BRIEF DESCRIPTION OF THE DRAWINGS

[0025] In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the drawings required for use in the embodiments or the description of the prior art will be briefly introduced below. Obviously, the drawings described below are only some embodiments of the present invention. For ordinary technicians in this field, other drawings can be obtained based on these drawings without paying creative work.

[0026] Figure 1 It is a schematic diagram of the system structure connection of the present invention. DETAILED DESCRIPTION

[0027] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0028] See also Figure 1 As shown, the present invention provides a film and television image post-processing three-dimensional system, which includes: a real-time rendering module, an interactive performance module, a display parameter acquisition module, a personalized display module, an early warning terminal and a database.

[0029] The real-time rendering module is connected to the interactive performance module, the interactive performance module is connected to the early warning terminal and the database respectively, the display parameter acquisition module is connected to the personalized display module, and the personalized display module is connected to the early warning terminal and the database respectively.

[0030] The real-time rendering module is used to achieve real-time rendering of film and television images in a designated place through virtual display and augmented reality technology.

[0031] In a specific embodiment, the real-time rendering of film and television images in a designated place is achieved, and the specific implementation process is as follows: a complete virtual scene is created using three-dimensional technology, the virtual scene includes the geometric shape, material properties and light source settings of the objects, and each camera perspective is set in the virtual scene, and each camera perspective is arranged around the axis position, height and angle of the virtual scene to capture each perspective of the virtual scene, and a rendering path is set for each camera perspective. The rendering path includes determining the emission direction of light and the interaction method between light and objects in the virtual scene. The rendering engine simulates the propagation of light by emitting light from the observer's position. Each light ray is emitted from the observer's position through the pixel position to the display scene in the designated place, thereby simulating the propagation and reflection of light in the display scene, thereby achieving the shadow effect of the film and television image, so as to achieve the purpose of real-time rendering of the film and television image in the designated place.

[0032] It should be noted that the rendering paths of each camera perspective are different to adapt to different perspective requirements and lighting conditions. Parallel computing technology in computer graphics is used to simultaneously process rendering tasks of multiple camera perspectives. These shadow effects can vary depending on the perspective, enhancing the realism and visual effects of the picture. When the main light intersects the surface of the object, the position of the intersection and the direction of the normal are obtained. The intersection is the specific position where the light intersects the surface of the object, and the normal is the direction perpendicular to the surface. Ray tracing can simulate global illumination effects, including indirect illumination and subsurface scattering, making the lighting in the scene look more natural and realistic. In dynamic scenes, ray tracing technology can handle the interaction between dynamic light sources and objects, and update the light and shadow effects in real time.

[0033] It should also be noted that the observer position refers to the viewpoint or camera position of the scene. In 3D rendering, this position determines the angle and position from which the entire scene is observed. The observer position is usually the position of the camera in the virtual world. It defines the starting point of the line of sight, that is, the emission point of the light in the ray tracing algorithm. The pixel position refers to the position of each individual pixel on the display screen. During the rendering process, the image is divided into pixels, and the rendering system calculates the color value for each pixel. The pixel position corresponds to each pixel on the screen, which determines the direction and target position of the light calculated by the ray tracing algorithm.

[0034] The interactive performance module is used to obtain the user interactive performance parameters corresponding to the post-production three-dimensional rendering of film and television images in the specified place, and then analyze the interactive performance evaluation coefficient corresponding to the display scene in the specified place, thereby analyzing whether the corresponding comprehensive performance level during the post-production three-dimensional rendering of the film and television images meets the set requirements.

[0035] In a specific embodiment, the user interaction performance parameters corresponding to the post-production 3D rendering of the film and television images in the designated place are obtained, and the specific acquisition process is as follows: the user interaction performance parameters include rendering frame rate, interaction response time and rendering quality index;

[0036] By inputting the specified command line at the input of the software interface, the rendering frame rate and rendering quality index corresponding to the post-production three-dimensional rendering of the film and television images in the specified place are obtained. Each monitoring position is set in front of the display scene in the specified place. The user completes each specified gesture action at each monitoring position, and the time point of completing each specified gesture action is recorded, which is recorded as the first time point. The time point corresponding to the instruction corresponding to each specified gesture action is recorded when the processing system displays the record, which is recorded as the second time point. The first time point is subtracted from the second time point, and the result obtained is the interaction response time. The corresponding time of each interaction is obtained by analysis, and each interaction response time is calculated by the mean, and the result obtained is the interaction response time corresponding to the post-production three-dimensional rendering of the film and television images in the specified place.

[0037] It should be noted that when performing post-production 3D rendering of film and television, rendering software or rendering engines are usually used to generate images. The rendering software or rendering engine usually provides the function of real-time display of the current frame rate. The rendering quality index is the display screen resolution corresponding to the post-production 3D rendering of the film and television image.

