[0041] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with specific embodiments and corresponding drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0042] In the traditional decoration process, users often feel that there is a big gap between the design and the actual scene. Or when choosing furniture and building materials, they cannot accurately imagine the actual effect after selection. In the prior art, a preview effect can be provided through a 3D model, so that users can achieve an experience close to "being there" so as to better understand the decoration effect.

[0043] However, in the prior art, the various building materials in the 3D model are often defined during the modeling process, and users cannot replace them in a simple way. If you want to replace some building materials in the rendering, you usually have to rely on the designer to re-model or readjust the model. In other words, during a modeling process, the user can basically only preview one effect, and cannot quickly and conveniently replace the various building materials in the model to achieve the purpose of building material screening.

[0044] In view of this, the present invention provides a building material display method based on digital twins. Figure 1 As shown, a specific embodiment of the building material display method based on digital twins provided by the present invention is shown. In this embodiment, the method includes:

[0045] Step 101: Load a spatial model corresponding to a target space in a digital twin system, and determine a display location in at least one of the spatial models.

[0046] Digital twin is a system that uses 3D models in virtual space to map physical space. Therefore, in this embodiment, this technology is used to realize the display of building materials. Compared with ordinary 3D modeling, digital twin has stronger flexibility and operability, so it provides the basic conditions for conveniently replacing building materials in the model. In addition, digital twin also has better visualization effect and can be displayed to users at almost any position and any angle, so it can further improve the browsing effect compared with the existing technology.

[0047] In this embodiment, the target space refers to a specific space in the physical world, such as a house that needs to be renovated. In the digital twin system, the target space can be mapped in advance to obtain a 1:1 complete space model. The structure, size and other spatial factors of the space model are consistent with the target space.

[0048] Before the user selects the building materials, the space model can be displayed to the user first. This is equivalent to a "rough house" in the physical world. Or if there are other building materials selected by the user in the space model, it can be equivalent to a "model room" in the physical world.

[0049] In the space model, several display positions can be pre-set. Display positions are used to carry and display building materials. For example, in actual decoration, the building materials corresponding to the ground can be floors, tiles, etc., and the building materials corresponding to the wall can be tiles, wall paint, wallpaper, etc. In addition, there will be doors, windows, furniture, cabinets, sanitary ware, etc. in the space. The corresponding positions in the space model can be set as display positions.

[0050] At this time, users can select building materials according to their needs and load them into the space model, or load them into the display position. For example, when users need to select a floor, they can determine the display position representing the "ground" in the space model, and the range of this display position can be equivalent to the entire ground range in the space model. In subsequent operations, building materials can be loaded for this display position to achieve visual display of building materials in the display position.

[0051] Step 102: In the virtual building material library, determine the candidate building material information corresponding to each display position, so that the user can determine the target building material information according to the candidate building material information.

[0052] The virtual building material library is a database that stores information about various building materials. Specific building material information can include its name, size, performance parameters, and visualization information. Depending on the type of building material, the specific visualization information can be the same 3D model, or it can be a flat map that can be attached to the model.

[0053] After the display position is determined, the candidate building material information corresponding to the display position can be further determined. In other words, it is possible to determine which types of building materials can be displayed on the display position, determine these building materials as candidate building materials, and then further determine their candidate building material information.

[0054] For example, when the "ground" display position is determined, it can be determined that the building material types corresponding to the display position are floor and tile. Therefore, the building material information of all floors and tiles can be screened out in the virtual building material library and used as candidate building material information.

[0055] Then the user can actively select a type of building material from the candidate building material information according to their own needs and use it as the target building material information. This means that the user has selected a certain floor or tile and hopes that it will be displayed on the "ground" display position.

[0056] Step 103: Determine the target to be displayed corresponding to the target building material information.

[0057] After determining the target building material information, the corresponding target to be displayed can be further determined. The target to be displayed refers to the data that will actually be displayed on the display position. The building material information may include its name, size, performance parameters and visualization information. The target to be displayed is actually equivalent to the above-mentioned visualization information. Its essence can be an independent 3D model, or it can be a flat map that can be attached to the model. On the other hand, the display position itself is also part of the spatial model, such as a plane of the model, or a specific position in the model. In short, the target to be displayed has the characteristic of being loaded on the display position.

[0058] When the display position is "ground" and the target building material information corresponds to a certain type of floor or tile, the target to be displayed may be a flat map, and the image content in the map is the surface pattern of the floor or tile.

[0059] Step 104: Display the object to be displayed at the display position.

[0060] After determining the target to be displayed, you only need to load it to the corresponding display position to complete the display of building materials. In other words, at this point, the selected building materials have been laid out in the space model, and users can browse their actual effects in the digital twin system.

[0061] It can be seen from the above technical solutions that the beneficial effects of this embodiment are: based on the digital twin technology, a corresponding virtual building materials library is established corresponding to the target space; the user only needs to determine the display position and select the building materials he wants to display, and the target to be displayed can be loaded on the display position, thereby realizing the display of the building materials; in this process, the user's operation is simple and convenient, and there is no need to re-model or readjust the model.

