Description

Title of the invention: SYSTEM FOR VISUALIZING AN INTERIOR ARCHITECTURE PROJECT WITHIN A PHYSICAL SPACE, AND EXPERIENCE ROOM COMPRISING SAID SYSTEM

[0001] The present invention relates to a visualization system for an interior design project within a physical space. The invention further relates to an experimental room comprising the aforementioned system.

[0002] In particular, the "experience room" referred to is a room, and therefore a physical environment, equipped with a system according to the invention.

[0003] The system according to the invention is particularly, but not exclusively, useful and practical for the construction sector, including both the renovation of existing buildings and the construction of new buildings, as well as for the sectors of interior design and the supply, production and assembly of furniture elements.

[0004] As is known, in the sectors mentioned above, an interior design project can be presented to a client (or potential client) by means of tools such as paper / digital drawings and / or a virtual rendering to be viewed on a computer.

[0005] While useful and practical, the tools mentioned above are not without drawbacks, notably their inability to provide the client (or potential client) with sufficient knowledge of the actual space required for the interior design project. For example, although some well-known tools give the client (or potential client) the perception of walking inside a home that has already been renovated, remodeled, or built from scratch, these same tools do not allow for the direct measurement of the space between two pieces of furniture or between two walls. However, this lack of knowledge generates uncertainty and insecurity for the client (or potential client), who does not know what to do and / or questions the appropriateness of the choices already made within the framework of the interior design project.

[0006] The main objective of the present invention is to overcome the limitations of the technique described above by designing a visualization system for an interior design project within a physical space that allows for a better understanding of the actual space required by an interior design project.

[0007] In the context of this task, one of the objectives of the present invention is to provide a system capable of reproducing, in an extremely precise manner, a virtual model of the interior architecture project within a physical space.

[0008] Another objective of the invention is to increase the knowledge of the client (or potential client) regarding the interior design project.

[0009] An additional objective of the invention is to design a system to improve assistance to the client (or potential client) in their architectural choices for a renovation, redevelopment or (re)construction project of a building, an interior space or a dwelling.

[0010] A fourth objective of this invention is to provide the client (or potential client) with an optimized immersive experience in the interior design project.

[0011] Finally, the present invention aims to create a system of high reliability, relatively simple to produce and economically competitive compared to a prior technique.

[0012] This task, as well as others which will become clearer below, can be achieved through a visualization system for an interior architecture project within a physical space.

[0013] The visualization system of an interior architecture project within a physical space includes a processing device configured to produce a virtual model of said interior architecture project in a virtual environment; characterized in that said system also includes a plurality of projection devices (P1-P10) functionally connected to said processing device, said projection devices (P1-P10) being configured to project images of said virtual model into said physical space, said physical space being in particular in an experiment room.

[0014] In one embodiment of the system, a virtual model includes a plan, walls, floors and / or furniture of a dwelling.

[0015] In one embodiment of the system, the images of said virtual model reproduce at a 1:1 scale one or more details of said interior design project.

[0016] In one embodiment of the system, the projection devices (P1-P10) comprise: a first group of projectors (P1-P6), configured to project said images of said virtual model onto the floor; and a second group of projectors (P7-P10), configured to project said images of said virtual model towards one or more walls of said physical space.

[0017] In one embodiment of the system, the first group of projectors (P1-P6) comprises six projectors arranged in particular in a rectangle (R), four projectors (PI, P3, P4, P6) among said six projectors (P1-P6) forming vertices of said rectangle (R), and the two remaining projectors (P2, P5) of said six projectors (P1-P6) being positioned along opposite sides of said rectangle (R), preferably symmetrically.

[0018] In one embodiment of the system, at least one projector (P8) of said second group of projectors (P7-P10) is arranged outside said rectangle (R).

[0019] In one embodiment of the system, the second group of projectors (P7-P10) comprises a first subgroup of projectors (P8, P10), configured to project said images of said virtual model towards a first wall of said physical space; and a second subgroup of projectors (P7, P9), configured to project said images of said virtual model towards a second wall of said physical space.

[0020] In one embodiment of the system, the second group of projectors (P7-P10) comprises four projectors arranged in particular in a cross, said second group of projectors (P7-P10) preferably being arranged at a lower height than said first group of projectors (P1-P6).

[0021] In one embodiment of the system, the physical space includes a display area used as a material library, and said projection devices (Pl-P10) are oriented opposite said display area.

[0022] In one embodiment, the system also includes a visualization device configured to: recognize said images of said virtual model, said images being projected into said physical space by said projection devices (PI-P 10); use one or more of said recognized images as a spatial anchor; and activate a three-dimensional visualization of one or more parts of said virtual model, based on said spatial anchor, said three-dimensional visualization including in particular at least one three-dimensional image, preferably at actual scale, of one or more walls and / or one or more furniture elements provided for by said interior design project.

