Description

Technical Field

[0001] The present invention relates to the field of virtual reality technology, and in particular to a method and system for integrating virtuality and reality into a full-scale virtual reality. Background Art

[0002] With the continuous advancement of virtual reality (VR) technology, how to achieve seamless integration of the real world and the virtual world has become a key research direction. Traditional VR systems are often limited by issues such as spatial positioning accuracy, content presentation effects, and user interaction experience, making it difficult to provide a truly immersive experience.

[0003] Currently, virtual reality (VR) technology faces the following technical bottlenecks in the application of virtual-reality integration that need to be addressed: Physical limitations of wearing a device Traditional VR technology relies on wearable devices such as helmets and glasses to achieve an immersive experience, but it has significant physiological limitations: Lack of comfort: Head-mounted devices generally weigh ≥300g, causing cervical compression after prolonged use, with a 40% incidence of dizziness. Users typically use the device for ≤30 minutes. Interaction gap: Wearable devices isolate the real environment and cannot achieve real-time interaction between virtual elements and physical space. This poses a safety hazard in scenarios that require virtual-real collaboration, such as industrial maintenance and medical surgery.

[0004] Spatial perception accuracy and field of view limitations Insufficient positioning accuracy: Existing naked-eye VR devices rely on optical markers for positioning, with an accuracy of ≤5mm. This cannot meet the millimeter-level requirements of scenarios such as cultural relic restoration (requiring 1200dpi accuracy) and precision parts assembly. Lack of field of view coverage: Traditional cylindrical / spherical display devices have a vertical field of view ≤180°, a bottom blind spot, and an information loss rate ≥25%, making it impossible to achieve 720° panoramic immersion.

[0005] Content adaptation efficiency and cost bottlenecks Offline transformation is inefficient: Billions of existing 360° panoramic VR content rely on manual adjustment, with a conversion efficiency of ≤0.5TB / minute. Furthermore, custom development is required to accommodate special-shaped screens, increasing transformation costs by over 60%. Severe image quality loss: When traditional super-resolution algorithms upscale 4K content to 8K, the image information loss is ≥30%, which cannot meet the needs of large-space cinema-level displays.

[0006] Weak adaptability to extreme environments Invalid in strong light scene: ≥10 4 Under lux lighting, existing equipment has an image distortion rate greater than 2% and a color difference ΔE greater than 3.0, making it unsuitable for scenes such as outdoor exhibitions and direct sunlight. Poor environmental robustness: Under temperature fluctuations from -10°C to 40°C, the error drift of traditional laser positioning equipment is ≥1.5mm. When the humidity is greater than 60%, the optical components are prone to fogging, causing system failure. Summary of the Invention

[0024] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] See also Figure 1-4 The present invention provides a method for integrating virtual and real life into a true virtual reality, comprising the following steps: Use light field reconstruction technology to obtain spatial data of the real environment; Applying algorithmic dimensionality processing to convert the acquired spatial data into a data format that can be used for virtual reality display; Implement spatial programming to adjust the position and form of virtual elements in physical space according to user needs to achieve a true virtual-reality fusion experience.

[0026] This technical solution achieves a seamless fusion of the real and virtual worlds through three core technological breakthroughs: light field reconstruction, algorithmic dimensionality enhancement, and spatial programming. This approach is applicable to a variety of fields, including large-scale offline media displays, digital museums, and smart cultural tourism.

[0027] Principle of light field reconstruction technology Digital acquisition and reconstruction of physical space light fields are achieved through a three-order optical stack architecture: Static layer: 6500K spectral matrix (CIE1931 color gamut coverage 99.7%) creates a benchmark lighting environment, matching the human eye's visual characteristics through spectral energy distribution. After 120 minutes of continuous use, the visual fatigue index decreases by 47%; Dynamic layer: P0.9-P2.5 adaptive LED array (17800PPI density) analyzes dynamic light field changes through modulation transfer function (MTF≥0.8), eliminating 99.3% motion blur at a 120Hz refresh rate; Interactive layer: 200 dots / cm 2 The laser grid and the 1000Hz TOF array construct a three-dimensional Cartesian coordinate system. By coordinating the time-of-flight (TOF) method with triangulation, they achieve 0.1mm positioning accuracy on the X / Y / Z axes and a tactile feedback delay of ≤8ms.

[0028] Algorithm dimensionality upgrading processing principle SE(3) manifold optimization: The pose error function is defined based on the Lie group SE(3): E(R,t)=∑∥p i −(Rp i +t)∥ 2 , by iteratively optimizing the rotation matrix R and translation vector t through gradient descent, the 6DoF pose solution error is controlled within ±0.03°; GAN super-resolution network: The generator network extracts features through block (3, 64, stride = 1), block (64, 128), block (128, 256), block (256, 512), and finally generates 18K images through Conv2d (512, 3); The discriminator outputs a probability map of N×1×H / 8×W / 8, using the LeakyReLU (α=0.2) activation function; Overall architecture overview The generator network uses a "progressive feature extraction" design, connecting four block modules and one convolutional layer in series to achieve super-resolution processing from low resolution (4K) to high resolution (18K). Its core logic is to gradually extract more abstract visual features by doubling the number of channels layer by layer (3 → 64 → 128 → 256 → 512), ultimately restoring the high-resolution image. Internal structure of block Each block contains three core components. Take block (3, 64, stride = 1) as an example: Convolutional layer: Number of input channels: 3 (corresponding to RGB images), number of output channels: 64; Convolution kernel size: usually 4×4 (default setting based on patent scenarios), stride: 1, padding: 1 (to keep the feature map size unchanged); Function: Extract local features of the image through convolution operation, and generate 64 feature maps through 64 output channels.

[0029] LeakyReLU activation function: Formula: f(x)={x αx,x≥0 x<0} where α=0.2 (default slope); Function: Solve the ReLU "dead neuron" problem, retain negative features, and improve the network's nonlinear expression ability.

[0030] Asymmetric Batch Normalization (AsymmetricBatchNorm): Asymmetric design: Batch normalization (BatchNorm) is added only to non-input layers (i.e., block (64, 128) and subsequent modules), and not to the input layer block (3, 64); effect: Stabilize the training process: avoid gradient vanishing by normalizing the feature map distribution; Preserve original features: BN is not used in the input layer to prevent the destruction of the original distribution of RGB pixels and ensure the accuracy of underlying feature extraction.

[0031] Meaning of the block parameter Take block(in_ch, out_ch, stride) as an example: in_ch: the number of input channels, for example, 3 in the first block corresponds to 3 channels of the RGB image; out_ch: the number of output channels, which determines the number of feature maps. For example, 64 means 64 feature maps are generated. stride: convolution step size, when stride=1, the feature map size remains unchanged, when stride=2, the size is halved (except for the first block, subsequent blocks may implicitly perform upsampling operations) Detailed explanation of network process Input layer: Receive 4K resolution RGB image (3 channels) and enter block (3, 64, stride=1); Output 64-channel feature map, the size is the same as the input (maintained by padding=1).

[0032] Middle block layer: block(64,128), block(128,256), block(256,512): Each time the number of channels is doubled, the feature map size is restored to the input size through upsampling (such as transposed convolution) or interpolation, achieving "feature abstraction + resolution improvement"; BatchNorm is added to all non-input layers to stabilize deep network training.

[0033] Output layer: Conv2d(512,3): 512-channel input, 3-channel output (restored to RGB image); The convolution kernel size is usually 1×1, which is used to integrate high-level features and generate 18K resolution images.

[0034] Technical advantages and scenario adaptation Innovation of asymmetric BN: The input layer does not use BN to avoid destroying the original pixel distribution. It is suitable for scenes with high requirements for color fidelity in VR content (such as restoration of cultural relics). BN is used in subsequent layers to solve the gradient instability problem when generating large-size images (18K) and ensure super-resolution accuracy (the amount of image information is increased by 5.2 times).

[0035] Channel number increasing strategy: The design of doubling the number of channels from 3 to 512 conforms to the logic of "shallow extraction of low-level features such as edges and colors, and deep extraction of high-level features such as semantics and structures", and is adapted to the detailed restoration of complex scenes in VR content (such as 1200dpi patterns).

[0036] Combination with scenes: Combined with the SE(3) manifold optimization algorithm, the high-resolution image output by the generator can accurately match the spatial positioning (0.1mm accuracy), achieving visual consistency in virtual and real fusion; In 10 5 In lux strong light scenes, the features extracted by the generator can be combined with the light field compensation matrix to achieve chromatic aberration control of ΔE<1.2.

[0037] Material perception engine: Based on the cross entropy loss function L=− ∑N i=1∑87 c=1y i,c logy^ i,c , where, where, y i,c is the true label (0 or 1), y^ i,c is the model prediction probability, N is the total number of samples 87 types of surface property models are trained, and the reflectivity prediction error is ≤0.8% through multi-source data fusion of images / point clouds / sensors.

[0038] Principles of Spatial Programming Nonlinear distortion compensation: SIGGRAPH2024 algorithm fits spatial transformation relationships through Bezier surfaces f(x,y)=(x′,y′), reducing the original distortion rate from 2.1% to 0.05%, and supporting 0.1° accuracy correction for 23 types of special-shaped screens, such as domes and folding surfaces; Three-level computing power scheduling: Dynamically allocate edge-cloud computing power through the "perception-measurement-routing" system, achieve a modeling speed of 5.7㎡ / second based on the load balancing algorithm, and parallel processing ≥10 6 Operations / second; Light field compensation matrix: LabPQR spatial spectrum mapping based on 1269 Munsell color patches, in 10 4 -10 5 Under lux illumination, a graded mapping strategy (strong light compression / weak light enhancement) is used to ensure that the color difference ΔE is less than 1.2.

[0039] Working principle of the optimal technical solution Third-order optical architecture enhanced design Dynamic layer refresh rate synchronization: The LED array and TOF sampling frequency are synchronized through a phase-locked loop (PLL). At a motion speed of 1.2m / s, the light field sampling phase error is ≤1°, avoiding motion smear. Interaction layer topology optimization: The laser grid uses octree encoding to optimize the 30m 3 The space is dynamically divided into voxels. When the user enters the interactive area, the local sampling density is increased to 400 points / cm 2 , positioning update delay ≤ 5ms.

[0040] GAN super-resolution network improvement Generator residual connection: Add skip connections F(x)=x+H(x) between blocks to retain the low-frequency texture of the 4K input (such as the basic surface texture of cultural relics) and integrate it with the high-frequency details (such as decorative carvings) generated by 18K, achieving 1200dpi decorative restoration; Discriminator multi-scale input: It simultaneously receives the original 4K image and the 32×32 pixel blocks of the generated 18K image, improves the authenticity of micro-texture through multi-scale discrimination, and reduces the Fréchet Inception Distance (FID) by 37%.

[0041] Extreme environment adaptation mechanism Glare compensation grading strategy: 10 4 -5×10 4 lux: Enable the LabPQR color gamut compression algorithm, adjust the RGB three-channel energy ratio to 1.2:1:0.8, and maintain ΔE < 1.0; 5×10 4 -10 5 Lux: Combined with polarizers and a light field compensation matrix, it dynamically adjusts the LED color temperature to 5500K, suppressing specular glare. Temperature and humidity compensation: In an environment of -10°C to 40°C, the laser grid transmission power is adjusted through the PID algorithm (compensation coefficient 0.02dB / °C) to ensure that the TOF ranging error is ≤ 0.15mm.

[0042] Key steps: Laser grid calibration uses Zhang’s calibration method to solve the camera intrinsic parameters through 20 sets of checkerboard patterns; The TOF array is trained with 100 sets of standard distance samples (0.5-10m) to train the TOF calibration model.

[0043] Implementation points: Point cloud acquisition uses SLAM algorithms to build a global map, with a 230 square meter scene matching accuracy of 99.8%; The light field compensation matrix is ​​based on the spectral data of 1269 Munsell color patches and generates real-time compensation coefficients through LabPQR spatial interpolation.

[0044] Dynamic optimization mechanism: The SE(3) pose and light field compensation parameters are updated in real time through user interaction data (such as gaze direction and touch position), forming a "perception-computation-rendering-feedback" closed loop to achieve adaptive optimization of virtual-reality fusion scenes.
