[0002] Currently, when designing a ship, a three-dimensional design software is usually used to draw the structure of the ship. The ship design is mainly divided into a hull module (including general and structure) and a large outfitting module (including outfitting, machinery and electrical).

[0003] In actual application, a ship body model designed by the hull module is imported into the large outfitting module through an intermediate data format to serve as a background for other professional designs. The ship body model designed by some software is usually based on a 3DD file format to import data into a CADMATIC outfitting module as a background. However, since the 3DD file exported by the software stores low-precision curved surface data, the curved surface joints are obvious and part of the internal structure is exposed after the data is imported into the CADMATIC outfitting module as a background, which affects the model display effect.

[0016] The control point set, the weight set and the node vector set in the curved surface data, and the number of discretization points in the curved surface precision control parameter are substituted into a base function for solving operation to obtain the curved surface display parameter of the curved surface.

[0017] The curved surface display parameter comprises display information of displayable points consistent with the number of discretization points.

[0018] Further, the target file in the target format converted from the curved surface display parameter comprises:

[0019] The curved surface display parameter corresponding to each curved surface is converted into a target file corresponding to the preset file according to a file standard of the preset file.

[0020] Further, after the target file is obtained, the method further comprises:

[0021] The target file is imported into a second target software to process the curved surface display parameter of each curved surface in the target file based on the second target software, and a target visual curved surface corresponding to the curved surface precision control parameter is generated.

[0024] A parameter display module is configured to determine a curved surface display parameter of the curved surface based on the curved surface data, the curved surface precision control parameter and a target function for the curved surface data of the at least one curved surface.

[0025] The surface generation module is used to convert the surface display parameters into a target file of a target format, so as to generate a target visual surface corresponding to the surface accuracy control parameters based on the target file.

[0039] The present application will be further described in detail below in combination with the drawings and embodiments. It can be understood that the specific embodiments described herein are only used to explain the present application, and not to limit the present application. In addition, it should be noted that, in order to facilitate the description, only the parts related to the present application are shown in the drawings, not all the structures.

[0040] The present application will be further described in detail below in combination with the drawings and embodiments. It can be understood that the specific embodiments described herein are only used to explain the present application, and not to limit the present application. In addition, it should be noted that, in order to facilitate the description, only the parts related to the present application are shown in the drawings, not all the structures.

[0041] Before introducing the technical solutions provided by the embodiments of the present application, the application scenario can be exemplarily described.

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

[0043] Figure 1 A flowchart of a ship curved surface model display precision adjustment method provided for an embodiment of the present application. The embodiment can be applied to any scenario that requires the export of a ship structure drawn in software and the adjustment of the precision of the curved surface. The method can be implemented by a ship curved surface model display precision adjustment device integrated in a client or a server in the form of software and / or hardware. The hardware can be an electronic device, such as a PC or a mobile terminal.

[0044] As shown in Figure 1 , the method specifically includes the following steps:

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

[0046] The curved surface precision control parameter can be understood as a parameter that is pre-set to limit the form in which the output curved surface is displayed, i.e., the resolution. Optionally, when the curved surface precision control parameter is a1, it means that the output curved surface precision is adapted to a1. In a more concrete example, if the curved surface precision control parameter is 256, it means that each curved surface constituting the ship needs to be drawn by 256 points when imported and exported. If the curved surface precision control parameter is 512, it means that each curved surface constituting the ship needs to be drawn by 512 points when exported. Generally, the higher the curved surface precision control parameter, the higher the precision requirement for the curved surface, which requires a plurality of points to be determined to draw the exported curved surface. The number of at least one curved surface can be one or more, and the specific number is related to the number of curved surfaces constituting the ship during design.

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

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

[0049] Before the curved surface data is exported based on the curved surface precision control parameter, the curved surface data of at least one curved surface constituting the target ship needs to be obtained.

[0050] Optionally, surface data of at least one surface associated with the hull of the target ship is imported from the first target software; and correspondingly, the surface precision control parameter is received, including: in response to an editing operation on the surface precision control parameter, the edited surface precision control parameter of the at least one surface is obtained; wherein the surface precision control parameter includes the number of discretization points of the surface.

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

[0052] It can be understood that a three-dimensional sketch corresponding to the hull of the ship can be drawn based on the first target software. The three-dimensional sketch can be composed of a plurality of surfaces, and each surface has a plurality of surface data. When exporting the surface data of all surfaces, the scheme provided in the embodiment of the application can be used. Optionally, the surface data of at least one surface associated with the hull of the target ship stored in the first target software can be exported.

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

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

[0055] In this embodiment, the surface precision control parameter can be represented by the number of discretization points. For a surface, it can be composed of a plurality of points, and the more the number of discretization points, the higher the coincidence degree of the surface with the design 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 the surface data of the at least one surface, based on the surface data, the surface precision control parameter and the target function, the surface display parameter of the surface is determined.

[0057] It should be noted that for each surface, the way of determining the surface display parameter thereof is the same, and in this embodiment, the surface display parameter of one of the surfaces is taken as an example for illustration.

[0058] The curved surface display parameter is used to represent specific parameters of the curved surface display, and the corresponding curved surface can be displayed according to the curved surface display parameter. The target function is a function for processing the curved surface data and the curved surface precision control parameter to output the curved surface display parameter of the curved surface.

[0059] Specifically, the curved surface data and the curved surface precision control parameter can be input into the target function for calculation, and the curved surface display parameter of the curved surface can be obtained.

