Description

360-degree video production and projection system using polyhedral structures

[0001] The present invention relates to a 360-degree image production and projection system using a polyhedral structure, and more specifically, to a polyhedral camera that sets coordinate values ​​(x, y, z) to a camera installed on each face of a polyhedral, thereby generating a plurality of images having coordinate values ​​(x, y, z), storing them as 360-degree images of a polyhedral structure having coordinate values ​​(x, y, z) through a polyhedral analysis program, converting general 2D and 3D images into 360-degree images of a polyhedral structure having coordinate values ​​(x, y, z) through a polyhedral analysis program (26), and then projecting the images of the polyhedral structure having coordinate values ​​(x, y, z) of the polyhedral structure onto a sphere (3D) without modifying the images of the polyhedral structure, through a 360-degree polyhedral projector installed inside a sphere or hemisphere-shaped structure. This relates to a 360-degree image production and projection system using a polyhedron structure for projecting a 360-degree three-dimensional image having coordinate values ​​(x, y, z) created by a spherical triangulation method in a polyhedron analysis program through a plurality of LED image PCB modules having coordinate values ​​(x, y, z) installed inside or outside a sphere or hemisphere-shaped architectural structure, onto an LED image panel, which projects a 360-degree image on a vacuum image screen.

[0002] Referring to Fig. 1, to explain the prior art, a method of producing a 360-degree video using a fish-eye lens with a field of view (110) of up to 180 degrees and a video produced using multiple fish-eye lenses have more severe 360-degree video distortion than a normal camera lens (50 mm) with a field of view of 45 degrees.

[0003] In addition, various 360-degree videos are being produced through multiple cameras, and the videos are being produced in a three-dimensional (3D) format. However, most of these videos are stored in a two-dimensional (2D) format, and the directions of front, back, left, right, up, and down are artificially changed on a flat projector (cell phone, TV, etc.) to reproduce the three-dimensional (3D) 360-degree video in a two-dimensional (2D) format.

[0004] And, in the case of (b) in Fig. 2, when creating a three-dimensional (3D) image from a plurality of two-dimensional (2D) images, the 90-degree orthogonal method is a method of editing a two-dimensional (2D) image by dividing the image into a plurality of areas (① to ⑥) and projecting the image onto a spherical surface through a plurality of projection projectors (① to ⑥). When a flat image is projected onto a spherical surface, a distortion phenomenon occurs where the two images overlap each other, and this is a method of removing the overlapping image portion through complex computer operations, and most of the methods create a three-dimensional (3D) image model and convert it into a 360-degree three-dimensional (3D) image.

[0005] This is because, up to now, only the 90-degree orthogonal method (130) has been used to implement three-dimensional (3D) images.

[0006] Therefore, the present invention aims to provide a 360-degree image production and projection system using a new style polyhedral structure to solve the image distortion problem caused by the current 360-degree 3D image capturing method.

[0007] *Prior art literature*

[0008] (Patent Document 1) (Prior Document 1) Republic of Korea Patent Publication No. 10-1053819

[0009] Therefore, the present invention has been devised to solve the above-mentioned conventional problems.

[0010] The purpose of the present invention is to create a polyhedral camera that sets coordinate values ​​(x, y, z) to a camera installed on each face of a polyhedron, generate a plurality of images having coordinate values ​​(x, y, z), and store them as 360-degree images of a polyhedral structure having coordinate values ​​(x, y, z) through a polyhedral analysis program.

[0011] Another object of the present invention is to convert a general 2D or 3D image into a 360-degree image of a polyhedral structure having coordinate values ​​(x, y, z) through a polyhedral analysis program (26), and then to project a 360-degree image on a 360-degree vacuum image screen installed inside a sphere or hemisphere-shaped structure through a polyhedral structure projection 360-degree polyhedral projector that projects the image of the polyhedral structure having coordinate values ​​(x, y, z) of the polyhedral structure onto a sphere (3D) without modifying the image.

[0012] Another object of the present invention is to project a 360-degree three-dimensional image having coordinate values ​​(x, y, z) created by a spherical triangulation method in a polyhedron analysis program onto an LED image panel through a plurality of LED image PCB modules having coordinate values ​​(x, y, z) installed inside or outside a sphere or hemisphere-shaped architectural structure.

[0013] In order to achieve the problem that the present invention seeks to solve,

[0014] A 360-degree video production and projection system using a polyhedral structure according to one embodiment of the present invention is

[0015] A polyhedral camera (1000) capable of capturing omnidirectional images by setting various coordinate values ​​(x, y, z),

[0016] A storage device (2000) including a polyhedron analysis program (26) that stores image information including a unique number and coordinate values ​​(11, x, y, z), which are location information of the polyhedron camera unit (10), as a three-dimensional structured image, and analyzes and integrates the captured polyhedron structured image using a dedicated processor (25) to convert it into a complete 360-degree image,

[0018] A screen device (4000) comprising a vacuum image screen (400) or LED image panel (450) for outputting the 360-degree image provided above,

[0019] The problem of the present invention is solved by including a video tube structure (5000) including a 360-degree video tube (50) of a sphere (51) and a hemisphere (52).

[0020] The 360-degree video production and projection system using the polyhedral structure of the present invention provides the following remarkable effects.

[0021] By significantly reducing the distortion that occurs in 360-degree videos, anyone can enjoy real 360-degree videos from 360-degree video shooting to 360-degree video playback, and with the current lack of 360-degree video theaters, the development of the video industry and the film industry is expected.

[0022] Additionally, it will be possible to predict changes in the 3D video market, which is the main application of 360-degree video, and to implement more realistic videos in extreme sports, etc.

[0023] In addition, it has the effect of overcoming the shortcomings of fish-eye lenses used in meteorological observation and scientific and industrial fields, and has various applications in science, space industry, and general industry.

[0060] At this time, the shape of the camera (1000) of the polyhedral structure is characterized by including both the shapes of a sphere (51) and a hemisphere (52).

[0061] At this time, the vacuum image screen (400)

[0062] It is characterized by being a 360-degree video screen that creates a complete spherical shape inside a hemisphere (52) or inside a sphere (51).

[0063] Hereinafter, a detailed description will be given of an embodiment of a 360-degree image production and projection system using a polyhedral structure according to the present invention.

[0064] As shown in Fig. 5, the 360-degree image production and projection system using the polyhedral structure of the present invention is

[0065] A polyhedral camera (1000) capable of capturing omnidirectional images by setting various coordinate values ​​(x, y, z),

[0066] A storage device (2000) for creating a three-dimensional structure image using image information including a unique number and coordinate values ​​(11, x, y, z) which are location information of a polyhedron camera unit (10) using a polyhedron analysis program (26) programmed by a dedicated processor (25),

[0067] A projection polyhedral projector (31), which is a 360-degree projector having a polyhedral structure for transmitting a 360-degree image implemented and stored by a dedicated processor in the above storage device section, and a transmission device section (3000) including a general projection projector (39) and an LED image PCB module (38),

[0068] A vacuum image screen (400) for outputting 360-degree images provided by a polyhedral projector (31) and a general projection projector (39);

[0069] A screen device unit (4000) comprising an LED image Panel (450) for outputting a 360-degree image provided from an LED image PCB module (38);

[0070] It is characterized by comprising a video tube structure (5000) including a 360-degree video tube (50) of a sphere (51) and a hemisphere (52).

[0071] At this time, in the present invention, the basic technology for applying image projection to a screen for 360-degree image production is to apply geometric solids (3D) such as Platonic solids, Archimedean solids, Goldberg polyhedrons, and geodesic spheres, and the mathematical spherical triangulation method (see Fig. 4) that has already been verified by many scholars.

[0072] That is, the 360-degree video production and projection system using the polyhedral structure of the present invention is characterized by applying the spherical triangulation method.

[0073] The basic model (121-128) of image production (120) used in (a) of Fig. 2 is defined in such a way that the image area is a (rectangular) rectangle.

[0074] The present invention is characterized by a system that converts the image area structure into a polygonal shape, departing from the conventional (rectangular) image method, and analyzes the image using the 'spherical triangulation method' of triangles and hexagons in the image analysis method (131-136) of the 90-degree grid pattern of (b) in Fig. 2.

[0075] That is, the 360-degree grid projection (130) analysis method is applied.

[0076] Fig. 3 shows that each image information is divided into black (142) and white (141) areas where coordinate values ​​(x, y) are indicated in the 90-degree grid information (140) for creating a current 360-degree image.

[0077] This grid information (140) goes through an analysis process for 360-degree image implementation by projecting it onto a polyhedron (143). In the illustrated polyhedron (143), it is difficult to find a phenomenon in which the grid pattern projected onto the cylindrical polyhedron (①), sphere (②), and hexahedron (③) is distorted in the cylindrical polyhedron (①) and hexahedron (③), but it can be seen that the grid pattern projected onto the sphere (②) is distorted as it goes toward the poles.

[0078] That is, the grid pattern is not an efficient method for dividing a sphere.

[0079] The image distortion problem of 90-degree grid information (140) can be solved by first converting a sphere (151) based on the example regular icosahedron (265) into five spherical patterns (152) through a polyhedral sphere division method (150), and the division surface (153) divided into five patterns is further divided evenly into a number of triangles or hexagons (155), thereby minimizing image distortion in the polar region (154).

