DETAILED DESCRIPTION OF EMBODIMENTS

The following describes exemplary embodiments of the present disclosure with reference to the drawings, which include various details of the embodiments of the present disclosure to facilitate understanding, and should be regarded as merely exemplary. Therefore, those skilled in the art should recognize that various changes and modifications may be made to the embodiments described herein without departing from the scope and spirit of the present disclosure. Likewise, for clarity and conciseness, descriptions of well-known functions and structures are omitted in the following description.

Although the solution of automatic generation and then manual customization may eventually give a result of a virtual character, it is often difficult for the user to acquire a satisfactory virtual character. The reason is that through this traditional solution, it is impossible for the user to achieve an efficient customization of the virtual character.

Exemplarily, if a user is intended to generate a virtual character with a high nose, big eyes and a thin chin through the above-mentioned traditional method, there is a high possibility that the user is unable to find a photo of a real person with similar character features. Further, even if a photo of a real person with similar character features may be found the user needs to search for a facial feature, for example, in the bases of nose shape, eye shape, and face shape etc. one by one, in using the above-mentioned face pinching function. Generally, the App provides dozens of shapes for a single facial feature for the user to choose. Therefore, it takes tens or even dozens of minutes to select the shape of each facial feature. Many users may not have the patience to spend time to choose satisfactory facial features.

In addition, this traditional customization solution of the virtual character is not convenient for users to use and may even cause great frustration and experience damage to users.

An intelligent generation solution of a virtual character based on language description proposed in the present disclosure may implement the efficient customization of the virtual character. The disclosure will be described in detail below in conjunction with specific embodiments.

A system architecture, in which a method and apparatus for generating a virtual character according to the embodiments of the present disclosure may be applied, is introduced as follows.

FIG. 1A exemplarily illustrates a system architecture in which a method and apparatus for generating a virtual character according to the embodiments of the present disclosure may be applied. It should be noted that FIG. 1A is just an example of the system architecture in which the embodiments of the present disclosure may be applied to help those skilled in the art to understand the technical content of the present disclosure, but it does not mean that the embodiments of the present disclosure may not be used in other environments or scenes.

As shown in FIG. 1A, the system architecture 100 may include: a terminal device 101. It should be noted that the terminal device 101 may be a client or a server, which is not limited in the present disclosure.

Specifically, an initial virtual character may be generated as a reference virtual character through the terminal device 101 or other apparatus. If a user wants to customize a virtual character as personally desired, such as a virtual character with “high nose, big eyes, thin chin”, the user may describe the desired virtual character through language. After the terminal device 101 obtains the language description generated by the user, a respective semantic feature may be extracted based on the language description, and then the desired virtual character is generated based on the extracted semantic feature.

In the embodiments of the present disclosure, according to the language description generated the user, the terminal device 101 may accurately recognize a semantic feature information of the virtual character required by the user, and then generate the virtual character intelligently. On the one hand, the solution may improve the efficiency of producing a customized virtual character and give user a more convenient experience; on the other hand, it may also improve the accuracy of customization of the virtual character and provide a satisfactory virtual character to user.

It should be understood that the number of terminal devices in FIG. 1A is illustrative. Any number of terminal devices may be included as desired in practice.

A scenario in which the method and apparatus for generating a virtual character according to the embodiments of the present disclosure may be applied are introduced as follows.

It should be understood that at present, the offline consumption guidance is mainly based on bloggers visiting stores and sharing their experiences. If consumers do not actively read the content shared by bloggers, it is difficult to achieve an effective recommendation.

It should also be understood that the customized virtual character usually has similarity with real person, different virtual characters are distinguished from each other, and the cartoon appearance of the virtual character may also have an enhanced affinity. All this may help improve the subjective recognition of the virtual character by the user. In this way, a virtual character may be created, a human-computer interaction may be achieved based on the virtual character, and a consumption recommendation and a consumption accompanying may be provided in proper time by using the virtual character during the process of human-computer interaction based on the virtual character. In this way, the conversion rate of consumption recommendation may effectively increase while the user experience may be improved.

