Description

[Technical Field]

[0001] This application relates to systems and methods for creating two-dimensional (2D) or three-dimensional (3D) holography (e.g., 2D or 3D holographic characters or holograms). [Background technology]

[0002] Rides and attractions often attempt to bring characters from the screen (e.g., animation, movies, television, video games, etc.) into the real world. Some solutions use animatronics or other physical models that are physically placed in the environment (e.g., near the ride's vehicles or tracks). However, the animatronics or physical models must be moved or positioned to prevent contact with the physical animatronics or models. For example, careful controls must be used to prevent unwanted contact between people and ride vehicles and the physical animatronics or models. Such systems can require large spaces, large capital inputs, and high costs. Animated figures can also require large and / or complex infrastructure and safety systems to prevent unwanted contact.

[0003] Therefore, there is a need for systems and methods for creating holographic characters (e.g., holograms) (e.g., optically placing 2D or 3D characters in a real-world environment) that address the above-mentioned problems or at least offer alternatives to existing solutions. Summary of the Invention [Means for solving the problem]

[0020] Optionally, each lens of the pair of identical lenses is a Fresnel lens.

[0021] In addition to the exemplary aspects and embodiments described above, further aspects and embodiments will become apparent by reference to the drawings and by study of the following descriptions. [Brief explanation of the drawings]

[0022] [Figure 1] FIG. 1 shows a perspective view of an exemplary system for creating a hologram. [Figure 2] 2 shows a top elevation view of the system of FIG. 1. [Figure 3] FIG. 1 shows a front elevation view of the system, showing the guest's point of view (POV). [Figure 4] 2 illustrates an exemplary attraction implementing the system of FIG. 1. [Figure 5] 1 illustrates another exemplary system for creating a hologram. DETAILED DESCRIPTION OF THE INVENTION

[0023] The entertainment industry has created many characters that exist only on the screen (e.g., in animation, movies, video games, etc.). When creating rides or attractions based on such characters, it may be necessary to bring these characters into the real world. In one example, it may be necessary to place animated characters very close to the ride path (e.g., in front of the ride vehicle on the ride path) or in other immersive environments.

[0024] As an example, the system optically places a 2D or 3D character or video of a character (e.g., a 2D or 3D holographic character or hologram) in a real-world environment (e.g., as part of an immersive experience). For example, a 3D hologram may be generated at any location within or along the ride path (e.g., in front of the ride vehicle, or floating at a desired location, or in other such manner). By creating a 2D or 3D character through an optical system, the character is created without the need for a physical character at all (e.g., without the need to fly, move, or place any physical elements in the environment).

[0025] In the examples described herein, an image (e.g., a 2D or 3D hologram) is optically created to appear clearly at a desired location (e.g., a desired distance from a wall, e.g., from just in front to far in front of the wall). The technology, infrastructure, or system used to create the hologram may be hidden from view, for example, hidden in plain sight behind a scrim or other barrier. Depending on the properties of the system, the hologram may be viewable in bright as well as dimly lit environments.

[0026] For example, a display fitted with a high-resolution lens and placed in front of a sheer-printed scrim or other optical barrier can cause a character image or video image to float away from a wall or object, appearing like a hologram to a viewer positioned in front of the assembly. The system can be adjusted to vary the floating distance as needed. The display (e.g., the light emitted from the display) can be adjusted to change the properties of the hologram. For example, the light can be adjusted to make the hologram appear opaque (e.g., completely opaque), move the hologram, change color, or produce other effects. The system may be scalable, e.g., depending on the scale and / or application. For example, the system can be designed to work in small-scale installations or applications (e.g., one-foot scale) or large-scale installations or applications (e.g., for an 8-foot-high wall application).

[0027] In keeping with the above overview, FIGS. 1-3 show various views of an exemplary system 100 for creating holograms. FIG. 1 shows a perspective view of system 100. FIG. 2 shows a top elevation view of system 100. FIG. 3 shows a front elevation view of system 100, illustrating a guest or viewer's point of view (POV). System 100 may be configured to create a perceived image 102 (e.g., a hologram) in 3D space ("perceived image," hereinafter referred to as "image" for convenience, is not intended to be limiting, and is intended to encompass both 2D and 3D representations of characters, scenes, or objects). The image 102 created by system 100 may represent a physical object, a thematic element, or a desired character (e.g., from an animation, movie, television program, video game, etc.). The image 102 may be perceived at any position within 3D space. For example, the image 102 may appear to float (i.e., the image is perceived as a floating image or as floating above a particular surface or location). This is because the image 102 appears to be detached from the wall or floor (e.g., appears to be floating in the air, or appears to be located away from the screen, or appears to be so in other ways). The image 102 may be 2D or 3D, depending on the application. In this way, 2D or 3D characters or objects can be created in space (e.g., in a ride or attraction for an immersive environment) without requiring the physical placement of an actual object at that location in space. By way of example, the image 102 may be considered a hologram.

[0028] The system 100 may include a lens stack 106, an image surface 108, and a scrim layer 110. The lens stack 106 may include multiple lenses (e.g., a lens pair) arranged or stacked together. For example, the lens stack 106 may include a first lens 118 and a second lens 120. Each lens (e.g., of a lens pair) may be identical. For example, each lens may be a Fresnel lens (e.g., a planar Fresnel lens, a plano-convex Fresnel lens, a spot Fresnel lens, a spherical Fresnel lens, a solar cooking Fresnel lens, a photovoltaic Fresnel lens, etc.) that is identical or nearly identical in size and configuration (e.g., same focal length, resolution, size, etc.). A Fresnel lens may be configured to concentrate light, focusing light rays that would normally be scattered onto a focal plane or image point (e.g., defined by a focal length). For example, a Fresnel lens may include specially designed textures (e.g., ridges and grooves) that collect, direct, or otherwise focus scattered light onto a focal plane or image point. In an example implementation of a plano-convex Fresnel lens (or other Fresnel lens), light may be focused to a point, thereby reducing the distance required between the image plane 108 and the lens stack 106, for example, to package the image source closer to the lens stack 106 and make the system 100 more compact. By way of example, each of the first lens 118 and the second lens may include a flat or glossy surface and an opposing surface having ridges and grooves (or other textures). In such an example, the first lens 118 and the second lens may be stacked facing each other, e.g., with their respective textures (e.g., texture to texture, ridge peak to ridge peak) facing each other, and the flat / glossy surfaces may face outward.

[0029] The lenses may be held in alignment. For example, the first lens 118 and the second lens may be held so that their centers are aligned (e.g., so that the ridges and grooves of the first and second lenses 118, 120 are aligned). Depending on the application, the first and second lenses 118, 120 may or may not be bonded to one another to maintain the spacing and alignment between them. Along those lines, the first and second lenses 118, 120 may be held in alignment in various ways, such as with mechanical fasteners, adhesives, being framed together, being secured separately, etc. As an example, an adhesive may be disposed between the pair of lenses. In such an example, the adhesive may have the same refractive index as air (or another refractive index, if desired) and may fill all or nearly all of the gap between the first and second lenses 118, 120.

[0030] 2, the lens stack 106 may include a first side 124 and a second side 126 opposite the first side 124. The image surface 108 may be disposed on the first side 124 of the lens stack 106, and the scrim layer 110 may be disposed on the second side 126 of the lens stack 106 (e.g., as described below).

[0031] The image plane 108 may be defined by an image source, such as an image generator, display, monitor, projector, etc. For example, the image source may be a liquid crystal display (LCD) or light emitting diode (LED) display (e.g., organic LED, LED panel, etc.) that defines the image plane 108. The image plane 108 may be defined by a high contrast imaging surface (e.g., of the image source). By way of example, the image plane 108 may be defined by one or more displays that are low brightness or dim (e.g., 500 nits, less than 500 nits), for example, to produce a desired effect on the image 102 (e.g., a transparent, ghostly, or atmospheric, floating video effect). Alternatively, the image plane 108 may be defined by one or more displays with high brightness (e.g., greater than 1500 nits, up to 4000 nits, greater than 4000 nits), for example, to generate the image 102 with a different effect (e.g., opaque (e.g., completely opaque)). The high brightness one or more displays may also allow the image 102 to be generated in daylight or high brightness environments (i.e., the present disclosure is not limited to dimly lit or subdued lighting environments). By way of example, the displays may have a high black level to increase contrast. In examples where the image source is a projector, the projector, whether rear-projection or front-projection, may project onto the image plane (i.e., image plane 108).

[0032] Referring to FIG. 1 , an image source may create a generated image 128 on an image plane 108. As shown, the generated image 128 may be upside down, taking into account that the lens stack 106 inverts the image. For example, the generated image 128 may be inverted as it passes through the lens stack 106 (e.g., light from the image source (e.g., the generated image 128) first passes through a first lens and then a second lens) and projected as the perceived image. The generated image 128 may be an image (e.g., an image, a video) created by an image source (e.g., from media content) at the image plane 108. In some examples, the generated image 128 may be created live. For example, a real actor, puppet, or animatronic may be illuminated. In some examples, one or more physical objects may be illuminated to create the generated image 128.

