Detailed Description
The following description of the embodiments of the present application will be made clearly and fully with reference to the accompanying drawings, in which it is evident that the embodiments described are only some, but not all, of the embodiments of the present application. All other embodiments, which can be made by one of ordinary skill in the art without undue burden from the present disclosure, are within the scope of the present disclosure.
In general, a large screen will use 1 high-resolution workstation with multiple graphics cards to splice and display a desktop, and high-resolution industrial control software (configuration) is run on the desktop, which is more common in use such as a subway, a dispatching center of a power grid, and the like. However, these industrial control software are generally built in several periods and may come from different developers, and for convenience of maintenance, these industrial control software are deployed on the home hardware respectively, and the resolution of a set of large screen can only meet the application of one developer, when the industrial control software is developed by different developers, the large screen cannot be displayed according to the uniform resolution, so that the high-resolution workstation needs to spend more resources for adjustment, which not only results in a reduction of the display speed of the large screen image, but also consumes too much resources.
Based on this, the following technical solutions are proposed in the present application, see specifically below:
in one embodiment, as shown in fig. 1, fig. 1 is an application architecture diagram of an ultrahigh resolution image display system provided in an embodiment of the present application; the present application provides an ultra-high resolution image display system, which may include: at least one transmitting terminal 110, and one receiving terminal 130, the resolution of a first display device 120 to which the transmitting terminal 110 is connected is lower than the resolution of a second display device 140 to which the receiving terminal 130 is connected.
The transmitting terminal 110 is configured to, after acquiring an original image, create a memory DC according to the resolution of the second display device 140, draw a target image corresponding to the original image in the memory DC, create a corresponding structure according to the memory DC and the target image, and then transmit the structure to the receiving terminal 130.
The receiving terminal 130 is configured to receive the structure, create a window DC according to the structure, draw a target image in the structure using the window DC, and transmit the target image to the second display device 140 for display.
In this embodiment, the image display system may include a plurality of sending terminals 110 and one receiving terminal 130, where the sending terminal 110 in this application may be connected to the first display device 120, the receiving terminal 130 may be connected to the second display device 140, and in order to save the number of computer hardware devices while obtaining a high-resolution display screen, in this application, only the second display device 140 connected to the receiving terminal 130 may be configured as a display device with ultra-high resolution, for example, the image resolution is greater than 8K, that is 7680×4320, so that the resolution of the first display device 120 connected to the sending terminal 110 is lower than the resolution of the second display device 140 connected to the receiving terminal 130, thereby implementing resource optimization configuration.
It is understood that the transmitting terminal 110 in the present application may be any computer device, such as at least one of a desktop computer, a portable computer, a laptop computer, a tablet computer, etc., which is used to generate a high-resolution display screen; the receiving terminal 130 in the present application may be used as a high-definition workstation, and the second display device 140 connected to the receiving terminal 130 may be used as a high-definition display connected to the high-definition workstation, where the receiving terminal 130 and the transmitting terminal 110 are connected through a network, and the network includes, but is not limited to, a wide area network, a metropolitan area network, or a local area network.
After the application architecture diagram of the present application is constructed, the present application may acquire an original image through the transmitting terminal 110 and create a memory DC according to the resolution of the second display device 140 so as to draw a target image corresponding to the original image in the memory DC.
It should be noted that DC (DeviceContext) is an example of a structure of GDI, which is used to store capabilities of a specific device and how relevant properties of some items are drawn on the device. In general, the DC may include a screen DC and a memory DC, wherein the screen DC is directly associated with a screen, and contents drawn on the screen may be changed by operating the screen DC through a graphic device interface; the memory DC has the same context as the screen DC, but is not directly related to the screen, but the memory DC is operated first, and then the memory DC is copied to the screen DC entirely, so that the display content of the display is changed, which is a so-called double-buffer technology, and screen flicker can be reduced to a certain extent.
Further, if the size of the original image in the application is too large and the original image cannot be drawn in the same memory DC, the original image may be divided into a plurality of parts, and a corresponding memory DC is created for each part of the original image, and the part of the original image is drawn by using the memory DC; in addition, when the memory DCs are created, the memory window names and the memory window IDs of the memory DCs can be defined, and each memory DC has a unique memory window name and a unique memory window ID so as to distinguish between the memory DCs and other memory DCs, and the receiving terminal 130 can conveniently splice the target image according to different memory window names and memory window IDs.
When the application program in the sending terminal 110 of the present application encounters the same memory window name, it will automatically follow the memory window name by +1, for example, the memory window name in the screen data (structure body) of the memory window 1 is "line map", the memory window name in the screen data of the memory window 2 is "line map 1", and so on.
Further, after the original image is drawn in the memory DC and the target image is obtained, the transmitting terminal 110 may call the installed application program to create a structure, the structure needs to be created according to the memory DC and the target image in the creation process, and after the corresponding structure is created, the structure may be sent to the receiving terminal 130, so that the receiving terminal 130 draws the target image according to the structure and displays the target image through the second display device 140.
Wherein a structure in the present application refers to a data set consisting of a series of data of the same type or different types. In the C language, a structure refers to a data structure, which is a class of aggregate data types in the C language. The structure may be declared as a variable, pointer, array, or the like, to implement a more complex data structure. A structure is also a collection of elements that are referred to as members of the structure, and these members may be of different types, members typically being accessed by name.
The elements in the structure body of the present application may include a memory window name, a memory window ID, a window width, a window height, etc. related to the memory DC, or may also include an image code, an image byte number, a data buffer area, etc. related to the target image, or may also include a local IP of the sending terminal 110, where a timestamp, a text check code, etc. of the structure body may be specifically configured according to practical situations.
It is to be understood that, the image encoding herein refers to encoded data obtained by encoding a target image; the number of bytes of the image refers to the number of bytes corresponding to the encoded image; the data buffer area refers to a storage area of the target image; the file check code is set because the receiving terminal 130 generally sends two sections of codes when receiving, the first section is a small section of check code, the second section contains complete check code and data, and the data is continuously received when the comparison check codes are the same, so that the safety of data transmission is ensured; while the time stamp here may be accurate to one thousandth of a second, having the same time stamp may be considered the same image.
When the receiving terminal 130 receives the structure body transmitted by the transmitting terminal 110, a window DC may be created according to the structure body, and the window DC may be used to draw a target image in the structure body, and then the drawn target image may be transmitted to the second display device 140 for display, so as to realize unified display of the high-resolution display image.
It should be noted that, the window DC refers to the screen DC, and since the data displayed by the window is directly used for data interaction with the display device, the target image drawn in the window DC in the present application may be directly transmitted to the second display device 140 for display.
In drawing a target image in a structure using the window DC, the target image may be first created from a data buffer in the structure, and then drawn in the window DC. According to the process of creating the target image in the data buffer area in the structure body, the GlobalLock function can be called to create, after the GlobalLock function is called, the memory block can be locked, the function can accept a memory handle as a parameter, then a pointer pointing to the locked memory block is returned, and the receiving terminal 130 can use the pointer to read and write the memory, so that the target image is created.
In the above embodiment, when the transmitting terminal 110 generates the target image, the memory DC may be created according to the resolution of the second display device 140 connected to the receiving terminal 130, and the target image may be drawn in the memory DC, then a corresponding structure may be created according to the memory DC and the target image, and the structure may be transmitted to the receiving terminal 130, and when the receiving terminal 130 receives the structure, a corresponding window DC may be created according to the structure, and the target image in the structure may be drawn using the window DC, and the target image may be transmitted to the second display device 140 for display; in the present application, the sending terminal 110 draws the target image through the memory DC, and the memory DC is created according to the resolution of the second display device 140 connected to the receiving terminal 130, so that the sending terminal is not limited by the Windows desktop and the display driving technology, the resolution can break through the 16K limitation, and the sending terminal can directly access the memory without copying the target image from the video memory to the memory, and the code can be sent through the network, so that the display performance is more efficient, and the high-resolution workstation does not need to spend more resources for adjustment.
In one embodiment, the sending terminal 110 may be further configured to create a compatible bitmap in a memory, and associate the compatible bitmap with the memory DC; after drawing a target image corresponding to the original image in the memory DC, the transmitting terminal 110 converts the format of the target image into the format of the compatible bitmap.
In this embodiment, after the sending terminal 110 creates the memory DC, a compatible bitmap may also be created in the memory, and the compatible bitmap is associated with the memory DC, so that after the sending terminal 110 draws the target image corresponding to the original image in the memory DC, the format of the target image is converted into the format of the compatible bitmap.
It will be appreciated that the initialization environment for the DC created by the same class of devices is typically the same, but the devices will typically adjust the attributes during operation, at which point the DC of one class of devices is created again, with a high likelihood of incompatibility due to the different initial attributes. Therefore, the memory DC in the method can be a compatible DC which is created by taking the DC at a certain running time as a reference, and the compatible DC can replicate the DC attribute at the current time, so that the compatibility of the compatible DC is effectively ensured.
However, since the compatible DC does not contain a bitmap by default, and any operation of the DC itself is operated on the bitmap, after the compatible DC is created, a compatible bitmap must be created accordingly, otherwise any drawing operation is ineffective. The compatible bitmap in the application is a memory picture format, and is stored in a memory, and after the compatible bitmap is created, an API function and a memory DC can be used for establishing a connection.
After the association between the compatible bitmap and the memory DC is established, the format of the target image drawn in the memory DC can be converted into the format of the compatible bitmap.
In one embodiment, the sending terminal 110 may be further configured to create a data buffer in the memory, and write the target image after format conversion into the data buffer.
In this embodiment, after the sending terminal 110 converts the format of the target image into the format of the compatible bitmap, the sending terminal 110 may also create a data buffer area in the memory, and write the target image after the format conversion into the data buffer area, so that it is convenient to determine the correctness of the target image after the format conversion, and also facilitate image transmission of the target image after the format conversion.
In one embodiment, the sending terminal 110 may be further configured to traverse the format-converted target image stored in the data buffer, and verify the correctness of the format-converted target image.
In this embodiment, when the user needs to verify the correctness of the image, a detection instruction may be issued to the sending terminal 110, and the sending terminal 110 may traverse the target image after format conversion stored in the data buffer area through the image detection module, and verify the correctness of the target image after format conversion.
The image detection module corresponds to a Windows window, the window size of which is smaller than the maximum resolution of the current display device, in this embodiment, it is assumed that the window width of the image detection module is 1920, the height is 1080, the left upper corner coordinate of the initial picture is (0, 0), the right lower corner is the window width and the height of the image detection module (1920, 1080), and the image detection module can freely control the display area.
In one embodiment, as shown in fig. 2, fig. 2 is a schematic diagram of a data transmission structure between a computer a and a computer B according to an embodiment of the present application; the transmitting terminal 110 may be further configured to encode and compress the structure to obtain a data packet, and transmit the data packet to the receiving terminal 130; after receiving the data packet, the receiving terminal 130 analyzes the data packet to obtain a structure body in the data packet.
In this embodiment, as shown in fig. 2, a computer a in fig. 2 refers to a transmitting terminal 110 in the present application, a display device C refers to a first display device 120 connected to the transmitting terminal 110 in the present application, a computer B refers to a receiving terminal 130 in the present application, and a display device D refers to a second display device 140 connected to the receiving terminal 130 in the present application.
As can be seen from fig. 2, when a memory image, i.e., a target image compatible with a bitmap format, is generated by the computer a, a corresponding structure can be created according to the target image and the memory DC, the structure is secondarily encoded and compressed to form a data packet, the data packet is then sent to the computer B, the computer B analyzes the data packet to obtain the structure in the data packet, and a window is drawn through the structure, and finally the drawn target image is displayed on the display device D.
Further, since the structure includes the target image, the format of the target image is a bitmap compatible format, the BMCP bitmap compression algorithm may be used when compressing the structure, and the configuration may be specifically set according to the actual situation, which is not limited herein.
The data packet formed after the secondary encoding is performed on the structural body can compress byte data in the structural body, so that the structural body is conveniently transmitted to the receiving terminal 130, and after the receiving terminal 130 receives the data packet, the data packet can be decompressed and decoded according to a contracted decompression and decoding mode, so that the structural body is restored.
In one embodiment, the receiving terminal 130 may also be configured to determine whether to create a window DC based on the time stamp in the fabric.
In this embodiment, the structure may include a time stamp, and the receiving terminal 130 may determine whether to create the window DC by using the time stamp to determine the correctness and timeliness of the data in the current structure.
Specifically, when the receiving terminal 130 receives the structure, the timestamp in the currently received structure may be compared with the timestamp in the previously received structure, if the current timestamp is smaller than the previous timestamp, it indicates that the content in the structure is older, at this time, the structure may be discarded and the memory may be released, and if the current timestamp is larger than the previous timestamp, the next image drawing may be performed.
Further, when comparing the timestamp in the currently received structure with the timestamp in the previously received structure, the local IP in the currently received structure can be obtained, then the structure corresponding to the local IP stored in the memory is obtained, and then the timestamp in the currently received structure is compared with the timestamp in the structure stored in the memory, so that the comparison result can be obtained quickly.
In one embodiment, when the transmitting terminal 110 is plural and the target images in the plural transmitting terminals 110 need to be displayed at the same time, the process of creating the window DC by the receiving terminal 130 according to the structure may include:
the receiving terminal 130 creates different window DCs according to the structures transmitted by the transmitting terminals 110 of different addresses, and controls the starting positions and window sizes of the different window DCs, respectively.
In this embodiment, when a plurality of transmitting terminals 110 transmit a structure to a receiving terminal 130 and declare that a target image in the structure needs to be displayed at the same time, the receiving terminal 130 may create different window DCs according to the structures transmitted by the transmitting terminals 110 of different addresses and call an external program to control the start position and size of the window DC.
For example, the present application may set the window DC to a window of a certain application program in the receiving terminal 130, where the window size is consistent with the size of the target image in the structure body sent in the sending terminal 110, and the window itself may drag the frame to change the window size, and the target image may also select whether to be stretch-matched or centrally displayed according to actual needs.
In one embodiment, when a plurality of target images in one of the transmitting terminals 110 need to be displayed at the same time, the process of creating the window DC by the receiving terminal 130 according to the structure may include:
the receiving terminal 130 creates different window DCs according to the respective structures transmitted from the transmitting terminal 110, and controls the starting positions and window sizes of the different window DCs, respectively.
In this embodiment, when one transmitting terminal 110 transmits a plurality of structures to the receiving terminal 130 and declares that the target images in the plurality of structures need to be displayed simultaneously, for example, the transmitting terminal 110 divides a certain original image into a plurality of parts to draw, the receiving terminal 130 may declare that the target images of the plurality of parts need to be displayed simultaneously, thereby forming a complete target image.
At this time, the receiving terminal 130 may create different windows DC according to the memory window names, the memory window IDs, the window heights, and the window widths in the respective structures transmitted from the transmitting terminal 110, and control the starting positions and the window sizes of the different windows DC by using external programs, respectively, so as to obtain a complete target image.