[0080] The present invention is characterized in that it excludes the grid-type (140) 'spherical quadrilateral division method' and produces a structural model of a polyhedral camera unit (10) based on the geometric polyhedral structure (Fig. 6) that is the basis of the 'spherical triangular division method (150)', thereby shooting a 360-degree three-dimensional (3D) image, and designates a unique region and a unique number as coordinate values ​​(x, y, z) (11) to the polyhedral camera unit (10), and stores a plurality of captured images in a polyhedral shape (3D) through a 'polyhedral analysis program (26)' by designating a unique region and a unique number as coordinate values ​​(x, y, z) (11).

[0081] And, it is characterized by collecting a number of two-dimensional (2D) images, dividing the images by using the 'spherical triangulation method' by specifying the coordinate values ​​(x, y, z) (11) of the unique region and unique number, converting them into a three-dimensional (3D) polyhedral shape, and playing them as three-dimensional (3D) images through the '360-degree image system'.

[0082] That is, the present invention provides a spherical triangulation technique for producing three-dimensional images.

[0083] In summary, the present invention provides the following technology.

[0084] That is, in order to solve the image distortion problem caused by the current 360-degree 3D video shooting method, a method for manufacturing a polyhedral camera (1000) that sets coordinate values ​​(x, y, z) on each face of a plurality of polyhedral camera parts (10), a method for storing a plurality of images having coordinate values ​​(x, y, z) set in the polyhedral camera parts (10) as 360-degree images of a polyhedral structure through a 360-degree image-only polyhedral analysis program (26), a method for converting other 2-dimensional (2D) and 3-dimensional (3D) images into 360-degree images of a polyhedral structure having coordinate values ​​(x, y, z) through a polyhedral analysis program (26), a method for manufacturing a 360-degree polyhedral projector (31) for projection of a polyhedral structure that projects an image of a polyhedral structure having coordinate values ​​(x, y, z) onto a sphere (3D) without modifying the image, 360-degree A method for manufacturing and installing a 360-degree vacuum video screen (400) installed inside a sphere or hemisphere-shaped structure for video implementation, a method for manufacturing and installing an LED video PCB module (38) having coordinate values ​​(x, y, z) for an LED video panel (450) installed inside or outside a sphere or hemisphere-shaped structure for video implementation, and a method for transmitting a spherically triangulated image together with coordinate values ​​(x, y, z) to an LED video panel (450) through a 360-degree polyhedron analysis program (26) for a 3D image can be provided.

[0085] Meanwhile, the polyhedral structure described in the present invention is

[0086] As shown in Fig. 6, it is characterized by including all structural forms of geometric polyhedra (3D) including 5 types of Platonic regular solids (260), 13 types of semi-regular solids (270), Goldberg polyhedra (280), and geodesic structures (290).

[0087] At this time, in order to solve the above-mentioned problem, the geometric polyhedron (3D) is included in the polyhedron analysis program (26) to determine the model of the polyhedron camera unit (10) and the model of the polyhedron projector (31), and is an important element for determining the LED image PCB module (38) of the Led image panel (450).

[0088] In addition, the system of the present invention uses a spherical triangular division method (151) using a geometric polyhedron (150), which is different from the spherical quadrilateral division method using a plurality of quadrilaterals in a 90-degree orthogonal method (140) that has an image distortion phenomenon (143) of FIG. 3, which is currently used when producing a 360-degree image, and minimizes image distortion when projecting an image onto the spherical surface of a 360-degree sphere (51).

[0089] When producing a 360-degree video, let's look at the interrelationships of polyhedron division methods (Table 1) in Fig. 6, which shows various methods of polygons that form a geometric polyhedron using the mathematical 'spherical triangulation method' that minimizes distortion, and an example of a specific implementation method.

[0090] Below, the components of the present invention will be described in more detail.

[0091] The camera (1000) of the above polyhedral structure,

[0092] It is characterized by being configured to include a plurality of polyhedral camera parts (10) that are uniformly arranged in all directions of 360 degrees, each of which is assigned a unique number and coordinate values ​​(11, x, y, z) as location information, and to provide 360-degree images and general images (19).

[0093] At this time, the storage device (2000)

[0094] A storage module A (21) that stores individual images including a unique number and coordinate values ​​(11, x, y, z), which are location information of the polyhedral camera unit (10);

[0095] A storage module B (22) for creating a three-dimensional structured image from image information including a unique number and coordinate values ​​(11, x, y, z), which are location information of the polyhedral camera unit (10);

[0096] It is characterized by including a polyhedron analysis program (26) that analyzes and integrates an image of a polyhedron structure captured using a dedicated processor (25) to convert it into a complete 360-degree image.

[0097] Specifically, FIG. 5 is a representative diagram to help understand a 360-degree video system, in which a camera (1000) has a polyhedral camera unit (10) equipped with a plurality of cameras for 360-degree video production, and the polyhedral camera unit (10) has unique coordinate values ​​(x, y, z) (11).

[0098] The image created in the polyhedral camera unit (10) includes a storage module A (21) that stores individual images including coordinate values ​​(x, y, z) (11), which are location information, and a storage module B (22) that stores 360-degree images, and a storage device unit (2000) that includes a dedicated processor (25) that contains a polyhedral analysis program (26) that creates a geometric polyhedral model using coordinate values ​​(x, y, z).

[0099] In addition, the transmission device unit (3000) includes a polyhedron projector (31), a general projection projector (39), and an LED image PCB module (38).

[0100] In addition, the screen device unit (4000) includes a 360-degree vacuum image screen (400) installed inside a sphere (51) or hemisphere (52) structure to project a 360-degree image, and an LED image panel (450) installed inside or outside the sphere (51) and inside or outside the hemisphere (52).

[0101] And, it is composed of a video tube structure (5000) including a video tube (50) that projects the created 360-degree video.

[0102] Therefore, the 360-degree image production and projection system using the polyhedron structure of the present invention sends a 360-degree image created by a polyhedron camera unit (10) with set coordinate values ​​(Fig. 16) to a polyhedron projector (31) through a polyhedron analysis program (26), and the 360-degree image is implemented through a 360-degree dedicated vacuum image screen (400).

[0103] A technology is provided in which a 360-degree video and a general video (19) created in a polyhedral camera section are converted into a polyhedral-shaped video (27) by a polyhedral analysis program (26) in a dedicated processor (25), and projected onto a dedicated vacuum video screen (400) and LED video panel (450) through a polyhedral projector (31) or a general projector (39).

[0104] In the present invention, a specific basic technology for solving the above-mentioned problem is to apply a theory for dividing a sphere composed of triangles and hexagons based on a polygonal division method, as illustrated in FIG. 6, and polyhedrons such as Platonic solids (260) [Platonic Solids, 500 BC], Archimedean solids (270) [Archimedean Solids, 400 BC], Goldberg solids (280) [Goldburg Solids, 1990 AD], and geodesic spheres (290) [Geodesic Dome - 1960 AD] can be used as polyhedron models used for spherical division.

[0105] The above polyhedron is characterized in that it is converted into a virtual polyhedron through the polyhedron analysis program (26) of FIG. 9 and built into a dedicated processor (25).

[0106] In addition, 360-degree video information captured by a polyhedral camera unit (10) with coordinate values ​​(x, y, z) is

[0107] A polyhedron-shaped model is created through a polyhedron analysis program (26), and the polyhedron-shaped 360-degree image model is reconstructed (NO) into a polyhedron 360-degree image to be sent to a transmission device (3000) or converted (YES) into a polyhedron image to be sent to a display device (04).

[0108] At this time, when the polyhedral structure of the polyhedral camera unit (10) and the polyhedral structure of the projection polyhedral projector (31) are the same or different, the polyhedral analysis program (26) is characterized by performing the role of finding the identity of the polyhedral camera unit (10) and the polyhedral projector (31) using a polyhedral triangulation method.

[0109] And, it is characterized by having a role of converting the image of the polyhedron camera unit (10) that found identity through the above polyhedron analysis program (26) into an image of a polyhedron structure suitable for the projection polyhedron projector (31).

[0110] As shown in Fig. 9, the polyhedron analysis program (26) is characterized by being pre-programmed into a dedicated processor (25) as a polyhedron structure in a three-dimensional (3D) form in a virtual space through a formula that mathematically defines the above-mentioned plurality of polyhedrons.

[0111] The polyhedron analysis program (26) is characterized by having the interrelationship of the polyhedron division method (Table 1) of Figure 6, which shows the interrelationship of the polyhedron, programmed in advance.

[0112] It is characterized by having a Platonic regular solid (260) and an Archimedean semi-regular solid (270) that is a truncated or trimmed version of a Platonic regular solid (260) pre-programmed.

[0113] It is characterized by a pre-programmed change in the structure of Plato's regular polyhedron (260) to Goldberg polyhedron (280).

[0114] It is characterized by having a pre-programmed triangulation gradient of Buckminster Fuller's geodesic sphere (290).

[0115] That is, the above polyhedron analysis program (26) is characterized by being designed to be able to analyze the interrelationships between polyhedrons.

[0116] As described above, the polyhedron analysis program (26) analyzes the interrelationship between polyhedrons for the purpose of analyzing the structure for manufacturing and installing an LED image PCB module (38) on a geodesic sphere in which polyhedron camera units (10) and polyhedron projectors (31) of different shapes are made or have already been made, and for the purpose of analyzing polyhedron images to be transmitted to the LED image PCB module (38).

[0117] This is because non-identical images between polyhedra are distorted and not properly compatible.

[0118] This interrelationship between polyhedra is also a program for mutual complementation of the polyhedra camera unit (10) and the polyhedra projector (31) within the 360-degree video system, and is characterized by providing a function for mutual complementation when converting a general image (320) into an image of a polyhedra structure and projecting it onto a 360-degree vacuum video screen (400) through the polyhedra projector (31), and transmitting the image that has passed through the polyhedra analysis program (26) to the LED video PCB module (38) for image information.

[0119] As shown in FIG. 6 in the present invention, a regular icosahedron (265), which is a Platonic solid (260) among polyhedra, is a representative example model of the present invention.

[0120] And, the development diagram (09) of FIG. 10 is composed of 20 identical triangles (numbers 0 to 19) on each face of a regular icosahedron, and the sphere of the regular icosahedron divided into 20 parts is a polyhedron that can be evenly divided and displayed in 360-degree directions. As a representative example of the implementation process of the present invention, a 360-degree video system will be described in detail.

[0121] This is not intended to limit the present invention to a specific embodiment of the regular icosahedron (265), but should be understood to include all types of polyhedrons of the present invention and all polyhedrons, modifications, equivalents or substitutes included in the spirit and technical scope of the present invention.

[0122] Looking specifically at FIG. 5, which describes a 360-degree video production and projection system using a polyhedral structure of the present invention, the present invention is characterized by being configured to include a polyhedral-structured camera (1000), a storage device unit (2000), a transmission device unit (3000), a screen device unit (4000), and an image tube structure unit (5000).

[0123] At this time, in the case of the camera (1000) of the polyhedral structure, preferably, 20 polyhedral camera parts (10) are uniformly arranged in all 360 degrees in the regular icosahedral (265) camera structure model, and each of the 20 polyhedral camera parts (10) is given a unique number and coordinate values ​​(x, y, z) (11) as location information.

[0124] The above 20 unique numbers and coordinate values ​​(x, y, z) (11) are the coordinate values ​​(x, y, z) (11) for each 360-degree direction of the polyhedron, and are the main image information for spatially configuring the face of a regular icosahedron in a virtual space through a polyhedron analysis program (26).

[0125] The virtual spatial location information having these coordinate values ​​(x, y, z) (11) is characterized as information that plays an important role in spherical segmentation in a polyhedral projector (31), a vacuum image screen (400), and an LED image panel (450).

[0126] To put it simply, it is a method of transmitting a video shot in a 360-degree direction in the direction in which it was shot.

[0127] And, the storage device unit (2000) includes a storage module A (21) that stores individual images including a unique number and coordinate values ​​(11, x, y, z), which are location information of the polyhedral camera unit (10);

[0128] It is characterized by including a storage module B (22) for creating image information including a unique number and coordinate values ​​(11, x, y, z) which are position information of a polyhedral camera unit (10) into a three-dimensional structured image.

[0129] That is, there is a storage module A (21) area that stores 20 individual images including coordinate values ​​(x, y, z (11)), which are location information of the camera, and a storage module B (22) area that creates 20 image information including coordinate values ​​(x, y, z) (11), which are location information of the camera, into a three-dimensional structured image, and the storage device section (2000) includes a server, a computer hard drive, an external hard drive, a USB memory, and everything else that can store images.

[0130] The image information in the storage module A (21) is 20 individual unique images, so each image is stored in a form that can be used according to the user's intention, and the user can extract only the necessary parts and use them through a dedicated processor (25).

[0131] In addition, storage module B (22) is a space for creating a 360-degree image, and collects image information having 20 location information, which are unique numbers and coordinate values ​​(x, y, z) (11), and programs it with a polyhedron analysis program (26) so that it can be implemented in a polyhedron projector (31) or a display device (40) and transmits it to a dedicated processor (25).

[0132] At this time, the storage module B (22) goes through a process of creating a 360-degree image in the form of an icosahedron in all 360 directions through a polyhedron analysis program (26).

[0133] One of the technical elements of the present invention for creating a 360-degree video system is that it is characterized by having a polyhedron analysis program (26) that divides the spatial area of ​​a 360-degree video into the number of polygons according to the type of geometric polyhedron by using a unique number and coordinate values ​​(x, y, z) assigned to each face in the structure of an icosahedron.

[0134] In addition, the present invention is characterized in that a dedicated processor (25) is mounted on the storage device (2000) that programs a three-dimensional polyhedron with a polyhedron analysis program (26) using a programming technology that has a unique number of the polyhedron camera part (10) and a unique coordinate value (x, y, z) (11) of the polyhedron camera part (10) while simultaneously taking an image with the polyhedron camera part (10), and the image is divided into 20 parts, which is the same number as the faces of an icosahedron, to more easily create a three-dimensional 360-degree image.

[0135] In addition, the above-mentioned transmission device unit (3000) is implemented in a dedicated processor (25) and performs the function of transmitting a 360-degree 3D image stored in a storage device unit, and includes a server or computer (300).

[0136] At this time, the above-mentioned transmission device unit (3000) is characterized by including a projection polyhedron projector (31), which is a 360-degree projector having a polyhedron structure for transmitting a 3D image implemented in a dedicated processor (25), a general projection projector (39), and an LED image PCB module (38).

[0137] Here, the structure of the polyhedral projector (31) is exemplified by a structure model identical to that of the icosahedral camera section (10) of the camera.

[0138] And, the above-mentioned screen device unit (4000) has a screen device area that displays a 360-degree 3D image transmitted from the transmission device unit (3000), and the screen device unit (4000) includes an image screen installed on the inside and outside walls of a hemispherical (52) or spherical (51) structure for viewing a 360-degree 3D image.

[0139] The present invention includes a 360-degree vacuum image screen (400) in the shape of a sphere (51) or hemisphere (52) installed inside a hemisphere (52) or sphere (51), which is a structure of a screen device (4000), and an LED image PCB module (38) and an LED image panel (450) installed inside or outside the hemisphere (52) or sphere (51).

[0140] Below, a 360-degree image production and projection system using a polyhedral structure according to an embodiment of the present invention will be described in detail with reference to drawings.

[0141] Figure 1 is a drawing showing a comparison of the angle of view (110) of a fish-eye lens and the angle of view (111) of a normal lens, and a distorted image of a 180-degree image (112) taken with a fish-eye lens, and is a drawing showing a distorted area when the image (112) of the fish-eye lens is interpreted with the Mercator projection, which is a 90-degree orthogonal method (113), and is an example showing the distortion phenomenon of a 360-degree image taken with a fish-eye lens.

[0142] That is, although it is possible to capture the entire 180-degree direction in one frame with a single fish-eye lens, it is easy to see that the image is distorted through the photo of the fish-eye lens (112) and the grid structure (113).

[0143] If you look closely at the photo (112) taken with a fish-eye lens, you can see that only the central part of the image is similar to the human eye, and the distortion of the image (112) increases as you go out from the center of the circle. As shown in FIG. 10, the image of the camera unit installed in a plurality of 360-degree directions has a difference in that the image distortion is reduced by the polyhedral camera unit (10) that can obtain an image in which the central or outer part is viewed in the same human eye.

[0144] In Fig. 2, (a) to (b) are reference diagrams for understanding the 360-degree spherical video production currently implemented by many users. In Fig. 2, (a) is a conceptual diagram (120) for creating a 360-degree 3D video by arranging up to 8 plane images (121 to 128) that have already been created, and the same method is used when creating a 360-degree 3D video from a general panoramic image (2D).

[0145] And, in Fig. 2, (b) is a photograph showing a programming technique for dividing a sphere into 6 parts (131 to 136) when projecting an image with 6 projectors (1 to 6) on the surface of a hemisphere (52). When projecting onto the sphere, the 90-degree grid structure of the program used is in the same form as the Mercator projection, and is a format for artificially deleting and correcting overlapping parts of square cells mosaicked on a computer.

[0146] Specially shot videos, such as those shot with a fish-eye lens, are also referred to as 360-degree videos, but in reality, these videos do not have a three-dimensional (3D) structure, but are stored in a two-dimensional (2D) format.

[0147] In other words, a video shot with a fish-eye lens or a 360-degree video shot with multiple cameras does not have three-dimensional (3D) coordinates (x, y, z) in itself, but is a two-dimensional video that is stored two-dimensionally and expressed three-dimensionally through artificial adjustment of the directions of front, back, left, right, up, and down.

[0148] The polyhedral camera unit (10) of the present invention for shooting a 360-degree video is characterized by a significant difference in that 20 cameras have coordinates (x, y, z) (11).

[0149] Figure 3 is an example of a 90-degree mosaic-shaped grid method (140) used in conventional video production and a spherical triangulation method applied to a polyhedral camera unit (10) having an icosahedral structure as exemplified in the present invention.

[0150] The white area (141) and black area (142) of the check pattern appearing in the existing grid method (140) have the planar coordinate values ​​(x, y) of the two-dimensional image, and expressing them by dividing them into the white area (141) and the black area (142) is a means for identifying them with the naked eye.

[0151] Looking at Figure 3, there are programs for image analysis, such as quadrilateral cell division (141 to 142) using a 90-degree orthogonal method (140) and triangular cell division (150) using a spherical triangulation method, and the multiple quadrilateral cell divisions (141 to 142) and multiple triangular cell divisions (151 to 155) created in this way are like the smallest unit of cells for creating a 360-degree image.

[0152] The difference is that while the square cell division (141 to 142) causes image distortion in the 360-degree image projected onto the sphere, the triangular cell division (150) of the spherical triangulation method causes almost no distortion in the 360-degree image projected onto the sphere.

[0153] The only way to solve the problem of the orthogonal form (140) program, in which the image is distorted when the rectangular cells (141-142) of the 90-degree orthogonal form (940) are applied to the sphere while overlapping the image, is the spherical triangulation method (150) of the polygon.

[0154] Therefore, in the present invention, the spherical triangulation method (150) is applied.

[0155] In Fig. 3, the grid method (140) is equally applied to various three-dimensional shapes (143). Although problems are hardly revealed in the three-dimensional planes of cylinders and hexahedrons, the grid method (140) displayed on the spherical surface of a sphere (②) of the three-dimensional shape (143) is considerably distorted as it moves toward the polar region. However, if a method of projecting an image onto the spherical surface of a sphere using the spherical triangulation method (150) is adopted, it can be seen that the image of the polar region (154) is identical to the images of other regions, and the distortion of the 360-degree image can be significantly reduced.

[0156] The spherical triangulation method (150), which is the basic principle of the present invention, can be applied to all polygons, but the quadrilateral division method (140) is only possible for quadrilaterals.

[0157] This is characterized by being designed to solve the limitations of a 90-degree orthogonal method program that interprets 360-degree images by using a polyhedron analysis program (26) to resolve image distortion of the orthogonal method (140) using the spherical triangulation method.

[0158] Figure 4 is an example diagram showing a method of dividing a sphere based on triangles using Class I, II, and III division methods (160), which are one of the spherical triangulation methods of a sphere.

[0159] In this way, spherical triangulation can be applied to polyhedrons based on hexagons, and spherical quadrilateral division can also be performed based on tetragons. The tetragon-based method is the same as the Mercator projection, which is a 90-degree orthogonal method.

[0160] Buckminster Fuller's Class I, II, and III spherical triangulation methods for geodesic spheres are frequently cited.

[0161] Figure 5 is a simplified conceptual diagram to help understand the 360-degree video production and projection system using the polyhedral structure of the present invention.

[0162] This example shows a process in which a 360-degree image of a polyhedron camera unit (10) is sent to a polyhedron projector (31) through a polyhedron analysis program (26), and the 360-degree image is implemented as a 360-degree image through a 360-degree dedicated vacuum image screen (400), and a general image is converted into a polyhedron-shaped image through a polyhedron analysis program (26), and is projected onto an LED image panel (450) through a 360-degree dedicated vacuum image screen (400) and an LED image PCB module (38), which is a component of the LED image panel (450), through a polyhedron projector (31) or a general projector (39).

[0163] Figure 6 is Table 1 showing the interrelationships of polyhedron division methods, and is a diagram showing the information of polyhedrons required in the process of producing and projecting 360-degree images using a polyhedron structure for converting the interrelationships between polyhedrons contained in a polyhedron analysis program (26) into polyhedrons so that they can be projected onto the spherical surface of a sphere through programming.

[0164] That is, starting from the Platonic solid (260) as the most basic form of spherical triangulation, it is a diagram of some of the changes to the Archimedean solid (270), some of the changes to the Goldberg solid (280), and some of the changes to the geodesic sphere (290).

[0165] Among the polygons (240) of Fig. 6, the tetragon and hexagon can create a plane, but cannot create a sphere by themselves, and the pentagon, heptagon, octagon, nonagon, and decagon cannot create a face or sphere by themselves.

[0166] Looking at the Archimedean polyhedron (270), a sphere must be created by combining other polygons, and the Goldberg polyhedron (280) can be divided into an infinite number of hexagons, but 12 pentagons must be included.

[0167] As can be seen from the geodesic sphere (290), this means that the most suitable polygon for spherical triangulation of a polyhedron that can divide all spherical surfaces infinitely is a triangle, and most mathematical polyhedron spherical triangulation methods are made up of triangles.

[0168] This is why a polyhedron analysis program (26) is needed to find a method of polyhedron mutual complementation through triangulation of these polyhedrons.

[0169] Looking at Figure 6, the five Platonic polyhedra (260) include the regular tetrahedron (261), the regular icosahedron (262), the regular dodecahedron (263), the regular octahedron (264), and the regular hexahedron (265). All five of the Platonic polyhedra (260) have faces that are arranged in their own unique directions in the 360-degree directions, so they can all be basic models for the polyhedron camera unit (10) and the polyhedron projector (31) that shoot 360-degree images.

[0170] In addition, the 13 Archimedean polyhedra (270) made by cutting and polishing the 5 regular solids of Plato (260) are structures in which multiple cameras can be installed, and the 13 Archimedean polyhedra (270) made of at least 2 polygons have all faces facing in all 360 degrees, so they can be used as structural models of a 360-degree polyhedron camera unit (10) and a polyhedron projector (31).

[0171] Both the Platonic solid (260) and the Archimedean solid (270) have unique coordinate values ​​(x, y, z) (11), and thus can be applied to both the 360-degree polyhedron camera unit (10) and the polyhedron projector (31) used in the present invention.

[0172] Figure 7 is an example of two structures of image cells for spherical division, in which spherical triangular division (254) and spherical hexagonal division (255) are performed through a polyhedron analysis program (26) installed on a dedicated processor (25).

[0173] The polyhedron analysis program (26) is characterized by being built-in based on the above-mentioned Platonic solids (260), Archimedean solids (270), Goldberg polyhedrons (280), and geodesic polyhedrons (290) through spherical triangulation (254) and spherical hexagonal division (255).

[0174] At this time, the polyhedron analysis program (26) plays a role in implementing a virtual 3D polyhedron image by interpreting it using the spherical division method.

[0175] When the 360-degree image composition of the three-dimensional structure is completed in the dedicated processor (25) containing the polyhedron analysis program (26) applied to the image of the polyhedron camera unit (10) of the example, the 360-degree image is sent to the server or computer (300) in the transmission device (30) area.

[0176] The 360-degree video sent to the server or computer (300) goes through a process of being transmitted to a polyhedron projector (31) made in the shape of a regular icosahedron (265), which is an example case of the present invention, or a general projection projector (39).

[0177] Figure 8 is a perspective view showing a 360-degree video tube (50) of a sphere (51) and a hemisphere (52) of a video tube structure (5000).

[0178] The structural shapes of the sphere (51) and hemisphere (52) are also structural models for installing a vacuum image screen (400) that projects a 360-degree image of the present invention.

[0179] In addition, it is a structural model for manufacturing and installing an LED video PCB module (38), which is a screen device for a 360-degree video, and is also a structural model of a spherical triangulation for transmitting a video to an LED video panel (450).

[0180] The installation of the vacuum image screen (400), the manufacturing and installation of the LED image PCB module (38), and the spherical triangular division of the image transmitted to the LED image panel (450) are described in detail through related drawings.

[0181] Figure 9 is an example diagram showing the relationship of a polyhedron that stores camera image information and is programmed through a dedicated processor (25).

[0182] Looking at Figure 9, there are multiple polygons in the polygon (240), but here, the triangulation method of a triangle (241), the triangulation method of a quadrilateral (242), the triangulation method of a pentagon (243), and the triangulation method of a hexagon (244) are given as examples.

[0183] All polygons can be divided into triangle structures, but not all polygons (240) can be subdivided into quadrilateral structures. When quadrilaterals are divided into triangle structures, more face divisions (242) are achieved.

[0184] This polygon triangulation method is applied to the basic polyhedron analysis in the polyhedron analysis program (26), and various polyhedrons (220) such as the Platonic solid (260), Archimedean solid (270), Goldberg solid (280), and geodesic sphere (290) are programmed as virtual polyhedrons through the polyhedron analysis program (26), and the interrelationships between polyhedrons in various methods (231 to 234) are programmed through the setting of the area for polyhedron correlation analysis (230).

[0185] The above various methods refer to, for example, polyhedron Dual (231), polyhedron continuous division (232), mutually complementary division method (233), polyhedron conversion method (234), etc.

[0186] Figure 10 is a perspective view of a regular icosahedron (265) development diagram (09) for explaining the present invention, a regular icosahedron (265) polyhedron camera unit (10) structural model for mounting multiple cameras, and a regular icosahedron (265) polyhedron projector (31) structural model.

[0187] The regular icosahedron (265) polyhedron camera unit (10) and the regular icosahedron (265) polyhedron projector (31) are characterized by having 20 identical triangular faces, as in the regular icosahedron (265) development diagram (09), with unique numbers set from 0 to 19 and coordinate values ​​(x, y, z) (11).

