TECHNICAL FIELD

[0002] With the progress of scientific research, virtual production technology is widely used in video shooting, and film production, advertisement shooting and the like. The core of virtual production technology is to combine real scene with virtual scene (such as the combination of the depth of field effect of real scene and the depth of field effect of virtual scene), so as to make the video or film shot more real. Since the shooting parameters of the camera equipment used are different when shooting different videos, the parameters of each virtual scene are also mostly different. It is found in practice that the parameters of virtual scene (such as the shooting parameters of virtual camera equipment) are usually obtained by adjusting according to the actual shooting situation by the production personnel, and the configuration efficiency is low.

[0070] The technical solutions in the embodiments of the present application will be described clearly and completely in combination with the drawings in the embodiments of the present application. Obviously, the described embodiments only represent some of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort also belong to the protection scope of the present application.

[0071] The embodiments of the present application relate to artificial intelligence, and the related terms and concepts of artificial intelligence will be briefly introduced as follows:

[0072] Artificial Intelligence (AI) is the use of digital computers or machines controlled by digital computers to simulate, extend and expand human intelligence, perceive the environment, acquire knowledge and use knowledge to obtain the best results. In other words, artificial intelligence is a comprehensive technology of computer science, which attempts to understand the essence of intelligence and produce a new intelligent machine that can react in a similar way to human intelligence. Artificial intelligence is to study the design principles and implementation methods of various intelligent machines, so that the machine has the functions of perception, reasoning and decision-making.

[0073] AI technology is a comprehensive discipline, involving a wide range of fields, both hardware and software technologies. Artificial intelligence basic technology generally includes technologies such as sensors, special artificial intelligence chips, cloud computing, distributed storage, large application processing technology, operation / interaction system, mechatronics, etc. Artificial intelligence software technology mainly includes computer vision technology, speech processing technology, natural language processing technology and machine learning / deep learning, etc.

[0074] Machine learning is a multi-disciplinary subject, involving probability theory, statistics, approximation theory, convex analysis, algorithm complexity theory and other disciplines. It is a subject that studies how computers simulate or implement human learning behavior to acquire new knowledge or skills, and reorganize existing knowledge structure to continuously improve their performance. Machine learning is the core of AI and the fundamental approach to making computers intelligent, and its applications are widespread in various fields of artificial intelligence. Machine learning / deep learning usually includes artificial neural networks, belief networks, reinforcement learning, transfer learning, inductive learning, and example-based learning.

[0075] Deep learning: the concept of deep learning comes from the research of artificial neural networks. Multi-layer perceptron with multiple hidden layers is a deep learning structure. Deep learning forms more abstract high-level representation attributes or features by combining low-level features to discover distributed feature representation of data. The embodiments of the present application mainly involve training an initial model by referring to a data set to obtain a virtual scene parameter prediction model; the virtual scene parameter prediction model can be used to analyze the shooting parameters of the target camera device and output the target virtual scene parameters corresponding to the virtual content to be shot by the target camera device.

[0076] The parameter configuration scheme proposed in the embodiments of the present application will be briefly introduced below. The parameter configuration scheme can improve the parameter configuration efficiency and accuracy. Please refer to Figure 1 , Figure 1 A scene graph for virtual production provided by the embodiments of the present application. As shown in Figure 1As shown, the scenario mainly includes a camera device 101 and a display device 102. The parameter configuration method provided in this application embodiment can be executed by the server 103. The camera device 101 may include, but is not limited to, smart devices with shooting functions such as smartphones (e.g., Android phones, iOS phones, etc.), tablets, cameras, and camcorders; this application embodiment does not limit this. The display device 102 may be a smart device with image rendering and display functions such as an LED screen.

[0077] It should be noted that, Figure 1 The camera device 101 and the display device 102 can be directly or indirectly connected via wired or wireless communication, and this application does not impose any limitations on this. The number of camera devices and display devices is merely illustrative and does not constitute an actual limitation of this application; for example, Figure 1 The scenario shown may also include a camera device 103 or a display device 104, etc. Optionally, the scenario may also include a server, which can determine virtual scene parameters based on the shooting parameters of the camera device 101 and send the virtual scene parameters to the display device 102 so that the display device 102 displays virtual content according to the virtual scene parameters. The server may be an independent physical server, a server cluster or distributed system composed of multiple physical servers, or a cloud server that provides basic cloud computing services such as cloud services, cloud databases, cloud computing, cloud functions, cloud storage, network services, cloud communication, middleware services, domain name services, security services, CDN (Content Delivery Network), and big data and artificial intelligence platforms. This application embodiment does not limit this.

[0078] The general principle of the parameter configuration scheme is as follows:

[0079] (1) The display device 102 acquires the shooting parameters of the camera device 101. In one embodiment, the shooting parameters include focal length, aperture value and focus value; wherein, the focus value refers to the distance between the camera device 101 and the subject being photographed by the device.

[0080] (2) The display device 102 acquires a reference dataset, which includes the correspondence between reference shooting parameters and virtual scene parameters. The reference shooting parameters describe the shooting parameters of the reference camera device (i.e., the real camera device used when configuring the reference dataset), and the virtual scene parameters describe the shooting parameters of the virtual camera device. It should be noted that by adjusting the shooting parameters of the virtual camera device, the virtual scene can be adjusted (e.g., to achieve a depth-of-field effect).

[0081] In an embodiment, the reference camera device comprises a plurality of sets of shooting parameters, and the manner of determining the correspondence between the reference shooting parameters and the virtual scene parameters is: making the reference camera device shoot the reference objects to obtain real images according to a first set of reference shooting parameters, adjusting the virtual objects corresponding to the reference objects by adjusting the virtual scene parameters, and making the reference camera device shoot the virtual objects to obtain virtual images according to the first set of reference shooting parameters, when the real images and the virtual images match (for example, the depth-of-field effect of the virtual images matches the depth-of-field effect of the real images), recording the virtual scene parameters, and establishing the correspondence between the virtual scene parameters and the first set of reference shooting parameters, wherein the first set of reference shooting parameters can be any one of the plurality of sets of shooting parameters.

[0082] In an embodiment, N reference objects are arranged in a near-to-far manner, N being an integer greater than 1; the N reference objects are located on the same straight line and have equal distances between each other; and the reference camera device shoots the N reference objects to obtain real images according to a first set of reference shooting parameters. It should be noted that when the real images are collected, the distance between the reference camera device and the closest reference object is the same as the distance between each reference object, and the reference camera device and the N reference objects are located on the same straight line. After obtaining the real images, x reference objects having a distance greater than a distance threshold from the reference camera device are removed from the N reference objects, and the removed x reference objects are simulated in the display device (that is, x virtual objects are displayed in the display device, the x virtual objects and the N-x reference objects not removed are located on the same straight line, and the display effect of the x virtual objects can be adjusted by the virtual scene parameters), and the reference camera device (at the same position as when the real images are shot) shoots the N-x reference objects remaining and the x virtual objects simulated in the display device to obtain virtual images according to the first set of reference shooting parameters. When the real images and the virtual images match, the virtual scene parameters are recorded, and the correspondence between the virtual scene parameters and the first set of reference shooting parameters is established.

[0083] For example, 10 reference objects (e.g., 10 balls) are arranged in a near-to-far manner, and the 10 reference objects are located on the same straight line and have equal distances (e.g., 2 meters) between each other. The reference camera device captures the 10 reference objects to obtain a real image according to the first set of reference shooting parameters. It should be noted that when the real image is captured, if the distance between each reference object is 2 meters, the distance between the reference camera device and the nearest reference object is also 2 meters, and the reference camera device is located on the same straight line as the 10 reference objects. After obtaining the real image, the reference objects with a distance greater than a distance threshold from the reference camera device are removed (e.g., the 5 reference objects farthest from the reference camera device are removed), and the removed 5 reference objects are simulated in the display device, that is, 5 virtual objects are displayed in the display device. The 5 virtual objects are located on the same straight line as the 5 reference objects that are not removed, and the display effect of the 5 virtual objects can be adjusted by the virtual scene parameters. The reference camera device (at the same position as when the real image is captured) captures the remaining 5 reference objects and the 5 virtual objects simulated in the display device to obtain a virtual image according to the first set of reference shooting parameters. When the real image and the virtual image match (e.g., the depth-of-field effect of the virtual image matches the depth-of-field effect of the real image), the virtual scene parameters are recorded, and a corresponding relationship between the virtual scene parameters and the first set of reference shooting parameters is established.

[0084] (3) The display device 102 determines the target virtual scene parameters corresponding to the virtual content to be captured by the camera device 101 according to the shooting parameters of the camera device 101 and the reference data set. Specifically, the display device 102 determines the target virtual scene parameters corresponding to the virtual content to be captured by the camera device 101 according to the relationship between the shooting parameters of the camera device 101 and the shooting parameters of the reference camera device, and the corresponding relationship between the shooting parameters of the reference camera device and the shooting parameters of the virtual camera device.

[0085] (4) The display device 102 displays the virtual content according to the target virtual scene parameters, so that the camera device 101 captures the virtual content.

[0086] In the embodiments of the present application, the shooting parameters of the target camera device and the reference data set are obtained, the target virtual scene parameters corresponding to the virtual content to be captured by the target camera device are determined according to the shooting parameters of the target camera device and the reference data set, the virtual content is displayed according to the target virtual scene parameters, and the target camera device captures the virtual content. It can be seen that the target virtual scene parameters corresponding to the virtual content to be captured by the target camera device are determined by the reference data set, which can improve the configuration efficiency and accuracy of the virtual scene parameters.

[0087] Based on the above parameter configuration scheme, the embodiment of the present application proposes a more detailed parameter configuration method, which will be described in detail below in combination with the drawings.

