Technical Field

[0001] This invention relates to the technical field of LED screens, and in particular to a method, apparatus, computer equipment, and storage medium for the mobile installation of LED screens. Background Technology

[0002] Currently, with the development of LED technology, LED screens have been widely used in various industries, and users are beginning to use LED screens in more and more scenarios.

[0003] To facilitate use in different environments, existing LED displays are usually equipped with mobile supports, requiring manual assistance for movement. However, in large outdoor settings, due to the heavy weight of large LED displays, they cannot be moved by simple supports. Instead, large equipment such as lifting vehicles are often used in combination with manual adjustments for movement and installation. This method is costly, expensive, and requires a long installation and debugging time.

[0004] The existing technical solutions mentioned above have the following drawbacks: the efficiency of moving and installing LED screens is low. Summary of the Invention

[0005] To improve the efficiency of mobile installation of LED screens, this application provides a method, apparatus, computer equipment, and storage medium for mobile installation of LED screens.

[0006] The above-mentioned objective of this application is achieved through the following technical solution: A method for moving and installing an LED screen, the method comprising: Preprocess the LED sub-screens and number them in a matrix according to their order; Obtain installation destination information and automatically navigate according to the installation destination information to transport the LED sub-screen to the location corresponding to the installation destination information; Obtain the sub-screen positioning information corresponding to all the LED sub-screens, and analyze the sub-screen positioning information to generate a sub-screen positioning signal; When the sub-screen is in place signal is triggered, a photographic image of the moving base is acquired, the photographic image of the moving base is identified, and the LED sub-screens are arranged according to the corresponding matrix number in combination with the sub-screen positioning information; The LED sub-screens are assembled according to the matrix numbering, and the flatness of the splicing of the LED sub-screens is detected and fine-tuned.

[0007] By adopting the above technical solution, pre-designed connectors are installed on the LED sub-screen. These connectors are arranged in a certain order, and the LED sub-screen is matrix-numbered according to the arrangement of these connectors to facilitate subsequent splicing and installation of the LED sub-screen, thus improving the efficiency of LED sub-screen mobile installation. The system acquires the user-preset installation destination information, and the automated mobile base equipped with the LED sub-screen uses automatic navigation technology to automatically navigate and move the LED sub-screen to the target location, saving manual operation time and effort and improving the efficiency of LED sub-screen mobile installation. The positioning system integrated into the LED sub-screen acquires the LED sub-screen's positioning information, compares the current positioning information with the installation destination information, and determines whether the LED sub-screen is in place. If the positioning conditions are met, a corresponding sub-screen positioning signal is generated, automatically determining the LED sub-screen's position. The system ensures that all LED sub-screens reach their designated installation positions and confines them within a preset range, facilitating subsequent installation and improving the efficiency of LED screen relocation. When a sub-screen is triggered into position, the system acquires images from cameras integrated on the automated mobile base, performs image recognition and processing, and combines real-time sub-screen positioning information to control the LED sub-screens to arrange themselves according to their corresponding matrix numbers. Automatic identification and arrangement of the LED sub-screens reduces manual operation and improves arrangement efficiency, thereby enhancing the efficiency of LED screen relocation. The system also assembles the LED sub-screens according to their corresponding matrix numbers, and after installation, checks the flatness of the spliced ​​joints. Based on the results, the positions of the LED sub-screens are fine-tuned to ensure the flatness meets requirements, improving the accuracy of LED screen relocation.

[0008] In a preferred embodiment, this application can be further configured as follows: the preprocessing of the LED sub-screens and the matrix numbering of the LED sub-screens in sequence specifically include: The LED sub-screens are respectively installed on their corresponding automated mobile bases; Prefabricated connectors are installed on all LED sub-screens, and all LED sub-screens are matrix-numbered according to the order of the prefabricated connectors. The prefabricated connectors are used to install on the LED sub-screens to limit movement when splicing and installing the LED sub-screens.

[0009] By adopting the above technical solution, LED sub-screens are installed one by one on their corresponding automated mobile bases. Pre-designed prefabricated connectors are installed on all LED sub-screens, and all LED sub-screens are numbered according to the connection sequence of the prefabricated connectors, so that they form a matrix, which facilitates the subsequent splicing and installation of LED sub-screens and improves the efficiency of LED screen mobile installation.

