Description

Technical Field

[0001] The present disclosure relates to the field of image processing technology, and in particular to an image processing method, device and system. Background Art

[0002] With the rapid development of multimedia technology and the widespread application of network technology, people are eager to obtain large-screen display effects, from the establishment of command and monitoring centers to temporary meetings and technical lectures, but traditional displays are difficult to meet people's requirements in this regard. In recent years, the rapidly developed large-screen display system has become an effective way to solve the problem of large-screen display and is very popular.

[0003] In related technologies, such as Figure 1 As shown, the large-screen display system mainly includes a display screen, an image server, a video source acquisition terminal and a control terminal, wherein the display screen includes at least two split screens, and the control terminal, each split screen, and each video source acquisition terminal are connected to the image server. The specific working principle is: the video source acquisition terminal sends the acquired image to the image server, and the image server sends the received image sent by each video source acquisition terminal to the control terminal, and the user typesets the received image on the control terminal, so that the control terminal generates a display instruction according to the user's typesetting and sends it to the image server, and the image server controls each split screen to display according to the display instruction.

[0004] However, in the above technology, a graphics card that supports the split-screen function needs to be plugged into the image server, and usually one graphics card can only support the splicing of three split screens. If the display screen has more split screens, multiple graphics cards need to be plugged into the image server, but the card slots in the image server are limited, which limits the number of split screens that the image server can support, resulting in a narrow application range of the image server. Summary of the invention

[0115] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present disclosure. Instead, they are merely examples of devices and methods consistent with some aspects of the present disclosure as detailed in the appended claims.

[0116] The present disclosure provides an image processing method, which is applied to a server, such as Figure 2a As shown, the data transmission method includes the following steps:

[0117] Step 201: Receive a display instruction.

[0118] The display instruction carries identification information and display area information of at least one image to be displayed; the display area information is used to indicate the position of the image to be displayed on the display screen; and the display screen includes at least two split screens.

[0119] For example, in actual applications, the server is connected to at least one terminal device and at least one acquisition terminal device, and the server is also connected to the control terminal, wherein the acquisition terminal device is used to acquire images and send the acquired images to the server, and the server can receive images sent by each acquisition terminal device; the control terminal is used to receive images sent by the server and display all received images, so that when the user sees the displayed images on the control terminal, the user can determine the images to be displayed on the display screen and the display area of ​​each image to be displayed on the display screen through keyboard and mouse operations or touch operations. The control terminal then generates a display instruction according to the operation actions of the images to be displayed and the display area corresponding to the images to be displayed determined by the user, and sends the display instruction to the server, so that the server receives the display instruction, which carries identification information and display area information of at least one image to be displayed, and the identification information is used to uniquely identify an image to be displayed, and one identification information corresponds to one display area information. The display area information is the specific location information of each image to be displayed on the display screen. Figure 2b Taking four terminal devices, four acquisition terminal devices, and the display screen including four split screens as an example, the split screens are split screen 1, split screen 2, split screen 3 and split screen 4, among which split screen 1 is connected to terminal device 1, split screen 2 is connected to terminal device 4, split screen 3 is connected to terminal device 2, and split screen 4 is connected to terminal device 3.

[0120] For example, the position of each image to be displayed on the display screen may occupy one split screen or multiple split screens, such as Figure 2b As shown, if the image to be displayed is in the middle of the display screen, the image to be displayed occupies the above four split screens; if the image to be displayed is on the left side of the display screen, the image to be displayed may occupy split screen 1 and split screen 3; if the image to be displayed is on the right side of the display screen, the image to be displayed may occupy split screen 2 and split screen 4.

[0121] For example, the display area information may be the coordinate information of each vertex of the image to be displayed. As shown in FIG2c , assuming that the upper left corner of the display screen is the coordinate origin, the horizontal direction is the X axis, and the vertical direction is the Y axis, the image displayed in the display area filled with slashes in FIG2c is image A, and the display area information of image A is ([960, 540], [1920, 540], [960, 810], [1920, 810]); Figure 2d As shown, Figure 2c The image displayed in the display area filled with slashes is image A, and the image displayed in the display area filled with dots is image B. The display area information of image A is ([960, 540], [1920, 540], [960, 810], [1920, 810]), and the display area information of image B is ([720, 0], [1200, 0], [720, 720], [1200, 720]).

[0122] It should be noted that when the server receives an image sent by the acquisition end device, it generates identification information of the image, and then sends the image and the corresponding identification information to the control end, so that when the control end obtains the user's operation action, the display instruction generated carries the identification information of the image to be displayed, which facilitates the server to determine the corresponding image according to the identification information.

