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

[0003] In order to facilitate use in different environments, existing LED display screens are usually equipped with mobile brackets and require manual assistance to move. However, in large outdoor scenes, since large LED display screens are heavy and cannot be moved by simple brackets, they are often moved and installed by large equipment such as take-off and landing vehicles combined with manual adjustment. The moving cost is high, the process is time-consuming, and a long installation and debugging time is required.

[0004] The above-mentioned prior art solutions have the following defects: the efficiency of mobile installation of LED screens is low. Summary of the invention

[0005] In order to improve the efficiency of mobile installation of LED screens, the present application provides a method, device, computer equipment and storage medium for mobile installation of LED screens.

[0006] The above-mentioned invention objective of the present application is achieved through the following technical solutions: A method for mobile installation of an LED screen, the method comprising: Pre-process the LED sub-screens and number the LED sub-screens in matrix order; Acquire installation destination information, and perform automatic navigation movement according to the installation destination information to transport the LED sub-screen to a location corresponding to the installation destination information; Acquire sub-screen positioning information corresponding to all the LED sub-screens, and analyze the sub-screen positioning information to generate a sub-screen in-place signal; When the sub-screen in-place signal is triggered, a mobile base photographic image is acquired, the mobile base photographic image is identified, and the LED sub-screens are arranged according to the corresponding matrix numbers in combination with the sub-screen positioning information; The LED sub-screens are spliced ​​and installed according to the matrix numbers, and the splicing flatness of the LED sub-screens is detected and fine-tuned.

[0007] By adopting the above technical scheme, some pre-designed connectors are installed on the LED sub-screen. These connectors are arranged in a certain order, and the LED sub-screens are matrix-numbered according to the arrangement order of these connectors, so as to facilitate the subsequent splicing and installation of the LED sub-screens, thereby improving the efficiency of the mobile installation of the LED screen; the user's preset installation destination information is obtained, and the automated mobile base equipped with the LED sub-screen uses automatic navigation technology to perform automated navigation and movement according to the obtained installation destination information, so as to transport the LED sub-screen to the target location, thereby saving time and energy for manual operation and improving the efficiency of the mobile installation of the LED screen; the positioning information of the LED sub-screen is obtained through the positioning system integrated in the LED sub-screen, and 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 in-place conditions are met, a corresponding sub-screen in-place signal is generated to automatically determine whether the LED sub-screen is in place. The system can detect whether all LED sub-screens have reached the predetermined installation position, and limit all the arrived LED sub-screens within the preset range, which is convenient for the subsequent installation of LED screens and improves the efficiency of mobile installation of LED screens. When the sub-screen in place signal is triggered, the image captured by the camera integrated on the automated mobile base is obtained, and image recognition and processing are performed. At the same time, the LED sub-screens are controlled to be arranged according to the corresponding matrix numbers in combination with the real-time sub-screen positioning information. By automatically identifying and arranging the LED sub-screens, manual operations are reduced, the efficiency of arrangement is improved, and thus the efficiency of mobile installation of LED screens is improved. The LED sub-screens are spliced ​​and installed in the order of the matrix numbers corresponding to the LED sub-screens, and the splicing flatness of the LED sub-screens after installation is detected after the installation is completed. The position of the LED sub-screen is fine-tuned according to the detection results so that the splicing flatness of the LED sub-screens after installation meets the requirements, thereby improving the accuracy of mobile installation of LED screens.

[0008] In a preferred example, the present application can be further configured as follows: the pre-processing of the LED sub-screens and the matrix numbering of the LED sub-screens in order specifically includes: The LED sub-screens are respectively installed on corresponding automated mobile bases; Prefabricated connectors are installed on all LED sub-screens, and all the LED sub-screens are numbered in a matrix according to the order of the prefabricated connectors. The prefabricated connectors are used to be installed on the LED sub-screens to limit the position when the LED sub-screens are spliced ​​and installed.

[0010] In a preferred example, the present application can be further configured as follows: the sub-screen positioning information corresponding to all the LED sub-screens is obtained, and the sub-screen positioning information is analyzed to generate a sub-screen in-position signal, specifically including: Acquire 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 errors corresponding to all the LED sub-screens are smaller than a preset value, a sub-screen in place signal is generated.

[0011] By adopting the above technical solution, the sub-screen positioning information is obtained through the positioning device integrated on the LED sub-screen, and the distance error between the sub-screen positioning information and the installation destination information is calculated. When the distance errors between all LED sub-screens and the installation destination information are less than the preset value, a sub-screen in-place signal is generated, and it is automatically determined whether the LED sub-screens have reached the predetermined installation position, and all the LED sub-screens that have arrived are restricted within the preset range, which is convenient for the subsequent installation of LED screens and improves the efficiency of the mobile installation of LED screens.