Exemplarily, in the embodiments of the present disclosure, a guidance of offline consumption may be provided to the user in the home scene based on the virtual character, and a consumption accompanying may be provided to the user in the offline consumption scene based on the virtual character.

As shown in FIG. 1B, the user may create a virtual character specific to the user through a mobile client and upload the virtual character to a cloud. Then the virtual character is sent to a smart device associated with the user and an interactive device (such as mall interactive device, supermarket interactive device, restaurant interactive device, etc.) deployed in public places such as supermarket visited by user, so that the user may use it during human-computer interaction.

It should be noted that, in the embodiments of the present disclosure, the smart device includes an IoT device with a display, such as a refrigerator, a television, a smart mirror, a smart glass and so on. After the virtual character is sent to the IOT device, the IOT device may be triggered to display the virtual character in real time, so that the virtual character vividly communicates with the user in a functional or meaningless dialogue as a front-end carrier of an intelligent voice dialogue system. In the process of dialogue and communication, the virtual character may provide a consumption recommendation to user offline in proper time according to a marketing recommendation instruction sent by the cloud.

In addition, in the embodiments of the present disclosure, the mall interactive device also includes an electronic apparatus having a capability of interfacing with a user, which contains a display and is deployed in the mall. Exemplarily, when the user visits the mall, the identification of the user may be determined through face recognition technology, and the cloud is notified to send the respective virtual character. For example, when user A tries on clothes in a certain brand clothing store, a virtual character specific to user A may be sent from the cloud, and the virtual character specific to user A is displayed on the edge of the fitting mirror near user A to interact with the user, such as recommend the user to try clothes. For another example, when user B eats single-person hot pot in a hot pot restaurant, a small display may be set up next to the hot pot of user B, and a virtual character specific to user B may be displayed on the small display to perform meaningless interaction with user B or play a game with user B.

In an embodiment of the present disclosure, the user may upload a photo, and then the virtual character generation App automatically generates a primary virtual character based on the portrait in the photo. Then the user may manually pinch the face of the primary virtual character by using the face pinching function in the App, in order to generate a virtual character specific to the user.

In another embodiment of the present disclosure, the user may also generate a virtual character specific to the user through the intelligent generation solution of virtual character based on language description.

In another embodiment of the present disclosure, in addition to receiving the virtual character created by the mobile client and sending the virtual character to the smart device associated with the user and the interactive device deployed in a public place such as a supermarket visited by the user, the cloud may also analyze big data of user(s) and provide a marketing strategy at proper time, in order to achieve a marketing task by using the virtual character displayed on the smart home device. For example, it rains on a certain day, the weather is very cold, and the user has not eaten hot pot for a long time, then the virtual character may affectionately recommend a hot pot dining place to the user.

According to the embodiments of the present disclosure, providing a service of accompanying consumption recommendation by using a virtual character similar to a real person may cause the user to feel acceptance. Through the recommendation by the virtual character, the user consumption may also be guided to offline scene. And in real consumption scenes, the virtual character specific to the user may also accompany the user, to recommend products to user, accompany the user to eat and chat. In this way, online services and offline services may be connected.

In the embodiments of the present disclosure, by using the virtual character specific to the user, it is easier to obtain the trust and acceptance of the user in the development companionship by the virtual character, and thus it is easier to achieve the consumption recommendation by the virtual character.

As an optional embodiment, the method further includes the following operations.

A consumption data is acquired.

Based on the consumption data, a marketing strategy for the user is generated in order to be sent to the smart device.

Exemplarily, the cloud may acquire the consumption data uploaded by the interactive device and the cashier device installed in a public place such as a supermarket, and a big data analysis is performed based on the acquired consumption data, thereby generating the marketing strategy for an individual user or a certain group of users. The generated marketing strategy is sent to the smart device associated with the specific user or the specific category of users, so that the virtual character displayed on the smart device may provide a consumption recommendation to the user(s) at proper time. It should be noted that in the embodiments the consumption data is not consumption data for a specific user and does not reflect the personal information of the specific user. In the embodiments, the consumption data may be obtained from public dataset.