[0123] It should be noted that when the control end displays the received image, it can be displayed in the form of the original image or a thumbnail, and there is no limitation on this.

[0124] Furthermore, the display instruction also carries at least one layer identifier of the image to be displayed; the layer identifier is coordinate information perpendicular to the plane of the display screen.

[0125] For example, the user needs to set a layer identifier for each image. The layer identifier is used to record the display level of each image on the display screen, such as Figure 2d As shown, image A and image B have overlapping parts. If the layer identifier corresponding to image A is 0 and the layer identifier corresponding to image B is 1, then the overlapping part finally displayed on the display screen is image B, and the overlapping area of ​​image A is not displayed but covered by the overlapping area of ​​image B.

[0126] It should be noted that when the server sends only one image to the control end, the layer identifier of the image has no practical meaning.

[0127] Step 202: Determine a target image to be displayed according to the identification information.

[0128] For example, when the server receives an image sent by the acquisition end device, it generates identification information of the image and stores the image and the identification information in correspondence. When the server receives a display instruction, it parses the display instruction, obtains the identification information and display area information of at least one image to be displayed carried in the display instruction, and searches for the image corresponding to the identification information based on the identification information, thereby determining the target image to be displayed.

[0129] Step 203: Determine a target display image according to the display area information and the target image to be displayed.

[0130] For example, for each display area information, the position of the corresponding target image to be displayed on the display screen is determined, and then the target display image corresponding to each split screen is determined according to the position of the target image to be displayed on the display screen and the split screen position information of the display screen pre-stored in the server. The split screen position information is used to indicate the position of each split screen in the display screen.

[0131] Step 204: Send the target display image to a corresponding terminal device, so that the terminal device controls the split screen connected to the terminal device to display the target display image.

[0132] Optionally, the target display image is encoded to generate the target encoded data; and the target encoded data is sent to the corresponding terminal device.

[0133] For example, when determining the target display image, the server determines the split screen corresponding to the target display image according to the display area information, and then sends the target display image to the corresponding terminal device according to a pre-stored connection list, wherein the connection list includes a mapping relationship between the terminal device and the corresponding split screen, as shown in FIG2b, split screen 1 is connected to terminal device 1, split screen 2 is connected to terminal device 4, split screen 3 is connected to terminal device 2, split screen 4 is connected to terminal device 3, and terminal device 1, terminal device 2, terminal device 3 and terminal device 4 are all connected to the server. If the server determines that the target display image is the image displayed by split screen 2, the target display image is sent to terminal device 4.

[0134] The disclosed embodiment provides an image processing method. When receiving a display instruction, the server determines the target image to be displayed according to the identification information carried in the display instruction, and then determines the target display image according to the target image to be displayed and the display area information carried in the display instruction, and finally sends the target display image to the corresponding terminal device, so that each terminal device controls the corresponding split-screen display target display image. In this way, the server only needs to determine the target display image required by each terminal device, and the terminal device controls the corresponding split-screen display target display image. If the number of split screens is large, the server only needs to connect to multiple terminal devices. The number of split screens is not limited by the number of server slots. The server can support a large number of split screens, thereby making the server have a wider range of applications.

[0135] The present disclosure provides an image processing method, which is applied to a server, such as Figure 3a As shown, the data transmission method includes the following steps:

[0136] Step 301: Receive a display instruction.

[0137] The display instruction carries identification information and display area information of at least one image to be displayed; the display area information is used to indicate the position of the image to be displayed on the display screen; and the display screen includes at least two split screens.

[0138] Furthermore, the display instruction also carries at least one layer identifier of the image to be displayed; the layer identifier is coordinate information perpendicular to the plane of the display screen.

[0139] Step 302: Determine a target image to be displayed according to the identification information.

[0140] Step 303: Determine a display image of the display screen according to each display area information and the corresponding target image to be displayed.

[0141] For example, if there is a target image to be displayed, the display position of the target image to be displayed on the display screen is determined according to the display area information, and then the position on the display screen except the target image to be displayed is filled with a preset color or a preset picture, and finally the display image of the display screen is obtained.

[0142] Furthermore, the position of the corresponding target image to be displayed on the display screen is determined according to each display area information; the display level of the corresponding target image to be displayed is determined according to the layer identifier; and the display image of the display screen is determined according to the position of each target image to be displayed on the display screen and the corresponding display level.