[0013] By adopting the above technical scheme, the system generates corresponding sub-screen arrangement instructions according to the matrix numbers previously assigned to the LED sub-screens, controls the arrangement of the LED sub-screens according to the matrix numbers, obtains and identifies real-time mobile base photographic images, locates the positions of the prefabricated connectors therein, generates detailed position information of the prefabricated connectors, compares the detailed position information of the prefabricated connectors at corresponding positions of two LED sub-screens with adjacent matrix numbers, moves the LED sub-screens according to the position differences, connects the prefabricated connectors at corresponding positions of the two LED sub-screens, and thus splices and installs the two LED sub-screens together. After the system determines that all LED sub-screens have been spliced ​​and installed, it detects the splicing flatness of the installed LED sub-screens, and makes corresponding fine adjustments to the spatial positions of the LED sub-screens according to the detection results, so that the splicing flatness of the LED sub-screens after installation meets the requirements, thereby improving the accuracy of the mobile installation of the LED screen.

When the blank time when the sub-screen splicing instruction stops being generated is greater than the splicing judgment time threshold, it is judged that the LED sub-screen has been preliminarily spliced, the splicing flatness of the LED sub-screen is detected, the LED sub-screen whose splicing flatness does not meet the standard is located, and its spatial position is fine-tuned accordingly, so that the splicing flatness of the LED sub-screen after installation meets the requirements, thereby further improving the accuracy of the mobile installation of the LED screen.

[0016] In a preferred example, the present application may be further configured as follows: the automatic navigation movement is performed according to the installation destination information to transport the LED sub-screen to the location corresponding to the installation destination information, and further includes: During the transportation process, 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 the transportation process, the difference value of the sub-screen positioning information is calculated in real time to obtain the distance between the LED sub-screens, and the distances are sorted to obtain the distance between the two LED sub-screens that are farthest apart, and the sub-screen range information is generated. When the sub-screen range information exceeds the range threshold preset in the system, it is determined that one of the corresponding two LED sub-screens is at risk of loss, and then combined with the other sub-screen range information, it is determined which LED sub-screen is at risk of loss. The LED sub-screen at risk of loss sends a sub-screen loss alarm signal and 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 mobile installation of LED screens.

If the in-place conditions are met, a corresponding sub-screen in-place signal is generated to automatically determine whether the LED sub-screen is in place. The system can detect whether all LED sub-screens have reached the predetermined installation position, and limit all the arrived LED sub-screens within the preset range, which is convenient for the subsequent installation of LED screens and improves the efficiency of mobile installation of LED screens. When the sub-screen in place signal is triggered, the image captured by the camera integrated on the automated mobile base is obtained, and image recognition and processing are performed. At the same time, the LED sub-screens are controlled to be arranged according to the corresponding matrix numbers in combination with the real-time sub-screen positioning information. By automatically identifying and arranging the LED sub-screens, manual operations are reduced, the efficiency of arrangement is improved, and thus the efficiency of mobile installation of LED screens is improved.

[0031] The present application is further described in detail below in conjunction with the accompanying drawings.

[0032] In one embodiment, if Figure 1 As shown, the present application discloses a method for mobile installation of an LED screen, which specifically includes the following steps: S10: Pre-process the LED sub-screens and number the LED sub-screens in matrix order.

[0033] In this embodiment, the LED sub-screen refers 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-screens. These connectors are arranged in a certain order, and the LED sub-screens are matrix numbered according to the arrangement order of these connectors. The function of these prefabricated connectors is to play a limiting role when splicing and installing the LED sub-screens, ensuring that the LED sub-screens are positioned correctly and arranged neatly when splicing.

[0035] S20: Acquire installation destination information, and perform automatic navigation movement according to the installation destination information to transport the LED sub-screen to a position corresponding to the installation destination information.

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

[0037] Specifically, the installation destination information preset by the user is obtained, and the automated mobile base equipped with the LED sub-screen uses automatic navigation technology, such as inertial navigation, GPS navigation, etc., to move the LED sub-screen to the target position according to the obtained installation destination information.

[0038] S30: Obtain sub-screen positioning information corresponding to all LED sub-screens, and analyze the sub-screen positioning information to generate a sub-screen in-place 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 through the positioning system integrated on the LED sub-screen, and 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 in-place conditions are met, a corresponding sub-screen in-place signal is generated.

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

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

[0043] Specifically, when the sub-screen in place signal is triggered, the image captured by the camera integrated on the automated mobile base is acquired, and image recognition and processing are performed. At the same time, the LED sub-screens are controlled to be arranged according to the corresponding matrix numbers in combination with the real-time sub-screen positioning information.

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

[0045] Specifically, the LED sub-screens are spliced ​​and installed in the order of the matrix numbers corresponding to the LED sub-screens, and the splicing flatness of the LED sub-screens after installation is tested. The position of the LED sub-screens is fine-tuned according to the test results so that the splicing flatness of the LED sub-screens after installation meets the requirements.

