[0002] This application claims priority to U.S. Provisional Application No. 63 / 877,437, filed September 8, 2025, the contents of which are incorporated herein by reference. Technical Field

[0003] This disclosure relates to scanning systems for three-dimensional (3D) and 4D data acquisition, and more specifically to modular, portable spherical systems designed for high-resolution imaging of physical objects, including humans, animals, and inanimate objects. The system is suitable for a variety of scanning purposes, such as digital avatars, artificial intelligence (AI) datasets, volumetric video, photogrammetry, and accurate reconstruction of physical forms in virtual, augmented, or mixed reality environments. Background Technology

[0004] Scanning systems are often stationary, bulky, and difficult to transport. Their rigid, non-modular construction can require significant time and labor to assemble, calibrate, or reposition, typically taking days to weeks to fully assemble or move between locations. This makes them impractical for dynamic production environments, mobile scanning applications, or field-based data collection.

[0005] Additionally, in some cases, their fixed nature limits the use of controlled facilities, thereby reducing the flexibility of capturing volumetric data during on-site shooting or the flexibility for mobile applications such as those mounted inside trucks or vans. These systems may include custom integrations of cameras, lighting, synchronization hardware, and support structures, and once deployed, they have limited reusability or scalability. Summary of the Invention

[0006] This disclosure describes a compact, modular, and reconfigurable spherical scanning system that maintains consistent geometric accuracy while allowing for rapid deployment, disassembly, and transport.

[0038] This disclosure describes a movable scanning system (“rack”) with a spherical housing formed from modular structural rack segments, which may be geodetic or otherwise shaped. The movable scanning system may include a panel mounted to a base rail and can be assembled and disassembled for transport.

[0039] In some examples, each modular rack segment of the spherical structure can be independent, housing its own network interface, power distribution system, local storage unit, and camera triggering mechanism. This distributed architecture enables scalable deployment across all rack segments, simplified cabling, and parallel data processing.

[0040] In some implementations, the geometry of the spherical housing determines the placement strategy for the lighting modules. For example, in a construction using a geodesic configuration, the lighting modules can be directly fixed to the structural panel using integrated mounting points aligned with geodesic coordinates. In a planar configuration, the lamps can be mounted along an internal rail system that follows the spherical profile. The camera module can maintain a predetermined position mounted on the internal rail system in both configurations, ensuring a consistent and repeatable imaging layout. This allows for the same calibration and alignment process across assemblies, even when the lighting components change between configurations.

[0041] The spherical housing can be formed from one or more modular frame segments, allowing the system to expand from a partial housing to a full housing depending on the application scenario. When constructed as partial segments of a sphere, the structure can take the form of a spherical crescent (a wedge-shaped segment of the sphere) suitable for target shooting setups or applications with limited field of view. The overall structure can be symmetrical about a central axis, ensuring a uniform distribution of camera and illumination modules and enabling consistent optical calibration regardless of the number of assembled frame segments.

[0042] In some embodiments, the scanning system may include a base frame supporting multiple modular structural panels that collectively define a spherical shape. These panels may form a complete or partial sphere, and in some embodiments may be geodesic structures to increase stiffness and reduce weight. In some examples, each panel may include an integrated mounting rail for securing imaging devices and illumination modules. The mounting system allows for precise adjustment and repositioning of the hardware using standardized quick-connect rail systems. In some examples, one or more light-emitting diodes (LEDs) or other light sources may be positioned in a predetermined array across the inner surface of the spherical housing.

[0043] In some implementations, modular rack sections can be joined using mechanical clamps and keyway systems without the need for tools for assembly or disassembly. In some examples, the entire rack can be transported in a compact form via freight carton.

[0044] Reference will now be made in detail to one or more embodiments of this disclosure, examples of which are shown in the accompanying drawings.

[0045] Figure 1 An example of a spherical scanning rack including multiple rack sections and multiple base platforms is shown. Figure 2 This is a top view showing the spherical scanning gantry. Figure 3 This is a side view showing the spherical scanning gantry. Figure 4 An example of a rack section comprising three curved mounting rails and the base of the rack section is shown, arranged on a base platform.

[0046] In some implementation schemes, refer to Figures 1 to 4 The spherical scanning system 100 (or "spherical scanning gantry") may include multiple gantry segments 300 configured circumferentially around a central axis AX and defining an imaging space 102 having a spherical shape, wherein the gantry segments 300 are configured to define at least one entrance 104 to provide access to the imaging space. For example, the spherical scanning system 100 may accommodate physical objects, including people, animals, and inanimate objects, in the imaging space 102. The multiple gantry segments 300 may be configured to be detached from each other for transport.

[0047] In some embodiments, each of the plurality of rack segments 300 may further include a base platform 400 supporting one or more arranged mounting rails 310. For example, each rack segment 300 may include a plurality of mounting rails 310 extending upward from the base platform 400 and connected to each other, wherein each of the plurality of mounting rails 310 is bent to define a portion of a spherical shape of the imaging space 102. In the example shown in this application, each rack segment 300 includes three mounting rails 310. In other examples, a rack segment 300 may include one or more (e.g., two) mounting rails 310 arranged on the base platform 400. In some examples, the mounting rails 310 may be made of at least one of aluminum, carbon composite material, or plastic. The plurality of rack segments 300 (e.g., mounting rails 310) may be configured along geodesic coordinates of a spherical shape.

[0048] The spherical scanning system 100 may also include a top bracket 106 that connects the upper ends of the mounting rails 310 to each other. For example, the top bracket 106 has a circular shape with a cutout in the middle. In some examples, the top bracket 106 may have other shapes, such as a star shape with radial arms, which connects the upper ends of the mounting rails 310 to each other. The upper ends of the mounting rails 310 may be circumferentially configured about a central axis AX and connected to the outer edge of the top bracket 106 via fastening members such as bolts and screws.

[0049] In some embodiments, each of the plurality of rack sections may further include a plurality of lighting modules 110 arranged at each of the plurality of mounting rails 310, and a plurality of camera modules 120 mounted to each of the plurality of mounting rails 310. For example, the plurality of lighting modules 110 may include various light sources (such as one or more LEDs) and lamp mounting brackets. For example, the plurality of camera modules 120 may include various camera platforms, such as digital SLR (DSLR) cameras, machine vision cameras, and professional cinema cameras. The plurality of camera modules 120 may also include camera mounting brackets.

[0050] refer to Figure 2 The base platform 400 is circumferentially configured around a center point O, with a central axis AX extending through the center point O. For example, each base platform 400 defines a segment angle CA between its sidewalls CL1 and CL2. The segment angle CA depends on the number of rack segments configured around the center point O. For example, the segment angle CA can be from 18 degrees to 90 degrees.

[0051] In some examples, the base platform 400 may have an angled outer circumference. For example, as... Figure 2As shown, the outer circumference of the base platform 400 has three flat surfaces with lengths SL1 and SL2 and a tangential angle TA between tangents TL1 and TL2. In some cases, SL1 may be greater than or equal to SL2. The tangential angle TA may be less than the segment angle CA. The base platform 400 may define the outer radius R1 of the spherical scanning system 100, and the top support 106 may define the inner radius R3 of the spherical scanning system 100. The outer circumference of the mounting track 310 may define a radius R2 between the outer radius R1 and the inner radius R3. For example, R1 may be in the range of 30" to 65", R2 may be in the range of 25" to 60", and R3 may be in the range of 8" to 40".

[0052] In some examples, the base platform 400 may have a circular, round outer circumference, without limiting TL1, TL2, SL1 and SL2.

[0053] In some examples, the vertical height H1 of the rack section 300 from the base platform 400 to the top support 106 can be in the range of 60" to 110", and the vertical height H2 of the base platform 400 can be in the range of 12" to 24". The width W of the base platform 400 can be twice the outer radius R1.

[0054] Figure 5 A curved mounting track 310 is shown arranged on the base 312 of the frame section.

[0055] refer to Figure 4 and Figure 5 Each rack section 300 may include at least one bridge 3101 disposed between the upper and lower ends of the rack section 300 and circumferentially connecting the rack section 300 to the mounting rail 310. Each mounting rail 310 may include a plurality of cutouts 3103, wherein various shapes are configured along the mounting rail 310. Each rack section 300 may also include a rack section base 312 (sub-base rack section) disposed between the base platform 400 and the mounting rail 310.

[0056] Each mounting rail 310 may include an upper frame section 3102 and a lower frame section 3104 connected to each other at a connecting portion 3106. For example, the connecting portion 3106 may include a top surface of the lower frame section 3104 and a bottom surface of the upper frame section 3102, which include precision-machined keyways. For example, a convex geometry may be provided on the bottom surface of the upper frame section 3102, and a corresponding negative (concave) recess 3108 may be provided on the top surface of the lower frame section 3104 (see...). Figure 6These keyways ensure precise alignment and structural rigidity. Once in place, the upper and lower frame sections can be mechanically fastened using vertical toggle clamps positioned to engage the keyway interfaces on both sides. This allows the frame sections to be securely locked together without tools, facilitating rapid assembly and disassembly in the field.

[0057] Figure 6 An example of a camera module and a lighting module mounted on a mounting track is shown. Figure 7A An example of a single mounting track including a lighting module and a camera module is shown. Figure 7B An exemplary configuration of a single mounting rail, cables, and circuit boards is shown. Figure 7C The rack section base supporting the camera trigger and network switch is shown. Figure 8 The lower frame of the base section of the rack section is shown.

[0058] refer to Figure 6 The mounting rail 310 accommodates illumination modules 110 and camera modules 120 arranged alternately along the curved shape of the mounting rail 310. The configuration of the illumination modules 110 and camera modules 120 can define specific scanning environments within the imaging space 102, such as brightness, directional variations in brightness, image capture sequence / timing, imaging angle, etc. For example, in some embodiments, the illumination modules 110 can be configured to provide constant or uniform illumination, wherein all illumination modules 110 illuminate at the same brightness at a time. In some embodiments, the illumination modules 110 can be configured to provide gradient illumination, wherein a first portion of the illumination modules 110 arranged on a first side of the rack is brighter than a second portion of the illumination modules 110 arranged on a second side of the rack. In some cases, the brightness of the second portion of the illumination modules 110 can drop to zero.

[0059] In some implementations, each modular rack segment 300 may form a curved portion of the spherical structure of the scanning system 100 and interconnect with adjacent rack segments 300 using precisely matched keyways and toggle clamps. The rack segments 300 can be used individually or in combination, ranging from single units for partial coverage to complete sets for full spherical housings, thus providing flexibility for a variety of scanning environments.

[0060] In some examples, rack sections 300 may use a spherical crescent-shaped profile to form the geometry, thereby ensuring that they maintain symmetry about the central axis AX when assembled. In some cases, the scanning system 100 may include structural rails or geodetic panels for mounting illumination and camera modules, as well as an internal compartment 345 for housing trigger controller 322, network switch 324, and power distribution hardware.

[0061] Each rack section 300 can be securely locked into place with adjacent rack sections and the base platform 400, enabling rapid assembly and disassembly while maintaining consistent alignment and device positioning. This design supports both stationary and mobile deployments, making the scanning system 100 suitable for scanning in the field or in controlled environments.

[0062] The scanning system 100 may include a structural rail comprising a mounting rail system 310 configured to hold the camera module 120 and the illumination module 110 in fixed, repeatable positions. This layout provides consistent calibration across deployment. In some examples, cables for power, data, and triggering are internally routed via dedicated channels to reduce clutter and prevent signal interference. Printed circuit boards (PCBs) 314 and 316 are located in the lower portion of the mounting rail 310 to distribute power to the camera and lights, simplifying assembly and maintenance.

[0063] For example, refer to Figure 7B Each rack segment 300 or mounting rail 310 may include multiple power cables 318 / 320 connected to multiple lighting modules 110 or multiple camera modules 120, multiple data cables connected to multiple camera modules 120, and multiple cable routing channels 319 configured to cover and guide the multiple power cables and multiple data cables.

[0064] In some implementations, to ensure the safe transport of the scanning system 100, specialized emulation plugs can be placed in each camera mounting location. These plugs can be precision-machined to the same dimensions as the actual camera mounts and include connector plugs for data, power, and trigger interfaces. This design prevents or reduces damage to fragile cabling and connectors during transport or rack reconfiguration. When inserted, the plugs can occupy the same mechanical coverage area as the camera module, providing strain relief and shielding for all sensitive wiring, thereby maintaining system integrity and reducing the risk of arrival failures or assembly delays.

[0065] In some embodiments, each mounting track 310 may include an inner surface facing the imaging space and an outer surface disposed radially outward of the inner surface, wherein the outer surface has (i) a vertical portion extending vertically relative to the base platform and (ii) a curved portion extending upward from the vertical portion and curving radially inward relative to the vertical portion. For example, the mounting track 310 may include an outer vertical portion 311, an outer curved portion 313 disposed above the outer vertical portion 311, an inner vertical portion 315, and an inner curved portion 317 disposed above the inner vertical portion 315 and facing the imaging space 102. In some examples, the height H4 of the inner vertical portion 315 may be less than the height H3 of the outer vertical portion 311, thereby increasing the capacity of the imaging space 102 and defining its spherical shape.

[0066] In some examples, reference Figure 7C and Figure 8 The rack section base 312 (sub-base rack section) may be located below the mounting rail 310 and house internal electronics, including a trigger distribution board 322 and a network switch 324 in an internal compartment 345. The rack section base 312 may be structurally integrated into each rack section (i.e., each rack section 300) to enable distributed control and communication across the scanning system 100 while minimizing external cabling. In some embodiments, the rack section base 312 may include a top plate 330 in contact with the mounting rail 310, a bottom plate 340 spaced apart from the top plate 330, and a post 350 disposed between the top plate 330 and the bottom plate 340, defining the internal compartment 345.

[0067] In some cases, internal electronics, such as trigger distribution board 322 and network switch 324, can be housed in sealed compartments to provide protection during transport and simplify deployment in modular scanning environments. In some examples, the system can support connection to external batteries or onboard racks, allowing off-grid operation without relying on building power.

[0068] In some examples, each rack segment 300 may include power distribution circuit boards 314 and 316 configured to supply power to the plurality of lighting modules 110 and the plurality of camera modules 120, respectively. Each rack segment 300 may also include a data storage device configured to store image data captured by the plurality of camera modules 120. A camera trigger controller 322 may be configured to control image capture by the plurality of camera modules 120, and a network interface circuit 324 may be configured to communicate with the power distribution circuit, the camera trigger controller, and the data storage unit.

[0069] In some examples, the scanning system 100 may include one or more connectors configured to connect rack segments 300 to each other. For example, the connectors may include brackets (e.g., Figure 1 Top support 106), elbow clamp 420 (see...) Figure 12A ) or keyway connectors (e.g., Figure 6 At least one of the recesses 3108).

[0070] Figure 9A and Figure 9B An example of a camera slot defined in a mounting track is shown. Figure 9B yes Figure 9A A magnified view of part A.

[0071] In some embodiments, each of the mounting tracks 310 may include a mounting bracket configured to engage with one of the plurality of camera modules 120, wherein the mounting bracket includes a guide groove configured to guide movement of that camera module 120 based on a camera module 120 mounted to the mounting bracket. For example, the mounting track 310 may define a plurality of guide rails configured to receive either a camera module 120 or an illumination module 110 and extend toward the imaging space. Reference Figure 9A and Figure 9B The mounting track 310 may include camera slots 360 that define the guide rail, each of which is configured to accommodate a camera module 120 based on linear insertion into the camera slot 360.

[0072] In some examples, each camera mount may include a custom-machined locking clamping mechanism designed for repeatable positioning. Mounting rail 310 may include a mechanical stop point that ensures the camera module returns to the exact same location each time it is removed and reinstalled, thus maintaining precise alignment in multi-camera scanning environments.

[0073] In some examples, modular mounting brackets can be provided to support multiple camera platforms, including digital SLR (DSLR) cameras, machine vision cameras, and professional cinema cameras. Modular mounting brackets allow for rapid camera interchangeability without recalibration. In some examples, locking mechanisms can engage with machined pawls and retaining screws via a sliding rail interface to prevent slippage during vibration or heavy use.

[0074] Figure 10A and Figure 10B An example of a camera and mounting bracket installed on a mounting track is shown. Figure 10B yes Figure 10A A magnified view of part B.

[0075] In some embodiments, mounting rail 310 may include a polarizer holder 122 coupled to at least one of the plurality of mounting rails 310, wherein the polarizer holder 122 is arranged on the lens side of one of the plurality of camera modules 120 facing the imaging space 102. Mounting rail 310 also includes a polarizer 126 mounted to the polarizer holder 122 and arranged with a predetermined polarization orientation relative to the lens axis LX of each of the plurality of camera modules 120. For example, the predetermined polarization orientation of polarizer 126 may be provided by a keyed connection between polarizer 126 and polarizer holder 122. For example, polarizer 126 may have a recess on one side, and polarizer holder 122 may have a mating protrusion configured to insert into the recess of polarizer 126. In some cases, polarizer holder 122 may include a polarizer cover 124 that secures polarizer 126 to polarizer holder 122 and covers the keyed connection between polarizer 126 and polarizer holder 122.

[0076] The polarizer holder 122 can be a precision-machined holder designed to house a circular or square polarizing filter within a 3D / 4D imaging rig. The polarizer holder 122 can be mounted directly onto the structural surface of the scanning system 100, independent of the camera body, allowing the polarization axis of the filter to remain globally aligned with the rig's spherical coordinate system. By decoupling the polarizer 126 from the camera 120 itself, this design eliminates the need for recalibrating or realigning the filter each time the camera is removed or remounted. The polarizer 126 can be held in a fixed, repeatable orientation relative to a sphere, ensuring consistent polarization behavior across all views and segments.

[0077] In some implementations, the camera 120 may be positioned behind the polarizer holder 122, allowing it to capture light that has already passed through the fixed polarizer 126. This ensures uniform polarization filtering across all shooting nodes, which can provide photometric consistency in shadow recovery, multi-flash, or reflection shooting workflows.

[0078] Figure 11 An example of a base platform that is connected to each other and defines a circular shape is shown. Figure 12A and Figure 12B The base platform is shown. Figure 13 An exemplary configuration of electronic components and fixtures in the base platform is shown.

[0079] In some embodiments, the base platform 400 may include an upper plate 414 supporting the frame section 300, a base frame 412 disposed below the upper plate 414, and an elbow clamp 420 disposed on the side surface of the base frame 412 and configured to connect to another frame section of the base platform 400 among a plurality of frame sections. In some examples, the upper plate 414 may define a plurality of cutouts 416 corresponding to the locations of a plurality of mounting rails 310. In some cases, the cutouts 416 may expose at least a portion of the base frame 412. The elbow clamp 420 may protrude from the side surface of the base frame 412.

[0080] In some cases, the toggle clamp 420 may be a horizontally oriented right-angle latching toggle clamp positioned on both the left and right sides of each base platform 400. The toggle clamp 420 can provide a secure attachment point for locking the lower frame section to the base structure. Like the upper frame section clamp, this mechanism can support tool-free locking, thereby ensuring that the scanning system 100 can be quickly assembled or arranged.

[0081] refer to Figure 11 As described above, the base platform 400 can be circumferentially configured around the central axis AX. The base platform 400 can provide foundation support for all segments and devices in the scanning system 100. The base platforms 400 can be interconnected via a circular guide rail system having precision-machined key sockets spaced along their perimeter. These sockets can serve as anchor points for vertical segment assemblies, thereby ensuring precise alignment and repeatable positioning during assembly.

[0082] See in some examples Figure 13 The base frame 412 can define space for housing electronic devices. For example, the base frame 412 can house a network switch 430, a computer and network attached storage (NAS) 440, a battery or power distribution circuit or device 450, and a central synchronization controller 460. The base frame 412 can provide a dedicated rack mounting base integrated into the base platform 400, thus providing robust compartments for network switches, edge computing servers, battery arrays, and power distribution units. This enclosure allows the scanning system 100 to operate independently of external infrastructure, eliminating dependence on building power and enabling rapid assembly in remote or mobile environments. It can also support onboard storage and triggering systems, making it an integrated, portable imaging solution.