[0062] In some cases, after displaying the target to be displayed at the display position, the method further includes:

[0063] Determine the browsing position of the user; and determine a display effect diagram of the space model according to the browsing position, wherein the display effect diagram includes the target to be displayed displayed on the display position.

[0064] In this embodiment, based on the characteristics of the digital twin system, a 360° all-round browsing function can be provided to the user. That is, the user can select the location and sight direction in which he needs to browse in the spatial model, so as to display the display effect map that can be obtained by browsing there. The display effect map includes the target to be displayed on the display position, which means that the building material previously selected by the user will appear in the display effect map, so that the user can intuitively see the actual application effect of the building material.

[0065] In addition, in this embodiment, the building material types can be further divided into a first type and a second type. The first type includes, for example, floors, tiles, wall materials, doors, windows, etc. The first type of building materials is characterized by a nearly flat effect, so they can be presented in the form of flat mapping during the display process. The second type includes furniture, cabinets, and sanitary ware. The second type of building materials is characterized by having to occupy a certain space and present a three-dimensional effect, so they can be presented in the form of 3D modeling during the process. The two types of building materials are slightly different in the subsequent process, and will be described separately below.

[0066] like Figure 2 As shown, when the building material type corresponding to the display position is the first type, the specific steps are as follows:

[0067] Step 201: Determine candidate building material information of the first type of building material, so that a user can determine target building material information according to the candidate building material information.

[0068] Step 202: Determine the target to be displayed corresponding to the target building material information; the target to be displayed is a target map.

[0069] Step 203: In the virtual building material library, query the correspondence between the target building material information and the texture set, so as to determine the target texture.

[0070] Step 204: Display the target map at the display position.

[0071] In the case of the first type of building materials, the corresponding display position is often a plane in the space model, such as a wall, ground, etc. Therefore, you only need to "attach" the target map to the display position to complete the display.

[0072] like Figure 3 As shown, when the building material type corresponding to the display position is the second type, the specific steps are as follows:

[0073] Step 301: Determine candidate building material information of the second type of building material, so that the user can determine target building material information according to the candidate building material information.

[0074] Step 302: Determine the target to be displayed corresponding to the target building material information; the target to be displayed is a target model.

[0075] Step 303: In the virtual building material library, query the correspondence between the target building material information and the model set, so as to determine the target model.

[0076] Step 304: Display the target model at the display location.

[0077] In the case of the second type of building materials, the building materials themselves need to occupy a certain space and present a three-dimensional effect. Therefore, the second type of building materials need to be presented in the form of 3D models. In other words, displaying the second type of building materials is to further load some small 3D models into the space model. The display position represents the location where it is loaded, that is, the placement position of the second type of building materials in the space. Therefore, the display position can be used as an "anchor point" to load the second type of building materials into a specific position to complete the display.

[0078] In some cases, displaying the to-be-displayed object at the display position includes:

[0079] According to the size of the space model, the size of the object to be displayed is adjusted; and the adjusted object to be displayed is displayed at the display position.

[0080] Whether it is the first type of building materials or the second type of building materials, they need to meet specific size relationships when loaded into the space model. For the first type of building materials, they need to meet the specific shape of the display position and be fully laid on the display position. Building materials such as doors and windows also need to meet the proportional relationship with the space model. For the second type of building materials, they also need to meet the proportional relationship with the space model so that users can check whether they can be placed in certain positions. Or check the effect after placement, whether it is too crowded or too empty. Therefore, it is necessary to adjust the size of the target to be displayed according to the size of the space model so that the ratio of the two is consistent with the physical world. Then further present it in the display position.

[0081] like Figure 4 As shown in FIG. 1 , a specific embodiment of the building material display device based on digital twins of the present invention is shown. The device described in this embodiment is used to perform Figures 1 to 3 The physical device of the method. Its technical solution is essentially consistent with the above embodiment, and the corresponding description in the above embodiment is also applicable to this embodiment. The device in this embodiment includes:

[0082] The display location determination module 401 is used to load the space model corresponding to the target space in the digital twin system and determine a display location in at least one of the space models.

[0083] The target building material determination module 402 is used to determine the candidate building material information corresponding to each display position in the virtual building material library, so that the user can determine the target building material information according to the candidate building material information.

[0084] The to-be-displayed target determination module 403 is used to determine the to-be-displayed target corresponding to the target building material information.

[0085] The display module 404 is used to display the target to be displayed at the display position.

[0086] It can be seen from the above technical solutions that the beneficial effects of this embodiment are: based on the digital twin technology, a corresponding virtual building materials library is established corresponding to the target space; the user only needs to determine the display position and select the building materials he wants to display, and the target to be displayed can be loaded on the display position, thereby realizing the display of the building materials; in this process, the user's operation is simple and convenient, and there is no need to re-model or readjust the model.

[0092] The second type determination concern 432 is used to query the correspondence between the target building material information and the model set in the virtual building material library when the building material type corresponding to the display position is the second type, so as to determine the target model. The second type of building materials includes furniture, cabinets and sanitary ware.

[0093] The size adjustment module 406 is used to adjust the size of the object to be displayed according to the size of the space model.
