Description

Technical Field

[0001] This invention relates to the field of light and shadow interpretation technology, and more specifically, to an immersive spatial crystal light sculpture interpretation system. Background Technology

[0002] Immersive light and shadow performance technology, as an emerging form of digital art expression, has developed rapidly in recent years in the fields of exhibitions, stage performances, and public space decoration. Its core objective is to construct a perceptible and participatory visual narrative environment in three-dimensional space through multimodal interaction and dynamic optical effects. Current mainstream solutions are mainly based on projection mapping and LED matrix technology, combined with sound, light, and electricity media to achieve basic spatial light and shadow effects. However, limitations such as the static nature of optical media, system response lag, and insufficient multi-device collaboration make it difficult to achieve a highly free and interactive three-dimensional light sculpture experience. Current technological shortcomings: Interaction limitations caused by optical medium curing Traditional light sculpture systems often use reflective media with fixed shapes (such as building facades and static sculptures), whose physical properties cannot be changed in real time. For example, polycarbonate prism panels can only produce preset diffraction patterns. When the audience moves or the ambient light changes, the system lacks the ability to dynamically adjust the deformation of the medium / optical parameters, resulting in a disconnect between the light and shadow effects and the interactive behavior, and an interruption of the immersive experience.

[0003] 2. Lack of dynamic distortion compensation mechanism Existing projection mapping technology has significant shortcomings in real-time correction of moving objects. When a rotating device carries an optical medium, conventional geometric correction algorithms can only handle single-axis rotational distortion. For nonlinear deformations caused by multi-degree-of-freedom composite motion (such as synchronous deflection and vibration around the XYZ axes), no effective dynamic compensation model has been established, resulting in torn projection images, color inaccuracies, and serious damage to visual integrity.

[0004] Low efficiency of multi-subsystem collaboration Modules such as environmental perception, content generation, and optical projection often operate independently. For example, a commercial light sculpture system uses a separate architecture: the Kinect sensor detection latency is >200ms, the media server generates content and distributes it to the projection cluster via HDMI, and the communication time in each link results in the final light effect lagging behind the sound source by >500ms. Such a fragmented system cannot support the millisecond-level response required for real-time interaction, greatly weakening the continuity of the immersive experience.

[0005] Therefore, an immersive spatial crystal light sculpture interpretation system is proposed to address the above problems. Summary of the Invention

[0006] In order to overcome the above-mentioned defects of the prior art, embodiments of the present invention provide an immersive spatial crystal light sculpture performance system to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, the present invention provides the following technical solution: an immersive spatial crystal light sculpture performance system, comprising: an icosahedral base frame made of lightweight carbon fiber, with an embedded electromagnetic shielding layer and heat dissipation duct; a distributed high-lumen laser projection array installed at each vertex of the frame, including at least 6 independently focusable wide-angle laser projection modules, a color mixing light source module covering the full visible spectrum of 380-780nm, and an integrated dynamic aperture modulator; an optical-grade artificial crystal polyhedral cluster suspended in the center of the frame, the surface of which is provided with a microprism diffraction layer with a prism density of 50-200 lines / mm and the prism orientations of each face being mutually different; a pose adjustment mechanism consisting of a three-axis servo motor group and a six-dimensional vibration sensor connecting the crystal cluster; and a central controller, which executes a spatial light field fusion algorithm through a gigabit fiber optic network and synchronously controls the projection timing error to ≤1ms.

[0008] Preferably, the color mixing light source module of the distributed laser projection array adopts a four-channel mixing scheme of red, green and blue primary color laser diodes and amber phosphors, and achieves stepless brightness adjustment of 0.01-30000 lumens through a dynamic aperture modulator. Moreover, the optical axes of each projection unit converge at the geometric center of the crystal cluster with an incident angle of 15°±2°.

[0009] Preferably, the surface of the crystal cluster is composited with a programmable electrochromic film and a piezoelectric tactile feedback layer, wherein the electrochromic film covers no less than 30% of the crystal surface area and supports independent adjustment of the transmittance of the four RGBY channels, and the piezoelectric feedback has a response frequency range of 20-400Hz and can generate mechanical vibration waves with an amplitude of 0.1-5mm.

[0010] Preferably, the central controller has a built-in spatial pose collaborative computing engine that calculates the dynamic distortion compensation relationship between the rotational attitude of the crystal cluster and the projected image in real time. The algorithm includes: Euler angle pose matrix construction based on six-dimensional vibration sensor data, cosine correction model of the angle between the projection plane and the crystal plane, and gamma curve optimization module for multi-channel color brightness equalization.

[0011] Preferably, it integrates an environmental perception module, including a 1280×720 resolution infrared depth sensor array arranged on the base frame, an ambient light intensity monitor with an illumination range of 0.1-100000 lux, and a sound wave positioning matrix composed of 4 microphones. The three work together to generate a heat map of the audience spatial distribution and sound source orientation vector data.

[0012] Preferably, the environment perception module is dynamically coupled with the content generation engine, wherein the content generation engine includes: a Fourier acousto-optic converter that maps the audio spectrum into an RGB spectral sequence in real time, a spatial interaction logic unit that triggers regional lighting effects based on the audience displacement vector, and an AI rendering core that uses a generative adversarial network to synthesize dynamic light and shadow materials.

[0013] Preferably, the pose adjustment mechanism drives the crystal cluster to perform a composite motion trajectory, including continuous rotation around the XYZ axes ±180° with an angular acceleration of 0.5-5 rad / s². 2 The simple harmonic vibration mode and the resonant frequency adaptive adjustment in response to changes in sound pressure level, with the positioning accuracy of the three-axis servo motor set reaching 0.05°.

[0014] Preferably, the microprism diffraction layer interacts with the projected light field to form dynamic interference patterns. Its optical effects include: total internal reflection extension of the incident laser at the prism interface, coherent diffraction superposition between polycrystalline planes, and dynamic topological transformation of moiré fringes generated during rotation, ultimately generating a stereoscopic light sculpture that can be observed with the naked eye in a spherical space with a radius of 3-8 meters.

[0015] An immersive light and shadow performance method for an immersive spatial crystal light sculpture performance system includes: capturing the audience's spatial coordinates and sound source location in real time using an infrared depth sensor and a sound wave positioning matrix; generating a suitable light and shadow media stream by an AI rendering core based on ambient light intensity data and sound source spectrum; driving a three-axis servo motor group to make the crystal cluster move along a preset resonance trajectory; synchronously controlling a distributed projection array to project a registered image processed by a spatial light field fusion algorithm onto the moving crystal cluster; and generating a three-dimensional light pattern that dynamically changes with the audience's displacement in space using the light interference effect of a microprism diffraction layer.

[0016] The technical effects and advantages of this invention are as follows: Compared with existing technologies, the technical effects and advantages of this invention are as follows: A breakthrough upgrade of the immersive light sculpture performance system is achieved through the synergistic effect of a dynamically adjustable optical crystal medium and a distributed projection array. Specifically, a crystal cluster with a surface-integrated microprism diffraction layer and an electrochromic functional layer is used as the core optical carrier. Driven by a servo mechanism, it undergoes multi-degree-of-freedom pose transformations. Combined with the pose-projection mapping model calculated in real time by the central controller, the problem of projection distortion in the moving medium is effectively overcome. Simultaneously, based on the fusion of multi-source data from the environmental perception module, an AI generation engine dynamically synthesizes light and shadow content adapted to the current spatial state, enabling a closed-loop interaction between the projected light field, the crystal's physical state, and the audience's behavior. This constructs an intelligent light field system that can instantly respond to ambient light intensity, sound source location, and audience displacement, generating a three-dimensional light sculpture in three-dimensional space that combines visual depth and physical interactivity, significantly improving the real-time performance and immersive experience of the light and shadow performance.

[0018] Figure 2 This is a flowchart of the process of the present invention. Detailed Implementation

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] Example 1: As attached Figure 1-2As shown, (1) an immersive spatial crystal light sculpture performance system includes: an icosahedral base frame made of lightweight carbon fiber, which has an embedded electromagnetic shielding layer and heat dissipation duct; a distributed high-lumen laser projection array installed at each vertex of the frame, including at least 6 sets of independently adjustable wide-angle laser projection modules, a color mixing light source module covering the full visible spectrum of 380-780nm, and an integrated dynamic aperture modulator; and an optical-grade artificial crystal polyhedral cluster suspended in the center of the frame, the surface of which has a ridge density of 50-200 lines / mm and each face The system comprises a microprism diffraction layer with mutually different prism orientations; a pose adjustment mechanism consisting of a three-axis servo motor group connecting the crystal cluster and a six-dimensional vibration sensor; and a central controller that executes a spatial light field fusion algorithm and synchronously controls the projection timing error to ≤1ms via a gigabit fiber optic network. The base frame uses lightweight T800 grade carbon fiber tubing, connected by 3D-printed titanium alloy nodes to form an icosahedral structure with sides of 1.2 meters. The inner wall of the frame is composited with a 0.5mm thick copper mesh electromagnetic shielding layer, and serpentine cross-sections of 6×8mm are cut along the inside of the tubing. The frame features a heat dissipation duct with forced convection airflow reaching 3 m / s; the distributed projection array comprises 12 groups of 50,000-lumen laser projection units, evenly distributed across 20 vertices of the frame. Each unit integrates a wide-angle lens with an adjustable focal length of 28-100mm, a four-channel light mixing system consisting of a 445nm blue laser, a 520nm green LD, a 638nm red laser, and a 590nm amber phosphor wheel, as well as a liquid crystal aperture modulator with a response time of 10μs; the centrally suspended crystal cluster is a 40cm diameter rhombic octahedron artificial crystal. The crystal is constructed using a nanoimprinting process to create microprism layers with varying density gradients on each crystal facet (80 lines / mm in the central region and 150 lines / mm in the edge region). The prism directions are arranged according to a 22.5° interval between adjacent crystal faces. The pose adjustment mechanism uses three servo motors with a rated torque of 12 N·m to drive universal joints, thereby rotating the crystal cluster along the XYZ axes. A six-dimensional vibration sensor (including a three-axis accelerometer with a range of ±16g and a three-axis gyroscope with a range of ±2000 dps) provides pose data feedback at a frequency of 1 kHz. The central controller uses a platform such as the Xilinx Zynq UltraScale+ MPSoC, which synchronously controls the projection unit via an SFP+ fiber optic interface using the 1588v2 protocol, with timing errors controlled within 0.8 ms.

[0021] (2) The color mixing light source module of the distributed laser projection array adopts a four-channel mixing scheme of red, green and blue primary color laser diodes and amber phosphor. The stepless brightness adjustment of 0.01-30000 lumens is achieved through a dynamic aperture modulator. The optical axes of each projection unit converge at the geometric center of the crystal cluster with an incident angle of 15°±2°. The light power ratio of the four-channel light engine in the color mixing light source module is 45% blue light / 30% green light / 20% red light / 5% amber light. After beam combining by dichroic mirrors, the lumen adjustment is achieved through a liquid crystal aperture with a variable aperture of 0.5-15mm. The adjustment curve conforms to the CIE 1976 L*a*b* uniform color space. The optical path of the projection unit is precisely calibrated so that all projection optical axes converge at 50cm from the center of the frame, the incident angle is controlled within the range of 13°-17°, and an illumination spot with an overlap rate of ≥85% is formed on the crystal surface. When performing dark scenes, the aperture shrinks to its minimum size, reducing the base brightness to 0.01 lumens, which, combined with laser pulse width modulation, enables 10-bit grayscale control.

[0022] (3) The surface of the crystal cluster is composited with a programmable electrochromic film and a piezoelectric haptic feedback layer. The electrochromic film covers no less than 30% of the crystal surface area and supports independent adjustment of the transmittance of the four RGBY channels. The piezoelectric feedback has a response frequency range of 20-400Hz and can generate mechanical vibration waves with an amplitude of 0.1-5mm. The surface of the crystal cluster is coated with a tungsten oxide-based electrochromic film by magnetron sputtering, covering 35% of the crystal surface area and divided into 256 independent control units. Each unit supports completing the transmission within 0.1 seconds. The light intensity can be switched from 15% to 85%, and the attenuation coefficients for the four RGBY colors are adjustable (red light 0.2-0.8 / green light 0.3-0.7 / blue light 0.4-0.9 / yellow light 0.25-0.75). The piezoelectric feedback uses a PZT-5H piezoelectric ceramic sheet, which is embedded in the non-optical surface inside the crystal cluster. When receiving low-frequency signals of 20-150Hz, it generates mechanical wave simulation vibration effect with an amplitude of 0.1-2mm. When receiving high-frequency signals of 150-400Hz, it generates ultrasonic tactile feedback with an amplitude of ≤0.5mm.