[0088] Please refer to Figure 2 , Figure 2 A parameter configuration method is provided for the embodiment of the present application, which can be executed by a computer device, which can be specifically a display device 102 as shown in Figure 1 The parameter configuration method can include the following steps S201-S204 as shown in Figure 2

[0089] S201, obtaining the shooting parameter of the target camera device.

[0090] The shooting parameter of the target camera device is the parameter used by the target camera device when shooting an image. In an embodiment, the shooting parameter includes the lens parameter of the target camera device. Specifically, the lens parameter of the target camera device can include focal length, aperture value and focal point value; wherein the focal point value refers to the distance between the target camera device and the shooting subject of the device.

[0091] S202, obtaining a reference data set.

[0092] The reference data set includes the correspondence between the reference shooting parameter and the virtual scene parameter; wherein the reference shooting parameter is used to describe the shooting parameter of the reference camera device (i.e. the real camera device used when configuring the reference data set), and the shooting parameter includes the lens parameter of the reference camera device; the virtual scene parameter is used to describe the shooting parameter of the virtual camera device, and the shooting parameter of the virtual camera device includes the lens parameter of the virtual camera device. It should be noted that by adjusting the shooting parameter of the virtual camera device, the virtual scene can be adjusted (such as adjusting the depth of field effect of the virtual scene).

[0093] S203, determining the target virtual scene parameter corresponding to the virtual content to be shot by the target camera device according to the shooting parameter of the target camera device and the reference data set.

[0094] In an embodiment, the computer device determines the target virtual scene parameter corresponding to the virtual content to be shot by the camera device 101 according to the relationship between the shooting parameter of the target camera device and the shooting parameter of the reference camera device, and the corresponding relationship between the shooting parameter of the reference camera device and the shooting parameter of the virtual camera device (i.e. the shooting parameter of the virtual camera device corresponding to the shooting parameter of the target camera device).

[0095] ​In one embodiment, the reference dataset includes M*N*P groups of shooting parameters, each group of shooting parameters including a focal length, an aperture value and a focus value, M is the number of candidate focal lengths, N is the number of candidate aperture values, and P is the number of candidate focus values, M, N and P are positive integers; the shooting parameters of the target camera device include an actual focal length, an actual aperture value and an actual focus value; and the computer device determines the target virtual scene parameters corresponding to the virtual content to be shot by the target camera device according to the shooting parameters of the target camera device and the reference dataset. The specific implementation is as follows: the actual focal length is determined as the scene focal length of the target virtual scene, and it is determined whether there is a candidate focal length consistent with the actual focal length in the M candidate focal lengths of the reference device; if the actual focal length is consistent with the i-th candidate focal length of the reference camera device, the scene aperture value and the scene focus value of the target virtual scene are determined according to the relationship between the actual aperture value and the actual focus value and the candidate aperture value and the candidate focus value associated with the i-th candidate focal length; if the actual focal length is between the i-th candidate focal length and the i+1-th candidate focal length of the reference camera device, the scene aperture value and the scene focus value of the target virtual scene are determined according to the relationship between the actual aperture value and the actual focus value and the candidate aperture value and the candidate focus value associated with the i-th candidate focal length, and the relationship between the actual aperture value and the actual focus value and the candidate aperture value and the candidate focus value associated with the i+1-th candidate focal length; wherein i is a positive integer less than M.

[0096] In another embodiment, the computer device trains an initial model through the reference dataset to obtain a virtual scene parameter prediction model; the shooting parameters of the target camera device are analyzed through the virtual scene parameter prediction model, and the target virtual scene parameters corresponding to the virtual content to be shot by the target camera device are output. The process of training the initial model through the reference dataset to obtain the virtual scene parameter prediction model is as follows: the shooting parameters of the reference camera device are analyzed through the initial model to predict the shooting parameters of the virtual camera device; the loss value of the predicted shooting parameters of the virtual camera device and the shooting parameters of the virtual camera device corresponding to the shooting parameters of the reference camera device is calculated through a loss function, and the parameters in the initial model are adjusted based on the loss value to obtain the virtual scene parameter prediction model.

[0097] S204, displaying the virtual content according to the target virtual scene parameters.

[0098] The computer device displays the virtual content according to the target virtual scene parameters, and the target camera device shoots the virtual content displayed in the computer device to obtain a virtual production image.

[0099] In the embodiment of the present application, the shooting parameters of the target camera device and the reference data set are acquired, the target virtual scene parameters corresponding to the virtual content to be shot by the target camera device are determined according to the shooting parameters of the target camera device and the reference data set, the virtual content is displayed according to the target virtual scene parameters, and the target camera device is caused to shoot the virtual content. It can be seen that the target virtual scene parameters corresponding to the virtual content to be shot by the target camera device are determined by referring to the reference data set, which can improve the configuration efficiency and accuracy of the virtual scene parameters.