[0023] In one embodiment of the system, the visualization device is also configured to operate in mixed reality.

[0024] In one embodiment of the system, the visualization device is also configured to: operate according to a first mode of operation, in which said visualization device operates autonomously with respect to said processing device; and / or operate according to a second mode of operation, in which said visualization device is connected to said processing device, in particular wirelessly.

[0025] In one embodiment of the system, the visualization device is also configured to receive said virtual model and / or any modification of said virtual model from said processing device.

[0026] In one embodiment, the experimental room includes a system.

[0027] Other features and advantages of the present invention will become more apparent upon reading the description of a preferred, but not exclusive, embodiment of the visualization system for an interior design project within a physical space according to the invention, illustrated by way of example and without limitation with the aid of the attached drawings, in which:

[0037] Fig. 9 is a detailed perspective view of the experiment room in Fig. 8.

[0038] In the description of preferred and illustrated embodiments, elements belonging to the same function group are indicated by a reference number containing the same digit.

[0039] In the figures cited, the system according to the present invention is indicated globally by the reference number 10, while the reference number 20 indicates a part (i.e. a physical space) in which the system 10 is present.

[0040] In particular, room 20 constitutes an "experience room", that is to say a physical space in which a client (or potential client) 15 can experience an interior design project intended for his own home (or, more generally, for a building) to be renovated, redesigned or built from scratch.

[0041] The system 10 includes a processing device (hereinafter, in short, "computer") 12.

[0042] Computer 12 is configured to produce a virtual model of the interior architecture project in a virtual environment.

[0043] In particular, the virtual environment referred to is a CAD (Computer-Aided Design) type environment. In other words, the virtual model can be a CAD model, for example in the form of a mesh.

[0044] The virtual model of the interior architecture project may include one or more of the following elements: one or more floors, one or more walls and / or one or more furniture elements of the dwelling or building to be renovated, redesigned or built from scratch.

[0045] In particular, the virtual model includes a plan 71, walls 73, floors 75 and / or furniture (or other furnishings) 77 of a dwelling.

[0046] The computer 12 can be either fixed or mobile. Preferably, the computer 12 is a personal computer (PC). However, other embodiments are also conceivable, in which the computer 12 is another type of electronic device (for example, a tablet or a smartphone). One or more functions of the computer 12 can be implemented remotely, for example, using cloud-type technologies.

[0047] Computer 12 can also be configured to modify the interior architecture project, in particular in real time.

[0048] In practice, the interior design project can be modified in real time, based on appropriate commands given by an operator 13. For example, when the interior design project concerns the renovation of a bathroom, the operator 13 can modify the interior design project in real time (via the computer 12) so as to slightly move the position of a shower relative to other furniture elements provided for by the same interior design project.

[0049] In the preferred and illustrated embodiments, the computer 12 is located in the room 20. In particular, the computer 12 is arranged in a cabinet (rack) 14. However, embodiments are also conceivable in which the computer 12 is arranged either in another location within the room 20, or outside the room 20.

[0050] In particularly advantageous preferred embodiments, the computer 12 is functionally connected to one or more multimedia displays 16, such as NEC™ M491 P CAP 49" touchscreens.

[0051] In particular, at least one of the multimedia panels 16 is installed in room 20. Another multimedia panel (of a similar or different type to the previous panel or panels) may be installed in a customer reception area located outside room 20.

[0052] The presence of the multimedia boards 16 is useful and practical for developing projects with clients, as well as for managing the projects themselves during the projection phase.

[0053] Furthermore, the system 10 also includes a plurality of projection devices P1-P10. In a preferred embodiment, the plurality of projection devices P1-P10 consists of ten video projectors.

[0054] Advantageously, each P1-P10 projection device is a high-definition projector. In some embodiments, each P1-P10 projection device is a 3LCD projector, that is, a projector configured to generate images using three LCD (Liquid Crystal Display) panels (for example, an NEC™ PA804UL 8200 AL laser projector). In other embodiments, each P1-P10 projection device is a DLP (Digital Light Processing) projector, that is, a projector configured to generate images using steerable micromirrors (for example, a Barco™ projector or equivalent).

[0055] The projection devices P1-P10 are functionally connected to the computer 12.

[0056] Preferably, the projection devices P1-P10 are arranged as illustrated in Figures 1 and 2.

[0057] However, embodiments are also conceivable providing for a number of projectors other than ten (for example five or six), preferably arranged in proportion to what is illustrated therein.

[0058] The projection devices P1-P10 are configured to project images of the virtual model into physical space 20.

[0059] In practice, the projection devices P1-P10 are used to project into room 20 the interior architecture project carried out in the virtual environment of computer 12, while computer 12 is dedicated to managing the content (i.e. the images) to be projected.

[0060] In particular, computer 12 is also configured to control the projection devices P1-P10.

[0061] The control of the projection devices P1-P10 can be implemented through an appropriate application (or program) installed in the computer 12. Such an application can be, for example, the D5 Render software, designed to scale and broadcast video content.

[0062] In addition, an overlap between the different projectable images by the projection devices P1-P10 can be managed by at least one, preferably a plurality of, multimedia servers (not illustrated) (for example, a Dataton™ Watchpax™ 62S 4x4 K OUT) functionally connected to the computer 12.

[0063] In the preferred and illustrated embodiments, the aforementioned overlap may relate to:

[0064] - the projection devices P1-P6, which are collectively configured to project a unique image on floor 60;

[0065] - the P7-P10 projection devices, which are collectively configured to project a single image onto wall 62.

[0066] In practice, each of the images on the ground 60 and on the wall 62 is the result of the (partial) overlap of a plurality of distinct images. For example, in Figures 4 to 6:

[0067] - the image on the ground 60 is projected by the six projection devices P1-P6, by partial overlap of six distinct images that are projected, respectively, by the same six projection devices P1-P6; and

[0068] - the image on the wall 62 is projected by the four projection devices P7- P10, by (partial) overlap of four distinct images which are projected, respectively, by the same four projection devices P7-P10.

[0069] Each multimedia server is functionally connected to at least one respective projector belonging to the plurality of projection devices P1-P10.

[0070] Preferably, each media server is equipped with four 4K HDMI outputs. Each media server can be functionally connected to a maximum of four respective projectors belonging to the plurality of projection devices P1-P10.

[0071] Each multimedia server can be installed in cabinet 14, that is to say in the same cabinet where computer 12 is located.

[0072] The management of the multimedia servers can be carried out through an appropriate application (or program) installed in the computer 12. For example, this application can be the Watchout 6 software, designed to manage and configure Dataton™ multimedia servers.

[0073] In practice, each video signal emitted by the computer 12 is transported from one of the outputs of the multimedia servers to the respective projectors (for example, via a CAT 6 LAN cable).

[0074] When the plurality of projection devices includes the ten projection devices P1-P10, the multimedia servers are preferably three in number.

[0075] Preferably, the system 10 also includes a plurality of extension devices (not shown), in particular of the HDBase-T type (for example, a Kramer™ TP-580T extender).

[0076] Each extension device is functionally connected to both the computer 12 and a respective projector belonging to the plurality of projection devices P1-P10.

[0077] The extension devices, which can be advantageously housed in the cabinet 14, are configured to convert each video signal emitted by the computer 12 into HDBase-T.

[0078] Preferably, the plurality of extension devices consists of a number of extension devices equal to the number of projection devices P1-P10.

[0079] In particular, the projection devices P1-P10 comprise: a first group of projectors, configured to project the images onto the floor towards (or onto) a floor 25 of the room (i.e. the physical space) 20; and a second group of projectors, configured to project the images towards (or onto) one or more walls 22, 24, 28 of the room 20.

[0080] In practice, each projector in the first group of projectors is arranged (approximately) vertically, so as to point downwards, i.e. towards the ground, and therefore towards the floor 25. Conversely, each projector in the second group of projectors is arranged (approximately) horizontally, so as to point towards a respective wall among the walls 22, 24 and 28.

[0081] Preferably, the second group of projectors is arranged at a lower altitude than the first group of projectors.

[0082] In the preferred and illustrated embodiments, the first group of projectors consists of the six projectors P1-P6, while the second group of projectors consists of the four projectors P7-P10.

[0083] In some preferred embodiments, the four projectors P7-P10 are arranged in a cross. For example, in [Fig. 1], projector P7 is aligned with projector P9 along a first axis A1, projector P8 is aligned with projector P10 along a second axis A2, and the first axis A1 is perpendicular to the second axis A2.

[0084] In the preferred and illustrated embodiments, the six projectors of the first group of projectors are arranged in two rows.

[0085] In particular, the six projectors P1-P6 are arranged in a rectangle, that is to say in such a way as to form the perimeter of a rectangle R.

[0086] In practice, four of the six projectors P1-P6 (more precisely, projectors PI, P3, P4 and P6) form respective vertices of rectangle R. Conversely, the two remaining projectors (i.e. projectors P2 and P5) are positioned along opposite sides of rectangle R.

[0087] Preferably, the projectors P2 and P5 are arranged symmetrically along the respective sides of the rectangle R.

[0088] The second group of projectors may comprise: a first subgroup of projectors, configured to project the images towards a first wall of the physical space 20 (in particular, towards wall 24); and a second subgroup of projectors, configured to project the images towards a second wall of the physical space 20 (in particular, towards wall 22). Thus, the second group of projectors consists of at least four projectors (two for each wall 22, 24).

[0089] In the preferred and illustrated embodiments, the first subgroup of projectors consists of projectors P8 and P10, while the second subgroup of projectors consists of projectors P7 and P9.

[0090] In practice, when the system 10 is in operation, the image on the floor 60 is the result of the overlapping of the images projected by a plurality of projectors belonging to the first group of projectors. On the other hand, the image on the wall 62 is the result of the overlapping of the images projected by a plurality of projectors belonging to the second group of projectors.

[0091] In some preferred embodiments, the projection devices P1-P10 include motorized lenses.

[0092] In particular, the first group of projectors includes first-type motorized lenses (functionally connected to projectors P1-P6), while the second group of projectors includes second-type motorized lenses (functionally connected to projectors P7-P10).

[0093] Preferably, second type motorized lenses have a higher throw factor than first type motorized lenses.

[0094] In particular, when the projection factor of the first type of motorized lenses is 0.6-0.75:1, the projection factor of the second type of motorized lenses is 0.79-1.11:1. For example, the first type of motorized lenses may be NEC™ NP50ZE (0.6-0.75) lenses, while the second type of motorized lenses may be NEC™ NP50ZE (0.79-1.11) lenses.

[0095] Preferably, each projector in the first group of projectors is configured to project images with dimensions of approximately 5.5 x 3.5 m.

[0096] In particular, when the first group of projectors is arranged about 3.3 m from the ground, each projector (P1-P6) of the first group of projectors projects an image of 5.50 x 3.45 m.

[0097] Preferably, each projector in the second group of projectors is configured to project images with dimensions of approximately 6.2 x 3.9 m.

[0098] In particular, when the second group of projectors is arranged approximately 2.7 m from the ground and each projector (P7-P10) of the second group of projectors is at 3.7 m from its respective wall (22 or 24), each projector in the second group of projectors projects an image of 6.24 x 3.90 m.

[0099] Particularly advanced preferred embodiments involve the use of advanced algorithms for image rendering and real-time projection management. In this way, the projection technology used allows for extremely precise synchronization between the plurality of projection devices P1-P10.

[0100] In some preferred embodiments, the physical space (i.e. the room) 20 includes a display area used as a materials library 30, where "materials library" means, as is known, a display space for a sample of materials 34 and / or objects 36 which may be intended, for example, for renovation and furnishing interventions.

[0101] In some preferred embodiments, the display / materials library area 30 includes a plurality of displays.

[0102] In particular, materials library 30 includes:

[0103] - at least one bathroom display stand, for displaying sanitary appliances 36A and / or other 36 items for a bathroom; and

[0104] - at least one tile display stand, for the tile display 34A.

[0105] Preferably, each bathroom display stand has a tubular structure (more precisely, 30 x 30 x 3 mm) with thickened boards to accommodate the 36A sanitary appliances.

[0106] Preferably, each tile display stand has a structure comprising:

[0107] - a base made of tubular material (in particular, 30 x 30 x 3 mm); and

[0108] - an upper part (also made of tubular material), comprising an element of U-shaped retainer equipped with a descending sealing bar.

[0109] Preferably, the projection devices P1-P10 are oriented opposite the display area / material library 30.

[0110] In the preferred and illustrated embodiments, the display area / material library 30 is a longitudinally developed shelving structure arranged along the wall 28.

[0111] Advantageously, the structure of the material library 30 comprises one or more shelves 32. Preferably, each shelf 32 has sides with dimensions not less than 10 cm.

[0112] Preferably, the shelves 32 of each bathroom display stand are made of tubular material (in particular, 30 x 30 x 3 mm), with a plexiglass support having a thickness of 10 mm.

[0113] Advantageously, the shelves 32 of each bathroom display are movable.

[0114] Although not visible in the figures cited, in some preferred embodiments, the material library 30 includes wheels configured to slide inside a plurality of rails.

[0115] In particular, the plurality of rails is fixed to the ground (i.e. on the floor 25).

[0116] Preferably, the rails are made of high-strength steel, in particular of galvanized steel.

[0117] Advantageously, the structure of the material library 30 can be welded in one piece to ensure that it slides smoothly relative to the rails.

[0118] In practice, the material library 30 can constitute a system made with interlocking panels resting on the rails, and the structure of the material library 30 can be made in the form of a welded support structure fixed with special fixing screws.