[0023] (4) The central controller has a built-in spatial pose collaborative computing engine that calculates the dynamic distortion compensation relationship between the crystal cluster rotation posture and the projected image in real time. The algorithm includes: constructing an Euler angle pose matrix based on six-dimensional vibration sensor data, a cosine correction model of the angle between the projection plane and the crystal plane, and a gamma curve optimization module for multi-channel color brightness equalization. The collaborative computing engine performs three-layer processing in real time: first, it converts the six-dimensional sensor data into an Euler angle matrix in ZYX order with an accuracy of 0.01°; second, it establishes a projection correction model. When the crystal rotates around the X-axis by an angle θ, the corresponding projection plane image is compressed by a factor of cosθ along the Y-axis and the trapezoidal distortion is compensated; finally, it dynamically adjusts the Gamma value of each channel (range 1.8-2.6) through the gamma optimization module so that the chromaticity difference ΔE under different incident angles is less than 3. The algorithm takes ≤3ms to process each frame and supports 120fps real-time pose compensation.

[0024] (5) It integrates an environmental perception module, which includes a 1280×720 resolution infrared depth sensor array arranged on the base frame, an ambient light intensity monitor with an illumination range of 0.1-100000 lux, and a sound wave positioning matrix composed of 4 microphones. The three work together to generate a heat map of the audience spatial distribution and sound source orientation vector data. The environmental perception module consists of a tetrahedral array of 4 sets of ToF infrared depth sensors (1280×720 resolution, detection distance 0.2-5m) to generate a point cloud density of 500pt / m. 3 The system includes a spatial heat map; an ambient light sensor using a chip such as the BH1750FVI, achieving a signal-to-noise ratio >60dB in a 0.1 lux dark field; and a sound wave localization matrix consisting of four MEMS microphones arranged in a tetrahedral configuration, with the sound source azimuth angle calculated using the TDOA algorithm (accuracy ±2°). The three data sources are then fused using Kalman filtering to output the audience's coordinates and movement speed vector.

[0025] (6) The environment perception module is dynamically coupled with the content generation engine, which includes: a Fourier acousto-optic converter that maps the audio spectrum to an RGB spectral sequence in real time; a spatial interaction logic unit that triggers regional lighting effects based on the viewer's displacement vector; and an AI rendering core that synthesizes dynamic light and shadow materials using a generative adversarial network. The acousto-optic converter transforms the audio signal into a spectrum using a 4096-point FFT and generates an RGB spectral sequence according to the Hertz-hue mapping rule (0-200Hz → red / 200-2kHz → green / 2k-20kHz → blue). The spatial interaction logic unit is set to trigger the crystal cluster to deflect 15°±3° towards the viewer when the viewer enters the core area with a radius of 2 meters. The AI ​​rendering core adopts the StyleGAN3 network architecture and generates dynamic textures by training with 100,000 sets of light and shadow materials, with a response latency of <50ms. When the system detects a sound pressure level above 90dB, it automatically switches to a high-contrast lighting effect mode.

[0026] (7) The pose adjustment mechanism drives the crystal cluster to perform a composite motion trajectory, including continuous rotation around the XYZ axis ±180° and angular acceleration of 0.5-5 rad / s. 2 The system features simple harmonic vibration mode and adaptive resonant frequency adjustment in response to changes in sound pressure level. The three-axis servo motor assembly achieves a positioning accuracy of 0.05°. The posture mechanism has three preset motion modes: slow continuous rotation in display mode (X-axis 5° / s, Y-axis 3° / s, Z-axis 8° / s); simple harmonic vibration in interactive mode (angular frequency 2Hz, amplitude ±30°); and resonance mode activated when the sound pressure level exceeds 85dB, dynamically adjusting the motor torque via a PID controller to lock the vibration frequency within ±5% of the sound source's fundamental frequency. The servo motor uses a 17-bit absolute encoder with a repeatability of 0.05°.

[0027] (8) The microprism diffraction layer interacts with the projected light field to form dynamic interference patterns. Its optical effects include: total internal reflection of the incident laser at the edge interface, coherent diffraction superposition between polycrystalline planes, and dynamic topological transformation of moiré fringes generated during rotation. Finally, a stereoscopic light sculpture that can be observed with the naked eye is generated in a spherical space with a radius of 3-8 meters. The optical effect of the microprism layer is divided into three stages: the incident laser undergoes total internal reflection at the edge interface, expanding the original beam into a conical beam of ±12°; the expanded beam interferes between adjacent crystal planes, forming diffraction fringes with a spatial period of 0.5-3 mm; when the crystal rotates, multiple sets of diffraction fringes superimpose to generate dynamic moiré topology. For example, when two sets of 100 lines / mm edges move at an angle of 10°, a rotating light fringe with a period of 10 mm is generated. This effect forms a stereoscopic light sculpture with a height of 2.5 meters and a viewing angle of 150° at a distance of 3 meters from the crystal.

[0028] (9) An immersive light and shadow performance method for an immersive spatial crystal light sculpture performance system, comprising: capturing the audience's spatial coordinates and sound source orientation in real time through an infrared depth sensor and a sound wave positioning matrix; generating a suitable light and shadow media stream by an AI rendering core based on ambient light intensity data and sound source spectrum; driving a three-axis servo motor group to make the crystal cluster move along a preset resonance trajectory; synchronously controlling a distributed projection array to project a registered image processed by a spatial light field fusion algorithm onto the moving crystal cluster; and generating a three-dimensional light pattern that dynamically changes with the audience's displacement in space using the light interference effect of a microprism diffraction layer. The method flow is specifically defined as follows: the infrared sensor updates the audience's coordinates every 33ms, the sound wave matrix tracks the sound source orientation in real time, the AI ​​rendering core automatically selects a material library based on ambient light intensity (enabling high saturation color schemes when the light intensity is >500 lux), and maps the sound source fundamental frequency to a light pulsation frequency; the servo motor drives the crystal to move along a preset resonance trajectory. The equation motion is used to project image sequences that have been gamma-corrected and cosine-compensated by the projection array. The microprism layer projects interference patterns onto the audience area. When the audience's movement speed is greater than 1 m / s, the pattern density increases adaptively by more than 20%.

[0029] Example 2: Multi-source data joint modeling scenario Step 1: System Initialization and Spatial Calibration First, the heat dissipation system embedded in the base frame is activated (airflow speed 3m / s), and the distributed projection array undergoes preheating and calibration: 12 sets of laser projection units sequentially emit reference crosshair spots. The positional deviation of the spots on the preset calibration plate is detected by the vision sensor of the central controller, driving the adjustable focus lens to adjust the intersection point of the optical axes to the geometric center of the crystal cluster (error ≤0.1mm). Simultaneously, the pose adjustment mechanism performs a zeroing action, and the three-axis servo motor drives the crystal cluster to rotate to the initial pose (X / Y / Z axes = 0°). The six-dimensional vibration sensor collects zero-point drift data and compensates for it. This process takes approximately 30 seconds until all projection units form a uniform illumination field with an overlap rate ≥85% on the crystal surface.

[0030] Step 2: Environmental Perception and Data Fusion The environmental sensing module has started collecting data in real time: An infrared depth sensor array emits 940nm wavelength infrared light and receives reflected signals to generate spatial point clouds (density 500pt / m²). 3 Mark the audience coordinates (e.g., audience A is located at X=1.2m, Y=0.8m, Z=0m). The ambient light intensity monitor samples the illuminance every 100ms (e.g., the current ambient light intensity is 80 lux). If it exceeds 500 lux, it triggers the high brightness mode. The sound wave localization matrix calculates the sound source location using the TDOA (Time Difference of Arrival) algorithm: Assuming the time difference between the sound received by microphones 1 and 2 is Δt = 0.58 ms and the speed of sound is v = 340 m / s, then the azimuth angle θ = arcsin(v × Δt / microphone spacing) indicates that the sound source is located at 30° on the horizontal plane.

[0031] The central controller fuses the above data through Kalman filtering and outputs a heat map of audience distribution and a sound source vector (e.g., sound source intensity 85dB@30°).