[0010] In a preferred embodiment, this application can be further configured as follows: obtaining the sub-screen positioning information corresponding to all the LED sub-screens and analyzing the sub-screen positioning information to generate a sub-screen positioning signal specifically includes: Obtain the sub-screen positioning information of all the LED sub-screens, and calculate the distance error between the sub-screen positioning information and the installation destination information; When the distance error corresponding to all the LED sub-screens is less than the preset value, a sub-screen positioning signal is generated.

[0011] By adopting the above technical solution, the positioning device integrated into the LED sub-screen obtains the sub-screen positioning information, calculates the distance error between the sub-screen positioning information and the installation destination information, and generates a sub-screen positioning signal when the distance error between all LED sub-screens and the installation destination information is less than a preset value. It automatically determines whether all LED sub-screens have reached the predetermined installation position and restricts all arriving LED sub-screens within a preset range, which facilitates the subsequent installation of LED screens and improves the efficiency of LED screen mobile installation.

[0012] In a preferred embodiment, this application can be further configured as follows: the installation of the LED sub-screens according to the matrix numbering, and the detection and fine-tuning of the splicing flatness of the LED sub-screens, specifically include: The corresponding sub-screen arrangement instruction is generated according to the matrix number, and the sub-screen arrangement instruction is used to control the robotic arm to arrange the LED sub-screens according to the matrix number; The mobile base photographic image is acquired again and identified to locate the detailed position information of the prefabricated connector installed on the LED sub-screen; Based on the detailed location information, a sub-screen splicing instruction is generated to control the splicing and installation of the LED sub-screens; After the splicing is completed, the flatness of the LED sub-screen is checked and fine-tuned.

[0013] By adopting the above technical solution, the system generates corresponding sub-screen arrangement instructions based on the matrix numbers previously assigned to the LED sub-screens, controlling the arrangement of the LED sub-screens according to the matrix numbers. It acquires and identifies real-time photographic images of the moving base, locates the positions of the prefabricated connectors, generates detailed position information for the prefabricated connectors, compares the detailed position information of the prefabricated connectors at corresponding positions on two adjacent LED sub-screens with the same matrix number, and moves the LED sub-screens according to the positional differences to connect the corresponding prefabricated connectors on the two LED sub-screens. This allows the two LED sub-screens to be spliced ​​and installed together. After all LED sub-screens are spliced ​​and installed, the system checks the splicing flatness of the installed LED sub-screens. Based on the test results, it makes corresponding fine adjustments to the spatial positions of the LED sub-screens to ensure that the splicing flatness of the installed LED sub-screens meets the requirements, thus improving the accuracy of LED screen movement and installation.

[0014] In a preferred embodiment, this application can be further configured as follows: after the determination of splicing is completed, the splicing flatness of the LED sub-screen is detected and fine-tuned, specifically including: Obtain the splicing judgment duration threshold and monitor the instruction generation time of the sub-screen splicing instruction in real time. Analyze and calculate the blank duration of the sub-screen splicing instruction based on the instruction generation time. The blank duration refers to the pause duration in the sub-screen splicing instruction generation process. When the blank duration exceeds the splicing judgment duration threshold, a sub-screen splicing flatness detection is performed. Based on the detection result of the sub-screen splicing flatness detection, a sub-screen fine-tuning signal is generated. The sub-screen fine-tuning signal is used to control the position of the LED sub-screen to be finely adjusted according to the detection result.

[0015] By adopting the above technical solution, a time range for determining whether splicing is complete is obtained, namely the splicing judgment time threshold. The time of the last sub-screen splicing command is monitored in real time, and then analyzed and calculated to obtain the time when the sub-screen splicing command stops generating, namely the blank time. When the blank time when the sub-screen splicing command stops generating is greater than the splicing judgment time threshold, it is determined that the LED sub-screen has been initially spliced. The splicing flatness of the LED sub-screen is detected, the LED sub-screens with substandard splicing flatness are located, and their spatial positions are finely adjusted accordingly to ensure that the splicing flatness of the LED sub-screen after installation meets the requirements, further improving the accuracy of LED screen mobile installation.

