Description

Technical Field

[0001] The present invention relates to the technical field of lighting interaction, and in particular to a regional perception interactive lighting device. Background Art

[0002] Interactive lighting installations are commonly seen in scenic spots, parks, exhibitions, public art projects, commercial spaces and entertainment venues. They are designed to enhance the atmosphere of the environment through lighting effects, provide educational content, or increase the fun and interactivity of the space.

[0003] Current interactive lighting installations generally change the color, brightness or pattern of lights according to preset programs or algorithms to create a dynamic, interactive visual experience.

[0004] Traditional interactive lighting installations mainly rely on preset programs or algorithms, which limits their flexibility and adaptability, resulting in a lack of personalization and dynamic changes in the interactive experience, making the interactive experience obtained by tourists tend to be consistent and lack of specificity and uniqueness. Summary of the invention

[0005] In view of the above-mentioned technical problems and defects, the purpose of the present invention is to provide a regional perception interactive lighting device, which can alleviate the technical problem that the lighting interactive experience lacks personalization and dynamic changes.

[0006] To achieve the above-mentioned purpose, the present invention provides an area perception interactive lighting device, comprising a camera unit, a first light irradiation unit, a direction adjustment mechanism and a control processing unit; the camera unit is used to capture a crowd image in a target area; the first light irradiation unit is used to irradiate children's interactive lights to the target area; the first light irradiation unit is connected to the direction adjustment mechanism, and the direction adjustment mechanism is connected to the control processing unit; the control processing unit is used to determine the real-time position of the children in the target area according to the crowd image, and control the direction adjustment mechanism to adjust the light irradiation angle of the first light irradiation unit according to the real-time position, so that the light irradiation angle is directed to within the area range of the real-time position.

[0007] The present invention captures real-time images of people in the target area through an integrated camera unit, and uses image recognition technology to accurately identify and locate the position of children. Subsequently, the control processing unit analyzes these image data, calculates the dynamic position of the child in real time, and intelligently directs the direction adjustment mechanism to adjust the illumination angle of the first light illumination unit to ensure that the light is always focused on the area where the child is active. This dynamic adjustment not only enhances interactivity, synchronizes the lighting effect with the real-time position of the child, and improves the personalization and dynamic changes of the lighting interaction, but also ensures the visual health and safety of the child by accurately controlling the illumination range of the light and avoiding the lighting design that directly illuminates the child's eyes.

[0008] In some embodiments, the area-aware interactive lighting device also includes a human body sensing unit and a second lighting unit, the second lighting unit being used to illuminate the target area with performance interactive lights, the human body sensing unit being disposed in the target area and connected to the control processing unit, the human body sensing unit being used to detect crowd flow in the target area, the control processing unit being used to control the second lighting unit to adjust the display content of the performance interactive lights according to the crowd flow.

[0009] By adopting the technical solution of the above embodiment, the function of the interactive lighting device is expanded by adding a human body sensing unit and a second lighting unit. The human body sensing unit can detect the flow of people in the target area in real time, which enables the device to dynamically adjust the display content of the interactive lighting performance according to the changes in the flow of people, thereby optimizing the audience's viewing experience. For example, when the flow of people is large, the device can automatically enhance the lighting effect to attract more audience attention; when the flow of people is small, it can display more delicate lighting effects to maintain the audience's interest. This intelligent adjustment mechanism improves the adaptability and interactivity of the lighting device, enabling it to better serve audience groups of different sizes.

[0010] In some embodiments, the human body sensing unit includes an infrared sensor, an ultrasonic sensor, or a lidar sensor.

[0011] By adopting the technical solution of the above embodiment, the device's ability to detect people in the target area is enhanced by introducing infrared sensors, ultrasonic sensors or laser radar sensors as human body sensing units. These sensors each have unique advantages and can provide high-precision crowd flow and location information. Infrared sensors are suitable for heat detection, ultrasonic sensors are suitable for distance measurement, and laser radar sensors provide high-precision three-dimensional environmental scanning. The combined use of these technologies enables the device to work stably under various environmental conditions, improves the reliability and accuracy of the device, and provides a solid data foundation for the intelligent adjustment of lighting effects.

