As for the structures, products, etc. disclosed in the embodiments, since they correspond to the parts disclosed in the embodiments, the description is relatively simple, and the relevant parts can be referred to the description of the method part.

[0047] like Figure 1 As shown, Figure 1 A flowchart of a lighting control method provided by an embodiment of the present invention. The lighting control method provided by an embodiment of the present invention can be executed by a lighting device, the lighting device includes a light source component, an information acquisition component, a motion component and a communication module, the information acquisition component is arranged on the light source component, the information acquisition component includes an image acquisition module and a spectrum sensor, the image acquisition module and the spectrum sensor are arranged coaxially, the motion component is used to drive the light source component to rotate, and the communication module is used to communicate with the terminal device. For example, Figure 2 As shown, Figure 2A schematic diagram of the structure of a lighting device provided by an embodiment of the present invention, Figure 2 In the figure, the light source assembly 11 of the lighting device includes a dimmable LED lamp, the motion assembly 12 uses a motor, the image acquisition module 13 uses a camera, and the camera and the probe of the spectral sensor 14 (such as a spectral confocal sensor) are coaxially installed, that is, their lenses or probes are located on the same axis. The motion assembly 12 can drive the light source assembly 11 to rotate clockwise or counterclockwise around a certain center of a circle, thereby driving the image acquisition module 13 and the spectral sensor 14 arranged on the light source assembly 11 to rotate around the circumference together, wherein the center of the circumference can be pre-set according to actual needs. In addition, the lighting device can be wirelessly connected to a terminal device such as a mobile phone or a tablet through the communication module 15, so that the lighting device and the terminal device can communicate with each other.

[0048] The lighting control method provided by the embodiment of the present invention includes:

[0049] Step 101: Receive object type information and dimming mode information sent by a terminal device through a communication module.

[0050] When the user needs to control the lighting device to illuminate an object, the user can select a lighting device on the terminal device and determine the type of object that the lighting device needs to illuminate (such as a round table, sofa, green plant or piano, etc.) and the dimming mode. After the terminal device generates object type information according to the object type and generates dimming mode information according to the dimming mode, the object type information and the dimming mode information are sent to the lighting device selected by the user. The lighting device receives the object type information and the dimming mode information sent by the terminal device through the communication module. Exemplarily, an APP for controlling the lighting device is installed on the terminal device, and a map of the environmental space where the lighting device is located is displayed on the graphical interface of the APP. The map displays each lighting device and the location of each lighting device, such as Figure 3 As shown, Figure 3 This is a schematic diagram of a map provided by an embodiment of the present invention. In the figure, L1 to L8 are all lighting devices. The location of each lighting device can be marked and entered into the map when it is installed. When a user needs to control a lighting device to illuminate an object, the user can select a lighting device or multiple lighting devices to be controlled on the map. After the selection is completed, an object type input box and a dimming mode selection option will pop up on the graphical interface of the terminal device, such as Figure 4 As shown, Figure 4A schematic diagram of a graphical interface provided by an embodiment of the present invention, the user enters the object type in the object type input box and selects the corresponding dimming mode in the dimming mode, and after triggering the "OK" button to confirm the information, the terminal device can generate the corresponding object type information and dimming mode information, and send the object type information and dimming mode information to the lighting device selected by the user. In another embodiment, the user can also input the object type to the terminal device by uploading a photo of the object.

[0051] Step 102: determine the target object type according to the object type information, and determine the target dimming model according to the dimming mode information.

[0052] The lighting device determines the corresponding target object type according to the received object type information, determines the corresponding dimming mode according to the dimming mode information, and determines the target dimming model corresponding to the dimming mode. In this embodiment, the target dimming model is obtained in advance by training a neural network or a deep learning network, and each dimming mode corresponds to a target dimming model.

[0053] Step 103, control the motion component to drive the light source component to rotate at least one circle, so as to determine the target orientation and environmental color information through multiple environmental images collected by the image acquisition module, wherein the target orientation is the orientation of the position of the target object corresponding to the target object type.

[0054] After determining the target object type and the target dimming model, the lighting device needs to control the motion component to drive the light source component to rotate around the center of the circle for at least one circle, and control the image acquisition module to capture multiple environmental images during the rotation of the light source component. After the light source component rotates, the target object corresponding to the target object type is identified in the multiple environmental images captured by the image acquisition module. After the target object is identified, the target orientation corresponding to the target object is determined, wherein the target orientation is the orientation of the position of the target object corresponding to the target object type. When the lighting device faces the target orientation, the image acquisition module can face the target object. At the same time, the lighting device also needs to extract color information from multiple environmental images, and determine the environmental color information of the surrounding environment based on the color information extracted from the multiple environmental images. In one embodiment, the light source component of the lighting device is vertically downward in the initial state, and the camera of the lighting device captures the image directly below the lighting device after startup. If there is a target object in the image directly below, the lighting device can lock the target orientation corresponding to the target object in advance. After that, the lighting device controls the posture of the light source component to tilt at a certain angle, and controls the light source component to rotate at least one circle through the motion component to capture the environmental image.

[0055] In one embodiment, in step 103, controlling the motion component to drive the light source component to rotate at least one circle to determine the target orientation and environmental color information through multiple environmental images collected by the image acquisition module includes:

[0056] Step 1031: Control the motion component to drive the light source component to rotate for at least one revolution, and during the rotation, periodically control the image acquisition module to acquire an environmental image.

[0057] In this embodiment, the lighting device first controls the motion component to drive the light source component to rotate at least one circle, and during the rotation of the light source component, periodically controls the image acquisition module to acquire environmental images, wherein the duration of the cycle can be set according to actual needs.

[0058] Step 1032: After the motion component has completed its rotation, a target object corresponding to the target object type is identified in the multiple environment images taken by the image acquisition module.

[0059] After the motion component has completed its rotation, it is necessary to identify the target object corresponding to the target object type in the multiple environmental images taken by the image acquisition module. The target object recognition algorithm can use the existing algorithm, which can be selected according to actual needs and is not described in detail in this embodiment.

[0060] Step 1033: determine the rotation angle of the motion component when the environment image including the target object is collected, and determine the target orientation of the target object according to the rotation angle.

[0061] After the target object is identified, the environment image where the target object is located is further determined, and the rotation angle of the motion component when the environment image including the target object is collected is determined, and the target orientation of the target object is determined based on the rotation angle of the motion component. In one embodiment, the lighting device may identify the target object in multiple environment images respectively. In this case, the target orientation can be determined based on the earliest captured target object. Specifically, the lighting device first determines the shooting time of each environment image including the target object, and determines the target environment image with the earliest shooting time. Afterwards, the target orientation of the target object is determined based on the rotation angle of the motion component when the target environment image is collected, that is, the orientation of the light source component when the target environment image is captured is used as the target orientation.

[0062] Step 1034: determine environmental color information according to the multiple environmental images.

[0063] While determining the target orientation, the lighting device also needs to determine the ambient color information of the surrounding environment based on the multiple ambient images collected by the image acquisition module. Specifically, the lighting device first determines the color information of each ambient image. In this embodiment, the color information of each ambient image includes saturation, hue, and brightness. One ambient image corresponds to one saturation, one hue, and one brightness. After that, the average saturation, average hue, and average brightness of all ambient images are further determined to obtain the ambient color information.

[0064] Based on the above embodiment, the motion component is also used to adjust the target angle between the light source component and the axis perpendicular to the ground. For example, Figure 5 As shown, Figure 5 This is a schematic diagram of a motion assembly in accordance with an embodiment of the present invention adjusting a target angle between a light source assembly and an axis perpendicular to the ground. Figure 5 The θ in is the target angle. When the target orientation cannot be determined from multiple environment images, it also includes:

[0065] After adjusting the target angle between the light source assembly and the axis perpendicular to the ground through the motion assembly, the motion assembly is controlled to drive the light source assembly to rotate at least one circle to re-determine the target orientation and environmental color information through multiple environmental images captured by the image acquisition module.

[0066] In one embodiment, when the motion component drives the light source component to rotate, the image acquisition module may fail to capture the target object, resulting in the lighting device being unable to identify the target object in the captured environmental image, thereby failing to determine the target direction. In this case, the lighting device can adjust the target angle between the light source component and the axis perpendicular to the ground through the motion component, thereby changing the shooting range of the image acquisition module. After adjusting the target angle, the lighting device re-controls the motion component to drive the light source component to rotate at least one circle, so as to re-determine the target direction and environmental color information through the multiple environmental images captured by the image acquisition module. If the image acquisition module still fails to capture the target object after the re-rotation, the target angle can be adjusted again, and the motion component can be controlled to drive the light source component to rotate at least one circle. In addition, considering that the target angle between the light source component and the axis perpendicular to the ground generally has a maximum value, each time the target angle is adjusted, a preset angle can be adjusted each time, for example, the preset angle is 10°.

[0067] Step 104 : Control the motion component to drive the light source component toward the target direction, so as to acquire a target image of the target object through the image acquisition module and acquire spectral information of the target object through the spectral sensor.

[0068] After determining the target direction, the lighting device needs to re-control the motion component to drive the light source component toward the target direction. After the light source component is toward the target direction, the lighting device needs to control the image acquisition module to capture the target image of the target object, and control the spectral sensor to collect spectral information of the target object.

[0069] Step 105 : determining the lighting parameters of the light source assembly according to the target object type, the environmental color information, the target image, the spectrum information and the target dimming model, and controlling the light source assembly to emit light according to the lighting parameters.

[0070] After acquiring the target image and spectral information of the target object, it is necessary to further determine the lighting parameters of the light source assembly according to the target object type, environmental color information, target image, spectral information and target dimming model, and control the light source assembly to emit light according to the lighting parameters. Exemplarily, the target object type, environmental color information, target image, and spectral information can be input into the target dimming model to output the lighting parameters of the light source assembly through the target dimming model. In one embodiment, the lighting parameters of the light source assembly include brightness, color temperature and beam angle. After the lighting device adjusts the brightness, color temperature and beam angle of the light source assembly according to the lighting parameters, it controls the light source assembly to emit light.

[0071] Based on the above embodiment, in step 105, the lighting parameters of the light source assembly are determined according to the target object type, the environmental color information, the target image, the spectrum information and the target dimming model, including:

[0072] Step 1051: Determine object color information of the target image.

[0073] In another embodiment, the lighting device needs to extract object color information of the target image, where the object color information includes saturation, hue, and brightness.

[0074] Step 1052: Determine the material information and color temperature information of the target object according to the spectrum information.

[0075] In addition, the lighting device also needs to determine the material information and color temperature information of the target object based on the spectral information collected by the spectral sensor. Specifically, the lighting device can calculate the color coordinates (x, y) of the light source component based on the spectral information. The color coordinates are a parameter that describes the position of the color of the light source component on the chromaticity diagram. The calculated color coordinates are then compared with the color coordinates of the standard blackbody radiation spectrum, which is the radiation spectrum of the blackbody at different temperatures. The blackbody temperature with the smallest color difference from the color coordinates of the light source component is found by interpolation, which is the desired spectral color temperature. When determining the material information of the target object based on the spectral information, the existing atomic emission spectroscopy, atomic absorption spectroscopy, and X-ray fluorescence spectroscopy can be used. The specific process can refer to the prior art and will not be repeated in this embodiment.

[0076] Step 1053: input the target object type, environmental color information, object color information, material information, and color temperature information into the target dimming model to determine the lighting parameters of the light source assembly through the target dimming model.

[0077] After determining the object color information and the material information and color temperature information of the target object, the target object type, ambient color information, object color information, material information and color temperature information can be further input into the target dimming model to determine the lighting parameters of the light source assembly through the target dimming model.

[0078] In addition, in this embodiment, when training dimming models corresponding to different dimming modes, it is necessary to construct a training set of the dimming model according to the following parameters:

[0079] Data parameters (1) Saturation, hue and brightness of the object image.

[0080] Data parameters (2) Material information and color temperature information of the object.

[0081] Data parameter (3) saturation, hue and brightness of the overall environment.

[0082] Data parameter (4) Object type.

[0083] Data parameters (5) Required lighting parameters.

[0084] When constructing a training set, the data parameters (1) to (4) are input into the neural network model for training. The lighting parameters output by the neural network model during the training process are compared with the lighting parameters of the data parameters (5) to determine the error. The network parameters output by the neural network model are adjusted according to the error until the error of the lighting parameters output by the neural network model is within a preset range. In this way, a trained dimming model can be obtained.

[0085] As described above, an embodiment of the present invention provides a lighting control method. In the embodiment of the present invention, after the user sets the object type and dimming mode required for lighting on the terminal device, the terminal device generates corresponding object type information and dimming mode information, and sends the object type information and dimming mode information to the lighting device. After the lighting device determines the target object type and the target dimming model according to the object type information and the dimming mode information, the motion component is controlled to drive the light source component to rotate at least one circle, so as to identify the target direction and environmental color information of the target object through the multiple environmental images collected by the image acquisition module. After that, the lighting device can control the motion component to drive the light source component to move toward the target direction, so as to collect the target image of the target object through the image acquisition module and the spectral information of the target object through the spectral sensor, and determine the lighting parameters of the light source component according to the target object type, environmental color information, target image, spectral information and target dimming model, and control the light source component to emit light according to the lighting parameters. In the embodiment of the present invention, the lighting device can automatically identify the corresponding target object according to the type of object that the user needs to illuminate and illuminate the target object, and the lighting effect is determined according to the dimming mode selected by the user, which can improve the lighting effect on the object and solve the technical problem of poor lighting effect when using lights to illuminate objects in the prior art. In addition, in the lighting process, the embodiment of the present invention does not require the user to manually set the lighting parameters and adjust the light position, and the degree of intelligence is high, which further improves the user experience.

The above-mentioned integrated unit may be implemented in the form of hardware or in the form of software functional units.

[0097] If the integrated unit is implemented in the form of a software functional unit and sold or used as an independent product, it can be stored in a computer-readable storage medium. Based on this understanding, the technical solution of the present invention, in essence, or the part that contributes to the prior art, or all or part of the technical solution can be embodied in the form of a software product.

The aforementioned storage medium includes: U disk, mobile hard disk, read-only memory (ROM, Read-Only Memory), random access memory (RAM, Random Access Memory), disk or optical disk, etc. Various media that can store computer programs.

[0098] The embodiment of the present invention also provides a lighting control system, such as Figure 7 As shown, Figure 7The schematic diagram of the structure of the lighting control system provided in the embodiment of the present invention includes a control terminal 20 and a plurality of the above-mentioned lighting devices 10, and the control terminal 20 is used to communicate with each lighting device 10 and to communicate with the terminal device 30. The control terminal 20 is provided with a map of the environment space where the lighting device 10 is located, and the map records the coordinates, installation height, and orientation direction of the light source assembly when the rotation angle is at zero of each lighting device 10. In one embodiment, the control terminal can be a server in the cloud, and the server is wirelessly connected to each lighting device and the terminal device. The server is provided with a map of the environment space where the lighting device is located. The user can create a map after installing the lighting device in the environment space, and after recording the coordinates, installation height, and orientation direction of the light source assembly when the rotation angle is at zero of each lighting device in the map, the map is uploaded to the server.

[0099] The lighting device is also used to upload the current rotation angle of the motion component to the control terminal after the light source component is oriented toward the target.

[0100] The control terminal is used to receive the object height corresponding to the target object type sent by the terminal device; and after receiving the rotation angle sent by each lighting device, determine the target coordinates of the target object toward which each lighting device is directed in the map according to the rotation angle, the installation height and the object height; and when the distance between the corresponding target coordinates of any two lighting devices is within a preset distance, control the motion component of one of the lighting devices to rotate again to determine the new target direction.