[0016] In a preferred embodiment, this application can be further configured such that: the automatic navigation movement based on the installation destination information to transport the LED sub-screen to the location corresponding to the installation destination information further includes: During transportation, the difference value of the sub-screen positioning information is calculated in real time to generate sub-screen range information; When the sub-screen range information exceeds a preset range threshold, the LED sub-screen that is out of range sends a sub-screen loss alarm signal and corresponding sub-screen location information to the user.

[0017] By adopting the above technical solution, during transportation, the difference value of the sub-screen positioning information is calculated in real time to obtain the distance between LED sub-screens. The sub-screens are then sorted according to their distances to obtain the distance between the two farthest LED sub-screens, generating sub-screen range information. When the sub-screen range information exceeds a pre-set range threshold in the system, it is determined that one of the two corresponding LED sub-screens is at risk of being lost. This is then combined with other sub-screen range information to determine which LED sub-screen is at risk of being lost. The LED sub-screen at risk of being lost sends a sub-screen loss alarm signal and the corresponding sub-screen positioning information to the user, which is convenient for locating and finding the lost LED sub-screen, thereby improving the safety of moving and installing LED screens.

[0018] The second objective of this invention is achieved through the following technical solution: A mobile installation device for an LED screen, the mobile installation device for an LED screen comprising: The sub-screen numbering module is used to preprocess LED sub-screens and number them in a matrix according to their order. The sub-screen delivery module is used to obtain installation destination information and automatically navigate and move according to the installation destination information to deliver the LED sub-screen to the location corresponding to the installation destination information. The positioning confirmation module is used to acquire the sub-screen positioning information corresponding to all the LED sub-screens and analyze the sub-screen positioning information to generate a sub-screen positioning signal. The sub-screen arrangement module is used to acquire a photographic image of the moving base when the sub-screen positioning signal is triggered, identify the photographic image of the moving base and arrange the LED sub-screens according to the corresponding matrix number in combination with the sub-screen positioning information; The splicing and installation module is used to splice and install the LED sub-screens according to the matrix number, and to detect and fine-tune the splicing flatness of the LED sub-screens.

[0019] By adopting the above technical solution, pre-designed connectors are installed on the LED sub-screen. These connectors are arranged in a certain order, and the LED sub-screen is matrix-numbered according to the arrangement of these connectors to facilitate subsequent splicing and installation of the LED sub-screen, thus improving the efficiency of LED sub-screen mobile installation. The system acquires the user-preset installation destination information, and the automated mobile base equipped with the LED sub-screen uses automatic navigation technology to automatically navigate and move the LED sub-screen to the target location, saving manual operation time and effort and improving the efficiency of LED sub-screen mobile installation. The positioning system integrated into the LED sub-screen acquires the LED sub-screen's positioning information, compares the current positioning information with the installation destination information, and determines whether the LED sub-screen is in place. If the positioning conditions are met, a corresponding sub-screen positioning signal is generated, automatically determining the LED sub-screen's position. The system ensures that all LED sub-screens reach their designated installation positions and confines them within a preset range, facilitating subsequent installation and improving the efficiency of LED screen relocation. When a sub-screen is triggered into position, the system acquires images from cameras integrated on the automated mobile base, performs image recognition and processing, and combines real-time sub-screen positioning information to control the LED sub-screens to arrange themselves according to their corresponding matrix numbers. Automatic identification and arrangement of the LED sub-screens reduces manual operation and improves arrangement efficiency, thereby enhancing the efficiency of LED screen relocation. The system also assembles the LED sub-screens according to their corresponding matrix numbers, and after installation, checks the flatness of the spliced ​​joints. Based on the results, the positions of the LED sub-screens are fine-tuned to ensure the flatness meets requirements, improving the accuracy of LED screen relocation.

[0020] The above-mentioned objective three of this application is achieved through the following technical solution: A computer device includes a memory, a processor, and a computer program stored in the memory and executable on the processor, wherein the processor executes the computer program to implement the steps of the above-described LED screen mobile installation method.

[0021] The fourth objective of this application is achieved through the following technical solution: A computer-readable storage medium storing a computer program that, when executed by a processor, implements the steps of the above-described LED screen mobile installation method.

[0022] In summary, this application includes at least one of the following beneficial technical effects: 1. Install each LED sub-screen onto its corresponding automated mobile base. Install pre-designed prefabricated connectors on all LED sub-screens and number them according to the connection sequence of the prefabricated connectors to form a matrix, which facilitates the subsequent splicing and installation of LED sub-screens. The positioning device integrated on the LED sub-screen obtains the sub-screen positioning information and calculates the distance error between the sub-screen positioning information and the installation destination information. When the distance error between all LED sub-screens and the installation destination information is less than the preset value, a sub-screen positioning signal is generated. The system automatically determines whether all LED sub-screens have reached the predetermined installation position and restricts all arriving LED sub-screens within a preset range, which facilitates the subsequent installation of LED screens and improves the efficiency of LED screen mobile installation. 2. Based on the matrix numbers previously assigned to the LED sub-screens, the system generates corresponding sub-screen arrangement instructions to control the arrangement of the LED sub-screens according to the matrix numbers. It acquires and identifies real-time moving base photographic images, locates the positions of the prefabricated connectors, generates detailed position information for the prefabricated connectors, compares the detailed position information of the prefabricated connectors at corresponding positions on two adjacent LED sub-screens with the same matrix number, and moves the LED sub-screens according to the positional differences to connect the corresponding prefabricated connectors on the two LED sub-screens. This allows the two LED sub-screens to be spliced ​​and installed together. The system then obtains data to determine whether splicing is possible. The completion time range, i.e. the splicing judgment time threshold, is monitored in real time at the time of the last sub-screen splicing instruction generation. The time for the sub-screen splicing instruction to stop generating is then analyzed and calculated to obtain the blank time. When the blank time for the sub-screen splicing instruction to stop generating is greater than the splicing judgment time threshold, it is determined that the LED sub-screen has been initially spliced. The splicing flatness of the LED sub-screen is detected, the LED sub-screens with substandard splicing flatness are located, and their spatial positions are finely adjusted accordingly to ensure that the splicing flatness of the LED sub-screen after installation meets the requirements, further improving the accuracy of LED screen mobile installation. 3. During transportation, the difference value of the sub-screen positioning information is calculated in real time to obtain the distance between LED sub-screens. The sub-screens are sorted according to their distance and the distance between the two farthest LED sub-screens is obtained, generating sub-screen range information. When the sub-screen range information exceeds the range threshold preset in the system, it is determined that one of the two corresponding LED sub-screens is at risk of being lost. Combined with other sub-screen range information, it is determined which LED sub-screen is at risk of being lost. The LED sub-screen at risk of being lost sends a sub-screen loss alarm signal and the corresponding sub-screen positioning information to the user, which is convenient for locating and finding the lost LED sub-screen, thereby improving the safety of LED screen relocation and installation.

[0031] The present application will be further described in detail below with reference to the accompanying drawings.

[0032] In one embodiment, such as Figure 1 As shown, this application discloses a method for moving and installing an LED screen, which specifically includes the following steps: S10: Preprocess the LED sub-screens and number them in matrix order.

[0033] In this embodiment, LED sub-screens refer to the small LED screen units that make up the large LED screen.

[0034] Specifically, some pre-designed connectors are installed on the LED sub-screen. These connectors are arranged in a certain order, and the LED sub-screen is matrix-numbered according to the arrangement of these connectors. The function of these pre-made connectors is to limit the LED sub-screen during splicing and installation, ensuring that the LED sub-screen is correctly positioned and neatly arranged during splicing.

[0035] S20: Obtain installation destination information and automatically navigate and move the LED sub-screen to the location corresponding to the installation destination information.

[0036] In this embodiment, the installation destination information refers to the location information where the large LED screen to be spliced ​​needs to be installed.

[0037] Specifically, the system obtains the user's preset installation destination information, and the automated mobile base equipped with the LED sub-screen moves the LED sub-screen to the target location using automatic navigation technology, such as inertial navigation or GPS navigation, based on the obtained installation destination information.

[0038] S30: Obtain the sub-screen positioning information corresponding to all LED sub-screens, and analyze the sub-screen positioning information to generate a sub-screen positioning signal.

[0039] In this embodiment, the sub-screen positioning information refers to the real-time positioning information corresponding to each LED sub-screen, and the sub-screen in place signal refers to the information indicating that the corresponding sub-screen has been transported to the installation destination.

[0040] Specifically, the positioning information of the LED sub-screen is obtained by the positioning system integrated into the LED sub-screen. The difference between the current positioning information and the installation destination information is compared to determine whether the LED sub-screen is in place. If the placement conditions are met, a corresponding sub-screen placement signal is generated.

