Description

Technical Field

[0001] This invention belongs to the field of cruise ship construction technology, and specifically relates to a system and method for inspecting the installation of cruise ship interior ceilings using AR technology, which is used for cruise ship ceiling installation, quality inspection and collaborative operation management. Background Technology

[0002] The installation and inspection of ceilings is a complex and crucial task in the construction and maintenance of cruise ships. Traditional ceiling installation relies primarily on blueprints and manual measurements, resulting in a large workload for marking and positioning, low efficiency, and a high risk of component misplacement and disorganized installation sequence, leading to increased rework time and delays in project progress. Inspection currently relies mainly on manual visual inspection, which is difficult to conduct in hidden or hard-to-reach areas, easily overlooking problems and failing to promptly identify potential safety hazards in the ceiling structure. Furthermore, cruise ship ceilings typically have complex designs and integrate multiple functional systems, such as lighting, ventilation, and fire sprinkler systems, making comprehensive and efficient installation and inspection difficult using traditional methods. With the increasing application of AR technology in the industrial field, its ability to combine virtual information with real-world scenarios offers a new approach to solving the challenges of cruise ship ceiling installation and inspection. Summary of the Invention

[0003] To address the aforementioned issues, this invention proposes an AR technology-assisted system and method for inspecting the installation of interior ceilings on cruise ships, resolving problems such as low efficiency and poor accuracy in the existing cruise ship ceiling installation and inspection processes.

[0004] The objective of this invention is achieved through the following technical solution: an AR technology-assisted inspection system for the installation of interior ceilings on cruise ships, comprising: The data processing center communicates wirelessly with the AR display device and the data acquisition device. The data processing center stores relevant data on the installation and inspection of the cruise ship's interior ceiling and transmits the corresponding data to the AR display device according to the request of the AR display device. AR display devices are used to interact with the outside world and provide wearers with virtual installation and inspection information that is combined with real-world scenarios in real time. The data acquisition equipment collects actual data from the installation site of the cruise ship's ceiling and transmits the data to the data processing center in real time for comparison and analysis.

[0005] Preferably, the data stored in the data processing center related to the installation and inspection of the cruise ship's interior ceiling includes: two-dimensional or three-dimensional model data of the cruise ship ceiling, installation process data, inspection standard data, component model images, and multimedia data.

[0006] Preferably, the two-dimensional model is derived from the two-dimensional plan layout of the ceiling at a scale of 1:1, and the three-dimensional model is a model of the ceiling and its components built at a scale of 1:1.

[0007] Preferably, AR display devices include: AR glasses, tablet computers, and AR industrial helmets.

[0008] Preferably, the data acquisition device includes a camera and sensors.

[0009] In addition to providing an AR-assisted inspection system for the installation of interior ceilings on cruise ships, this invention also provides a method for inspecting the installation of interior ceilings on cruise ships using the aforementioned system, comprising the following steps: Step 1: Import the relevant data from the cruise ship ceiling installation inspection into the data processing center; Step 2: Workers wear AR display devices at the installation site. The AR display devices are connected to the data processing center to obtain the current installation information and position the model on the actual ship. The model is then overlaid on the actual ship and displayed in the worker's field of vision in an augmented reality form. At the same time, the model selection and installation nodes are prompted in the form of animation or voice. Step 3: The construction workers install the ceiling. Step 4: After the ceiling is installed, the construction workers wear AR display devices to inspect the ceiling. The AR display devices show the corresponding inspection standards and acceptable ranges. Step 5: Inspectors record inspection results and problem information and generate a detailed report.

[0010] Preferably, in step 1, the method by which the AR display device positions the model relative to the actual ship includes: QR codes are posted at specific locations to calibrate coordinates; the actual hull structure, ribs, or LR lines on site are matched with the data to achieve virtual-real alignment.

[0011] Preferably, in step 5, the inspector takes pictures of the inspection area using a data acquisition device, and compares and analyzes the actual situation captured by the installed inspection system with standard data. If a problem is found, the AR display device prominently displays the location and type of the problem and provides corresponding solution suggestions. The system automatically records the inspection results and problem information and generates a detailed inspection report.

