The traditional cultural relic restoration method is mainly characterized in that a manual restoration method is adopted to truly restore the cultural relic. With this repair method, the following problems inevitably arise: 1) because the repair is carried out manually, the repair cost is high and the repair time is long; 2) because the repairing effect depends on the repairing experience of a repairing person, such as: the personal cognitive ability of the repairmen to the whole cultural relics, the personal technical ability of the repairmen in the repairing process and the like, so that great uncertainty exists in the cultural relics repairing process, and the repairing accuracy cannot be guaranteed.

Detailed Description

In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present application. This application is capable of implementation in many different ways than those herein set forth and of similar import by those skilled in the art without departing from the spirit and scope of this application, and it is therefore not limited to the specific implementations disclosed below.

In the application, three cultural relic repair methods, three cultural relic repair devices, three electronic devices and two cultural relic repair systems are provided. Details are described in the following examples one by one.

The basic idea of the cultural relic repair method provided by the application is as follows: the method comprises the steps of automatically generating at least one repairing scheme corresponding to each part to be repaired respectively according to actual three-dimensional model data of each part to be repaired of a designated cultural relic, a pre-stored historical actual three-dimensional model data set and at least one historical repairing scheme corresponding to the historical actual three-dimensional model data, and displaying a virtual repairing effect picture with a space sense formed after each part to be repaired adopts various repairing schemes to a user through virtual reality display equipment. Because the cultural relics can be repaired without depending on the repairing personnel, the repairing process is independent of the individual repairing experience of the repairing personnel, and a user can personally observe and experience the virtual repairing effect with the sense of space formed after each part to be repaired is repaired by adopting each repairing scheme, the cultural relics repairing cost can be effectively reduced, and the repairing efficiency and the repairing accuracy are improved.

Please refer to fig. 1, which is a flowchart illustrating a first method for repairing cultural relics according to an embodiment of the present application. The method comprises the following steps:

step S101: and acquiring a data set of the part to be repaired of the specified cultural relic.

To implement the cultural relic repair method provided by the application, a data set of a part to be repaired of a specified cultural relic needs to be acquired. The data set of the parts to be repaired of the specified historical relic comprises data of all parts needing repair of the specified historical relic, such as part identification of the parts to be repaired.

As an alternative, the data set of the part to be repaired of the designated cultural relic may be a data set formed by data of the part to be repaired directly designated by a repairing person, for example, after the repairing person actually surveys the cultural relic and evaluates the actual survey result, the repairing person directly determines which parts need to be repaired and which parts do not need to be repaired, and directly forms the data set of the part to be repaired according to the determination result. However, since the solution requires a repairman to actually survey the cultural relics themselves, there are problems of high surveying cost, low surveying efficiency and low surveying result accuracy.

In order to solve the problems of the above alternatives, the data set of the parts to be repaired of the specified cultural relics can be automatically generated by the computing device. To realize automatic generation of a data set of a part to be repaired of a specified cultural relic, the following steps can be adopted: 1) acquiring actual three-dimensional model data of each preset part of the specified cultural relic; 2) aiming at each preset part, comparing the actual three-dimensional model data of the preset part with the pre-stored original three-dimensional model data of the preset part, and acquiring the defect rate of the actual three-dimensional model of the preset part; judging whether the defect rate is larger than a preset defect rate threshold value of the preset component or not; if the judgment result is yes, determining the preset component as a component to be repaired; 3) and generating the data set of the component to be repaired according to the determined component to be repaired.

In specific implementation, the actual three-dimensional model data of each preset part of the appointed cultural relic can be acquired through a preset scanning technology.

In specific implementation, after the defect rate of the actual three-dimensional model of a preset component is determined to be greater than the defect rate threshold of the component, the actual three-dimensional model of the virtual reality of the component can be firstly displayed to a user, the user can send a confirmation instruction after observing the actual three-dimensional model with the spatial sense of the component through a virtual reality display device, if the confirmation instruction is an instruction for determining the component as the component to be repaired, the operation for determining the component as the component to be repaired is executed, and otherwise, if the confirmation instruction is an instruction for determining the component as the component not to be repaired, the operation for determining the component as the component to be repaired is not executed. By adopting the processing mode, the user can intervene in the final determination result of the part to be repaired, so that the effect of improving the user experience is achieved.