[0188] The structural model of the regular icosahedron (265) polyhedron camera part (10) and the regular icosahedron (265) polyhedron projector (31) shown as an example are characterized by the fact that the 20 cameras and projector directions for 360-degree video shooting and 360-degree video projection can be easily understood according to the arrangement form of the development diagram (09).

[0189] The polyhedral camera (10) structural model exemplified in Fig. 10 is a regular icosahedron (265) model in which multiple cameras are installed to obtain an image without distortion. If the regular icosahedron (265) model is applied to the polyhedral camera (10) structural model, 20 cameras can be installed, and if Archimedes' 32-hedron (12) is applied to the polyhedral camera (10) structural model, 32 cameras can be installed.

[0190] In addition, through the above-mentioned spherical triangulation method, 42-sided, 80-sided, 180-sided, and 360-sided spheres can be created, and the number of cameras installed increases by the number of sides, so that 360-degree images can be captured without distortion.

[0191] The present invention is characterized in that it applies a mathematical polyhedron formula called spherical triangulation so that each image has a unique coordinate value (x, y, z) (11), the arrangement of cameras is regular in all 360 degrees, and it is applied to triangulate a 360-degree sphere.

[0192] All 20 faces of the regular icosahedron polyhedron camera part (10) exemplified in Fig. 10 are in the form of identical triangles. When the polyhedron camera part is described through one triangle among the 20 faces, each triangle has a unique number (09) and unique coordinate values ​​(x, y, z) (11), and each face of the triangle is used as an independent polyhedron camera part (10) area. In order to mount more cameras, the triangle can be spherically triangulated in two stages (2V) into four triangles. (See Fig. 7)

[0193] This can be equipped with 80 more cameras, which is 4 times more, and can capture 360-degree images in 4 times more detail than the 20-sided polyhedral camera unit (10).

[0194] Additionally, if the triangle in the basic example is divided into three areas (3V) using the spherical triangulation method, 180 more cameras, which is 9 times more, can be installed.

[0195] This method of spherical triangulation (254) can infinitely expand the number of cameras and the area of ​​cells into which images are subdivided through mathematical rules.

[0196] This extension method means that cross-application is possible to the polyhedral camera unit (10), polyhedral projector (31), LED image PCB module (38), and even the basic cell structure of the image.

[0197] In addition, when looking at the perspective view of the polyhedron projector (31) made in the shape of an icosahedron according to the example of the present invention of FIG. 10, the shape of the polyhedron projector (31) is the same shape as the structural model of the polyhedron camera unit (10).

[0198] This is a polyhedral projector (31) made using a representative example method, and the morphological changes of the polyhedral projector (31) include all shapes such as Platonic solids (260), Archimedean solids (270), Goldberg solids (280), and geodesic polyhedrons (290) to which the sphere division method can be applied.

[0199] Referring to the development diagram (09) of a regular icosahedron (265), the polyhedron projector (31) has 20 faces (01 to 19) on which 20 projectors are installed, and the 20 faces have the same shape as the structural model of the polyhedron camera unit (10).

[0200] The polyhedron projector (31) is equipped with 20 projectors (01 to 19) with unique numbers (09), and it receives a 360-degree image created in the shape of an 20-sided sphere from a dedicated processor (25) through a computer and transmits it to a video screen.

[0201] The polyhedron projector (31) can immediately project onto a screen device (4000) such as a video screen without any process such as distortion or modification of the image. The 360-degree image already captured through the structural model of the polyhedron camera unit (10) has position information, i.e., coordinate values ​​(x, y, z) (11), as it passes through a dedicated processor (25). Therefore, the polyhedron projector (31) is designed to recognize the coordinate values ​​(x, y, z) (11) of the structural model of the polyhedron camera unit (10) as they are, so there is no problem in modifying or supplementing them.

[0202] In addition, when comparing the projection distance of the existing projection projector (39) when projecting an image by projecting from the outside to the opposite side of the vacuum image screen (400), the polyhedron projector (31) of the present invention has the effect of shortening the projection distance by half compared to the projection projector (39) because it projects from the center of the sphere to the vacuum image screen (400). This invention is characterized by a reduction in the economic burden and an increase in the utilization of space by reducing the specifications of the apparatus such as the projection projector (39) included in the polyhedron projector (31).

[0203] Additionally, when creating a 3D image in a dedicated processor (25), the shape of the polyhedron projector (31) can be determined according to the shape of the selected polyhedron.

[0204] For example, even if it is a 3D image divided into 20 faces produced with the structural model of the polyhedron camera unit (10) of the above embodiment, if a mathematical formula is used to make a regular icosahedron into an Archimedean 32-facet polyhedron by dividing the sphere by truncating the vertices of the regular icosahedron in a way that the vertices are truncated in a dedicated processor (25) equipped with a polyhedron analysis program (26), the 20 faces can be converted into a polyhedron with 32 faces in the dedicated processor (25), and by installing 32 cameras in the polyhedron projector (31), the 3D image divided into 20 areas captured with the structural model of the polyhedron camera unit (10) can be projected onto the video screen through the polyhedron projector (31) equipped with 32 projectors without distortion of the video screen.

[0205] Conversely, even if an image captured by 32 polyhedral cameras (10) is projected by 20 polyhedral projectors (31), the resulting value is the same.

[0206] This change is possible because the dedicated processor (25) equipped with the polyhedron analysis program (26) performs the process of polyhedron circulation and correction, and there is a mathematical logic programmed in advance to supplement it.

[0207] The polyhedron division method can complement the structural changes of the regular icosahedron and regular dodecahedron through the mathematical logic of duel in terms of the number of polyhedron camera parts (10) for filming and the number of polyhedron projectors (31), and the regular hexahedron and regular octahedron can also be cross-complemented through the mathematical logic of duel.

[0208] This is characterized by the ability to infinitely increase the number of polyhedral cameras (10) and polyhedral projectors (31) installed.

[0209] Accordingly, the present invention is characterized in that the shape of the polyhedral camera unit (10) and the polyhedral projector (31) illustrated in FIG. 10 include both the shape of a sphere (51) and a hemisphere (52).

[0210] FIG. 11 is a perspective view 1 showing the concept of making a vacuum image screen (400) used in the shape of a hemisphere (52) or a sphere (51), and describes in detail the method for making and installing the vacuum image screen (400) of the present invention among the screen device parts (4000).

[0211] A 360-degree video stored in a server or computer (300) is transmitted to a display device (4000) through a transmission device (3000). The display device (4000) can be a mobile phone, a flat-screen TV, or a flat-screen screen of a movie theater. The walls, floors, and ceilings of general buildings can also serve as screens.

[0212] The outside or inside of a hemisphere (52) or sphere (51) shaped structure of Fig. 8 can also be used as a screen device (40). An image can be projected on a general hemisphere (52) or sphere (51) structure without installing a video screen, and an image can be projected by manufacturing a video screen installed on the outside or inside of a hemisphere (52) or sphere (51).

[0213] At this time, the required video screen must be a video screen having the shape of a complete 360-degree sphere (51) or hemisphere (52) so that the 360-degree video produced in three dimensions can be projected without distortion.

[0214] The vacuum image screen (400) of the present invention is characterized by creating a 360-degree image screen that creates a complete spherical shape inside a hemisphere (52) or inside a sphere (51).

[0215] For example, there are currently various methods being used to create structures in the shape of a hemisphere (52) or a sphere (51), and a representative method is the air dome (53) structure operated by air injection (432) of Fig. 12, and there are also concrete structures and plastic structures.

[0216] First, looking at the difference between the vacuum image screen (400) of the present invention and the air dome (53) structure, the principle of the air dome (53) structure is a method of injecting air (432) like a balloon or an air balloon, which is the exact opposite concept to the vacuum image screen (400) structure of the present invention, which is a method of discharging air (407).

[0217] Even with the expansion of air like a hot air balloon, a screen like the vacuum image screen (400) of the present invention cannot be implemented, and even if a balloon injection method or an air injection type air dome (53) structure implements a 360-degree screen like the present invention, there is a significant difference in the principles and structures of the vacuum image screen (400) and the air dome (53) structure, such as the method of making and installing the structure. A typical air dome (53) structure functions as a structure in itself, but the vacuum image screen (400) of the present invention is installed by attaching and detaching to an existing structure (401) in a 'non-structural method', so there is a significant structural difference between the vacuum image screen (400) and the air dome (53).

[0218] Although various other dome-shaped structures are being built, they are all structures and thus are clearly different from the present invention, which is a non-structural form.

[0219] In particular, if the air injection type (432) and the air exhaust type (407) are installed in parallel, such as the vacuum image screen (400) of the present invention in the air dome (53) structure, the air dome (53) structure that withstands the air pressure of the air injection type (432) will become the biggest factor in causing imbalance and collapse of the air dome (53) structure due to the air exhaust type (407).

[0220] The air dome (53) is effective in dispersing air pressure (433) like a balloon by being inflatable (432), but it is blocked from further expansion by a thick wire on the outside due to excessive air injection, and the traces of the wire blocking expansion are replicated on the inside, making it impossible to implement a clear image film.

[0221] Although the air dome (53) structure can create a spherical or hemispherical image film through double film treatment, it is not compared with the air dome (53) structure because the concept and form are completely different from the present invention.

[0222] The vacuum image screen (400) is a 'non-structural method' that is applied to places such as geodesic dome structures or concrete structures that do not deform, and is structurally different from the air dome (53) structure in that it has a fundamental difference in concept.

[0223] That is, the vacuum image screen (400) of the present invention can be installed on structures such as a sphere (51) and a hemisphere (52), but it is not installed alone like a structure and is a non-structural form.

[0224] The equipment for projecting onto the vacuum image screen (400) can use an existing projection projector (39) or a dedicated projector (31) of the present invention.

[0225] Since the existing projection projector (39) has many users, the specification of the vacuum image screen (400) of the present invention does not discuss the usage of the existing projection projector (39).

[0226] However, it can be applied when an image of a polyhedral structure created by a dedicated processor (25) is to be projected.

[0227] The vacuum image screen (400) is an image screen that does not have an independent structure. In order to install the vacuum image screen (400), there must be an image tube (50) in the shape of a sphere (51) or hemisphere (52) in an architectural sense. The material of the architectural structure (401) can be made of wood, steel, concrete, etc. used in architectural structures.

[0228] In addition, in order to prevent distortion or deformation of the 360-degree video, the building structure (401) itself must be a structure that is not deformed by wind, snow, etc.

[0229] FIG. 12 is a perspective view 2 showing a structural concept for making a vacuum image screen (400) used in a hemispherical (42) or spherical (41) shape, and the manufacturing method and installation method of the vacuum image screen (400) of the present invention for implementing a 360-degree image are explained in detail through the attached drawings.

[0230] The video screen (50) in the shape of a sphere (51) or hemisphere (52) made of an architectural structure must be made of an architectural structure (401) that does not deform.

[0231] The vacuum image screen (400) is manufactured as a double structure including an air layer (405) in the middle in the form of an outer structure (403) and an inner structure (404). The material used for the outer structure (403) and the inner structure (404) may be a waterproof membrane structure or fabric used for tents or parachutes.

[0232] The vacuum image screen (400) has a plurality of connecting parts (406) that are fixed in close contact with the building structure (401), and the plurality of connecting parts (406) are attached to the outside of the outer structure (403) to the building structure (401), and the plurality of connecting parts (406) serve to connect the building structure (401) and the vacuum image screen (400).

[0233] A plurality of air pressure sensors (414) are attached inside an outer structure (403) to which a plurality of connecting parts (406) are attached, and the plurality of attached air pressure sensors (414) are a control device that checks the pressure of air required by a vacuum image screen (400) and prevents excessive exhaust of air.

[0234] The reason for controlling the air pressure is that, just as a balloon will burst if blown excessively, excessive exhaust from the vacuum image screen (400) can damage the membranes of the outer structure (403) and the inner structure (404) or distort the image.

[0235] And, the inner structure (404) is formed between the outer structure (403) and the inner space (405) of the air layer, and if there is only the inner space (405) of the air layer between the outer structure (403) and the inner structure (404), the outer structure (403) and the inner structure (404) can be separated from each other, so a plurality of connecting strings (410) of a certain length are attached between the outer structure (403) and the inner structure (404) to create an inner space (405) in which the outer structure (403) and the inner structure (404) are not separated.

[0236] In addition, the outer shell structure (403) and the inner shell structure (404) are manufactured as an integral body to completely block the flow of air, thereby maintaining a state in which the inner space (405) can be made into a vacuum state.

[0237] An air conditioning system (408) that creates a vacuum state in the internal space (405) is connected to the lower part of the vacuum image screen (400), and a pressure control controller (415) is mounted on the air conditioning system (408). The pressure control controller (415) is operated by pressure information of an air pressure sensor (414) installed in the internal space (405) and includes an intake section (407) and an exhaust section (409).

[0238] A corrugated pipe (416), which is an air passage connected to a vacuum image screen (400), is connected to the suction section (407).

[0239] Below, we will look specifically at how the vacuum image screen (400) operates through Fig. 12.

[0240] This description assumes that the vacuum image screen (400) is completely installed in a building structure (401) that is not deformed by external resistance through a number of connecting parts (406).

[0241] When power is supplied to the air conditioning system (408), the air conditioning system (408) starts operating, and the air conditioning system (408) that has started operating discharges air from the internal space (405) through the intake (407) to the exhaust (409).

[0242] As the air in the internal space (405) is partially released, the internal space (405) enters a vacuum state. As the vacuum state becomes stronger, shrinkage (412) of the outer structure (403) and shrinkage (411) of the inner structure (404) occur around the internal space (405). However, the outer structure (403) is firmly connected to the building structure (401) through a number of connecting parts (406), so that shrinkage (412) progresses to a certain extent toward the internal space (405) and then stops within the limit of the tensile strength of the material of the outer structure (403).

[0243] In addition, the inner structure (404), which corresponds to the actual video screen, contracts (411) toward the center of the inner space (405) to the limit of the vacuum state, but since the inner structure (404) is not fixed to the outside like the multiple connecting parts (406) of the outer structure (403), the contraction (411) is not the same as the contraction (411) of the outer structure (403), but the pressure of the vacuum state of the inner space (405) progresses as a uniform pressure (413) in the inner structure (404), and when the pressure of the inner space (405) reaches the data previously input to the pressure control controller (415), the air pressure sensor (414) installed in the inner space (405) transmits operation stop information to the air conditioning system (408) through the pressure control controller (415), and the air conditioning system (408) that has received the operation stop information stops operating.

[0244] Until the air conditioning system (408) stops, the inner structure (404) is maintained in a spherical or hemispherical shape with uniform pressure (413) that is optimal for projecting a 360-degree image.

[0245] The present invention is a vacuum image screen (400) characterized by a structure in which an outer shell structure (403) is fixed to a building structure (401), an air layer space (405) is formed next to the outer shell structure (403), and an inner shell structure (404) corresponding to an image screen is formed next to the air layer (705).

[0246] Figure 13 is a drawing showing the process in which a 360-degree image is sent as a spherical segmented image to an LED image PCB module (38) through a polyhedron analysis program (26), and the spherical segmented images are gathered to form a single 360-degree image projected onto an LED image panel (450).

[0247] Looking at it in detail, the 360-degree image production and projection system using the polyhedral structure of the present invention has a transmission device unit (3000), a screen device unit (4000), and a video tube structure unit (5000). The transmission device unit includes an LED video PCB module (38), the screen device unit includes a vacuum video screen (400) and an LED video panel (450), and the video tube structure unit includes a video tube (50) in the shape of a sphere (51) or hemisphere (52).

[0248] The LED image PCB module (38) of the above-mentioned transmission device unit (3000) is divided into images created by the polyhedron camera unit (10) or general individual images (19) using a spherical division method in a polyhedron analysis program (26), and the 360-degree images divided into spherical division methods are transmitted to the LED image panel (450) of the display unit through the LED image PCB module (38) installed in the entire 360-degree direction, and projected to the entire area.

[0249] At this time, the LED video panel (450) of the screen device is a structure installed on the outside or inside of the video tube (50) that projects a 360-degree video.

[0250] As illustrated in FIG. 14, the present invention describes a method for analyzing and manufacturing a shape of an LED image PCB module (38) installed inside or outside an image tube (50) in the shape of a sphere (51) or hemisphere (52) of an image tube structure, and has a feature of transmitting an image that has passed through a polyhedron analysis program (26) into a divided image on the LED image PCB module (38) and projecting the entire image on the LED image panel (450) of the display device.

[0251] The shape of the LED image PCB module (38) shown as an example is a triangle, and the LED image PCB module (38) is not limited to a triangle, but includes all polygons that can form a sphere surface.

[0252] FIG. 14 is a method of transmitting a 360-degree image to a Led image Panel (450) through a Led image PCB module (38) by analyzing (462) a sphere by a triangulation method (461) of a sphere (460) using an existing image segmentation method (495) in a grid shape (490), and not distorting or modifying the image, which differentiates the image analysis in a grid shape (490) from the triangulation method (461) of a sphere (460), and further, the invention is characterized by a difference in the method in which a plurality of image cells are arranged through the triangulation method (461) in the Led image PCB module (38).

[0253] Fig. 14 is a perspective view specifically explaining the difference between the grid-type image segmentation method (490) and the triangular segmentation method (460). In the manufacturing method of the Led image PCB module (38), various polygonal methods such as a square Led image PCB module (495), a triangular Led image PCB module (38), and a hexagonal Led image PCB module can be used.

[0254] However, the current technology is to convert the square LED image PCB module (495) into a diamond shape (496) because it cannot create a sphere (51) on its own.

[0255] The triangular LED image PCB module (38) is more efficient than the square LED image PCB module (495) in that it projects images on a sphere.

[0256] And, the method of dividing the sphere illustrated in Fig. 14 (490) is to divide a number of regions in the shape of equilateral triangles (492), and each region has the shape of a rhombus (493).

[0257] Although these diamonds are in the shape of squares, they are still used as a spherical segmentation method that causes image distortion in the square (494) of the image.

[0258] This method of dividing a rhombus is a structure based on the setting of an existing image of a (rectangular) rectangle (494), and the structure of the (rectangular) rectangle (494) area cannot avoid overlapping shapes (498) in the rhombus.

[0259] The overlapping diamond-shaped area (498) is a process of creating a single image by going through a complex computer modification process.

[0260] This result shows that the image segmentation of a square (494) is not the best choice, and proves the necessity of a triangle that is used equally in the configuration of a plane (463) and a sphere (462).

[0261] The sphere dividing method (460) of the present invention is a 360-degree image that is created by minimizing the overlapping portions of plane images, and the spherical triangular division (460) based on a regular icosahedron (265) means minimizing the distortion of the sphere through the division (462) of the sphere, which will be an opportunity to reduce the distortion of the image of the 360-degree image.

[0262] And, taking the regular icosahedron (265) as an example in Fig. 14, we will examine how the spherical triangulation (460) applied to a sphere and a sphere based on the triangle, which is the minimum unit of the regular icosahedron (265), determines the Led image PCB module (38).

[0263] Looking at the area (460) that describes the spherical triangulation, there is a regular icosahedron (265), and the regular icosahedron (265) is divided into 4 levels (4v) of triangles (461).

[0264] The shape of the unit triangle (461), which is one of the 20 identical triangles of the regular icosahedron (265), is marked in yellow, there is a sphere (462) showing how the shape of the unit triangle (461) is arranged on the spherical surface of the sphere, and there is a development diagram (463) of the regular icosahedron (265).

[0265] The green triangle (39) displayed on the 4v-divided surface of the regular icosahedron (265) represents the area of ​​the unit structure LED image PCB module (38), and this green triangle (39) represents the LED image PCB module (38), and the LED image PCB module (38) is further divided into 4v and subdivided into unit image cells in which LED lamps are placed.

[0266] The 20 identical faces of the regular icosahedron (265) can be divided into infinite triangles such as 2v, 3v, 4v, 5v, 6v, 7v, and 8v, and the infinitely divided triangles become a model of the Led image PCB module (38), and the model of the Led image PCB module (38) includes cells (380) of triangles that are infinitely divided.

[0267] This spherical triangulation means that the image can be divided into the smallest units and the divided image has minimal distortion.

[0268] The basic structure of the video hall (50) is divided into triangles through analysis, and the triangulation in architectural terms is achieved. The smallest triangle appearing on the sphere becomes the basis of the LED video PCB module (38), and a number of LED lamps are mounted inside the LED video PCB module (38).

[0269] LED lamp refers to a lamp in the form of RGB, and there is a regular arrangement rule for the arrangement or arrangement of these LED lamps, so it is no different from the arrangement rule for the LED lamps in square cells.

[0270] In other words, the arrangement of LED lamps in a square shape is only a rule from a fixed perspective, and there is no problem in installing or arranging LED lamps in a polygonal structure.

[0271] The Led image PCB module (38) of Fig. 14 is closely related to the polyhedron analysis program (26), and in order to determine the shape of the Led image PCB module (38) and transmit image information to the Led image PCB module (38), coordinate values ​​(x, y, z) (11), which are basic positional information of the image, are required.

[0272] The interconnectivity of these coordinate values ​​(x, y, z) (11) is an important element of the present invention, and is a function that is absolutely necessary in a 360-degree video system along with the role-specific functions of the invention described above.

[0273] Fig. 15 is a perspective view illustrating a spherical triangulation method for manufacturing and installing an LED image PCB module (38) of an LED image panel (450), which is a 360-degree image screen device, using an exemplified Platonic icosahedron (265).

[0274] Plato's regular icosahedron (265) is also a structural model of the LED image PCB module (38) and a structural model of spherical triangulation for transmitting images to the LED image panel (450).

[0275] Looking at it in detail, the illustrated (470) regular icosahedron (265) has 20 identical triangular faces, and one of the 20 triangular faces (471) is taken as an example.

[0276] The triangle (471) of the regular icosahedron (265) is the smallest unit in the regular icosahedron, and when each edge of the triangle (472), which is the smallest unit, is divided into two equal parts (473) and connected, four triangles (474) are created through a 2v division, and this division is called the spherical triangulation method.

[0277] If you divide an edge into three equal parts using the spherical triangulation method and divide it into nine triangles, it is called a 3v division, and if you divide an edge into four equal parts (475), you get 4v (476), which has 16 triangles. This has the characteristic that triangles can be divided infinitely.

[0278] The area (480) representing the polyhedron triangular division is an example diagram representing the step-by-step triangular division (1v to 9v).

[0279] For example, if we assume that the 8v(479) video tube (50) sphere (51) divided into 8 stages is newly built or there is an existing building, the new method (471 ~ 479) and the existing method (479 ~ 471) are the same when viewed in reverse, so if we explain them as one, the process will yield the same result.

[0280] This is a method of finding a structure model of an LED image PCB module (38) through spherical triangulation and applying it to a sphere.

[0281] Fig. 16 shows the spherical coordinate values ​​(x, y, z) (11) of a regular icosahedron (265), and can explain the position value (501) of a face (Face), the coordinate value (503) of the face, and the position value (502) of a vertex using spherical coordinates such as latitude and longitude.

[0282] Given two vertices at the North and South Poles (latitude ±90°), the remaining ten vertices are at latitude ± arctan 1 / 2 = ±26.57°.

[0283] These ten vertices are evenly spaced by longitude (at 36° intervals) and alternate between north and south latitudes.

[0284] This method assumes that the regular icosahedron (265) is an elongated pentagonal bipyramid with D5d dihedral symmetry.

[0285] That is, the regular icosahedron is formed by two congruent pentagonal pyramids connected by pentagonal antiprisms, and the coordinate values ​​(x, y, z) (11) of the regular icosahedron (265) are calculated using the polyhedron characteristics of geometry.

[0286] In summary, the 360-degree image production and projection system using the polyhedral structure of the present invention, in order to solve the above-mentioned problem, produces a polyhedral camera that sets coordinate values ​​(x, y, z) to a camera installed on each face of a polyhedron, generates a plurality of images having coordinate values ​​(x, y, z), saves them as 360-degree images of the polyhedral structure having coordinate values ​​(x, y, z) through a polyhedral analysis program, converts general 2D and 3D images into 360-degree images of the polyhedral structure having coordinate values ​​(x, y, z) through a polyhedral analysis program (26), and then projects the image of the polyhedral structure having coordinate values ​​(x, y, z) of the polyhedral structure onto a sphere (3D) without modifying the image of the polyhedral structure using a 360-degree polyhedral projector installed inside a sphere or hemisphere-shaped structure. It is a method of projecting a 360-degree image on a vacuum image screen, and a 360-degree 3D image with coordinate values ​​(x, y, z) created by a spherical triangulation method in a polyhedron analysis program is projected onto an LED image panel through a number of LED image PCB modules with coordinate values ​​(x, y, z) installed inside or outside a sphere or hemisphere-shaped architectural structure.

[0287] Meanwhile, below, we will specifically describe another type of embodiment.

[0288] That is, the 360-degree video production and projection system using the polyhedral structure of the present invention is,

[0289] A polyhedral camera (1000) capable of capturing omnidirectional images by setting various coordinate values ​​(x, y, z),

[0290] A storage device (2000) including a polyhedron analysis program (26) that stores image information including a unique number and coordinate values ​​(11, x, y, z), which are location information of the polyhedron camera unit (10), as a three-dimensional structured image, and analyzes and integrates the captured polyhedron structured image using a dedicated processor (25) to convert it into a complete 360-degree image,

[0291] A transmission device unit (3000) for transmitting a 360-degree image implemented and stored by a dedicated processor in the above storage device unit to a display device unit (4000),

[0292] A screen device (4000) comprising a vacuum image screen (400) or LED image panel (450) for outputting the 360-degree image provided above,

[0293] It is characterized by comprising a video tube structure (5000) including a 360-degree video tube (50) of a sphere (51) and a hemisphere (52).

[0294] Through the above configuration, the following advantages are provided.

[0295] That is, since a plurality of images with coordinate values ​​(x, y, z) are generated using a camera with a polyhedral structure, a 360-degree image with a polyhedral structure can be produced, and since the 360-degree image with coordinate values ​​(x, y, z) is saved through a polyhedral analysis program, a 360-degree image with a polyhedral structure can be projected through a 360-degree polyhedral projector with a polyhedral structure.

[0296] In terms of application, 360-degree videos of tourist attractions can be produced to provide tourists with vivid experiences, 360-degree videos of educational content can be produced to enhance students' understanding and immersion, and game backgrounds and characters can be expressed in 360-degree videos to enhance immersion.

[0297] Additionally, 360-degree videos can be used to enhance the effectiveness of advertising.

[0298] Additionally, as a polyhedral structure, the camera has a polyhedral structure (e.g., a cube, a dodecahedron, etc.), and one or more camera sensors are arranged on each face of the polyhedron.

[0299] This structure is designed to capture an omnidirectional, or 360-degree, view.

[0300] For coordinate value setting (x, y, z), each camera sensor is positioned according to specific coordinate values ​​(x, y, z), which determine the direction and range of the field of view captured by the camera.

[0301] For example, the x-axis may represent the horizontal direction, the y-axis may represent the vertical direction, and the z-axis may represent depth (or front-back direction).