[0033] 1-2 , image plane 108 (image source) may be spaced (distanced) from lens stack 106 (e.g., on first side 124 of lens stack 106). For example, image plane 108 may be located at a first distance 132 from lens stack 106. By way of example, first distance 132 may be the same as or approximately the same as the size of lens stack 106. For example, if lens stack 106 (or an individual lens in lens stack 106) is 1 m by 1 m in size, first distance 132 may be 1 m or approximately 1 m.

[0034] A scrim layer 110 (sometimes simply referred to as scrim) may be disposed on the second side 126 of the lens stack 106. For example, the scrim layer 110 may be disposed proximate to the lens stack 106, such as directly adjacent to the lens stack 106, at the lens stack 106, or in contact with the lens stack 106, or in other such manner. The scrim layer 110 does not need to contact the lenses, although such an example may provide greater depth to the image 102. The scrim layer 110 may be a flexible material, such as a fabric or cloth with an open weave, to allow some light to pass through (e.g., to diffuse the light and / or reduce the brightness of the light). By way of example, the scrim layer 110 may be formed of chiffon or another sheer fabric.

[0035] The scrim layer 110 may be used to conceal the lens stack 106 and the image surface 108. For example, the scrim layer 110 may be formed of a sheer or sheer-like material that allows backlight (e.g., from the lens stack 106) to shine through the scrim layer and is somewhat opaque when front-lit (e.g., to hide the lens stack 106 and the image surface 108 behind the scrim layer 110). For example, the scrim layer 110 may appear solid (e.g., like a solid piece of fabric) when front-lit, while appearing translucent when back-lit. In such an example, front lighting (not shown) may be provided to illuminate or glare the front surface of the scrim layer 110. Front lighting allows the front of scrim layer 110 (e.g., the texture and presence of scrim layer 110) to remain visible, which aids in generating image 102 (e.g., helping image 102 appear 3D). By way of example, front lighting should be only half as bright as the image source behind scrim layer 110. For example, if the image source has a brightness of 2000 nits, then the brightness of the front lighting measured at scrim layer 110 should be 1000 nits or less.

[0036] The scrim layer 110 may be flat or non-flat, and may include, for example, texture, ripples, or curvatures when draped in front of the lens stack 106. By way of example, the scrim layer 110 may include a design or pattern, such as a design or pattern that conceals or blends the scrim layer 110 into its surroundings. For example, the scrim layer 110 may be patterned, designed, or colored to match or nearly match the surrounding walls or ride set within the ride environment to further conceal or obscure the operation of the system 100 from the view of the ride vehicle or rider. By way of example, the scrim layer 110 may define one or more walls of the ride set itself, in which case the scrim layer 110 appears to the rider or guest like an ordinary wall (e.g., nothing out of the ordinary). The system 100 is not dependent on the size of the scrim layer 110, so long as the scrim layer 110 conceals the lens stack 106 and the image plane 108 from view. By way of example, the design or pattern of scrim layer 110 may be eye-catching while still concealing lens stack 106 and image plane 108. By way of example, the shape of scrim layer 110 (e.g., wavy or curved when draped) may aid in obscuration. Scrim layer 110 may include a digital print or may be hand-painted, depending on the application.

[0037] By way of example, the system 100 may include an optional filter layer 134 between the lens stack 106 and the scrim layer 110. The filter layer 134 may adjust or modify (e.g., darken or modify) the light entering from the lens stack 106. By way of example, the filter layer 134 may be a neutral density (ND) filter or layer that reduces the amount of light that passes through the scrim layer 110. For example, the ND filter may block between about 20% and about 80% of the light (e.g., about 60% of the light, a 0.6 filter, etc.). By way of example, the filter layer 134 may increase the depth of the image 102 (e.g., to create or enhance a 3D effect), enhance contrast, and / or otherwise improve image quality.

[0038] As an example, the system 100 may include an optional vignette or mask 136 ("vignette or mask" will be referred to hereinafter as "mask" for convenience and is not intended to be limited to any particular structure or feature). The mask 136 may be disposed between the filter layer 134 and the scrim layer 110. The mask 136 may be a transparent substrate (e.g., Plexiglas). The mask 136 may have printed or painted edges that conceal the edges of the lens stack 106, for example, black printed or painted edges that conceal the square hard edges of the lens stack 106 in front of the lens stack 106. Additionally or alternatively, the mask 136 may provide artistic effect or intent. For example, the mask 136 may be useful for creating or adjusting the image 102 (e.g., covering or altering selected portions of the image 128 or adding one or more elements to the image 102). The mask 136 may be a separate layer or may be at least partially defined by the filter layer 134 .

