Description

Technical Field

[0001] The present invention belongs to the technical field of multimedia display processing, and in particular relates to an adaptive synchronization method, system and platform for a multi-projector wiring-free splicing and fusion system based on wireless communication. Background Art

[0002] The projector industry often faces challenges when splicing and fusing multiple units. Due to various unique circumstances, a single projector may experience variations in brightness, color, or image size. However, in traditional splicing and fusing scenarios, other projectors cannot synchronize and automatically achieve the same operation or change. This makes it difficult to maintain consistent brightness, color, and image size on the projected image, severely impacting the consistency and overall visual quality of the projected image.

[0003] Currently, existing technical solutions are difficult to achieve adaptive adjustment of the states of multiple projectors without wiring to meet the needs of practical applications.

[0004] In other words, traditional solutions typically use wired connections (such as HDMI and RS-232) to synchronize the status of multiple projectors. However, this solution requires complex cable connections between multiple projectors, increasing installation costs and maintenance difficulties. Wired communication is limited by distance, which may cause some projectors to update their status later. If a projector's status is abnormal (such as a sudden change in brightness), other devices will not be able to automatically synchronize and adjust, resulting in inconsistent images.

[0005] Therefore, in view of the technical problems and defects of the above existing technologies such as complex wiring, synchronization delay and poor fault tolerance, it is urgent to design and develop an adaptive synchronization method, system and platform for a multi-projector wiring-free splicing and fusion system based on wireless communication.

[0058] like Figure 1-Figure 2 2 is a flow chart of an adaptive synchronization method for a multi-projector wiring-free splicing and fusion system based on wireless communication provided by an embodiment of the present invention.

The terminal or other device can implement the adaptive synchronization function of a multi-projector non-wiring splicing and fusion system based on wireless communication through the provided interface. The present invention is further elaborated below in conjunction with the accompanying drawings.

[0062] like Figure 1 As shown, the present invention provides an adaptive synchronization method for a multi-projector wiring-free splicing and fusion system based on wireless communication, the method comprising the following steps:

[0063] S1. Generate and obtain first data corresponding to a projector; wherein the first data is state parameter data of the projector, including at least brightness data, color temperature data, and screen size data;

[0064] S2. Determine and generate second data corresponding to the first data, and generate corresponding third data based on the second data; wherein the second data is projector state parameter change data; and the third data is verification code data;

[0065] S3. Based on wireless communication and in combination with the third data, dynamically adjust the second data in real time and synchronously process the working status of all networked projectors.

[0066] The determining to generate second data corresponding to the first data, and generating corresponding third data based on the second data, further includes:

[0067] S21 . When a change in any state parameter of a projector is detected, generate corresponding third data including a timestamp, a device identifier, and a parameter type identification code.

[0068] When a change in any state parameter of a projector is detected, corresponding third data including a timestamp, a device identifier, and a parameter type identification code is generated, further comprising:

[0069] S211, the splicing state change timestamp, the last 6 digits of the initiating device MAC address and the parameter type identification code form a corresponding original string; wherein the parameter type identification code is encoded in hexadecimal, brightness corresponds to 0×01, color temperature corresponds to 0×11, and image size corresponds to 0×21;

[0070] S212: Perform a SHA256 hash operation on the original character string and generate a corresponding and unique verification code.

[0071] The method of dynamically adjusting the second data in real time based on wireless communication and combining the third data, and synchronously processing the working status of all networked projectors, further includes:

[0072] S31. Sending the state adjustment instruction carrying the third data to the nearest neighbor projector via the Bluetooth Mesh network first;

[0073] S32: After verifying the validity of the third data, the receiving projector synchronously adjusts its own state parameters and relays the data to the unsynchronized adjacent projector.

[0074] S33, loop execution until all networked projectors complete status synchronization processing.

[0075] The method of dynamically adjusting the second data in real time based on wireless communication and combining the third data, and synchronously processing the working status of all networked projectors, further includes:

[0076] S34, reading the zoom lens stepper motor stroke parameters and determining the corresponding projection size;

[0077] S35 , comparing the received screen size parameters with the local parameters; triggering automatic calibration when the difference exceeds a preset threshold.

[0078] The method of dynamically adjusting the second data in real time based on wireless communication and combining the third data, and synchronously processing the working status of all networked projectors, further includes:

[0079] S36. Maintain a list of processed verification codes; when a new verification code is received, query the list to see if there is a duplicate record; if so, discard the data packet.

[0080] Specifically, in an embodiment of the present invention, an adaptive state synchronization method for a multi-projector wiring-free splicing and fusion system is provided, comprising the following steps: real-time monitoring of local state parameters through a built-in Bluetooth device in each projector, wherein the state parameters include at least brightness, color temperature, and screen size; when a change in the state parameters of any projector is detected, a verification code ① is generated containing a timestamp, a device identifier, and a parameter type identification code; a state adjustment instruction carrying the verification code ① is preferentially sent to the nearest neighboring projector through the Bluetooth Mesh network; the receiving projector verifies the validity of the verification code ① and then synchronously adjusts its own state parameters, and relays it to the unsynchronized adjacent projector; the loop is executed until all networked projectors complete state synchronization.

[0081] Among them, the method for generating the verification code ① is: concatenating the state change timestamp, the last 6 digits of the initiating device MAC address and the parameter type identification code to form an original string; performing a SHA256 hash operation on the original string to generate a unique verification code.

[0082] The parameter type identification code is encoded in hexadecimal, where brightness corresponds to 0x01, color temperature corresponds to 0x11, and picture size corresponds to 0x21.

[0083] The state synchronization process includes: reading the zoom lens stepper motor stroke parameters to determine the projection size; comparing the received picture size parameters with the local parameters; and triggering automatic calibration when the difference value exceeds a preset threshold.

