[0047] To make the objectives and advantages of the present invention clearer, the present invention will be further described below with reference to embodiments; it should be understood that the specific embodiments described herein are merely for explaining the present invention and are not intended to limit the present invention.

[0048] Preferred embodiments of the present invention will now be described with reference to the accompanying drawings.

[0050] This invention provides a mechanical physical pixel screen image display system and method based on servo cluster control, laying the foundation for future intelligent movable skin. In the field of movable building skin, it moves the parametric units of the building skin, achieving light tracking and sun shading in conjunction with energy conservation and environmental protection, presenting different forms of the building skin, realizing dynamic building skin aesthetics, and disseminating media information.

[0051] Please refer to Figure 1, which is a schematic diagram of the structure of a mechanical physical pixel screen image display system 100 based on servo cluster control according to an embodiment of the present invention. The mechanical physical pixel screen includes several physical pixel units arranged in an array; each physical pixel unit can be independently servo-controlled to present changes in physical pixel size, brightness, or color. The system 100 includes:

[0052] Image data acquisition module 101 is used to acquire source data of video or images;

[0053] The video data stream acquired by the image data acquisition module 101 can come from, but is not limited to, video files, camera signals, video signal inputs (such as DP, HDMI, DVI, VGA, AV, USB, etc.), sensor inputs, algorithm calculation results, AI data inputs, or image inputs used to achieve various intelligent functions. Video files are acquired as digital files; camera or video signal inputs are acquired via hardware. Alternatively, the image data acquisition module 101 can also acquire only the source data of an image, such as a single input image displayed statically on a mechanical physical pixel screen.

[0054] The image pixel acquisition module 102 acquires the pixel values ​​of the corresponding coordinate positions of the video frame or the image according to the mechanical physical pixel screen resolution to obtain pixel data;

[0055] In this embodiment, the main purpose of the image pixel acquisition module 102 is to convert high-resolution frame data of video or image data streams into low-resolution display data for a mechanical physical pixel screen. A common practice in the prior art is to convert the video resolution from K*L to a scaled-down video of M*N. However, this method has the drawback of causing blurry mechanical physical pixel displays. This is because video downscaling typically uses a fusion algorithm, which divides the high-resolution K*L video into M*N partitions and then replaces the pixels with the average value of all pixels in each partition. This results in some clearly defined video frames becoming blurry after compression.

[0056] In embodiments of the present invention, the above operations are achieved using a video pixel acquisition method, specifically including:

[0057] Acquire frames of the video or the image, wherein the resolution of the frame of the video or the image is K*L;

[0058] In the frame or the image, pixel values ​​are collected at coordinate positions corresponding to the mechanical physical screen resolution M*N; where K, L, M, and N are all positive integers.

[0059] The frame or image with a resolution of K*L is partitioned into M*N corresponding partitions;

[0060] The pixel value of at least one pixel is collected with the center position of each partition as the center, and the average value of the pixel value of the at least one pixel is calculated as the pixel value of that partition;

[0061] Pixel data is obtained based on the pixel values ​​of M*N partitions, that is, the pixel values ​​of the corresponding coordinate positions of the video frames or the image.

[0062] In the embodiments of the invention, since the average value of one or more pixels is collected at the center of each partition, the outline of the reduced video image collected in this way will be clearer and the colors will be more vivid, which is beneficial to the clear expression of the content image of the mechanical physical pixel screen. In the method of video pixel acquisition, it is not advisable to collect too many pixels at the center of the partition, otherwise the image outline will be blurry, just like the fusion algorithm.

[0063] The pixel motion mapping unit 103 is used to map pixel data into servo motion data of each physical pixel unit according to the pre-established correspondence between pixel values ​​and servo motion.

[0064] The cluster signal transmission module 104 is used to distribute the servo motion data of each physical pixel unit to the control module of the corresponding physical pixel unit through the cluster network.

[0065] The control module 105 includes a servo drive unit 1051. The servo drive unit 1051 executes control commands to achieve synchronous servo control of each physical pixel unit to move precisely by a certain value, thereby enabling the mechanical physical pixel screen to display a picture pattern corresponding to the frame or image of the source data. Each control module 105 independently controls several servo drive units 1051, and each servo drive unit 1051 controls the movement of one physical pixel unit.

[0066] Optionally, in some embodiments, the servo motion mode of the physical pixel unit includes, but is not limited to, rotation angle servo motion, volume scaling servo motion, position movement servo motion, and comprehensive servo motion combining multiple servo motion modes; the direction of the servo motion includes, but is not limited to, vertical, horizontal, longitudinal, random, multi-level, and random multi-level directions.

[0067] Specifically, in one embodiment of the present invention, the servo motion mode can be selected as rotation angle servo motion, and the angle rotation mode of the physical pixel unit can also be horizontal rotation, vertical rotation, multi-axis rotation, or rotation in other directions. The servo drive unit 1051 executes control instructions to realize synchronous servo control of each physical pixel unit to precisely rotate a certain angle. The instruction representation of angle data can be implemented according to specific requirements. There are many ways to represent angle data. 0 to 360 degrees can also be represented as 0 to 63, 0 to 255, 0 to 511, 0 to 1023, 0 to 10000, etc. The appropriate angle data representation method can be selected according to different angle subdivision resolutions. The angle data representation method can also be selected according to coding habits. For example, the common range of grayscale channel values ​​from black to white for a video pixel is 0 to 255 (1 byte). When the angle subdivision resolution requirement is not high, the grayscale value data of the video pixel can be directly used as the driving data for the motor subdivision angle. This avoids massive cluster data calculation, greatly saves chip computing resources, and has a faster real-time speed.

[0068] According to the above embodiments of the present invention, the mechanical physical pixel screen of the present invention has variable physical decorative properties, and can still retain physical three-dimensional images after power failure; it maintains high-intensity contrast images and clear images under outdoor sunlight; it also has green and environmentally friendly low power consumption performance; it will not cause light pollution at night; it can realize the dynamic or static display of video frames or image images on the mechanical physical pixel screen, with fast real-time speed.

[0069] Furthermore, in some embodiments, the mechanical physical screen is composed of several mechanical module arrays arranged in a certain manner, and each mechanical module array is composed of several physical pixel units arranged in an M*N array. Each mechanical module array is independently controlled by a corresponding control module 105, and each servo drive unit 1051 controls the rotation of one physical pixel unit. In this embodiment, the mechanical physical screen is designed as a modular array arrangement, which greatly facilitates the installation, movement, and transportation of the mechanical physical screen, reduces labor costs, and lowers maintenance costs.

[0070] Optionally, in some embodiments, as shown in FIG2, which is a structural schematic diagram of a mechanical physical pixel screen image display system based on servo cluster control according to another embodiment of the present invention, the control module 105 further includes: a data optimization and calculation unit 1052.

[0071] The data optimization and calculation unit 1052 is used to preprocess the servo motion data, calculate the vectorized waveform data suitable for mechanical pixel servo control, generate simplified control instructions and transmit them to the servo drive unit.

[0072] Data preprocessing includes, but is not limited to, filtering operations, vectorized waveform operations, and motion trajectory operations. Data preprocessing may include at least one or more of the above algorithms.

[0073] Each pixel in a video stream represents a grayscale value that is a waveform that continuously changes between black and white (typically 0-255) at a fixed frequency. For example, if the video frame rate is 30 frames per second, then the fixed frequency of this waveform is 30 Hz. Directly using this fixed-frequency waveform data to drive mechanical physical pixels is like pressing the accelerator pedal of a car 30 times per second to move forward or backward, with each press required to reach the target position. This would undoubtedly generate enormous mechanical losses, energy consumption, and noise, significantly reducing the lifespan of the machinery.

[0074] Therefore, in the embodiments of the present invention, the effective method one is filtering: filtering out data that is far below the mechanical action response. Since the mechanical action response cannot meet these data requirements, the existence of these redundant data will only interfere with the normal operation of the mechanical physical pixels. The effective method two is pixel data stream vectorized waveform diagram calculation: First, we need to find key points in the waveform diagram at a fixed frequency, such as peaks, troughs, and points of change that exceed the filtering value. Then, we analyze the time, speed, and waveform patterns used between these key points, and use formulas to draw the waveform diagram motion curve, thereby calculating the vectorized waveform data suitable for the servo motion control of the mechanical pixel motor.

[0075] In this embodiment, the data structure is greatly optimized by combining the filtering operation with the vectorized waveform operation. The redundant data is compressed in large quantities using the algorithm that conforms to servo control, thereby achieving control optimization. It should be noted that although the data optimization operation unit can play a very important role in some preferred embodiments of the present invention, it is not necessary for the implementation of the mechanical physical pixel screen image display system controlled by servo cluster.

[0076] Furthermore, in some embodiments, the pixel motion mapping unit 103 is used to map the pixel data into servo motion data for each physical pixel unit according to a pre-established correspondence between pixel values ​​and servo motion, specifically including:

[0077] Determine whether the pixel value of the frame image corresponds to the mechanical physical screen resolution M*N as an RGB value or a grayscale value;

[0078] When the pixel value is an RGB value, the multi-channel RGB value of the acquired pixel is converted into a single-channel grayscale value with black and white levels.

[0079] Based on the characteristics of different sizes, brightness, and colors presented by the unit in different directions, each physical pixel unit is divided into at least one servo motion zone, and the correspondence between the grayscale value and the data of each servo motion zone is established in advance.

[0080] Based on the pre-established correspondence between the grayscale value and each servo motion interval data, the pixel values ​​of the video frame or the image corresponding to the mechanical physical screen resolution M*N are mapped to the servo motion data of each physical pixel unit.

[0081] The pre-established correspondence between grayscale values ​​and each servo motion zone is defined based on the size and grayscale values ​​of the physical pixel unit as it moves to different positions. Furthermore, a physical pixel unit can be divided into several servo motion zones. Specifically, taking an angle zone as an example, each angle zone is further divided into several sub-angles to correspond to the size and grayscale level changes of the mechanical physical pixel.

[0082] Furthermore, in some embodiments, the mechanical pixel unit includes: a power drive mechanism, a bracket, and a load shape; wherein the bracket is fixedly mounted on a mounting base; the power drive mechanism has its body fixedly connected to the bracket and its output end fixedly connected to the load shape; or the power drive mechanism has its output end fixedly mounted to the bracket and its body fixedly connected to the load shape. In this embodiment, the power drive mechanism drives the load shape to perform servo motion, thereby causing the load shape to exhibit changes in physical pixel size, brightness level, or color.

[0083] Optionally, in some embodiments, the mechanical pixel unit includes: a power drive mechanism and a bracket; wherein the bracket is fixedly mounted on a mounting base; the body of the power drive mechanism is fixedly connected to the bracket, and its output end is shaped to represent changes in physical pixel size, brightness level, or color; or, the output end of the power drive mechanism is fixedly connected to the bracket, and its body shape is used to represent changes in physical pixel size, brightness level, or color. According to this embodiment, especially for sufficiently simple load shapes, this embodiment can use the output end shape or body shape of the power drive mechanism to replace the load shape, that is, the power drive mechanism itself serves as the load shape, thereby simplifying the structure of the mechanical pixel unit.

[0084] In this embodiment of the invention, the mounting base is not limited to a specific shape or structure, and can be a plane, a curved surface, a keel structure, or other shapes or structures.

[0085] In this embodiment of the invention, the power drive mechanism includes, but is not limited to, electric, pneumatic, hydraulic, magnetic, physical kinetic energy, biological kinetic energy, chemical kinetic energy, optical kinetic energy, etc.

[0086] In embodiments of the present invention, the load shape is not limited to a specific shape, and can be sheet-like, box-like, tubular, or other shapes.

[0087] Furthermore, in some embodiments, a light source with independently controllable brightness and color can be added inside or outside the load design, controlled by the control module 105, to control the load design to transmit and emit light from the inside out, or to provide external reflective illumination; and the light source's brightness and color changes are driven by the control module 105 based on the video pixel RGB data acquired by the image pixel acquisition module 102. This embodiment's load design with independently controllable brightness and color light source enables the mechanical physical screen to display richer images.
