Technical Field

During specific splicing, the input card is used for converting the original data of each input source into data which can be processed by exchange; the exchange is used for creating a mapping channel between the input card and the output card under the action of the controller; and then, after relevant data processing is carried out on some input sources by using the output card, the processed data is displayed on the display equipment to complete the splicing function.

Another embodiment of a splicing processor 1000 according to the present invention is an optimized embodiment of the foregoing embodiment, as shown in fig. 2, the main improvement of this embodiment compared with the foregoing embodiment is that the splicing processor includes:

the main control module 1100 includes:

a first communication unit 1110 that acquires the target control instruction;

the first communication unit 1110 transmits the target control instruction to the input processing module 1200 and/or the output processing module 1300.

Specifically, in this embodiment, the target control instruction obtained by the output processing module 1300 may be sent by the connected expansion processing module 1400, or may be sent by the connected main control module 1100. The main control module 1100 plays a role similar to a transfer station, and the main control module 1100 is configured to coordinate and control connection relationships between itself and each of the expansion processing modules 1400, the input processing module 1200, and the output processing module 1300, that is, to control connection states (that is, connection or disconnection) between itself and each of the expansion processing modules 1400, and also to control connection states between itself and each of the output processing module 1300 and the input processing module 1200, where the main control module 1100 sends an acquired target control instruction to the input processing module 1200 connected to the main control module 1100 itself, or the main control module 1100 sends an acquired target control instruction to the output processing module 1300 connected to the main control module 1100, or the main control module 1100 sends an acquired target control instruction to the output processing module 1300 and the input processing module 1200 connected to the main control module 1100. The main control module 1100 may parse the acquired target control command, determine which screen connected output processing module 1300 the target control command is for, if the main control module 1100D is connected to the output processing modules 1300E1, E2, and E3, the user inputs control operation data a in the external device 2000, the control operation data a is for the first image information of the large screen to which the output processing module 1300E2 is connected, the expansion processing module 1400 converts the control operation data a into a corresponding target control command, and sends the target control instruction to the main control module 1100, and the main control module 1100 analyzes the obtained target control instruction, and analyzes that the control operation data a is for the first image information of the large screen connected to the output processing module 1300E2, so that the main control module 1100 can directly forward the target control instruction to the output processing module 1300E 2. If the control operation data a is for the first image information of the large screen to which the output processing modules 1300E1, E2, and E3 are connected, the main control module 1100 may forward the target control command to the output processing modules 1300E1, E2, and E3, respectively. According to the invention, each module is coordinated and controlled through the main control module 1100, repeated sending of the same target control instruction to the input processing module 1200 or the output processing module 1300 can be reduced, and the system pressure of the splicing processor 1000 is reduced.

the input processing module 1200 is connected to the main control module 1100, and acquires the target control instruction; and/or the presence of a gas in the gas,

the input processing module 1200 is connected to the output processing module 1300, and acquires the target control instruction;

the input processing module 1200 includes:

an input unit 1210 that acquires the first image information;

a second communication unit 1220 for acquiring the target control instruction;

the first processing unit 1230 processes the corresponding part of the spatial information in the first image information according to the control information in the target control instruction, so as to obtain corresponding processed first image information.

Specifically, in this embodiment, since the main control module 1100 is respectively connected to each expansion processing module 1400, the input processing module 1200, and the output processing module 1300, that is, the main control module 1100 functions like a transfer station, the main control module 1100 can acquire all target control instructions acquired by each expansion processing module 1400, and also can acquire all first image information acquired by each input processing module 1200, so as to forward the first image information to each output processing module 1300, the input processing module 1200 can acquire the target control instructions by being connected to the main control module 1100, and process the corresponding first image information acquired by itself according to the acquired target control instructions, so as to obtain the processed first image information. The input processing module 1200 may also be connected to the output processing module 1300, acquire a target control instruction from the connected output processing module 1300, and process the corresponding first image information acquired by itself according to the acquired target control instruction to obtain processed first image information.

Wherein, the control information includes editing control, overlay control, rotation control, zooming control, etc., for example, the input processing module 1200 superimposes the first image information with graphics, cursor, or editing characters, etc., in real time, thereby realizing visual operation on the large screen and the source signal source, enhancing visual interactive operation experience, being more intuitive and having stronger interactivity, and because the input processing module 1200 can process the first image information, the first image information can be primarily processed, for example, after the initial first image information is obtained from the image acquisition device 3000 and/or the network address, the preset icon needs to be superimposed on the first image information, the input processing module 1200 superimposes the preset icon on the first image information to obtain the processed first image information, the processed first image information of the preset icon superimposed on the first image information can be transmitted to the output processing module 1300, the processed first image information is processed by the output processing module 1300 two or more times, and no matter what control operation is performed on the processed first image information by the output processing module 1300, the processed first image information obtained by the primary processing by the input processing module 1200 cannot be deleted or replaced unless all the output processing modules 1300 that acquire the processed first image information are edited at the same position, and any one of the output processing modules 1300C1 that acquire the processed first image information is not edited at the same position, and the preset icon superimposed by the input processing module 1200 is still displayed by the screen connected to the output processing module 1300C 1. Illustratively, the video image, which is the first image information acquired by the camera F that shoots the scene of the hall, needs to be marked as the hall, so that the user can conveniently record and look up the video image, and the acquired video image is subjected to text superposition through the input processing module 1200 of the camera F, that is, the text icon of the hall is superposed on the video image, so that the displayed video image is the video image marked with the hall when the large screen display is performed. If the output processing modules 1300 are used for superposition, when the large-screen display is carried out, all the output processing modules 1300 connected with the large screen are required to carry out character superposition, the processing resources of all the output processing modules 1300 are wasted, and the processing and editing efficiency is reduced.

2.2, the input processing module 1200 is connected with the image capturing device 3000 by a wire through a connecting wire, and acquires the first image information from the connected image capturing device 3000.

Specifically, the input processing module 1200 can acquire the first image information from any one or more of the image capturing device 3000 (e.g., a camera, a video camera, etc.) and a network address. Illustratively, when the input processing module 1200 is connected to several image capturing devices 3000 such as cameras, the input processing module 1200 obtains the first image information from the camera, the expansion processing module 1400 obtains the control operation data input by the user on the external device 2000, converts the control operation data into the target control command, the target control instruction is sent to the input processing module 1200 through the main control module 1100 or the output processing module 1300, the input processing module 1200 obtains the target control instruction, then the input processing module 1200 analyzes the target control instruction to obtain control operation data, and the input processing module 1200 rotates and moves the correspondingly connected camera to the position (direction and position) required by the user according to the control operation data, so that the camera can shoot surrounding scenes more comprehensively and effectively to obtain first image information required by the user.

For example, in the operation of capturing a suspect in public security, a large number of suspicious images preliminarily screened by artificial intelligence are called and displayed on a large screen, and are respectively displayed on seat screens (such as computers) corresponding to the work seats of various workers, and different workers carry out secondary manual comparison and verification on each large screen or seat screen, if no suspicious point exists, the workers can carry out operation (such as mouse click operation and keyboard key operation) division through a keyboard or a mouse connected with the expansion processing module 1400 of the splicing processor 1000, if the suspicious point exists, character marking can be added through a mouse mark or a key, and meanwhile, control operation data of the control camera can be input through the keyboard or the mouse, the control operation data is transmitted to the corresponding expansion processing module 1400, the expansion processing module 1400 transmits the control operation data to the main control module 1100 and/or the corresponding output processing module 1300, the input processing module 1200 obtains the control operation data from the main control module 1100 and/or the correspondingly connected output processing module 1300, and the input processing module 1200 triggers the traffic camera to rotate to a proper position and direction or focus according to the control operation data, so that the public security can conveniently perform secondary tracking and positioning on the suspect.

Illustratively, if a user uses a touch pad to click a certain position, that is, control operation data, a highlighted selection frame layer is superimposed on a video to be displayed on a control screen, an expansion processing module 1400 connected to the touch pad converts the control operation data into a target control instruction including spatial information and control information, the expansion processing module 1400 sends the target control instruction to a main control module 1100 and/or an output processing module 1300 connected to the expansion processing module 1400 through a network, after receiving the target control instruction, the main control module 1100 and/or the output processing module 1300 connected to the expansion processing module 1400 forwards the target control instruction to an input processing module 1200 connected to the main control module 1100 and/or the expansion processing module 1400, and each output processing module 1300 or input processing module 1200 parses the target control instruction to obtain corresponding control information, The spatial information corresponding to the control information, each of the output processing modules 1300 or the input processing module 1200 determines whether the spatial information is in its corresponding display region, and determines whether the display region needs to execute the control information corresponding to the target control command, if the spatial information is in the display area of the user and the control information corresponding to the target control instruction is executed, the highlighted selection frame layer is displayed in an overlapping mode at the screen position (spatial information) corresponding to the clicking position (coordinate information) of the user on the touch screen, if the coordinate information is located in the display area of the display device 4000 to which a certain output processing module 1300M is correspondingly connected, the output processing module 1300M generates a highlighted selection frame layer in real time to be superimposed on the spatial position of the first image information displayed by the display device 4000 connected with the output processing module 1300M. If the user uses the touch pad to double-click a certain position, based on the above single-click operation, the area selected by the highlighted selection frame layer is amplified after the highlighted selection frame layer is superimposed, and the event is notified to the main control module 1100 and other input processing modules 1200 and output processing modules 1300 through the bus. In addition, a user can also generate a cursor displayed on the large screen through the touch pad, and in the moving process of the user on the touch pad, the output processing module 1300 connected with the expansion processing module 1400 corresponding to the touch pad can perform graphic or text overlapping operation in real time according to the movement of the user, so that the large screen connected with the output processing module 1300 can generate interactive effects such as window frame flickering and coordinate real-time display, and the like, and the user feels that the operation on the touch pad is visual and intuitive operation on the content displayed on the large screen.

The output processing module 1300 processes the acquired first image information according to the target control instruction to obtain corresponding second image information, and then sends the second image information to a display device (such as an LED display screen, a numerical control display screen, or the like having a display screen) connected to the output processing module 1300, and displays the second image information through the display device, and because the second image information displayed by the display device is real-time, visual and intuitive operation on the first image information according to the control operation data input by the user in real time on the external device 2000.

The unique identification number and the priority between the extension processing modules 1400 are set according to negotiation between the extension processing modules, and a large screen can be flexibly selected and controlled by a user, so that heavy workload caused by setting the unique identification number and the priority for the extension processing modules 1400 in advance is avoided, and user experience is guaranteed.

For example, in an application scenario of user interactive operation, such as under a condition that a splicing processor 1000 is used to manage a large number of operator operating seats, the scenario mainly aims at a large number of operators in some command and dispatch centers, an extension processor may be connected to each seat, each extension processor may be connected to various external devices 2000 such as a mouse, a keyboard, or a stylus pen, and each operator may operate one or more screens corresponding to the seat in a large screen, and may operate independently of each other. Meanwhile, the expansion processing module 1400 of the present invention can be connected not only to the main control module 1100 through a network, but also to the output processing module 1300 having a network connection function, so that when the external device 2000 inputs control operation data, the expansion processing module 1400 connected to the external device 2000 controls the contents displayed on the output screen corresponding to the output processing module 1300 connected to the expansion processing module 1400 to be superimposed, or when the video contents processed in the output processing module 1300 are superimposed, the processing burden is only on the output processing module 1300, and in the seat management application in the field of large screen application, most of the control of the mouse keyboard touch screen and the like corresponds to some output screens, and the operation on the full screen is rather small, which is more favorable for reducing the burden of the splicing processor 1000, and improving the response speed of the interactive operation between the user and the large screen, hardware overhead is reduced.

The splicing processor 1000 with the above functions can be used in the visual command of a large military command center or an actual combat training center, the command center is provided with a large display screen, each officer and high-level commander are provided with a display and a set of keyboard mouse and drawing board in front of the seat of each officer, the keyboard mouse and the drawing board of each seat are connected to an extension processing module 1400 equipped on the seat, the splicing processor 1000 is connected with all the display screens, each officer carries out the visual command (battlefield image and computer image) of the army with the authority, the operations such as the views and the sizes of a plurality of battlefield images can be changed by drawing the drawing board, the operation of any one or a plurality of seats can be displayed on the large screen, each officer has the operation authority to the corresponding seat, and the seat corresponding to the high-level director has the management authority to operate any one of the screens of the seats or the large screen, which can be realized by defining the authority and the priority for a plurality of the extended processing modules 1400. In addition, if the input processing module 1200 is connected to the server to obtain the first image information, i.e., the battlefield diagram, the connection combination key of the high-level commander on a certain battlefield diagram can be converted into the graphic superposition of the battlefield diagram in the input processing module 1200, for example, the connection combination key of a certain battlefield diagram can be converted into the connection combination key of the input processing module 1200 to superpose a fire striking red arrow graphic on the battlefield diagram, meanwhile, the server is also connected with the input processing module 1200 through the network to obtain the target control instruction of the high-level commander, and the server issues the target control instruction to the military command system through the network, so that the high-level commander issues the fire striking instruction, and the fire striking instruction is that a fire striking red arrow graphic area superposed on the battlefield diagram is a striking range. That is to say, the splicing processor 1000 has the capability of converting the visual target control instruction into other control information or instruction and combining with the overlay graph to realize the virtualized display and the visual real control, and the user can operate the binding capability of the target control instruction through the external device 2000 to meet the requirements of different industries.

Illustratively, if a plurality of users use a plurality of expansion processing modules 1400, for example, user 1 connects an expansion processing module 1400S1 with a mouse, expansion processing module 1400S1 connects an output processing module 1300X1, user 2 connects an expansion processing module 1400S2 with a tablet, and expansion processing module 1400S2 connects an output processing module 1300X 2. The two expansion processing modules 1400 firstly obtain a unique identification number through network negotiation, convert the unique identification number and the received mouse or handwriting board operation information into a target control instruction which can be recognized by the input processing module 1200 and the output processing module 1300 of the splicing processor 1000, the two expansion processing modules 1400 send the target control instruction to the connected main control module 1100 and the output processing module 1300 through the network, after the main control module 1100 and the output processing module 1300 receive the target control instruction, the target control instruction is sent to each input processing module 1200 and the output processing module 1300, the MCU or FPGA on each input processing module 1200 and output processing module 1300 judges whether the position of the space coordinate in the target control instruction is in the display area where the MCU is located, and judges whether the display area receives and executes the control information in the target control instruction, if both are satisfied, the operation display is performed in the display area. If, for the output processing module 1300X1, the spatial information corresponding to the mouse operated by the user 1 is located at the edge of a signal window of the display area responsible for the output processing module 1300X1, the output processing module 1300X1 generates a highlighted selection frame layer in real time to be superimposed on the signal window, and generates a cursor prompt that can be pulled by the user at the same time, so that the user 1 can click and pull the selected cursor through the mouse, thereby implementing interactive operation of scaling the size of the window. If the space information corresponding to the handwriting pad operation operated by the user 2 is located in the display area of the output processing module 1300X2 for the output processing module 1300X2, the output processing module 1300X2 generates a graphic overlay track dotted line in real time, and the user 2 can draw on a large screen through the drawing operation of the handwriting pad. In this embodiment, the user has corresponding visual display to control the image information on the large screen through the operation of the external device 2000. The operations of two or even multiple users can be independent or related to each other, the expansion processor can support simultaneous interactive operation of multiple users through a network, and although each of the input processing module 1200 and the output processing module 1300 receives a large number of target control instructions, only the operations related to the display area and the image information corresponding to each of the input processing module 1200 and the output processing module 1300 need to be executed, and the operation of a larger display area and more image information can be realized by increasing the number of the input processing module 1200 and the output processing module 1300, so that the splicing processor 1000 of the present invention can adapt to the interactive capability of the operation graphics of different scales.

In all the above embodiments, the expansion processing module 1400 is connected to the output processing module 1300 and the main control module 1100 through a network; the input processing module 1200 is connected to the main control module 1100 and the output processing module 1300 through a bus.

The following description will be made based on all the above embodiments by way of example:

The expansion processing module 1400 may access the external device 2000 with the interactive operation function, such as a touch pad, a touch screen, a writing board, a mouse, a keyboard, and the like, which have the interactive function, and may further output the received image and control signal processed inside the splicing processor 1000 to the display, the expansion processing module 1400 may convert control operation data (such as a click position of a mouse at the current time, or a key depression position at the current time or a multi-point touch operation behavior of the touch screen) generated by the external device 2000 accessed by the expansion processing module 1400 to obtain a target control instruction, and transmit the target control instruction to other expansion processing modules 1400, the main control module 1100, and the output processing module 1300 having the network connection, where the input processing module 1200 and the output processing module 1300 both have a function of generating video overlay graphics and text in real time, and the input processing module 1200 and the output processing module 1300 have a function of displaying control information transmitted from the expansion processing module 1400 and the main control module 1100 in real time And controlling respective video superposition graphic operation, cursor and character generation operation and cursor and character change operation, thereby realizing visual and graphical operation on large screen and signal source content.

If the main control module 1100 and the connected output processing module 1300 both obtain the target control instruction, the main control module 1100 and the connected output processing module 1300 forward the obtained target control instruction to each input processing module 1200, the output processing module 1300 and the main control module 1100, and each input processing module 1200 and the output processing module 1300 generate and change the overlay graphics, the cursor and the characters for the corresponding video according to the target control instruction.

Each input processing module 1200 of the present invention performs editing operation processing on the first image information according to the target control instruction, and the user can perform interactive control on the content of the first image information, for example, when the target control instruction is to superimpose a graphic, a cursor, or a character on the first image information, the user can perform visual and graphical interactive control on the content of the first image information, that is: the operation processing of graphics such as overlay graphics is converted into processing and control of signal content, for example, drawing a closed graphic such as a circle by using a writing board can correspond to matting the content in the graphic, and for example, if the overlay is a hand-shaped cursor, pressing a certain key and moving the cursor can be defined as picture content translation.

Specifically, in this embodiment, the steps S110, S120 and S200 are not in sequence, and the step S110, the step S120 and then the step S200 may be performed first, or the step S200 and then the steps S110 and S120 may be performed first. The external device 2000 includes a touch pad, a keyboard, a mouse, a writing pad, a touch screen, and other devices having an interactive operation function, a user operates on the external device 2000, the external device 2000 can obtain control operation data corresponding to the user operation, the external device 2000 is connected to the splicing processor 1000 by a wire through a connection line, or the external device 2000 is wirelessly connected to the splicing processor 1000 through a network, the external device 2000 transmits the acquired control operation data to the splicing processor 1000, the splicing processor 1000 converts the acquired control operation data, namely, the operation information in the control operation data is matched with the control instruction list to obtain the corresponding control information, and mapping coordinate information corresponding to the operation information in the control operation data to obtain corresponding spatial information, wherein the obtained control information and spatial information are the target control instruction.

Specifically, the first image information can be acquired from any one or more of the image capture device 3000 (such as a camera, and the like) and a network address. Illustratively, when the splicing processor 1000 is connected to the image capturing devices 3000 such as a plurality of cameras, the splicing processor 1000 obtains first image information from the cameras, obtains control operation data input by a user on the external device 2000, converts the control operation data into a target control instruction, and then the splicing processor 1000 analyzes the target control instruction to obtain the control operation data, and rotates and moves the correspondingly connected cameras to a position (direction and position) required by the user according to the control operation data, so that the cameras can more comprehensively and effectively shoot surrounding scenes to obtain the first image information required by the user.

Illustratively, the video image, which is the first image information acquired by the camera F that shoots the scene of the hall, needs to be marked as the hall, so that the user can conveniently record and look up the video image, and the acquired video image is subjected to text superposition through the input processing module 1200 of the camera F, that is, the text icon of the hall is superposed on the video image, so that the displayed video image is the video image marked with the hall when the large screen display is performed. If the output processing modules 1300 are used for superposition, when the large-screen display is carried out, all the output processing modules 1300 connected with the large screen are required to carry out character superposition, the processing resources of all the output processing modules 1300 are wasted, and the processing and editing efficiency is reduced.

The unique identification number and the priority between the extension processing modules 1400 are set according to negotiation between the extension processing modules, and a large screen can be flexibly selected and controlled by a user, so that heavy workload caused by setting the unique identification number and the priority for the extension processing modules 1400 in advance is avoided, and user experience is guaranteed.

For example, as shown in fig. 1, 2 and 6, the second image information 2 is displayed on the large screen 3, the user makes the output processing module 1300 perform processing operation on the first image information through the external device 2000 to obtain the second image information 2, and the user rotates the switch button to the horizontal right direction at the predefined preset switching area 1, so that the user makes the input processing module 1200 perform operation on the first image information through the external device 2000 to obtain the processed first image information, and the output processing module 1300 performs processing again or does not process the processed first image information to obtain the second image information, and the second image information is output to the large screen through the output processing module 1300 for display. According to the invention, the interactive operation between the input processing module 1200 and the output processing module 1300 and the user can be switched at will according to the operation selection of the user, so that the interactivity is stronger, and the user experience is higher.

It should be noted that the above embodiments can be freely combined as necessary. The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, various modifications and decorations can be made without departing from the principle of the present invention, and these modifications and decorations should also be regarded as the protection scope of the present invention.