[0012] In some embodiments, the control processing unit is further used to determine the crowd flow in the target area according to the crowd image.

[0013] By adopting the technical solution of the above embodiment, the control processing unit is equipped with the function of analyzing crowd images to determine crowd flow, which further improves the intelligence level of the device. This function enables the device to more accurately evaluate the flow of people in the target area, thereby adjusting the lighting effect more finely. For example, the device can automatically adjust the brightness and color of the lights according to the increase in crowd flow to meet different viewing needs. Compared with traditional sensor detection, this flow detection method based on image analysis provides more intuitive and comprehensive crowd flow information, making the interaction of the lighting device more natural and humane.

[0014] In some embodiments, the control processing unit is further used to determine the age range of the child based on the crowd image, and control the first lighting unit to adjust the display content of the child interactive lighting based on the age range.

[0015] By adopting the technical solution of the above embodiment, the personalized service capability of the device is enhanced by enabling the control processing unit to determine the age range of children based on the crowd image and adjust the display content of the children's interactive lights accordingly. This function enables the device to provide customized lighting effects according to the characteristics and needs of children of different age groups. For example, for younger children, the device can display colorful and simple pattern lighting effects; while for older children, it can display more complex and dynamic lighting effects. This age-based lighting adjustment not only improves the children's interactive experience, but also makes the device more in line with the needs of children's development.

[0016] In some embodiments, the control processing unit is further used to determine the gender of the child based on the crowd image, and control the first lighting unit to adjust the display content of the child interactive lighting based on the gender of the child.

[0017] By adopting the technical solution of the above embodiment, the personalized service capability of the device is further enhanced by enabling the control processing unit to determine the gender of the child based on the crowd image and adjust the display content of the children's interactive lighting accordingly. This function enables the device to provide customized lighting effects according to the preferences of children of different genders. For example, for girls, the device can display lighting effects with soft colors and beautiful patterns; while for boys, it can display lighting effects with bright colors and dynamic patterns. This gender-based lighting adjustment not only improves the children's interactive experience, but also makes the device more in line with the children's psychological and aesthetic needs.

[0018] In some embodiments, the control processing unit is further used to predict the movement path of the child based on the crowd image, and control the direction adjustment mechanism to adjust the lighting angle of the first lighting unit based on the movement path.

[0019] By adopting the technical solution of the above embodiment, the control processing unit is enabled to predict the movement route of the child based on the crowd image and adjust the lighting angle accordingly, thereby further improving the interactivity and dynamic response ability of the device. This function enables the device to predict the movement trend of the child in advance and adjust the lighting effect accordingly to achieve a more natural and smooth interactive experience. For example, when the child moves in a certain direction, the device can automatically transfer the lighting effect to the area where the child is about to arrive, so that the child is always in the focus of the light. This lighting adjustment based on behavior prediction not only improves the child's sense of participation, but also makes the device more intelligent and advanced.

[0020] In some embodiments, the area perception interactive lighting device also includes a voice interaction unit, which is arranged in the target area and is used to receive voice information issued by tourists. The control processing unit is connected to the voice interaction unit and is used to control the first lighting unit or the second lighting unit to adjust the lighting display content according to the voice information.

[0021] By adopting the technical solution of the above embodiment, the interactive mode of the device is expanded by adding a voice interactive unit. The voice interactive unit can receive and analyze the voice information of the visitors, so that the device can adjust the light display content according to the voice command. This function enables the device to provide a more intuitive and convenient interactive experience. For example, visitors can use voice commands to select different lighting effects, or interact with the device through simple dialogue. This voice-based interactive method not only improves the participation of visitors, but also makes the device more humane and friendly.

[0022] In some embodiments, the control processing unit is further used to determine the emotional state of the visitor according to the voice information, and control the first lighting unit or the second lighting unit to adjust the lighting color according to the emotional state.

[0023] By adopting the technical solution of the above embodiment, the control processing unit is enabled to determine the emotional state of the tourists according to the voice information and adjust the light color accordingly, thereby further improving the emotional response ability of the device. This function enables the device to provide corresponding lighting effects according to the emotional changes of tourists. For example, when it is detected that the tourists are in a high mood, the device can display a lighting effect with warm colors and high brightness; and when it is detected that the tourists are in a low mood, it can display a lighting effect with soft colors and low brightness. This emotion-based lighting adjustment not only improves the interactive experience of tourists, but also makes the device more intimate and intelligent.

[0024] In some embodiments, the area perception interactive lighting device also includes a broadcast unit, and the control processing unit is also used to determine the distance between the child and the guardian based on the crowd image. When the distance is greater than a set threshold, the control processing unit is used to control the broadcast unit to issue a child safety reminder.

[0025] By adopting the technical solution of the above embodiment, by adding a broadcast unit and enabling the control processing unit to determine the distance between the child and the guardian based on the crowd image, and issuing a safety prompt when the distance exceeds a preset threshold, the safety protection function of the device is enhanced. This function enables the device to issue a warning in time when the child is separated from the guardian, reminding the guardian to pay attention to the safety of the child. For example, when the device detects that the child is a certain distance away from the guardian, a safety prompt such as "Please pay attention to your child" can be issued through the broadcast unit. This safety prompt based on distance monitoring not only improves the safety of children, but also reduces the pressure on guardians, making the device more practical and reliable.

[0026] One or more technical solutions provided by the present invention have at least the following technical effects or advantages: 1. The present invention provides a highly personalized interactive experience. By capturing images of people in the target area through the camera unit, combined with advanced image analysis and machine learning algorithms of the control processing unit, the device can identify the age range and gender of children and predict their movement routes. This information enables the device to dynamically adjust the lighting display content and illumination angle to adapt to the needs and behaviors of different children, thereby providing a customized interactive lighting experience for each child.

[0027] 2. By integrating human body sensing units, including infrared sensors, ultrasonic sensors or lidar sensors, the device can detect the flow of people in the target area in real time and adjust the display content of the interactive lighting according to these data. In addition, the control processing unit can predict the movement path of children based on the crowd image and realize dynamic tracking of the lights, so that the device can intelligently adapt to environmental changes and crowd behavior, providing a more natural and smooth interactive experience.

[0028] 3. Through the voice interaction unit, the device can receive and analyze the voice information of tourists, determine the emotional state of tourists based on the voice information, and adjust the light color accordingly to provide emotional support. At the same time, the device also includes a broadcast unit. When the distance between the child and the guardian exceeds the preset threshold, the control processing unit will trigger the broadcast unit to issue a safety prompt to enhance the safety of the child.

[0032] It should also be noted that, unless otherwise clearly specified and limited, in the embodiments of the present invention, the terms such as "setting" and "connection" should be understood in a broad sense. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two components; it can be a wired communication connection or a wireless communication connection. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to the specific circumstances. The embodiments of the present invention are described in detail below.

[0033] The embodiment of the present invention provides a regional perception interactive lighting device, such as Figure 1 and 2 As shown, it includes a camera unit 1, a first light irradiation unit 2, a direction adjustment mechanism 3 and a control processing unit 4; the camera unit 1 is used to capture images of the crowd in the target area; the first light irradiation unit 2 is used to irradiate children's interactive lights to the target area; the first light irradiation unit 2 is connected to the direction adjustment mechanism 3, and the direction adjustment mechanism 3 is connected to the control processing unit 4; the control processing unit 4 is used to determine the real-time position of the children in the target area according to the crowd image, and control the direction adjustment mechanism 3 to adjust the light irradiation angle of the first light irradiation unit 2 according to the real-time position, so that the light irradiation angle is within the area range of the real-time position.

