[0052] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all of the embodiments. The components of the embodiments of the present application generally described and shown in the drawings here can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the present application provided in the drawings is not intended to limit the scope of the application for protection, but merely represents the selected embodiments of the present application. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without making creative work are within the scope of protection of this application.

[0053] It should be noted that similar reference numerals and letters represent similar items in the following drawings. Therefore, once an item is defined in one drawing, it does not need to be further defined or explained in subsequent drawings. At the same time, in the description of this application, the terms "first", "second", etc. are only used to distinguish the description and should not be understood as indicating or implying relative importance.

[0054] Generally speaking, the effect of embedding a virtual real three-dimensional scene in a local space that people see cannot be achieved through shooting. The time and software calculation required to embed one scene space into another scene space through a three-dimensional scene is huge and the efficiency is low.

[0055] Please refer to Figure 1 , Figure 1 This is a flowchart of a method for establishing an embedding space provided by the present application, which includes the following steps:

[0056] S100, obtaining a first model, where the first model has a semi-enclosed space;

[0057] S200, extending along an inner side of the semi-enclosed space to obtain a depth space;

[0058] S300, obtaining a second model according to the depth space;

[0059] S400: Acquire a combined model based on the first model and the second model, wherein the combined model has a combined space inside and an appearance of the first model outside, and the combined space includes a connected semi-enclosed space and a depth space.

[0060] The method for establishing an embedded space provided in the present application extends the semi-enclosed space in the first model to obtain a depth space, thereby obtaining a second model, and combining the first model with the second model to obtain a combined model, so that the combined model has the appearance of the first model and has interconnected semi-enclosed space and depth space, thereby realizing the establishment of the embedded space. From a visual effect point of view, the appearance of the combined model is only the appearance of the first model, but the internal space of the combined model is the combined space of the semi-enclosed space in the first model and the depth space in the second model, so that the obtained embedded space ultimately appears larger than the semi-enclosed space in the first model.

[0061] Specifically, the first model has a semi-enclosed space inside, that is, the model has a one-way opening. The first model is a solid model, and the shape of the solid model is the shape of the entire embedded model.

[0062] Specifically, refer to Figure 2 The depth space is a space extending along the inner side of the semi-enclosed space, and the depth of the depth space is the depth of the second model.

[0063] Specifically, in some embodiments, the step of combining the first model with the second model is as follows: displaying the first model to obtain first data information, hiding the side model of the first model and displaying the second model to obtain second data information, the first data information and the second data information are sequence file data with an alpha channel with 32-bit information, adding a mask program to the second data information to highlight and partially mask the first model, and obtaining third data information that only retains the appearance of the first model and the interconnected semi-enclosed space and depth space, and finally overlaying the third data information on the first data information to obtain data information embedded in the space.

[0064] In some preferred embodiments, reference Figure 3 , Figure 3 A flowchart of the steps for obtaining the second model based on the depth space, the steps include:

[0065] S210, obtaining peripheral wall information of the depth space;

[0066] S220: Acquire a second model based on the surrounding wall information.

[0067] Specifically, the peripheral wall information is a thin-walled structure, and the space surrounded by the thin-walled structure and the side model is the depth space. The thin-walled structure and the depth space are combined to obtain the second model.

[0068] Specifically, in some embodiments, the side model may be a plane model or a curved surface model extending in a horizontal direction or a vertical direction, or a plane model or a curved surface model extending at a certain inclination angle.

[0069] Specifically, refer to Figure 4 The extension direction of the depth space is preferably the direction away from the opening of the first model. In some embodiments, the user looks into the first model through the opening of the first model. Through the first model, the user first sees the semi-enclosed space from near to far, and then sees the depth space. Generally, the scene established in the depth space is the background scene, so a visual effect of seeing a large space with a background scene in a small space of the first model can be obtained.

[0070] In some preferred embodiments, the first model includes a solid model and a side model, the semi-enclosed space is located inside the solid model, and the step of extending along an inner direction of the semi-enclosed space to obtain the depth space includes:

[0071] The depth space is obtained by extending the semi-enclosed space along the inner side of the solid model toward one side of the side model.

[0072] Specifically, refer to Figure 5 The solid model and the side model can be separated, that is, during the processing, the data of the solid model or the side model is hidden, and the side model or the solid model can be obtained separately. In some embodiments, when extending the semi-enclosed space to obtain the depth space, the existence of the side model blocks the extension of the semi-enclosed space, making the semi-enclosed space and the depth space unable to connect. In actual use, the user cannot see the depth space through the semi-enclosed space, and cannot see the scene of the large space through the first model. Therefore, it is necessary to hide the side model to obtain the interconnected semi-enclosed space and the depth space.

[0073] In some preferred embodiments, please refer to FIG. 6 , Figure 6 is a flow chart of the steps of obtaining a combined model based on the first model and the second model, the steps comprising:

[0074] S410, combining the first model and the second model to obtain a transition model, wherein the transition model has a connected semi-enclosed space and a depth space;

[0075] S420 , mask the portion of the transition model protruding from the first model according to the appearance of the first model to obtain a combined model.

[0076] Specifically, the transition model is a model that connects the first model with the second model so that the semi-enclosed space and the depth space are smoothly connected. There are semi-enclosed space and depth space in the transition model, and the semi-enclosed space is connected with the depth space. That is, in the process of combining the first model with the second model, the side model data is hidden so that the semi-enclosed space and the depth space are connected.

[0077] Specifically, the transition model is masked according to the appearance of the first model, so that the part of the transition model protruding from the first model is masked, and the combined model is obtained. The essence of masking is to hide the appearance of the second model in the transition model. The appearance of the combined model obtained after masking is the appearance of the first model, and the combined space inside the combined model includes a semi-enclosed space and a depth space, so that from the outside it is only the appearance of the first model, and from the inside the space, the semi-enclosed space and the depth space connected to it can be seen, achieving a visual effect of a small model and a large space.

[0078] In some preferred embodiments, please refer to Figure 7 , Figure 7 The flowchart is a step of combining the first model and the second model to obtain a transition model, wherein the transition model has a connected semi-enclosed space and a depth space, and the step includes:

[0079] S411, hiding the side model in the first model;

[0080] S412: Connect the first model and the second model after hiding the side model, so that the semi-enclosed space and the depth space are connected to obtain a transition model.

[0081] The method for establishing an embedded space provided in the present application obtains a combined space by extending a semi-enclosed space to obtain a depth space and combining it with the semi-enclosed space. The portion protruding from the first model is then masked, ultimately obtaining a visual effect of seeing a large space within the first model. This method makes the operational process of the embedded space clear and simple, and improves the efficiency of establishing the embedded space.

[0082] Secondly, refer to Figure 8 , Figure 8 A schematic diagram of a flow chart of a method for establishing an embedded model provided in this application, the method comprising:

[0084] S20, establishing second scene information in the semi-enclosed space;

[0085] S30, extending along an inner side of the semi-enclosed space to obtain a depth space;

[0086] S40, obtaining a second model according to the depth space;

[0087] S50, establishing third scene information in the depth space;

[0088] S60. Obtain a combined model based on the first model and the second model, wherein the combined model has a combined space inside and an appearance of the first model outside, and the combined space includes a semi-enclosed space with second scene information and a depth space with third scene information that are interconnected.

[0089] The method for establishing an embedded model provided in the present application obtains a combined model by combining a first model with second scene information with a second model with third scene information. The appearance of the combined model is the appearance of the first model, and the combined space within the combined model includes interconnected semi-enclosed spaces with second scene information and depth spaces with third scene information, so that the model is the appearance of the first model when viewed from the outside, and the combined scene of the second scene information and the third scene information can be seen when viewed from the inside, thereby achieving a visual effect of a small model and a large space.

[0090] Specifically, the first scene information is a scene having a first model. In some embodiments, the first scene information is the surrounding environment of the first model. By acquiring the first scene information, the first model in the first scene information is acquired.

[0091] Specifically, the second scene information is located in the semi-enclosed space in the first model. In some embodiments, the second scene information is generally the main scene information, displaying the main scene in the space. The scene information can be existing scene information, and the second scene information is added to the semi-enclosed space through an adding program. In other embodiments, the second scene information can also be newly established scene information in the semi-enclosed space.

[0092] Specifically, the third scene information is located in the depth space of the second model. In some embodiments, the third scene information is generally background scene information, which displays the background scene information within the space. The scene information can be existing scene information, and the second scene information is added to the semi-closed space through an adding program. In other embodiments, the second scene information can also be newly established scene information in the semi-closed space.

[0093] Specifically, in some embodiments, the step of combining the first model with the second model is specifically as follows: displaying the first model with the second scene information to obtain the first data information, hiding the side model of the first model with the second scene information and displaying the second model with the third scene information to obtain the second data information, the first data information and the second data information are sequence file data with an alpha channel of 32-bit information, adding a mask program to the second data information to highlight the partial mask of the first model, and obtaining the third data information that only retains the appearance of the first model and the interconnected semi-enclosed space with the second scene information and the depth space with the third scene information, and finally overlaying the third data information on the first data information to obtain the data information of the embedded model, and the final effect diagram of the embedded model is as shown. Figure 9 shown.

[0094] In some preferred embodiments, the first scene information, the second scene information, the third scene information, the data information of the first model and the second model all have texture information.

[0095] Thirdly, refer to Figure 10 , Figure 10 This is a schematic diagram of the structure of a device for establishing an embedded space provided in this application, the device for establishing an embedded space includes:
