Description

Technical Field

[0001] This application relates to the field of projection, and in particular to a polyhedral immersive projection system. Background Technology

[0002] As people's demands for visual experience continue to increase, immersive projection technology has become a key means for many fields to pursue excellent visual experience. It is widely used in entertainment venues (such as theme parks and virtual reality experience halls), education (such as virtual classrooms and science exhibitions), and commercial displays (such as product launches and shopping mall promotional activities).

[0003] Traditional immersive projection solutions often use a pentahedral space. The method of implementation is to use multiple sets of optical engines, each with a fixed number of components, to project and cover the ground and surrounding walls of a cube-shaped space.

[0004] However, this traditional pentahedral projection scheme reveals several significant drawbacks in practical applications. Firstly, poor immersion is one of the most prominent problems. From a spatial integrity perspective, the lack of a top projection in a pentahedral space prevents the formation of a complete visual enclosure. This causes viewers' visual attention to be easily distracted by the non-projected areas above, making it difficult to fully immerse themselves in the virtual scene. For example, in an immersive experience simulating a starry sky, without a top projection, viewers see only a regular ceiling, instantly disrupting the cosmic atmosphere and severely impacting immersion. From an environmental interference perspective, because the top is not covered by the projection, external light can more easily enter the experience space from above, creating a brightness contrast with the projected image and interfering with the viewer's visual perception. This interference is particularly pronounced in environments with less-than-ideal lighting, making it difficult for viewers to fully engage with the virtual scene and achieve a deeply immersive experience.

[0005] Secondly, regarding the content displayed, the limited information coverage of the top surface in traditional pentahedral projection presents numerous limitations. For complex scenes requiring comprehensive display, such as panoramic views of building interiors or natural environments showcasing the sky and earth, the lack of top-surface information results in an incomplete scene presentation, preventing viewers from acquiring complete scene information and diminishing the content's expressiveness. In special effects displays, many effects require visual supplementation from the top to achieve a stunning effect. For example, in simulating rain scenes, the absence of raindrop projection from the top significantly reduces the realism and impact of the entire scene. This not only limits the richness of projected content but also fails to meet the growing demand from users for high-quality, highly realistic immersive experiences, hindering the in-depth application and development of immersive projection technology in more fields. Summary of the Invention

[0006] This application provides a multi-faceted immersive projection system, which constructs a multi-faceted immersive space by designing a sloping surface at the top of a traditional pentahedral space to achieve immersive experience sensing and projection area.

[0007] To achieve the above effects, this application provides a multi-faceted immersive projection system, including: a multi-faceted projection space, including multiple wall surfaces arranged around each other, a top surface and a bottom surface disposed on the top side of each wall surface, wherein the top surface is inclined relative to the wall surfaces and the multiple top surfaces surround each other to form a top opening; a projection component placed in the top opening for projecting images onto the wall surfaces and the top surface.

[0008] Compared with existing technologies, this technical solution has the following characteristics and beneficial effects:

[0009] 1. Significantly enhances the immersive experience. By adding four slanted templates to construct the ceiling, the original pentahedral projection space is transformed into a polyhedral space, greatly enhancing the space's enclosure and integrity. Viewers are visually surrounded by the projected image, significantly reducing external environmental interference and allowing them to more naturally integrate into the virtual scene, feeling as if they are actually there, resulting in a qualitative leap in immersion.

[0010] 2. Expanded Projection Area. The newly added slanted template not only creates a top projection but also increases the overall projection area. The combination of slanted and straight walls, compared to traditional pentahedral projection, can display more scene details and elements.

[0011] 3. Increased projection realism. The multi-faceted projection structure makes the transition of the scene from various angles more natural and smooth. Due to the increase in projection area and the improvement of spatial integrity, the lighting effects and spatial relationships of objects in the scene can be presented more accurately, making it difficult for viewers to distinguish between virtual and reality.

[0017] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numerals in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with one or more embodiments of this specification. Rather, they are merely examples of apparatuses and methods consistent with some aspects of one or more embodiments of this specification as detailed in the appended claims.

[0018] It should be noted that the steps of the corresponding methods are not necessarily performed in the order shown and described in this specification in other embodiments. In some other embodiments, the methods may include more or fewer steps than described in this specification. Furthermore, a single step described in this specification may be broken down into multiple steps in other embodiments; and multiple steps described in this specification may be combined into a single step in other embodiments.

[0019] Example 1

[0020] The multi-faceted immersive projection system provided by this solution differs from the traditional pentahedral projection space by adding an inclined top surface to create a multi-faceted immersive projection space with a better immersive experience and a larger projection area.

[0021] like Figure 1 As shown, the polyhedral immersive projection system provided in this solution includes:

[0022] The polyhedral projection space 10 includes a plurality of wall bodies 11 arranged around the perimeter, a top body 12 and a bottom body 13 arranged on the top side of each wall body 11, wherein the top body 12 is inclined relative to the wall body 11 and the plurality of top bodies 12 surround to form a top opening 100.

[0023] The projection component 20, located in the top opening 100, is used to project images onto the wall body 11 and the top body 12.

[0024] The polyhedral projection space 10 constructed in this scheme is a polyhedral space composed of a wall body 11, a top body 12, and a bottom body 13. This structural design transforms the projection space from a traditional pentahedron into a polyhedron, increasing the integrity of the space and the sense of visual enclosure. The polyhedral space has only one top opening 100, and the opening size of the top opening 100 is smaller than the opening size of the surrounding space formed by the wall body 11. This allows the projection component 20 located at the top opening 100 to project the image diffusely onto the wall body 11 and the top body 12, while reducing the interference of light reflection on the projected image, improving the contrast and clarity of the image, and achieving more comprehensive and uniform image coverage.

[0025] In this embodiment, multiple wall surfaces 11 of the polyhedral projection space 10 are connected in pairs to form a surrounding space with its sides connected end to end. The opening size of the surrounding space is smaller than the opening size of the top opening 100, thus creating an immersive projection space that is smaller at the top and larger at the bottom. This design visually creates a strong sense of envelopment for the audience. From the audience's perspective, when in such a projection space, the larger space at the bottom allows the audience to move their bodies more freely without feeling uncomfortable due to the cramped space, while the gradually narrowing space at the top guides the audience's gaze to naturally focus upwards, enhancing their attention to the entire projection scene.

[0026] It should be noted that the shape of the surrounding space is not limited according to the actual projection requirements. The surrounding space can be one of the following: circular, elliptical, square, triangular, or trapezoidal, as long as the sides of the surrounding space are connected end to end.

[0027] For ease of structural design, each wall 11 in this design is perpendicular to the bottom surface 13, and adjacent wall 11 are connected to form a side-sealed surrounding space. Furthermore, to ensure the integrity of the projected image, each wall 11 in this design has the same height.

[0028] In a specific embodiment, the polyhedral projection space 10 includes four wall bodies 11 that surround and form a square. In this case, the polyhedral projection space 10 can modify a traditional square room so that the wall bodies 11 are set close to the walls of the room.

[0029] In this design, the top side of each wall 11 is inclined relative to the inner direction of the surrounding space, and the inclination structure between each wall 11 and top 12 is identical. The advantage of this design is that it creates a high degree of visual consistency within the projection space. When viewers move their gaze within the projection space, whether transitioning from the wall to the top or from one area to another, there is no visual abruptness due to sudden structural changes. For example, when displaying a fantasy forest scene, the transition from the vertical tree trunks (projection from wall 11) to the inclined canopies (projection from top 12) is natural and smooth, as if the viewer is truly immersed in the forest, enhancing the realism and immersion of the scene.

[0030] In some embodiments, the tilt angles of the wall surface 11 and the top surface 12 are between 110° and 150°. When the angles are within this range, from the viewer's perspective, the tilted top surface 12 can naturally blend into the visual field, seamlessly connecting with the projection of the wall surface 11 to jointly construct a visual field that fully envelops the viewer. Simultaneously, this angle range helps optimize the distribution of projected light, ensuring uniform brightness, contrast, and color on the wall surface 11 and the top surface 12, preventing light issues from disrupting the immersive atmosphere. Moreover, a reasonable tilt angle can reduce the possibility of external light entering through gaps at the top and sides, further enhancing the darkness and enclosure of the projection space, allowing the viewer to focus more on the virtual scene and fully immerse themselves in the immersive experience.

[0031] In some embodiments, the bottom body 13 is a plane parallel to the horizontal plane.

[0032] like Figure 2 As shown, Figure 2 This is a structural diagram of the wall surface 11 and the top surface 12 of the multi-faceted immersive projection system in this solution, with a tilt angle of 131°. Preferably, the tilt angle between the wall surface 11 and the top surface 12 in this solution is 130° or 131° to ensure the clarity of the projected image without sacrificing the three-dimensionality of the projection space. From a visual perspective, this angle allows the viewer's line of sight to naturally transition between the wall and the top surface, resulting in a comfortable viewing experience. In terms of projected image clarity, this angle allows light to be evenly distributed on the projection surface, effectively reducing light interference, enabling the projection components to focus precisely, and revealing every detail of the image.

[0033] In some embodiments, multiple top surfaces 12 are connected in pairs to form a top surface space with the sides connected end to end, and the top surface space has a top opening 100, and the top surface space and the surrounding space are connected to construct the projection space of the polyhedral immersive projection system.

[0034] Similarly, the shape of the top surface space is not limited according to the actual projection requirements. The top surface space can be one of the following: circular, elliptical, square, triangular, or trapezoidal, as long as the sides of the top surface space are connected end to end.

[0035] In some specific embodiments, when the polyhedral projection space 10 includes four wall surfaces 11 arranged in a square shape, it also includes four top surfaces 12 arranged in a trapezoidal shape. In this case, the upper part of the polyhedral projection space 10 is a trapezoidal structure, and the lower part is a square structure. The size of the top opening 100 is between 2m*2m and 4m*4m. In this case, the wall surfaces 11 and top surfaces 12 can be constructed in the room using a suspended ceiling, with the room floor serving as the bottom surface 13. Preferably, the size of the top opening 100 is 2m*2m.

[0036] In some embodiments, the interior of the wall body 11 and the ceiling body 12 is filled with sound-absorbing material, which may be sound-absorbing cotton or sound-absorbing foam. The sound-absorbing material can effectively absorb echoes and noise in the projection space, improve the acoustic environment, and enable the audience to hear clearer and purer sound effects when enjoying the projected image, thereby enhancing the overall effect of the immersive experience.

[0037] In some embodiments, the wall body 11 and the top body 12 are integrally formed. In other embodiments, to improve the structural stability of the wall body 11 and the top body 12, the wall body 11 and the top body 12 are connected by an angle connector. In this case, one end of the angle connector is fixed to the top edge of the wall body 11 by bolts, and the other end is connected to the top body 12 by a hinge structure. The tilt angle of the top body 12 can be precisely set by rotating the adjusting nut and locked after installation to ensure that the angle remains stable.

[0038] In some embodiments, the height of the projection component 20 is not less than the height of the top opening 100, and the projection component 20 is configured to project images toward the surrounding space of the wall 11 and the top space of the top surface 12. To facilitate the projection setup of the projection component 20,

[0039] like Figure 3As shown, the projection component 20 of this solution includes multiple sets of projection optical engines 21. Each projection optical engine 21 is positioned to project a wall surface 11 and a top surface 12. The number of projection optical engines 21 is the same as the number of wall surfaces 11. It should be noted that each wall surface 11 and the top surface 12 positioned on it form a group. Each projection optical engine 21 corresponds to one group of wall surfaces 11 and top surface 12. This arrangement allows for individual parameter adjustments to the projection optical engine 21, as the projection distances between the top surface 12, the wall surface 11, and the projection optical engine 21 are inconsistent, until the image is clearly displayed. For example, four sets of projection optical engines 21 can be set in a polyhedral projection space 10 composed of four wall surfaces 11. After adjusting the position of each set of projection optical engines 21, it is ensured that its projection direction accurately covers the corresponding wall surface 11 and top surface 12.

[0040] In other words, the projection engine 21 is set up with a set of top surface 12 and wall surface 11 as the target walls to ensure that the projected image of the projection engine 21 can cover the area of ​​the wall surface 11 and the top surface 12. The projection engine 21 can be equipped with a parameter adjustment system including an electric zoom lens, an electric focusing mechanism, and an automatic keystone correction function.

[0041] Preferably, each projection optical engine 21 is symmetrically distributed with respect to the center position of the corresponding wall body 11 and top body 12 to ensure the uniformity of the image across the entire projection surface. For example, when the wall body 11 is square, the projection optical engine 21 is located on the extension line of the diagonal of the wall body 11, and the distance from the wall body 11 and top body 12 is calculated and determined based on the focal length of the projection optical engine 21 and the size of the projection image, so that the projection image can completely and clearly cover the wall body 11 and top body 12, avoiding situations where the image exceeds or does not cover the projection area.

[0042] In some embodiments, each projection optical engine 21 is fixedly mounted at the top opening via an optical engine base 22. The parameters of the projection optical engine 21 are adjusted to project a polyhedral immersive space into the projection space. If installed in a room, the projection assembly 20, consisting of multiple projection optical engines 21, can be placed in the center of the room and suspended to a certain height above the ground, and fixed to the top opening via the optical engine base 22.

[0043] In some embodiments, the optical engine base 22 includes horizontal and vertical adjustment mechanisms. The horizontal adjustment adopts a combination of slide rail and fine-tuning screw. By rotating the fine-tuning screw, the position of the projection optical engine 21 in the horizontal direction is precisely adjusted to ensure that its projection direction is accurately aligned with the corresponding wall body 11 and ceiling body 12. The vertical adjustment utilizes a lifting screw mechanism so that the operator can easily adjust the height of the projection optical engine 21 according to the actual situation.

[0044] Those skilled in the art should understand that the technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments have been described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this application should be determined by the appended claims.
