Description

Technical Field

[0001] This invention relates to a method for automatically annotating the installation and positioning of ship outfitting supports in a three-dimensional model, which falls under the management technology field of ship digital design and manufacturing technology. Background Technology

[0002] With the rapid development of modern industrial technology, digitalization, intelligentization, and informatization have become important driving forces for the transformation and upgrading of the shipbuilding industry. Currently, commonly used ship design software includes AutoCAD, CATIA, ShipConstructor, and AVEVA Marine, among which AVEVA Marine is widely used in ship and marine engineering design. AVEVA Marine has strong integration capabilities, realizing cross-disciplinary functional integration of hull, outfitting, engineering, and design, providing shipbuilding companies with integrated solutions. It offers powerful 3D modeling tools, enabling designers to create detailed ship models, supporting multiple data formats and interfaces for easy integration with other software systems. Furthermore, it adopts a modular design, allowing users to select and configure different functional modules as needed to meet the requirements of different projects. Therefore, ship design is gradually transforming from two-dimensional drawings to three-dimensional drawings.

[0003] By introducing 3D visualization technology, engineers can perform complex designs and simulated tests in a virtual environment, thereby identifying and resolving potential problems in advance. While 3D visualization drawings are gradually being used in some shipyards, most are still in the exploratory stage of application. As the use of 3D visualization drawings deepens, users not only demand powerful functions but also simple operation, gradually shifting from manual 3D drawing generation to automatic generation. Ship outfitting supports play multiple crucial roles in shipbuilding, providing rigid support for pipes, cables, ventilation systems, machinery, and hull panels, ensuring their stable installation. However, as a core component of outfitting engineering, ship outfitting supports are numerous, and manually labeling all of them would be an enormous workload. Production personnel often lack drafting experience and skills, making accurate measurement difficult, especially under mobile touchscreen conditions.

[0004] Therefore, there is an urgent need for a method to automatically mark the installation and positioning of ship outfitting supports in a 3D model, which can quickly find the installation and positioning marking points of the outfitting supports and mark them in the 3D model to solve the problems mentioned in the background art. Summary of the Invention

[0005] The summary section of this application is intended to provide a brief overview of the concepts, which will be described in detail in the detailed description section below. This summary section is not intended to identify key or essential features of the claimed technical solutions, nor is it intended to limit the scope of the claimed technical solutions.

[0006] To address the problems and shortcomings of existing technologies, this invention aims to provide a method for automatically annotating the installation and positioning of ship outfitting supports in a 3D model. The method involves extracting the ship's 3D model and its attribute information files from a ship design platform and storing them on a server. On the client side, any target component within the support structure requiring positioning and annotation is selected and sent to the server. The attribute information data of the target component is retrieved and returned to the client. Based on this attribute information data, all installation and positioning annotation points for the target component are located and annotated. This invention can replace manual drawing production, significantly reducing the workload. Furthermore, since the positioning coordinates are extracted from the ship design platform, positioning and annotation errors are eliminated. This solves the problems mentioned in the background section.

[0007] To achieve the above objectives, the present invention provides the following technical solution:

[0008] As a first aspect of this application, the present invention discloses a method for automatically annotating the installation and positioning of ship outfitting supports in a three-dimensional model, comprising the following steps:

[0009] Step 1: Extract the ship's 3D model and model attribute information files from the AM software, and import the extracted ship's 3D model and model attribute information files into the 3D platform.

[0010] Step 2: In the 3D platform, parse the ship's 3D model and model attribute information file, establish the association relationship between model storage path, attributes, and design tree hierarchy, and store it on the server;

[0011] Step 3: On the client side, select any component within the target bracket to be positioned and installed as the target component and send it to the server. On the server side, retrieve the attribute information data of all components within the target bracket to which the target component belongs and return it to the client.

[0012] Step 4: The client receives the attribute information data of all components within the target bracket and locates the installation positioning mark point of the target bracket;

[0013] Step 5: Mark the installation positioning points in the three-dimensional model of the ship.

[0014] Preferably, in step 2, the ship's 3D model and model attribute information file are parsed in the 3D platform, and the association between model storage path, attributes, and design tree hierarchy is established based on the name.

[0015] Preferably, in step 3, the client sends the unique name of the target component to the server, and the server searches for the attribute information data of all components within the target bracket to which the target component belongs based on the name. The attribute information data includes the end coordinates, component type, and other data of all profiles within the target component.

[0016] Preferably, in step 4, it is necessary to first determine whether there is a pad based on the component type in the attribute information data; if there is a pad, the end connected to the pad is the installation positioning mark point, and then determine which profile end the pad is connected to according to the hierarchical relationship of the design tree; if there is no pad, both ends of the profile may be installation positioning mark points.

[0017] Preferably, step 4, which involves locating the installation positioning point of the target bracket, further includes the following steps:

[0018] Step 4.1: On the client side, based on the returned data, traverse all profiles within the target bracket that contain coordinates at both ends, remove profiles whose ends do not contact the external structure of the target bracket, and mark the coordinates of the ends of the profiles that contact the external structure of the target bracket.