According to the embodiments of the present disclosure, the consumption habits may be learned from the consumption data, and then the marketing strategy that conforms to the consumption habits of the user may be formulated, thereby implementing precision marketing.

In the process that the user consumes in the leisure and entertainment venue, the virtual character is controlled to communicate and interact with the user to accompany the user in leisure and entertainment.

Exemplarily, for example, when user A tries on clothes in a certain brand clothing store, the virtual character specific to user A may be sent from the cloud, and the virtual character specific to user A is displayed on the edge of the fitting mirror near user A, so as to interact with the user, such as recommending the user to try on clothes. For another example, when user B is having a single-person hot pot in a hot pot restaurant, a small display may be set up next to user B's hot pot, and the virtual character specific to user B may be displayed on the small display, so as to have meaningless interaction or game with user B.

According to the embodiments of the present disclosure, the virtual character similar to the real person in some extant is used to provide the accompanying consumption service, which may make user feel acceptance. And in the real consumption scene, the virtual character specific to the user accompanies the user, which may help the user to purchase a satisfactory product and accompany the user to have dinner, to chat and so on. In this way, online service and offline service may be connected.

As an optional embodiment, the method may further include the following operations.

A consumption data is acquired.

The consumption data is sent to the cloud so that the cloud may generate a marketing strategy for user based on the consumption data.

Exemplarily, the interactive device and a cashier device in a public place such as a mall and a supermarket may collect the consumption data and upload the consumption data to the cloud, and then the cloud performs big data analysis based on the acquired consumption data, thereby generating a marketing strategy for an individual user or a certain group of users, so that the cloud will send the marketing strategy to a respective smart home device, and the virtual character displayed on the smart home device will provide a consumption recommendation to the user(s) at proper time. It should be noted that in the embodiments the consumption data is not consumption data for a specific user and does not reflect the personal information of the specific user. In the embodiments, the consumption data may be obtained from public dataset.

As an optional embodiment, the method may further include the following operations.

In response to the user entering a specific place, a face of user is recognized to determine the identification of the user.

A virtual character specific to the user is acquired based on the identification of the user.

Wherein displaying the virtual character on a specific interactive device in the specific place may include: displaying the virtual character specific to the user on the specific interactive device in the specific place.

It should also be understood that the customized virtual character usually has similarity with real person, different virtual characters are distinguished from each other, and the cartoon appearance of the virtual character may also have an enhanced affinity. All this may help to improve the subjective recognition of the virtual character of the user. In this way, the virtual character may be created, the human-computer interaction may be implemented based on the virtual character, and a consumption recommendation and a consumption accompany may be provided by the virtual character during the process of human-computer interaction based on the virtual character.

According to the embodiments of the present disclosure, the present disclosure also provides a method for generating a virtual character.

FIG. 2 exemplarily illustrates a flowchart of a method for generating a virtual character according to the embodiments of the present disclosure.

As shown in FIG. 2, the method 200 may include: operations S210 to S230.

In operation S210, a language description generated by a user for a target virtual character is acquired.

In operation S220, a respective semantic feature is extracted based on the language description.

In operation S230, the target virtual character is generated based on the semantic feature.

It should be noted that, in operation S210, the language description may include the language description in the form of voice or text, which is not limited in the embodiments of the present disclosure. Wherein, for the language description in the form of voice, in operation S210, a semantic requirement of user for the target virtual character may be captured through the automatic voice recognition ASR technology.