[0038] In a specific embodiment, the analysis obtains the interaction performance evaluation coefficient corresponding to the display scene in the specified place, and the specific analysis process is as follows: obtaining standard user interaction performance parameters corresponding to the post-production three-dimensional rendering of the film and television image from the database, the standard user interaction performance parameters including standard rendering frame rate, standard interaction response time and standard rendering quality index;

[0039] According to the calculation formula The interactive performance evaluation coefficient α corresponding to the display scene in the specified place is obtained, where f, T, and X respectively represent the rendering frame rate, interactive response time, and rendering quality index corresponding to the post-three-dimensional rendering of the film and television images in the specified place, f′, T′, and x′ respectively represent the standard rendering frame rate, standard interactive response time, and standard rendering quality index, and η1, η2, and η3 are the weight factors corresponding to the set rendering frame rate, the weight factor corresponding to the interactive response time, and the weight factor corresponding to the rendering quality index, respectively.

[0040] It should be noted that the values ​​of η1, η2, and η3 are all greater than 0 and less than 1.

[0041] It should also be noted that the number of rendering frame rate failures, interactive response time failures, and rendering quality index failures corresponding to the corresponding comprehensive performance level that does not meet the set requirements during the post-production three-dimensional rendering of film and television images is obtained from the database, and the total number of failures is accumulated. The number of rendering frame rate failures, the number of interactive response time failures, and the number of rendering quality index failures are divided by the total number of failures, and the results obtained are the weight factors corresponding to the set rendering frame rate, the weight factors corresponding to the interactive response time, and the weight factors corresponding to the rendering quality index. The number of rendering frame rate failures refers to the absolute value calculation of the difference between the rendering frame rate and the standard rendering frame rate, and the result obtained is greater than the rendering frame rate setting comparison value. The number of interactive response time failures refers to the standard interactive response time minus the interactive response time, and the result obtained is less than the interactive response time setting comparison value. The number of rendering quality index failures refers to the absolute value calculation of the difference between the rendering quality index and the standard rendering quality index, and the result obtained is greater than the rendering quality index setting comparison value.

[0042] In a specific embodiment, the analysis of whether the corresponding comprehensive performance level during the post-production three-dimensional rendering of the film and television image meets the set requirements is as follows: the interactive performance evaluation coefficient corresponding to the display scene in the designated place is compared with the set interactive performance evaluation coefficient threshold. If the interactive performance evaluation coefficient corresponding to the display scene in the designated place is greater than or equal to the set interactive performance evaluation coefficient threshold, it means that the corresponding comprehensive performance level during the post-production three-dimensional rendering of the film and television image meets the set requirements. If the interactive performance evaluation coefficient corresponding to the display scene in the designated place is less than the set interactive performance evaluation coefficient threshold, it means that the corresponding comprehensive performance level during the post-production three-dimensional rendering of the film and television image does not meet the set requirements, and then the rendering frame rate and rendering quality index corresponding to the post-production three-dimensional rendering of the film and television image in the designated place are adjusted until the interactive performance evaluation coefficient corresponding to the display scene in the designated place is greater than or equal to the set interactive performance evaluation coefficient threshold.

[0043] In a specific embodiment, the adjustment of the rendering frame rate and the rendering quality index corresponding to the post-production three-dimensional rendering of the film and television image in the designated place is specifically carried out as follows: when the interactive performance evaluation coefficient corresponding to the display scene in the designated place is less than the set interactive performance evaluation coefficient threshold, the interactive performance evaluation coefficient corresponding to the display scene in the designated place that is less than the set interactive performance evaluation coefficient threshold is recorded as an unqualified interactive performance evaluation coefficient, and each corresponding historical interactive performance evaluation coefficient in the historical data and each historical user interactive performance parameter corresponding to the historical interactive performance evaluation coefficient are obtained from the database, each historical interactive performance evaluation coefficient obtained from the database is greater than the unqualified interactive performance evaluation coefficient and less than the set interactive performance evaluation coefficient threshold, and each historical user interactive performance parameter includes each historical rendering frame rate, each historical interactive response time, and each historical rendering quality index;

[0044] Subtract and calculate the absolute value of each historical rendering frame rate from the standard rendering frame rate, and select the minimum result from the obtained results, so that the rendering frame rate corresponding to the post-three-dimensional rendering of the film and television images in the specified place is adjusted to the historical rendering frame rate corresponding to the minimum result; subtract and calculate the absolute value of each historical rendering quality index from the standard rendering quality index, and calculate the minimum result from the obtained results, so that the rendering quality index corresponding to the post-three-dimensional rendering of the film and television images in the specified place is adjusted to the historical rendering quality index corresponding to the minimum result, thereby completing the adjustment of the rendering frame rate and rendering quality index corresponding to the post-three-dimensional rendering of the film and television images in the specified place.