[0019] Step 4.2: Group all remaining profiles after rejection into multiple collinear groups;

[0020] Step 4.3: Identify the collinear groups that are parallel to the coordinate axes of the 3D model or contain the most profiles as the target collinear groups;

[0021] Step 4.4: Determine the target profile in the collinear group. If the line where the target profile is located is parallel to the coordinate axis of the three-dimensional model, then the coordinates of the outermost profile at any end of the collinear group that contacts the outer structure of the support are the installation positioning marks.

[0022] Preferably, in step 4.1, the method for determining the coordinates of the contact end between the profile and the target support external structure is as follows: if the server only returns the coordinates of one end, then this point is the coordinate of the contact end; if the server returns the coordinates of both ends of the profile, take the coordinates of the two ends of the profile as the starting point, draw a ray from one end to the other end, calculate the distance length from the starting point of the ray to the first other professional model that intersects the ray, and select the end point whose distance length is less than 30 mm. This end point can be marked as the end point of contact with other structures.

[0023] Preferably, the end coordinates used for collinear grouping are the coordinates marked in step 4.1 and the end coordinates of the profile connecting the pad. In step 4.2, the profiles corresponding to the end coordinates of the profiles located on the same line are grouped into the same collinear group lineArr. The vector directions from the second and subsequent endpoints in the collinear group lineArr to the first endpoint are the same or opposite.

[0024] As a second aspect of this application, the present invention also discloses an electronic device, comprising:

[0025] At least one processor, and a memory communicatively connected to said at least one processor;

[0026] The memory stores instructions that can be executed by the at least one processor, which, when executed by the at least one processor, enables the at least one processor to perform the steps of the above-described method for automatically annotating the installation and positioning of ship outfitting supports in a three-dimensional model.

[0027] As a third aspect of this application, the present invention also discloses a computer storage medium storing a computer program, characterized in that, when the computer program is executed by a processor, it implements the steps of the above-described method for automatically marking the installation and positioning of ship outfitting supports in a three-dimensional model.

[0028] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0029] This invention provides a method for automatically annotating the installation and positioning of ship outfitting supports in a 3D model. The method includes extracting the ship's 3D model and model attribute information files from AM software, and importing the extracted 3D model and model attribute information files into a 3D platform. The 3D platform parses the ship's 3D model and model attribute information files, establishes the association relationship between model storage paths, attributes, and design tree levels, and stores it on a server. On the client side, any component within the target support to be installed is selected as the target component and sent to the server. The server retrieves the attribute information data of all components within the target support to which the target component belongs and returns it to the client. The client receives the attribute information data of all components within the target support, finds the installation and positioning annotation points of the target support, and finally annotates the installation and positioning annotation points in the ship's 3D model. This invention can automatically annotate the installation and positioning of ship outfitting supports, replacing manual drawing and greatly reducing the workload. It quantifies the annotation data of 3D drawings, expanding the usability of design data. Furthermore, the 3D annotation effect is more intuitive, easier to read and understand, and avoids positioning and annotation errors. Attached Figure Description

[0037] Example

[0038] This invention discloses a method for automatically marking the installation and positioning of ship outfitting supports in a three-dimensional model. The following will describe this disclosure in detail with reference to the accompanying drawings and embodiments. (Refer to...) Figure 1 As shown, the present invention mainly includes the following steps:

[0039] Step 1: Extract the ship's 3D model and model attribute information files from the AM software, and import the extracted ship's 3D model and model attribute information files into the 3D platform.

[0040] Step 2: In the 3D platform, parse the ship's 3D model and model attribute information file, establish the association between model storage path, attributes, and design tree hierarchy, and store them on the server;

[0041] Step 3: On the client side, select any component within the target bracket to be positioned and installed as the target component and send it to the server. On the server side, retrieve the attribute information data of all components within the target bracket to which the target component belongs and return it to the client.

[0042] Step 4: The client receives the attribute information data of all components within the target bracket and locates the installation positioning mark points of the target bracket.

[0043] Step 5: Mark the installation positioning points in the ship's 3D model.

[0044] AM (Advanced Marine Engineering) is a dedicated design software for ships and marine engineering, providing a complete solution from conceptual design to production and construction. It supports rapid 3D modeling of hull structures, especially in the conceptual and contract design phases, quickly generating mathematical hull models and performing fundamental calculations such as weight, stability, and cargo capacity. AVEVA Marine supports end-to-end data transfer from conceptual design to production design, reducing the risk of design iterations. It also supports multi-site collaboration suitable for large and complex projects, offering flexible configuration options to adapt to different design processes and improving overall efficiency through digital tools.

[0045] In this embodiment of the invention, the ship's 3D model file and model attribute information file are first exported from the AM software. The extracted 3D model file and model attribute information file are then imported into a 3D platform, where they are parsed. The ship's 3D model file is a core resource for the digital design and construction of ships, mainly containing the 3D geometric data, assembly relationships, and manufacturing information of outfitting components (such as pipe flanges, bollards, equipment supports, etc.). The ship's 3D model file is represented as an RVM format model file, which is a proprietary file used in AM software to encapsulate the 3D model.

[0046] The model attribute information file includes the design tree and element attributes of the 3D model. The design tree, also known as the model tree or structure tree, visually displays the assembly relationships and logical hierarchy of various components in the 3D model in a tree-like hierarchical structure. The visibility of sub-components is controlled by selecting nodes in the structure tree. The RVM format model file is parsed and converted in the 3D platform to obtain data including the face point set, triangulation index, and design parameter points of the 3D model. Design parameter points include, for example, the center point of a pipe fitting, the endpoint coordinates of a profile, and the center point of the outermost circular end face of a flange. Then, the model storage path, attributes, and design tree hierarchy are established in the 3D platform based on names. Finally, the exported ship 3D model file, model attribute information file, and the established relationships are stored on the server.

[0047] We use the Three.js 3D engine on the client side to load and display the 3D model. On the client side, any component within the support structure that needs to be positioned and annotated is selected as the target component. Support structures are generally composed of multiple profiles and base plates. Profiles are one of the basic materials constituting outfitting components and are widely used in supports, frames, and supporting structures. The client sends the unique name of the target component to the server. On the server side, based on the name, it retrieves the type, name, and end coordinates of all components within the support structure containing the target component—that is, the component's attribute information—and then returns the data to the client.

[0048] For all components within the target bracket belonging to the target component, the first step is to determine whether it is a profile or a backing plate based on its type. If it is determined to be a profile and there is no backing plate at the end, then both ends of the profile could be installation positioning points, and the coordinate data of both ends of the profile need to be returned to the client. However, if it is determined to be a profile and there is a backing plate at the end, according to design principles, the end connected to the backing plate can necessarily be used as an installation positioning point, so the coordinate value of the other end point is removed from the returned value. Finally, the type, name, and end installation positioning coordinates of all components within the bracket containing the target component are returned to the client. The client receives the attribute information data of the target component and finds the installation positioning mark point of the profile within the target component.

[0049] Locating the installation positioning points of the target bracket also includes the following steps:

[0050] Step 4.1: On the client side, based on the returned data, traverse all profiles within the target bracket that contain coordinates at both ends, remove profiles whose ends do not contact the external structure of the target bracket, and mark the coordinates of the ends of the profiles that contact the external structure of the target bracket.

[0051] Step 4.2: Group all remaining profiles after rejection into multiple collinear groups;

[0052] Step 4.3: Identify the collinear groups that are parallel to the coordinate axes of the 3D model or contain the most profiles as the target collinear groups;

[0053] Step 4.4: Determine the target profile in the collinear group. If the line where the target profile is located is parallel to the coordinate axis of the three-dimensional model, then the coordinates of the outermost profile at any end of the collinear group that contacts the outer structure of the support are the installation positioning marks.

[0054] Specifically, in step 4.1, the method for determining the coordinates of the contact end between the profile and the external structure of the support is as follows: if the server only returns the coordinates of one end, then this point is the coordinate of the contact end. If the server returns the coordinates of both ends of the profile, rays are drawn from one end to the other, starting from the coordinates of both ends of the profile. The distance *length* from the ray's starting point to the first other professional model that intersects the ray is calculated. The endpoint with a distance *length* less than 30 mm is selected and marked as the endpoint of the contact end with other structures. For all profiles in the target component, all profiles are grouped collinearly within the client. Profiles with end coordinates on the same line are grouped into the same collinear group *lineArr*. The method for determining collinearity is that the end coordinates used for collinearity determination are the coordinates marked in step 4.1 and the end coordinates of the profile at the connecting pad end. The vector directions from the second and subsequent endpoints in the collinear group *lineArr* to the first endpoint are the same or opposite.

[0055] Next, identify the collinear groups parallel to the coordinate axes or containing the largest number of profiles as the target collinear groups. Prioritize identifying the collinear group lineArr parallel to the coordinate axes as the target collinear group; if none exists, then identify the collinear group lineArr containing the largest number of profiles. After determining the collinear groups to be marked, calculate the spacing to identify the profiles furthest apart within the collinear group as the outermost profile, i.e., the target marked profile. Determine if the line containing the target profile is parallel to the coordinate axes. If the line containing the target profile is parallel to the coordinate axes, simply mark the positioning at the point on the connecting plate end or the endpoint marked in step 4.1. If it is not parallel, the positioning at both ends of the profile needs to be marked. In other words, if the length direction of the profile to be marked is not parallel to the coordinate axes, markings need to be made at both ends of the profile. Finally, mark the corresponding profiles in the ship's 3D model, such as... Figure 2 As shown.
