[0002] In the process of modeling ship data using ship modeling software, in order to improve efficiency, the data of the source model is usually processed by reference replication to obtain multiple reference replication models.

[0003] However, the above method has the following two problems. First, when the reference copy model is converted and output based on general formats such as IFC and STP, since the reference copy model only contains the entity data of the source model and the parameters of the reference copy model, the corresponding entity model cannot be directly generated. Second, in the case where a reference copy model needs to be modified, since multiple reference copy models are copied based on the principle of reference replication, the reference copy models can only be modified one by one, and the linkage modification of multiple reference copy models cannot be achieved. Furthermore, the above-mentioned modification of the reference copy models one by one affects the efficiency of model processing. Summary of the invention

[0030] Embodiment 1

[0031] Figure 1 This is a flowchart of a method for converting a reference replica model into a physical model provided by the first embodiment of the present invention. This embodiment can be applied to converting a reference replica model in ship design to ensure complete data expression. The method can be executed by a device for converting a reference replica model into a physical model. The device for converting a reference replica model into a physical model can be implemented in the form of hardware and / or software. The device for converting a reference replica model into a physical model can be configured in electronic devices such as mobile phones, computers or servers. Figure 1 As shown, the method includes:

[0032] S110. If it is determined based on the geometric object set of the initial model that an object element corresponding to the reference copy object exists, then element index information of the object element is obtained.

[0033] The reference copy object is an object obtained by copying the source object in the target ship. The target ship may be the currently selected ship that needs to be converted into a model. The initial model may be understood as the original model corresponding to the target ship. The geometric object set may be a set of geometric objects corresponding to the components constituting the target ship. For example, taking the bolts on the hull as an example, the geometric object set may include different types of geometric bodies such as cylinders, prisms, and hemispheres. The source object is the original object in the geometric object set. The reference copy object is an object obtained by copying the source object by reference. For the geometric object set, different categories of geometric objects have different category labels. According to the category labels corresponding to the reference copy objects, which ones are reference copy objects are determined from the geometric object set. The object element of the reference copy object is used to characterize the reference copy object in the geometric object set. The element index information is used to locate the object element corresponding to the reference copy object from the geometric object set. Optionally, the element index information may be an integer, a string, etc. For example, the element index information may be k, k=300, that is, the object element of the reference copy object is the 300th object element in the geometric object set.

[0034] Specifically, since the category labels corresponding to geometric objects of different categories in the geometric object set are different, when the geometric object set corresponding to the initial model is received, the geometric object set is traversed according to the category label corresponding to the reference copy object, and the object element corresponding to the reference copy object in the geometric object set is determined, and the element index information of the object element is obtained.

[0035] Exemplarily, when the geometric object set entities of the initial model is obtained, the geometric object set is traversed, and according to the category label corresponding to the reference copy object, it is determined whether there is a reference copy object in the geometric object set. If there is a reference copy object, the object element entities[k] corresponding to the reference copy object and the element index information k of the object element are determined.

[0036] S120 , retrieving a source object set and reference replication parameters of a reference replication object according to the element index information, determining target replication data corresponding to the reference replication object, and updating the target replication data to a pre-created temporary storage object set.

[0037] Among them, the source object set can be understood as a set of source objects corresponding to the reference copy object. The reference copy parameters can be understood as various parameters corresponding to the reference copy object. Optionally, the reference copy parameters may include information such as the number of copies of the reference copy object, the offset distance, and the offset angle. The target copy data may be a geometric instance object obtained by recursively transforming the reference copy object. The temporary storage object set may be a pre-created geometric object set for storing the target copy data.

[0038] Specifically, the source object set corresponding to the reference copy object and the reference copy object's reference copy parameters such as offset distance, offset angle and copy quantity are retrieved according to the reference copy object. According to the source object set and the reference copy parameters, the source objects in the source object set are recursively transformed to obtain the target copy data corresponding to the reference copy object. The target copy data is temporarily stored in a pre-created temporary storage object set.

[0039] Exemplarily, in combination with the above example, in order to prevent data loss or tampering, the reference copy object can be deep copied to perform subsequent processing based on the deep copied reference copy object. According to the element index information k of the reference copy object, the source object set is retrieved and the reference copy parameters such as the number of copies, direction vector, offset distance and offset angle of the reference copy object are obtained. According to the reference copy parameters, the points and vectors of each source object in the source object set are recursively transformed to obtain the target copy data. The target copy data is stored in the pre-established temporary storage object set NewEntities.

[0040] S130. Update the geometric object set based on the temporary storage object set, so as to generate a solid model corresponding to the reference copy object based on the updated geometric object set.

[0041] The entity model can be a entity model obtained after all reference copy objects are solidified. For example, the entity model can be found in Figure 2 The dark blue part of the model.

