem that needs to be solved urgently. Summary of the invention

[0004] In order to improve the intuitive display of bridge construction standards, the present application provides a bridge construction standard visualization method, device, equipment and medium.

[0005] In the first aspect, the present application provides a bridge construction standard visualization method, which adopts the following technical solution: A bridge construction standard visualization method, comprising: Obtain the name of the current construction project, and load the plane construction model corresponding to the current construction project; displaying the planar construction model; When a standard query operation corresponding to the plane construction model is received, determining a target construction sub-area corresponding to the standard query operation; Acquire a target BIM sub-model corresponding to the target construction sub-area and a construction standard corresponding to the target BIM sub-model; According to the display rules, the target BIM sub-model and the construction standard corresponding to the target BIM sub-model are displayed.

[0006] By adopting the above technical solution, the name of the current construction project is obtained and the corresponding plane construction model is loaded, so that the intuitive display of the construction project is realized, so that each construction worker can understand the project structure, layout and details more intuitively. After receiving the standard query operation on the plane construction model, the target construction sub-area is automatically determined, and the BIM sub-model and its construction standards corresponding to the area are obtained. According to the preset display rules, the BIM sub-model and its construction standards are displayed to the construction personnel together, which further enhances the accuracy and pertinence of construction management, helps to reduce construction errors caused by misunderstandings, and improves construction quality and efficiency. At the same time, the BIM sub-model is automatically associated with the construction standard and displayed to relevant personnel in real time, which improves the intuitive display of bridge construction standards and greatly promotes the compliance and implementation of construction standards. It can not only improve the compliance of construction projects, reduce legal risks and economic losses caused by illegal operations, but also enhance the safety and reliability of projects.

[0007] In a possible implementation, before obtaining the name of the current construction project, the method further includes: Obtaining the construction drawings corresponding to the current construction project, and establishing a plane construction model and an initial BIM model of the construction drawings; Obtaining technical disclosure content corresponding to the construction drawing, wherein the technical disclosure content includes multiple construction requirements; Based on the technical disclosure content, determine the construction standard corresponding to the construction drawing and the display rule corresponding to the construction standard; The construction standard is marked at the position corresponding to the initial BIM model, and based on the construction drawing, the marked BIM model is divided into multiple BIM sub-models to obtain the BIM model and multiple BIM sub-models corresponding to the current construction project.

[0008] By adopting the above technical solution, by obtaining the construction drawings of the current construction project and establishing the plane construction model and the initial BIM model based on them, it is ensured that all key information of the construction project is accurately captured and digitized, which helps to reduce construction problems caused by missing or incorrect information. Then, by obtaining the technical disclosure content corresponding to the construction drawings, multiple construction requirements in the construction process are clarified, providing a specific basis for the formulation of construction standards, which not only improves the transparency of the project, but also ensures that the construction team can have a clear understanding of the project requirements before construction, thereby improving the accuracy and comprehensiveness of construction preparation work. Based on the construction standards determined by the technical disclosure content, by marking them at the corresponding positions of the initial BIM model, a direct association between the construction standards and the project entities is achieved. This association not only makes the construction standards more specific and operational, but also provides intuitive guidance for standard compliance during the construction process. In addition, by dividing the annotated BIM model into multiple BIM sub-models, the granularity of construction management is further refined, so that each construction sub-area has its corresponding BIM sub-model and construction standard, which is convenient for the construction team to carry out targeted management and operation.

[0009] In a possible implementation, establishing the planar construction model of the construction drawing includes: Performing vector processing on the construction drawing to obtain a digital format corresponding to the construction drawing; Determine a warning sign corresponding to the current construction project; Based on the digital format and the warning signs, a plane construction model of the construction drawing is established.

[0010] By adopting the above technical solution, the traditional paper or bitmap format drawings are converted into high-precision digital formats by vectorizing the construction drawings, which not only retains the original information of the drawings, but also greatly improves the accuracy and editability of the data. In the process of establishing a plane construction model, the warning signs corresponding to the current construction project are determined and integrated into the model. These warning signs may include dangerous areas, prohibited areas, safe exits, etc. Their clear markings in the model help remind construction workers to pay attention to construction safety and avoid potential dangers. Integrating warning signs into the plane construction model not only enhances the safety and warning of the model, but also helps to improve the safety awareness of construction workers. During the construction process, construction workers can refer to the warning signs in the model at any time to ensure that their behavior complies with safety regulations and reduce the occurrence of safety accidents.

[0011] In a possible implementation, based on the technical disclosure content, determining the construction standard corresponding to the construction drawing and the display rule corresponding to the construction standard includes: Based on the technical disclosure content, obtain the construction sub-standard corresponding to each construction requirement to obtain the construction standard corresponding to the construction drawing; Determine the importance of each construction sub-criteria; Sorting the construction sub-standards in descending order of importance to obtain a sub-standard sequence; Obtain a standard video corresponding to each construction sub-standard, where the standard video is used to demonstrate the consequences of not performing construction in accordance with the construction sub-standard; Based on the sub-standard sequence and the annotated video corresponding to each construction sub-standard, a display rule corresponding to the construction standard is determined.

[0012] By adopting the above technical solution and through the technical disclosure content, the construction sub-standards corresponding to each construction requirement were obtained, so as to construct a complete construction standard system for construction drawings. At the same time, by determining the importance of each construction sub-standard and ranking them, the key construction links are further highlighted, providing clear priority guidance for the construction team. At the same time, standard videos are introduced as an auxiliary display method for construction standards. Each construction sub-standard corresponds to a standard video, which intuitively shows the serious consequences of not following the construction sub-standards. This visual display method is more impactful and persuasive than traditional text descriptions, and can more effectively improve the safety awareness and quality awareness of construction workers. Through the display of standard videos, construction workers can more intuitively realize the importance of construction standards and the serious consequences of not complying with the standards, thereby enhancing their awareness and initiative to comply with construction standards.

[0013] In a possible implementation, after displaying the target BIM sub-model and the construction standard corresponding to the target BIM sub-model, the method further includes: When receiving an image acquisition instruction, acquiring a construction image of the current construction project; Identifying project lines in the construction image, and comparing the project lines with model lines corresponding to each of the BIM sub-models to obtain a comparison similarity; The BIM sub-models whose comparison similarity is greater than a similarity threshold are determined as similar BIM sub-models, and the similar BIM sub-models are displayed.

[0014] By adopting the above technical solution, by receiving image acquisition instructions and acquiring the construction image of the current construction project, the project lines in the construction image are identified and compared with the model lines in the BIM sub-model, similar BIM sub-models are determined by comparing the similarities, and these models are displayed. This enables construction personnel to determine the BIM sub-model corresponding to the actual site from the BIM model and display it when they are on the site of the construction project, which is beneficial for construction personnel to perform BIM model queries and standard queries at any construction location, thereby further improving the accuracy and pertinence of construction management.

[0015] In a possible implementation, displaying the similar BIM sub-model includes: Collect images of current construction workers; Identify the protective tools worn by the current construction worker in the personnel image, and determine whether the protective tools worn by the current construction worker meet the requirements; If the protective tools currently worn by the construction personnel meet the requirements, the construction standard corresponding to the similar BIM sub-model is obtained, and the similar BIM sub-model and the construction standard corresponding to the similar BIM sub-model are displayed; If the protective tools currently worn by the construction workers do not meet the requirements, the protective video corresponding to the similar BIM sub-model is obtained, and the similar BIM sub-model, the construction standards corresponding to the similar BIM sub-model and the protective video are displayed. The protective video is used to demonstrate the function of the protective tools corresponding to the sub-model.

[0016] By adopting the above technical solution, according to the current construction scene and the needs of construction workers, the system can automatically match and display the relevant BIM sub-models and their construction standards, so that construction workers can quickly understand and master the specific construction requirements and standards of the current work area, improving the pertinence and effectiveness of training. Through the display of BIM sub-models, construction workers can intuitively see the structure, layout and details of the construction object. At the same time, by collecting the images of the current construction workers and identifying the protective tools they wear, it is possible to judge in real time whether the protective equipment of the construction workers meets the safety requirements. When it is found that the construction workers are not wearing or wearing protective tools incorrectly, by displaying the protection video corresponding to the similar BIM sub-model, the importance and role of wearing protective tools correctly are intuitively demonstrated. This educational method is more vivid and effective than traditional oral or written guidance, and can significantly improve the safety awareness and self-protection ability of construction workers.

[0017] In the second aspect, the present application provides a bridge construction standard visualization device, which adopts the following technical solution: A bridge construction standard visualization device, comprising: A name acquisition module is used to acquire the name of the current construction project and load the plane construction model corresponding to the current construction project; A first display module, used for displaying the plane construction model; An area determination module, configured to determine a target construction sub-area corresponding to the standard query operation when receiving a standard query operation corresponding to the plane construction model; A standard module, used to obtain a target BIM sub-model corresponding to the target construction sub-area and a construction standard corresponding to the target BIM sub-model; The second display module is used to display the target BIM sub-model and the construction standard corresponding to the target BIM sub-model according to the display rules.

[0018] In a possible implementation, the bridge construction standard visualization device further includes: A drawing acquisition module is used to acquire the construction drawings corresponding to the current construction project and establish a plane construction model and an initial BIM model of the construction drawings; A content acquisition module, used to acquire the technical disclosure content corresponding to the construction drawing, wherein the technical disclosure content includes multiple construction requirements; A rule determination module, used to determine the construction standard corresponding to the construction drawing and the display rule corresponding to the construction standard based on the technical disclosure content; The marking module is used to mark the construction standard at the position corresponding to the initial BIM model, and based on the construction drawing, divide the marked BIM model into multiple BIM sub-models to obtain the BIM model and multiple BIM sub-models corresponding to the current construction project.

[0020] In a fourth aspect, the present application provides a computer-readable storage medium, which adopts the following technical solution: A computer-readable storage medium includes: a computer program that can be loaded by a processor and execute the bridge construction standard visualization method described in the first aspect.

[0021] In summary, the present application includes the following beneficial technical effects: obtaining the name of the current construction project and loading the corresponding plane construction model, realizing the intuitive display of the construction project, so that each construction worker can more intuitively understand the project structure, layout and details. After receiving the standard query operation on the plane construction model, the target construction sub-area is automatically determined, and the BIM sub-model and its construction standards corresponding to the area are obtained. According to the preset display rules, the BIM sub-model and its construction standards are displayed to the construction personnel together, further enhancing the accuracy and pertinence of construction management, helping to reduce construction errors caused by misunderstandings, and improving construction quality and efficiency. At the same time, the BIM sub-model is automatically associated with the construction standards and displayed to relevant personnel in real time, which greatly promotes the compliance and implementation of construction standards, which can not only improve the compliance of construction projects, reduce legal risks and economic losses caused by illegal operations, but also enhance the safety and reliability of projects.

DETAILED DESCRIPTION

[0023] The following is combined with Figure 1 -Attached Figure 3 This application is described in further detail.

[0024] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, 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 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 are within the scope of protection of this application.

[0025] The present application embodiment provides a bridge construction standard visualization method, such as Figure 1As shown, the method provided in the embodiment of the present application is performed by an electronic device, which can be a server or a terminal device, wherein the server can be an independent physical server, or a server cluster or distributed system composed of multiple physical servers, or a cloud server providing cloud computing services. The terminal device can be a smart phone, a tablet computer, a laptop computer, a desktop computer, etc., but is not limited thereto. The terminal device and the server can be directly or indirectly connected via wired or wireless communication, which is not limited in the embodiment of the present application. The method includes steps S101 to S105, wherein: Step S101, obtain the name of the current construction project, and load the plane construction model corresponding to the current construction project.

[0026] Among them, one project corresponds to one project name. Before the formal construction of the bridge, the project name and project drawings already exist. Specifically, the project drawings corresponding to the project can be obtained according to the name of the current construction project, and the project drawings can be vectorized. The vectorized project drawings can be identified using plane processing software to obtain the plane construction model corresponding to the project. After obtaining the name of the current construction project, the plane construction model corresponding to the current project construction can be obtained and loaded.

[0027] Step S102: display the plane construction model.

[0028] After the plane construction model corresponding to the current project construction is loaded, the plane construction model can be displayed for the convenience of construction personnel to view.

[0029] Step S103: When a standard query operation corresponding to the plane construction model is received, a target construction sub-area corresponding to the standard query operation is determined.

[0030] When the electronic device displays the plane construction model, the construction personnel can drag or zoom in the plane construction model to view the model in more detail. At the same time, when the construction personnel want to view the construction standards of the construction project, they can click on the standard query operation, and the electronic device receives the standard query operation corresponding to the plane construction model. In order to further facilitate the construction personnel to view the construction standards, the construction area on the construction drawing can be partially displayed. Specifically, the construction area can be divided into multiple construction sub-areas according to the preset division rules.

[0031] When the electronic device receives a standard query operation corresponding to the plane construction model, the construction sub-area corresponding to the received standard query operation is used as the target construction sub-area.

[0032] Step S104: Obtain a target BIM sub-model corresponding to the target construction sub-area and a construction standard corresponding to the target BIM sub-model.

[0033] Among them, use BIM software (such as Revit, ArchiCAD, Tekla Structures, etc.) to import the project drawings after vectorization, and automatically create a three-dimensional model in the BIM software to obtain the BIM model of the current construction project, and mark the corresponding construction standards in the BIM model, and divide the BIM model into multiple BIM sub-models according to the preset division rules. Among them, one BIM sub-model corresponds to at least one construction standard.

[0034] Specifically, when a standard query operation is received, a target BIM sub-model corresponding to the target construction sub-area may be obtained, and a construction standard corresponding to the target BIM sub-model may be obtained.

[0035] Step S105: Display the target BIM sub-model and the construction standard corresponding to the target BIM sub-model according to the display rules.

[0036] The display rule may be a rule for displaying the construction standards in order of importance, that is, the higher the importance of the construction standards, the earlier they are displayed. Specifically, each construction standard corresponds to an importance label, and each BIM sub-model corresponds to a display rule according to the importance label.

[0037] Further, after the display order of the BIM sub-models is obtained, the target BIM sub-model may be displayed, and at the same time, the construction standard of the target BIM sub-model may be displayed according to the display order.

[0038] The embodiment of the present application provides a bridge construction standard visualization method. The present application realizes the intuitive display of the construction project by obtaining the name of the current construction project and loading the corresponding plane construction model, so that each construction worker can more intuitively understand the project structure, layout and details. After receiving the standard query operation on the plane construction model, the target construction sub-area is automatically determined, and the BIM sub-model and its construction standard corresponding to the area are obtained. According to the preset display rules, the BIM sub-model and its construction standard are displayed to the construction personnel together, further enhancing the accuracy and pertinence of construction management, helping to reduce construction errors caused by misunderstandings, and improving construction quality and efficiency. At the same time, the BIM sub-model is automatically associated with the construction standard and displayed to relevant personnel in real time, which greatly promotes the compliance and implementation of the construction standard, which can not only improve the compliance of the construction project, reduce the legal risks and economic losses caused by illegal operations, but also enhance the safety and reliability of the project.

[0039] In a possible implementation of the embodiment of the present application, before step S101, obtaining the name of the current construction project, the method may further include: Obtain the construction drawings corresponding to the current construction project, and establish the plane construction model of the construction drawings and the initial BIM model; Obtain the technical disclosure content corresponding to the construction drawings, which includes multiple construction requirements; Based on the technical disclosure content, determine the construction standards corresponding to the construction drawings and the display rules corresponding to the construction standards; The construction standards are marked at the corresponding positions of the initial BIM model, and based on the construction drawings, the marked BIM model is divided into multiple BIM sub-models to obtain the BIM model and multiple BIM sub-models corresponding to the current construction project.

[0040] The technical disclosure content may include construction task sub-content, technical requirement sub-content, quality standard sub-content, safety precautions sub-content, etc., and one sub-content corresponds to one construction requirement. The technical disclosure content corresponding to different construction projects may be different.

[0041] Specifically, obtain the complete construction drawings and technical briefing documents of the current construction project, and create a plane construction model of the project in the BIM modeling software according to the obtained construction drawings. At the same time, based on the plane construction model, use the BIM modeling software to establish a three-dimensional BIM model to obtain the initial BIM model corresponding to the current construction project.

[0042] Furthermore, the technical briefing content is identified to obtain the construction requirements corresponding to the current construction project and the importance of each construction requirement, and the standard corresponding to each construction requirement is obtained to obtain the construction standard of the construction drawing corresponding to the current construction project. Based on the importance of the construction requirements, the standard corresponding to each construction requirement is displayed in order from the largest to the smallest importance to obtain the display rules corresponding to the construction standards. Specifically, the technical briefing content corresponding to the current construction project is input into the trained first model to obtain the construction requirements output by the first model and the importance of each construction requirement. Among them, one construction requirement corresponds to one standard, which comes from national specifications, industry standards or project-specific requirements. The first model is trained with a large number of technical briefing content samples, construction requirement samples and importance samples corresponding to each construction requirement sample.

[0043] Furthermore, on the initial BIM model, based on the obtained construction standards, the corresponding positions are marked, and the marked BIM model is divided into multiple BIM sub-models according to the preset division rules, and the corresponding construction standards and display rules are associated with each BIM sub-model to ensure that these rules can be automatically applied during display. The marking can be in the form of text, icons, color blocks, etc., to ensure that construction personnel can clearly identify them.

[0044] A possible implementation of the embodiment of the present application is to establish a planar construction model of a construction drawing, including: Vectorize the construction drawings to obtain the digital format corresponding to the construction drawings; Determine the warning signs corresponding to the current construction project; Create a flat construction model of the construction drawings based on digital format and warning signs.

[0045] When the construction drawings are paper drawings, use a high-precision scanner to scan the paper construction drawings into high-resolution image files (such as TIFF, JPEG, etc.), and use image processing software (such as Adobe Photoshop) to perform pre-processing operations such as denoising, adjusting brightness and contrast, and cropping on the scanned images to ensure that the images are clear and accurate. Among them, the construction drawings generally have areas marked with words such as "dangerous", "high voltage", and "flammable and explosive", which often involve potential safety risks.

[0046] Specifically, the lines and shapes in the construction drawing images are automatically identified and converted into vector objects using the software's automatic vectorization function. The construction drawings are identified to obtain areas that require special attention or warnings, such as dangerous areas, prohibited construction areas, areas with special construction requirements, etc. Furthermore, according to project regulations or industry standards, appropriate warning signs are selected, and the location and related information of each warning sign are recorded in the vectorized version of the construction drawings. This information can be coordinates, annotations, or specific layer markers. Among them, warning signs can appear in the form of graphics, colors, or text to remind construction personnel to pay attention to specific matters.

[0047] Furthermore, the construction drawings that have been vectorized and marked with warning signs are imported into BIM modeling software or CAD software, and different layers are created in the software to distinguish different types of construction information (such as structure, equipment, warning signs, etc.). The elements in the vector drawings are assigned to the corresponding layers according to their attributes for subsequent management and editing. According to the instructions and requirements of the construction drawings, necessary annotations, dimensioning, material descriptions and other information are added to the model.

[0048] A possible implementation of the embodiment of the present application is to determine the construction standard corresponding to the construction drawing and the display rule corresponding to the construction standard based on the technical disclosure content, including: Based on the technical briefing content, obtain the construction sub-standards corresponding to each construction requirement to obtain the construction standards corresponding to the construction drawings; Determine the importance of each construction sub-criteria; Sort the construction sub-standards in descending order of importance to obtain a sub-standard sequence; Obtain the standard video corresponding to each construction sub-standard. The standard video is used to show the consequences of not following the construction sub-standard. Based on the sub-standard sequence and the annotated video corresponding to each construction sub-standard, the display rules corresponding to the construction standard are determined.

[0049] Specifically, the technical briefing content corresponding to the current construction project is input into the trained second model to obtain the construction sub-standard corresponding to each construction requirement output by the second model, and the construction standard corresponding to the construction drawing is obtained based on each construction sub-standard. The second model is trained with a large number of technical briefing content samples, construction requirement samples, and construction sub-standard samples corresponding to each construction requirement sample.

[0050] Furthermore, the construction sub-standards are input into the trained third model to obtain the importance labels of the construction sub-standards output by the third model, and a quantitative indicator (such as weight, score, etc.) is assigned to each construction sub-standard to indicate its importance. The third model is trained with a large number of construction sub-standard samples and importance label samples.

[0051] Furthermore, according to the quantified importance, the construction sub-standards are sorted from large to small to form a sub-standard sequence. Obtain the standard video corresponding to each construction sub-standard. Among them, the standard video should intuitively show the correct construction method according to the construction sub-standard and the possible consequences of not following the construction sub-standard. Among them, before establishing the BIM model corresponding to the current construction project, collect the standard video corresponding to each construction sub-standard, and classify and organize the collected standard videos according to the construction sub-standard to ensure that each construction sub-standard has one or more corresponding video resources.

[0052] Furthermore, based on the sub-standard sequence and importance, the display rules of the construction standards are formulated. Specifically, in the BIM model or construction management software, the construction standards are displayed in the order of the sub-standard sequence to ensure that the standards with high importance are seen first. When the user selects or pays attention to a certain construction sub-standard, the corresponding standard video is automatically played or prompted, so that the user can understand the construction requirements and consequences more intuitively. In the BIM model, different colors, icons or annotations are used to mark the construction sub-standards of different importance to enhance visual distinction.

[0053] In a possible implementation of the embodiment of the present application, after displaying the target BIM sub-model and the construction standard corresponding to the target BIM sub-model in step S105, the method further includes: When receiving an image acquisition instruction, acquiring a construction image of the current construction project; Identify the project lines in the construction image and compare the project lines with the model lines corresponding to each BIM sub-model to obtain the comparison similarity; The BIM sub-models whose comparison similarity is greater than the similarity threshold are determined as similar BIM sub-models, and the similar BIM sub-models are displayed.

[0054] When the current construction project has started construction, the construction workers may not be able to obtain the specific location of the current construction location on the construction drawing due to the large amount of bridge engineering during the construction process. Therefore, in order for the construction workers to know the specific location of the current construction location on the construction drawing, the construction workers can send image acquisition instructions through electronic devices (such as tablet computers, smart phones) to collect construction images of the current construction project. After obtaining the construction image of the current construction project, the collected construction images can be pre-processed, including denoising, contrast enhancement, brightness adjustment, etc., to improve the image quality, and edge detection algorithms (such as Canny edge detectors) are used to identify edge lines in the image, which represent the contours and structural lines of the construction project.

[0055] From the identified edge lines, project lines representing key structures or features of the project are extracted according to preset rules or algorithms (such as based on shape, size, position and other features), and the BIM sub-model corresponding to the current construction project is obtained, where each BIM sub-model contains the model lines of the construction project.

[0056] Furthermore, for each BIM sub-model, the corresponding model lines are extracted, and the project lines in the construction image are compared with the model lines of each BIM sub-model. The comparison method may include calculating the geometric similarity (such as length, angle, position, etc.), shape matching, etc. of the lines, calculating the comparison similarity for each compared line, and summarizing the overall similarity between the BIM sub-model and the construction image. Furthermore, the calculated overall similarity is compared with the similarity threshold, and the BIM sub-model with a comparison similarity greater than the threshold is found as a similar BIM sub-model, and the similar BIM sub-model is displayed. When there is no BIM sub-model with a comparison similarity greater than the threshold, an error alarm is generated.

[0057] A possible implementation of the embodiment of the present application, displaying similar BIM sub-models, includes: Collect images of current construction workers; Identify the protective tools worn by the current construction worker in the personnel image, and determine whether the protective tools worn by the current construction worker meet the requirements; If the protective tools currently worn by the construction personnel meet the requirements, the construction standards corresponding to the similar BIM sub-models are obtained, and the similar BIM sub-models and the construction standards corresponding to the similar BIM sub-models are displayed; If the protective tools currently worn by the construction workers do not meet the requirements, the protection video corresponding to the similar BIM sub-model is obtained, and the similar BIM sub-model, the construction standards corresponding to the similar BIM sub-model and the protection video are displayed. The protection video is used to show the function of the protective tools corresponding to the sub-model.

[0058] Specifically, when an image acquisition instruction is received, in order to ensure the construction safety of the current construction workers, image acquisition can be performed on the current construction workers to obtain a full-body or upper-body image of the current construction workers to ensure that the protective tools they wear can be clearly seen.

[0059] Furthermore, the collected personnel images are preprocessed, such as denoising, adjusting brightness and contrast, to improve recognition accuracy. Computer vision technology (such as deep learning models) is used to identify the protective tools worn by construction workers in the image, such as safety helmets, safety belts, protective glasses, etc. According to preset standards or rules (such as color, type, wearing method, etc.), it is determined whether the protective tools worn by the current construction workers meet safety requirements. Specifically, the recognition results can be compared with the samples of compliant protective tools stored in the database to determine whether the protective tools worn by the current construction workers meet safety requirements.

[0060] If the result of the judgment is that the protective tool meets the requirements, the electronic device continues to execute the process of displaying similar BIM sub-models. The BIM sub-model most similar to the current construction scene and its corresponding construction standards are obtained from the BIM database. On the display interface, the three-dimensional view of the similar BIM sub-model and the relevant construction standard information (such as text description, diagram, etc.) are displayed at the same time.

[0061] If the result of the judgment is that the protective tools do not meet the requirements, the electronic device, in addition to displaying similar BIM sub-models and construction standards, obtains protective videos corresponding to similar BIM sub-models from the BIM database. These videos should demonstrate the importance of correctly wearing and using protective tools, as well as the specific role of protective tools in the construction scenes corresponding to the sub-models.