[0100] Please refer to Figure 3 , Figure 3 Another parameter configuration method is provided in the embodiment of the present application, which can be executed by a computer device, and the computer device can be specifically the display device 102 shown in Figure 1 . As shown in Figure 3 , the parameter configuration method can include the following steps S301-S305:

[0101] S301, according to the shooting parameters of the reference camera device and the shooting parameters of the virtual camera device, a reference data set is configured.

[0102] The reference camera device includes multiple groups of shooting parameters, and the configuration process of the computer device to configure the reference data set is as follows: the first group of shooting parameters of the reference camera device is acquired, and the reference camera device is used to shoot a real image of a reference object based on the first group of shooting parameters, and the first group of shooting parameters is any one of the multiple groups of shooting parameters. On the one hand, a simulated object is obtained by simulating the reference object, and the virtual object is adjusted by adjusting the virtual scene parameters; on the other hand, the virtual object is shot by the reference camera device based on the first group of shooting parameters to obtain a virtual image. The virtual image and the real image are compared, and the target virtual scene parameters corresponding to the matching of the virtual image and the real image are recorded; the corresponding relationship between the first group of shooting parameters and the target virtual scene parameters is established, and the corresponding relationship is added to the reference data set.

[0103] In an implementation manner, the reference data set includes M*N*P groups of shooting parameters, each group of shooting parameters includes one focal length, one aperture value and one focus value, M is the number of candidate focal lengths, N is the number of candidate aperture values, and P is the number of candidate focus values, M, N and P are all positive integers; the first group of shooting parameters includes the i th candidate focal length, the j th candidate aperture value and the k th candidate focus value, i is a positive integer less than M, j is a positive integer less than N, and k is a positive integer less than P.

[0104] Figure 4a A shooting schematic diagram of a real image is provided in the embodiment of the present application. As shown in Figure 4aAs shown, 2y reference objects (such as small balls) are placed in order from near to far, all on a straight line, with a distance of x meters between each reference object. A reference camera is positioned x meters away from the first reference object. The reference camera uses the i-th candidate focal length, the j-th candidate aperture value, and the k-th candidate focus value to capture the real image. Here, x is a positive number, and y is an integer greater than or equal to P. In one specific implementation, the focus of the reference camera is set at the center of the first reference object, and the distance between the first reference object and the reference camera is determined as the first candidate focus value. Similarly, the focus of the reference camera is set at the center of the k-th reference object, and the distance between the k-th reference object and the reference camera is determined as the k-th candidate focus value. Candidate aperture values ​​may include, but are not limited to: 2.8, 4, 5.6, 8; candidate focal lengths may include, but are not limited to: 16, 24, 35, 50, 75, 105.

[0105] Figure 4b This is a schematic diagram illustrating the capture of a virtual image, as provided in an embodiment of this application. Figure 4b As shown, y reference objects (such as small balls) are arranged in order from near to far, with a spacing of x meters between each reference object. The distance between the reference camera and the first reference object is x meters, and the distance between the screen and the y-th reference object is x meters. The tangent line of the left edge of the screen coincides with that of the first virtual object on the screen. The screen contains y virtual objects arranged in order from near to far, and these y virtual objects and the y reference objects are on the same straight line, with a spacing of x meters between each virtual object. The reference camera is x meters away from the first reference object, and the reference camera uses the i-th candidate focal length, the j-th candidate aperture value, and the k-th candidate focus value to capture the virtual image.

[0106] In one implementation, the computer device adjusts the virtual object by adjusting virtual scene parameters. Specifically, the i-th candidate focal length is determined as the virtual focal length of the virtual camera device, and the virtual aperture and virtual focus values ​​of the virtual camera device are configured. When the reference camera device follows... Figure 4a The real images acquired in the method described above are compared with those from the reference camera equipment. Figure 4bWhen the virtual images collected in the above manner match (e.g., the depth-of-field effects of the two images are consistent), the computer device records the virtual focal length, the virtual aperture value and the virtual focus point value of the virtual camera device (i.e., records the virtual scene parameters), and establishes the correspondence between the virtual parameters and the i th candidate focal length, the j th candidate aperture value and the k th candidate focus point value (a set of shooting parameters). The above method is repeated to obtain the virtual scene parameters corresponding to M*N*P sets of shooting parameters. Table 1 is a schematic table provided by an embodiment of the present application for recording the virtual scene parameters corresponding to each set of shooting parameters:

[0107] Table 1

[0108]

[0109] As shown in Table 1, when the candidate focal length is A1, the candidate aperture value is B1, and the candidate focus point value is C1, the virtual scene parameters are: A1, D1, E1; where A1 is the virtual focal length, D1 is the virtual aperture value, and E1 is the virtual focus point value. One candidate focal length, one candidate aperture value and one candidate focus point value form a set of shooting parameters of the reference camera device, and each set of shooting parameters of the reference camera device has an index function, i.e., each set of shooting parameters of the reference camera device corresponds to unique virtual scene parameters; for example, the virtual scene parameters corresponding to A1, B1 and C1 are A1, D1 and E1.

[0110] It should be noted that in Table 1, the order of the candidate focal length, the candidate aperture value and the candidate focus point value can be changed, for example, the order of the candidate aperture value and the candidate focus point value is changed; the order in Table 1 represents that under each candidate aperture value, different candidate focus point values correspond to virtual scene parameters, and changing the order of the candidate aperture value and the candidate focus point value represents that under each candidate focus point value, different candidate aperture values correspond to virtual scene parameters. Optionally, since the candidate focal length is consistent with the virtual focal length, the virtual focal length can also be omitted in the virtual scene parameters.

[0111] S302, obtain the shooting parameters of the target camera device.

[0112] S303, obtain the reference data set.

[0113] The specific implementation of steps S302 and S303 can refer to the implementation of steps S201 and S202 in Figure 2 The implementation of steps S201 and S202 in

[0114] S304, determine the target virtual scene parameters corresponding to the virtual content to be shot by the target camera device according to the relationship between the shooting parameters of the target camera device and the shooting parameters of the reference camera device, and the correspondence between the shooting parameters of the reference camera device and the shooting parameters of the virtual camera device.

[0115] The computer device determines the actual focal length as a scene focal length of a target virtual scene corresponding to the virtual content to be photographed by the target camera device; for example, assuming that the actual focal length of the target camera device is 16mm, the computer device configures the scene focal length of the target virtual scene corresponding to the virtual content to be photographed by the target camera device as 16mm.

[0116] S11: The computer device determines whether there is a candidate focal length identical to the actual focal length of the target camera device in the M candidate focal lengths of the reference camera device.

[0117] If the actual focal length of the target camera device is consistent with the i-th candidate focal length of the reference camera device, i is a positive integer less than M, the computer device determines the scene aperture value and the scene focal point value of the target virtual scene according to the relationship between the actual aperture value and the actual focal point value and the candidate aperture value and the candidate focal point value associated with the i-th candidate focal length, for details, see step S12.

[0118] If the actual focal length of the target camera device is between the i-th candidate focal length and the i+1-th candidate focal length of the reference camera device (such as the i-th candidate focal length < actual focal length < i+1-th candidate focal length), i is a positive integer less than M, the computer device determines the scene aperture value and the scene focal point value of the target virtual scene according to the relationship between the actual aperture value and the actual focal point value and the candidate aperture value and the candidate focal point value associated with the i-th candidate focal length, and the relationship between the candidate aperture value and the candidate focal point value associated with the i+1-th candidate focal length, for details, see step S15.

[0119] S12: In the case where the actual focal length of the target camera device is consistent with the i-th candidate focal length of the reference camera device, the computer device determines whether there is a candidate aperture value identical to the actual aperture value of the target camera device in the N candidate aperture values of the reference camera device.

[0120] If the actual aperture value of the target camera device is consistent with the j-th candidate aperture value associated with the i-th candidate focal length of the reference camera device, j is a positive integer less than N, the computer device determines the scene aperture value and the scene focal point value of the target virtual scene according to the relationship between the actual focal point value of the target camera device and the candidate focal point value associated with the j-th candidate aperture value associated with the i-th candidate focal length of the reference camera device, for details, see step S13.

[0121] If the actual aperture value of the target camera device is between the jth candidate aperture value associated with the ith candidate focal length of the reference camera device and the (j+1)th aperture value associated with the ith candidate focal length of the reference camera device (e.g., the jth candidate aperture value < the actual aperture value < the (j+1)th aperture value), and j is a positive integer less than N, the computer device determines the scene aperture value and the scene focal point value of the target virtual scene according to the relationship between the actual focal point value of the target camera device and the candidate focal point value associated with the jth candidate aperture value associated with the ith candidate focal length of the reference camera device, and the relationship between the actual focal point value of the target camera device and the candidate focal point value associated with the (j+1)th aperture value associated with the ith candidate focal length of the reference camera device. Details are shown in step S14.

[0122] S13: In the case that the actual focal length of the target camera device is consistent with the ith candidate focal length of the reference camera device, and the actual aperture value of the target camera device is consistent with the jth candidate aperture value of the reference camera device, the computer device determines whether there is a candidate focal point value in the P candidate focal point values of the reference camera device that is the same as the actual focal point value of the target camera device.

[0123] If the actual focal point value of the target camera device is consistent with the kth focal point value associated with the jth candidate aperture value associated with the ith candidate focal length of the reference camera device, and k is a positive integer less than P, the computer device determines the virtual aperture value and the virtual focal point value corresponding to the kth focal point value associated with the jth candidate aperture value associated with the ith candidate focal length as the scene aperture value and the scene focal point value of the target virtual scene, respectively. Specifically, please refer to Table 1 above, the ith candidate focal length of the reference camera device is A i , the jth candidate aperture value is B j , and the kth candidate focal point value is C k , the computer device determines the scene aperture value and the scene focal point value of the virtual scene corresponding thereto from Table 1 based on A i , B j , and C k , and determines the scene aperture value and the scene focal point value of the virtual scene and the actual focal length of the target camera device as the target virtual scene parameters.