[0042] Specifically, according to the element index information of the reference copy object corresponding to the target copy data in the temporary storage object set, the target copy data is updated to the object element position corresponding to the geometric object set to obtain an updated geometric object set. All the target copy data in the updated geometric object set are solidified to generate a solid model corresponding to the reference copy object.

[0043] Optionally, the method of updating the geometric object set may be: based on the element index information corresponding to the target copy data, the target copy data in the temporary storage object set is updated to the object element corresponding to the element index information in the geometric object set.

[0044] Specifically, according to the element index information corresponding to the target copy data, the object element corresponding to the element index information in the geometric object set is removed, and the target copy data in the temporary storage object set is inserted into the object element corresponding to the element index information.

[0045] Exemplarily, in combination with the above example, according to the element index information k of the reference copy object, the object element corresponding to the element index information k in the geometric object set is removed, and the target copy data in the temporary storage object set NewEntities is inserted into the element index information k to obtain an updated geometric object set. All reference copy objects in the updated geometric object set are solidified to obtain a solid model corresponding to the reference copy object.

[0046] The technical solution of this embodiment is to obtain the element index information of the object element when it is determined that there is an object element corresponding to the reference copy in the geometric object set of the initial model. The source object set and the reference copy parameters of the reference copy object are retrieved according to the element index information, the target copy data corresponding to the reference copy object is determined, and the target copy data is updated to the pre-created temporary storage object set. The geometric object set is updated based on the temporary storage object set to generate a solid model corresponding to the reference copy object based on the updated geometric object set, thereby achieving accurate conversion from the reference copy model to the solid model, solving the problem in the prior art that the solid model cannot be directly generated and the problem that multiple reference copy models cannot be modified in a linked manner. The above-mentioned method of determining the solid model ensures the quality of model transmission between heterogeneous platforms, providing a data basis for collaborative ship production.

[0047] Embodiment 2

[0048] Figure 3 This is a flowchart of a method for converting a reference copy model into a physical model provided by the second embodiment of the present invention. This embodiment is based on the above embodiment and refines the step of "calling the source object set and the reference copy parameters of the reference copy object according to the element index information to determine the target copy data corresponding to the reference copy object". The specific implementation method can be found in the technical solution of this embodiment. Among them, the technical terms that are the same or corresponding to the above embodiment are not repeated here. Figure 3 As shown, the method includes:

[0049] S210. If it is determined based on the geometric object set of the initial model that an object element corresponding to the reference copy object exists, then element index information of the object element is obtained.

[0050] S220. Retrieve a source object set based on the element index information, wherein the source object set is used to store object composition parameters of a source object to which the reference copy object belongs.

[0051] The object composition parameters may include coordinate data and vectors of points constituting the source object. For example, taking the source object as a cylinder, the object composition parameters may include the coordinates of the bottom point of the cylinder and the vector corresponding to the cylinder itself.

[0052] Specifically, the object composition parameters of the source object to which the reference copy object belongs are retrieved according to the element index set, so as to perform subsequent coordinate system transformation processing based on the object composition parameters in the source object set.

[0053] S230. For the object composition parameters, based on the offset vector, offset distance and offset angle in the reference replication parameters, determine the coordinate information and coordinate system transformation rotation quaternion corresponding to the object composition parameters.

[0054] Among them, the offset vector can be understood as the moving direction vector corresponding to the coordinate system transformation. For example, the offset vector can be used to indicate in which direction the coordinates are moved. The offset distance can be understood as the moving distance corresponding to the coordinate system transformation. The offset angle can be the moving angle corresponding to the coordinate system transformation. The coordinate information can be the coordinate data corresponding to the object composition parameters. For example, the coordinate information can be the entity coordinate origin of the coordinate system where the object composition parameters are located. The coordinate system transformation rotation quaternion can be a quaternion used to perform a three-dimensional coordinate system transformation on the object composition parameters.

[0055] Specifically, by referring to the offset vector, offset distance and offset angle in the replication parameters, the corresponding coordinate information and coordinate system transformation rotation quaternion are determined during the coordinate system transformation, so as to perform coordinate system transformation processing on the object composition parameters based on the coordinate information and the coordinate system transformation rotation quaternion.

[0056] S240 . Determine reference copy data corresponding to the object composition parameters and the reference copy object based on the coordinate information corresponding to the object composition parameters and the coordinate system transformation rotation quaternion.

[0057] The reference replication data may be data obtained after coordinate system transformation of the object composition parameters. For example, the reference replication data may include points and vectors after coordinate system transformation.

[0058] Specifically, according to the coordinate information of the object composition parameters and the coordinate system transformation rotation quaternion, recursive coordinate system transformation processing is performed on each object composition parameter of the source object to determine the transformed reference replication data. Based on this, the coordinate system transformation processing of each source object to which the reference replication object belongs is realized.

[0059] It should be noted that, since object constituent parameters may be recursively nested when coordinate system transformation is performed, the object constituent parameters may be recursively transformed.

[0060] Exemplarily, the source object set is traversed, and the coordinates and vectors of the points in each source object corresponding to the reference copy object are recursively transformed to obtain the coordinate data of the transformed points and the transformed vectors, ie, the reference copy data.

[0061] In an embodiment of the present invention, the method for determining the reference replication data can be: based on the initial coordinate system of the object composition parameters and the coordinate system transformation rotation quaternion, determining the target coordinate system of the object composition parameters under the replication reference object; determining the target coordinates of the initial coordinates of the object composition parameters in the initial coordinate system in the target coordinate system; based on the object composition parameters and the target coordinates, determining the reference replication data of the object composition parameters under the reference replication object.

[0062] The initial coordinate system can be understood as the coordinate system corresponding to the source object. The target coordinate system is the coordinate system corresponding to the reference copy object. The initial coordinates are the coordinate data of the object composition parameters in the initial coordinate system. The target coordinates are the coordinates of the points in the object composition parameters in the target coordinate system.

[0063] Specifically, according to the initial coordinate system of the object composition parameters under the source object and the coordinate system transformation rotation quaternion, the target coordinate system of the object composition parameters under the copy reference object is determined. According to the initial coordinates of the object composition parameters under the initial coordinates, the coordinate system transformation rotation quaternion is used to determine the target coordinates of the object composition parameters in the target coordinate system. According to the object composition parameters and the target coordinates, the reference copy data is obtained.

[0064] S250 . Determine target replication data of the reference replication object based on the reference replication data of each object constituent parameter, and update the target replication data into a pre-created temporary storage object set.

[0065] Specifically, since each source object can contain one or more object composition parameters, the target copy data of the reference copy object corresponding to the source object can be determined based on the reference copy data of each object composition parameter corresponding to the source object, and the target copy data can be stored in a temporary storage object set to entity the target copy data in the temporary storage object set to obtain an entity model.

[0066] Optionally, based on the reference replication quantity in the reference replication parameter, the object composition parameter is processed to obtain target replication data corresponding to each reference replication object.

[0067] The reference replication number can be understood as the number of the same reference replication objects. For example, if the reference replication object is a cylinder and the reference replication number of the cylinder is five, it means that the source object corresponding to the reference replication object needs to be transformed into the coordinate system five times to obtain five target replication data.

[0068] Specifically, according to the reference replication number in the reference replication parameter, the coordinate system transformation processing is performed on the object composition parameter to obtain the target replication data of the current reference replication object. Based on this, the target replication data corresponding to the parameter replication number is obtained, and the linkage modification of multiple reference replication models is realized, which improves the efficiency of model processing.

[0069] S260: Update the geometric object set based on the temporary storage object set, so as to generate a solid model corresponding to the reference copy object based on the updated geometric object set.

[0070] The technical solution of this embodiment is to obtain the element index information of the object element when it is determined that there is an object element corresponding to the reference copy in the geometric object set of the initial model. The source object set is retrieved based on the element index information, wherein the source object set is used to store the object composition parameters of the source object to which the reference copy object belongs, and provide a transformation object for the subsequent coordinate system transformation. For the object composition parameters, the coordinate information corresponding to the object composition parameters and the coordinate system transformation rotation quaternion are determined based on the offset vector, offset distance and offset angle in the reference copy parameters, and a transformation method is provided for the subsequent coordinate system change. Based on the coordinate information corresponding to the object composition parameters and the coordinate system transformation rotation quaternion, the reference copy data corresponding to the object composition parameters and the reference copy object are determined. Based on the reference copy data of each object composition parameter, the target copy data of the reference copy object is determined, and the target copy data is updated to the pre-created temporary storage object set. Based on the temporary storage object set, the geometric object set is updated to generate a solid model corresponding to the reference copy object based on the updated geometric object set, so as to realize the accurate conversion of the reference copy model to the solid model, and solve the problem that the solid model cannot be directly generated in the prior art and the problem that multiple reference copy models cannot be modified in a linked manner. By determining the entity model in the above manner, the quality of model transfer between heterogeneous platforms is ensured, providing a data basis for collaborative ship production.

[0071] Embodiment 3

[0072] Figure 4This is an example diagram of a method for converting a reference replica model into a physical model provided by the third embodiment of the present invention. This embodiment is an optional embodiment of the above embodiment. The specific implementation method can refer to the technical solution of this embodiment. Among them, the technical terms that are the same or corresponding to the above embodiment are not repeated here. Next, combined with Figure 4 To illustrate the technical solution provided by the embodiment of the present invention:

[0073] First, the geometric object set of the initial model is traversed to determine the reference copy object and the object index information corresponding to the reference copy object.

[0074] The object index information is the element index information mentioned in the above embodiment.