[0046] In one embodiment, if Figure 2As shown, in step S10, the LED sub-screens are pre-processed and the LED sub-screens are numbered in matrix in order, which specifically includes: S11: Install the LED sub-screens on the corresponding automated mobile bases respectively.

[0047] In this embodiment, the 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 on the corresponding automated mobile bases.

[0049] S12: Prefabricated connectors are installed on all LED sub-screens, and all LED sub-screens are numbered in a matrix according to the order of the prefabricated connectors. The prefabricated connectors are used to be installed on the LED sub-screens to limit the position when the LED sub-screens are spliced ​​and installed.

[0050] Specifically, pre-designed prefabricated connectors, including mounting holes, fixing slots, etc., 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. The prefabricated connectors are used to fix the positions of the LED sub-screens during the splicing process.

[0051] In one embodiment, if Figure 3 As shown, in step S30, the sub-screen positioning information corresponding to all LED sub-screens is obtained, and the sub-screen positioning information is analyzed to generate a sub-screen in-position signal, which specifically includes: S31: Obtain 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 sub-screen positioning information is obtained through a positioning device integrated on 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 errors corresponding to all LED sub-screens are smaller than a preset value, a sub-screen in place signal is generated.

[0054] Specifically, when the distance errors between all LED sub-screens and the installation destination information are 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 in place signal is generated.

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

[0056] Specifically, the system generates corresponding sub-screen arrangement instructions based on the matrix numbers previously assigned to the LED sub-screens, and instructs 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 instructions corresponding to the LED sub-screen with the matrix number (1, 2) control the robotic arm on the corresponding automated mobile base, so that the LED sub-screen does not move horizontally but moves vertically to a height of 2 units.

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

[0058] Specifically, a real-time photographic image of the mobile base is acquired and recognized, the position of the prefabricated connecting parts therein is located, and detailed position information of the prefabricated connecting parts is generated.

[0059] S53: Generate a sub-screen splicing instruction according to the detailed position information to control the splicing installation of the LED sub-screen.

[0060] In this embodiment, the sub-screen splicing instruction refers to an instruction for controlling the robot arm to splice and install the LED sub-screens.

[0061] Specifically, the detailed position information of the prefabricated connecting parts at the corresponding positions of two LED sub-screens with adjacent 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 connecting parts at the corresponding positions on the two LED sub-screens are connected, thereby splicing and installing the two LED sub-screens together.

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

[0063] Specifically, after the system determines that all LED sub-screens are spliced ​​and installed, it detects the splicing flatness of the installed LED sub-screens, and controls the robotic arm to make corresponding fine adjustments to the spatial positions of the LED sub-screens based on the detection results.

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

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

[0066] Specifically, obtain the time range for judging whether the splicing is completed, that is, the splicing judgment time threshold, monitor the time when the last sub-screen splicing instruction is generated in real time, and then perform analysis and calculation to obtain the time when the sub-screen splicing instruction stops being generated, that is, the blank time. For example, if the instruction generation time is "12:00:10" and the current time is "12:01:30", the blank time is "80s".

[0067] S542: When the blank time is longer than the splicing judgment time threshold, a sub-screen splicing flatness detection is performed, and a sub-screen fine-tuning signal is generated according to the detection result of the sub-screen splicing flatness detection. The sub-screen fine-tuning signal is used to control the position of the LED sub-screen to be fine-tuned accordingly according to the detection result.

[0068] Specifically, when the blank time generated by the sub-screen splicing instruction stops being greater than the splicing judgment time threshold, such as the blank time is "80s" and the splicing judgment time threshold is "81s", it is judged that the LED sub-screen has been preliminarily spliced, and the laser leveling method is used to detect the splicing flatness of the LED sub-screen, locate the LED sub-screen whose splicing flatness does not meet the standard, and use a robotic arm to make corresponding fine adjustments to its spatial position.

[0069] In one embodiment, if Figure 6 As shown, in step S20, that is, automatically navigating and moving according to the installation destination information to transport the LED sub-screen to the location corresponding to the installation destination information, it also includes: S201: During the transport process, the difference value of the sub-screen positioning information is calculated in real time to generate the 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 the transportation process, the difference values ​​of the sub-screen positioning information are calculated in real time to obtain the distance between the LED sub-screens, and the sub-screen range information is generated, such as one item of the sub-screen range information is "50m".

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

[0073] In this embodiment, the range threshold refers to the maximum distance range for determining that a sub-screen is lost; and 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 range threshold preset in the system, such as one of the sub-screen range information is "60m" and the preset range threshold is "50m", it is determined that one of the corresponding two LED sub-screens is at risk of loss, and then combined with the other sub-screen range information, it is determined which LED sub-screen is at risk of loss. The LED sub-screen that is at risk of loss sends a sub-screen loss alarm signal and corresponding sub-screen positioning information to the user.

[0075] It should be understood that the size of the serial numbers of the steps in the above embodiments does not mean 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 the present application.