[0041] S40: When the sub-screen positioning signal is triggered, the moving base photographic image is acquired, the moving base photographic image is identified, and the LED sub-screens are arranged according to the corresponding matrix number in combination with the sub-screen positioning information.

[0042] In this embodiment, the mobile base photographic image refers to the image captured by the camera integrated on the automated mobile base.

[0043] Specifically, when the sub-screen is triggered to take position, the system acquires the image captured by the camera integrated on the automated mobile base, performs image recognition and processing, and controls the LED sub-screens to arrange themselves according to the corresponding matrix number in combination with the real-time sub-screen positioning information.

[0044] S50: Install LED sub-screens according to the matrix number, and check and fine-tune the flatness of the LED sub-screen splicing.

[0045] Specifically, the LED sub-screens are spliced ​​and installed in the order of their corresponding matrix numbers. After installation, the flatness of the spliced ​​LED sub-screens is tested, and the positions of the LED sub-screens are fine-tuned based on the test results to ensure that the flatness of the spliced ​​LED sub-screens meets the requirements.

[0046] In one embodiment, such as Figure 2As shown, in step S10, the LED sub-screens are preprocessed and numbered in a matrix according to their order. This specifically includes: S11: Install the LED sub-screens on their respective automated mobile bases.

[0047] In this embodiment, an automated mobile base refers to a base that can move automatically according to navigation information.

[0048] Specifically, the system controls the robotic arm to install the LED sub-screens one by one onto the corresponding automated mobile base.

[0049] S12: Install prefabricated connectors on all LED sub-screens and number all LED sub-screens in a matrix according to the order of the prefabricated connectors. The prefabricated connectors are used to install on the LED sub-screens to limit movement when splicing and installing the LED sub-screens.

[0050] Specifically, pre-designed prefabricated connectors, including mounting holes and fixing slots, are installed on all LED sub-screens. All LED sub-screens are numbered according to the connection sequence of the prefabricated connectors, so that they form a matrix. The prefabricated connectors are used to fix the position of the LED sub-screens during the splicing process.

[0051] In one embodiment, such as Figure 3 As shown, in step S30, the sub-screen positioning information corresponding to all LED sub-screens is obtained and analyzed to generate a sub-screen positioning signal, specifically including: S31: Obtain the sub-screen positioning information of all LED sub-screens and calculate the distance error between the sub-screen positioning information and the installation destination information.

[0052] Specifically, the positioning information of the sub-screen is obtained by a positioning device integrated into the LED sub-screen, and the distance error between the sub-screen positioning information and the installation destination information is calculated, such as "3m".

[0053] S32: When the distance error corresponding to all LED sub-screens is less than the preset value, a sub-screen positioning signal is generated.

[0054] Specifically, when the distance error between all LED sub-screens and the installation destination information is less than a preset value such as "10m", it is determined that the LED sub-screen has reached the expected installation position, and a sub-screen positioning signal is generated.

[0055] In one embodiment, such as Figure 4 As shown, in step S50, the LED sub-screens are spliced ​​and installed according to the matrix number, and the flatness of the LED sub-screen splicing is detected and fine-tuned. This specifically includes: S51: Generate corresponding sub-screen layout instructions based on matrix numbers. Sub-screen layout instructions are used to control the robotic arm to arrange LED sub-screens according to matrix numbers.

[0056] Specifically, the system generates corresponding sub-screen arrangement instructions based on the matrix numbers previously assigned to the LED sub-screens, which instruct the robotic arm on the automated mobile base to arrange the LED sub-screens according to the matrix numbers. For example, the sub-screen arrangement instruction corresponding to the LED sub-screen with matrix number (1,2) controls the robotic arm on the corresponding automated mobile base to make the LED sub-screen not move horizontally, but move vertically to a height of 2 units.

[0057] S52: Acquire and identify the photographic image of the moving base again to locate the detailed position information of the prefabricated connector installed on the LED sub-screen.

[0058] Specifically, real-time photographic images of the moving base are acquired and identified, the positions of the prefabricated connectors are located, and detailed location information of the prefabricated connectors is generated.

[0059] S53: Generate sub-screen splicing instructions based on detailed location information to control the splicing and installation of LED sub-screens.

