In practical applications, other devices, such as a mobile terminal or a network device, may be further included in the virtual shooting system according to needs, which is not limited in this embodiment.

Optionally, each host computer 011 may be connected to one or more rendering devices 021, and a specific connection manner may be selected according to actual requirements and compatibility of the devices. As an example, a connection such as wired or wireless may be made through a local area network or the internet, and communication may be made using a network transmission protocol. As an example, the main control machine may transmit various control instructions to the rendering device connected thereto, for example, may be a control instruction containing specific image information, or the like.

Optionally, each rendering device 021 may be connected to one or more broadcast control processing devices 031; the specific connection mode can be selected according to the actual requirements and the compatibility of the equipment. As an example, a DP (DisplayPort, a digital display interface standard) connection may be included, which may be used to transmit high quality audio and video signals. Or HDMI (High-Definition Multimedia Interface, a High-definition digital audio-video interface standard), which can combine audio, video and control signals for transmission over one cable. As an example, the rendering device 021 may send various control instructions to a broadcast control processing device connected thereto, for example, the rendering device may serve as an image signal source, send a control instruction containing a rendering image, and the like.

In practice, the play control processing device 031 is optional, and may not be configured in some scenarios. Optionally, each of the broadcast control processing devices 031 may be connected to one or more display screens 040; the specific connection mode can be selected according to the actual requirements and the compatibility of the equipment. As examples, DP or HDMI connections may also be included, USB (Universal Serial Bus ) or network connections, etc. The broadcast control processing device may be used to control and manage a display screen connected thereto, as an example, the broadcast control processing device 031 may be used for data transmission and decoding, e.g., the broadcast control processing device 031 may receive a signal from an external source (e.g., an on-screen machine, a computer, a mobile terminal or a media player, etc.) and decode it into a format suitable for display on the display screen; the method can also be used for display control, such as overall control and scheduling of a display screen, including brightness adjustment, color correction, gray scale control and the like; the method can be used for carrying out partition management on the display screen, the display screen can be divided into a plurality of independent areas, and each area can display different contents.

The virtual shooting needs to use the display screen to render the background picture, and the acquired color obtained by shooting the display screen by the shooting equipment is inconsistent with the rendered color received by the display screen, so that certain distortion exists between the rendered color displayed by the display screen and the acquired color obtained by shooting the shooting equipment, and therefore, each display screen and the camera on the virtual shooting site need to be subjected to color calibration, and the acquired color acquired by the camera is ensured to be consistent with the rendered color received by the LED screen. The color calibration process is that the original colors are displayed on a display screen, then the colors acquired through the shooting equipment are acquired, and the corresponding relation between the original colors and the acquired colors is found out. This process requires a plurality of software and hardware processes, such as a rendering device, a play control processing device, and a photographing device shown in fig. 1, and the like; each link device converts the input color according to the understanding of the system and transmits the color to the next link, so that each link needs to have correct configuration to ensure that the display screen receives the correct color value, and the shooting device accurately acquires the color value. If one or more of the links is not properly configured, the color calibration effect may be affected or even erroneous.

In the related art, after a user determines a color gamut of color calibration, the user manually inputs a graphics card configuration of a rendering device, a play control configuration of a play control processing device, and then debugs parameters of a photographing device. The scheme is low in efficiency and easy to make mistakes in manual configuration, a plurality of rendering devices, a broadcast control processor and shooting devices can exist on a shooting site, the whole configuration process needs to consume large manpower, errors are easy to configure, and color calibration accuracy is easy to be reduced after the errors are configured, or color calibration fails.

The master control terminal of the embodiment maintains multiple copies of standard configuration data corresponding to different color gamuts, where the standard configuration data may include standard video card configuration information and standard broadcast control configuration information. For example, the master may maintain: standard configuration data of color gamut 1 (standard video card configuration information 1+standard play control configuration information 1), standard configuration data of color gamut 2 (standard video card configuration information 2+standard play control configuration information 2), standard configuration data of color gamut 3 (standard video card configuration information 3+standard play control configuration information 3), and the like.

Optionally, the main control computer can be connected with different rendering devices, and different manufacturers or types of graphics cards can be configured in different rendering devices, so that standard graphics card configuration information under the same color gamut can be further refined based on the types of different graphics cards.

The method for obtaining the type of the broadcast control processing device can be various, for example, a configuration interface can be provided for a user, and the type of the broadcast control processing device submitted by the user can be obtained through the configuration interface; or the master control end can be obtained through interaction with a program running on the broadcast control processing device, which is not limited in this embodiment.

As an example, the standard configuration data of the different color gamuts maintained by the master may also be:

and so on.

In practical applications, the graphics card configuration information may include one or more of the following combinations:

(1) desktop color depth: the number of colors displayed by the display screen is indicated, typically in bits. For example, a 24 bit color depth means that each pixel can display 16,777,216 colors.

In practical applications, the broadcast control configuration information may further include other information according to needs, which is not limited in this embodiment.

In step 202, the obtaining manner of the target color gamut configured by the user may be that the master control end provides a configuration interface, and the target color gamut configured by the user is obtained through the configuration interface. Based on the target color gamut configured by the user, standard graphics card configuration information corresponding to the target color gamut and standard broadcasting control configuration information corresponding to the target color gamut in step 204 may be queried from the standard configuration data.

The image is transmitted to the playing control processing device by the rendering device based on the sequence of the image transmission links in the color calibration flow, so that the display card of the rendering device is configured first, and then the playing control configuration of the playing control processing device is performed. The main control terminal can control the display card configuration of the rendering device to be updated into standard display card configuration information, and the method can comprise the situation that the main control terminal directly sends the standard display card configuration information to the rendering device and the rendering device updates the display card configuration into the standard display card configuration information.

In other examples, the rendering device runs an interactive program that interfaces with the master; the updating the display card configuration of the rendering device to the standard display card configuration information may include:

Receiving current display card configuration information of the rendering equipment sent by the interactive program, and judging whether the standard display card configuration information is the same as the current display card configuration information;

and if the display card configuration information is different, sending the standard display card configuration information to the interactive program, and updating the display card configuration of the rendering device to the standard display card configuration information by the interactive program.

In this embodiment, the interactive program interfaces with the master control end, and the master control end may send an instruction for obtaining the current graphics card configuration information of the rendering device to the interactive program, and after receiving the instruction, the interactive program obtains the current graphics card configuration information of the rendering device and sends the current graphics card configuration information to the master control end. Therefore, the main control terminal can judge whether the standard display card configuration information is the same as the current display card configuration information. Under different conditions, the main control end can send the standard display card configuration information to the interactive program, and the interactive program updates the display card configuration of the rendering device to the standard display card configuration information. Through the cooperation of the main control end and the interactive program, the main control end can control the display card configuration of different rendering devices.

Optionally, the method of this embodiment may further include: and responding to the completion of the display card configuration updating of the rendering equipment, and outputting an updating completion prompt message for updating the display card configuration of the rendering equipment into standard display card configuration information to a user. In practical application, the update completion prompt message may be implemented in various manners, for example, may be a text prompt, a popup prompt, or may further include an audio prompt as required, which is not limited in this embodiment. Optionally, the update completion prompt message may include standard graphic card configuration information, so that the user may intuitively review the graphic card configuration of the rendering device.

In practical application, the main control machine can be connected with a plurality of rendering devices, and the main control end can control the display card configuration of each rendering device to be updated into corresponding standard display card configuration information.

And then, the master control terminal can control the broadcast control configuration of the broadcast control processing equipment to update into the standard broadcast control configuration information, wherein the method can comprise the condition that the master control terminal directly sends the standard broadcast control configuration information to the broadcast control processing equipment, and the broadcast control processing equipment updates the broadcast control configuration into the standard broadcast control configuration information.

In some examples, the broadcast control processing device runs a broadcast control program;

the controlling the broadcast control configuration update of the broadcast control processing device to the standard broadcast control configuration information may include:

receiving current broadcast control configuration information of the broadcast control processing equipment sent by the broadcast control program, and judging whether the standard broadcast control configuration information is the same as the current broadcast control configuration information;

and if the standard broadcast control configuration information is different, the standard broadcast control configuration information is sent to the broadcast control program, and the broadcast control program updates the broadcast control configuration of the broadcast control processing equipment into the standard broadcast control configuration information.

In this embodiment, the broadcast control program interfaces with the master control end, and the master control end may send an instruction for obtaining current broadcast control configuration information of the broadcast control processing device to the broadcast control program, and after the broadcast control program receives the instruction, the broadcast control program obtains the current broadcast control configuration information and sends the current broadcast control configuration information to the master control end. Therefore, the master control terminal can judge whether the standard broadcast control configuration information is the same as the current broadcast control configuration information. In different cases, the master control end can send the standard broadcast control configuration information to the broadcast control program, and the broadcast control program updates the broadcast control configuration to the standard broadcast control configuration information. By matching the master control end with the broadcast control program, the master control end can control the broadcast control configuration of the broadcast control processing device. Optionally, in practical application, the broadcast control program and the master control end are not the same manufacturer, and the broadcast control program provides an interaction interface, and the master control end provides the interaction interface provided by the broadcast control program for interaction.

Optionally, the method of this embodiment may further include: and responding to the completion of the broadcast control configuration updating of the broadcast control processing equipment, and outputting an updating completion prompt message for updating the broadcast control configuration of the broadcast control processing equipment into standard broadcast control configuration information to a user. In practical application, the update completion prompt message may be implemented in various manners, for example, may be a text prompt, a popup prompt, or may further include an audio prompt as required, which is not limited in this embodiment. Optionally, the update completion prompt message may include standard broadcast control configuration information, so that the user may intuitively review the broadcast control configuration of the broadcast control processing device.

In practical application, the main control machine can be connected with a plurality of broadcast control processing devices, and the main control end can control the broadcast control configuration of each broadcast control processing device to be updated into corresponding standard broadcast control configuration information.

After the broadcasting control configuration of the broadcasting control device is completed, the accuracy of parameter setting of the shooting device needs to be ensured. In step 206, the master may send one or more raw colors to the rendering device, which may be configured by the user, e.g., the master may provide a configuration interface through which the one or more raw colors configured by the user are obtained. The main control terminal can automatically generate a plurality of original colors by utilizing the color generation rule, and the embodiment does not limit the original colors and specific colors, and can be configured according to the needs in practical application.

As an example, a color may be represented by a color value, such as an RGB (RED, green, blue, RED Green Blue) value; under the Rec.709 color gamut, it can be expressed in 8 bits (bits) in general, i.e., each color channel has a value ranging from 0 to 255; under the Rec.2020 gamut, it can be expressed in 10 bits, i.e. each color channel has a value in the range of 0 to 1023; alternatively, the color value may be represented by a normalized value, which is not limited in this embodiment.

In practical application, there may be a plurality of original colors, and the master control end may execute the following procedure in a circulating manner for each original color: sending out an original color, analyzing the difference between the original color and the acquired color when acquiring the acquired color of the acquired image of the shooting equipment, and prompting a user to adjust shooting parameters of the shooting equipment; and then, the main control end returns to execute the steps to send out the next original color until all the original colors are sent out.

Specifically, the main control end sends an original color to the rendering device, the display screen displays a corresponding rendering image, and the shooting device shoots the rendering image displayed by the display screen and transmits an acquisition signal to the main control end in real time; the main control terminal receives the acquisition signal transmitted by the shooting equipment, analyzes the acquisition image and extracts the acquisition color from the acquisition image; and calculating the difference between the original color and the acquisition color, and determining whether the shooting parameters of the shooting equipment need to be adjusted or not based on the difference. For example, the difference is small, it is determined that there is no need to adjust the photographing parameters of the photographing apparatus. If the difference is large, determining that the shooting parameters of the shooting equipment need to be adjusted, and prompting a user to adjust the shooting parameters of the shooting equipment; after the user adjusts, the shooting equipment can continue shooting, and then the main control end can also continue to continuously acquire the acquired image until the difference between the original color and the acquired color is smaller, and the shooting parameters of the shooting equipment are determined to be unnecessary to adjust. After that, the master control side may acquire the next original color, and return to the step of "sending out an original color … … to determine that the shooting parameters of the shooting device do not need to be adjusted" described above.

In other examples, after the main control terminal continuously sends out a plurality of colors, the main control terminal obtains the collected colors of a plurality of images collected by the photographing device, analyzes the differences between a plurality of original colors and a plurality of collected colors one by one or integrally, and then outputs a prompt based on the differences.

As an example, the prompting the user to adjust the shooting parameters of the shooting device according to the difference between the original color and the acquired color may include:

and acquiring the color difference between the original color and the acquired color, and outputting a prompt message for adjusting shooting parameters of the shooting equipment based on the color difference to a user in response to the color difference being larger than a set threshold.

The threshold value of the present embodiment may be configured according to actual needs, and the present embodiment is not limited to this. As such, when the color difference between the original color and the acquisition color is large, the configuration of the photographing parameters of the photographing apparatus may be problematic, resulting in a large photographing error of the photographing apparatus, and thus, a prompt message for adjusting the photographing parameters of the photographing apparatus may be output. Optionally, the prompting message may include a color difference value, etc., and may also include information such as a corresponding adjustment suggestion.

Optionally, the prompting message may be implemented in various manners, for example, may be a text prompt, a popup prompt, or may further include an audio prompt if necessary, which is not limited in this embodiment. The content included in the hint message is not limited in this embodiment, and may be configured as needed.

In some examples, the raw colors may include raw colors of one or more of the following categories: at least one original color of the gray class and at least one original color of any one of the three color channels;

the obtaining the color difference between the original color and the collected color, and in response to the color difference being greater than a set threshold, outputting a prompt message to a user to adjust a shooting parameter of the shooting device based on the color difference may include:

for each category, acquiring the color difference of each original color in the category and the corresponding acquired color respectively, and further calculating the average color difference of the category based on the acquired color differences;

and outputting a prompt message for adjusting the shooting parameters of the shooting equipment based on the average chromatic aberration of the category to a user in response to the average chromatic aberration of the category being larger than a set threshold.

In this embodiment, one or more original colors may be included for gray scale, so that overall analysis may be performed on the acquired image of the photographing apparatus in the dimension of gray scale to determine whether the photographing parameters of the photographing apparatus in brightness need to be adjusted. For each of the three color channels, one or more original colors may be included; an overall analysis may be performed in the dimensions of each color channel for the captured image of the capture device to determine whether the capture parameters of the capture device need to be adjusted.

For example, for a gray class, the original color may include n gray colors, n collected images corresponding to the n gray colors may be obtained, chromatic aberration of each gray color of the n gray colors and the corresponding collected color is calculated to obtain n chromatic aberration, and an average value of the n chromatic aberration is calculated to obtain an average chromatic aberration; the average color difference can be compared with a first set threshold (the specific numerical value can be flexibly configured according to the requirement), so that whether the acquisition of the gray level by the shooting equipment is problematic or not can be obtained. Optionally, the output prompt message may be configured as required, for example, the prompt message may include the calculated average color difference, so that the user correspondingly adjusts the shooting parameters of the shooting device based on the average color difference.