[0143] For example, for multiple target images to be displayed, the server first determines the display position of the corresponding target image to be displayed on the display screen according to each display area information, that is, determines the display positions of the multiple target images to be displayed on the display screen respectively; then determines the display level of each target image to be displayed on the display screen according to the layer identifier corresponding to each target image to be displayed, and finally obtains the display image of the display screen according to the display level and the display position of the target image to be displayed on the display screen. Figure 2d As shown, if the target images to be displayed obtained by the server are image A and image B, the layer identifier of image A is 0, and the layer identifier of image B is 1, image A is placed in the middle right position of the display screen according to the display area information of image A, and image B is placed in the middle upper position of the display screen according to the display area information of image B; then, according to the layer identifier 0 of image A and the layer identifier 1 of image B, it is determined to display the part of image B in the overlapping part of image A and image B, so that the part of image B is displayed normally and the part of image A is covered, and the display image of the display screen finally obtained is shown in Figure 2d.

[0144] It should be noted that, in addition to the target image to be displayed, the positions on the display screen can also be filled with preset colors or preset pictures. Figure 2d Take filling with white as an example.

[0145] Step 304: segment the display image of the display screen according to the split-screen position information to obtain at least two split-screen images, and determine each of the split-screen images as the target display image.

[0146] For example, when determining the display image of the display screen, the server divides the display image of the display screen according to the split-screen position information. If the display screen includes four split screens, the display image of the display screen is divided into four split-screen images corresponding to the four split screens, and each split-screen image is the target display image; Figure 3bAs shown, the image corresponding to split screen 1 is split screen image 1, the image corresponding to split screen 2 is split screen image 2, the image corresponding to split screen 3 is split screen image 3, and the image corresponding to split screen 4 is split screen image 4. Split screen image 1, split screen image 2, split screen image 3 and split screen image 4 are all target display images.

[0147] Step 305: Generate the target coding data according to the target display image.

[0148] For example, when determining each target display image, the server encodes the target display image according to the split screen corresponding to the target display image, so that the generated target encoding data includes the target display image and the corresponding split screen identifier.

[0149] Step 306: Send the target coded data to the corresponding terminal device.

[0150] For example, when generating the target coded data, the server searches the connection list for the terminal device corresponding to the split screen identifier, and then sends the target coded data to the corresponding terminal device. Figure 3b The split screen image shown and Figure 2b Taking the schematic diagram shown as an example, split-screen image 1 is encoded and the encoded data is sent to terminal device 1; split-screen image 2 is encoded and the encoded data is sent to terminal device 4; split-screen image 3 is encoded and the encoded data is sent to terminal device 2; split-screen image 4 is encoded and the encoded data is sent to terminal device 3.

[0151] The disclosed embodiment provides an image processing method. When receiving a display instruction, the server determines the target image to be displayed according to the identification information carried in the display instruction, and then determines the display image of the display screen according to the display area information and the target image to be displayed carried in the display instruction, and divides the display image of the display screen according to the split-screen position information, and determines each split-screen image obtained by the division as the target display image, and finally sends the target display image to the corresponding terminal device, so that each split screen connected to the terminal device directly displays the target display image. In this way, the server only undertakes the task of dividing the display image of the display screen and the task of determining the split-screen image of each split screen, and the terminal device controls the connected split screen to directly display the target display image. If the number of split screens is large, the server only needs to connect to multiple terminal devices, and the number of split screens is not limited by the number of server slots. The server can support a large number of split screens, so that the application range of the server is wider.

[0152] The present disclosure provides an image processing method, which is applied to a server, such as Figure 4a As shown, the data transmission method includes the following steps:

[0153] Step 401: Receive a display instruction.

[0154] The display instruction carries identification information and display area information of at least one image to be displayed; the display area information is used to indicate the position of the image to be displayed on the display screen; and the display screen includes at least two split screens.

[0155] Furthermore, the display instruction also carries at least one layer identifier of the image to be displayed; the layer identifier is coordinate information perpendicular to the plane of the display screen.

[0156] Step 402: Determine a target image to be displayed according to the identification information.

[0157] Step 403: segment the target image to be displayed according to the display area information and the split-screen position information to obtain at least two original image sub-images; and determine each of the original image sub-images as the target display image.

[0158] The split screen position information is pre-stored and used to indicate the position of each split screen on the display screen.

[0159] For example, when the server determines the target image to be displayed, it needs to segment each target image to be displayed according to the display area information and the split screen position information, such as Figure 4b As shown, in Figure 4b In the display area filled with slashes, a part of image A is in split screen 2, and another part of image A is in split screen 4. The server divides image A into image A1 and image A2 according to the display area information and the split screen position information, wherein image A1 corresponds to split screen 2, and image A2 corresponds to split screen 4. Image A1 and image A2 are the two original image sub-images obtained.

