[0039] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are only used to explain the present invention, rather than to limit the present invention. It should also be noted that, for ease of description, only parts related to the present invention, rather than all structures, are shown in the accompanying drawings.

[0040] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are only used to explain the present invention, rather than to limit the present invention. It should also be noted that, for ease of description, only parts related to the present invention, rather than all structures, are shown in the accompanying drawings.

[0041] Before introducing the technical solution provided by the embodiment of the present invention, an example description of the application scenario may be given first.

[0042] Before making a ship, the hull structure corresponding to the ship is usually drawn based on existing drawing software. The hull structure is composed of multiple curved surfaces. When the curved surface is imported into other software based on the 3DD file format as the background of the outfitting module, the surface accuracy can be adjusted based on the method provided in the embodiment of the present invention to achieve the effect of improving the display accuracy of the model.

[0043] Figure 1 A flowchart of a method for adjusting the display accuracy of a ship surface model provided in an embodiment of the present invention. This embodiment can be applied to any scenario where a ship structure drawn in software needs to be exported and its surface accuracy needs to be adjusted. The method can be implemented by a device for adjusting the display accuracy of a ship surface model integrated in a client or server by software and / or hardware. The hardware can be an electronic device, which can be a PC or a mobile terminal, etc.

[0044] like Figure 1 As shown, the method specifically comprises the following steps:

[0045] S110. Receive a surface precision control parameter, wherein the surface precision control parameter is used to constrain the display precision of at least one surface constituting the target ship.

[0046] Among them, the surface accuracy control parameter can be understood as a pre-set parameter used to limit the resolution in which the output surface is displayed. Optionally, when the surface accuracy control parameter is a1, it means that the output surface accuracy is compatible with a1. For a more concrete example, if the surface accuracy control parameter is 256, it means that each surface constituting the ship needs to be drawn by 256 points when it is imported; if the surface accuracy control parameter is 512, it means that each surface constituting the ship needs to be drawn by 512 points when it is exported. Generally, the higher the surface accuracy control parameter, the higher the accuracy requirement for the surface, and it is necessary to determine multiple points to draw the exported surface. The number of at least one surface can be one or more, and the specific number is related to the number of surfaces of the ship constructed during the design.

[0047] It can be understood that after receiving the surface precision control parameter, the display information corresponding to the derived target surface can be determined based on the surface precision control parameter.

[0048] It should also be noted that, in practical applications, all surfaces constituting a ship can be processed in batches, that is, the same surface precision control parameter is used for all surfaces constituting a target ship. Of course, in order to achieve personalized export and display, the surface precision control parameter corresponding to each surface constituting the target ship can be set separately. The setting method and scope of the surface precision control parameter can be set according to actual needs and are not limited in this embodiment.

[0049] Before exporting the surface data based on the surface precision control parameter, it is necessary to first obtain the surface data of at least one surface constituting the target ship.

[0050] Optionally, surface data of at least one surface associated with the hull of the target ship is imported from the first target software; accordingly, surface precision control parameters are received, including: in response to an editing operation on the surface precision control parameters, obtaining the edited surface precision control parameters related to at least one surface; wherein the surface precision control parameters include the number of discrete points of the surface.

[0051] The first target software may be a software having a three-dimensional drawing function and capable of exporting drawing data in a 3DD file format. Each curved surface has corresponding curved surface data, which corresponds to data related to drawing the curved surface.

[0052] It can be understood that a three-dimensional schematic diagram corresponding to the hull of the ship can be drawn based on the first target software. The three-dimensional schematic diagram can be composed of multiple curved surfaces, and each curved surface has multiple curved surface data. When the curved surface data of all curved surfaces are exported, the solution provided by the embodiment of the present invention can be adopted. Optionally, the curved surface data of at least one curved surface associated with the hull of the target ship stored in the first target software can be used.