[0075] Specifically, when the parser receives the geometric object set entities of the initial model, it determines whether there is a reference copy object in the geometric object set. If there is no reference copy object, the geometric object set entities is returned. If there is a reference copy object, the geometric object set is traversed to determine the current geometric object entities[k] and object index information. The object type of the current geometric object is determined to determine whether the current geometric object is a reference copy object. If the current geometric object is a reference copy object, the object index information k of the current geometric object is used as the object index information k of the reference copy object, so as to perform sub-loop processing based on the reference copy object entities[k] and the object index information k. Among them, the object type corresponds to the category label mentioned in the above embodiment.

[0076] Secondly, a deep copy process is performed on the reference copy object to obtain a deep copy object, and the deep copy object is parsed to obtain reference copy parameters corresponding to the reference copy object.

[0077] The deep copy object is an object obtained by copying the reference copy object. The content of the deep copy object is consistent with the content of the reference copy object.

[0078] Specifically, a deep copy process is performed on the reference copy object to obtain a duplicate object. The duplicate object is parsed to obtain reference copy parameters such as the origin of the coordinate system, direction vector, spacing, angle, and number of copies corresponding to the reference copy object. Among them, the direction vector is the offset vector mentioned in the above embodiment. The spacing is the offset distance mentioned in the above embodiment. The angle is the offset angle mentioned in the above embodiment. The number of copies is the reference copy number mentioned in the above embodiment.

[0079] Next, a loop is performed based on the reference copy parameters to determine the offset coordinate origin and the coordinate system transformation rotation quaternion.

[0080] The offset coordinate origin corresponds to the coordinate information of the object constituent parameters mentioned in the above embodiment.

[0081] Specifically, the offset coordinate origin and coordinate system transformation quaternion are calculated according to the direction vector, spacing, angle, etc. in the reference replication parameters. According to the number of replications in the reference replication parameters, the offset coordinate origin and coordinate system transformation quaternion corresponding to each reference replication object are determined.

[0082] After that, the source object set corresponding to the reference copy object is traversed, and the points and vectors in each source object are recursively transformed to obtain the transformed points and vectors. The deep copy object is updated based on the transformed points and vectors, and the transformed points and vectors are updated to the pre-created new geometric object set.

[0083] The points and vectors in the source object correspond to the object composition parameters mentioned in the above embodiment. The transformed points and vectors correspond to the reference replication data mentioned in the above embodiment. The pre-created new geometric object set corresponds to the temporary storage object set mentioned in the above embodiment.

[0084] Specifically, traverse the reference copy object set corresponding to the duplicate object, and perform deep copy processing on the reference copy object set to obtain the entity object. According to the offset coordinate origin and coordinate system rotation quaternion, recursively transform the points and vectors in each entity object to obtain the transformed points and vectors. Add the transformed points and vectors to the pre-created new geometric object set NewEntities. In addition, modify the references of the points and vectors in the entity object to the transformed points and vectors. Add the entity object to the new geometric object set NewEntities.

[0085] Next, the reference copy object corresponding to the object index information in the geometric object set of the initial model is removed, and the geometric object set of the initial model is updated according to the new geometric object set.

[0086] Specifically, the reference copy object at the object index information k in the geometric object set entities of the initial model is removed, and the new geometric object set NewEntities after the data is added is inserted into the object index information k.

[0087] Finally, a mirrored solid model is generated according to the updated geometric object set of the initial model.

[0088] The mirror image entity model is the entity model mentioned in the above embodiment.

[0089] Specifically, a mirror entity model is generated according to the updated geometric object set entities.

[0090] The technical solution of this embodiment is to determine the reference copy object and the object index information corresponding to the reference copy object by traversing the geometric object set of the initial model in the parent loop after the initial model geometric object set and enter the sub-loop. In the sub-loop, the reference copy object is deep copied to obtain the deep copy object and determine the reference copy parameters corresponding to the deep copy object. Based on the reference copy parameters, the points and vectors in each source object are recursively transformed to obtain the transformed points and vectors and add them to the new geometric object set in sequence. Based on this, the complete data expression of the reference copy object is realized. Then the sub-loop is jumped out. In the parent loop, the new geometric object set generated by the sub-loop is inserted into the corresponding position of the object index information of the geometric object of the initial model, and the original reference copy object is deleted synchronously. According to the updated geometric object set of the initial model, a mirrored entity model is generated, and the accurate conversion from the reference copy model to the entity model is realized, which solves the problem that the entity model cannot be directly generated in the prior art and the problem that multiple reference copy models cannot be modified in a linked manner. Through the above-mentioned method of determining the entity model, the quality of model transmission between heterogeneous platforms is guaranteed, and a data basis is provided for collaborative production of ships.

The above-mentioned method of determining the solid model ensures the quality of model transmission between heterogeneous platforms, providing a data basis for collaborative ship production.
