[0023] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0024] Figure 1 The flowchart of the virtual network space sharing method is as follows. In an embodiment of the present invention, a virtual network space sharing method is provided, and the method includes: Step S100: Send a mapping model creation request to the user, receive information acquisition authority feedback from the user, obtain basic information and adjustment information of the user based on the information acquisition authority, and create a mapping model corresponding to the user; The mapping model is a virtual character corresponding to the user. Before creating the mapping model, it is necessary to send a mapping model creation request to the user and receive the information acquisition authority fed back by the user. After receiving the information acquisition authority fed back by the user, the user's basic information and adjustment information are obtained to create a mapping model corresponding to the user; the basic information is used to represent the user's objective information, and the adjustment information is used to represent the user's active correction information.

[0025] Step S200: receiving space setting information input by a user, and determining a virtual network space according to the space setting information; Receive space setting information input by the user, the space setting information indicates in which space the user wants to interact, which can be some simulated outdoor space or some simulated indoor space. After receiving the space setting information input by the user, the execution subject of this method determines the virtual network space according to the space setting information.

[0026] Step S300: inserting the mapping model into the virtual network space, and sending the virtual network space containing the mapping model to all users; After the virtual network space is determined, the virtual network space is the interactive scene. The mapping model corresponds to each user one by one. The mapping model is inserted into the virtual network space, and then the browsing screen of each user is determined based on the virtual network space containing the mapping model and sent to the corresponding user.

[0027] Step S400: Under the premise of having the information acquisition authority of user feedback, the current information of the user is acquired in real time, and the virtual network space containing the mapping model is updated according to the current information; In step S100, the information acquisition authority has been obtained, and the user's current information is obtained in real time based on the information acquisition authority, the mapping model is updated, and the virtual network space containing the mapping model is also updated; accordingly, the virtual screen received by each user will also change accordingly; wherein, the current information includes the user's visual information, command information and audio information; the visual information is used to adjust the display state of the mapping model, the command information is used to adjust the position and orientation of the mapping model, and the audio information user introduces the information source at the mapping model.

[0028] Figure 2 The first sub-flow diagram of the virtual network space sharing method includes the steps of sending a mapping model creation request to a user, receiving information acquisition authority feedback from the user, acquiring basic information and adjustment information of the user based on the information acquisition authority, and creating a mapping model corresponding to the user. Step S101: Send a mapping model creation request to the user and receive information acquisition authority feedback from the user; Step S102: obtaining basic information of the user based on the information acquisition authority; the basic information includes age, height and weight; Step S103: determining a body model according to the basic information, obtaining visual information of the user based on the information acquisition authority, and determining a facial model in the body model according to the visual information; Step S104: displaying the body model including the face model, receiving adjustment information input by the user, and adjusting the body model including the face model; Step S105: inserting the user's unique label into the adjusted model as a mapping model corresponding to the user.

[0029] In an example of the technical solution of the present invention, a mapping model creation request is sent to a user, information acquisition authority feedback from the user is received, and the user's age, height and weight are obtained based on the information acquisition authority to create a body model; it should be noted that when obtaining basic information in the present application, gender is not a mandatory option, and the user can enter gender. At this time, the execution subject of this method will add corresponding features. If no gender is entered, it is defaulted to no gender, and only a basic model is created by height, weight and age, so that the final mapping model is more similar; after determining the body model based on the basic information, the user's visual information is obtained based on the information acquisition authority, and the facial model in the body model is determined based on the visual information. This process involves facial recognition. During the process, a permission confirmation window can be popped up to receive the permission granted by the user more clearly; after the facial model is inserted into the body model, the body model containing the facial model is displayed, and the adjustment information entered by the user is received, and the body model containing the facial model is adjusted.

[0030] The unique label of the user is inserted into the adjusted model as a mapping model corresponding to the user. In layman's terms, the execution subject of this method generates a cartoon model corresponding to the user one by one.

[0031] Furthermore, the steps of determining the body model according to the basic information, acquiring the user's visual information based on the information acquisition authority, and determining the facial model in the body model according to the visual information include: Query the body model in the preset model library according to the basic information; Obtain the user's visual information based on the information acquisition authority, and convert the visual information based on the AI ​​module to obtain an AI image; Determine the facial model in the body model based on the AI ​​image.

[0032] The above content limits the process of determining the facial model. The body model is queried in the preset model library based on the basic information, the user's visual information is obtained based on the information acquisition authority, and the visual information is converted based on the AI ​​module to obtain an AI image. The AI ​​image ensures the degree of facial restoration and has aesthetic appeal, which is more acceptable to users. The facial model in the body model is determined based on the AI ​​image.

[0033] Figure 3 This is a second sub-flow diagram of the virtual network space sharing method, wherein the step of receiving space setting information input by a user and determining the virtual network space according to the space setting information comprises: Step S201: receiving a user's shared code, verifying the shared code, and establishing a user group; Step S202: receiving space demand information uploaded by each person in the user group, and matching the virtual network space; the space demand information is a keyword set; the correspondence between the keywords and the virtual network space is determined by a preset table; Step S203: sending the matched virtual network space to each user in the user group, and receiving confirmation information fed back by the user; Step S204: After receiving confirmation information from each user, all matched virtual network spaces are counted and merged as the final virtual network space.

[0034] The technical solution of the present invention is aimed at sharing needs, receiving the user's sharing code, which is the password, verifying the sharing code, establishing a user group, each user in the user group is an information sharing party, receiving the space demand information uploaded by each person in the user group, this process is to obtain the needs of each user, the needs of each user may be different, for each demand, match the corresponding virtual network space, the space demand information is a set of keywords; the correspondence between the keywords and the virtual network space is determined by a preset table; sending the matched multiple virtual network spaces to each user in the user group, this process is a notification process, informing each user of the needs of other users, receiving confirmation information from the user feedback, if not confirmed, it means that a current demand is difficult to be accepted by a certain user, at this time, the users will communicate with each other, and after the communication, the virtual network space will be determined.

[0035] Figure 4 The third sub-flow diagram of the virtual network space sharing method, wherein the steps of inserting the mapping model into the virtual network space and sending the virtual network space containing the mapping model to all users include: Step S301: determining an initial position and an initial orientation of a mapping model based on a user's request, and inserting the mapping model into a virtual network space based on the initial position; Step S302: determining a display viewing angle according to an initial position and an initial orientation of each mapping model; Step S303: obtaining a front view of the virtual network space based on the display viewing angle; Step S304: Send the front view to the user corresponding to the mapping model.

[0036] Receive a request sent by a user, determine the initial position and initial orientation of a mapping model corresponding to the user in the virtual network space, insert the mapping model into the virtual network space based on the initial position, determine a display viewing angle according to the initial position and initial orientation of each mapping model, obtain a front view of the virtual network space based on the display viewing angle, and send the front view to the user corresponding to the mapping model.

[0038] In an example of the technical solution of the present invention, under the premise of having the authority to obtain information from user feedback, the adjustment instructions input by the user are received in real time, the adjustment instructions include position adjustment information and orientation adjustment information, which means that the user is controlling the movement of the mapping model. For the execution subject of this method, the position and orientation of the mapping model are adjusted according to the adjustment instructions; the user's visual information is obtained in real time, and the display status of the mapping model is updated according to the visual information; the user's audio information is obtained under an independent channel, the mapping model is used as the sound source, the audio information is inserted, the position, orientation, display status and audio information of each mapping model are counted in real time, and all mapping models in the virtual network space are updated.