Exemplarily, if the user wants to create a target virtual character with “high nose, big eyes, thin chin”, the user may input the following language description “high nose, big eyes, thin chin” for the target virtual character. Thus, through the above operations provided by the method 200, the language description “high nose bridge, big eyes, thin chin” may be acquired, and the semantic feature such as “high nose bridge, big eyes, thin chin” may be extracted. In addition, in the embodiments of the present disclosure, a virtual character may also be arbitrarily created in advance as a reference virtual character. Then every time the respective semantic feature is extracted for the target virtual character, the reference virtual character may be deformed based on the extracted semantic feature, so as to finally obtain the target virtual character desired by the user.

According to the embodiments of the present disclosure, as long as the user provides a semantic description of the target virtual character, the existing reference virtual character may be semantically modified as required by the user semantically, without the need for the user to perform additional manual customization operation, so as to implement the customization of the virtual character with high efficiency and high accuracy. In this way, user experience and acceptance of customized virtual character may also be improved.

In addition, the embodiments of the present disclosure provide convenience to the user, because the user only needs to give the semantic description of the target virtual character and it is not necessary for the user to perform additional manual customization operations.

As an optional embodiment, generating the target virtual character based on the semantic feature may include the following operations.

The reference virtual character is acquired.

Based on the semantic feature extracted from the semantic description generated by the user, the reference virtual character is deformed to generate the target virtual character.

In the embodiments of the present disclosure, a virtual character may be arbitrarily created as the reference virtual character in advance, and the reference virtual character is directly acquired in the process of customization of the target virtual character, and the semantic feature extracted from the semantic description generated by the user are used to drive the reference virtual character to deform, so as to obtain the respective target virtual character.

Exemplarily, a virtual character model of the reference virtual character may be created, and then a skeleton tree is created for the virtual character model, and then each skeleton node of the skeleton tree is skinned, so that the skeleton node and a respective skinned mesh node are associated to obtain the respective reference virtual character.

In addition, the deforming the reference virtual character based on the semantic feature extracted from the semantic description generated by the user may include: a virtual character slider (hereinafter referred to as a slider) with the semantic feature is acquired, and then the slider is used to drive the skeleton node of the reference virtual character to move, thereby driving the skinned mesh node of the reference virtual character to move accordingly. Finally, the target virtual character that the user wants is obtained, that is, the desired virtual character.

Exemplarily, if the user wants to create a target virtual character of “high nose, big eyes, thin chin”, the following semantic feature “high nose, big eyes, thin chin” may be extracted based on the semantic description, and then three sliders of “high nose slider”, “big eyes slider” and “thin chin slider” are acquired, and the three sliders are used to drive the pre-created reference virtual character to deform, so that finally the desired virtual character complying with the features of “high nose, big eyes, and thin chin” is obtained.

According to the embodiments of the present disclosure, the customized virtual character is customized by using artificial intelligence algorithms, on the one hand, the production efficiency of the customized virtual character may be improved, and more convenient user experience may be provided; on the other hand, the accuracy of customization of virtual character may be improved.

As an optional embodiment, the deforming the pre-created reference virtual character based on the semantic feature extracted from the semantic description generated by the user to generate the target virtual character may include the following operations.

The extracted semantic feature is converted into a professional semantic feature.

The reference virtual character is deformed based on the professional semantic feature obtained by the conversion.

It should be understood that in practice, different users may have different language descriptions of the same or similar characters. For example, for “thin chin”, some users may describe it as “cone face”, some users may describe it as “pointed face”, and some users may even have other descriptions. In addition, in practical applications, it is difficult for users to give descriptions of the shapes of “cheekbones” and “chin”. More generally, users will choose more general descriptions to portray a feeling about the virtual character, such as “like a little girl”, “like a grandma”, “sunshine”, “handsome” and so on.

Therefore, the embodiments of the present disclosure propose to first convert the semantic feature extracted from the semantic description generated by the user uniformly into the professional semantic feature, and then the reference virtual character is deformed based on the converted semantic feature to obtain the final target virtual character.

Exemplarily, the semantic feature (that is, the general semantic feature given by the user) extracted by a semantic converter may be converted into the professional semantic feature. The professional semantic feature may be a semantic feature contained in a semantic description in anatomy and biology. Wherein, in the embodiments of the present disclosure, the semantic converter may be implemented by collecting a large amount of data and regression training in deep learning.