[0060] In this embodiment, the sub-screen splicing instruction refers to the instruction used to control the robotic arm to splice and install the LED sub-screens.

[0061] Specifically, the detailed position information of the prefabricated connectors at corresponding positions of two adjacent LED sub-screens with matrix numbers is compared, and the robotic arm is controlled to move the LED sub-screens according to the position difference, so that the prefabricated connectors at corresponding positions on the two LED sub-screens are connected, thereby splicing and installing the two LED sub-screens together.

[0062] S54: After the splicing is completed, the flatness of the LED sub-screen is checked and fine-tuned.

[0063] Specifically, after all LED sub-screens have been spliced ​​and installed, the system checks the flatness of the spliced ​​LED sub-screens and controls the robotic arm to make corresponding fine adjustments to the spatial position of the LED sub-screens based on the test results.

[0064] In one embodiment, such as Figure 5 As shown, in step S54, after the splicing is completed, the flatness of the LED sub-screen is detected and fine-tuned, specifically including: S541: Obtain the splicing judgment duration threshold and monitor the instruction generation time of the sub-screen splicing instruction in real time. Analyze and calculate the blank duration of the sub-screen splicing instruction based on the instruction generation time. The blank duration refers to the pause duration in the sub-screen splicing instruction generation process.

[0065] In this embodiment, the splicing judgment duration threshold refers to the duration range used to determine whether splicing is complete; the instruction generation time refers to the time when the last sub-screen splicing instruction was generated.

[0066] Specifically, the time range used to determine whether the splicing is complete is obtained, i.e. the splicing judgment time threshold. The time of the last sub-screen splicing instruction is monitored in real time, and then analyzed and calculated to obtain the time when the sub-screen splicing instruction stops generating, i.e. the blank time. For example, if the instruction generation time is "12:00:10" and the current time is "12:01:30", then the blank time is "80s".

[0067] S542: When the blank duration is greater than the splicing judgment duration threshold, the sub-screen splicing flatness is detected. Based on the detection result of the sub-screen splicing flatness, a sub-screen fine-tuning signal is generated. The sub-screen fine-tuning signal is used to control the position of the LED sub-screen to be finely adjusted according to the detection result.

[0068] Specifically, when the blank duration generated by the sub-screen splicing instruction stops exceeds the splicing judgment duration threshold, such as when the blank duration is "80s" and the splicing judgment duration threshold is "81s", it is determined that the LED sub-screen has been initially spliced. The splicing flatness of the LED sub-screen is detected by laser leveling, the LED sub-screens with substandard splicing flatness are located, and the spatial position of them is finely adjusted by a robotic arm.

[0069] In one embodiment, such as Figure 6 As shown, in step S20, which involves automatic navigation movement based on the installation destination information to transport the LED sub-screen to the location corresponding to the installation destination information, the method further includes: S201: During transportation, the difference value of the sub-screen positioning information is calculated in real time to generate sub-screen range information.

[0070] In this embodiment, the sub-screen range information refers to the distance between two LED sub-screens.

[0071] Specifically, during transportation, the difference in the positioning information of the sub-screens is calculated in real time to obtain the distance between the LED sub-screens and generate sub-screen range information, such as "50m" for one of the sub-screen range information.

[0072] S202: When the sub-screen range information exceeds the preset range threshold, the LED sub-screen that is out of range sends a sub-screen loss alarm signal and the corresponding sub-screen location information to the user.

[0073] In this embodiment, the range threshold refers to the farthest distance range from which the sub-screen is lost; the sub-screen loss alarm signal refers to a signal used to warn the user that the corresponding sub-screen is at risk of being lost.

[0074] Specifically, when the sub-screen range information exceeds the preset range threshold in the system, such as when one of the sub-screen range information is "60m" and the preset range threshold is "50m", it is determined that one of the two corresponding LED sub-screens is at risk of being lost. Then, combined with the range information of other sub-screens, it is determined which LED sub-screen is at risk of being lost. The LED sub-screen at risk of being lost sends a sub-screen loss alarm signal and the corresponding sub-screen location information to the user.

[0075] It should be understood that the sequence number of each step in the above embodiments does not imply the order of execution. The execution order of each process should be determined by its function and internal logic, and should not constitute any limitation on the implementation process of the embodiments of this application.