In addition, in order to improve the flexibility of determining the part to be repaired, when the defect rate of the actual three-dimensional model of a preset part is less than or equal to the defect rate threshold of the part, the part can be determined as the part to be repaired according to a forced repair instruction input by a user. By adopting the processing mode, the user can intervene in the final determination result of the part to be repaired, and the user experience can be further improved.

After the data set of the part to be repaired of the specified cultural relic is acquired, the next step can be entered, and at least one repairing scheme corresponding to each part to be repaired is generated according to the actual three-dimensional model data of the part to be repaired, the pre-stored historical actual three-dimensional model data set and at least one historical repairing scheme corresponding to the historical actual three-dimensional model data.

Step S103: and generating at least one repairing scheme corresponding to each part to be repaired according to the actual three-dimensional model data of the part to be repaired, the pre-stored historical actual three-dimensional model data set and at least one historical repairing scheme corresponding to the historical actual three-dimensional model data.

According to the cultural relic repair method provided by the embodiment of the application, the repair scheme of the part to be repaired can be learned from the historical maintenance record of the cultural relic in a machine learning mode. To realize the function of learning the repair scheme of the part to be repaired from the historical repair record, at least three aspects of data are needed: actual three-dimensional model data of the component to be repaired, a historical actual three-dimensional model data set and a historical repair scheme corresponding to the historical actual three-dimensional model data.

The actual three-dimensional model data refers to the three-dimensional model data of the state of the cultural relic when the three-dimensional model data of the specified cultural relic is acquired.

The historical actual three-dimensional model data set may be a data set including only historical actual three-dimensional model data of each preset part of the designated cultural relic, or may be a data set including historical actual three-dimensional model data of each preset part of at least one preset cultural relic of the same kind as the designated cultural relic.

As a preferable scheme, the historical actual three-dimensional model data set may be formed according to historical actual three-dimensional model data of each preset part of the designated cultural relic; in the processing mode, the historical actual three-dimensional model data is historical data of the same cultural relic, and the data entries in the data set are fewer; therefore, the accuracy of the generated restoration scheme can be effectively ensured, and the generation speed of the restoration scheme can be improved.

It should be noted that, to ensure the implementation effect of the preferred embodiment, it is premised on that sufficient historical actual three-dimensional model data needs to be generated in advance. In order to obtain sufficient historical actual three-dimensional model data, corresponding three-dimensional model data can be simulated according to various possible damage degrees of the cultural relics and used as the historical actual three-dimensional model data, and a corresponding repairing scheme is set for the historical actual three-dimensional model data. In addition, in order to show the repairing effect which can be achieved by adopting the repairing scheme, the repairing scheme described by the characters is converted into a corresponding image processing instruction, and the repaired three-dimensional model can be generated by executing the corresponding image processing instruction on the historical actual three-dimensional model data.

As an alternative, the historical actual three-dimensional model data set may be formed according to historical actual three-dimensional model data of each preset part of at least one preset cultural relic of the same kind as the specified cultural relic; in the processing mode, the historical actual three-dimensional model data is derived from a plurality of similar cultural relics, and the data items in the data set are more. Compared with the optimal scheme, the accuracy of the repair scheme generated by the scheme may be poor, and the generation speed of the repair scheme may be low.

The historical actual three-dimensional model data corresponds to at least one historical repair scheme, different historical repair schemes may correspond to different repair result fault tolerance rates, for example, for a hand of 'Temple Buddha', multiple repair schemes may be adopted for repair, and the fault tolerance rates which can be achieved by different repair schemes may be different.

In specific implementation, different repair result fault tolerance rates can be set for different parts of a specified cultural relic, namely: the repair result fault tolerance rates corresponding to the components can be uniformly set to be the same value, and different repair result fault tolerance rates can be set for the components according to the characteristics of the components. The fault tolerance of the repair result can be set according to experience. For example, the fault tolerance rate of two repair results is set to be 3% and 5% for the hand of the 'temple Buddha', and the fault tolerance rate of four repair results is set to be 3%, 5%, 7%, 9% and the like for the head of the 'temple Buddha'.

Taking the temple Buddha as an example, the generation process of the historical actual three-dimensional model data set and at least one historical restoration scheme corresponding to the historical actual three-dimensional model data is described.