[0302] As an omnidirectional video capture, each camera captures an image of the surrounding environment according to the set coordinate values, and the multiple images captured in this way are combined to create a complete 360-degree omnidirectional video.

[0303] When configured as above, it provides the following technical features.

[0304] As a continuity of the images, each camera has an overlapping field of view, providing natural continuity when combining the images.

[0305] For high resolution and detail, by using a polyhedral structure, each camera focuses on capturing a relatively narrow area, so the entire image can have high resolution and fine detail.

[0306] As a 3D spatial recognition system, by using x, y, z coordinates, this system can capture the depth and three-dimensional structure of a space beyond simple two-dimensional images.

[0307] Therefore, it can be effectively used in tourism, virtual reality, education, game development, advanced surveillance systems, etc., and is particularly suitable for providing users with a vivid 360-degree experience as if they were present at the scene.

[0308] This technology could also play a vital role in enhancing augmented reality (AR) and virtual reality (VR) experiences.

[0309] In addition, the above polyhedron analysis program is a software that plays a key role in analyzing and integrating captured images of polyhedron structures and converting them into complete 360-degree images. The main functions and features of this program are as follows.

[0310] As an image analysis program, the program individually analyzes the images captured from each polyhedral camera, and in the process, it determines the coordinate values ​​(x, y, z), directionality, resolution, and color information of each image.

[0311] As a video stitching, the analyzed videos are stitched together to create a single continuous 360-degree video. In this process, the borders between the videos are minimized and the color and lighting differences between different cameras are adjusted to create a natural overall video.

[0312] As a 3D modeling and mapping, it uses information about three-dimensional space to map images onto a 3D model, which allows the creation of 360-degree images with depth and spatiality similar to real environments.

[0313] In terms of technical features, it uses advanced image processing algorithms to seamlessly integrate images from various cameras, including image alignment, color and lighting correction, and distortion correction.

[0314] As a 3D spatial recognition algorithm, it recognizes the 3D spatial arrangement of an image and creates a more realistic 360-degree image based on this.

[0315] As for customizability, users can adjust the resolution, stitching degree, color adjustment, etc. of the video to their needs through the program's settings.

[0316] Providing a polyhedron analysis program like the above can be used to produce high-quality 360-degree videos for VR and AR experiences, and can be used in various video production fields such as movies, documentaries, and educational content, and can be used for live streaming of concerts, sporting events, conferences, etc. to provide the audience with a 360-degree omnidirectional viewing experience.

[0317] These polyhedral interpretation programs ultimately play a crucial role in providing users with a vivid viewing experience as if they were there.

[0318] Meanwhile, a polyhedral-structured projection 360-degree polyhedral projector designed to effectively project a converted 360-degree image is a projection device specifically designed to effectively project a converted 360-degree image, and projects a 360-degree image generated through a polyhedral-structured camera and an analysis program in a realistic and immersive manner.

[0319] As a polyhedral shape, the polyhedral projector has a polyhedral structure, which allows it to project images in multiple directions, and each face can be equipped with one or more high-resolution projector lenses, thereby projecting an overall 360-degree image.

[0320] For high-resolution projection, each projector lens is designed to project high-resolution images, providing sharp, detailed images.

[0321] In terms of viewing angle adjustment, the polyhedral projector can adjust various viewing angles, effectively fitting the image to surfaces of various sizes and shapes.

[0322] For synchronized projection, multiple projector lenses are synchronized with each other to produce a consistent overall image without overlapping portions of the image.

[0323] Through the above structure, the following functional features are provided.

[0324] First, as a realistic projection, the image is projected in all directions through the polyhedral structure, so the user can have a consistent viewing experience from any position.

[0325] Second, as it is widely compatible, it can be projected onto screens or surfaces of various shapes and sizes, making the system of the present invention suitable for a wide range of applications.

[0326] Third, as a purpose-specific adjustment, users can adjust the projection area, brightness, contrast, etc. to suit specific environments or needs.

[0327] Through the above configuration, the present invention can be applied to the following fields of application.

[0328] For education and training, it can be used for educational purposes to provide learners with an immersive experience in a 360-degree environment.

[0329] For entertainment, it provides an immersive viewing experience at performances, exhibitions, or amusement parks.

[0330] In the case of simulation, it allows for practice by recreating realistic environments such as pilot training and medical simulation.

[0331] As mentioned above, this polyhedral-structured projection 360-degree polyhedral projector plays a key role in providing users with a new viewing experience by projecting 360-degree images in a realistic and immersive manner.

[0332] And, the 360-degree vacuum image screen (400) in the shape of a sphere or hemisphere that displays a projected 360-degree image is a display medium specially designed to display a projected 360-degree image.

[0333] The above screen was invented to display images generated from a 360-degree polyhedral projector with a polyhedral structure in all directions.

[0334] Specifically, the screen has a spherical or hemispherical shape, either a perfect sphere or a hemispherical dome shape.

[0335] This format allows the video to be viewed from all 360 degrees, providing a consistent viewing experience regardless of the viewer's location.

[0336] As a high-definition surface, the screen's surface is made of a material that can clearly display high-definition images, ensuring high contrast and color reproducibility.

[0337] As a wide viewing angle, the screen provides a wide viewing angle and can display images without distortion from various angles.

[0338] As a vacuum structure, as the name vacuum image screen suggests, this screen can have a special vacuum structure, which helps to minimize the influence of the external environment and improve the quality of the image.

[0339] The functional features of the above vacuum image screen are as follows.

[0340] As an immersive viewing experience, spherical or hemispherical dome screens create an environment that completely immerses viewers in the image.

[0341] As a multi-purpose device, it can be used in various fields such as education, entertainment, exhibitions, and simulations.

[0342] As an environmental adaptability, the vacuum structure minimizes interference from external light or noise, allowing for high-quality images to be provided in any environment.

[0347] As described above, the 360-degree vacuum video screen (400) maximizes the experience through video by allowing the user to immerse himself in a complete 360-degree viewing environment.

[0348] That is, the 360-degree vacuum video screen (400) provides viewers with a unique way to enjoy videos without spatial restrictions.

[0349] Additionally, the vacuum image screen with a vacuum structure focuses on minimizing the influence of the external environment and maximizing image quality by introducing a technologically unique and innovative concept.

[0350] This technology will play a particularly important role in high-definition image display.

[0351] Specifically, it provides a blocking function from the external environment, and the vacuum structure completely blocks the inside of the screen from the external environment.

[0352] This means there is no or very little air or other gases inside the screen, which minimizes the impact of factors such as external light sources or noise on image quality.

[0353] It provides image contrast and color enhancement functions, and because optical distortion and reflection are greatly reduced in a vacuum, the image contrast and color reproducibility are improved.

[0354] This can provide clearer and more vivid images.

[0355] It provides temperature control, and its vacuum structure also helps maintain a stable internal temperature.

[0356] This plays a vital role in preventing overheating problems that affect the performance of video display devices.

[0357] Additionally, as technical features, it provides the following features:

[0358] First, it can be used stably for a long period of time. Specifically, because the influence of external factors is reduced, the screen can maintain stable performance over a long period of time.

[0359] Second, ease of maintenance is possible. Specifically, the vacuum structure prevents contamination or dust accumulation inside the screen, making maintenance easy and cost-effective.

[0360] Third, it provides adaptability and versatility, making it suitable for use in a variety of environments and can be utilized in a variety of places, including movie theaters, museums, and educational facilities.

[0361] Additionally, as an application field, the following applications are possible.

[0362] This technology can be particularly valuable in environments that require high-definition viewing environments, such as virtual reality, simulations, and high-definition video display.

[0363] It can be used in extreme environments, for example, it can maintain stable image quality even under bright lighting or extreme temperature conditions.

[0364] Therefore, vacuum image screens will play a crucial role in environments where image quality and viewing experience are paramount, as they provide viewers with a more immersive experience and offer potential for use in a variety of applications.

[0365] Below, a camera with a polyhedral structure that can capture an omnidirectional image by setting various coordinate values ​​(x, y, z) is used to take pictures, and the resulting pictures are saved. An example of the saved format is presented, and a data sample is provided as an example to explain.

[0366] Specifically, data obtained from a polyhedral camera that captures omnidirectional images by setting various coordinate values ​​(x, y, z) has complex and multidimensional characteristics.

[0367] The format for storing such data must include the image data obtained from each camera of the polyhedral structure and the spatial coordinates of the data. Below, a simple data sample is presented along with an example of such data storage format.

[0390] }

[0391] As mentioned above, the data for each camera may include a unique ID, spatial coordinates, image data, and capture time.

[0396] Each of the above cameras has a unique identifier and spatial coordinate information, and the captured image data is stored in a structured data format (JSON or XML).

[0397] Includes a polyhedron analysis program that analyzes and integrates captured image data to convert it into a full 360-degree image.

[0398] The above polyhedron analysis program is characterized by performing image stitching, 3D modeling, mapping, and color and lighting correction based on data obtained from each camera.

[0399] It includes a projection 360-degree polyhedral projector with a polyhedral structure designed to effectively project a converted 360-degree image.

[0400] Each projector lens included in the above polyhedral projector effectively projects a high-resolution image and is characterized by providing a consistent image in all directions through a polyhedral shape.