[0124] If the actual focus value of the target camera device is between the jth candidate aperture value associated with the ith candidate focal length of the reference camera device and the kth focus value associated with the jth candidate aperture value and the ith candidate focal length of the reference camera device (for example, the kth candidate focus value < the actual focus value < the k+1th candidate focus value), the computer device calculates the scene aperture value and the scene focus value of the target virtual scene according to the virtual aperture value and the virtual focus value corresponding to the kth focus value associated with the jth candidate aperture value and the ith candidate focal length of the reference camera device, and the virtual aperture value and the virtual focus value corresponding to the k+1th focus value associated with the jth candidate aperture value and the ith candidate focal length of the reference camera device. Specifically, please refer to Table 1 above, the ith candidate focal length of the reference camera device is A i , the jth candidate aperture value is B j , the kth candidate focus value is C k , and the k+1th candidate focus value is C k+1 (set C k+1 > C k ). In a specific implementation, assuming that the actual focus value of the target camera device is R1, the computer device determines from Table 1 that the scene aperture value of the virtual scene corresponding thereto is T i and the scene focus value is W j based on A k , B k and C k ; determines from Table 1 that the scene aperture value of the virtual scene corresponding thereto is T i and the scene focus value is W j based on A k+1 , B k+1 and C k+1 (set W k+1 > W k ); and then in the target virtual scene parameters:

[0125] the target scene aperture value = (T k + T k+1 ) / 2

[0126] the target scene focus value = [(R1-C k ) / (C k+1 -C k )]*(W k+1 -W k )+W k

[0127] In addition, the target scene focal length is the actual focal length of the target camera device.

[0128] S14: In a case where the actual focal length of the target camera device is consistent with the i th candidate focal length of the reference camera device, and the actual aperture value of the target camera device is between the j th candidate aperture value and the j+1 th candidate aperture value of the reference camera device, the computer device determines whether there is a candidate focal point value in the P candidate focal point values of the reference camera device that is the same as the actual focal point value of the target camera device.

[0129] If the actual focal point value of the target camera device is consistent with the k th focal point value associated with the j th candidate aperture value associated with the i th candidate focal length of the reference camera device, the virtual aperture value and the virtual focal point value corresponding to the k th focal point value associated with the j th candidate aperture value associated with the i th candidate focal length of the reference camera device, and the virtual aperture value and the virtual focal point value corresponding to the k th focal point value associated with the j+1 th candidate aperture value associated with the i th candidate focal length of the reference camera device, the computer device calculates the scene aperture value and the scene focal point value of the target virtual scene. Specifically, please refer to Table 1 above, the i th candidate focal length of the reference camera device is A i , the j th candidate aperture value is B j , the j+1 th candidate aperture value is B j+1 , and the k th candidate focal point value is C k . In a specific implementation, assuming that the actual aperture value of the target camera device is Q1, the computer device determines from Table 1 the corresponding scene aperture value T k and scene focal point value W k of the virtual scene based on A i , B j and C k ; determines from Table 1 the corresponding scene aperture value U k (assuming U k >T k ) and scene focal point value V k of the virtual scene based on A i , B j+1 (assuming B j+1 >B j ) and C k ; and then the target virtual scene parameters are:

[0130] Target scene aperture value = [(Q1-B j ) / (B j+1 -B j )]*(U k -T k )+T k

[0131] Target scene focal point value = (W k +V k ) / 2

[0132] In addition, the focal length of the target scene is the actual focal length of the target camera device.

[0133] If the actual focus value of the target camera device lies between the k-th focus value associated with the j-th candidate aperture value related to the i-th candidate focal length of the reference camera device and the (k+1)-th focus value associated with the j-th candidate aperture value associated with the i-th candidate focal length of the reference camera device, then the scene aperture value and scene focus value of the target virtual scene are calculated based on the virtual aperture value and virtual focus value corresponding to the k-th focus value associated with the j-th candidate aperture value of the i-th candidate focal length of the reference camera device, the (k+1)-th focus value associated with the j-th candidate aperture value of the i-th candidate focal length of the reference camera device, the (j+1)-th focus value associated with the j-th candidate aperture value of the reference camera device, and the (k+1)-th focus value associated with the j-th candidate aperture value of the i-th candidate focal length of the reference camera device. Specifically, please refer to Table 1 above, where the i-th candidate focal length of the reference camera device is A. i The j-th candidate aperture value is B. j The (j+1)th candidate aperture value is B. j+1 The value of the kth candidate focus is C. k The value of the (k+1)th candidate focus is C. k+1 .

[0134] In one specific implementation, let the actual focus value of the target camera be R2, the actual aperture value be Q2, and the computer device be based on A... i B j and C k From Table 1, the scene aperture value of the corresponding virtual scene is determined to be T. k The scene focus value is W. k Based on A i B j and C k+1 (Let C) k+1 >C k From Table 1, the scene aperture value for the corresponding virtual scene is determined to be T. k+1 The scene focus value is W. k+1 (Let W) k+1 >W k Based on A i B j+1 (Let B) j+1 >B j ) and C kThe scene aperture value of the corresponding virtual scene is U k , and the scene focus value is V k from Table 1 i , B j+1 and C k+1 , the scene aperture value of the corresponding virtual scene is U k+1 , and the scene focus value is V k+1 (V k+1 >V k ). The specific corresponding relationship is shown in Table 2:

[0135] Table 2

[0136]

[0137]

[0138] Based on the above Table 2, in the target virtual scene parameters:

[0139] The target scene aperture value = [(Q2-B j ) / (B j+1 -B j )]*(Z2-Z1)+Z1

[0140] Wherein, Z1 is the smaller one of (U k +U k+1 ) / 2 and (T k +T k+1 ) / 2, and Z2 is the larger one of (U k +U k+1 ) / 2 and (T k +T k+1 ) / 2.

[0141] The target scene focus value = (Z3+Z4) / 2

[0142] Wherein, Z3 = [(R2-C k ) / (C k+1 -C k )]*(W k+1 -W k )+W k , Z4 = [(R2-C k ) / (C k+1 -C k )]*(V k+1 -V k )+V k . In addition, the target scene focal length is the actual focal length of the target camera device.

[0143] S15: In the case that the actual focal length of the target camera device is between the i th candidate focal length and the i+1 th candidate focal length of the reference camera device, the computer device determines whether there is a candidate aperture value of the reference camera device which is the same as the actual aperture value of the target camera device in the N candidate aperture values of the reference camera device.

[0144] If the actual aperture value of the target camera device is the same as the j th candidate aperture value associated with the i th candidate focal length of the reference camera device, j is a positive integer less than N, the computer device determines the scene aperture value and the scene focal point value of the target virtual scene according to the relationship between the actual focal point value of the target camera device and the candidate focal point value associated with the j th candidate aperture value associated with the i th candidate focal length of the reference camera device, and the relationship between the candidate focal point value associated with the j th candidate aperture value associated with the i+1 th candidate focal length of the reference camera device, for details, see step S16.

[0145] If the actual aperture value of the target camera device is between the j th candidate aperture value associated with the i th candidate focal length of the reference camera device and the j+1 th candidate aperture value associated with the i th candidate focal length of the reference camera device, j is a positive integer less than N, the computer device determines the scene aperture value and the scene focal point value of the target virtual scene according to the relationship between the actual focal point value of the target camera device and the candidate focal point value associated with the j th candidate aperture value associated with the i th candidate focal length of the reference camera device, the relationship between the candidate focal point value associated with the j+1 th candidate aperture value associated with the i th candidate focal length of the reference camera device, the relationship between the candidate focal point value associated with the j th candidate aperture value associated with the i+1 th candidate focal length of the reference camera device, and the relationship between the candidate focal point value associated with the j+1 th candidate aperture value associated with the i+1 th candidate focal length of the reference camera device, for details, see step S17.

[0146] S16: In the case that the actual focal length of the target camera device is between the i th candidate focal length and the i+1 th candidate focal length of the reference camera device, and the actual aperture value of the target camera device is the same as the j th candidate aperture value of the reference camera device, the computer device determines whether there is a candidate focal point value of the reference camera device which is the same as the actual focal point value of the target camera device in the P candidate focal point values of the reference camera device.

[0147] If the actual focus value of the target camera device is consistent with the k-th candidate focus value associated with the j-th candidate aperture value associated with the i-th candidate focal length of the reference camera device, then the computer device calculates the scene aperture value and scene aperture value of the target virtual scene based on the virtual aperture value and virtual focus value corresponding to the k-th candidate focus value associated with the j-th candidate aperture value associated with the i-th candidate focal length, and the virtual aperture value and virtual focus value corresponding to the k-th candidate focus value associated with the j-th candidate aperture value associated with the (i+1)-th candidate focal length. Specifically, please refer to Table 1 above, where the i-th candidate focal length of the reference camera device is A. i The (i+1)th candidate focal length is A i+1 The j-th candidate aperture value is B. j The value of the kth candidate focus is C. k In one specific implementation, let the actual focus value of the target camera be FS1, and let the computer device be based on A... i B j and C k From Table 1, the scene aperture value of the corresponding virtual scene is determined to be T. k The scene focus value is W. k Based on A i+1 B j and C k From Table 1, the scene aperture value of the corresponding virtual scene is determined to be HA. k The scene focus value is HB. k Then, in the target virtual scene parameters:

[0148] Target scene aperture value = (T k +HA k ) / 2

[0149] Target scene focus value = (W k +HB k ) / 2

[0150] In addition, the focal length of the target scene is the actual focal length of the target camera device (i.e., FS1).