[0032] Step 3: AI Content Generation and Mapping The content generation engine dynamically synthesizes lighting and shadow content based on environmental data: The acousto-optic converter performs a 4096-point FFT (Fast Fourier Transform) on the input audio, decomposing the spectrum into frequency components. The mapping rules are as follows: red (R=255, G=0, B=0) is output when the frequency f < 200Hz, green (R=0, G=255, B=0) is output when 200Hz ≤ f < 2000Hz, and blue (R=0, G=0, B=255) is output when f ≥ 2000Hz. The mixed sound sources generate an RGB spectrum sequence. The AI ​​rendering core calls the pre-trained StyleGAN3 model (the dataset contains 100,000 sets of light ripple materials), and generates high-density dynamic moiré stripe materials when the audience's movement speed is detected to be >1m / s. Once the spatial interaction logic determines that the audience has entered the core area (radius < 2m), it generates a crystal deflection command (target posture: X=0°, Y=15°, Z=0°).

[0033] Step 4: Crystal Pose Coordination Control The position adjustment mechanism drives the crystal cluster to perform compound motion: The basic motion mode adopts the parametric equations: X-axis angle = 5 × sin(2π × 0.5t) + 30° (t is time in seconds), Y-axis angle = 10 × cos(π × 0.5t), realizing simple harmonic motion with a period of 4 seconds; When the sound pressure level is >85dB, the resonance mode is activated: the PID controller calculates the motor torque τ=Kp×e(t)+Ki×∫e(t)dt+Kd×de(t) / dt, where e(t)=sound source fundamental frequency-current vibration frequency, and the vibration frequency is locked within ±5Hz of the sound source fundamental frequency by adjusting τ. The six-dimensional sensor provides real-time feedback of pose data, and the Euler angle conversion module outputs the current pose (e.g., X=32.1°, Y=8.7°, Z=0.2°).

[0034] Step 5: Real-time correction of the projected light field The central controller performs spatial light field fusion: Distortion compensation: The amount of distortion in the projected image is calculated based on the crystal's orientation. If the crystal rotates around the X-axis by θ = 32.1°, then the Y-axis image scaling factor = cos(32.1°) = 0.846, and a trapezoidal correction algorithm is applied simultaneously. Color balance: Adjust the Gamma value of each projection unit to address the difference in incident angle (e.g., Gamma=2.2 for the top projection unit and Gamma=1.9 for the bottom unit) to ensure that the color difference ΔE < 3. Timing synchronization: Using the 1588v2 precision clock protocol, all projection units are controlled to synchronously project processed image frames (120fps) within 0.8ms.

[0035] Step 6: Generation of optical interference effect The interaction between the projected light field and the crystal microprism layer produces three-dimensional light patterns: Beam expansion: The laser undergoes total internal reflection at a 50 lines / mm ridge interface, and the original beam diameter is expanded by 3 times (e.g., incident beam Φ10mm → outgoing beam cone Φ30mm). Coherent diffraction: The interference of extended beams from adjacent crystal planes forms fringes with a spatial period of λ = d × sinα (d = edge spacing 0.02 mm, α = beam angle 15° → period ≈ 0.77 mm). Dynamic Moiré effect: When two sets of 100 lines / mm edges move at a relative angle of 10°, the generated Moiré fringe period T=1 / (2×100×sin(5°))≈5.7mm, and the fringes exhibit a spiral topological transformation during the rotation.

[0036] Step 7: Interactive Response and Adaptive Optimization The system responds to environmental changes in real time: Tactile feedback: When the audience touches the crystal, the piezoelectric feedback device receives a 200Hz signal and generates a mechanical wave with an amplitude of 1mm to transmit vibration; Brightness adjustment: When the ambient light intensity rises to 1000 lux, the dynamic aperture modulator increases the projection brightness to 25000 lumens; Path update: Audience movement vector change > 0.5 m / s 2 At that time, the AI ​​engine regenerated the material with a 25% increase in light pattern density.

[0037] All data is recorded in the operation log, and system parameters are automatically calibrated every 24 hours.

9. An immersive light and shadow interpretation method for an immersive spatial crystal light sculpture interpretation system, characterized in that... include: The infrared depth sensor and acoustic positioning matrix are used to capture the spatial coordinates of the audience and the location of the sound source in real time. The AI ​​rendering core generates a suitable light and shadow media stream based on ambient light intensity data and sound source spectrum; drives a three-axis servo motor group to make the crystal cluster move along a preset resonance trajectory; synchronously controls the distributed projection array to project the registered image processed by the spatial light field fusion algorithm onto the moving crystal cluster; and uses the light interference effect of the microprism diffraction layer to generate a three-dimensional light pattern that dynamically changes with the displacement of the audience in space.