[0084] The Bluetooth device performs duplicate detection before forwarding data: maintains a list of processed verification codes; when a new verification code is received, queries the list to see if there is a duplicate record; if so, discards the data packet.

[0085] The core solution of the present invention includes: Bluetooth Mesh networking: each projector establishes a self-organizing network through a built-in Bluetooth module to achieve wireless communication. Status monitoring and verification code generation: real-time monitoring of local status parameters (brightness, color temperature, screen size). When the status changes, a unique verification code ① is generated (based on timestamp, MAC address, and parameter type hash operation). Relay-type synchronous propagation: When the status changes, the projector preferentially sends synchronization instructions to the nearest neighboring node. After the receiving node verifies the verification code ①, it updates its own status and continues to forward it to the unsynchronized node. Anti-duplication mechanism: Verification code ① is used to avoid repeated execution of instructions to ensure transmission efficiency.

[0086] In other words, the purpose of the present invention is to provide a technical solution for adaptive and synchronous adjustment of the states of multiple projectors, so as to solve the problem in the prior art that multiple projectors cannot automatically synchronize state changes in splicing and fusion scenarios, resulting in inconsistent projection images, and to achieve adaptive state adjustment of all machines without wiring in a larger range.

[0087] The solution system consists of multiple projectors and a built-in Bluetooth device in each projector (e.g., a Bluetooth device with data reading and communication capabilities). The Bluetooth device can read the status information of the projector in real time, including but not limited to brightness, color, and screen size.

[0088] Status Monitoring and Information Transmission: When any projector experiences changes in brightness, color, or screen size, its built-in Bluetooth device immediately reads the device's status information and generates a status message containing a verification code. This status message is then preferentially transmitted to the Bluetooth device of the nearest projector that is capable of communicating with it.

[0089] Verification code generation rules: "Verification code ① is generated by hashing the following elements: state change timestamp (accurate to milliseconds); the last 6 digits of the initiating device's MAC address; and the parameter change type identifier (brightness = 0x01, color temperature = 0x11, size = 0x21). Example: When a device with a MAC address of AA:BB:CC:DD:EE:FF adjusts its brightness at 2023-08-2014:30:25.500,

[0090] Verification code = SHA256("20230820143025500_DDEEFF_01_11_21_")

[0091] State Adjustment and Data Forwarding: The Bluetooth device of the projector that receives the signal will immediately analyze the state adjustment parameters contained in the signal and use these parameters to synchronously adjust the state of the projector. At the same time, the Bluetooth device of the projector will transmit the state information (including verification code ①) to the nearest projector with which data has not yet been exchanged. Before each data exchange, verification code ① will be used for verification to prevent repeated data transmission to a device that has already adjusted its state. (Reply to comments: Low power mode and dynamic tuning are not considered. Only the latest data collection and matching are performed.)

[0092] Loop operation: Repeat the above data forwarding and state adjustment operations until all projectors receive the status information and complete the state adjustment, thus achieving state adjustment and adaptation for all devices on a large scale. (Reply to the comment: The color adjustment of the projector is based on the comparison and replacement of the three parameters contained in the hash value. Different parameters correspond to different overall effects. There is no special algorithm. The current projection size is determined by reading the parameters of the zoom lens stepper motor travel and the depth perception lens. I will not elaborate on this here.)

[0093] The solution of the present invention can improve the consistency of the picture. That is, by real-time synchronization of state changes, it can ensure that the projection images of multiple projectors remain consistent in terms of brightness, color and picture size. (Reply to the comment: This only applies to projectors produced by EFUN. The synchronization problem of large-scale clusters is not considered for the time being.) The overall visual effect of the projected image is greatly improved. Advantage of no wiring: Using Bluetooth devices for wireless communication, there is no need for complex wiring operations, which reduces the cost and difficulty of installation, and also improves the flexibility and scalability of the system. Preventing data duplication: The verification mechanism of verification code ① effectively avoids the repeated transmission of data, improving the efficiency of data transmission and the stability of the system.

[0094] The equipment installation and configuration of this solution is to install a Bluetooth device with data reading and communication functions in each projector, and configure the corresponding parameters to ensure that the Bluetooth device can work normally and communicate with other devices.

[0095] Status monitoring and information generation: The Bluetooth device monitors the status of the projector in real time. When it detects changes in brightness, color, screen size, etc., it immediately reads the relevant status information and generates status information including verification code ①. Verification code ① can be a unique identifier generated based on information such as a timestamp and device number.

[0096] Data transmission and reception: The Bluetooth device of the projector experiencing a status change will preferentially send this status information to the Bluetooth devices of the nearest other projectors that can communicate with each other. After receiving the status information, the other projectors' Bluetooth devices will verify the verification code ①. If the verification is successful, the subsequent operation will continue.

[0097] State Adjustment and Data Forwarding: A projector that receives and passes verification of the state information uses the state adjustment parameters contained in the signal to synchronously adjust its own state. It then transmits the state information to the nearest projector with which it has not yet exchanged data, and re-verifies the verification code ① before transmitting it.

[0098] Loop and complete: Repeat the above data forwarding and status adjustment operations until all projectors receive status information and complete status adjustment, thereby achieving status adjustment adaptation of all machines.

[0099] To achieve the above objectives, the present invention also provides a multi-projector wiring-free splicing and fusion system adaptive synchronization system based on wireless communication, such as Figure 3 As shown, the system is used to implement the adaptive synchronization method of the multi-projector wiring-free splicing and fusion system based on wireless communication, and the system includes:

[0108] The third processing module is configured to execute in a loop until all networked projectors complete the state synchronization process.

[0109] The first generating module further includes:
