Description

Technical Field

[0001] The present application relates to the field of control, and in particular to a light string control method, device, electronic device and storage medium. Background Art

[0002] A light string is a strip of lamps formed by connecting several lamp beads in series through wires. In actual use, the light string can be used straight, or it can be used in various shapes (such as stars, squares, triangles, etc.). When using light strings, in order to achieve more diverse effects, users sometimes need to make the lamp beads of the light string work asynchronously, such as using certain light effects and motion effects to control the lamp beads in the light string. At present, the light effects and motion effects of multiple lamp beads in a light string are usually fixed. For example, current lamp beads can often only achieve different light effects and motion effects according to user presets, and repeated light effects and motion effects can easily cause aesthetic fatigue to users.

[0084] In order to solve the technical problem of how to improve the flexibility and richness of lamp bead control in the prior art, the present application provides a light string control method, which can improve the flexibility and richness of lamp bead control.

[0085] Figure 1 A schematic diagram of a flow chart of a light string control method provided in an embodiment of the present application. The light string includes a plurality of lamp beads.

[0086] This method can be applied to one or more electronic devices such as light strings, smart phones, laptops, desktop computers, portable computers, servers, etc. In addition, the execution subject of this method can be hardware or software. When the above-mentioned execution subject is hardware, the execution subject can be one or more of the above-mentioned electronic devices. For example, a single electronic device can execute this method, or multiple electronic devices can cooperate with each other to execute this method. When the above-mentioned execution subject is software, this method can be implemented as multiple software or software modules, or it can be implemented as a single software or software module. No specific limitation is made here.

[0087] like Figure 1 As shown, the method specifically includes:

[0088] Step 101: Acquire a user image of a target user captured by a camera device.

[0089] In this embodiment, the camera device may be any one or more devices with a camera function. As an example, the camera device may be a camera.

[0090] The target user may be any user detected by the above-mentioned camera device.

[0091] The user image may be one or more images obtained by the above-mentioned camera device collecting images of the shooting area where the target user is located.

[0092] For example, when a user enters the shooting area of ​​a camera device and the camera device captures images of the shooting area, the user can be determined as a target user, and one or more images obtained by the camera device capturing images of the shooting area can be determined as user images.

[0093] Furthermore, in some cases, when a user image includes multiple images, the user image may represent a video of the target user.

[0094] The user image may be an image including the user's face, an image including the user's torso, or an image including the user's biometric features such as fingerprints and irises.

[0095] Step 102: determining the position and posture information of the target user based on the user image, wherein the position and posture information represents the user position and posture of the target user in the imaging area of ​​the imaging device.

[0096] In this embodiment, the posture information may represent at least one of the position and posture of the target user in the camera area of ​​the camera device. In addition, in some cases, the posture information may also include the identity of the user corresponding to the posture information, such as whether the user is a family member, a friend, a stranger, etc.

[0097] In some embodiments, the posture information can be acquired via a 2D sensor and a camera device.

[0098] As an example, the position and posture information of the target user may be determined by performing image recognition on the user image captured by the camera device.

[0099] Here, the above-mentioned image recognition may include at least one of the following: face recognition, human shape recognition, position detection, activity direction detection, human skeleton key point detection and behavior judgment, gesture recognition, etc.

[0100] Among them, for the above-mentioned face recognition and human shape recognition, face recognition in a broad sense can include a series of related technologies for building a face recognition system, including face image acquisition, face positioning, face recognition image preprocessing, identity confirmation and identity search, etc. Face recognition in a narrow sense refers specifically to the technology or system for identity confirmation or identity search through the face.

[0101] Face recognition belongs to biometric identification technology, which distinguishes individuals based on the biological characteristics of the organism (generally referring to humans). Biometric identification technology includes face, fingerprint, palm print, iris, retina, body shape, personal habits (such as the strength and frequency of keyboard tapping, signature), etc. The corresponding identification technologies include face recognition, fingerprint recognition, palm print recognition, iris recognition, retina recognition, body shape recognition, keyboard tapping recognition, signature recognition, etc.

[0102] Here, a person can be comprehensively identified through facial recognition, body shape recognition, and clothing color.

[0103] For the above position detection: the camera (i.e. the above camera device) can build its own coordinate system to obtain the relative position of the active object (such as the above target user) in the picture. Then, combined with the user drawing the family's focus area and interactive area in the picture in the coordinate system, it can be judged whether the active object has entered a certain key position.

[0104] For the above-mentioned activity direction detection: the camera device can first fix the angle, track and count the coordinates of the active object in each frame, so as to calculate the activity direction of the active object, up, down, left, right or other directions, and combine with the boundary of the home area drawn by the user to determine whether the active object is entering / exiting the home area, and further determine whether a person is currently passing by, going home or wandering around.

[0105] Regarding the above-mentioned human skeleton key point detection and behavior judgment: The detection of human skeleton key points can be mainly used to detect some key points of the human body, such as joints, limbs, facial features, etc., and describe the human body posture information through key points. Since the human body is flexible, various postures and shapes may appear, and a slight change in any part of the human body will produce a new posture. Activities such as waving, boxing, dancing, jumping, and falling are typical, and the current person's behavior can be judged by combining the detection of human skeleton key points and tracking the rules of their activity changes.

[0106] In addition, the position information of the target user may also be determined by a 2D sensor.

[0107] Among them, the 2D sensor can be a battery-powered sensor, including active transmitting and receiving devices, with low-power standby mode (1D standby mode) and working mode (2D working mode). For example, a 2D millimeter-wave radar is a sensor that detects the location area, existence, and movement trajectory of an object by measuring the angle and distance of the target relative to a reference position.

[0108] 2D sensors, such as millimeter wave radars, calculate the distance between a target (such as the target user mentioned above) and the radar by measuring the round-trip time of the signal. Specifically, the radar can emit a short pulse of millimeter wave signals that can propagate in the air. When it encounters a target, a portion of the signal can be reflected back by the target. The radar can receive this reflected signal and measure the round-trip time of the signal to calculate the distance between the target and the radar to achieve distance detection.

[0109] In addition, 2D sensors, such as millimeter wave radars, can also calculate the angle of a target (such as the target user mentioned above) by measuring the phase difference of the signal. Specifically, the radar can emit two adjacent millimeter wave signals with a phase difference between the two signals. When the two signals encounter a target, they can be reflected back by the target, and the phase difference between them can change. The radar receives this reflected signal and measures the change in the phase difference to calculate the angle of the target to achieve angle detection.

[0110] By combining distance and angle detection, the 2D sensor can accurately locate and track the target, that is, obtain the above-mentioned posture information.

[0111] Step 103: determine target illumination parameters based on the posture information and the target position information, wherein the target position information represents the relative position between the imaging area and the plurality of lamp beads, and the target illumination parameters are used to indicate illumination of the plurality of lamp beads respectively.

[0112] In this embodiment, the matching relationship between the user posture, the target position information and the illumination parameters can be preset. Thus, based on the target position information and the user posture obtained in step 102, the illumination parameters matching the user posture and the target position information can be determined, thereby obtaining the target illumination parameters.

[0113] Here, since the above-mentioned light string includes multiple lamp beads. Therefore, different target lighting parameters can be determined for different lamp beads. For example, if the above-mentioned light string includes 3 lamp beads, namely lamp bead A, lamp bead B and lamp bead C, then the target lighting parameter can indicate that the brightness of lamp bead A is 0, the brightness of lamp bead B is not 0, and the brightness of lamp bead C is 0; or, the target lighting parameter can indicate that the brightness of lamp bead A is 0, the brightness of lamp bead B is 50%, and the brightness of lamp bead C is 100%; or, the target lighting parameter can indicate that lamp bead A emits red light, lamp bead B emits yellow light, and lamp bead C emits green light.

[0114] In this embodiment, differences in one or more of the face recognition results, human figure recognition results, position detection results, activity direction detection results, human skeleton key point detection and behavior judgment results, and gesture recognition results may, but not necessarily, lead to differences in target illumination parameters.

[0115] Step 104: Control the plurality of lamp beads respectively according to the target illumination parameters.

[0116] In this embodiment, since the target illumination parameter is used to indicate the illumination of the plurality of lamp beads respectively, the plurality of lamp beads can be controlled respectively according to the target illumination parameter.

[0117] Target lighting parameters can be used to indicate the color, brightness, color switching frequency, etc. of the indicator light beads.

[0118] In some optional implementations of this embodiment, at least one of the following is used to determine the position and posture information of the target user based on the user image:

[0119] The first item is to determine whether the target user is located in a preset area based on the user image, and obtain the position information of the target user.

[0120] The above-mentioned position information may indicate whether the target user is located in a preset area.

[0121] The preset area may be one or more predetermined areas. The preset area may be located within the camera area of ​​the camera device. Thus, the camera device may capture an image of the camera area to determine whether the target user is located within the preset area.

[0122] The second item is to determine the location of the target user based on the user image and obtain the position information of the target user.

[0123] The above-mentioned position information may indicate the location of the target user, for example, the location of the target user in the above-mentioned camera area.

[0124] The third item is to determine the moving trajectory of the target user based on the user image and obtain the position information of the target user.

[0125] The above-mentioned posture information may represent the moving trajectory of the target user.

[0126] Here, after the camera device continuously obtains the location of the target user, the moving track of the target user can be determined based on the location of the target user.

[0127] The fourth item is to determine the behavior intention of the target user based on the user image and obtain the position information of the target user.

[0128] The above-mentioned posture information may represent the behavioral intention of the target user.

[0129] The above behavioral intentions may include at least one of the following: going home, leaving, singing, giving orders, dancing, inspiring, showing off, etc.

[0130] In practice, the behavioral intention of the target user can be determined by performing behavior recognition on user images.

[0131] In some application scenarios of the above optional implementations, the following method may be used to determine the target illumination parameters based on the pose information and the target position information:

[0132] First, based on the posture information and the target position information, target lamp beads and non-target lamp beads are determined from the plurality of lamp beads.

[0133] Among them, the target lamp bead is a lamp bead among the multiple lamp beads, the distance between which and the position of the target user is less than or equal to the target distance.

[0134] The target distance may be a predetermined distance. In addition, the target distance may also be determined based on the distance between the location of the target user and the location of the lamp bead.

[0135] Here, the relative position of the target user and the multiple lamp beads can be determined first through the posture information and the target position information. Further, the lamp beads whose distance to the position of the target user is less than or equal to the target distance can be determined, that is, the target lamp beads. And, among the multiple lamp beads, other than the target lamp beads are determined as non-target lamp beads.

[0136] As an example, the above target distance can be determined in the following manner: first, determine the lamp bead B that is closest to the position A where the target user is located, and then determine the distance between the lamp bead B and the position A as the target distance.

[0137] As another example, the target distance can also be determined in the following manner: first, determine the three lamp beads B, C, and D that are closest to position A where the target user is located, then determine the lamp bead B, C, and D that has the largest distance from position A (referred to as lamp bead E), and then determine the distance between lamp bead E and position A as the target distance.

[0138] The non-target lamp beads may be lamp beads other than the target lamp beads among the plurality of lamp beads.

[0139] Afterwards, the target illumination parameter of the target lamp bead is determined as the first parameter, and the target illumination parameter of the non-target lamp bead is determined as the second parameter.

[0140] As an example, the first parameter may indicate that the target lamp beads are displayed as a first preset color (eg, dark red), and the second parameter may indicate that the non-target lamp beads are displayed as a second color (eg, light red).

[0141] It can be understood that in the above application scenario, the lamp beads that are closer to the target user can be controlled to display according to the first parameter, and the lamp beads that are farther away from the target user can be controlled to display according to the second parameter. In this way, the location of the target user can be highlighted by controlling the lamp beads, further improving the flexibility and richness of the lamp bead control.

[0142] In some cases in the above application scenarios, when the first parameter indicates that the lamp beads are illuminated, the second parameter indicates that the lamp beads are turned off; when the first parameter indicates that the lamp beads are turned off, the second parameter indicates that the lamp beads are illuminated.

[0143] It can be understood that in the above case, the position of the target user can be mapped to the corresponding position of the lamp bead. For example, it can be achieved that where the person is, the light is turned on / off, and the rest of the positions are turned off / on, forming a chasing light effect.

[0144] In some optional implementations of this embodiment, the following method may be used to determine the target illumination parameters based on the pose information and the target position information:

[0145] First, based on the posture information and the target position information, the distance moved by the target user along a preset direction is determined to obtain the moving distance.

[0146] The moving distance may represent the distance that the target user moves along a preset direction.

[0147] Here, after the camera device continuously obtains the location of the target user, the location of the target user can be determined based on the posture information and the target position information, and then the movement trajectory of the target user can be determined.

[0148] Then, a quotient of the moving distance and a preset distance threshold is determined.

[0149] In practice, the quotient of the moving distance and the preset distance threshold can be calculated in real time.

[0150] Finally, the target illumination parameter is determined when the integer part of the quotient changes.

[0151] As an example, a lighting parameter set may be preset, wherein each lighting parameter in the lighting parameter set may represent a color that the target user likes (e.g., a color set for the target user). Afterwards, when it is determined that the integer part of the quotient has changed, a lighting parameter may be randomly determined from the lighting parameter set to obtain the target lighting parameter. Alternatively, when it is determined that the integer part of the quotient has changed, a lighting parameter that has not been selected may be selected from the lighting parameter set to obtain the target lighting parameter. Wherein, when all lighting parameters in the lighting parameter set have been selected, all lighting parameters in the lighting parameter set may be marked as not selected for subsequent selection.

[0152] It can be understood that in the above optional implementation, a lighting parameter can be changed every time the target user moves a preset distance threshold, thereby further improving the flexibility and richness of the lamp bead control.

[0153] The light string control method provided in the embodiment of the present application, the light string includes a plurality of lamp beads, the method acquires a user image of a target user captured by a camera device for controlling the lamp beads in the subsequent light string, and then determines the position information of the target user based on the user image, wherein the position information indicates the user position of the target user in the camera area of ​​the camera device, so as to identify the user position, and then determines the target illumination parameter based on the position information and the target position information, wherein the target position information indicates the relative position between the camera area and the plurality of lamp beads, and the target illumination parameter is used to indicate the illumination of the plurality of lamp beads respectively, so as to determine the relative position between the target user and the lamp beads, and finally, controls the plurality of lamp beads respectively according to the target illumination parameter, so as to automatically control the plurality of lamp beads to illuminate in a manner matching the position of the user relative to the lamp beads. Thus, the flexibility and richness of lamp bead control can be improved.

[0154] Figure 2 A flowchart of another light string control method provided in an embodiment of the present application. The light string includes a plurality of light beads. Figure 2 As shown, the method specifically includes:

[0155] Step 201: Acquire a user image of a target user captured by a camera device.

[0156] In this embodiment, step 201 and Figure 1 Step 101 in the corresponding embodiment is basically the same and will not be described again here.

[0157] Step 202: determining the position and posture information of the target user based on the user image, wherein the position and posture information represents the user position and posture of the target user in the imaging area of ​​the imaging device.

[0158] In this embodiment, step 202 and Figure 1 Step 102 in the corresponding embodiment is basically the same and will not be described again here.

[0159] Step 203: Identify the user image to obtain the identity information of the target user.

[0160] In this embodiment, when the user image includes a face image, the identity information of the target user can be obtained by performing face recognition on the user image; when the user image includes a fingerprint image, the identity information of the target user can be obtained by performing fingerprint recognition on the fingerprint image; when the user image includes an iris image, the identity information of the target user can be obtained by performing iris recognition on the user image.

[0161] The identity information may be used to indicate the identity of the target user.

[0162] Step 204, determining target illumination parameters based on the posture information, the target position information and the identity information, wherein the target position information represents the relative position between the camera area and the plurality of lamp beads, and the target illumination parameters are used to indicate the illumination of the plurality of lamp beads respectively.

[0163] In this embodiment, the correspondence between the posture information, the target position information, the identity information and the illumination parameters can be preset, so that based on the above matching relationship, the illumination parameters matching the posture information and the target position information determined in the above step 203 are determined and used as the target illumination parameters. Alternatively, the correspondence between the user position, the identity information and the illumination parameters can be set, so that after the user position of the target user is determined based on the posture information and the target position information, the illumination parameters matching the user position of the target user are determined based on the above matching relationship and used as the target illumination parameters.

[0164] Step 205: Control the plurality of lamp beads respectively according to the target illumination parameters.

[0165] In this embodiment, step 205 and Figure 1 Step 104 in the corresponding embodiment is basically the same and will not be described again here.

[0166] In some optional implementations of this embodiment, the following method may be used to determine the target illumination parameters based on the posture information, the target position information and the identity information:

[0167] First, it is determined whether the identity information indicates that the target user is a preset user.

[0168] The preset users may include one of the following: family members and friends.

[0169] Afterwards, when the identity information indicates that the target user is the preset user, the colors to be displayed of the plurality of lamp beads and the switching times of the colors to be displayed are determined based on the posture information and the target position information to obtain the target lighting parameters.

[0170] The target illumination parameters may include the color to be displayed by the lamp beads and the switching time of the color to be displayed.

[0171] As an example, the position, moving path and moving speed of the target user can be first determined based on the posture information and the target position information. Then, based on the user's position and moving path, the next area that the target user will move into is determined (predicted) from a predetermined set of areas to obtain the target area. Each area in the above area set can correspond to a color. Based on the position, moving path and moving speed of the target user, the moment when the target user moves into the target area is determined. Then, the color corresponding to the target area is determined as the color to be displayed; the moment when the target user moves into the target area is determined as the switching moment of the color to be displayed.

[0172] As another example, the moving speed of the target user can be first determined based on the posture information and the target position information. Then, based on the moving speed, the time required for the target user to move a preset distance is determined. The moment reached after the current moment has passed the time is determined as the switching moment of the color to be displayed. In this example, a color set needs to be set. Then, before reaching the switching moment, a color can be randomly determined from the above colors to obtain the target color. Alternatively, in determining the above color set, a color that has not been selected is selected to obtain the target color. Among them, in the case where all colors in the color set have been selected, all colors in the color set can be marked as not selected, so as to make subsequent selections.

[0173] It can be understood that in the above optional implementation method, by determining whether the target user is a preset user, the color to be displayed by the lamp bead and the switching time of the color to be displayed can be determined more specifically, thereby further improving the flexibility and richness of the lamp bead control.

[0174] It should be noted that, in addition to the above contents, this embodiment may also include Figure 1 The corresponding technical features described in the corresponding embodiments are realized Figure 1 For details, please refer to Figure 1 For the sake of brevity, the relevant description is not repeated here.

[0175] The light string control method provided in the embodiment of the present application can determine the target lighting parameters based on the identity information of the target user, so that the lighting effect presented by the lamp beads can be matched with the identity information of the target user, thereby further improving the flexibility and richness of the lamp bead control.

[0176] The following is an illustrative description of the embodiments of the present application, but it should be noted that the embodiments of the present application may have the features described below, but the following description does not constitute a limitation on the scope of protection of the embodiments of the present application.

[0177] At present, outdoor atmosphere lighting usually requires setting the lighting effect combination in advance, and cannot interact with people according to real-time situations. For example, when a family member comes home for a birthday, the outdoor atmosphere lighting recognizes her and switches the lighting effect. When playing on the lawn outdoors during festivals, children are playing games and you want to use ambient atmosphere lighting to accompany the children's activities to increase the interactive atmosphere.

[0178] Currently, in order to interact with lights, additional hardware is usually required. In this method, the camera (i.e., the above-mentioned camera device) can be used to perceive the environment. Therefore, this method combines the visual recognition and judgment capabilities of indoor and outdoor atmosphere lights and cameras to determine the user's presence, location, movement trajectory, who she / he is, her / his behavioral intentions, and interact with the atmosphere to enrich the light effects.

[0179] 1. Usage scenario: Add fun to scenes in life that require ambient lighting.

[0180] 1) Light-chasing interaction: When friends come to play, you can show off your light-chasing stunts to them.

[0181] The position of the moving object (that is, the target user mentioned above) is mapped to the corresponding position of the atmosphere light (that is, the light string mentioned above). Where the person is, the light will be on / off, and the rest of the positions will be off / on, and the color will change, forming a chasing light effect.

[0182] In addition, it can also support chasing light based on people's movements, and also support chasing light based on gestures such as raising hands and waving hands.

[0183] 2) Grid tricks interaction: Children play games in the yard, and playing games during festivals adds to the atmosphere.

[0184] As an example, see Figure 3A , Figure 3A A flowchart of an application scenario of a light string control method provided in an embodiment of the present application.

[0185] exist Figure 3A In the figure, different lighting effects (i.e., the above-mentioned target lighting parameters) can be presented in different areas. The grid interactive color area can be drawn very large and only one, or it can be drawn finely and subdivided one by one. In the figure, grids with different textures can correspond to different target lighting parameters, and grids with the same texture can correspond to the same target lighting parameters. The five-pointed star shape in the figure can indicate the location of the user (e.g., the target user).

[0186] 3) Family interaction: When the birthday comes, the family goes home and moves to a different scene.

[0187] When the family returns home, based on her preferences, the light changes to a different color with each step closer to the door.

[0188] As an example, see Figure 3B , Figure 3B A flowchart of an application scenario of another light string control method provided in an embodiment of the present application. Figure 3B In the process of moving along the moving track in the figure, the family member (corresponding to the target user) can change the light color she likes every time she gets closer to the door.

[0189] 4) Dancing interaction: Friends dancing in the yard can add to the atmosphere of the dance.

[0190] For fun scenes, such as dancing, if dancing is detected, the preset lively lighting effects will be automatically switched.

[0191] 5) In the future, based on user needs, there may be other AI (Artificial Intelligence) recognition and behavior detection algorithms that can be combined with lighting interactions to personalize the control of light strings.

[0192] 2. Equipment and capabilities included in the implementation plan:

[0193] This method includes a camera or other video recording device (ie, the above-mentioned video recording device), and outdoor monochrome lights or RGB / RGBW / RGBWW or other ambient light strings, which are used together.

[0194] The camera and the atmosphere light are interconnected through LAN, Bluetooth, Matter and other technologies, so that the instructions processed by the camera are sent to the atmosphere light.

[0195] 1) Camera: It has advanced AI capabilities. AI can run locally / in the cloud / on both local and cloud. The algorithms include at least face recognition, human figure recognition, hand waving detection, skeletal motion behavior detection, and walking direction detection.

[0196] 2) Light strings: outdoor light strings, indoor light strips, spotlights, Christmas lights, etc. The shape of the light string is not limited, but it needs to support single-point lighting effect control and segmented lighting effect control. In addition, a large number of interactive lighting effect libraries are preset in the atmosphere light, so that each subsequent action / intention can have a matching interactive lighting effect available.

[0197] 3. Implementation process:

[0198] 1) The user (e.g., target user) uses the camera area detection function to build a visual map, draw locations to divide the interactive area, specify event relationships, and specify interactive methods. In addition, the one-to-one control relationship between the visual map and the actual physical atmosphere light needs to be specified.

[0199] The user can preview the camera image in real time, draw single / multiple areas (the preset areas mentioned above) in detail in the editor, and specify the lighting control method (changing lights or chasing lights) of moving objects (such as people and cars) in each area.

[0200] For example, users can draw detailed ground grids and specify the lighting effects that correspond to when someone enters / exits each grid.

[0201] For another example, the user can draw a walking path and specify the lighting effect corresponding to each walking distance in the walking direction.

[0202] User Action:

[0203] First draw a large light interaction area in the camera, such as circling the area of ​​your home.

[0204] Select the light interaction area in the large interactive area, for example, you can choose to interact by block or by line. Multiple light interaction areas can be freely arranged and combined, and can be overlapped and crossed. In addition, each area can be marked for visualization.

[0205] Among them, you can interact by blocks, add color blocks, fill in color and specify lighting effects; interact by lines, draw moving lines and specify lighting effects. And you need to set a one-to-one correspondence between the points on the moving lines and the actual atmosphere lights in order to achieve tracking control of light tracking.

[0206] 2) Users use camera recognition to detect AI capabilities: specify which people and behavioral activities they want to interact with.

[0207] Designated person-to-person recognition: You can designate family members, strangers, or anyone else. Information is obtained based on face and shape recognition by the camera.

[0208] Specified behavior and behavior recognition: Based on the camera's skeleton detection and behavior judgment, it can be judged whether a person is walking, dancing, waving, etc. In addition, no behavior is restricted.

[0209] Activity location detection: The camera records the activity area drawn by the user, and when someone appears, it determines whether they are in the area.

[0210] Activity distance and movement direction tracking: The camera draws the activity trajectory of a moving person by associating consecutive frames, and determines whether his walking direction matches the movement direction specified by the user.

[0211] As an example, see Figure 3B and Figure 3C . Figure 3B In the scenario shown, it can be determined that the user's behavioral intention is to go home. Figure 3CIn the scenario shown, it can be determined that the user's behavioral intention is passing by.

[0212] User Action:

[0213] Choose a combination of people, behaviors, and assign specific lighting effects.

[0214] Optionally, you can combine the area / moving direction set above to make a combined response condition judgment.

[0215] 3) Based on the user's choices in the first two steps, the system recommends lighting effects that match the user's intention. After the user confirms the lighting effects, they are saved as preset interaction rules.

[0216] Lighting effect library factor: preset dynamic effects related to chasing lights, waving, dancing, games, and children. After the user completes the activity area and activity type selection in the first two steps, the background library recommends dynamic effects and lighting color combinations suitable for this scene through semantic combination and understanding. Users can choose from them or customize the corresponding lighting and dynamic effects.

[0217] For example, if a user chooses to wave their hands to interact, the AI ​​model can understand the intention behind it, guessing that the user's intention is to give orders, dance, inspire people, and show off, and understand that there is a demand for intense, fast, and rhythmic animations. The animations in the lighting effect library with factors such as impact, shining, advancing, and diffusion are recommended to users for selection. Users can directly choose from the ready-made animation recommendations, or they can make minor adjustments or completely customize them.

[0218] The light string has the ability to be controlled in sections and groups, and can be controlled one by one with the lighting effects.

[0219] User operations include: selecting interactive behaviors, selecting recommended interactive lighting effects, confirming the corresponding lighting relationships between lighting effects and light strings (segment groups), and saving rules.

[0220] 4) The camera determines the interactive rules in real time to control the lighting changes of the light string: real-time identification of objects and their behaviors, receiving gestures / behavior instructions from active objects, and real-time control of the lights.

[0221] After the camera uses its own computing power or cloud computing power to identify the attributes, behaviors and instructions of the objects in the picture, it combines the position drawn by the user and the event rules defined by the user to trigger the corresponding interactive lighting effect rules, which are sent to the atmosphere light through wireless communication protocols such as LAN / Bluetooth.

[0222] After receiving the instructions from the camera, the atmosphere light plays the specified lighting effects according to the rules, responds to the instructions of the active object, and completes the interaction.

[0223] The camera relies on computing power and network connection, and based on the user-set area / linear / person behavior interactive lighting effects, when conditions change, it must respond in real time to achieve continuous real-time calculation and real-time follow-up of lighting changes, ensuring a long-term and timely interactive experience. For example:

[0224] Interaction of grid lighting effects within the area: The camera calculates the intersection relationship between the specified object and the grid area in real time, and changes to the specified effect in real time.

[0225] Interaction with walking routes within the area: The camera calculates the position of the moving object in real time and matches it one by one with the preset interaction points of the atmosphere light.

[0226] Interaction of human behavior in the area: The camera recognizes real-time frame by frame, promptly judges changes in the subject in the picture and switches related effects.

[0227] In this method, the camera combined with visual AI can define precise interactions, allowing users to play with lights to produce rich lighting effects in combination with actual scenes, with rich interactive light effects: using camera vision technology in light interaction can achieve game-like interactions based on human areas and behaviors, thereby providing a new way to control light strings. In addition, this method can also set the interaction mode of home interaction areas and interactive objects through real-time camera images. By understanding the intention behind the computer vision behavior selected by the user, the corresponding lighting effects are recommended, realizing personalized lighting effect settings.