[0034] This embodiment captures real-time images of people in the target area through the integrated camera unit 1, and uses image recognition technology to accurately identify and locate the position of the child. Subsequently, the control processing unit 4 analyzes these image data, calculates the dynamic position of the child in real time, and intelligently directs the direction adjustment mechanism 3 to adjust the illumination angle of the first light illumination unit 2 to ensure that the light is always focused on the area where the child is active. This dynamic adjustment not only enhances interactivity, synchronizes the lighting effect with the real-time position of the child, and improves the personalization and dynamic changes of the lighting interaction, but also ensures the visual health and safety of the child by accurately controlling the illumination range of the light and avoiding the lighting design that directly illuminates the child's eyes.

[0035] In some embodiments, the control processing unit 4 determines the real-time position of the child in the target area based on the crowd image mainly in the following way. First, the control processing unit 4 uses advanced image recognition technology to analyze the crowd image captured by the camera unit 1. It will identify and distinguish in the image based on the child's unique physical characteristics, such as height, body proportion, etc. At the same time, it may also be combined with the characteristics of the color and pattern of the clothing often worn by the child to further improve the accuracy of recognition. Once the position of the child in the image is identified, the control processing unit 4 will convert the position information in the image into the actual position information in the target area through the conversion algorithm of the image coordinates and the actual space coordinates, thereby determining the real-time position of the child. In addition, in order to ensure the accuracy and real-time nature of the position, the control processing unit 4 will continuously receive new crowd images for analysis and processing, and timely update the position information of the child, so as to better control the direction adjustment mechanism 3 to adjust the lighting angle.

[0036] Then, when the control processing unit 4 determines the real-time position of the child, it will calculate the direction vector from the lighting unit to the child's position. Then, the control processing unit 4 converts this direction vector into a control instruction that the direction adjustment mechanism 3 can understand. The control instruction generally contains specific parameters for adjusting the lighting angle, such as rotation angle, inclination, etc. The direction adjustment mechanism 3 is usually composed of mechanical components such as motors and gears, and can perform precise angle adjustments in multiple directions. The control processing unit 4 sends instructions to the direction adjustment mechanism 3 to drive the lighting unit to make corresponding angle adjustments. During the adjustment process, the control processing unit 4 will continuously receive feedback information, such as the actual angle of the current lighting unit, to ensure that the lighting angle is accurately facing the area of ​​the child's real-time position.

[0037] In this way, a dynamic interaction between the light and the child's position is achieved, bringing a more interesting and personalized experience to children.

[0038] In this embodiment, a plurality of first light irradiation units 2 can be provided. The plurality of first light irradiation units 2 can irradiate the target area from different angles, ensuring that no matter where the child is in the target area, the light can be covered, greatly improving the comprehensiveness and coherence of the light interaction.

[0039] At the same time, multiple lighting units can work together through the control processing unit 4 to more accurately adjust the lighting angle according to the real-time position of the child, thereby achieving a more delicate lighting interactive effect. In terms of lighting display content, multiple first lighting units 2 can combine to create more diverse lighting patterns and color changes, bringing children a more fantastic and wonderful visual experience. In addition, when one of the lighting units fails, the other units can continue to work, ensuring the stability and reliability of the entire interactive lighting device.

[0040] Multiple first light irradiation units 2 can also illuminate children in different positions at the same time, so that each child can experience a unique interactive light experience. The control processing unit 4 can control different light irradiation units to adjust the angles according to the real-time positions of multiple children, ensuring that each child can be noticed by the light. In this way, in a scene with many children, no child will be ignored. Moreover, multiple light irradiation units can display a richer combination of light effects, creating a more colorful interactive environment for multiple children.

[0041] For example, different lighting units can present different colors or patterns. When multiple children interact together, the lighting effects are more diverse, which increases the fun and attraction of interaction between children. At the same time, multiple lighting units can also adjust the lighting display content according to the age, gender and other characteristics of different children to meet the personalized needs of each child.