[0101] In this embodiment, when the user inputs the object type in the terminal device, he / she also needs to further input the object height of the object type. After the terminal device determines the target object type according to the object type input by the user, it will send the object height corresponding to the target object type to the control terminal. After receiving the object height, the control terminal stores the object height. In another embodiment, the user can also set the object height in the control terminal and store it in the control terminal, and the control terminal will directly call the stored object height later. When the subsequent lighting device controls the light source component to face the target direction through the motion component, it will determine the rotation angle of the current motion component and upload the rotation angle of the motion component to the control terminal.

[0102] After receiving the rotation angle uploaded by the lighting device, the control terminal can determine the position of the target object facing the lighting device relative to the lighting device in the map based on the rotation angle sent by each lighting device, and then determine the horizontal distance of the target object relative to the lighting device based on the installation height, rotation angle and object height. For example, Figure 8 As shown, Figure 8A schematic diagram of the positional relationship between a target object and a lighting device provided in an embodiment of the present invention, Figure 8 The flower pot placed on the table is taken as the target object, where h2 is the object height of the flower pot, h1 is the installation height of the lighting equipment, and Figure 8 The position relationship and target angle θ shown in the figure can calculate the horizontal distance x1 of the target object relative to the lighting device. Finally, the control terminal can determine the target coordinates of the target object in the map according to the position of the target object relative to the lighting device and the distance from the lighting device.

[0103] After determining the target coordinates of the target object that each lighting device is facing, the control terminal will further determine whether the distance between the target coordinates corresponding to any two lighting devices is within a preset distance, where the preset distance can be set as needed. For example, in this embodiment, the preset distance can be set to 10 cm. When the distance between the target coordinates corresponding to any two lighting devices is within the preset distance, it means that the two lighting devices are illuminating the same target object. At this time, the control terminal needs to control the motion component of one of the lighting devices to rotate again, so as to re-determine the new target object through the multiple environmental images collected by the image acquisition module, thereby controlling the light source component to face the new target direction. It can be understood that the re-determined target object is different from the target object determined last time.

[0104] As described above, in the embodiment of the present invention, when the control terminal confirms that two lighting devices are lighting the same target object, it controls the motion component of one of the lighting devices to rotate again to find a new target object for lighting, thereby improving the utilization rate of the lighting devices.

[0105] An embodiment of the present invention also provides a terminal device, which is communicatively connected to a plurality of the above-mentioned lighting devices, and is used to determine a target lighting device among a plurality of lighting devices in response to a device selection instruction, and is used to determine object type information and dimming mode information in response to a parameter setting instruction, and send the object type information and dimming mode information to the target lighting device; and is used to determine a target rotation angle in response to a rotation angle adjustment instruction, and send the target rotation angle to the target lighting device, so as to control a motion component of the target lighting device to rotate to the target rotation angle.

[0106] In this embodiment, the user can select the target lighting device to be controlled on the terminal device, and set the object type and dimming mode that the target lighting device needs to illuminate. The specific setting process can refer to the description of step 101 in the above embodiment, which will not be repeated in this embodiment. In addition, when the subsequent target lighting device controls the light source component to face the target object through the motion component, if the user finds that the target lighting device and other lighting devices illuminate the same target object, the user can also re-control the direction of the light source component of the target lighting device on the terminal device so that the target lighting device faces the new target object. Specifically, the terminal device also provides a control interface for controlling the rotation angle of the lighting device, and the user can operate on the control interface to send a rotation angle adjustment instruction to the terminal device. When the terminal device detects the rotation angle adjustment instruction, it determines the target rotation angle according to the rotation angle adjustment instruction, and sends the target rotation angle to the target lighting device to control the motion component of the target lighting device to rotate to the target rotation angle. After the motion component of the target lighting device rotates to the target rotation angle and faces the new object, the target image of the new target object is re-collected and the spectral information of the new target object is collected through the spectral sensor to re-determine the lighting parameters corresponding to the new target object.

[0107] As mentioned above, the embodiment of the present invention also provides a terminal device, and the user can control the rotation angle of the lighting device on the terminal device. When the user confirms that two lighting devices are illuminating the same target object, the motion component of one of the lighting devices can be controlled by the terminal device to rotate again to find a new target object for illumination, thereby improving the utilization rate of the lighting device and also improving the flexibility of controlling the lighting device.