[0012] The beneficial effects of this invention are as follows: As can be seen from the above solution, the AR technology-assisted system and method for inspecting the installation of interior ceilings in cruise ships provided by this invention can provide workers with intuitive two-dimensional or three-dimensional installation guidance, improve installation efficiency and accuracy, and at the same time achieve comprehensive and efficient inspection of the ceiling, promptly identifying and resolving potential problems. Specific advantages are as follows: 1. Improved Installation Efficiency and Accuracy: AR technology provides intuitive installation guidance, allowing workers to clearly understand the ceiling layout and the installation locations of components such as ceiling lights, high-pressure water mist systems, smoke detectors, and speakers. This reduces positioning and measurement work during installation and minimizes errors caused by misinterpretations of 2D drawings, thus improving installation efficiency. Simultaneously, real-time installation tracking and alerts further ensure installation accuracy.

[0013] 2. Achieve comprehensive and efficient inspection: AR technology combines ceiling layout with real-world scenarios, guiding inspectors to conduct a thorough inspection of the ceiling, avoiding the drawbacks of manual visual inspection that can easily miss problems. Automatic comparison analysis and problem prompts enable inspectors to quickly identify and resolve issues, improving inspection efficiency and quality.

[0014] 3. Easy to record and manage: The system automatically records data and results during the installation and inspection process, and generates detailed reports for easy review and management later. Attached Figure Description

Detailed Implementation

[0016] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions in this embodiment will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this invention. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without creative effort are within the scope of protection of this invention.

[0017] like Figure 1 As shown, the technical solution of the present invention provides a system for inspecting the installation of interior ceilings on cruise ships using AR technology, comprising: The data processing center communicates wirelessly with the AR display device and the data acquisition device. The data processing center stores relevant data on the installation and inspection of the cruise ship's interior ceiling and transmits the corresponding data to the AR display device according to the request of the AR display device. AR display devices are used to interact with the outside world and provide wearers with virtual installation and inspection information that is combined with real-world scenarios in real time. The data acquisition equipment collects actual data from the installation site of the cruise ship's ceiling and transmits the data to the data processing center in real time for comparison and analysis.

[0018] In one embodiment of the present invention, the data processing center is used to store and process two-dimensional or three-dimensional model data of the cruise ship ceiling, installation process data, inspection standard data, component model images, multimedia data, etc., and transmit the corresponding data to the AR display device according to the request of the AR display device.

[0019] In one embodiment of the present invention, the two-dimensional model is converted from a two-dimensional plan view of the ceiling, at a scale of 1:1, and is in a format that AR can display, or a format converted to an AR-compatible format. The two-dimensional model displays the layout and height of the ceiling, and the installation positions of components such as access doors, lighting fixtures, high-pressure water mist, smoke detectors, and broadcasting systems on the ceiling, with corresponding dimension markings, centerline, and rib information. The three-dimensional model is a 1:1 scale model of the ceiling and its components, in a format that AR can display, or a format converted to an AR-compatible format. The three-dimensional model displays the layout and height of the ceiling, and the installation positions of components such as access doors, lighting fixtures, high-pressure water mist, smoke detectors, and broadcasting systems on the ceiling.

[0020] In one embodiment of the present invention, the AR display device includes AR glasses, tablet computers, AR industrial helmets and other devices with AR display functions. By wearing the AR display device, workers can view virtual installation and inspection information combined with the real scene in real time.

[0021] In one embodiment of the present invention, the data acquisition device includes a camera, sensors, etc., for collecting actual data on the installation site of the cruise ship ceiling, such as component model, component location, installation progress, etc., and transmitting this data to the data processing center for real-time comparison and analysis.

[0022] like Figure 1As shown, in addition to providing an AR-assisted inspection system for the installation of interior ceilings on cruise ships, the present invention also provides a method for inspecting the installation of interior ceilings on cruise ships using the above system, comprising the following steps: Step 1: Import the relevant data from the cruise ship ceiling installation inspection into the data processing center; Step 2: Workers wear AR display devices at the installation site. These devices connect to a data processing center to obtain current installation information and position the model relative to the actual ship, overlaying it onto the worker's field of vision in an augmented reality format. Simultaneously, animation or voice prompts are used to guide model selection and installation milestones. Positioning methods include: (1) Post QR codes at specific locations to quickly calibrate coordinates.

[0023] (2) Match the actual ship structure, ribs or LR lines on site with the data of the two-dimensional or three-dimensional model to achieve virtual-real alignment.

[0024] Step 3: Construction workers install the ceiling. Before installation, the 2D or 3D model data of the cruise ship ceiling, along with detailed installation steps, component model images, and multimedia data, are imported into the data processing center. Workers wear AR display devices at the installation site. These devices connect to the data processing center to acquire 2D or 3D model information of the current installation location and overlay it onto the worker's field of vision in augmented reality. For example, when installing a section of the ceiling, the AR display device accurately shows the ceiling's height, layout, and the positions of components such as lights, high-pressure water mist, smoke detectors, and speakers within the real-world scene. It also provides animation or voice prompts for model selection and installation milestones. The system can also automatically adjust the AR display content based on the on-site installation progress data collected by the data acquisition equipment, guiding workers to the next installation step.

[0025] Step 4: After the ceiling installation is complete, construction workers wear AR display devices to inspect the ceiling. The AR display devices show the corresponding inspection standards and acceptable ranges. During the inspection phase, the AR display devices also acquire 2D or 3D model data of the ceiling and inspection standard data. Workers wearing AR display devices inspect the ceiling, and the AR display devices show the ceiling height, layout, and the positions of components such as lights, high-pressure water mist, smoke detectors, and speakers in a real-world scene, displaying the corresponding inspection standards and acceptable ranges. For example, for the inspection of ceiling lighting fixtures, the AR display devices will show the correct installation position and model of the lights. Inspectors use data acquisition devices (such as cameras) to photograph the inspection area. The system compares and analyzes the actual situation captured with the standard data. If problems are found, the AR display devices will prominently display the problem location and type, such as incorrect light fixture model or installation deviation, and provide corresponding solution suggestions. At the same time, the system automatically records the inspection results and problem information, generating a detailed inspection report.

[0026] Step 5: Inspectors take pictures of the inspection area using data acquisition equipment. The actual situation captured by the inspection system is compared and analyzed with standard data. If a problem is found, the problem and its type are prominently displayed on the AR display device, along with corresponding solution suggestions. The system automatically records the inspection results and problem information, and generates a detailed inspection report.

[0027] The following example illustrates in detail the method for inspecting the installation of the interior ceiling of a cruise ship provided in this embodiment of the invention: The two-dimensional ceiling layout diagram is as follows Figure 2 As shown, the diagram is converted into a 2D format that can be imported into AR, or a 3D model is created based on the layout and then converted into a 3D format that can be imported into AR. The virtual 2D ceiling layout or 3D model is positioned on the actual ship. When a person wears an AR display device, they can see the virtual ceiling layout. The 2D or 3D ceiling layout should have different layers for control, allowing for the display of different types of virtual icons or models as needed. For example, lighting fixtures can be on one layer; if only the lighting fixtures are visible, only the lighting fixture layer can be displayed. The equipment on the ceiling can display attributes and installation node information for easy worker access, directly displayed virtually in the AR device. Before ceiling installation, the pipes, ducts, cables, insulation, and internal wall panels on the ceiling must be installed. The on-site construction scenario is as follows: Figure 3 As shown in the image, the on-site construction scene appears as follows after virtual display. Figure 4 As shown.

[0028] After the on-site ceiling is installed, such as Figure 5As shown, there may be errors. Displaying a virtual ceiling layout allows workers to quickly check if the ceiling installation is correct, such as... Figure 6 As shown. Additionally, the AR device compares data captured by the camera with previously stored information to use artificial intelligence to check for incorrect installation or missing installations, and then marks these locations to alert inspectors. Figure 7 As shown, after confirmation, a report can be generated, such as... Figure 8 As shown.

[0029] The above are preferred embodiments of the present invention. It should be noted that, for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