[0053] Furthermore, the surface precision control parameters can be set by the user according to actual conditions. Optionally, the display interface can include a surface precision control parameter editing control, and the user can edit the required surface precision control parameters in the surface precision control parameter editing control. After the surface precision parameter editing is completed, the confirmation control can be clicked to obtain the edited surface precision control parameters.

[0054] It should be noted that the number of surfaces constituting the target ship may include multiple surfaces, and the surface precision control parameter corresponding to each surface may be set separately, or all surfaces may correspond to one surface precision control parameter.

[0055] In this embodiment, the surface precision control parameter can be characterized by the number of discretization points. For a surface, it can be composed of multiple points. The more discretization points there are, the higher the coincidence degree of the surface constructed is with the designed surface. Therefore, the higher the number of discretization points, the higher the surface precision control parameter, and vice versa, the lower the surface precision control parameter.

[0056] S120. For surface data of at least one surface, determine surface display parameters of the surface based on the surface data, surface precision control parameters, and an objective function.

[0057] It should be noted that, for each curved surface, the method for determining its curved surface display parameters is the same. In this embodiment, the method for determining the curved surface display parameters of one of the curved surfaces is used as an example for description.

[0058] The surface display parameters are used to characterize the specific parameters of the surface when it is displayed, and the corresponding surface can be displayed according to the surface display parameters. The objective function is a function used to process the surface data and the surface precision control parameters to output the surface display parameters of the surface.

[0059] Specifically, the surface data and the surface precision control parameters may be input into the objective function for calculation, and the surface display parameters of the surface may be obtained.

[0060] In this embodiment, the surface data may include a control point set, a weight set, and a node vector set of the surface.

[0061] It should be noted that for each surface, the parameters of the control point set, weight set and node vector set are somewhat different, and the data of each surface in three dimensions can be obtained. It should also be noted that the surface data has been determined when the drawing is completed, and subsequent processing is only required to obtain the surface data parameters.

[0062] In this embodiment, the surface display parameters of the surface are determined based on the surface data, the surface precision control parameters and the objective function, including: substituting the control point set, the weight set and the node vector set in the surface data, and the number of discretized points in the surface precision control parameters into the basis function for solution operation to obtain the surface display parameters of the surface; wherein the surface display parameters include display information of displayable points consistent with the number of discretized points.

[0063] The basis function may be the objective function mentioned above.

[0064] Specifically, the control point set, weight set and node vector set in the surface data, as well as the number of discretized points in the surface precision control parameters, can be substituted into the basis function corresponding to the objective function for solution operation to obtain the surface display parameters of the surface.

[0065] It should also be noted that the surface display parameters include display information of displayable points that is consistent with the number of discretized points.

[0066] S130, converting the surface display parameters into a target file in a target format, so as to generate a target visualized surface corresponding to the surface precision control parameters based on the target file.

[0067] The target format may be a format corresponding to a 3DD file. The target file may be a 3DD file. The target visualization surface may be generated for the surface display parameters in the target file.

[0068] Specifically, the surface display parameters can be converted into a target file in a target format. After obtaining the target file, a target visualization surface corresponding to the surface precision control parameters can be generated based on the target file. At this time, the surface precision of the target visualization surface is adapted to the surface precision control parameters.

[0069] In this embodiment, converting the curved surface display parameters into a target file in a target format includes: converting the curved surface display parameters corresponding to each curved surface into a target file corresponding to the preset file according to a file standard of a preset file.

[0070] It can be understood that: according to the file standard of the preset file, the surface display parameters of each surface are converted into a target file corresponding to the file format of the preset file.

[0071] In this embodiment, after obtaining the target file, the method also includes: importing the target file into a second target software to process the surface display parameters of each surface in the target file based on the second target software to generate a target visualization surface corresponding to the surface accuracy control parameters.

[0072] Among them, the second target software is the software imported into the CADMATIC outfitting module as the background.

[0073] Specifically, after obtaining the target files of all the surfaces, the target files can be imported into the second target software. The second target software can process the surface display parameters of each surface in the target file to generate a target visualization surface corresponding to the surface precision control parameters.

[0074] The technical solution provided by the embodiment of the present invention receives surface precision control parameters, wherein the surface precision control parameters are used to constrain the display precision of at least one surface constituting a target ship; for surface data of at least one surface, the surface display parameters of the surface are determined based on the surface data, the surface precision control parameters and the objective function; the surface display parameters are converted into a target file in a target format to generate a target visualization surface corresponding to the surface precision control parameters based on the target file, thereby solving the problem in the prior art that the surface data stored in the 3DD file exported by the existing software has low precision, which will cause obvious surface gaps and partial content structure exposure when imported into the CADMATIC outfitting module as a background, resulting in poor display effect of the ship model, and realizing that at least one target surface constituting the ship can be adjusted according to the received surface precision control parameters to obtain a target visualization surface with controllable surface display precision.

[0075] As an alternative embodiment of the above embodiment, Figure 2A schematic diagram of a method for adjusting the display accuracy of a ship surface model provided by an embodiment of the present invention is shown in FIG. Figure 2 As shown,

[0076] Next, we will elaborate on how to generate the target visualization surface with target accuracy.

[0077] Obtain the parameter set of all the surfaces constituting the ship from the first target software (NAPA software). Optionally, the parameter set can be a Nurbs parameter set of the surface. The Nurbs parameter set can be discretized one by one using the number of discrete points on each Nurbs surface as a parameter, and the model data can be converted into a 3DD file of corresponding accuracy based on the definition standard of the 3DD file. Finally, the 3DD file is imported into CADMATIC to control the display accuracy of the surface, and finally the display accuracy of the CADMATIC ship surface model is improved to better meet the design and drawing requirements.

[0078] Figure 3 A flow chart of a method for adjusting the display accuracy of a ship surface model provided in an embodiment of the present invention can be illustrated by taking a specific example based on the above-mentioned embodiment.

[0079] See also Figure 3 , the surface data corresponding to the target ship drawn in the first target software (NAPA software), optionally, the surface data can be a surface Nurbs data set of all surfaces. That is, the surface data of all surface sets constituting the target ship are obtained. The discretization parameters generated by a single surface unit are input, that is, the surface accuracy control parameters of each surface. Traverse the surface set and enter the sub-loop. Get the control point set, weight set and node vector set of a single surface. It should be noted that the above parameters are the data in the surface data. The discretization point parameters and Nurbs surface parameters generated based on a single surface unit are substituted into the basis function for discretization solution calculation. The discretized data 3DD file standard is converted into a 3DD file. The 3DD file is imported into CADMATIC to generate a surface of corresponding accuracy to obtain the final target visualization surface.

[0080] It should be noted that after substituting the surface data of each surface into the basis function solution, the surface solution data of each surface can be converted into a surface in 3DD format. All surface sets in 3DD format can be imported to obtain the final target visualization surface, that is, through CADMATIC surface import.

[0081] The technical solution provided by the embodiment of the present invention receives surface accuracy control parameters, wherein the surface accuracy control parameters are used to constrain the display accuracy of at least one surface constituting a target ship; for surface data of at least one surface, the surface display parameters of the surface are determined based on the surface data, the surface accuracy control parameters and the objective function; the surface display parameters are converted into a target file in a target format to generate a target visualization surface corresponding to the surface accuracy control parameters based on the target file, thereby solving the problem in the prior art that the surface data stored in the 3DD file exported by the existing software has low accuracy, which will cause obvious surface gaps and partial content structure exposure when imported into the CADMATIC outfitting module as a background, resulting in poor display effect of the ship model, and realizing that at least one target surface constituting the ship can be adjusted according to the received surface accuracy control parameters to obtain a target visualization surface with controllable surface display accuracy.