As shown in FIG. 3, in the embodiment of the present disclosure, taking the face shape as an example, the semantic keyword “pointed face” extracted from the language description generated by user may be converted into the following professional semantic features “low cheekbones” and “narrow chin”; the semantic keyword “square face” extracted from the language description generated by user may be converted into the following professional semantic features “high cheekbones” and “wide chin”; the semantic keyword “cute face” extracted from the language description generated by user may be converted into the following professional semantic features “big eyes” and “round face”.

In addition, in the embodiments of the present disclosure, since the general semantic description generated by the user may be converted into the respective professional semantic description, a slider that drives the reference virtual character to deform may be created based on the professional semantics. For example, a high cheekbone slider, a low cheekbone slider, a narrow chin slider, a big eyes slider, a round face slider may be created. If the user enters “pointed face”, it may be converted into two professional semantics, “low cheekbones” and “narrow chin”. Then the two sliders “low cheekbone slider” and “narrow chin slider” are directly used to drive the reference virtual character to deform, and finally the desired virtual character of “pointed face” is implemented.

According to the embodiments of the present disclosure, even if the user inputs the general language description in practical applications, the respective professional language description may be obtained through semantic conversion. Then the reference virtual character is precisely deformed, so as to finally obtain the virtual character desired by the user.

As an optional embodiment, the deforming the reference virtual character based on professional semantic feature may include the following operations.

At least one slider is determined based on the professional semantic features, and each slider is associated with a specified semantic tag.

A plurality of respective skeleton nodes of the skeleton tree used for supporting the reference virtual character are driven to move based on the at least one slider.

Skinned mesh nodes associated with the plurality of respective skeleton nodes are driven to move based on the movement of the plurality of respective skeleton nodes.

Specifically, in the embodiments of the present disclosure, after the general semantic feature described by the user is converted into professional semantic feature, at least one keyword contained in the professional semantic feature obtained by the conversion may be extracted. Then at least one semantic tag containing the at least one keyword is found, and a slider associated with each semantic tag of the at least one semantic tag is found. Finally, the found slider is used to move the plurality of respective skeleton nodes of the skeleton tree used to support the reference virtual character, and then the skinned mesh nodes associated with the plurality of respective skeleton nodes are driven to move based on the movement of the plurality of respective skeleton nodes.

Exemplarily, FIGS. 4A to 4D represent “wide face slider”, “narrow face slider”, “long face slider” and “short face slider” in sequence. FIG. 5 illustrates the reference virtual character in which the binding of the skeleton and the skin is achieved. Exemplarily, in the case that the general language description input by the user or the converted professional language description contains the “wide face” feature, the “wide face slider” as shown in FIG. 4A may be directly used to drive the reference virtual character to deform as shown in FIG. 5, thereby obtaining the target virtual character having the wide face feature.

According to the embodiments of the present disclosure, the slider with semantic information is used to deform the reference virtual character, which may improve the output efficiency of the target virtual character while improving the accuracy of the obtained target virtual character.

It should be noted that, in order to achieve deformation of the virtual character in less cost, 3D model designers usually design a skeleton tree for the face model, and a weight influence relationship is established between each skinned mesh node of the face mesh (skinned mesh) and each skeleton node of the skeleton tree. Afterwards, the deformation of each skeleton node may be transmitted to each skinned mesh node of the face skinned mesh by controlling the rotation, translation, and scaling of each skeleton node of the skeleton tree, and the deformation of each skinned mesh node may be implemented.

However, the skeleton tree is designed for the geometric structure of the human face, and most skeleton nodes do not have actual semantic meanings such as wide face and high nose. This makes the designer need to design a slider after completing the skinned mesh setting work, and then the slider is used to implement batch operations on each skeleton node of the skeleton tree, and semantic-level performance capability is finally achieved. For example, by using the wide face slider, eight skeleton nodes may be adjusted in batches, including left and right temples, left and right cheekbones, left and right mandibular angles, and left and right foreheads.