[0119] In some preferred embodiments, the structure of the material library 30 has a contour in tubular material (in particular, 30 x 30 x 3 mm), with retaining plates.

[0120] In preferred embodiments which include at least one tile display such as that mentioned above, the structure of the material library 30 can consist of several (for example, forty) tile-carrying panels made of 30 x 30 x 3 mm tubular material with internal 20 x 20 x 3 mm tubular materials for fixing the tiles with special hooks made with "U" bars and clamping screws with sealing gaskets.

[0121] In particular, each tile-carrying panel is designed to support approximately 80 kg of weight.

[0122] In practice, the structure of the material library 30 can essentially consist of boards, contours, tubes and tubular structural materials all made of S235JR steel (in addition to possible bolts according to standard EN 15048).

[0123] Advantageously, the structure of the materials library 30 is designed so that the materials 34 and / or objects 36 are easily visible from the center of the room 20. For example, the materials library 30 may have a white display structure, while the materials 34 may be housed in compartments with a black background to highlight the materials 34 themselves. In addition, the compartments may be illuminated by LED strips (not shown) embedded in the corners of the shelves 32.

[0124] Advantageously, the visibility of materials 34 and / or objects 36 can be improved by means of lighting techniques (preferably sequential) manageable by home automation directly from an operating workstation (for example, via the computer 12 and / or via another electronic device such as a tablet or smartphone).

[0125] Preferably, the structure of the material library 30 has a water-based satin enamel finish, treated with a hardenable resin.

[0126] Advantageously, the structure of the material library 30 can be compartmentalized by a motorized vertical mobile blind 38.

[0127] In particular, the movable blind 38 can be moved between a lowered position, in which the movable blind 38 hides the material library 30, and a raised position, in which the movable blind 38 makes the material library 30 visible, and therefore the materials 34 and / or objects 36 to be displayed.

[0128] In the raised position, the mobile blind 38 can be hidden by a false ceiling 21 of the room 20.

[0129] Although not visible in the figures cited, the false ceiling 21 may house an air cooling system for room 20.

[0130] Advantageously, the walls 22, 24, 26 of room 20 may have an exterior surface with a neutral reflection coefficient. Advantageously, the floor 25 of room 20 may have an exterior surface with a neutral reflection coefficient. In this way, the risk of unwanted reflections of the images projected by the plurality of projection devices P1-P10 can be minimized.

[0131] In some preferred embodiments, the system 10 also includes a display device 50.

[0132] In the context of the invention, "visualization device" means a portable electronic device, such as the device known as Meta™ Quest 3.

[0133] In particular, the viewing device 50 is adapted to be worn in the manner of a mask / glasses (in English: goggles) by the customer / potential customer 15, as illustrated for example in Figures 7A to 9.

[0134] Advantageously, the visualization device 50 can (be configured to) operate in mixed reality. In other words, the visualization device 50 can display a visualization environment in which at least one virtual object (i.e., one or more intangible objects, extracted from the virtual model) and at least one physical object (i.e., one or more objects tangibly present in physical space 20) can coexist and interact with each other in real time.

[0135] In practice, the visualization environment shown by the visualization device 50 makes it possible to visualize in a realistic (and customizable) way both any physical object in the physical space 20 and at least one virtual object of the virtual model, so as to simulate the presence of this same at least one virtual object in the physical space 20.

[0136] Advantageously, the display device 50 is configured to:

[0137] - recognize the images of the virtual model that are projected into physical space 20 by the projection devices P1-P10;

[0138] - use one or more of the recognized images as a spatial anchor (i.e. as a spatial reference point); and

[0139] - activate a three-dimensional visualization of one or more parts of the model virtual based on spatial anchoring.

[0140] In practice, the visualization device 50 allows the customer / potential customer 15 to visualize in three dimensions at least a part of the virtual model which is projected into the physical space 20, thus giving the customer / potential customer 15 the impression of being inside the same virtual model.

[0141] Image recognition (or tracking) can be achieved using so-called "computer vision" (or "artificial vision") techniques, which allow the virtual model to be placed in physical space 20 (and, consequently, in the viewing environment) with high precision.

[0142] In particular, image recognition can rely on so-called "tracking marker-based" algorithms, i.e. tracking algorithms that use at least one marker.

[0143] In practice, in the figures cited, the display device 50 can:

[0144] - recognize each image on the floor 60 and / or each image on the wall 62 in physical space 20;

[0145] - associate a respective marker to each recognized ground image 60 and / or to each image on wall 62 recognized;

[0146] - modify the position / orientation of one or more virtual objects of the model virtual, based on each marker; and, subsequently,

[0147] - display one or more virtual objects in the viewing environment, so that each virtual object appears as a respective three-dimensional entity positioned within physical space 20.

[0148] In practice, activating the three-dimensional visualization allows the operator 13 to switch from a first mode of operation, in which the system 10 exclusively provides two-dimensional images to the customer / potential customer 15, in particular via two or more of the projectors P1-P10 (see for example Figures 4 to 7A), to a second mode of operation, in which the system 10 provides three-dimensional images to the customer / potential customer 15, in particular via the viewing device 50 (see for example Figures 8 to 9).

[0149] Spatial anchoring is preferably persistent, in order to maintain spatial consistency throughout the model, even in the event of a temporary loss of image tracking.

[0150] The three-dimensional visualization of each part of the virtual model may include at least one three-dimensional image of one or more walls 73 and / or one or more furnishings 77 (for example, furniture, household appliances and other objects) envisaged by the interior design project.

[0151] In each three-dimensional image, each wall or piece of furniture is preferably at actual scale (i.e., at a 1:1 scale), so as to have dimensions corresponding to those that the same wall / piece of furniture would have if it were tangibly present in physical space 20.

[0152] In practice, the visualization device 50 represents an immersive tool that allows the client / potential client 15 to interact in real time with one or more three-dimensional virtual environments that are based on the interior architecture project.

[0153] The display device 50 can be functionally connected to the computer 12.

[0154] In particular, the display device 50 can communicate with the computer 12 in a bidirectional manner.

[0155] In practice, the viewing device 50 can enable mixed reality interaction with visual objects (for example, a preview of a color change of a wall), as well as provide mixed reality visualization of changes (for example, a movement of a piece of furniture, a replacement of one object by another, etc.) which can be sent in real time from the computer 12 to the viewing device 13.

[0156] A connection / communication between the display device 50 and the computer 12 can be wired or wireless (for example: a Wi-Fi or Bluetooth connection).

[0157] Depending on the requirements, the display device 50 can operate in any of the following cases:

[0158] - a first mode of operation, called "autonomous", in which the device Visualization 50 operates independently of computer 12; and / or

[0159] - a second mode of operation, called "Air Link", in which the device visualization 50 is connected (wirelessly) to computer 12.

[0160] The "standalone" mode offers freedom of movement, ease of use, and simple cable-free operation. In contrast, the "Air Link" mode utilizes the connection to the computer 12 to achieve superior graphics quality, greater model complexity, and performance exceeding that achievable with the "standalone" mode.

[0161] Advantageously, the display device 50 can receive the virtual model and / or any modifications to the virtual model from the computer 12. In other words, the computer 12 can act as a "configurator" of the display device 50. However, other embodiments are also conceivable in which the "configurator" of the display device 50 is a device other than the computer 12.

[0162] In practice, the visualization device 50 can not only provide a three-dimensional visualization of one or more projected parts of the virtual model (for example, in Figures 8 to 9, a three-dimensional view of the walls 73 and each piece of furniture 77), but also show in three dimensions and in real time any update to the virtual model, based on commands given by operator 13 to the "configurator" (i.e., in the figures cited, the computer 12). In this way, the system 10 offers the customer / potential customer 15 a synchronized immersive experience, during which the customer / potential customer 15 has the impression of moving within a realistic space updated based on their tastes and choices.

[0163] In particularly advanced preferred embodiments, at least one of the viewing device 50 and the computer 12 can be functionally connected to a server 19 (i.e., a remote processing device) configured to operate as a central "hub" for the entire system 10.

[0164] The server 19 can manage any data flow between the visualization device 50 and the computer 12. For example, the server 19 can store configurations, projects and / or assets, as well as maintain consistency between the three-dimensional visualization provided by the visualization device 50 and the commands of the operator 13.

[0165] Advantageously, the server 19 can manage communication between the display device 50 and the computer 12, in particular according to a low-latency client-server model preferably based on bidirectional WebSockets. In this way, the server 19 allows immediate transmission of events and commands (e.g., material changes, object movements, scene updates) from the computer 12 to the display device 50.

[0166] In practice, when computer 12 is the "configurator" of the display device 50, computer 12 can be configured to perform one or more of the following functions:

[0167] - load and select predefined projects (for example, via from server 19; or via one or more three-dimensional models provided by the client / potential client 15);

[0168] - present (on screen) a graphical interface allowing modification of the assets / materials / layouts of each internal environment of the interior architecture project;

[0169] - Connect to the viewing device 50 for a real-time update modifications made to the virtual model;

[0170] - store configuration snapshots;

[0171] - export proposals;

[0172] - record sequences.

[0173] The viewing environment displayed by the viewing device 50 can be generated, organized and / or managed on the basis of the following steps.