[0042] In some embodiments, Figure 2 As shown, the area perception interactive lighting device also includes a human body sensing unit 5 and a second light irradiation unit 6. The second light irradiation unit 6 is used to irradiate the performance interactive light to the target area. The human body sensing unit 5 is arranged in the target area and connected to the control processing unit 4. The human body sensing unit 5 is used to detect the crowd flow in the target area. The control processing unit 4 is used to control the second light irradiation unit 6 to adjust the display content of the performance interactive light according to the crowd flow.

[0043] This embodiment further improves interactivity and adaptability by adding a human body sensing unit 5 and a second light irradiation unit 6. The human body sensing unit 5 is arranged in the target area, and can detect the crowd flow in the area in real time, and transmit the data to the control processing unit 4. The control processing unit 4 intelligently adjusts the performance interactive light display content of the second light irradiation unit 6 according to the received crowd flow information to adapt to audience groups of different sizes.

[0044] For example, when the crowd flow is large, the control processing unit 4 may instruct the second lighting unit 6 to display a more spectacular and dynamic lighting effect to attract and entertain more audiences; while when the crowd flow is small, it may be adjusted to a softer or more delicate lighting performance to create a suitable viewing atmosphere. Such a design allows the lighting device to be flexibly changed according to actual usage, providing a more personalized and dynamic interactive experience.

[0045] In some embodiments, the human body sensing unit 5 includes an infrared sensor, an ultrasonic sensor or a laser radar sensor.

[0046] Specifically, infrared sensors work by detecting infrared radiation of a specific wavelength emitted by the human body. When a person enters the sensor's detection range, the intensity of the infrared radiation captured by the sensor changes, triggering a signal. This sensor can also work effectively in dark environments and is often used in applications such as automatic doors, security systems, and lighting controls to detect and monitor the movement of people.

[0047] Ultrasonic sensors measure distance by emitting high-frequency sound waves and receiving echoes of these sound waves reflected from obstacles. When the sound waves encounter the human body, they reflect, and the sensor calculates the distance based on the time difference between the emitted and received sound waves. This sensor is not affected by light conditions and is suitable for a variety of environments. It is often used in distance measurement, object detection, and obstacle avoidance systems.

[0048] LiDAR sensors use laser beams for fast, high-precision distance measurement and environmental scanning. It determines the distance to the target object by emitting laser pulses and measuring the time it takes for these pulses to reflect back. LiDAR sensors are capable of generating detailed three-dimensional maps of the surrounding environment and are widely used in self-driving cars, drone navigation, terrain mapping, and advanced obstacle avoidance systems, favored for their high accuracy and fast response time.

[0049] The control processing unit 4 integrates the data collected by these human body sensing units 5 to accurately detect the crowd flow and distribution in the target area, thereby intelligently controlling the second lighting unit 6 to adjust the display content of the performance interactive lighting to achieve a more accurate and dynamic interactive effect.

[0050] In some embodiments, the control processing unit 4 is further configured to determine the crowd flow in the target area according to the crowd image.

[0051] Specifically, the control processing unit 4 uses image analysis technology to process the crowd image taken by the camera unit 1. It will identify each individual in the image, and distinguish different people by extracting individual features and identifying algorithms. Then, the control processing unit 4 will compare and analyze the continuous multi-frame crowd images. If new individuals appear in the images at different time points, or the positions of existing individuals have changed significantly, it can be judged that there is a flow of people. Then, the control processing unit 4 will count the number of different individuals that appear within a certain period of time to estimate the crowd flow in the target area. At the same time, in order to improve accuracy, the control processing unit 4 will also consider factors such as the shooting angle and field of view of the image to correct the statistical results. By continuously receiving new crowd images and analyzing them, the control processing unit 4 can update the crowd flow information of the target area in real time.

[0052] In some embodiments, the control processing unit 4 is further used to determine the age range of the children according to the crowd image, and control the first light irradiation unit 2 to adjust the display content of the children's interactive light according to the age range.

[0053] Among them, the control processing unit 4 determines the age range of children based on the crowd image mainly through advanced image analysis algorithms. The control processing unit 4 will first analyze the physical characteristics of the children in the crowd image, such as height, body proportion, etc. Usually, younger children are shorter and more rounded. At the same time, the control processing unit 4 will also observe the facial features of the children, such as eye size, facial contour, etc. Young children have relatively large eyes and softer facial contours. In addition, the judgment will be made in combination with the children's clothing characteristics. Children of different age groups often have different dressing styles.

[0054] After determining the age range of the children, the control processing unit 4 controls the first light irradiation unit 2 to adjust the display content of the children's interactive light according to different age ranges. For younger children, the light display content may be more colorful, with simple and cute patterns to attract their attention and stimulate their curiosity. For older children, the light display content can be more complex and varied, with some dynamic effects and interactive elements added to meet their higher cognitive needs and desire for exploration.

[0055] In some embodiments, the control processing unit 4 is further used to determine the gender of the child based on the crowd image, and control the first light irradiation unit 2 to adjust the display content of the child interactive light according to the gender of the child.

[0056] Specifically, the control processing unit 4 will analyze the appearance characteristics of the children in the image. Generally speaking, girls usually have longer hair and may wear hair accessories. The colors of their clothes may tend to be softer colors such as pink and purple, and their clothing styles may also have designs with more feminine characteristics such as skirts. Boys have relatively short hair and may wear more blue, green and other colors. Their clothing styles may have designs with more masculine characteristics such as shorts and jeans. At the same time, the control processing unit 4 will also observe the facial features of the children. Girls' facial contours may be relatively soft, while boys' lines may be tougher.

[0057] Once the gender of the child is determined, the control processing unit 4 controls the first light irradiation unit 2 to adjust the display content of the children's interactive light according to the gender. If it is a girl, the light display content can be more dreamy and romantic, such as flowers, butterflies and other patterns, and the color can also be mainly pink. For boys, the light can show some adventurous and technological content, such as spaceships, robots and other patterns, and the color is mainly blue.

[0058] In some embodiments, the control processing unit 4 is further used to predict the movement path of the child based on the crowd image, and control the direction adjustment mechanism 3 to adjust the light irradiation angle of the first light irradiation unit 2 based on the movement path.

[0059] Specifically, the control processing unit 4 will continuously analyze the continuous crowd images and identify the position changes of the child in the image. By tracking the position of the child in multiple frames of images, the child's current moving direction and speed can be determined. Then, combined with the environmental information of the target area, such as terrain, obstacle distribution, etc., and the overall flow trend of the crowd, the control processing unit 4 uses a prediction algorithm to infer the child's possible route of action. For example, if a child is moving towards a specific amusement facility and the surrounding crowd has a similar direction, then the control processing unit 4 will predict that the child may continue to move in this direction.

[0060] Once the child's route is predicted, the control processing unit 4 will control the direction adjustment mechanism 3 to adjust the light irradiation angle of the first light irradiation unit 2. It will adjust the light irradiation angle to the position that the child will reach in advance according to the predicted route, ensuring that the light can always follow the child's movements and provide the child with a continuous interactive light experience. This design makes the lighting device more intelligent and humane, and enhances the interactive effect between children and lights.

[0061] In this embodiment, the control processing unit 4 uses the prediction algorithm to infer the possible action route of the child mainly through the following aspects.

[0062] First, the control processing unit 4 analyzes the position change trajectory of the child in the past period of time. The child's position information is extracted from the continuous crowd images, and the child's moving speed, direction, acceleration and other parameters are calculated. If the child has been moving steadily in a certain direction for a period of time, it can be preliminarily determined that the child may continue to move forward in this direction for a distance.

[0063] Secondly, the environmental factors of the target area are considered. The control processing unit 4 will obtain the map information of the target area, including the location of the amusement facilities, the direction of the passage, the distribution of obstacles, etc. If the child is currently approaching an amusement facility, and this amusement facility has a greater attraction to the child in past observations, then the control processing unit 4 will predict that the child has a greater probability of moving in the direction of the amusement facility. At the same time, if there is a passage leading directly to a certain area, and the child is near this passage, it will also increase the possibility of the child moving along the passage.

