In addition, the character " / " in this article, unless otherwise specified, generally means that the associated objects before and after are in an "or" relationship.

[0066] The present application embodiment provides a light switching method, such as Figure 1 As shown, the method provided in the embodiment of the present application is executed by an electronic device, which can be a server or a terminal device, wherein the server can be an independent physical server, or a server cluster or distributed system composed of multiple physical servers, or a cloud server providing cloud computing services. The terminal device can be a smart phone, a tablet computer, a laptop computer, a desktop computer, etc., but is not limited thereto. The terminal device and the server can be directly or indirectly connected via wired or wireless communication, which is not limited in the embodiment of the present application. The method includes steps S101 to S104, wherein:

[0067] S101: Obtain a shooting plan.

[0068] In this embodiment, the shooting plan may be a script corresponding to a storyboard, and the script may include information such as time, location, characters, and events. The shooting plan may be manually uploaded to the electronic device.

[0069] S102: According to the shooting plan, determine the target scene and target light corresponding to the shooting plan.

[0070] In this embodiment, the shooting plan can be subjected to text analysis, and the scene type (such as a coffee shop, classroom, street, etc.), emotional atmosphere (happy, sad, peaceful, etc.) and shooting time period (morning, noon, evening, night, etc.) corresponding to the shooting plan can be obtained. According to the results of the text analysis, the target scene and target light corresponding to the shooting plan can be determined. The target scene is a preset scene corresponding to the scene type of the shooting plan, and the target light is the light that meets the emotional atmosphere and shooting time period of the shooting plan, including the light type, light tone and light intensity. Among them, the light type can include point light source, spotlight, directional light, ambient light, etc., and the light tone can include cool tones and warm tones. Cool tones can create a warm and comfortable atmosphere, and cool tones can create a calm and fresh feeling.

[0071] S103: Generate a virtual three-dimensional scene corresponding to the shooting plan according to the target scene and the target light.

[0072] In this embodiment, a corresponding virtual three-dimensional scene can be constructed using three-dimensional modeling software, such as Blender and Maya, according to the scene type of the target scene, and the light type, light tone, and light intensity of the target light.

[0073] S104, mapping the virtual three-dimensional scene to the target LED screen, and using the LED screen as a shooting background to complete the shooting.

[0074] Specifically, a rendering engine, such as Unity or Unreal Engine, can be used to render the virtual three-dimensional scene into a video stream and send it to a target LED screen. The target LED screen is set at the real shooting scene to display the video stream and serve as a shooting background, providing a shooting scene corresponding to the shooting plan.

[0075] The embodiment of the present application obtains a shooting plan, which includes shooting content, scenes and other information related to the shooting. According to the shooting plan, the target scene and target lighting corresponding to the shooting plan can be determined, so that the determined target lighting can conform to the shooting plan and the target scene. According to the target scene and the target lighting, the virtual three-dimensional scene corresponding to the shooting plan can be determined, and the obtained virtual three-dimensional scene is mapped on the target LED screen. The target LED screen serves as the shooting background. Since the LED screen provides a background and lighting effects that match the target scene, the shooting task can be completed more efficiently, reducing the adjustments and preparations required in the actual scene, realizing pre-planning and accurate simulation of the target scene and lighting, and improving the efficiency and effect of shooting.

[0076] In a possible implementation of the embodiment of the present application, the target light includes light type, light hue and light intensity.

[0077] Determine the target lighting for your shooting plan based on the scene type, emotional atmosphere, and shooting time, including:

[0078] Determine whether the scene type is indoors or outdoors, and obtain a determination result;

[0079] Determine the light type according to the first determination result, the shooting time period and a preset corresponding relationship, where the preset corresponding relationship is a corresponding relationship between the determination result, the shooting time period and the light type;

[0080] Determine the light tone and intensity based on the emotional atmosphere and shooting time.

[0081] In this embodiment, natural language technology can be used to perform text analysis on the shooting plan. Specifically, the text in the shooting plan can be segmented first, and each word in the shooting plan can be separated separately; then part-of-speech tagging is performed, and each word after the segmentation is tagged with part-of-speech to determine its semantic type. For example, "cafe" can be tagged as a noun, and "happy" can be tagged as an adjective; then, keywords of scene type, emotional atmosphere and shooting time period can be extracted from the text after part-of-speech tagged by keyword extraction algorithms, such as TF-IDF (term frequency-inverse document frequency) or TextRank algorithm; further, classification algorithms, such as naive Bayes classifier, support vector machine, etc., can be used to classify the obtained keywords to obtain keywords corresponding to the scene type, emotional atmosphere and shooting time period.

[0082] Furthermore, after determining the scene type, emotional atmosphere and shooting time period corresponding to the shooting plan, the lighting type can be determined according to whether the location corresponding to the scene type is indoors or outdoors, and the shooting time period, and the lighting tone and lighting intensity can be determined according to the emotional atmosphere and shooting time period.

[0083] The embodiments of the present application can quickly and accurately identify and understand key information in the shooting plan by performing text analysis on the shooting plan, thereby improving the efficiency of decision-making and preparation. In combination with the preset scene library, the target scene can be quickly determined, reducing the time for searching and selecting. The target lighting is generated according to multi-dimensional information, which can ensure that the lighting effect matches the shooting plan and the target scene, providing a better background and atmosphere for shooting, reducing errors and omissions caused by human factors, and improving the accuracy and quality of shooting work.

[0084] In a possible implementation of the embodiment of the present application, the target light includes light type, light hue and light intensity.

[0085] Determine the target lighting for your shooting plan based on the scene type, emotional atmosphere, and shooting time, including:

[0086] Determine whether the scene type is indoors or outdoors, and obtain a determination result;

[0087] Determine the light type according to the first determination result, the shooting time period and a preset corresponding relationship, where the preset corresponding relationship is a corresponding relationship between the determination result, the shooting time period and the light type;

[0088] Determine the light tone and intensity based on the emotional atmosphere and shooting time.

[0089] In this embodiment, each scene type may be marked in advance, and the marked content may include indoor or outdoor. According to the marked content of the scene type corresponding to the shooting plan, a determination result may be obtained to determine whether the scene type is indoors or outdoors.

[0090] Further, a preset correspondence can be set. Optionally, a point light source or a spotlight can be used indoors and at noon. A point light source usually simulates the light emitted by a light bulb, and its light intensity decreases from the center to the surroundings. A spotlight is a light source with a clear light beam. The indoor light is strong during the noon period. The use of a point light source or a spotlight can simulate natural light and provide sufficient lighting for the scene. A yellow light can be used indoors and in the evening. The light emitted by a yellow light is yellowish in color and has a lower color temperature, giving people a warm feeling. In the evening, a yellow light can simulate the light of dusk. Directional light can be used outdoors and at noon. Directional light is a light source with a clear irradiation direction that can simulate the effect of sunlight and provide a strong lighting and shadow effect for the scene. The specific correspondence between the determination result, the shooting period, and the light type can be set according to actual experience, and this embodiment does not make specific limitations.

[0091] By judging the scene type, the embodiment of the present application can provide basic guidance for subsequent lighting selection. By using preset correspondences, the appropriate lighting type can be determined quickly and accurately, thereby improving decision-making efficiency. The lighting tone and intensity are determined according to the emotional atmosphere and shooting period, ensuring that the lighting effect matches the shooting requirements and emotional expression, thereby improving the quality and effect of the shooting.

[0092] In a possible implementation of the embodiment of the present application, the emotional atmosphere includes an emotional type and an emotional level.

[0093] Determine the lighting tone and intensity based on the emotional atmosphere and shooting time, including:

[0094] Determine the lighting tone according to the type of emotion;

[0095] Determine the initial light intensity based on the shooting period;

[0096] An adjustment coefficient corresponding to the emotion level is determined, and the initial light intensity is adjusted according to the adjustment coefficient to obtain the light intensity.

[0097] In this embodiment, emotion types may include happiness, sadness, and tension, and the correspondence between emotion types and light tones may be set based on actual experience. Optionally, the happy emotion type may be associated with warm-toned lights (such as red and orange), the sad emotion type may be associated with cool tones (such as blue and purple), and the nervous emotion type may be associated with neutral-toned lights (such as white). The correspondence between emotion types and light tones may be flexibly adjusted based on actual experience and needs, and this embodiment does not impose any specific limitations.

[0098] Furthermore, the initial light intensity corresponding to each shooting period can be determined based on the actual ambient light intensity. The actual ambient light intensity of each shooting period within a period of time can be collected, for example, the actual ambient light intensity corresponding to the morning, noon, afternoon and evening every day within a month, to obtain multiple actual ambient light intensities corresponding to each shooting period. The average light intensity of the multiple actual ambient light intensities corresponding to each shooting period can be calculated as the initial light intensity corresponding to the shooting period.

[0099] Furthermore, a corresponding adjustment coefficient may be determined for each emotion level, the emotion level includes the intensity of the emotion, the more intense the emotion, the higher the corresponding level, optionally, the emotion level may include level one, level two and level three, the adjustment coefficient corresponding to level one may be 80%, the adjustment coefficient corresponding to level two may be 100%, and the adjustment coefficient corresponding to level three may be 120%. The product of the initial light intensity and the adjustment coefficient may be used as the light intensity.

[0100] The embodiment of the present application determines the lighting tone according to the emotion type, ensuring the matching of the lighting tone with the emotional atmosphere and enhancing the expression of emotions. The initial lighting intensity is determined according to the shooting period to ensure the matching with the shooting period, providing a basis for subsequent adjustments. The adjustment coefficient is determined according to the emotion level, and the lighting intensity can be accurately adjusted to match the emotional atmosphere, ensuring the accuracy and effect of the lighting, and improving the quality of shooting and the audience experience.

[0101] In a possible implementation manner of the embodiment of the present application, the preset scene library includes multiple preset scenes and scene information corresponding to each preset scene, and the scene information includes a scene type and a scene description.

[0102] According to the scene type, determine the target scene from the preset scene library, including:

[0103] Determine a plurality of preset scenes matching the scene type from a preset scene library;

[0104] Determine the number of several preset scenarios;

[0105] If the number of the preset scenes is one, determining the preset scenes as the target scenes;

[0106] If the number of preset scenes is not one, the shooting plan is matched with the scene description corresponding to each preset scene in the preset scenes to obtain the matching degree corresponding to each preset scene in the preset scenes, and a preset scene with the highest matching degree is determined from the preset scenes as the target scene.

[0107] In this embodiment, the preset scene library contains one or more preset scenes corresponding to each scene type, each preset scene has a corresponding scene type and scene description, and by comparing the scene type corresponding to the shooting plan with the scene type in the preset scene library, a number of preset scenes matching the scene type can be determined. When the number of the preset scenes is not one, keywords can be identified and extracted from the shooting plan by natural language processing technology (such as NLP libraries such as spaCy or NLTK), the scene description of each preset scene in the preset scenes can be read, and keywords can be identified and extracted by natural language processing technology, and the keywords of the shooting plan and the keywords corresponding to each preset scene in the preset scenes can be matched to obtain a matching degree. The matching method can use a cosine similarity or a Jaccard similarity algorithm.

[0108] The embodiment of the present application ensures that the subsequently selected scenes are consistent with the requirements in the shooting plan by screening preset scenes that match the scene type. Different strategies are selected to determine the target scene based on the number of preset scenes, which can more accurately determine the target scene that best matches the shooting plan, thereby improving the accuracy and effect of the selection.

[0109] A possible implementation of the embodiment of the present application is to map the virtual three-dimensional scene to the target LED screen, including:

[0110] Get the display ratio of the target LED screen;

[0111] Render the virtual 3D scene into a video stream according to the display ratio and preset output resolution;

[0112] Send the video stream to the target LED screen.

[0113] In this embodiment, the display ratio of the target LED screen, such as 16:9 or 4:3, can be obtained through the communication interface of the target LED screen. The display ratio determines the aspect ratio of the virtual three-dimensional scene mapped to the target LED screen. The target LED screen can be composed of multiple LED screens, and the display resolution of the target LED screen is the sum of the resolutions of the multiple LED screens. The preset output resolution is the maximum output resolution that can be achieved for rendering the virtual three-dimensional scene. Sending the rendered video stream to the target LED screen can be achieved through a video transmission protocol (such as HDMI, VGA or DVI) to ensure that the video stream is not lost during the transmission process and can be mapped on the target LED screen in real time.

[0114] The embodiment of the present application ensures the accurate display of the virtual three-dimensional scene on the target LED screen by obtaining the display ratio of the target LED screen, renders the video stream according to the display ratio and the preset output resolution, ensures that the format and parameters of the video stream match the target LED screen, improves the accuracy and effect of the display, sends the video stream to the target LED screen, realizes the seamless connection between the virtual scene and the actual display device, and provides the audience with an immersive visual experience.

[0115] A possible implementation of the embodiment of the present application is to send a video stream to a target LED screen, including:

[0116] Get the display resolution of the target LED screen, and compare the preset output resolution with the display resolution;

[0117] If the preset output resolution is smaller than the display resolution, the pixel value of each point in each frame of the video stream is obtained;

[0118] According to the display resolution and the pixel value of each point in each frame of the video stream, pixel interpolation is performed on each frame of the video stream to obtain a video stream with a resolution matching the target LED screen.

[0119] In this embodiment, when the preset output resolution is equal to the display resolution of the target LED screen, the resolution of the video stream may not be adjusted, and the video stream may be directly output to the target LED screen. When the preset output resolution is greater than the display resolution of the target LED screen, it indicates that the preset output resolution exceeds the maximum supported resolution of the target LED screen, and the video stream may be scaled by the video processing software to adjust the resolution of the video stream to the resolution of the target LED screen. When the preset output resolution is less than the display resolution of the target LED screen, the resolution of the video stream is adjusted to be equal to the resolution of the target LED screen by pixel difference, and the optional pixel difference algorithms include bilinear interpolation, bicubic interpolation, nearest neighbor interpolation, etc.

[0120] The embodiment of the present application obtains the original pixel values ​​and interpolates them to obtain a higher resolution video stream, so that it matches the resolution of the target LED screen, ensuring the best display effect of the video stream on the LED screen and avoiding problems such as blurring, distortion or stretching caused by resolution mismatch.
