Description

Technical Field

[0001] The present invention relates to the technical field of ship design, and in particular, to a method, system, medium and terminal for generating annotations of ship three-dimensional deliverables. Background Art

[0002] In the field of modern shipbuilding, with the continuous development of digital technology, three-dimensional deliverables have become the core basis for guiding on-site workers in production activities. Compared with traditional two-dimensional drawings, three-dimensional deliverables show significant advantages in many aspects. First, in terms of data acquisition, three-dimensional deliverables can directly extract information from digital models, avoiding the interpretation errors and information omissions that may occur in two-dimensional drawings, enabling on-site workers to obtain the required design data and production instructions more quickly and accurately. Second, in terms of information understanding, three-dimensional deliverables display the geometric shapes, spatial relationships, and assembly sequences of ship structures and components through intuitive three-dimensional views, greatly reducing the difficulty of understanding and improving work efficiency. Especially in production links with complex structures and high-precision requirements, the advantages of three-dimensional deliverables are more obvious.

[0003] However, the wide application of three-dimensional deliverables has also brought new challenges. To ensure that three-dimensional deliverables can effectively guide production, it is necessary to organically integrate necessary production information such as geometric models, model attributes, and annotations. Geometric models provide the physical shape and structural information of the ship, model attributes contain key information such as materials, processing requirements, tolerances, etc., and annotations are supplements and explanations for this information, used to clarify specific contents such as dimensions, positions, and operation requirements. Annotations play a crucial role in three-dimensional deliverables, but their complexity cannot be ignored. There are many types of annotations, including dimension annotations, text annotations, symbol annotations, etc., and each type has multiple variable attributes, such as the orientation of the annotation, font size, font type, arrangement method, color, line type, etc. The diversity and variability of these attributes make the generation and management of annotations extremely complex. A slight oversight may lead to annotation errors or inconsistencies with actual requirements, thereby affecting production efficiency and product quality. Summary of the Invention

[0044] Embodiment 1

[0045] This embodiment provides a method for generating annotations of a ship's three-dimensional deliverable. Refer to Figure 1, the method includes the following steps:

[0046] S100: Collect historical annotation data of the ship model;

[0047] Specifically, the sources of historical annotation data include 3D design software, external databases, dedicated annotation files, cloud platforms, or data management systems, etc. During the ship design process, designers use professional 3D design software, such as CAD software, to create a ship model and add annotation information to the ship model. The historical annotation data in the 3D design software is stored in the 3D model file. The historical annotation data includes geometric information data, attribute information data, and association information data. The geometric information data includes the starting and ending coordinates of the dimension line, the coordinates of the text bounding box, etc. The attribute information data includes font size, color, alignment method, etc. The association information data includes the part ID associated with the annotation, view information, etc. In some complex ship design projects, the historical annotation data may be stored in an external database for easy management and sharing. The external database can be a relational database or a non-relational database. The historical annotation data in the external database includes detailed information data, association relationship data, and historical record data. The detailed information data includes dimension values, text content, font attributes, etc. The association relationship data includes associated part ID, view information, etc. The historical record data includes modification time, modifier, modification content, etc. The historical annotation data may also be stored in dedicated annotation files that are separated from the 3D model file but remain associated with the model. With the wide application of cloud computing and data management systems, the historical annotation data may be stored in a cloud platform or a project management system. These systems provide functions such as data sharing, version control, and permission management, facilitating team collaboration and project management. The historical annotation data in the cloud platform or data management system includes detailed information data, association relationship data, and version information data. The detailed information data includes dimension values, text content, font attributes, etc. The association relationship data includes associated part ID, view information, etc. The version information data includes version number, modification history, etc.

[0048] S200: Create different types of annotation templates based on the historical annotation data;

[0049] Specifically, classify the historical annotation data according to the type, function, material description, and attributes of the historical annotation data to create different types of annotation templates. This includes creating a dimension annotation template based on the historical annotation data, creating a text annotation template based on the historical annotation data, creating a symbol annotation template based on the historical annotation data, and creating a tolerance annotation template based on the historical annotation data. Dimension annotation is used to clarify the dimension information of geometric elements and is the most common annotation type in ship design and production. The dimension annotation template includes dimension type, geometric features, text content, display attributes, and association relationships. Dimension types include linear dimension, angular dimension, radius dimension, diameter dimension, arc length dimension, etc. Geometric features include the starting and ending coordinates of the dimension line, the starting and ending coordinates of the extension line, the coordinates of the annotation frame, the rotation angle, and additional geometric elements, such as the arc line for angular annotation, the center of the circle for radius annotation, etc. Text content includes dimension values, such as 100mm, 90°; text position, such as above or below the dimension line; text alignment, such as centered alignment, left alignment; font size, font type, font color, font weight, etc. Display attributes include dimension line style, such as solid line, dashed line; dimension line color; leader style, such as whether there is a leader, leader length, and angle, etc. Association relationships include associated part ID, associated view, and dynamic association, such as updating with the movement or hiding of the part. The text annotation in the text annotation template is used to provide additional explanatory information, such as material type, processing requirements, welding symbols, etc. The text annotation template includes text content, text attributes, leader information, and association relationships, etc. The symbol annotation in the symbol annotation template is used to represent specific engineering symbols, such as welding symbols, surface treatment symbols, etc. The symbol annotation template includes symbol type, symbol position, symbol attributes, and association relationships, etc. The tolerance annotation in the tolerance annotation template is used to clarify the allowable deviation range of the dimension. The tolerance annotation template includes dimension value, tolerance range, text content, text attributes, and association relationships, etc.

[0050] S300: Obtain actual annotation data from the actual ship model;

[0051] In the actual ship design and production process, it is necessary to extract actual annotation data from the ship model, and the actual annotation data is used to guide on-site production. The actual annotation data includes self-annotation data and associated annotation data. The self-annotation data includes, but is not limited to, the type of annotation, the specific content of the annotation, the geometric information of the annotation, and the style information of the annotation. The type of annotation includes dimension annotation, text annotation, etc.; the specific content of the annotation includes dimension values, text descriptions, etc.; the geometric information of the annotation includes position coordinates, rotation angles, etc.; the style information of the annotation includes font size, color, line type, etc. Determine the annotation type, annotation position, annotation arrangement, and annotation font according to the self-annotation data, including: judging the annotation type of the self-annotation data and refining the self-annotation data based on the annotation type. Among them, the annotation type is mainly divided into two major categories: dimension annotation type and text annotation type, and also includes symbol annotation type and tolerance annotation type. The dimension annotation type needs to determine the dimension category, specifically including distance, length, angle, radius, etc., and determine additional content based on the dimension category. For example, an angle annotation needs to add an arc line, and a radius annotation requires the center position. The text annotation type is divided into pure text type and leader annotation type. If it is the leader annotation type, the coordinates of the leader anchor point need to be determined. Determine the annotation position according to the plane where the annotation is located, the center point or starting point coordinates of the annotation frame, and the rotation angle of the annotation relative to its plane. Determine the annotation arrangement according to information such as the anchor point type of the text, character spacing, and paragraph spacing. Determine the annotation font according to information such as font size, font type, font color, and font weight.

[0052] Establish an association relationship between the associated annotation data and the parts and views in the actual ship model, and realize dynamically controlling the display state of the associated annotation data according to the display state of the parts and realizing batch processing of the associated annotation data under the same view. For example, when hiding or deleting a certain view, the associated annotation data associated with that view can be grouped and hidden or deleted, so as to maintain the consistency of the associated annotation data and the views of the actual ship model.

[0053] S400: Call the corresponding annotation template according to the type of the actual annotation data, and modify the existing annotation data in the annotation template according to the actual annotation data to obtain the deliverable annotation data;

[0054] Specifically, call the corresponding annotation template according to the type of actual annotation data. For example, call the dimension annotation template, text annotation template, symbol annotation template, and tolerance annotation template according to the dimension annotation type, text annotation type, symbol annotation type, and tolerance annotation type of the actual annotation data respectively. Then, modify the corresponding historical annotation data of the corresponding annotation template according to the actual annotation data, such as dimension values, text content, and font size, etc., and dynamically adjust the historical annotation data of the annotation template to meet the actual annotation requirements. For example, modify the font size, color, or annotation position, etc. The modified historical annotation data is stored as the deliverable annotation data in the deliverable annotation file.

[0055] S500: Output the deliverable annotation data.

[0056] Specifically, the display program reads the deliverable annotation data from the deliverable annotation file and displays the deliverable annotation data in the ship model. The output form of the deliverable annotation data is diversified to meet the needs of different users and application scenarios. The deliverable annotation data can be directly displayed in the 3D view, enabling users to intuitively view the annotation information in the 3D environment. It can also be output in the form of an annotation file or a data format integrated with the production system.

[0057] The annotation generation method for the ship 3D deliverable in this embodiment can create different types of annotation templates, and the annotation templates support dynamic parameter adjustment. It can flexibly modify the parameters in the template according to the actual annotation data to adapt to different design and production requirements. It significantly improves the generation efficiency, accuracy, and consistency of annotations, and optimizes the collaborative work in ship design, production, inspection, and other links. This method not only enhances the intuitiveness of information understanding but also improves production efficiency and quality through integration with the production system, reduces error rates and rework costs, and has significant economic benefits and application value.