[0064] Furthermore, the overall flow trend of the crowd is analyzed. If the surrounding crowd mostly moves in a certain direction, the child may be influenced by the crowd and follow the crowd. The control processing unit 4 will comprehensively consider factors such as the density and flow speed of the crowd to determine whether the child is likely to be driven by the crowd and change the route of action.

[0065] Finally, the control processing unit 4 may also use a machine learning algorithm to continuously optimize the prediction algorithm and improve the accuracy of predicting the child's action route by learning and training a large amount of children's action data in similar scenarios. In this way, as time goes by and data accumulates, the control processing unit 4 can more accurately infer the child's possible action route.

[0066] In some embodiments, Figure 2 As shown, the area perception interactive lighting device also includes a voice interaction unit 7, which is arranged in the target area and is used to receive voice information from tourists. The control processing unit 4 is connected to the voice interaction unit 7 and is used to control the first lighting unit 2 or the second lighting unit 6 to adjust the lighting display content according to the voice information.

[0067] Among them, the voice interaction unit 7 in the area perception interactive lighting device adds a richer interactive experience to the entire device. The voice interaction unit 7 is set in the target area and can receive voice information from tourists. When tourists issue voice commands, the voice interaction unit 7 transmits these voice messages to the control processing unit 4. After receiving the voice information, the control processing unit 4 will use voice recognition technology to analyze and process it. If the voice information is related to controlling the first light irradiation unit 2, the control processing unit 4 will adjust the display content of the children's interactive light according to the specific command content.

[0068] For example, if a visitor says "make the light brighter", the control processing unit 4 will increase the brightness of the first light irradiation unit 2; if he says "change the color", the color of the light will be adjusted. Similarly, if the voice information involves the second light irradiation unit 6, the control processing unit 4 will also adjust the display content of the interactive light performance accordingly, such as adding special effects, changing the dynamic mode of the light, etc. In this way, visitors can interact with the light device through voice, making the light display of the entire target area more personalized and diversified.

[0069] In some embodiments, the control processing unit 4 is further used to determine the emotional state of the visitor according to the voice information, and control the first lighting unit 2 or the second lighting unit 6 to adjust the lighting color according to the emotional state.

[0070] First, the control processing unit 4 uses speech analysis technology to process the received speech information. It analyzes the voice characteristics such as pitch, speech speed, and volume. Generally speaking, high pitch, fast speech speed, and high volume may indicate that the tourist is in an excited or agitated emotional state; while low pitch, slow speech speed, and low volume may imply that the tourist is relatively calm or depressed. At the same time, the control processing unit 4 also performs semantic analysis on the content of the speech. For example, positive and cheerful words may indicate that the tourist is in a good mood, while negative and depressed words may mean that the tourist is in a bad mood.

[0071] Once the emotional state of the visitor is determined, the control processing unit 4 will control the first lighting unit 2 or the second lighting unit 6 to adjust the light color according to the different emotional states. If the visitor is in an excited state, the control processing unit 4 may change the light to a bright and vivid color, such as red, orange, etc., to enhance the cheerful atmosphere. When the visitor is in a low mood, the light can be adjusted to a soft and warm color, such as blue, yellow, etc., to give people a feeling of comfort and relaxation. For a calm emotional state, the light can choose a more elegant color, such as lavender, light green, etc., to create a tranquil atmosphere.

[0072] In this way, the lighting installation can dynamically adjust according to the emotional state of the visitors, bringing visitors a more intimate interactive experience.

[0073] In some embodiments, the area perception interactive lighting device also includes a broadcast unit 8, and the control processing unit 4 is also used to determine the distance between the child and the guardian based on the crowd image. When the distance is greater than a set threshold, the control processing unit 4 is used to control the broadcast unit 8 to issue a child safety reminder.

[0074] First, the control processing unit 4 analyzes the position and behavior of the child in the crowd image. If the child has a relatively close physical contact with an adult, such as holding hands, being held in arms, etc., then the adult is likely to be the guardian. At the same time, the control processing unit 4 observes the interactive behavior between the child and the adult. For example, if the adult frequently pays attention to the child, arranges clothes for the child, or gives food, etc., this also increases the possibility that the adult is the guardian. In addition, the control processing unit 4 also considers the similarity of appearance features. If the child and an adult have certain similarities in facial features, skin color, hairstyle, etc., it may also indicate that they are a parent-child relationship. The control processing unit 4 can also make a judgment in combination with the continuity in time. If in a continuous crowd image, an adult always keeps a close distance with the child and pays attention to the child, then the adult is likely to be the guardian.

[0075] The control processing unit 4 uses an image recognition algorithm to identify children and guardians in the crowd image, and accurately locates their positions in the image by analyzing their appearance features, clothing features, etc. Then, the control processing unit 4 converts the position information in the image into coordinate information in the actual space. This usually requires the use of known image parameters, such as shooting angle, focal length, etc., as well as the actual size information of the target area.

[0076] Once the coordinates of the child and the guardian in the real space are determined, the control processing unit 4 can use a mathematical formula to calculate the straight-line distance between them. For example, a geometric method such as the Pythagorean theorem can be used to calculate the distance between two points.

[0077] By continuously analyzing new crowd images, the control processing unit 4 can update the distance information between the child and the guardian in real time, so that timely measures can be taken to ensure the safety of the child when necessary. When the distance between the child and the guardian exceeds a preset threshold, a safety prompt is issued to remind the guardian to pay attention to the safety of the child. For example, when the device detects that the child is a certain distance away from the guardian, a safety prompt such as "Please pay attention to your child" can be issued through the broadcast unit. This safety prompt based on distance monitoring not only improves the safety of the child, but also reduces the pressure on the guardian, making the device more practical and reliable.

[0078] The embodiment of the present invention provides a highly intelligent area-aware interactive lighting device, which integrates a camera unit 1, a first light irradiation unit 2, a direction adjustment mechanism 3, a control processing unit 4, and a variety of sensing and interactive units to provide children and tourists with a safe, interactive, and educational lighting environment. The camera unit 1 is responsible for capturing images of people in the target area, while the first light irradiation unit 2 irradiates the interactive light designed for children into the area according to the instructions of the control processing unit 4. The direction adjustment mechanism 3 dynamically adjusts the irradiation angle of the light according to the real-time position of the child to ensure that the light is always focused on the children's activity area.

[0079] In addition, the device also includes a human body sensing unit 5 and a second lighting unit 6, the latter is used to perform interactive lighting, and the human body sensing unit 5 detects the flow of people and transmits data to the control processing unit 4 so as to adjust the light display content according to the flow. The human body sensing unit 5 may include an infrared sensor, an ultrasonic sensor or a lidar sensor to ensure high-precision crowd detection. The control processing unit 4 can not only determine the flow of people, but also analyze the crowd image, identify the age range and gender of children, and then adjust the light display content to meet the needs of children of different ages and genders.

[0080] The control processing unit 4 can also predict the child's route of action and adjust the lighting angle accordingly to achieve dynamic tracking of the light. The device also integrates a voice interaction unit 7 to receive and analyze the voice information of tourists, control the light display content, and can judge the emotional state of tourists based on the voice information and adjust the light color to respond to emotional changes. Finally, the device also includes a broadcast unit 8. When the distance between the child and the guardian exceeds a preset threshold, the control processing unit 4 will trigger the broadcast unit 8 to issue a safety reminder to enhance the safety of the child.

[0081] In summary, the embodiments of the present invention realize an interactive lighting system that can respond to the behaviors of children and tourists in real time through intelligent control and multiple sensing technologies, which not only enhances interactivity and entertainment, but also improves safety and educational value, and provides an innovative lighting solution for public spaces.
