[0049] Typical embodiments that embody the features and advantages of the present disclosure will be described in detail in the following description. It should be understood that the present disclosure can have various variations in different embodiments without departing from the scope of the present disclosure, and the descriptions and illustrations therein are essentially for illustrative purposes and not for limiting the present disclosure.

These descriptions are appropriate when these elements are in the positions shown in the drawings. If the descriptions of the positions of these elements change, the indications of these directions will also change accordingly.

[0051] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be understood to indicate or imply relative importance or implicitly specify the number of the technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the described features. In the description of this application, "plurality" means two or more, unless otherwise specifically defined.

[0052] Referring to Figure 1, Figure 1 is a structural block diagram of the lighting control system provided in an embodiment of the present application. As shown in Figure 1, the lighting control system includes a control device 100 and multiple lighting devices 200. Among them, the control device 100 is connected to the lighting device 200, so that the control device can control the light emission of the lighting device 200. Specifically, the control device 100 and the lighting device 200 can be connected wirelessly or by wire. For example, the control device 100 can be connected to the lighting device 200 via Bluetooth or CRMX (Cognitive Radio Multiplexer, a radio frequency multiplexer with cognitive function), or the control device 100 can be connected to the lighting device 200 by wire via Ethernet. Exemplarily, the control device 100 can establish a connection with the lighting device 200 via a wireless DMX (Digital Multiple X, multiplexed digital transmission) transceiver with Bluetooth function. The control device 100 can be a terminal device such as a mobile phone, tablet computer, PC, etc. The control device 100 is installed with executable light control software. The control device 100 can configure and control the lighting device 200 by running the light control software. For example, the control device 100 can adjust the lighting parameters of the lighting device 200, such as brightness, hue, color, saturation and color temperature, by running the light control software.

[0053] In one embodiment of the present application, referring to FIG. 1 , the lighting control system further includes a display device 300 connected to the control device 100 and configured to display a background video. The display device 300 and the control device 100 can be connected wirelessly or wired. Specifically, by importing pre-edited video material into the control device 100, the control device 100 can control the display device 300 to display the corresponding background video. In this case, by running lighting control software on the control device 100, the lighting devices 200 can be configured within the corresponding control interface. Locations in the background video can be mapped to lighting devices 200 at the filming site. Mapping points associated with each lighting device 200 at the filming site can then be selected from the background video. Each mapping point is associated with a group of lighting devices 200. A group of lighting devices can be a single lighting device or multiple lighting devices installed in the same area at the filming site. Thus, by acquiring the color parameters of each mapping point in the background video and transmitting them to the lighting device 200 associated with the mapping point, the lighting of the lighting device 200 can be adjusted in accordance with the background video. You can use on-site lighting equipment to simulate the lighting effects in the video background, allowing the subject to blend more seamlessly into the overall video background to create a more realistic visual effect.

[0054] In one embodiment of the present application, referring to FIG. 1 , the control device 100 includes a camera 110 for capturing background video. The camera 110 can be a camera. The control device 100 is equipped with the camera 110, allowing the camera 110 to be aimed at the virtual scene being played to capture the video background in real time. Similarly, by running lighting control software on the control device 100 and configuring the lighting devices 200 on the corresponding control interface, mapping locations in the background video to the lighting devices 200 at the filming site is specified. This means that mapping points associated with each lighting device 200 at the filming site are selected in the background video, with each mapping point corresponding to a group of lighting devices 200. Thus, by capturing the video background in real time, the color parameters of each mapping point in the background video can be obtained in real time and sent to the lighting device 200 associated with the mapping point, allowing the lighting of the lighting device 200 to be adjusted in real time based on the background video.

[0055] In the embodiment of the present application, by running the light control software on the control device 100, the lighting device 200 can be configured and its parameters adjusted. By capturing a video background and setting the lighting device 200 to simulate the lighting effects in the background video, the lighting of the lighting device 200 can be adjusted in real time with the video background, so that the on-site lighting matches the virtual scene.

[0056] In today's video shooting scenarios, multiple video lights are often deployed on set to meet lighting requirements. However, existing video lights are all controlled centrally through a console. When there are a large number of video lights, users cannot quickly associate each light with its corresponding control button. Consequently, every time a light adjustment is needed, users must first search for the correct one. This operation is very cumbersome and cannot meet the fast pace of filming.