[0045] The display parameter collection module is used to monitor the corresponding screen display influencing parameters in a designated place in real time. The screen display influencing parameters include light intensity, environmental noise and color temperature.

[0046] In a specific embodiment, the real-time monitoring of the corresponding screen display influencing parameters in the designated place is performed as follows: each monitoring point is set in the designated place, and a photometer and a decibel meter are used to monitor at each monitoring point according to the set monitoring time points to obtain the light intensity and environmental noise corresponding to each monitoring point in the designated place at each monitoring time point, and the light intensity and environmental noise corresponding to each monitoring point at each monitoring time point are calculated by the mean to obtain the average light intensity and average environmental noise corresponding to each monitoring time point in the designated place, which are recorded as g t and B t , t is the number corresponding to each monitoring time point, t = 1, 2, ..., n, n is any integer greater than 2, and n represents the total number of monitoring time points;

[0047] Use a color thermometer to monitor at each monitoring point. If there are various types of light sources at each monitoring point, count the number of light sources of each type, use the light source type ranked first as the control light source, adjust or turn off the remaining light sources, and then use the color thermometer to monitor the color temperature of each monitoring point in the specified place at each monitoring time point. The average color temperature corresponding to each monitoring time point in the specified place is obtained by average calculation, recorded as K t .

[0048] It should be noted that various types of light sources include but are not limited to parallel light sources, spotlights, and point light sources.

[0049] The personalized display module is used to analyze the corresponding screen display impact index at each monitoring time point in the designated place according to the corresponding screen display impact parameters in the designated place, thereby analyzing whether the screen display effect at each monitoring time point in the designated place meets the set requirements.

[0050] In a specific embodiment, the analysis obtains the screen display influence index corresponding to each monitoring time point in the specified place, and the specific acquisition process is as follows: obtain the corresponding standard screen display influence parameters in the specified place from the database, and the standard screen display influence parameters include standard light intensity, standard environmental noise and standard color temperature:

[0051] According to the calculation formula Get the screen display impact index β corresponding to each monitoring time point in the specified place t , where g′, B′, and K′ represent the standard light intensity, standard ambient noise, and standard color temperature, respectively; γ1, γ2, and γ3 represent the weight factors corresponding to the set light intensity, ambient noise, and color temperature, respectively.

[0052] It should be noted that the values ​​of γ1, γ2, and γ3 are all greater than 0 and less than 1.

[0053] It should also be noted that the weight factors corresponding to the historical light intensity, the historical environmental noise, and the historical color temperature corresponding to each historical screen display impact index are obtained from the database, and the median of the weight factors corresponding to each historical light intensity, the weight factors corresponding to each historical environmental noise, and the weight factors corresponding to each historical color temperature are selected to obtain the weight factors corresponding to the set light intensity, the environmental noise, and the color temperature.

[0054] In a specific embodiment, the analysis of whether the screen display effect corresponding to each monitoring time point in the designated place meets the set requirements is as follows: the screen display influence index corresponding to each monitoring time point in the designated place is compared with the set screen display influence index interval. If the screen display influence index corresponding to a certain monitoring time point in the designated place belongs to the set screen display influence index interval, it means that the screen display effect corresponding to the monitoring time point in the designated place meets the set requirements. If the screen display influence index corresponding to a certain monitoring time point in the designated place does not belong to the set screen display influence index interval, it means that the screen display effect corresponding to the monitoring time point in the designated place does not meet the set requirements. In this way, it is analyzed whether the screen display effect corresponding to each monitoring time point in the designated place meets the set requirements.

[0055] It should be noted that when the corresponding picture display effect at a certain monitoring time point in the designated place does not meet the set requirements, the staff will adjust the brightness, color contrast, and playback volume of the picture display screen in the designated place to meet the picture display requirements of the designated place at that monitoring time point.

[0056] The embodiment of the present invention monitors the screen display influencing parameters in a designated place in real time during the process of the display parameter acquisition module. The timely acquisition of parameters helps to accurately evaluate the performance of film and television images in a specific environment and provides data support for subsequent adjustments and optimizations. Through the personalized display module, the screen display influence index of the designated place at different monitoring time points is analyzed according to the screen display influencing parameters. The personalized analysis is conducive to identifying and solving the screen display effect problems that may occur at a specific time point, ensuring that the film and television images can meet the set display requirements at each time point.

[0057] The early warning terminal is used to issue early warning prompts when the corresponding comprehensive performance level in the post-production three-dimensional rendering of film and television images does not meet the set requirements and the corresponding picture display effect at a certain monitoring time point in a designated place does not meet the set requirements.