[0151] If the actual focus value of the target camera device is between the kth candidate focus value associated with the jth candidate aperture value associated with the ith candidate focal length and the k+1th candidate focus value associated with the jth candidate aperture value associated with the ith candidate focal length, the computer device calculates the scene aperture value and the scene focus value of the target virtual scene according to the virtual aperture value and the virtual focus value corresponding to the kth candidate focus value associated with the jth candidate aperture value associated with the ith candidate focal length, the virtual aperture value and the virtual focus value corresponding to the k+1th candidate focus value associated with the jth candidate aperture value associated with the ith candidate focal length, the virtual aperture value and the virtual focus value corresponding to the kth candidate focus value associated with the jth candidate aperture value associated with the ith+1th candidate focal length, and the virtual aperture value and the virtual focus value corresponding to the k+1th candidate focus value associated with the jth candidate aperture value associated with the ith+1th candidate focal length. Specifically, referring to Table 1 above, the ith candidate focal length of the reference camera device is A i , the ith+1th candidate focal length is A i+1 , the jth candidate aperture value is B j , the kth candidate focus value is C k , and the k+1th candidate focus value is C k+1 .

[0152] In a specific implementation, assuming that the actual focus value of the target camera device is FS2, the actual focus value is R3, the computer device determines, based on A i , B j , and C k , from Table 1, that the scene aperture value of the corresponding virtual scene is T k , and the scene focus value is W k ; determines, based on A i , B j , and C k+1 (assuming that C k+1 > C k ), from Table 1, that the scene aperture value of the corresponding virtual scene is T k+1 , and the scene focus value is W k+1 (assuming that W k+1 > W k ); determines, based on A i+1 , B j , and C k , from Table 1, that the scene aperture value of the corresponding virtual scene is HA k , and the scene focus value is HB k ; and determines, based on A i+1 , B j , and C k+1 , from Table 1, that the scene aperture value of the corresponding virtual scene is HAk+1 , the scene focal point value is HB k+1 (set HB k+1 > HB k ); the specific corresponding relationship is shown in Table 3:

[0155] Based on the above Table 3, in the target virtual scene parameters:

[0156] The target scene aperture value = (Z5+Z6) / 2

[0157] Wherein, Z5 = (T k +T k+1 ) / 2, Z6 = (HA k +HA k+1 ) / 2.

[0158] The target scene focal point value = (Z7+Z8) / 2

[0159] Wherein, Z7 = [(R3-C k ) / (C k+1 -C k )]*(W k+1 -W k )+W k , Z8 = [(R3-C k ) / (C k+1 -C k )]*(HB k+1 -HB k )+HB k In addition, the target scene focal length is the actual focal length of the target camera device (i.e. FS2).

[0160] S17: In the case that the actual focal length of the target camera device is between the i th candidate focal length and the i+1 th candidate focal length of the reference camera device, and the actual aperture value of the target camera device is between the j th candidate aperture value associated with the i th candidate focal length and the j+1 th candidate aperture value associated with the i th candidate focal length of the reference camera device, the computer device determines whether there is a candidate focal point value identical to the actual focal point value of the target camera device in the P candidate focal point values of the reference camera device.

[0161] If the actual focus value of the target camera device is consistent with the jth candidate aperture value associated with the ith candidate focal length of the reference camera device and the kth candidate focus value associated with the jth candidate aperture value and the ith candidate focal length, the computer device calculates the virtual aperture value and the virtual focus value corresponding to the kth candidate focus value associated with the jth candidate aperture value and the ith candidate focal length, the virtual aperture value and the virtual focus value corresponding to the kth candidate focus value associated with the jth+1 candidate aperture value and the ith candidate focal length, the virtual aperture value and the virtual focus value corresponding to the kth candidate focus value associated with the jth candidate aperture value and the ith+1 candidate focal length, and the virtual aperture value and the virtual focus value corresponding to the kth candidate focus value associated with the jth+1 candidate aperture value and the ith+1 candidate focal length. The scene aperture value and the scene focus value of the target virtual scene are calculated. Specifically, please refer to Table 1 above, the ith candidate focal length of the reference camera device is A i , the ith+1 candidate focal length is A i+1 , the jth candidate aperture value is B j , the jth+1 candidate aperture value is B j+1 , and the kth candidate focus value is C k .

[0162] In a specific implementation, assuming that the actual focus value of the target camera device is FS3, and the actual aperture value is Q3, the computer device determines, based on A i , B j and C k , the scene aperture value of the virtual scene corresponding thereto from Table 1 is T k , and the scene focus value is W k ; based on A i , B j+1 (assuming that B j+1 > B j ) and C k , the scene aperture value of the virtual scene corresponding thereto from Table 1 is U k (assuming that U k > W k ), and the scene focus value is V k ; based on A i+1 , B j and C k , the scene aperture value of the virtual scene corresponding thereto from Table 1 is HA k , and the scene focus value is HB k ; based on A i+1 , B j+1 and C k , the scene aperture value of the virtual scene corresponding thereto from Table 1 is GA k (assuming that GA k > HAk ), the scene focal point value is GB k ; the specific corresponding relationship is shown in Table 4:
