Description

Technical Field

[0001] This invention relates to the field of noise control technology, and more specifically, to a noise reduction system, method, apparatus, equipment, and medium for kitchens. Background Technology

[0002] In the kitchen environment, noise pollution is one of the main factors affecting user experience. Current measures to control kitchen noise primarily focus on three levels: source control, propagation path control, and receiver point control. Regarding source control, the most common approach is to optimize the structure of the fan or motor of the noisiest equipment in the kitchen—such as the range hood—to reduce its operating noise. While this method is widely adopted and relatively effective, its noise reduction has a physical limit, making further sensory improvement difficult. Regarding propagation path control, common methods include installing sound-absorbing materials (such as sound-absorbing cotton) inside or around the equipment, or using active noise control (ANC) technology. Sound-absorbing materials have some suppression effect on high-frequency noise, but their effect on low-frequency noise is limited; while active noise cancellation technology, although theoretically advantageous, is susceptible to contamination or aging of components such as speakers in the highly greasy and variable acoustic environment of a kitchen, leading to performance degradation and difficulty adapting to dynamic changes in the noise spectrum. Regarding receiver point control, existing technologies largely rely on users wearing earplugs, noise-canceling headphones, or protective helmets. While such solutions can isolate noise to some extent, they also bring problems such as inconvenience in use, obstruction of normal voice communication, and impact on auditory environmental perception, resulting in a poor user experience.

[0003] In summary, existing kitchen noise control technologies generally suffer from limited noise reduction effects, poor adaptability, and unsatisfactory user experience. There is an urgent need for a new noise reduction system for kitchens to solve the noise reduction problems existing in current technologies. Summary of the Invention

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0014] In one specific embodiment, the noise reduction system for kitchens described in this application can be applied to kitchens.

[0015] Figure 1 This is a schematic diagram of a noise reduction system for a kitchen according to an exemplary embodiment. This specification provides method operation steps as shown in the embodiments or flowcharts, but based on conventional or non-inventive labor, more or fewer operation steps may be included. The order of steps listed in the embodiments is merely one possible execution order among many and does not represent the only possible execution order. In actual system or server product execution, the methods shown in the embodiments or drawings can be executed sequentially or in parallel (e.g., in a parallel processor or multi-threaded processing environment). Specifically, as shown... Figure 1 As shown, this application introduces an embodiment of a noise reduction system for a kitchen. The noise reduction system for the kitchen may include an image module, a control module, a noise processing module, and a projection module; the image module, the noise processing module, and the projection module are respectively connected to the control module; the image module and the noise processing module are respectively connected to the projection module. The image module is used to acquire human detection results and target head positions in the kitchen; The control module is used to acquire the noise of kitchen appliances corresponding to kitchen appliances in the kitchen when the human detection result obtained by the image module indicates that there is a human body in the kitchen; and to activate the noise processing module and the projection module when the noise of the kitchen appliances is greater than a first preset noise. The noise processing module generates a target noise reduction wave based on the noise from the kitchen appliances obtained by the control module; The projection module is used to project the target noise reduction wave generated by the noise processing module onto the target head position obtained by the image module.

[0016] In one specific embodiment, the human body detection result is used to indicate whether there is a human body in the kitchen, the target head position can be the head position of the human body in the kitchen; the kitchen appliance noise can be the noise generated by the appliances when the human body uses the appliances in the kitchen; the first preset noise can be the noise threshold that needs to be noise-treated; the target noise sound wave can be the sound wave that masks the noise. Specifically, the noise reduction system for the kitchen may include an image module, a control module, a noise processing module, and a projection module. The image module, noise processing module, and projection module are each connected to the control module, allowing the control module to obtain the noise of kitchen appliances based on the human detection results received from the image module. This noise is then compared to a first preset noise level. If the kitchen appliance noise is greater than the first preset noise level, the control module activates the noise processing module and the projection module. Optionally, the image module and noise processing module are also connected to the projection module, allowing the projection module to project the target noise-reduced wave generated by the noise processing module onto the target head position obtained by the image module. Specifically, the projection module is equipped with a directional speaker with a pan-tilt unit, enabling the directional speaker to project the target noise-reduced wave onto the target head position. Optionally, after activation, the noise processing module generates a corresponding target noise-reduced wave based on the kitchen appliance noise obtained by the control module.

[0017] In an optional embodiment, the image module is further configured to acquire a kitchen image and determine the human body detection result and the target head position based on the kitchen image.

[0018] In one specific embodiment, the image module includes an image sensor, preferably a CMOS or CCD sensor, whose resolution, frame rate, and dynamic range are specially selected to adapt to changes in kitchen lighting. For example, high dynamic range (HDR) technology is used to simultaneously capture details in the bright areas of the stove flames and the dark areas of the cabinet shadows; an optical lens is also provided, with an appropriate focal length and angle of view (such as a wide-angle lens) selected according to the size of the kitchen space to ensure coverage of the main operating areas (such as the stove, sink, and worktop).

[0019] Specifically, the image module continuously acquires images at a fixed frame rate (e.g., 15fps) to meet the real-time response requirements of the noise reduction system. Optionally, the image module employs a corresponding deep learning processing algorithm to process the acquired images. Specifically, a deep learning-based object detection model can be used for object detection, and either a single-stage detector (e.g., YOLO, SSD) or a two-stage detector (e.g., Faster) can be used. A variant of R-CNN, optionally, the model is first trained using a large-scale, carefully labeled human body dataset in a kitchen scene. This dataset should include various occlusion scenarios (half the body obscured by a cabinet), various poses (bending over to pick something up, standing on tiptoe to retrieve an object), various lighting conditions, and users wearing different clothing to ensure the model's generalization ability. The detection model is then optimized. Optionally, considering the limited computing resources of embedded kitchen devices, optimization operations such as pruning, quantization, and knowledge distillation are needed to enable real-time operation at the edge. The model takes the acquired kitchen image as input and outputs human body detection results, specifically human bounding boxes, which are rectangular boxes that define the position and size of each human instance in the image. Further, based on the detected human bounding boxes, human pose estimation algorithms (such as OpenPose, HRNet, and MoveNet) are used to predict the two-dimensional coordinates of multiple key joints of the human body. Specifically, key points such as the nose, eyes, ears, shoulders, and elbows are regressed within the human bounding boxes. Key points of the head (such as the center of the nose or eyes) are directly used to calculate the target head position.

[0020] In the above embodiments, by setting the model algorithm in the image module to acquire and process images in the kitchen, the human body detection results and the target head position are obtained, which realizes the convenience and accuracy of image processing, improves the accuracy of the acquisition results and positions, and thus improves the accuracy and convenience of noise processing.

[0021] In an optional embodiment, the control module is further configured to acquire a preset noise and a preset sound wave file, and the noise processing module is further configured to generate the target noise reduction wave based on the preset noise, the preset sound wave file and the kitchen appliance noise acquired by the control module.

[0022] In one specific embodiment, a preset sound wave file is used to store noise comparison results, denoised noise waves, and the correspondence between the noise comparison results and the denoised noise waves. Optionally, the comparison results are used to indicate the magnitude comparison between the kitchen appliance noise and the preset noise. Specifically, when the human detection results obtained by the image processing module indicate the presence of a human body, the control module also obtains the preset noise and the preset sound wave file. Optionally, the preset sound wave file can be set by the user at the initial stage of using the noise reduction system. Correspondingly, the user can also modify the preset sound wave file before using the noise reduction system and store the preset sound wave file in the noise reduction system so that the noise reduction system can call the preset sound wave file. Further, when the control module obtains the kitchen appliance noise, the preset noise, and the preset sound wave file, a target denoised noise wave is generated based on the obtained kitchen appliance noise, the preset noise, and the preset sound wave file.

[0023] In the above embodiments, the noise processing module generates a target noise reduction wave by using the preset noise, kitchen appliance noise and preset sound wave file obtained by the control module, thereby reducing the complexity of the target noise reduction wave and improving the user experience.

[0024] In an optional embodiment, the noise processing module is further configured to compare the noise of the kitchen appliance with the preset noise to obtain a noise comparison result; and to generate the target noise reduction wave based on the noise comparison result and the preset sound wave file.

[0025] In one specific embodiment, the target noise reduction wave can be set to pleasant masking sound waves of different levels, optionally, such as music sound waves; the preset noise includes a first preset noise, a second preset noise, and a third preset noise. Optionally, the first preset noise is less than the second preset noise, and the second preset noise is less than the third preset noise. Accordingly, the kitchen appliance noise is first compared with the first preset noise. If the kitchen appliance noise is greater than the first preset noise, the kitchen appliance noise is then compared with the second preset noise. If the kitchen appliance noise is less than or equal to the second preset noise, a first noise comparison result is generated. Based on the first noise comparison result and the preset sound wave file, a first target noise reduction wave is generated. Optionally, the first target noise reduction wave can be a first-level target noise reduction wave, i.e., the lowest-level noise reduction wave. Optionally, if the kitchen appliance noise is greater than the second preset noise, the kitchen appliance noise is then compared with the third preset noise. The system compares noise levels. If the kitchen appliance noise is less than or equal to a third preset noise level, a second noise comparison result is generated. Based on this second noise comparison result and a preset sound wave file, a second target noise reduction wave is generated. Optionally, the second target noise reduction wave can be a second-level target noise reduction wave, i.e., a noise reduction wave one level higher than the lowest level noise reduction wave. Optionally, if the kitchen appliance noise is greater than a third preset noise level, a third noise comparison result is generated. Based on this third noise comparison result and a preset sound wave file, a third target noise reduction wave is generated. Optionally, the third target noise reduction wave can be a third-level target noise reduction wave, i.e., the highest level noise reduction wave. Optionally, this application can also set multiple different preset noise levels and kitchen appliance noise comparisons when setting preset noise and preset sound wave files, thereby generating more levels of target noise reduction waves based on the preset sound wave files to better improve the user experience.

[0026] In the above embodiments, the convenience of generating target noise reduction waves is improved by generating noise comparison results by comparing kitchen appliance noise with preset noise and generating target noise reduction waves from preset sound wave files; and by generating target noise reduction waves of different levels based on different noise comparison results, the adaptability and noise reduction effect of noise reduction are improved, thereby enhancing the user experience.

[0027] In an optional embodiment, the system further includes a communication module connected to the control module; The control module is also used to acquire sound detection results outside the kitchen, and when the sound detection results indicate that there is sound outside the kitchen, to activate the communication module and generate communication commands. The communication module is used to respond to the communication command generated by the control module, acquire the target sound outside the kitchen, and play the target sound.

[0028] In one specific embodiment, the sound detection result is used to indicate whether there is sound outside the kitchen; the communication command is used to indicate whether to start sound acquisition and play sound; specifically, the system also includes a communication module, which is connected to the control module. Optionally, the control module uses a sound detector to detect sound outside the kitchen. Optionally, the sound detector can be located outside the kitchen. Optionally, the sound detector is equipped with a recognition system to recognize human voices. Accordingly, when the sound detector detects human voices, it generates a sound detection result indicating that there is sound outside the kitchen and transmits it to the control module. Accordingly, the control module obtains the corresponding sound detection result, generates a communication command, and starts the communication module. Further, upon receiving the communication command, the communication module responds to the communication command, that is, it begins communication between the inside and outside of the kitchen. Optionally, the communication module acquires the target sound and plays the target sound.

[0029] In the above embodiments, by setting the communication module to enable communication between people inside and outside the kitchen under noise conditions, the smoothness and convenience of communication between people inside and outside the kitchen are improved, thereby enhancing the user experience.

[0030] In an optional embodiment, the communication module includes a sound pickup unit and a sound playback unit, the sound pickup unit and the sound playback unit being connected. The sound pickup unit is used to acquire the target sound; The sound playback unit is used to play the target sound acquired by the sound pickup unit.

[0031] In one specific embodiment, the communication module includes a sound pickup unit and a sound playback unit. The sound pickup unit and the sound playback device are connected so that the sound picked up by the sound pickup unit is transmitted to the sound playback unit for playback. Specifically, when the communication module starts communication, the sound pickup unit is activated to pick up human voices. Specifically, the sound pickup unit uses a sound pickup device to pick up the sound. Optionally, the sound pickup device can be a microphone or other device. Further, the sound pickup unit acquires the target sound and transmits the target sound to the sound playback unit. Correspondingly, the sound playback unit uses a sound playback device to play the target sound. Optionally, the sound playback device can be a speaker or other device.

[0032] In the above embodiments, sound is picked up by the sound pickup unit and played by the sound playback unit, which improves communication efficiency, saves resources, and enhances user experience.

[0033] This invention provides a noise reduction system for a kitchen, including an image module, a control module, a noise processing module, and a projection module. The image module, noise processing module, and projection module are all connected to the control module. The image module is used to acquire human detection results and target head positions within the kitchen, improving the purposefulness and accuracy of noise reduction. The control module, when the human detection results acquired by the image module indicate the presence of a human in the kitchen, acquires the noise of the corresponding kitchen appliances. If the kitchen appliance noise exceeds a first preset noise level, the noise processing module and projection module are activated, improving noise reduction efficiency. The noise processing module generates a target noise reduction wave based on the kitchen appliance noise acquired by the control module, improving the adaptability of the generated noise reduction wave. The projection module projects the target noise reduction wave generated by the noise processing module onto the target head position acquired by the image module, improving the accuracy of noise reduction. This noise reduction system achieves targeted noise reduction, improves noise reduction accuracy, adaptability, and efficiency, and ultimately enhances the user experience.

[0034] The following describes a noise reduction method for a kitchen provided by an embodiment of this application. This method is based on the aforementioned noise reduction system for a kitchen.

[0035] In one specific embodiment, the noise reduction system in the user's kitchen continuously issues noise reduction commands based on a preset time interval. Correspondingly, the noise reduction system responds to the noise reduction commands by continuously acquiring the human body detection results and the target head position in the kitchen. Then, when the human body detection results indicate the presence of a human body in the kitchen, the noise of the kitchen appliances is acquired. Optionally, the noise reduction system also continuously acquires the noise of the kitchen appliances, and simultaneously acquires a preset sound wave file and a preset noise. The kitchen appliance noise and the preset noise are then compared to obtain a noise comparison result. Based on the noise comparison result and the preset sound wave file, a target noise reduction wave is generated, and the target noise reduction wave is projected onto the target head position to achieve specified noise reduction for the human body. Optionally, the process of generating the target noise reduction wave will not be described in detail here.