[0174] In a first step, the computer 12 can (be configured to) generate, receive, or select a specific three-dimensional model of one or more environments to be renovated, refurbished, or built from scratch. For example, the computer 12 can receive the specific three-dimensional model of the client / potential client 15 in the form of a CAD model in which each wall 73 is rendered so as to be identifiable (and possibly movable / separable) among the remaining entities present within the same CAD model.

[0175] In a second step, the computer 12 can associate each object (furniture item, configurable element) present in the specific three-dimensional model with a respective spawn point, defining the position and orientation of each object to be displayed in a desired scene within the viewing environment via the respective spawn point. Each object can be associated with a unique identifier, thus making any replacement, manipulation, or modification (for example, in terms of color / material) of the same object faster via the "configurator" of the viewing device 50.

[0176] In a third step, at least two projection devices (belonging to the plurality of projection devices P1-P10) can project a plurality of images of the specific virtual model into the physical space 20 (so as to obtain, for example, each image on the floor 60 and / or each image on the wall 62).

[0177] In a fourth step, the visualization device 50 can perform a detection of the plurality of images of the specific virtual model, so as to recognize (or “lock”) one or more reference images selected from among the images of the specific virtual model that have been projected into the physical space 20.

[0178] In a fifth step, the viewing device 50 can generate the desired scene in the viewing environment and keep the same scene anchored to each reference image.

[0179] The recognition of reference images (or "active tracking") can be guided by visual prompts, with the possibility of explicit confirmation of correct alignment (possibly via audio support).

[0180] Image tracking may include a comparative analysis between tracking scenarios of different complexity.

[0181] In particular, the visualization device 50 can evaluate one or more of the following:

[0182] - a complete follow-up scenario, based on what is called segmentation (or " slicing") of each image on the floor 60 recognized and / or of each image on the wall 62 recognized;

[0183] - a simplified scenario, based on the use of one or more markers simplified (for example, a clearly visible logo projected onto the floor) and / or the use of one or more predefined reference points on the floor and / or on at least one of the room's walls (using ad hoc projections). For example, the display device 50 may include sensors to determine the display device's height relative to the floor, and the display device 50 may be calibrated based on these sensors.

[0184] The full tracking scenario guarantees maximum freedom of movement, as well as greater accuracy and reliability than the simplified scenario.

[0185] In particular, when the client / potential client 15 provides complete images of plans and / or detailed renderings of interior spaces, the segmentation allows for optimized anchors.

[0186] In practice, the complete tracking scenario relies on algorithms configured to efficiently divide each image into smaller sections (ranging in size from about 1 x 1 m to about 1.5 x 1.5 m), thus ensuring optimal image tracking and stability.

[0187] In a complete tracking scenario, image tracking may include a preliminary phase and an experimental phase following the preliminary phase. During the preliminary phase, the display device 50 may perform "active tracking" of a specific scene. During the experimental phase, the display device 50 may maintain the specific scene anchored via persistent spatial anchoring, with periodic or on-demand synchronization (e.g., in the case of misalignments reported by the operator 13 and / or the customer / prospective customer 15). This approach reduces the possibility of errors and allows for a smoother data flow.

[0188] The operation of the system 10 according to the invention is clearly and obviously apparent from what has been described.

[0189] Essentially, the system 10 uses 1:1 scale projection technology based on the use of high-definition video projectors, which are capable of mapping the virtual model of the interior design project and faithfully reproducing every tiny detail of the same interior design project (with a resolution on the order of one square centimeter) in room 20. Therefore, when room 20 is equipped with the system 10, activating the system 10 transforms room 20 into an experience room in which the client / potential client 15 can see, and Therefore, to experiment, a virtual reconstruction at a 1:1 scale of the interior architecture project.

[0190] In practice, when system 10 is in operation, the experimental room allows:

[0191] i. walking through real spaces that simulate at a 1:1 scale all the spaces and aesthetic aspects that an architectural project envisions for each room, corridor or area of ​​a dwelling to be renovated, redesigned or built from scratch, thus helping the client / potential client 15 to understand and become aware of the real space required by the architectural project itself;

[0192] ii. display on one or more walls of room 20 and / or on the floor 25 at least one item of furniture that the architectural project includes within the dwelling mentioned in point i above;

[0193] iii. to live an immersive experience within a physical environment in which there is a 1:1 scale reproduction of a virtual model of one or more rooms of the dwelling referred to in point i and / or point ii.

[0194] For example, in [Fig.4], the client / potential client 15 can experience the space that the architectural project envisions for certain furniture elements 40, 42, 44 of a kitchen, thanks to the projection of the image onto the floor 60 and the image onto the wall 62 (which reproduce, respectively, a top view and a front view of the same furniture elements 40, 42, 44).