[0160] like Figure 4c As shown, in Figure 4c , the image in the display area filled with slashes is image A, and the image displayed in the display area filled with dots is image B, wherein image A is acquired by acquisition end device 1, and image B is acquired by acquisition end device 2, a portion of image A is in split screen 2, another portion of image A is in split screen 4, a portion of image B is in split screen 1, and another portion of image B is in split screen 2. The server divides image A into image A1 and image A2 according to the display area information and split screen position information, wherein image A1 corresponds to split screen 2, and image A2 corresponds to split screen 4; and divides image B into image B1 and image B2, wherein image B1 corresponds to split screen 1, and image B2 corresponds to split screen 2, and image A1, image A2, image B1, and image B2 are the four original image sub-images obtained.

[0161] Step 404: Generate the target coded data according to the target display image.

[0162] For example, when determining each target display image, the server encodes the target display image according to the split screen corresponding to the target display image, so that the generated target encoding data includes the target display image and the corresponding split screen identifier.

[0163] Optionally, display sub-region information of the original image sub-image is determined; and the target coded data is generated according to the display sub-region information and the target display image.

[0164] For example, when determining each original image sub-image, the server determines the display sub-area information of the original image sub-image based on the display area information, and then encodes the original image sub-image based on the split screen corresponding to the original image sub-image, the display sub-area information and the original image sub-image, so that the generated target encoded data includes the original image sub-image, the corresponding split screen identifier and the display sub-area information.

[0165] Furthermore, the target coding data is generated according to the display sub-area information, the layer identifier and the target display image.

[0166] For example, when there are multiple target images to be displayed, in order to avoid overlapping of the target images to be displayed on the display screen, it is necessary to further encode according to the split screen corresponding to the original image sub-image, the display sub-area information, the corresponding layer identifier and the original image sub-image, so that the generated target encoding data includes the original image sub-image, the corresponding split screen identifier, the display sub-area information and the layer identifier.

[0167] Example, based on Figure 4b , encode image A1 and send the encoded data to terminal device 4; encode image A2 and send the encoded data to terminal device 3.

[0168] It should be noted that when there is only one target image to be displayed, the display instruction may carry a layer identifier or may not carry a layer identifier; when a layer identifier is carried, the layer identifier may be 0, which has no practical meaning.

[0169] Example, based on Figure 4c , encode image A1 and send the encoded data to terminal device 4; encode image A2 and send the encoded data to terminal device 3, and the encoded data of image A1 and image A2 both carry layer identifier 0; encode image B1 and send the encoded data to terminal device 1; encode image B2 and send the encoded data to terminal device 4, and the encoded data of image B1 and image B2 both carry layer identifier 1.

[0170] Step 405: Send the target coded data to the corresponding terminal device.

[0171] For example, when generating target coded data, the server searches for a terminal device corresponding to the split-screen identifier in a connection list, and then sends the target coded data to the corresponding terminal device.

[0172] The disclosed embodiment provides an image processing method. When a server receives a display instruction, it determines a target image to be displayed according to identification information carried in the display instruction, and then segments the target image to be displayed according to split-screen position information and display area information carried in the display instruction, and determines each original image sub-image obtained by segmentation as a target display image, and finally sends the target display image to a corresponding terminal device, so that each terminal device displays the received original image sub-image on the connected split screen according to the corresponding display sub-area information. In this way, the server only undertakes the task of displaying the image of the split display screen, and the terminal device controls the connected split screen to display the original image sub-image according to the display sub-area information, thereby reducing the workload of the server; in addition, if the number of split screens is large, the server only needs to connect to multiple terminal devices, and the number of split screens is not limited by the number of server card slots. The server can support a large number of split screens, so that the application range of the server is wide.

[0173] The embodiment of the present disclosure provides an image processing method, which is applied to terminal devices, wherein each terminal device is connected to a server, and each terminal device is connected to a split screen of a display screen, such as Figure 5 As shown, the data transmission method includes the following steps:

[0174] Step 501: Receive a target display image.

[0175] Optionally, receive target encoded data.

[0176] The target coded data is data generated according to the target display image.

[0177] Step 502: Control the split screen connected to the terminal device to display the target display image.

[0178] Optionally, when the target display image is a split-screen image, upon receiving the target coded data, the terminal device decodes the target coded data, obtains the split-screen image, and displays the split-screen image directly on the connected split screen.

[0179] For example, terminal device 1 decodes the acquired coded data to obtain split-screen image 1, and displays split-screen image 1 directly on split-screen 1; terminal device 4 decodes the acquired coded data to obtain split-screen image 2, and displays split-screen image 2 directly on split-screen 2; terminal device 2 decodes the acquired coded data to obtain split-screen image 3, and displays split-screen image 3 directly on split-screen 3; terminal device 3 decodes the acquired coded data to obtain split-screen image 4, and displays split-screen image 4 directly on split-screen 4. In this way, the images displayed on split-screen 1, split-screen 2, split-screen 3, and split-screen 4 form the following. Figure 3b The display image shown is shown.

[0180] Optionally, when the target display image is an original image sub-image, the target coded data includes display sub-region information, and the original image sub-image is displayed on a split screen connected to the terminal device according to the display sub-region information.

[0181] For example, when the target display image is an original image sub-image, the terminal device obtains the display sub-area information corresponding to the original image sub-image from the target encoded data, determines the display position of the original image sub-image on the split screen according to the display sub-area information, and then displays the original image sub-image at that position.

[0182] Furthermore, the target coding data also includes a layer identifier, and the original image sub-image is displayed on a split screen connected to the terminal device according to the layer identifier and the display sub-area information.

[0183] The layer identifier is coordinate information perpendicular to the plane of the display screen.

[0184] For example, when there are multiple target display images, and the target display image is a sub-image of the original image, the target encoding data also needs to carry a layer identifier, and the display level of the original image sub-image on the split screen is determined according to the layer identifier, and the display position of the original image sub-image on the split screen is determined according to the display sub-area information, so that the original image sub-image is displayed at the corresponding position of the split screen according to the display level and display position.

[0185] based on Figure 4b , terminal device 4 decodes the acquired target coded data to obtain image A1 and layer identifier 0, and displays image A1 at the corresponding position of split screen 2; terminal device 3 decodes the acquired target coded data to obtain image A2 and layer identifier 0, and displays image A2 at the corresponding position of split screen 4. In this way, image A1 and image A2 form image A, which meets user needs.

[0186] based on Figure 4c, terminal device 4 decodes the acquired target coded data to obtain image A1 and layer identifier 0, and displays image A1 at the corresponding position of split screen 2; terminal device 3 decodes the acquired target coded data to obtain image A2 and layer identifier 0, and displays image A2 at the corresponding position of split screen 4, so that image A1 and image A2 constitute image A; in addition, terminal device 4 also acquires the target coded data for image B, decodes the target coded data for image B, obtains image B2 and layer identifier 1, and displays image B2 on split screen 2; terminal device 1 decodes the acquired target coded data to obtain image B1 and layer identifier 1, and displays image B1 on split screen 1, so that image B1 and image B2 constitute image B, which meets user needs.

[0187] It should be noted that image A1 and image B2 are displayed simultaneously on split screen 2, and there is an overlapping portion between image A1 and image B2. Since the layer identifier 0 corresponding to image A1 is smaller than the layer identifier corresponding to image B2, image B2 is displayed in the overlapping portion.

[0188] It should be noted that, when there is a target display image, the target coding data may also carry a layer identifier, which may be 0 and has no practical meaning.

[0189] The disclosed embodiment provides an image processing method. When receiving a display instruction, the server determines the target image to be displayed according to the identification information carried in the display instruction, and then determines the target display image according to the target image to be displayed and the display area information carried in the display instruction, and finally sends the target display image to the corresponding terminal device, so that each terminal device controls the corresponding split-screen display target display image. In this way, the server only needs to determine the target display image required by each terminal device, and the terminal device controls the corresponding split-screen display target display image. If the number of split screens is large, the server only needs to connect to multiple terminal devices. The number of split screens is not limited by the number of server slots. The server can support a large number of split screens, thereby making the server have a wider range of applications.

[0190] The present disclosure provides an image processing method, which is applied to a server and a terminal device. As shown in FIG6 , the data transmission method includes the following steps:

[0191] Step 601: The server receives a display instruction.

[0192] The display instruction carries identification information and display area information of at least one image to be displayed; the display area information is used to indicate the position of the image to be displayed on the display screen; and the display screen includes at least two split screens.

[0193] Step 602: The server determines a target image to be displayed according to the identification information.

[0194] Step 603: The server determines a target display image according to the display area information and the target image to be displayed.

[0195] Step 604: The server sends the target display image to the corresponding terminal device.

[0196] Step 605: The terminal device controls the split screen connected to the terminal device to display the target display image.