The color three-channel comprises an R channel, a G channel and a B channel, and the treatment of each channel is the same as the treatment of the gray level class; for example, for m original colors of the R channel, m collected images corresponding to the m original colors may be obtained, chromatic aberration of each original color of the m original colors and the corresponding collected color is calculated to obtain m chromatic aberration, and an average value of the m chromatic aberration is calculated to obtain an average chromatic aberration of the R channel; the comparison of the average color difference with the second set threshold (where the second set threshold may be the same as or different from the first set threshold described above, and this embodiment is not limited to this), so it may be obtained whether the capturing device has a problem in capturing the R channel, for example, the average color difference is larger, which indicates that the capturing device captures a reddish color, etc., and of course, the reddish color may also be set by the user based on the actual capturing needs. Optionally, the output prompt message may be configured as required, for example, the prompt message may include the calculated average color difference, so that the user determines whether to correspondingly adjust the shooting parameters of the shooting device based on the average color difference. The processing of the G channel and the B channel is the same, and a detailed description is omitted here.

In practical application, the main control end can send a plurality of original colors of each category to the rendering device, after the display displays the rendering image, the main control end obtains a plurality of collected colors of the category, performs overall analysis of the category, and if the shooting device is analyzed to have problems on image collection of the category, outputs a corresponding prompt message, and can determine whether to adjust or not; optionally, after outputting the prompt message, an interface is provided for determining whether the user needs to adjust the shooting parameters, so as to accept the message input by the user through the interface, and determine whether the user needs to adjust the shooting parameters. Optionally, the user may input the adjustment of the shooting parameters, after the user adjusts the shooting parameters, the main control end may receive the message that the user adjusts the shooting parameters, so as to execute the foregoing processes of "sending, displaying, collecting, analyzing" of the original color again, and the like, and when it is analyzed that the shooting device has no problem on the image collection under the category, output a prompt message indicating that "the image collection under the category has no problem"; and then sending a plurality of original colors of the next category to the rendering device, and carrying out overall analysis on the color collection of the next category. In practical application, all original colors are sent out, all acquired images are acquired, and the overall analysis of each category is also optional for each category of color acquisition.

In practical application, in order to ensure that the photographing device can photograph the whole color range from low to high under the target color gamut, the original color of the embodiment may include:

(1) at least one original color of the gray class comprising: uniformly sampling a plurality of gray colors obtained in a color value range under the target color gamut;

taking the rec.709 color gamut as an example, the color value range is 0 to 255, and the number of samples can be configured according to needs, for example, any integer in the interval of 8 to 64, and the like. As an example, the sampled gray-scale colors may be: (0, 0), (16, 16), (32,32,32) … …, and the like.

(2) At least one original color of any one of the three color channels, comprising: in the color value range under the target color gamut, uniformly sampling a plurality of numerical values for each channel of the three color channels to obtain a plurality of colors corresponding to each channel respectively;

taking the rec.709 color gamut as an example, the color value range is 0 to 255, and the number of samples can be configured according to needs, for example, any integer in the interval of 8 to 64, and the like. As an example, the color of the sample may be:

for the R channel, it may include: (16,0,0), (32,0,0), (64, 0) … …, and the like;

For the G channel, it may include: (0,16,0), (0,32,0), (0,64,0) … …, and so forth;

for the B channel, it may include: (0,0,16), (0,0,32), (0,0,64) … …, and so forth.

Optionally, how to prompt the user to adjust the shooting parameters of the shooting device based on the difference between the two may have various implementation manners; for example, the present embodiment may focus on a color range of an acquisition color of a photographing apparatus, for example, taking a normalized acquisition color value as an example, where the color range is 0 to 1, and it is necessary to ensure that the photographing apparatus can acquire a lowest value and a highest value in the color range as much as possible, in particular, the photographing apparatus may not acquire the lowest value 0 due to light or the like, and it is acceptable near the lowest value, for example, the acquisition color of the photographing apparatus is a value closer to 0 at the lowest value; but it is necessary to ensure that the highest value of 1 can be acquired by the photographing apparatus.

In this way, the acquisition range of the photographing apparatus may be detected, for example, for the detection of the highest value, the original color may include a plurality of colors with the highest color values in the color range, for example, in rec.709, not normalized, and the color with the highest color value in the gray color is: (255 ), and the color with the highest color value in each color channel: (255, 0), (0,255,0), (0,0,255); for the original colors, the main control end respectively acquires corresponding acquired colors and normalizes the acquired colors, and the acquired colors are required to be ensured to be: (1, 1), (1, 0), (0, 1, 0), (0, 1). If the color of the acquired color does not reach the highest value, the main control end can output a corresponding prompt, for example, a prompt that the acquired color does not reach the highest value, such as a prompt that the gray scale does not reach the highest value, the R channel does not reach the highest value, the G channel does not reach the highest value, or the B channel does not reach the highest value, and the like. Alternatively, the corresponding adjustment advice may be output, for example, the reason that the acquired color does not reach the highest value may be caused by insufficient exposure, etc., and advice such as "turn up the aperture", "increase the exposure" may be output.

As an example, the original color includes a color having the highest color value in the color range under the target color gamut; taking 0-255 as an example, the color with the highest color value is (255 ). Taking normalization as an example, the highest value in the original color is (1, 1), and for ensuring that the shooting equipment can acquire the highest value, for acquiring the color (r, g, b), the main control end can determine whether the minimum value in the three colors of r, g and b is greater than or equal to the highest color value in the color range; if the minimum value of r, g and b is equal to or equal to 1, determining that the shooting equipment can acquire the color with the highest value; if not, the shooting device can be determined that the color with the highest value can not be acquired, and a corresponding prompt can be output so that a user can correspondingly adjust shooting parameters of the shooting device.

Similarly, for detection of the lowest value, one or more colors, such as (0, 0), with the lowest value in the color range may be included in the original color. Similarly, the main control end respectively acquires corresponding acquisition colors and determines whether the acquisition colors can reach a preset low value threshold. If the prompt is not reached, the main control end can output the corresponding prompt.

Optionally, the shooting parameters of the shooting device may include parameters such as an acquisition frame rate, exposure, output color gamut, or output gamma; the prompt message output by the main control terminal can contain adjustment advice of any parameter.

Optionally, the prompting message may be implemented in various manners, for example, may be a text prompt, a popup prompt, or may further include an audio prompt if necessary, which is not limited in this embodiment.

As shown in fig. 2B, an application schematic diagram is shown in the embodiment of the present disclosure, where the virtual shooting system includes a main control unit, a rendering device, a playing control processing device, and a display screen, where the above devices may be connected by a router or the like, and the camera may also be connected by a router or an SDI or the like to the main control unit. The main control terminal is operated in the main control machine, and can apply the scheme of the foregoing embodiment, so as to automatically detect and set the display card configuration of the rendering device, and also automatically detect and set the broadcast control configuration of the broadcast control processing device. Configuration adjustment prompts for the camera may also be output to enable a user to adjust the configuration of the camera based on the prompts.

As can be seen from the above embodiments, the main control end of the present embodiment may detect and analyze the software and hardware system that affects the accuracy of color calibration in the color calibration process, and prompt the user to give a modification suggestion or automatic modification for the configuration of errors or possible color accuracy reduction, so as to improve the success rate and accuracy of color calibration. Before color calibration, parameter configuration detection and configuration are carried out on a display card of rendering equipment and a broadcast control processing equipment through a color gamut selected by color calibration, so that the method is efficient and accurate; the display card configuration of each rendering device and the broadcast control configuration of the broadcast control processing device are prevented from being manually configured, and the method is low in efficiency and easy to make mistakes. And the clear conditions and detection means of the camera parameter setting standard are provided, namely, a plurality of detection color cards are rendered on a display screen, and color values are analyzed after the camera is acquired. In the scheme of the embodiment, the whole link can be detected before the color calibration is carried out, and the whole link configuration is confirmed to be correct and then the color calibration is carried out, so that the success rate and the accuracy of the virtual shooting color calibration are improved.

When the main control end determines that the difference between the original color and the acquired color is smaller, the main control end indicates that the setting of shooting parameters of the shooting equipment is correct, and a corresponding prompt can be output, so that a user can execute a further color calibration flow.