However, the linkage design of a large number of skeletons not only requires the designer's manpower cost, but also the complicated relationship between the skeletons often leads to the poor expressiveness of the designed semantic-level slider.

Therefore, the embodiments of the present disclosure propose an improved design scheme for a virtual character slider. After the designer completes the skinned mesh design, that is, after the designer completes the binding of skeleton and skinned mesh (also known as association of skeleton and skinned mesh), the designer may just focus on designing the shape model respective to the semantics without continuing to design the respective virtual character slider with semantic information. This is because the reference virtual character and the respective shape module designed by the designer by associating the skeleton and the skinned mesh are directly inputted into the “slider design system”, a skeleton linkage coefficient with semantic information (that is, slider information) is automatically outputted, which may ensure the high-quality design of the slider.

The present disclosure also provides a method for processing a slider for a virtual character.

As shown in FIG. 6A, the method for processing a slider for a virtual character may include: operations S610 to S640.

In operation S610, a shape model associated with a target semantic tag is acquired. Where the target semantic tag is identical to a specified semantic tag associated with a slider.

In operation S620, a skeleton and skinning information of a reference virtual character is acquired.

In operation S630, the shape model is fitted based on the skeleton and skinning information to obtain a skeleton linkage coefficient.

In operation S640, a slider associated with the target semantic tag is generated based on the skeleton linkage coefficient.

wherein the slider is used to drive the reference virtual character to obtain a target virtual character complying with a target semantic feature contained in the target semantic tag.

Exemplarily, taking the face shape as an example, the “wide face model” (associated with the wide face tag) and the reference virtual character that has completed the binding of skeleton and skinned mesh are inputted into a skeleton coefficient fitting solver, and the “wide face skeleton linkage coefficient” (ie “wide face slider information”) may be outputted; the “narrow face model” (associated with the narrow face tag) and the reference virtual character that has completed the binding of skeleton and skinned mesh are inputted into the skeleton coefficient fitting solver, and the “narrow face skeleton linkage coefficient” (ie “narrow face slider information”) may be outputted; the “long face model” (associated with the long face tag) and the reference virtual character that has completed the binding of skeleton and skinned mesh are inputted into the skeleton coefficient fitting solver, the “long face skeleton linkage coefficient” (ie “long face slider information”) may be outputted; the “short face model” (associated with the short face tag) and the reference virtual character that has completed the binding of skeleton and skinned mesh are inputted into the skeleton coefficient fitting solver, the “short face skeleton linkage coefficient” (ie, “short face slider information”) may be outputted. Wherein the skeleton coefficient fitting solver is used to fit each shape model based on the skeleton and skinning information of the reference virtual character, so as to obtain the respective skeleton linkage coefficient. After obtaining the respective skeleton linkage coefficient, associate it with the respective semantic tag, and the slider of respective semantic may be obtained. For example, the “wide face slider information” is associated with the “wide face tag”, the “wide face slider” may be obtained.

It should be noted that in another embodiment of the present disclosure, the skeleton and skinning information of the reference virtual character and a plurality of shape models (each shape model corresponds to a different semantic tag) may also be transmitted into the skeleton coefficient fitting solver, so as to automatically acquire a plurality of sliders respective to each semantic tag, and the efficient production of sliders is ensured.

Exemplarily, as shown in FIG. 6B, taking the face shape as an example, the “wide face model”, “narrow face model”, “long face model” and “short face model” and a reference virtual character in which binding of skeleton and skinned mesh is achieved are inputted into a skeleton coefficient fitting solver, thereby automatically outputting “wide face slider”, “narrow face slider”, “long face slider” and “short face slider”.

It should be understood that the semantic slider design is implemented by linkage of a plurality of skeleton nodes under the design of designer. Specifically, the skeleton generally may transform in three freedoms, i.e. translation, rotation, and scale. The designer will set weight for the skinned mesh node affected by the skeleton. In actual deformation, the skinned mesh node performs weighted deformation according to the skeleton transformation data and the respective weight set.

However, a slider may usually affect a plurality of skeleton nodes. The designer designs the influence relationship of the slider on the plurality of skeleton nodes, so that the slider has respective semantics, such as “low cheekbones” slider, “pointed chin” slider, etc., but achieving the semantic features relies on the linkage of the plurality of skeleton nodes to achieve.

With the embodiments of the present disclosure, the designer may just focus on the design of the shape model associated with the semantic tag, and then the shape model may be fitted by the skeleton coefficient fitting solver to implement the slider design. That is, the embodiments of the present disclosure integrate the skeleton coefficient fitting ability and redefine the generation method and production process of the slider, which comprehensively reduces the burden of the designer on the slider design. The designer gets rid of the cumbersome multi-skeleton linkage design and may focus more on the design of the semantically respective shape model. Therefore, the designer may be liberated from the complex multi-skeleton node linkage design, thereby improving the production efficiency of digital assets.

As an optional embodiment, the reference virtual character may be created through the following operations.

A respective skeleton tree is created for the reference virtual character,

A skeleton is associated with a skinned mesh based on the skeleton tree to obtain the reference virtual character.

Exemplarily, taking the face model as an example, the designer may design a skeleton tree for face model, and the face skinned mesh (skinned mesh) is associated with each skeleton node of the skeleton tree to implement the binding of face skinned mesh and each skeleton node, in order to obtain the respective reference virtual character.

As an optional embodiment, fitting the shape model based on the skeleton and skinning information to obtain the respective skeleton linkage coefficient may include the following operations.

Based on the skeleton and skinning information, the shape model is iteratively solved from a root skeleton node to a leaf skeleton node of the skeleton tree one by one to obtain the skeleton linkage coefficient.

Wherein the skeleton tree is created for the reference virtual character.

According to the embodiments of the present disclosure, the skeleton linkage coefficient may be obtained through a bottom-up iterative algorithm, so the fitting calculation efficiency is higher.

As an optional embodiment, the iterative solution of the shape model from the root skeleton node to the leaf skeleton node of the skeleton tree one by one may include: fitting for a rotation coefficient, a translation coefficient and a scaling coefficient of each skeleton node by applying the least square method from the root skeleton node of the skeleton tree level-by-level, until the rotation coefficients, the translation coefficients and the scaling coefficients of all the leaf skeleton nodes of the skeleton tree are solved.

It should be noted that, in the embodiments of the present disclosure, the skeleton coefficient fitting solver may adopt a bottom-up solving strategy. That is, the least square method is applied from the root node of the skeleton tree level-by-level to fit for the rotation coefficient, the translation coefficient and the scaling coefficient of each skeleton node of the shape model respectively, until all the leaf nodes of the skeleton tree are solved.

As an optional embodiment, fitting the shape model based on the skeleton and skinning information to obtain the respective skeleton linkage coefficient may include: based on the skeleton and skinning information, the shape model is iteratively solved from a root skeleton node to a leaf skeleton node of the skeleton tree one by one in a plurality of rounds to obtain the skeleton linkage coefficient. Wherein the skeleton tree is created for the reference virtual character.

According to the embodiments of the present disclosure, the skeleton linkage coefficient may be obtained by performing a bottom-up iterative algorithm in a plurality of rounds, that is, the fitting coefficients of the skeleton tree node(s) at each level are solved level-by-level, so as to obtain a more accurate fitting result.

In addition, the embodiments of the present disclosure may also support other types of skeleton coefficient fitting calculation algorithms, and the embodiments of the present disclosure are not limited herein.

The embodiments of the present disclosure implement the intelligent generation of the virtual character slider through the integration of related algorithms and the semantic definition of the input and output of the slider intelligent generation system.