[0195] Advantageously, the immersive experience mentioned above can also be improved from an acoustic point of view, through one or more construction details of the experience room.

[0196] In particular, the side walls 22, 24, 26, 28, the false ceiling 21 and / or a (sliding) door 23 of room 20 may be made (at least in part) of sound-absorbing material. In addition or as an alternative, room 20 may include a sound diffusion system comprising a plurality of loudspeakers (for example, four integrated loudspeakers).

[0197] In addition, the experience room can be equipped with an advanced home automation system that allows the customer / potential customer 15 to interact with the projected environment via mobile devices such as tablets or smartphones. In technologically advanced embodiments, this home automation system can allow for real-time modification of configurations, colors, and materials, offering an even more personalized immersive experience.

[0198] In practice, the system 10 allows the customer / potential customer 15 to view, modify and personalize renovation / redevelopment / (re)construction projects directly in the physical space 20, allowing the same customer / potential customer 15 to experience any renovated / redeveloped / (re)constructed environment even before the same environment is physically built (thus reducing the risk of modifications during renovation / remodeling / (re)construction work). Furthermore, system 10 allows for the comparison of several solutions and the immediate evaluation of the impact of aesthetic and functional choices in a simple way (by moving around the room 50), with a high degree of visual and spatial consistency. Consequently, the level of awareness, participation, and involvement of the client / potential client 15 in the design phase is increased.

[0199] The advantages associated with the use of system 10 can be better understood by referring to the following concrete application example Ex.l.

[0200] Ex. 1: designing a new house

[0201] If customer 15 wishes to design a new house, the system 10 allows projecting onto the floor of room 20 not only the house plan, but also the furniture, appliances, and spaces planned for several bedrooms in the new house. In this way, customer 15 can move around within a projected reconstruction of the house, trying to simulate everyday actions such as cooking or cleaning.

[0202] By simulating these actions, customer 15 can highlight critical problems with the planned workspace between different furniture items or different rooms in the house. Operator 13 can then modify the interior design project in real time to expand the space between the different bedrooms and / or rooms in the new house. Once the modification is complete, the images projected within room 20 are updated according to the modified project: customer 15 can now move around within a new projected reconstruction (update) of the new house and decide whether or not the modification of the interior design project has overcome the critical problems previously highlighted.

[0203] In practice, it has been found that the present invention fully achieves the task and objectives intended.

[0204] In particular, it has been found that the system thus designed makes it possible to project every small detail of a dwelling at a 1:1 scale, thus making it possible to overcome the qualitative limitations of previous techniques.

[0205] In practice, when the system according to the invention is installed in a room such as the one mentioned above, an experience room (or "immersive room") is obtained that allows a client (or potential client) of a renovation, redevelopment, or construction project for a building (or part of a building) to experience and immerse themselves in the environment envisioned by an interior design project for the building (or part of a building) to be renovated, redeveloped, or constructed, even before the implementation of that same interior design project. Therefore, The system according to the invention is particularly useful for anyone who needs to renovate their home, remodel their home / condominium, build a new house from scratch, or simply change one or more pieces of furniture.

[0206] The system according to the invention is designed to be modular, reusable and scalable.

[0207] In practice, each project will be able to have its own set of images to project and / or track, as well as three-dimensional models and customization options (for example, materials, furniture elements, finishes), thus making the whole system scalable and opening the door to future developments in different contexts.

[0208] In addition, the "experience room" can enable the client to better understand one or more of the following: the dimensions of the different rooms; the size of one or more pieces of furniture within the room; the layout of each individual room; the color of the floor; the dimensions, layout and aesthetics of the doors and interior walls (e.g., painted or wallpapered); and the combination of the different elements which, at the end of the renovation, remodeling or construction project, will constitute the renovated, remodeled or constructed building or dwelling.

[0209] The invention thus conceived is capable of receiving numerous modifications and variants, all falling within the scope of the attached claims.

[0210] Unless otherwise specified, the various embodiments described above can be combined to provide additional and / or alternative embodiments. Furthermore, this description covers combinations of variants and preferred embodiments not explicitly described. By way of example, the plurality of projection devices may be arranged differently and / or comprise a different number of projection devices than those described herein.

[0211] Moreover, all the details can be replaced by other technically equivalent elements.

[0212] In practice, the materials used, provided they are compatible with the specific use, as well as the dimensions and possible shapes, can be any kind according to the needs and the state of the art.

[0213] In conclusion, the scope of protection of the claims should not be limited by the figures or preferred embodiments illustrated in the description by way of examples, but rather the claims should encompass all the new patentable features that reside in the present invention, including all features that would be treated as equivalent by the technique of the branch.