[0039] The lens stack 106, scrim layer 110, optional filter layer 134, and optional mask XX can create the image 102. For example, the lens stack 106 can project an image from an image plane 108 in front of the lens stack 106 (e.g., at a focal distance from the lens stack 106). The scrim layer 110 provides a plane or surface on which the viewer focuses and creates a perception of distance from the image 102. For example, the scrim layer 110 can create the impression that the image 102 is floating in front of the scrim layer 110 (e.g., the image 102 appears in the void or in front of an area of ​​a wall defined by the scrim layer 110).

[0040] In some examples, additional elements may be provided to "ground" the image 102. For example, a platform (not shown) may be placed under the image 102 to aid in visualization of the projection. By way of example, the platform may include a diffusely reflective surface. In such examples, a shadow or reflection of the image 102 may be seen on the diffusely reflective surface. Another element to "ground" the image may be a physical support and / or a person standing next to the image 102.

[0041] The visibility of the image 102 may be defined by the size or configuration of the lens stack 106. For example, the lens stack 106 may define the field of view (FOV) at which the image 102 is viewed by a viewer (e.g., from a guest's POV). By way of example, a larger lens stack 106 provides a larger or wider FOV, and vice versa. A wider FOV allows the image 102 to be viewed from a wider range of angles and distances, for example, allowing the image 102 to be viewed by multiple guests in different locations. Without a wide FOV, the image 102 may appear strange or distorted unless viewed from a specific angle or a limited range of angles.

[0042] As an example, the image 102 is created on the second side 126 of the lens stack 106 (e.g., created a second distance 138 away from the lens stack 106). The second distance 138 may depend on the specifications of the lens stack 106 and the distance from the lens stack 106 to the image plane 108 (surface). For example, the second distance 138 may be the same as the first distance 132. In this manner, the image plane 108 may be located on the first side 124 of the lens stack 106 at a distance from the lens stack 106, and the image 102 is created on the second side 126 of the lens stack 106 at the same distance from the lens stack 106. The second distance 138 may be the same as or approximately the same as the size of the lens stack 106. For example, if the size of the lens stack 106 (or an individual lens in the lens stack 106) is 1 m by 1 m, the second distance 138 may be 1 m or approximately 1 m.

[0043] 4 illustrates an example attraction 400 implementing system 100. Attraction 400 may include a show set 402 (e.g., positioned along a track 408) and one or more ride vehicles 404. In such an example, system 100 may be used to project image 102 along the track 408 (e.g., in front of or near the ride vehicles 404). A scrim layer 110 may be incorporated into show set 402, thereby defining a surface of show set 402, such as positioned within a viewing path of show set 402.

[0044] 5 illustrates another implementation of system 100 for creating holograms. In the example of FIG. 5, system 100 includes a bounce mirror 500 between image plane 108 (image source) and lens stack 106 to fold the optical path from image plane 108 to lens stack 106. In such an example, the optical path may define a distance (e.g., first distance 132) from lens stack 106 to image plane 108. Bounce mirror 500 may be oriented based on the positional arrangement of image source and lens stack 106. For example, bounce mirror 500 may be positioned at 45 degrees relative to the image source and lens stack 106, although other configurations are envisioned to package system 100 into other footprints (e.g., based on other configurations of attraction 400). Although not shown, in the implementation shown in FIG. 5, a scrim layer 110 and a filter layer 134 may also be used in front of the lens stack 106, for example, to hide the lens stack 106 from view and improve the image quality of the image 102.

[0045] System 100 may be used to implement a method or process for creating a perceived image or hologram in space (e.g., in the environment of a ride or attraction). For example, an image (e.g., generated image 128) may be created at image plane 108, e.g., by an image source (e.g., an LCD, LED display, projector, etc.). Image plane 108 may be located a distance away from lens stack 106, e.g., a focal length away from lens stack 106.

[0046] Light from the generated image 128 may pass to the lens stack 106. For example, the light from the generated image 128 may first pass to the first lens 118 of the lens stack 106 and then to the second lens 120 of the lens stack 106. After passing through the lens stack 106, the light may pass through the scrim layer 110. The scrim layer 110 may modify one or more properties of the light, for example, may diffuse the light and / or reduce the brightness of the light.

[0047] Light projected through the lens stack 106 passes through the scrim layer 110 and may then be collected to create the image 102, for example, at an imaging plane that is a distance away from the lens stack 106 (e.g., the focal length away from the lens stack 106). The image 102 may be perceived anywhere in 3D space, for example, within the ride environment, in front of the ride vehicle 404, on the tracks 408, or elsewhere (e.g., as part of an immersive experience).
