[0064]

[0065] In this embodiment, the virtual stage performance simulation data includes a virtual stage simulation script and audio-visual data, and step S102 includes:

[0066] Extracting corresponding virtual stage scenario metadata from the virtual stage simulation script;

[0067] Extracting corresponding virtual stage scenario metadata from the audio-visual data.

[0068] It should be noted that metadata parameter values related to the performance content can be automatically extracted from the virtual stage performance simulation data. Exemplarily, corresponding virtual stage scenario metadata can be retrieved and extracted from the virtual stage simulation script. It is also possible to analyze and extract corresponding virtual stage scenario metadata from the audio-visual data through technologies such as image recognition and voice recognition. In addition, virtual stage scenario metadata can also be manually input by stage simulation designers, which is not limited here.

[0069] Various types of virtual stage scenario metadata can be stored in the form of corresponding metadata tables. Exemplarily, please refer to Table 3, Table 4, and Table 5, which are the example tables of scene metadata, character metadata, and music metadata respectively.

[0070] Table 3. Example Table of Scene Metadata

[0071] Scene Number Performance Type Scene Environment Scene Atmosphere Scene 1 S1 Multi-person Dialogue Indoor in the Morning Angry Scene 2 S2 Multi-person Dance Outdoor at Dusk Cheerful Scene 3 S3 Single-person Singing Outdoor at Night Sad and Solemn

[0075] Music Number Belonging Scene Performance Type Music Style Music Rhythm Music 1 M1 S2 Dance Music Rock 60 Beats per Minute Music 2 M2 S3 Song Classical 30 Beats per Minute

[0076] As shown in Table 3, the example table of scene metadata includes the numbers of each scene, performance types, scene environments, and scene atmospheres. As shown in Table 4, the example table of character metadata includes the numbers of each character, the scenes to which the characters belong, the performance types of the characters, character emotions, etc. As shown in Table 5, the example table of music metadata includes the numbers of each piece of music, the scenes to which the music belongs, performance types, music styles, and music rhythms, etc.

[0077] Step S103, through a scenario lighting simulation algorithm, generate a stage lighting simulation plan based on the virtual stage scenario metadata and the stage lighting model parameters.

[0078] In this embodiment, the scenario lighting simulation algorithm is divided into a scene lighting simulation algorithm, a character lighting simulation algorithm, a music lighting simulation algorithm, etc.

[0079] Please refer to Figure 2 , step S103 includes:

[0080] Step S1031: Obtain multiple multi-dimensional scene metadata vectors according to the virtual stage scenario metadata through the scenario lighting simulation algorithm. Based on the historical lighting design data in different scenes, count the occurrence times of each parameter value of each attribute object of the virtual stage lighting model under each of the multi-dimensional scene metadata vectors. Generate a two-dimensional matrix of the virtual stage lighting model attribute objects and the multi-dimensional scene metadata vectors according to the occurrence times of each parameter value of each attribute object under each multi-dimensional scene metadata vector.

[0081] Step S1032: Compare the metadata vector of the current scenario with each multi-dimensional scene metadata vector of the two-dimensional matrix to obtain a target metadata vector that matches the metadata vector of the current scenario.

[0082] Step S1033: Determine the parameter value with the most occurrences among the attribute objects of the target metadata vector.

[0083] Step S1034: Generate a stage lighting simulation plan according to the parameter value with the most occurrences and the stage lighting model parameters.

[0084] In this embodiment, the scene lighting simulation algorithm realizes the following process: Combine the scene metadata (the scene metadata is all the metadata included in the scene object) into a multi-dimensional scene metadata vector. Referring to Table 2, the example table of scene metadata, the multi-dimensional scene metadata vector can be: (multiple people talking, indoor morning, angry), (multiple people talking, indoor morning, cheerful), (multiple people talking, indoor morning, solemn), (multiple people talking, outdoor dusk, angry), (multiple people talking, outdoor dusk, cheerful), (multiple people talking, outdoor dusk, solemn), (multiple people talking, outdoor night, angry), (multiple people talking, outdoor night, cheerful), (multiple people talking, outdoor night, solemn), (multiple people dancing, indoor morning, angry), (multiple people dancing, indoor morning, cheerful), (multiple people dancing, indoor morning, solemn), ……, (single person singing, outdoor night, solemn), etc., or other multi-dimensional scene metadata vectors, which are not limited here.

[0085] The scene lighting simulation algorithm also implements the following process: Based on the historical lighting design data in different scenes, it counts the occurrence times of different parameter values of different types of attribute objects in the virtual stage lighting model in each multi-dimensional scene metadata vector, and generates a two-dimensional matrix of the virtual stage lighting model attribute objects and the multi-dimensional scene metadata vectors. Please refer to Table 6 and Table 7. Table 6 is an example table of the two-dimensional matrix, and Table 7 is another example table of the two-dimensional matrix.

[0086] Table 6, an example table of the two-dimensional matrix

[0087]

[0088] Table 7, another example table of the two-dimensional matrix

[0089]

[0090]

[0091] As shown in Table 6, the lighting types include: spotlight, soft light, backlight, floodlight, footlight. According to the historical data, it counts the occurrence times of each type of lamp under each multi-dimensional scene metadata vector. For example, the spotlight appears 1099 times under the vector of (multi-person conversation, indoor morning, angry).

[0092] As shown in Table 7, the lighting colors include: red, white, orange, blue, green. The historical lighting design data counts the occurrence times of each color under each multi-dimensional scene metadata vector. For example, red appears 878 times under the vector of (multi-person conversation, indoor morning, angry). It should be noted that the implementation processes of the character lighting simulation algorithm and the music lighting simulation algorithm are similar to that of the scene lighting simulation algorithm. To avoid repetition, they will not be elaborated here.

[0093] In this embodiment, it can receive the current scene formulated by the stage designer, obtain the metadata vector of the current scene, compare the metadata vector of the current scene with the two-dimensional matrix, take the multi-dimensional scene metadata vector closest to the metadata vector of the current scene in the two-dimensional matrix as the target scene metadata vector, obtain the occurrence times of each parameter value of the model object corresponding to the target scene metadata vector, and generate a scenario lighting simulation plan according to the parameter value with the most occurrences and the virtual stage lighting model data. The scenario lighting simulation plan can include a scene lighting simulation plan, a character lighting simulation plan, and a music lighting simulation plan, and can realize the lighting simulation of various scenes. Exemplarily, refer to Table 8. Table 8 is an example table of the scene lighting simulation plan.

[0094] Table 8, an example table of the scene lighting simulation plan

[0095]

[0096]

[0097] For example, the scenario lighting simulation solution for Scenario 1 is a soft light, the light is in front of the stage, the light is orange, the brightness is 60W, and the lighting effect is frontal lighting. The scenario lighting simulation solutions for other scenarios can be obtained according to the actual matching situation and are not limited here.

[0098] In one embodiment, generating a stage lighting simulation solution based on the parameter value with the most occurrences and the stage lighting model parameters includes:

[0099] Generating at least two scenario lighting simulation solutions for the current scenario based on the parameter value with the most occurrences and the stage lighting model parameters;

[0100] Combining at least two of the scenario lighting simulation solutions according to a preset lighting simulation solution combination strategy to obtain the stage lighting simulation solution.

[0101] In this embodiment, at least two scenario lighting simulation solutions may include a scene lighting simulation solution, a character lighting simulation solution, and a music lighting simulation solution. Refer to Tables 9 - 11. Table 9 is another example table of the scene lighting simulation solution, Table 10 is an example table of the character lighting simulation solution, and Table 11 is an example table of the music lighting simulation solution.

[0103]

[0104] Table 10. An example table of the character lighting simulation solution

[0105]

[0106]

[0107] Table 11. An example table of the music lighting simulation solution

[0108]

[0109] In this embodiment, the scene lighting simulation solution, the character lighting simulation solution, and the music lighting simulation solution can be combined to generate a complete stage lighting simulation solution. It should be noted that if there are no conflicts among multiple lighting simulation solutions, the overall lighting simulation solution can be directly obtained by adding them. If there are conflicts among multiple lighting simulation solutions during the combination process, then based on the lighting simulation solution combination strategy, according to the weights of the lighting attribute objects in different performance types in each dimension, the parameter values of the conflicting attribute objects are eliminated, for example, eliminating the conflicting parameter values such as lighting effects, colors, and brightness.

[0110] In one embodiment, the preset lighting simulation scheme combination strategy includes a non-conflict combination strategy. Combining at least two scenario lighting simulation schemes according to the preset lighting simulation scheme combination strategy includes:

[0111] When the simulation objects of at least two scenario lighting simulation schemes are different and the simulation effects do not conflict, add at least two scenario lighting simulation schemes according to the non-conflict combination strategy to obtain a stage lighting simulation scheme.

[0112] In one embodiment, the preset lighting simulation scheme combination strategy includes a conflict combination strategy. Combining at least two of the scenario lighting simulation schemes according to the preset lighting simulation scheme combination strategy includes:

[0113] When at least two of the scenario lighting simulation schemes belong to the first conflict situation or the second conflict situation, determine the weights of each lighting simulation attribute object in at least two of the scenario lighting simulation schemes according to the conflict combination strategy;

[0114] Eliminate the conflicting attribute object parameter values according to the weights of each lighting simulation object to obtain a stage lighting simulation scheme;

[0115] Wherein, the first conflict situation is that the simulation attribute objects are the same and the attribute object parameter values conflict, and the second conflict situation is that the simulation attribute objects are different and the simulation effects conflict.

[0116] Exemplarily, determining the weights of each lighting simulation attribute object in at least two of the scenario lighting simulation schemes can be carried out according to the following principles:

[0117] Switch(performance type) {

[0118] Case solo: weight of music lighting simulation attribute object > weight of character lighting simulation attribute object > weight of scene lighting simulation attribute object

[0119] Case chorus: weight of character lighting simulation attribute object > weight of music lighting simulation attribute object > weight of scene lighting simulation attribute object

[0120] Case dance: weight of character lighting simulation attribute object > weight of music lighting simulation attribute object > weight of scene lighting simulation attribute object

[0121] Case multi-person dialogue: weight of scene lighting simulation attribute object > weight of character lighting simulation attribute object > weight of music lighting simulation attribute object

[0122] Case monologue: weight of character lighting simulation attribute object > weight of scene lighting simulation attribute object > weight of music lighting simulation attribute object.

[0123] For example, please refer to Table 12. For scenario 3 in Table 12, the performance type is "solo singing". The scenario lighting simulation attribute object adopts the "footlights + front light" scheme, and the music lighting simulation attribute object adopts the "footlights + balcony light" scheme. This belongs to the situation where the simulation attribute objects are the same, but the values of the simulation attribute objects are different. According to the policy "weight of music lighting simulation attribute object > weight of character lighting simulation attribute object > weight of scenario lighting simulation attribute object", the music lighting simulation attribute object, that is, the "footlights + balcony light" scheme, is retained. In this way, conflicts can be eliminated.

[0125]

[0126] Exemplarily, please refer to Table 13. Table 13 is an example table of stage lighting simulation scheme. The stage lighting simulation scheme includes character (actor 1), number (A1), lighting type (follow spot), lighting position (in front of the stage), lighting color (white), lighting brightness (50W), lighting effect (follow light), etc.

[0131] Exemplarily, the partial code for generating virtual stage lighting simulation parameters is as follows:

[0132]

[0133] In one implementation manner, step S104 includes:

[0134] Generate first lighting simulation parameters according to the stage lighting simulation scheme;

[0135] Extract the virtual stage performance object and its virtual performance data from the virtual stage performance simulation data, and convert the virtual performance data into second lighting simulation parameters;

[0136] Generate the virtual stage lighting simulation parameters according to the first lighting simulation parameters and the second lighting simulation parameters.

[0137] In this embodiment, the virtual actor object and its virtual performance data such as position and movement trajectory are identified from the virtual stage performance simulation data, and the virtual performance data is converted into the second lighting simulation parameters. The identification method can be to retrieve and analyze the virtual actor object and its virtual performance data from the virtual stage simulation script, or to analyze the virtual actor object and its virtual performance data from the audio-visual content through technologies such as image recognition and voice recognition.

[0138] Exemplarily, the following code can be used to retrieve and analyze the virtual actor object data in the virtual stage simulation script to obtain the trajectory data of the virtual actor.

[0139]

[0140]

[0141] In this embodiment, the follow spot simulation parameters are calculated by using the trajectory data of the identified virtual actor object, such as rotation coordinates, rotation angles, etc., and are merged with the previously generated follow spot simulation parameters to generate complete follow spot simulation parameters.

[0142] Exemplarily, the following code can be used to generate complete follow spot simulation parameters.

[0143]

[0144]

[0145] Step S105, generate the virtual stage lighting simulation effect according to the stage lighting model parameters, the lighting simulation data, the virtual stage lighting simulation parameters, and the virtual stage performance simulation data.

[0146] In this embodiment, the virtual stage lighting simulation script can be generated by using the virtual stage lighting simulation parameters, and the animation effect simulation of the stage lighting can be automatically completed based on the already generated virtual stage performance simulation data.

[0147] In one implementation manner, step S105 includes:

[0148] Generate a virtual stage lighting simulation script according to the stage lighting model parameters, the lighting simulation data, and the virtual stage lighting simulation parameters;

[0149] Generate the virtual stage lighting simulation effect according to the virtual stage lighting simulation script and the virtual stage performance simulation data.

[0150] In this way, the animation effect design and simulation of the stage lighting can be automatically completed according to the design requirements of the scene, characters, and music of the stage program, improving the lighting simulation efficiency.

[0151] The virtual stage lighting simulation method provided in this embodiment establishes different types of stage lighting model parameters and lighting simulation data according to the specification data of stage lighting equipment, automatically extracts virtual stage scenario metadata using virtual stage performance simulation data, generates a stage lighting simulation plan based on the stage scenario metadata and the stage lighting model parameters, automatically generates virtual stage lighting simulation parameters according to the virtual stage lighting simulation plan and the stage performance simulation data, and automatically completes the animation effect simulation of virtual stage lighting using the stage lighting model parameters, lighting simulation data, virtual stage lighting simulation parameters, and virtual stage performance simulation data. It can automatically complete the animation effect design and simulation of stage lighting according to the stage scenario design requirements such as the scene, characters, and music of the stage program, improving the lighting simulation efficiency and simulation effect.