[0057] Based on this, the embodiment of the present application proposes a lighting visualization management method. Through the visual management of lighting equipment, when it is necessary to adjust and control the lighting equipment at the shooting site, the corresponding lighting icon can be intuitively found and controlled. The operation is simple and can well meet the fast working pace of the shooting site.

[0058] 2 , which is a flowchart of the steps of the lighting visualization management method provided in an embodiment of the present application, is executed by the control device 100 in the lighting control system proposed in any embodiment of the present application, including but not limited to steps S210 to S240 .

[0059] Step S210: establishing a communication connection with each lighting device at the shooting scene.

[0060] In the embodiment of the present application, a communication connection is first established between the control device 100 and the lighting device 200. Specifically, the control device 100 and the lighting device 200 can be connected wirelessly or by wire. For example, the control device 100 can be connected to the lighting device 200 via Bluetooth or DMX, or the control device 100 can be connected to the lighting device 200 by wire via Ethernet. For example, the control device 100 can establish a connection with the lighting device 200 via a wireless DMX transceiver with Bluetooth functionality. The control device 100 can be a terminal device such as a mobile phone, tablet computer, or PC. The control device 100 is installed with executable lighting control software. By running this lighting control software, the control device 100 can achieve visual management of the lighting device 200.

[0061] Step S220: Obtain basic information of the lighting equipment and generate a corresponding lighting icon.

[0062] In the embodiment of the present application, the control device 100, by running the lighting control software, can enter basic information about each lighting device, such as the lighting type, model, and location at the filming location, into the corresponding control interface. After entering the basic information about the lighting device, a corresponding light icon can be generated based on the basic information. For example, if the lighting device entered is a panel light, a rectangular light icon corresponding to the panel light can be generated. If the lighting device entered is a flashlight, a circular light icon corresponding to the flashlight can be generated.

[0063] 3 , which is a flowchart of the steps for obtaining basic information of a lighting device and generating a corresponding lighting icon provided by an embodiment of the present application, including but not limited to steps S310 to S330 .

[0064] Step S310, obtaining basic information of the lighting equipment, including the lighting type and model of the lighting equipment;

[0065] Step S320: According to the light type, calling a preset light icon corresponding to the light type;

[0066] Step S330: Associating the light icon with the light device so that the light icon corresponds to the light device one-to-one.

[0067] In an embodiment of the present application, by pre-setting icons of different shapes corresponding to different types of lighting equipment, the pre-set light icons corresponding to the light types can be directly called after obtaining the light type of the lighting equipment. For example, it is pre-set that light type A corresponds to a rectangular light icon, light type B corresponds to a circular light icon, and light type C corresponds to a triangular light icon. Therefore, when the light type of the lighting equipment is identified as light type A, the rectangular light icon can be directly called out, and an association relationship between the rectangular light icon and the lighting equipment of light type A is established. When the light type of the lighting equipment is identified as light type B, the circular light icon can be directly called out, and an association relationship between the circular light icon and the lighting equipment of light type B is established. When the light type of the lighting equipment is identified as light type C, the triangular light icon can be directly called out, and an association relationship between the triangular light icon and the lighting equipment of light type C is established. In this way, the light icons and lighting equipment can be in one-to-one correspondence.

[0068] In one embodiment of the present application, after calling a preset light icon corresponding to the light type according to the light type, the method further includes:

[0069] Enter the light type information in the light icon and number the light icons.

[0070] In an embodiment of the present application, considering that a filming scene may contain multiple lighting devices with the same lighting type but different lighting models, to distinguish between these devices, the lighting type information can be entered in the light icons and the light icons can be numbered. For example, there are three lighting devices: a first lighting device, a second lighting device, and a third lighting device. They all have the same lighting type, lighting type A. In this case, the rectangular light icon corresponding to the first lighting device can be entered with the lighting type A and numbered ①. The rectangular light icon corresponding to the second lighting device can be entered with the lighting type A and numbered ②. The rectangular light icon corresponding to the third lighting device can be entered with the lighting type A and numbered ③. This allows for differentiating between lighting devices of the same lighting type. Furthermore, by entering the lighting type information in the light icons, it is also easier to identify lighting devices of the same lighting type through text, making it easier to subsequently search for and control lighting devices of the same lighting type.

[0071] In one embodiment of the present application, the location information of the corresponding lighting device at the shooting scene can also be recorded in the light icon. For example, if the first lighting device is located above the subject at the shooting scene, the location of the corresponding lighting device can be recorded as "above" in the light icon corresponding to the first lighting device. In this way, the correspondence between the light icon and the lighting device can be determined based on the location information of the corresponding lighting device marked in the light icon.

[0072] Step S230 , arranging the light icons in a preset grid diagram according to the light positions of the various light devices at the shooting scene, so that the positions of the light icons in the grid diagram correspond one-to-one to the light positions of the corresponding light devices at the shooting scene.

[0073] In the embodiment of the present application, the control device 100 can enter the corresponding light icons of each lighting device at the shooting scene in the corresponding control interface by running the light control software, so that each light icon on the control interface has a corresponding light device. The light control software can pre-store grid diagrams of various specifications (such as: 3*3, 3*4, 4*5, etc.), so that according to the light position layout of each lighting device at the shooting scene, a corresponding grid diagram can be generated on the corresponding control interface or adjusted to a preset corresponding grid diagram. Alternatively, a corresponding grid diagram can be generated according to the user's settings, such as first generating a grid diagram of specified specifications, and then dividing the shooting scene into areas corresponding to the grid diagram. At this time, the light icons are further arranged in a corresponding grid according to the light position layout of each lighting device at the shooting scene, so that the positions of the light icons in the grid diagram correspond one-to-one to the light positions of the corresponding lighting devices at the shooting scene.

[0074] For example, refer to Figure 4, which is an example diagram of the layout of light icons in a grid diagram provided by an embodiment of the present application. Since there is a panel light a1 and a2 on the left and right sides of the subject in the shooting scene, the light icons corresponding to the panel lights a1 and a2 need to be placed in the grids on the left and right sides of the middle (the position of the subject is in the middle position). There is a flash light b2 in front of the left of the subject, and the light icon corresponding to the flash light b2 needs to be placed in the grid in front of the left of the middle position. There is a flash light b3 in front of the right of the subject, and the light icon corresponding to the flash light b3 needs to be placed in the grid in front of the right of the middle position. There is a flash light b1 behind the subject, and the light icon corresponding to the flash light b1 needs to be placed in the grid behind the middle position. There is an auxiliary light c1 behind the left of the subject, and the light icon corresponding to the auxiliary light c1 needs to be placed in the grid in the rear left of the middle position. If there is an auxiliary light C2 behind the subject, the light icon corresponding to the auxiliary light C2 should be placed in the grid at the right rear of the center position. This ensures that the positions of the light icons in the grid map correspond to the positions of the lighting equipment at the shooting scene.

[0075] In an embodiment of the present application, by moving the position of each light icon in the grid map in the generated grid map interface so that it corresponds to the position of the lighting equipment corresponding to the shooting scene, the position of each light icon in the grid map can be made to correspond one-to-one with the light position of each lighting equipment at the shooting scene, so that the lighting equipment information at the shooting scene can be clear at a glance. When it is necessary to adjust and control the lighting equipment at the shooting scene, the corresponding light icon can be intuitively found and controlled.

[0076] Step S240 , triggering the light icon that needs to be adjusted in the grid diagram to input corresponding control parameters, and transmitting the control parameters to the corresponding lighting device, so that the lighting device emits light according to the received control parameters.

[0077] In this embodiment of the present application, by triggering the light image to be adjusted in the grid diagram, control parameters for controlling the corresponding lighting device can be input. Once input, due to the communication connection between the control device 100 and the lighting device 200, the control parameters can be directly transmitted to the corresponding lighting device to control the lighting of the corresponding lighting device. The control parameters are used to control the lighting parameters of the lighting device, including brightness, hue, color temperature, and saturation. For example, the input control parameters can control the overall brightness of the lighting device.

[0078] In one embodiment of the present application, triggering the light icon that needs to be adjusted in the grid diagram to input the corresponding control parameters includes:

[0079] Trigger the individual light icon that needs to be adjusted in the grid diagram to input the control parameters of the lighting device corresponding to the individual light icon;

[0080] Alternatively, multiple light icons that need to be adjusted in the grid diagram are triggered in sequence, so as to simultaneously input control parameters for the light devices corresponding to the multiple light icons.

[0081] In this embodiment of the present application, when adjusting and controlling individual lighting devices in a filming scene, the lighting parameters of each lighting device can be adjusted individually by triggering its corresponding lighting icon and entering the corresponding control parameters. For lighting devices of the same type, multiple lighting icons corresponding to the same lighting device can be triggered sequentially to simultaneously enter the control parameters for each lighting device of the same type, thereby improving adjustment efficiency. For example, a filming scene includes lighting device a1, lighting device a2, lighting device b1, lighting device b2, lighting device b3, lighting device c1, and lighting device c2. In this case, the lighting icon corresponding to lighting device a1 can be triggered first, and the corresponding control parameters can be entered to adjust the lighting parameters of lighting device a1. Then, the lighting icon corresponding to lighting device a2 can be triggered, and the corresponding control parameters can be entered to adjust the lighting parameters of lighting device a2. Finally, the lighting icon corresponding to lighting device b1 can be triggered, and the corresponding control parameters can be entered to adjust the lighting parameters of lighting device b1. Then, trigger the light icon corresponding to lighting device b2 and enter the corresponding control parameters to adjust the lighting parameters of lighting device b2. Then, trigger the light icon corresponding to lighting device b3 and enter the corresponding control parameters to adjust the lighting parameters of lighting device b3. Then, trigger the light icon corresponding to lighting device c1 and enter the corresponding control parameters to adjust the lighting parameters of lighting device c1. Then, trigger the light icon corresponding to lighting device c2 and enter the corresponding control parameters to adjust the lighting parameters of lighting device c2. In this way, each lighting device at the shooting scene can be adjusted one by one. Alternatively, since lighting devices a1 and a2 have the same lighting type, lighting devices b1, b2, and b3 have the same lighting type, and lighting devices c1 and c2 have the same lighting type, the light icon corresponding to lighting device a1 and the light icon corresponding to lighting device a2 can be triggered simultaneously, and the corresponding control parameters can be entered to adjust lighting devices a1 and a2 simultaneously. Simultaneously trigger the lighting icons for lighting device b1, lighting device b2, and lighting device b3, and enter the corresponding control parameters to adjust lighting devices b1, b2, and b3 simultaneously. Simultaneously trigger the lighting icons for lighting device c1 and lighting device c2, and enter the corresponding control parameters to adjust lighting devices c1 and c2 simultaneously. This allows lighting devices of the same type to be adjusted simultaneously, improving dimming efficiency.

[0082] In one embodiment of the present application, when a light icon that needs to be adjusted in a grid map is triggered, the method includes:

[0083] In response to the triggering operation of the light icon, the light device corresponding to the light icon is controlled to respond in a lighting or flashing manner.

[0084] In the embodiment of the present application, after a light icon is triggered, the light device corresponding to the light icon will light up or flash. Therefore, by triggering the light icon and observing the light device that lights up or flashes, the light device corresponding to the triggered light device can be determined. Therefore, if it is not clear which light icon corresponds to which light device image in the shooting scene, it can be determined by triggering the light icon and observing the light device that lights up or flashes.

[0085] In the embodiment of the present application, by triggering the light icon that needs to be adjusted in the grid diagram, the corresponding control parameters can be input to control the lighting of the corresponding lighting device. That is, by generating light icons corresponding to the lighting devices and arranging the positions of the light icons to correspond one-to-one with the lighting positions of the corresponding lighting devices at the shooting scene, the lighting equipment information at the shooting scene can be clearly seen. When the lighting equipment at the shooting scene needs to be adjusted or controlled, the corresponding light icon can be intuitively found and controlled. The operation is simple and can well meet the fast working pace of the shooting scene.

[0086] Nowadays, the demand for virtual production is increasing. If you want to capture a realistic sense of presence, it is extremely important to match the on-site lighting with the virtual scene.

[0087] However, during the process of combining virtual and real shooting, since the lighting equipment cannot automatically adjust according to the color parameters of the video background, the lighting effect on the person being photographed is quite different from that in the video background, and the realism of the shot video is poor.

[0088] Based on this, an embodiment of the present application proposes a lighting control method, which maps lighting equipment to corresponding mapping points in the video background one by one, so that the lighting equipment can emit light accordingly according to the color parameters of the corresponding mapping points in the video background, thereby reducing the difference between the light effect on the photographed person and the video background, and greatly improving the realism of the video.

[0089] 5 , which is a flowchart of a lighting control method provided in an embodiment of the present application, is executed by the control device 100 in the lighting control system provided in any embodiment of the present application, including but not limited to steps S510 to S530 .

[0090] Step S510: Obtain background video.

[0091] In the embodiment of the present application, light control software is run in the control device 100, and a background video is input into the light control software. The specific background video can be imported through the software, or the background video can be obtained in real time on site through the camera on the control device 100.

[0092] In one embodiment of the present application, a background video may be obtained by importing a video file into the control device 100 or by using the camera device 110 to collect and process background image information displayed at the shooting scene in real time.

[0093] For example, a pre-edited background video can be directly imported into the control device 100. The pre-edited background video can also be displayed and played by the display device, and the camera of the control device 100 is aimed at the screen of the display device playing the background video to obtain the background video.

[0094] Step S520 : Select mapping points associated with various lighting devices at the shooting scene in the background video, wherein one mapping point is associated with a group of lighting devices.

[0095] In an embodiment of the present application, after obtaining the background video, mapping points associated with various lighting devices at the shooting scene can be selected in the background video, that is, a mapping point is selected in the background video and associated with a lighting device at the shooting scene, so that the lighting device can simulate the light changes at the mapping point in the background video.

[0096] Specifically, the lighting equipment at the shooting location is first added to the control device 100. From there, users can select each mapping point in the background video and associate a corresponding lighting device with each mapping point. This means that each mapping point in the background video has a corresponding lighting device to simulate the lighting changes.

[0097] For example, lighting equipment is typically placed above, in front of, to the left, or to the right of the subject at a filming location. Before selecting a mapping point, the lighting equipment to be mapped (e.g., the upper light) is first selected and added to the control device 100. The mapping point to which the lighting equipment (e.g., the upper light) is to be mapped is then selected in the background video (e.g., the upper portion of the background video), and the mapping point is associated with the selected lighting equipment. During operation, the lighting equipment at each location is selected in sequence. After the lighting equipment is selected, the location to be mapped is triggered from the background video. The triggered location becomes the mapping point; there is a one-to-one correspondence between the lighting equipment and the mapping point.

[0098] 6 , which is a flowchart of the steps of selecting mapping points associated with various lighting devices at a shooting scene in a background video according to an embodiment of the present application, including but not limited to steps S610 to S620 .

[0099] Step S610: Select target lighting equipment that needs to be associated with the shooting scene.

[0100] Step S620 : Based on the position of the target lighting device at the shooting scene, a target mapping point corresponding to the target lighting device is selected at a corresponding position in the background video, and the target lighting device is associated with the target mapping point.

[0101] In the embodiment of the present application, by running the control interface corresponding to the light control software on the control device 100, the target lighting device to be associated with the shooting scene is first selected. Then, based on the location of the target lighting device at the shooting scene, a target mapping point corresponding to the target lighting device is selected at the corresponding location in the background video. For example, if the target lighting device is located above the subject at the shooting scene, a point is correspondingly selected at the upper portion of the image area of ​​the background video as the target mapping point for the target lighting device. In this way, the target lighting device can be associated with the target mapping point, so that each mapping point in the background video has a corresponding mapped lighting device. Thus, the lighting device at the shooting scene can be used to simulate the light changes at the corresponding mapping point in the background video.

[0102] For example, lighting devices 1, 2, 3, and 4 are positioned above, in front of, to the left, and right of a subject at a filming location. Lighting devices 1, 2, 3, and 4 are first connected to control device 100 and added to the corresponding control interface of control device 100. Then, select lighting device 1 and a point in the upper portion of the background video as mapping point A to associate lighting device 1 with mapping point A. Select lighting device 2 and a point in the front portion of the background video as mapping point B to associate lighting device 2 with mapping point B. Select lighting device 3 and a point in the left portion of the background video as mapping point C to associate lighting device 3 with mapping point C. Select lighting device 4 and a point in the right portion of the background video as mapping point D to associate lighting device 4 with mapping point D. In this way, each mapping point in the background video can be mapped and associated with its corresponding lighting device.

[0103] In one embodiment of the present application, after selecting mapping points associated with various lighting devices at the shooting scene in the background video, the method further includes:

[0104] The size of the image area corresponding to the mapping point in the background video is adjusted.

[0105] In the embodiment of the present application, the size of the image area corresponding to the mapping point in the background video is adjustable, thereby adjusting the color recognition accuracy. By increasing the image area corresponding to the mapping point in the background video, the color recognition accuracy can be improved. By decreasing the image area corresponding to the mapping point in the background video, the color recognition accuracy can be reduced.

[0106] Correspondingly, the control device 100 can also adjust the overall brightness of the lighting device so that the light of the lighting device can more accurately match the picture of the background video.

[0107] Step S530: obtaining the real-time color parameters of each mapping point in the background video and sending them to the lighting device associated with the mapping point, so that the lighting device emits light accordingly according to the color parameters.

[0108] In the embodiment of the present application, after selecting mapping points associated with various lighting devices at the shooting scene in the background video, the control device 100 obtains the real-time color parameters of each mapping point in the background video and transmits the color parameters of each mapping point to the lighting device associated with the mapping point. This enables the lighting device to emit light according to the color parameters of the corresponding mapping point, thereby simulating the color changes of the corresponding mapping point in the background video and recreating the light changes at the mapping point in the background video on the scene. Moreover, since the color of each mapping point in the background video changes in real time, the corresponding lighting device can adjust the light emitted in real time according to the changes in the background video, thereby reducing the difference between the lighting effect on the subject and the background of the video, and improving the realism of the captured video.

[0109] 7 , which is a flowchart of the steps for obtaining real-time color parameters of each mapping point in a background video provided by an embodiment of the present application, including but not limited to steps S710 to S730 .

[0110] Step S710, obtaining the image area corresponding to the mapping point in the background video;

[0111] Step S720, obtaining the color parameters of each pixel in the image area;

[0112] Step S730 , averaging the color parameters of all pixels in the image area to obtain the color parameters of the mapping point.

[0113] In an embodiment of the present application, by obtaining the image area corresponding to the mapping point in the background video and obtaining the color parameters of each pixel in the image area, the color parameters of each mapping point in the background video can be calculated. Specifically, by averaging the color parameters of all pixels in the image area corresponding to the mapping point in the background video, the color parameters of the mapping point can be obtained. Thus, by sending the real-time color parameters of the mapping point to the corresponding lighting equipment, the corresponding lighting equipment can make corresponding real-time adjustments to the luminous parameters of the lighting equipment according to the color parameters of the mapping point, so that the light emitted by the lighting equipment can match the picture in the background video. Among them, the color parameters can be expressed in one of the RGB (red, green, blue) color space, CMYK (cyan, magenta, yellow, black) color space, and HSV (hue, saturation, brightness) color space.

[0114] In this embodiment, since the real-time color parameters of each mapping point are captured, the lighting parameters of the lighting device are automatically adjusted based on changes in the real-time color parameters of the mapping point, ensuring that they always match the background video. For example, if lightning suddenly appears in the sky area of ​​the background video, the lighting device mapped above it will also flash accordingly, simulating the lighting effect in the background video.

[0115] 8 , which is another flow chart of a lighting control method provided in an embodiment of the present application, is executed by the lighting device 200 in the lighting control system provided in any embodiment of the present application, including but not limited to steps S810 to S820 .

[0116] Step S810, receiving the real-time color parameters of the corresponding mapping points sent by the control device;

[0117] Step S820: adjusting the light emission parameters according to the real-time color parameters of the corresponding mapping points so that the emitted light matches the image in the background video.

[0118] In the embodiments of the present application, the executing entity is the lighting device 200 in the lighting control system provided in any embodiment of the present application. The lighting device 200 receives the real-time color parameters of the corresponding mapping points sent by the control device 100. Thus, the lighting device 200 can adjust the lighting parameters accordingly based on the real-time color parameters of the corresponding mapping points, so that the emitted light matches the image in the background video. This can reduce the difference between the light effect on the subject and the background of the video, thereby improving the realism of the captured video.
