[0004] Current illustration display devices generally rely on lighting to enhance the display effect of illustration works. The display effect is relatively simple and is greatly affected by the venue. The lighting effect is also prone to light pollution, thus affecting the performance of the illustration. Summary of the invention

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides a display device for digital illustration design to solve the problems existing in the above-mentioned background technology.

[0006] The present invention provides the following technical solution: a display device for digital illustration design, comprising a device chassis, a control console is fixedly connected to the top of the device chassis, an experience device is arranged on the side of the control console, two connecting rods are fixedly connected to the upper part of the device chassis, a display device is fixedly connected to the top of the connecting rods, and a display device is fixedly connected to the side of the device chassis. Illustration works can be played on the display device to attract audiences, and static playback of illustrations can be converted into dynamic playback by using technologies such as Canvas or SVG of HTML5, providing users with a more vivid and rich visual experience.

[0007] Furthermore, the display device adopts an ultra-high-definition LED screen, which uses precise splicing technology to achieve seamless connection of multiple screens to form an entire huge display wall. The chassis of the device has a built-in professional color management system to ensure that the color of the illustration works can remain accurate and consistent under different lighting conditions.

[0008] Furthermore, the chassis of the device is provided with a pressure sensor, an infrared sensor, a light adjustment device and a music player. When the audience approaches or touches it, a specific interactive effect can be triggered. The light and background music in the exhibition hall are automatically adjusted according to the style and theme of the illustration. A surround sound or stereo system is used to adjust the sound effects according to the atmosphere and plot changes of the illustration, creating an atmosphere that matches the work.

[0009] Furthermore, a projector is provided on the side of the console, and the projector can project the illustration content displayed on the console onto the display device via a wireless network. The console is provided with a touch screen, and the illustration works displayed on the display device can be selected, enlarged, reduced or rotated by touching the screen. The display angle and method can be changed according to the audience's needs, thereby improving the display effect.

[0010] Furthermore, the console is also provided with an integrated data analysis device and a voice guide device. The integrated data analysis device can collect the audience's interactive data and behavioral preferences, and intelligently recommend related or similar illustrations based on the audience's interests and feedback. The voice guide device can provide voice introductions when displaying illustrations, which can greatly stimulate the audience's sense of identification, thereby improving the illustration display effect.

[0011] Furthermore, the experience device is equipped with a head-mounted display, and the AR enhanced effect of the illustration work can be seen in the real space by wearing the head-mounted display. The head-mounted display is internally provided with a motion capture system, a content management system and an interactive design system.

[0012] Furthermore, the motion capture system includes a gyroscope, an accelerometer, a magnetometer and a camera, which can capture the user's position, posture, line of sight direction and other information in real time, as well as image and video data of the surrounding environment, and can handle motion capture tasks in complex scenes to ensure stable performance in a variety of environments. The captured motion data can be further analyzed, and the AR scene information can be transformed according to the motion data, which can improve the realism and interactivity of the game characters.

[0013] Furthermore, the content management system can be used to upload, edit and manage illustration content, supports the import of illustration files in various formats, provides rich editing tools, and makes data uploading more convenient. At the same time, the system can record the audience's interactive data to provide a basis for subsequent content optimization and personalized recommendations.

[0014] Furthermore, the interactive design system is internally provided with a processing unit, which has built-in three-dimensional space processing algorithms and data processing algorithms. The three-dimensional space processing algorithm updates the data of the user's spatial position changes in the real environment in real time, thereby changing the internal picture of the head-mounted display accordingly, ensuring the synchronous update and integration of virtual information and real scenes. The data processing algorithm is used to process data obtained by the motion capture device.

[0015] SIFT is used to extract feature points, edges or feature areas from the collected real-world images. The scale space is constructed using Gaussian pyramid. A series of images of different scales are generated by performing Gaussian blurring and downsampling on the image at different scales. Local extreme points are detected in the Gaussian difference pyramid as candidate key points. At each candidate position, the precise position and scale of the key point are determined by fitting a refined model. At the same time, low-contrast points and edge response points are removed. The gradient direction distribution characteristics of the pixels in the neighborhood of the key point are used to specify direction parameters for each key point. The gradient direction histogram is generated by counting the gradient direction and amplitude of the pixels in the neighborhood of the key point. The neighborhood is divided into multiple sub-regions with the key point as the center. In each sub-region, the gradient accumulation values ​​in 8 directions are calculated to form seed points. Each key point consists of multiple seed points, and each seed point contains gradient information in 8 directions. The gradient information of all seed points is combined into a high-dimensional vector (usually 128 dimensions) as the descriptor of the key point. The key point descriptors in the template image and the real-time image are compared using metrics such as Euclidean distance, so as to extract stable local feature points with scale, rotation and illumination invariance in real-world images.

[0016] BFMatcher is used to match the feature points in the real world with the feature points in the virtual object (illustration work), and the correspondence between these feature points is found. According to the matched feature point pairs, the SVD algorithm is used to calculate the transformation matrix from the real world coordinate system to the virtual object coordinate system. Each pair of points is located in two images and corresponds to the same physical point in the real world. Assuming there are N pairs of matching points, there is a set of matching point pairs (pi, qi), where pi is a point in the real world image (expressed in homogeneous coordinates, i.e. [x, y, 1]T), and qi is the corresponding point in the virtual object image (also expressed in homogeneous coordinates). Two 3*N matrices P and Q are constructed, where The columns of P are the transpose of pi, and the columns of Q are the transpose of qi; then the mean centers of P and Q are calculated, and the corresponding means are subtracted from each point to obtain the centralized matrices P′ and Q′; then the centralized matrix H=P′Q′T is subjected to singular value decomposition, that is, H=UDVT, where U and V are orthogonal matrices, D is a diagonal matrix whose elements on the diagonal are singular values; then the rotation matrix is ​​constructed using quaternions, and the translation vector t can be obtained by calculating the difference between the centers of the two point sets, that is, t=μq-Rμp, where μp and μq are the means of P and Q respectively, and R is the rotation matrix obtained from the SVD result, and finally the transformation matrix is ​​obtained through the rotation matrix and the translation vector.

[0017] Use the calculated transformation matrix to position the virtual object in the real-world scene, fuse the virtual object with the real-world image, ensure that the lighting, shadow, perspective and other effects are consistent with the real environment, and render the fused image to the display device for users to view and interact with. At the same time, feature extraction, matching and transformation matrix calculation are re-performed regularly or on demand to correct errors caused by device movement, environmental changes, etc.

The head-mounted display is equipped with a motion capture system, a content management system and an interactive design system.

[0034] The motion capture system includes a gyroscope, accelerometer, magnetometer and camera, which can capture the user's position, posture, line of sight direction and other information in real time, as well as image and video data of the surrounding environment.

The data processing algorithm is used to process the data obtained by the motion capture device.

[0037] Data processing algorithm: Extract feature points, edges or feature areas from the collected real-world images through SIFT. The scale space is constructed using Gaussian pyramid. A series of images of different scales are generated by performing Gaussian blurring and downsampling on the image at different scales. Local extreme points are detected in the Gaussian difference pyramid as candidate key points. At each candidate position, the precise position and scale of the key point are determined by fitting a refined model. At the same time, low-contrast points and edge response points are removed. The gradient direction distribution characteristics of the pixels in the neighborhood of the key point are used to specify direction parameters for each key point. The gradient direction histogram is generated by counting the gradient direction and amplitude of the pixels in the neighborhood of the key point. The neighborhood is divided into multiple sub-regions with the key point as the center. In each sub-region, the gradient accumulation values ​​in 8 directions are calculated to form seed points. Each key point consists of multiple seed points, and each seed point contains gradient information in 8 directions. The gradient information of all seed points is combined into a high-dimensional vector (usually 128 dimensions) as the descriptor of the key point. The key point descriptors in the template image and the real-time image are compared using metrics such as Euclidean distance, so as to extract stable local feature points with scale, rotation and illumination invariance in real-world images.

[0038] Three-dimensional space processing algorithm: Use BFMatcher to match the feature points in the real world with the feature points in the virtual object (illustration work), find the correspondence between these feature points, and use the SVD algorithm to calculate the transformation matrix from the real world coordinate system to the virtual object coordinate system based on the matched feature point pairs. Each pair of points is located in two images and corresponds to the same physical point in the real world. Assume that there are N pairs of matching points, among which there is a set of matching point pairs (pi, qi), where pi is a point in the real world image (expressed in homogeneous coordinates, i.e. [x, y, 1]T), and qi is the corresponding point in the virtual object image (also expressed in homogeneous coordinates). Construct two 3*N matrices P and Q, where the columns of P are the transpose of pi and the columns of Q are the transpose of qi; then the mean centers of P and Q are calculated, and the corresponding means are subtracted from each point to obtain the centralized matrices P′ and Q′; then the centralized matrix H=P′Q′T is subjected to singular value decomposition, i.e. H=UDVT, where U and V are orthogonal matrices, D is a diagonal matrix whose elements on the diagonal are singular values; then the rotation matrix is ​​constructed using quaternions, and the translation vector t can be obtained by calculating the difference between the centers of the two point sets, i.e. t=μq-Rμp, where μp and μq are the means of P and Q respectively, and R is the rotation matrix obtained from the SVD result, and finally the transformation matrix is ​​obtained through the rotation matrix and the translation vector.

[0039] Use the calculated transformation matrix to position the virtual object in the real-world scene, fuse the virtual object with the real-world image, ensure that the lighting, shadow, perspective and other effects are consistent with the real environment, and render the fused image to the display device for users to view and interact with.
