Detailed ways

The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the scope of protection of this application.

The terms "first", "second", etc. in the description and claims of this application are used to distinguish similar objects and are not used to describe a specific order or sequence. It is to be understood that data so used are interchangeable under appropriate circumstances so that embodiments of the present application can be practiced in sequences other than those illustrated or described herein. In addition, "and/or" in the description and claims indicates at least one of the connected objects, and the character "/" generally indicates that the related objects are in an "or" relationship.

In order to facilitate a clearer understanding of each embodiment of the present application, some relevant knowledge is first introduced as follows.

3D rendering: 3D models can be displayed on the computer, and operations such as rotation, translation, and scaling can be performed on the 3D models.

Layout files: Display text, pictures, videos and other content in a fixed layout and style. No matter which software is used to open the layout file, the consistency of the displayed content can be guaranteed and the layout will not run out.

At present, if a 3D model needs to be approved and filed, the 3D model needs to be converted into a 2D drawing, and then the relevant reviewers will mark the review information, and then stamp it with a signature to generate a legally valid model annotation file. Or directly integrate the annotations into the model in three-dimensional form.

Using the above technical solution, there may be at least one of the following defects:

(1) Two-dimensional drawings are not intuitive:

Annotations on the 3D model usually indicate the specific position of a specific view, such as the arc size of a front view. Converting to two-dimensional drawings and then annotating them is not as intuitive as annotating directly on three-dimensional drawings. Moreover, it is very inconvenient in terms of data storage, copying, transmission, and retrieval.

(2) There is a lot of annotation data and it is inconvenient to modify:

The approval, proofreading, and verification of equipment and engineering projects is itself a process of continuous revision. There are many comments and suggestions, and repeated revisions are required. If paper drawings are used, a large amount of printing paper is required, which is inconvenient and wasteful. If the 3D model is modified directly, the management process will be coupled to the 3D model too much, and each modification, addition, or deletion of annotation data will destroy the design data of the 3D model itself. And if the annotation data of the 3D model needs to be iterated multiple times, a large amount of data will be modified repeatedly. If the 3D model is a large model, repeated modification of the model will also bring a high load on the software.

Based on this, embodiments of the present application propose a method for storing three-dimensional model annotation data and a method for displaying three-dimensional model annotation data. The annotation data added to the displayed three-dimensional model is stored in association with the identification of the three-dimensional model. , which can avoid the problem of unintuitive two-dimensional drawings and facilitate modification. In addition, since the annotation data is separated from the 3D model and stored in association, it can avoid modifying the 3D model when modifying the annotation, thereby reducing the load on the software.

The technical solutions provided by the embodiments of the present application will be described in detail below with reference to the accompanying drawings through specific embodiments and application scenarios.

Figure 1 is a schematic flowchart of a method for storing three-dimensional model annotation data provided by an embodiment of the present application. The method 100 can be executed by a first electronic device. In other words, the method may be performed by software or hardware installed on the first electronic device.

In this embodiment of the present application, the first electronic device can be installed with layout file reading software, and the user can log in using his or her account when using the first electronic device.

As shown in Figure 1, this method mainly includes the following steps:

S102. In response to receiving the target operation, the first electronic device acquires the three-dimensional data of the target three-dimensional model from the target layout file, and displays the target three-dimensional model based on the three-dimensional data.

For example, the user can use the layout file reading software to input a target operation for displaying the target three-dimensional model, and then the first electronic device responds to the target operation input by the user and obtains the three-dimensional data of the target three-dimensional model from the target layout file.

In this embodiment of the present application, optionally, before S102, the three-dimensional data of the target three-dimensional model can be inserted into the layout file, thereby obtaining the above-mentioned target layout file. For example, the user can use layout file reading software to open or create a new layout file. The layout file can be a blank file without any data. Among them, the three-dimensional model file can be obtained during the design process of the three-dimensional model. In the embodiment of this application, the three-dimensional model may be an industrial equipment model or an equipment model in other fields. In the process of designing a three-dimensional model, the data of the three-dimensional model may be involved, for example, three-dimensional data such as product size information, product supporting information, process equipment information, and consumable information. Then, the three-dimensional data of the target three-dimensional model is obtained from the three-dimensional model file, and then the three-dimensional data is inserted into the above-mentioned layout file to obtain the target layout file. As a result, the three-dimensional data is saved in the target layout file, and the three-dimensional data can be displayed in the target layout file with a fixed layout and style to avoid running out of layouts.

Optionally, after inserting the three-dimensional data into the target layout file, you can also add data signature information to the target layout file. Before performing the acquisition of the three-dimensional data of the target three-dimensional model from the target layout file in S102, you can first sign the data. The information is verified, and after the verification is passed, the operation of obtaining the three-dimensional data of the target three-dimensional model in the target layout file is performed, thereby ensuring that the obtained three-dimensional data has not been illegally tampered with.

In S102, after obtaining the three-dimensional data of the target three-dimensional model, the target three-dimensional model can be rendered and displayed based on the three-dimensional data.

S104. In response to the annotation operation on the target three-dimensional model, obtain annotation data.

In this embodiment of the present application, the annotation data includes but is not limited to: the location information of the operation point corresponding to the annotation operation, the operation view corresponding to the annotation operation, the annotation content information of the annotation operation, the annotation operation The operation time and the identity information of the operator of the annotation operation.

After displaying the target three-dimensional model, the user can perform an annotation operation based on the displayed target three-dimensional model, and the first electronic device obtains annotation data for the annotation operation.

For example, user Zhang San can click the operation of adding annotation at a certain operation point on the display page of the target 3D model, and enter the annotation content as follows: It is recommended that the plane roughness be changed to 0.8, then the first electronic device may obtain the information as shown in Figure 2 the annotation data shown.

S106: Associate the annotation data with the identification of the target three-dimensional model and save it in the target layout file.

In the embodiment of the present application, after obtaining the annotation data, the annotation data is associated with the identification of the target 3D model and then saved in the target layout file, so that when the target 3D model is opened, the annotations of the target 3D model can be obtained and displayed. data.

In a possible implementation, before S104, the method may further include: verifying the identity information to determine that the user corresponding to the identity information has the annotation authority.

In a specific application, the above annotation operation may be an operation of adding annotation or an operation of modifying annotation, which is not limited in the specific embodiment of the present application.

In the above implementation method, the annotation operation on the target 3D model will be responded to only after it is verified that the user corresponding to the identity information has the annotation authority, so that only relevant persons who have passed the identity authentication can perform annotation data generation and modification operations. Others can view the annotation data during the transfer of the 3D model. This can prevent people without permission from adding annotation data to the 3D model.

In a possible implementation, in order to ensure the validity of the annotation data, after S104, the method may also include the following steps:

Step 1: Obtain the signature private key bound to the identity information.

In specific applications, the signature private key bound to the identity information can be stored in the server, or, in order to ensure the security of the signature private key, the signature private key can also be stored in a security device, for example, in an electronic signature device. An electronic device can obtain the signature private key bound to the identity information from the server through the network, or an external interface, such as a USB interface, is connected to the electronic signature device to obtain the signature private key from the electronic signature device.

Step 2: Use the signature private key to perform data signature on the annotation data to obtain the signature data of the annotation data.

In step 2, a predetermined signature algorithm may be used to perform data signature on the annotation data to obtain signature data of the annotation data. The specific signature algorithm is not limited in the embodiments of this application.

Step 3: Associate the signature data with the identification of the target three-dimensional model and save it in the target layout file.

Through the above implementation method, the identification of the target three-dimensional model can be associated and saved with the annotation data and the signature data of the annotation data, so that the corresponding annotation data and signature data can be obtained when the target three-dimensional model is loaded.

Figure 3 shows a schematic flowchart of a method for displaying three-dimensional model annotation data provided by an embodiment of the present application. As shown in Figure 3, the method mainly includes the following steps.

S302. In response to the received target operation, the second electronic device acquires the three-dimensional data of the target three-dimensional model from the target layout file, and displays the target three-dimensional model based on the three-dimensional data.

For example, the second electronic device can open the target version file through layout reading software, load the target three-dimensional model and display it. The second electronic device and the first electronic device may be the same device or they may be different devices.

S304: According to the identification of the target three-dimensional model, obtain the annotation data associated with the identification from the target version mode, wherein the annotation data includes: the position information of the operation point corresponding to the annotation operation, the annotation The operation view corresponding to the operation, the annotation content information of the annotation operation, the operation time of the annotation operation, and the identity information of the operator of the annotation operation.

The above annotation data can be stored in association with the target three-dimensional model using the method shown in Figure 1. For details, please refer to the above relevant descriptions, which will not be described again here.

S306: Based on the location information and the operation view, display the annotation content information, the operation time and the identity information to the corresponding position of the target three-dimensional model.

For example, based on the annotation data shown in Figure 2, the content finally displayed by the second electronic device may be as shown in Figure 4.

In a possible implementation, in order to determine whether the annotation data has been tampered with, based on the location information and the operation view, the annotation content information, the operation time and the identity information are displayed to the Before determining the corresponding position of the target three-dimensional model, the method further includes the following steps:

Step 1: Query the signature public key corresponding to the identity information.

In a specific application, the signature public key corresponding to the identity information can be stored in the server, and the second electronic device can obtain the signature public key through the server.

Step 2: Perform signature verification on the signature data associated with the identification of the target three-dimensional model stored in the target layout file based on the signature public key and the annotation data, and the verification passes.

In specific applications, the signature verification algorithm corresponding to the above signature algorithm can be used to verify the signature data stored in the target format file. If the verification passes, it means that the signature data has not been tampered with and is legal data.

In a possible implementation, the method may further include: determining that the annotation data is invalid if the signature public key corresponding to the identity information is not queried. If the signature public key corresponding to the identity information is not queried, it can be determined that the annotation data is not legal annotation data, and therefore, the annotation data is determined to be invalid.

In a possible implementation, the method may further include: determining that the annotation data is invalid if the signature verification of the signature data fails. If the signature verification of the tax data fails, it can be determined that the annotation data has been tampered with, or is not annotation data added by the user corresponding to the identity information, and therefore, the annotation data is deemed invalid.

In the technical solution provided by the embodiment of this application, in order to realize the management of annotation data, the roles, permissions and keys of the information management system can be managed. As shown in Figure 5, role management is used to manage various roles, and Permission management authorizes the permissions of various roles. Only designated roles can add or modify comments, while key management manages the user's private signing key and public signing key. As shown in Figure 5, the 3D model data is stored in the layout file. After loading the 3D model, the user can add annotation 1, and then after verifying the user's permissions and confirming that the user can add or modify the annotation, confirm that the user has added Annotation 1, and then use the user private key in key management to sign annotation 1, and finally store the 3D model data, annotation data and signature data in the annotation document database.

The technical solution provided by the embodiment of the present application will be described below with reference to FIG. 5 .

As shown in Figure 6, this method mainly includes the following steps:

Step 601: The first operator obtains the three-dimensional model from the target layout file and loads it into the three-dimensional model display software for display.

Step 602: Verify the first operator's corporate identity role. If the verification fails, the person is not allowed to operate the annotation. If the verification passes, load the signature private key bound to the employee's identity from the enterprise key management system. key.

Step 603: After reviewing the model, the first operator annotates the three-dimensional model. The data recorded in the annotation includes: three-dimensional interactive information such as the three-dimensional coordinates of the operating point position and the operating view, as well as event record information such as operating time and operator identity.

Step 604: When the annotation is completed, the above data is saved in the target layout file, and the private key in step 602 is used to perform signature calculation on the annotation data. After the calculation is completed, the signature data is also saved in the target layout file.

Step 605: Associate annotation data and signature data with the three-dimensional model ID.

Step 606: The second operator obtains the three-dimensional model from the target layout file and loads it into the model display software for display.

The first operator and the second operator may perform the same operation, or may be different operators.

Step 607: Obtain corresponding annotation data and signature data from the target layout file according to the three-dimensional model ID.

Step 608: Based on the annotation operator information, query the information system for the person's public key information, and use the public key to perform signature verification on the annotation information. If the public key cannot be queried or the signature verification fails, it means that the annotation information is invalid. If the verification passes, the annotation is valid. Annotations can be displayed in conjunction with the 3D model.

For example, you can first load and display the 3D model, and then dynamically attach the content, operator, time and other information of the annotation to the 3D scene based on the operation view recorded in the annotation and the 3D coordinates of the annotation.