As an optional embodiment, fitting the shape model based on the skeleton and skinning information to obtain the respective skeleton linkage coefficient may include: the skeleton and skinning information and the shape model are inputted into the preset skeleton coefficient fitting solver, so that the shape model is fitted by the skeleton coefficient fitting solver, so as to obtain the skeleton linkage coefficient.

According to the embodiments of the present disclosure, the designer may just focus on the design of the shape model associated with the semantic tag, and then the shape model may be fitted by the skeletal coefficient fitting solver to implement the slider design.

As an optional embodiment, the method may further include: the skeleton and skinning information and the generated slider are stored in the same file.

Exemplarily, after the “wide face slider” is obtained, if the “wide face slider” and the “reference virtual character” are stored in the same file, the “wide face slider” may automatically drive the “reference virtual character” to generate a “wide face virtual character” after the “wide face virtual character” startup process is triggered.

According to the embodiments of the present disclosure, the virtual character slider and the reference virtual character are stored in the same file, and when the virtual character is started, the reference virtual character may be directly driven by the slider to quickly output a target virtual character described by the user.

As an optional embodiment, generating the target virtual character based on semantic feature may include the following operations.

At least one semantic tag is determined cased on the semantic feature.

The respective at least one accessory model and/or at least one decoration model is determined based on the semantic tag.

On the basis of the virtual character obtained by deforming the reference virtual character, at least one accessory model and/or at least one decoration model is added, to obtain the target virtual character.

Exemplarily, if the user wants to create a target virtual character with “high nose, big eyes, thin chin, long hair, student clothes, white sneakers”, the following semantic features “high nose, big eyes, thin chin” may be extracted first based on the semantic description. Then three sliders are acquired: “high nose slider”, “big eye slider” and “slim chin slider”, and the 3 sliders are used to deform the pre-created reference virtual character, so as to obtain a virtual character that meets the features of “high nose, big eyes and thin chin”. At the same time, the following semantic features “long hair, student clothes, white sneakers” may also be extracted based on the semantic description, accessory models such as “long hair model” are acquired from the digital asset library of hairstyle accessory, and decoration models such as “girl student clothing model” and “white sneaker model” are acquired from the clothing digital asset library including clothing, shoes, hats, etc. Finally, the “long hair model”, “girl school wear model” and “white sneakers model” are added to the previously created virtual character with the features of “high nose, big eyes and thin chin”, and the finally output virtual character is the target virtual character that the user wants.

It should be understood that in the embodiments of the present disclosure, the digital asset library of hairstyles and beard accessories may include various types of men's beard models, various types of men's hairstyle models, and various types of women's hairstyle models. It should also be understood that the clothing digital asset library may contain various male and female glasses, clothes, shoes, watches, gloves, headwear, scarves and other accessory models. Each model in the digital asset library is associated with a unique semantic tag, so that the respective model may be automatically acquired based on the semantic tag.

Exemplarily, a different semantic tag may be defined for each model in the digital asset library, such as white sneaker, high heels, little red skirt, student wear, professional formal wear and so on. According to the semantic tags such as hairstyle and clothing output by the semantic converter, the respective model may be selected from the digital asset library and added to the generated virtual character.

As shown in FIG. 7, the customization process of a customized virtual character may be as follows: user enters a voice description; a speech recognition is automatically performed through ASR technology; a keyword of the voice description is extracted; the extracted keyword is converted through a semantic converter; a slider semantic tag associated with a slider is acquired from the converted keyword; a slider that drives the skeleton deformation is acquired based on the slider semantic tag; a respective skeleton deformation coefficient is acquired based on the slider; a linkage deformation of skinned mesh is driven based on the skeleton deformation coefficient; a model semantic tag associated with hairstyle, clothing, etc. is acquired from the converted keyword; a respective model is acquired from a digital asset library based on the model semantic tag; the acquired model is added to a virtual character generated by the linkage deformation of the skinned mesh to obtain a final target virtual character.

According to the embodiments of the present disclosure, the target virtual character may be beautified and enriched through accessory, so as to obtain a target virtual character satisfying the user.