First, basic information of the cultural relic, for example, which parts the cultural relic includes, the material of each part, original damage description, original three-dimensional model data, original data recording time and manufacturing process, the age of the cultural relic, etc. can be collected and stored, as shown in table 1:

TABLE 1

Then, the historical repair record of the cultural relic is recorded to form the information shown in table 2:

TABLE 2

Finally, the digital processing is carried out on the historical repair record of the cultural relic, and the method specifically comprises the following steps: 1) according to the damage description of the cultural relic component, three-dimensional model data under the damage state is simulated, namely: generating actual three-dimensional model data corresponding to the damage description; 2) converting each maintenance step included in the maintenance scheme into an image processing instruction for the model data; 3) the label repair scheme is an actual implementation or an alternative. In this embodiment, a history actual three-dimensional model data set formed by digitizing the history repair record in table 2 and history repair scenario information corresponding to the history actual three-dimensional model data are shown in table 3:

TABLE 3

Please refer to fig. 2, which is a specific flowchart of a repair scenario generation method according to an embodiment of the present application. In this embodiment, generating the repair plan of the component to be repaired may include the following specific steps:

step S201: and determining historical actual three-dimensional model data matched with the actual three-dimensional model data of the part to be repaired from the historical actual three-dimensional model data set.

The historical actual three-dimensional model data set comprises a plurality of historical actual three-dimensional model data of each preset part of the appointed cultural relic. As can be seen, in the historical actual three-dimensional model data set, a part of the model data matches with the actual three-dimensional model data of the part to be repaired, for example, the historical actual three-dimensional model data of the head of "temple buddha" matches with the actual three-dimensional model data of the head; the other part of the model data does not match with the actual three-dimensional model data of the part to be repaired, for example, the historical actual three-dimensional model data of the head of the temple Buddha does not match with the actual three-dimensional model data of the hand. Furthermore, a model data is determined from the matched historical actual three-dimensional model data. Therefore, it is first necessary to determine one historical actual three-dimensional model data that matches the actual three-dimensional model data of the part to be repaired from the historical actual three-dimensional model data set.

In specific implementation, the step S201 may include the following specific steps:

step S2011: and screening out historical actual three-dimensional model data of the part to be repaired of the specified cultural relic from the historical actual three-dimensional model data set.

Step S2013: and comparing the actual three-dimensional model data of the component to be repaired with the screened historical three-dimensional model data respectively, and obtaining the model similarity between the actual three-dimensional model of the component to be repaired and each screened historical three-dimensional model.

Step S2015: and selecting one historical actual three-dimensional model data from the screened historical actual three-dimensional model data according to the model similarity and a preset model selection rule.

When the step S2015 is specifically implemented, the following specific steps may be included: 1) taking the historical actual three-dimensional model data with the model similarity greater than or equal to a preset minimum model similarity threshold value as matched model data to form a matched model data set; 2) and selecting historical actual three-dimensional model data which accords with a preset model selection rule from the matched model data set.

The preset minimum model similarity threshold value is used as an index for measuring whether the two model data are matched, and may be set empirically, for example, the value may be set to 80%, that is, only the historical actual three-dimensional model data with the model similarity greater than or equal to 80% may be used as the model data matched with the actual three-dimensional model data of the component to be repaired.

The preset model selection rule may be to select the historical actual three-dimensional model data with the highest model similarity, or to select any one of the historical actual three-dimensional model data from the matched model data.

It should be noted that the above-mentioned embodiment of step S201 is only an optional embodiment, and in practical applications, other embodiments may also be adopted, for example, step S2011 may not be executed, and the actual three-dimensional model data of the component to be repaired may be respectively compared with each historical three-dimensional model data in the historical actual three-dimensional model data set, and the like; for another example, when the function of step S2015 is implemented, the minimum model similarity threshold may not be set, but only one piece of historical actual three-dimensional model data may be selected according to the model similarity and the preset model selection rule. These different embodiments are modifications of the embodiments, which do not depart from the core of the present application, and therefore all fall within the scope of the present application.

Step S202: and generating at least one repair scheme corresponding to the part to be repaired according to the at least one historical repair scheme corresponding to the determined historical actual three-dimensional model data.

Because the determined historical actual three-dimensional model data is matched with the actual three-dimensional model data of the component to be repaired, at least one repair scheme corresponding to the component to be repaired can be generated according to at least one historical repair scheme corresponding to the historical actual three-dimensional model data.

In specific implementation, all the repair schemes corresponding to the determined historical actual three-dimensional model data can be used as the repair schemes of the component to be repaired; or selecting a historical repair scheme reaching the repair result fault tolerance rate from all historical repair schemes corresponding to historical actual three-dimensional model data according to the repair result fault tolerance rate preset for the component to be repaired, and using the selected historical repair scheme as the repair scheme corresponding to the component to be repaired.

Now, a specific embodiment of step S103 is explained. It should be noted that the above specific implementation manner of step S103 is only an optional implementation manner, and in practical application, the function of step S103 may also be implemented in other manners to generate a repair scheme of the component to be repaired, for example, a training sample set for machine learning may be formed according to a pre-stored historical actual three-dimensional model data set and at least one historical repair scheme corresponding to the historical actual three-dimensional model data, the feature data of the training sample may include historical actual three-dimensional model data, a cultural relic category, a belonging component, a material, a year, a manufacturing process, a defect rate, repair time, and the like, the labeled data of the training sample may be set as the repair scheme, and in addition, the training sample corresponding to the actually implemented scheme may be used as a positive sample, and the training sample corresponding to the alternative scheme may be used as a negative sample; then, learning from the training sample set through a preset machine learning algorithm (such as an SVM model, a neural network model and the like) to obtain a repair scheme generation model; and finally, taking the actual three-dimensional model data, the cultural relic category, the affiliated part, the material, the age, the manufacturing process, the defect rate, the repair time and other characteristic data of the part to be repaired as the input of a repair scheme generation model, and automatically generating a repair scheme corresponding to the part to be repaired through the repair scheme generation model. Variations of the above-described forms, such as: the model data matching method, the machine learning model calculation method, and the like are modifications of the embodiments and do not depart from the core of the present application, and therefore, are all within the scope of the present application.

Step S105: and displaying the repaired three-dimensional model of each part to be repaired under each corresponding repairing scheme.

In the step, the repaired three-dimensional models of the parts to be repaired under the corresponding repair schemes are displayed for users to watch in a virtual reality mode, and the users can personally observe the repair effect picture with spatial sense through the virtual reality display equipment so as to evaluate and determine the actually adopted implementation scheme.

It should be noted that, the three-dimensional model after restoration displayed on the computer is directly viewed by human eyes, which cannot bring experience with spatial sense to the user. The method emphasizes that a user watches the repaired three-dimensional model with the sense of space through the virtual interactive display equipment. The virtual reality display device can be a VR head-mounted display device (VR glasses, VR helmet) and the like. Taking the VR head display as an example, the device utilizes the head-mounted display device to seal the human vision and hearing from the outside, and guides the user to generate a sense of being in a virtual environment. The display principle is that the left and right eye screens respectively display images of the left and right eyes, and the human eyes generate stereoscopic impression in the brain after acquiring the information with the difference.

Please refer to fig. 3, which is a flowchart illustrating a repaired three-dimensional model according to an embodiment of the cultural relic repairing method of the present application. In this embodiment, the post-repair three-dimensional model of the component to be repaired in the repair scheme through virtual reality may be displayed by adopting the following steps:

step S301: and generating the repaired three-dimensional model data of the part to be repaired according to the actual three-dimensional model data of the part to be repaired and the repair scheme.

It should be noted that the repair plan generated in step S103 may be a text-description repair plan or a repair plan in the form of an image processing instruction. If the repair solution generated at step S103 is a text-description repair solution, step S301 may include the steps of: 1) generating an image processing instruction sequence corresponding to the restoration scheme according to each restoration step included in the restoration scheme and a preset corresponding relation set between the restoration step and an image processing instruction; 2) and sequentially executing each image processing instruction on the actual three-dimensional model data to generate the repaired three-dimensional model data.

The preset corresponding relation set between the repairing steps and the image processing instructions comprises a plurality of corresponding relations between the repairing steps and the image processing instructions. The repairing step is a repairing step described in a text form, and the image processing instruction is an image processing instruction corresponding to the repairing step, for example, if the repairing step is to grind a damaged part flat, the corresponding image processing instruction may be an image processing instruction for converting a curved surface displayed at a corresponding position into a flat surface, and the like.

Step S302: and displaying the repaired three-dimensional model of the part to be repaired in the virtual reality under the repair scheme according to the repaired three-dimensional model data.

In addition, in order to create a cultural relic restoration scene with reality for a user, the following mode can be adopted when the restored three-dimensional model is displayed: and displaying the repaired three-dimensional model of the virtual reality in a preset scene graph.

The preset scene graph is a simulation graph of a real environment where the cultural relics are located during restoration, for example, the scene graph of the 'Temple Buddha' can be a scene image of an actual space (Temple hall) where the Buddha is located. Through the processing mode of displaying the repaired three-dimensional model of the virtual reality in the preset scene graph, the effect of repairing the cultural relics in the real scene by the repairing personnel can be achieved.

In order to enable the user to actively control and view which component to be repaired is under which repair scheme, the step S105 may include the following steps: 1) displaying information of each repair scheme corresponding to each component to be repaired, for example, displaying options of the component to be repaired and options of the repair scheme to a user; 2) and displaying a repaired three-dimensional model of the specific part to be repaired under the specific repair scheme according to the specific part to be repaired and the specific repair scheme specified by the user. By adopting the processing mode, the user experience can be improved.

When a user views information of each repair scheme corresponding to each component to be repaired through the virtual reality display device, the user can send an operation instruction (for example, a display instruction of a repaired three-dimensional model for a specific component to be repaired and a specific repair scheme) through the virtual reality input device, and can also send the operation instruction through other modes, for example, for operation behavior information sent by the user through a gesture, the gesture can be detected and recognized through the hand information capture device, so that the operation instruction of the gesture class can be obtained.

As a preferable scheme, the user can send the operation instruction through the virtual reality input device. A Virtual Reality input device is a device capable of mapping real world environment data to a Virtual world, that is, a device for inputting a user operation instruction to a VR (Virtual Reality) system. Unlike keyboards, mice, and gestures, virtual reality input devices emphasize immersion.

The virtual reality input device includes, but is not limited to, a glove, a handle, a double handle, a full body suit and other virtual reality input devices. With the development of virtual display technology, more and more virtual reality input devices are available for users. For example, a conventional handle incorporating an inertial sensor, a rumble motor, is used as a virtual reality input device, which is typically operated using conventional buttons/joysticks/touch pads and interacts with a rumble sensation.

The cultural relic restoration method can form the restoration scheme of the designated cultural relic according to the restoration scheme of each part to be restored designated by the user, and displays the restoration scheme of the designated cultural relic to the user, and further can display a three-dimensional model of the designated cultural relic after the restoration of the designated cultural relic under the restoration scheme of the designated cultural relic, so that the user can view the final restoration effect diagram of the selected scheme, and provide decision information of cultural relic restoration for the user.

Please refer to fig. 4, which is a flowchart illustrating a first method for repairing cultural relics according to an embodiment of the present application. As can be seen from fig. 4, the present embodiment includes the following steps: 1) acquiring original three-dimensional model data of each preset part of the appointed cultural relic by a CT scanning technology; 2) the method comprises the steps of appointing the defect rate and the repair result fault tolerance rate of each preset component of the cultural relic; 3) digitizing the traditional maintenance record to form a historical actual three-dimensional model data set and at least one historical repair scheme corresponding to the historical actual three-dimensional model data; 4) forming a training sample set according to the historical actual three-dimensional model data set and at least one historical restoration scheme corresponding to the historical actual three-dimensional model data, and learning from the training sample set through a machine learning algorithm to obtain a restoration scheme generation model; 5) acquiring actual three-dimensional model data of each preset part of the appointed cultural relic by a CT scanning technology; 6) calculating the defect rate of the actual three-dimensional model of each preset component; 7) judging whether the defect rate of the actual three-dimensional model of each preset component is larger than the defect rate threshold value of the preset component one by one; if the fault-tolerant rate of the preset component is equal to or higher than the preset fault-tolerant rate, generating a model according to a pre-generated repair scheme, and generating a repair scheme of the preset component under the preset fault-tolerant rate of the repair result; 8) displaying the repaired effect graphs corresponding to different repairing schemes; 9) and determining the actually adopted repair scheme according to the repair scheme specified by the user.