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

[0061] It should be noted that the parameters of the control point set, the weight set and the node vector set of each curved surface are different, and the data in three dimensions of each curved surface can be obtained. It should also be noted that the curved surface data is determined when it is drawn, and subsequent processing can be performed as long as the curved surface data parameters are obtained.

[0062] In this embodiment, the curved surface display parameter of the curved surface is determined based on the curved surface data, the curved surface precision control parameter and the target function, including: substituting the control point set, the weight set and the node vector set in the curved surface data, and the number of discretization points in the curved surface precision control parameter into the base function for solving operation to obtain the curved surface display parameter of the curved surface; wherein the curved surface display parameter includes display information of displayable points consistent with the number of discretization points.

[0063] The base function can be the target function mentioned above.

[0064] Specifically, the control point set, the weight set and the node vector set in the curved surface data, and the number of discretization points in the curved surface precision control parameter can be substituted into the base function corresponding to the target function for solving operation to obtain the curved surface display parameter of the curved surface.

[0065] It should also be noted that the curved surface display parameter includes display information of displayable points consistent with the number of discretization points.

[0066] S130, converting the curved surface display parameter into a target file in a target format to generate a target visual curved surface corresponding to the curved surface precision control parameter based on the target file.

[0067] The target format can be a format corresponding to the 3DD file. The target file can be a 3DD file. The target visual curved surface can be generated based on the curved surface display parameter in the target file.

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

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

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

[0071] In the embodiment, after obtaining the target file, the method further includes: importing the target file into a second target software to process the curved surface display parameters of each curved surface in the target file based on the second target software, and generate the target visual curved surface corresponding to the curved surface precision control parameters.

[0072] The second target software is a software imported into the CADMATIC outfitting module as a background.

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

[0074] The technical solution provided by the embodiment of the application includes the following steps: receiving curved surface precision control parameters, wherein the curved surface precision control parameters are used to constrain the display precision of at least one curved surface constituting a target ship; determining curved surface display parameters of the curved surface based on curved surface data, the curved surface precision control parameters, and a target function for the curved surface data of the at least one curved surface; converting the curved surface display parameters into a target file in a target format to generate a target visual curved surface corresponding to the curved surface precision control parameters based on the target file. The technical solution solves the problem that the curved surface data stored in the 3DD file exported by the existing software has low precision, and when the 3DD file is imported into the CADMATIC outfitting module as a background, the curved surface gap is obvious, part of the content structure is exposed, and the display effect of the ship model is poor. The technical solution realizes that at least one target curved surface constituting a ship can be adjusted according to the received curved surface precision control parameters, and a target visual curved surface with controllable curved surface display precision is obtained.

[0075] As an optional embodiment of the above-mentioned embodiment, Figure 2A schematic diagram of a ship curved surface model display precision adjustment method provided by an embodiment of the present application is shown in Figure 2

[0076] Next, how to specifically generate the target visual curved surface of target precision is described in detail.

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

[0078] Figure 3 A flowchart of a ship curved surface model display precision adjustment method provided by an embodiment of the present application is shown in the foregoing embodiment, which can be described by taking a specific example as an example.

[0079] Referring to Figure 3 The curved surface data corresponding to the target ship drawn from the first target software (NAPA software) is obtained, and optionally, the curved surface data can be the Nurbs data set of all curved surfaces. That is, the curved surface data of all curved surface sets constituting the target ship is obtained. The discretization parameters generated by a single curved surface unit, i.e., the curved surface precision control parameters of each curved surface, are input. The curved surface set is traversed, and a sub-loop is entered. The control point set, the weight set, and the node vector set of a single curved surface are obtained. It should be noted that the above parameters are data in the curved surface data. The discretization point parameters generated by a single curved surface unit and the Nurbs curved surface parameters are substituted into the basis function for discretization calculation. The discretized data 3DD file standard is converted into a 3DD file. The 3DD file is imported into CADMATIC to generate a curved surface of corresponding precision, and the final target visual curved surface is obtained.

[0080] It should be noted that after the curved surface data of each curved surface is substituted into the basis function for solving, the curved surface solving data of each curved surface can be obtained, which can be converted into a 3DD format curved surface. All 3DD format curved surface sets can be imported to obtain the final target visual curved surface to be displayed, i.e., through CADMATIC curved surface import.

[0081] ​The technical scheme provided by the embodiment of the present application comprises the following steps: receiving a curved surface precision control parameter, wherein the curved surface precision control parameter is used to constrain the display precision of at least one curved surface constituting a target ship; determining a curved surface display parameter of the curved surface based on the curved surface data, the curved surface precision control parameter and a target function for the curved surface data of the at least one curved surface; and converting the curved surface display parameter into a target file in a target format, so as to generate a target visual curved surface corresponding to the curved surface precision control parameter based on the target file. The present application solves the problem that the curved surface data stored in the 3DD file exported by the existing software has low precision, and when imported into the CADMATIC outfitting module as a background, the curved surface gap is obvious, part of the content structure is exposed, and the display effect of the ship model is poor. The present application realizes that the at least one target curved surface constituting the ship can be adjusted according to the received curved surface precision control parameter, and the target visual curved surface with controllable curved surface display precision is obtained.

The curved surface generation module 230 is used to convert the curved surface display parameter into a target file in a target format, so as to generate a target visual curved surface corresponding to the curved surface precision control parameter based on the target file.
