Detailed Description
The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
Generally, 1 high-resolution workstation with a plurality of display cards is used for splicing a display desktop on a large screen, and high-resolution industrial control software (configuration) is run on the desktop, and the usage of the scheduling centers of subways and power grids is common. However, the industrial control software is generally built in several periods and may come from different developers, and for maintenance convenience, the industrial control software is respectively deployed on own hardware, and the resolution of one set of large screen can only meet the application of one developer, and when the industrial control software is developed by different developers, the large screen cannot be displayed according to a uniform resolution, so that a high-resolution workstation needs to spend more resources for adjustment, which not only reduces the display speed of a large-screen image, but also consumes too much resources.
Based on this, the following technical solutions are proposed in the present application, specifically see the following:
in one embodiment, as shown in fig. 1, fig. 1 is an application architecture diagram of an ultra-high resolution image display system according to an embodiment of the present application; the present application provides a super high resolution image display system, which may include: at least one transmitting terminal 110, and a receiving terminal 130, wherein the resolution of a first display device 120 connected to the transmitting terminal 110 is lower than the resolution of a second display device 140 connected to the receiving terminal 130.
The sending terminal 110 is configured to create a memory DC according to the resolution of the second display device 140 after acquiring the original image, draw a target image corresponding to the original image in the memory DC, create a corresponding structural body according to the memory DC and the target image, and send the structural body to the receiving terminal 130.
The receiving terminal 130 is configured to receive the structural body, create a window DC according to the structural body, draw a target image in the structural body 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, and the receiving terminal 130 may be connected to the second display device 140, and in order to obtain a high-resolution display picture and save the number of computer hardware devices, this application may only configure the second display device 140 connected to the receiving terminal 130 as a display device with ultrahigh resolution, for example, the resolution of an image 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 sending 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, and the like, which is used for generating a high-score display screen; the receiving terminal 130 in the present application may be used as a high-resolution workstation, the second display device 140 connected to the receiving terminal 130 may be used as a high-resolution display connected to the high-resolution workstation, and the receiving terminal 130 and the sending terminal 110 are connected through a network, where 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 sending terminal 110, and create the 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 for storing the capability of a specific device and the related attributes of how to draw some items on the device. Generally, the DC may include a screen DC and a memory DC, wherein the screen DC is directly associated with a screen, and the content 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 associated with the screen DC, and the memory DC is operated first, and then the memory DC is completely copied to the screen DC, 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 present 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 portions, a corresponding memory DC is created for each portion of the original image, and the portion of the original image is drawn by using the memory DC; in addition, when the memory DC is created, the memory window name and the memory window ID of the memory DC may be defined, and each memory DC has its unique memory window name and memory window ID, so as to distinguish between the memory DC and other memory DCs, and facilitate the receiving terminal 130 to 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 be +1 behind the memory window name, for example, the memory window name in the ScreenData (structure) of the memory window 1 is "circuit diagram", the memory window name in the ScreenData of the memory window 2 is "circuit diagram 1", and so on.
Furthermore, after the original image is drawn in the memory DC and the target image is obtained, the sending terminal 110 may call the application installed therein to create the structural body, and the structural body needs to be created according to the memory DC and the target image in the creation process, and after the corresponding structural body is created, the structural body may be sent to the receiving terminal 130, so that the receiving terminal 130 draws the target image according to the structural body and displays the target image through the second display device 140.
Here, the structure in the present application refers to a data set composed of a series of data having the same type or different types. In C language, a structure refers to a data structure, which is a type of aggregate data type in C language. The structure may be declared as a variable, pointer, array, or the like, to implement more complex data structures. The structure is also a collection of elements called members of the structure, and the members can be of different types, and the members are generally accessed by name.
The elements in the structure 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, an image code, an image byte number, a data buffer, etc. related to the target image, a local IP of the sending terminal 110, a timestamp, a text check code, etc. of the structure, which may be configured according to actual situations.
It is understood that the image coding herein refers to coded data obtained by coding a target image; the number of image bytes 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 file, the first section is a small section of verification code, the second section only contains complete verification code and data, and the data is continuously received when the verification codes are compared to be the same, so that the security of data transmission is ensured; the time stamp here can be accurate to thousandth of a second, and images with the same time stamp can be regarded as the same image.
When the receiving terminal 130 receives the structural body transmitted by the transmitting terminal 110, a window DC may be created according to the structural body, and the window DC is used to draw a target image in the structural body, and then the drawn target image is transmitted to the second display device 140 for display, so as to achieve a uniform display of high-resolution display images.
It should be noted that, the window DC herein refers to the screen DC in the foregoing, 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 can be directly transmitted to the second display device 140 for display.
In drawing a target image in a structural body using the window DC, the target image may be first created from a data buffer in the structural body and then drawn in the window DC. The globalock function may be called to create the target image according to the process of creating the target image in the data cache region in the structure, after the globalock function is called, the memory block may be locked, the function may accept a memory handle as a parameter, and then a pointer pointing to the locked memory block is returned, and the receiving terminal 130 may read and write the memory using the pointer, thereby creating the target image.
In the above embodiment, when the sending 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 is drawn in the memory DC, then a corresponding structural body may be created according to the memory DC and the target image, and the structural body is sent to the receiving terminal 130, and after the receiving terminal 130 receives the structural body, a corresponding window DC may be created according to the structural body, and the window DC is used to draw the target image in the structural body, and the target image is transmitted to the second display device 140 for display; in the 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 a Windows desktop and a display driving technology, the resolution can break through the 16K limitation, and the sending terminal can directly access the memory to code and send the target image through a network without copying the target image from the display memory to the memory, so that the display performance is more efficient, and more resources are not required to be spent by high-resolution workstations to adjust.
In an 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 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.
In this embodiment, after the sending terminal 110 creates the memory DC, a compatible bitmap may be created in the memory, and the compatible bitmap is associated with the memory DC, so that after the sending terminal 110 draws a target image corresponding to an original image in the memory DC, the format of the target image is converted into the format of the compatible bitmap.
It can be understood that, in general, the initialization environment of the DC created by the same kind of device is the same, but the device generally adjusts the attribute during the operation process, and at this time, the DC created by another kind of device is not compatible because the initial attribute is different. Therefore, the memory DC in the present application may be a compatible DC created based on a DC at a certain operating time, and the compatible DC may copy the DC attribute at the current time, thereby effectively ensuring the compatibility thereof.
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 correspondingly created, otherwise any drawing operation is invalid. The compatible bitmap is a memory picture format and is stored in a memory, and after the compatible bitmap is created, the API function can be used for establishing a relation with a memory DC.
And when the compatible bitmap is linked with the memory DC, the format of the target image drawn in the memory DC can be converted into the format of the compatible bitmap.
In an embodiment, the sending terminal 110 may be further configured to create a data buffer area in the memory, and write the format-converted target image into the data buffer area.
In this embodiment, after the sending terminal 110 converts the format of the target image into the format compatible with the bitmap, the sending terminal 110 may further create a data buffer area in the memory, and write the format-converted target image into the data buffer area, so as to not only facilitate the judgment of the correctness of the format-converted target image, but also facilitate the image transmission of the format-converted target image.
In an 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 format-converted target image stored in the data cache region through the image detection module and verify the correctness of the format-converted target image.
In this embodiment, it is assumed that the Windows of the image detection module are 1920 wide and 1080 high, the coordinates of the upper left corner of the initial picture are (0, 0), and the Windows of the image detection module are 1920 wide and 1080 high, respectively, so that 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 disclosure; the sending terminal 110 may be further configured to encode and compress the structure to obtain a data packet, and send the data packet to the receiving terminal 130; after receiving the data packet, the receiving terminal 130 analyzes the data packet to obtain the structural body in the data packet.
In this embodiment, as shown in fig. 2, a computer a in fig. 2 refers to a sending terminal 110 in this application, a display device C refers to a first display device 120 connected to the sending terminal 110 in this application, a computer B refers to a receiving terminal 130 in this application, and a display device D refers to a second display device 140 connected to the receiving terminal 130 in this application.
As can be seen from fig. 2, after a memory image, that is, a target image compatible with a bitmap format, is generated by the computer a, a corresponding structure may be created according to the target image and the memory DC, and the structure is subjected to secondary encoding and compression to form a data packet, and then the data packet is sent to the computer B, and the computer B analyzes the data packet to obtain the structure in the data packet, draws a window through the structure, and finally displays the drawn target image on the display device D.
Further, since the structure includes the target image, and the format of the target image is a format compatible with the bitmap, a BMCP bitmap compression algorithm may be used when compressing the structure, and may be specifically set according to an actual situation, which is not limited herein.
The data packet formed by secondarily encoding the structure according to the present application can compress byte data in the structure, so that the structure can be 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 an agreed decompression and decoding manner, so as to restore the data packet to the structure.
In one embodiment, the receiving terminal 130 may be further configured to determine whether to create the window DC according to the timestamp in the structural body.
In this embodiment, the structural body may include a timestamp, and the receiving terminal 130 may determine the correctness and timeliness of data in the current structural body by using the timestamp, so as to determine whether to create the window DC.
Specifically, after the receiving terminal 130 receives the structural body, the timestamp in the currently received structural body may be compared with the timestamp in the previously received structural body, and if the current timestamp is smaller than the previous timestamp, it indicates that the content in the structural body is older, at this time, the structural body may be discarded and the memory may be released, and if the current timestamp is larger than the previous timestamp, the next image rendering 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 may be acquired, the structure corresponding to the local IP stored in the memory may be acquired, and then the timestamp in the currently received structure may be compared with the timestamp in the structure stored in the memory, so that the comparison result may be acquired quickly.
In one embodiment, when there are a plurality of sending terminals 110 and target images in the plurality of sending terminals 110 need to be displayed simultaneously, the process of the receiving terminal 130 creating the window DC according to the structural body may include:
the receiving terminal 130 creates different window DCs according to the structural body sent by the sending terminal 110 with different addresses, and respectively controls the starting positions and the window sizes of the different window DCs.
In this embodiment, when a plurality of sending terminals 110 send a structure to a receiving terminal 130 and declare that a target image in the structure needs to be displayed simultaneously, the receiving terminal 130 may create different window DCs according to the structures sent by sending terminals 110 with different addresses and call an external program to control the starting position and size of the window DC.
For example, the present application may set the window DC as a window of an application program in the receiving terminal 130, the window size is consistent with the size of the target image in the structure transmitted in the transmitting terminal 110, the window itself may drag the frame to change the window size, and the target image may also be selected to be displayed in a stretched or centered manner according to actual needs.
In an embodiment, when a plurality of target images in one of the transmitting terminals 110 need to be displayed simultaneously, the process of the receiving terminal 130 creating the window DC according to the structural body may include:
the receiving terminal 130 creates different window DCs according to each structural body transmitted by the transmitting terminal 110, and controls the starting positions and the window sizes of the different window DCs, respectively.
In this embodiment, when one sending terminal 110 sends a plurality of structural bodies to the receiving terminal 130 and states that the target images in the plurality of structural bodies need to be displayed simultaneously, for example, when the sending terminal 110 divides a certain original image into a plurality of parts for drawing, it may state that the target images in the plurality of parts need to be displayed simultaneously to the receiving terminal 130, so as to form a complete target image.
At this time, the receiving terminal 130 may create different windows DC according to the memory window name, the memory window ID, the window height, and the window width in each structural body sent by the sending terminal 110, and use an external program to respectively control the start positions and the window sizes of the different windows DC, thereby obtaining a complete target image.
In an embodiment, as shown in fig. 3, fig. 3 is a schematic flowchart of a super high resolution image display method according to an embodiment of the present application; the present application also provides an ultra-high resolution image display method, which is applied to an ultra-high resolution image display system, the system including at least one transmitting terminal 110, and one receiving terminal 130, a resolution of a first display device 120 connected to the transmitting terminal 110 is lower than a resolution of a second display device 140 connected to the receiving terminal 130, the method may include:
s110: the transmitting terminal 110 acquires an original image.
