Description

Technical Field

[0001] This application relates to the field of wine storage technology, such as a method and device for managing wine in a wine cabinet, and a wine cabinet. Background Technology

[0002] In related technologies, wine cabinets have become an important piece of equipment for storing wine because they can provide a professional storage space with constant temperature and humidity for wine (e.g., wine).

[0003] In the process of implementing the embodiments of this disclosure, it was found that the related technology has at least the following problems:

[0004] Existing wine cabinets only have basic temperature and humidity control functions. When selecting wines, users need to manually check the wine labels or rely on experience to judge the maturity of the wines. Furthermore, it may be necessary to open the wines for testing. This method is not only inefficient, but also prone to human misjudgment, resulting in a poor drinking experience.

[0005] Meanwhile, different users have different preferences for wine flavors, and the storage of wines in wine cabinets is complex, ranging from dozens to hundreds of bottles. It is impractical for users to judge the maturity of each wine individually when selecting wines. Therefore, there is an urgent need for a solution that can intelligently analyze the maturity of wines in the wine cabinet and recommend wines with suitable maturity levels to users, thereby improving the intelligence of wine cabinet management.

[0006] It should be noted that the information disclosed in the background section above is only used to enhance the understanding of the background of this application, and therefore may include information that does not constitute prior art known to those skilled in the art.

[0035] It should be noted that, unless otherwise specified, the embodiments and features described in the present disclosure can be combined with each other.

[0036] The wine cabinet 100 provided in this embodiment is as follows: Figure 1 As shown, the wine cabinet 100 includes a cabinet body 110 and a management device 500 (600) for the wines in the wine cabinet.

[0037] Specifically, a back panel light 111 is provided on the back panel of the cabinet 110, and a wine management device 500 (600) for wine management in the wine cabinet is electrically connected to the back panel light 111 and is installed on the cabinet 110.

[0038] Optionally, the cabinet 110 is provided with a cabinet door 112 that can be opened and closed. The cabinet door 112 is a transparent display glass or a transparent display screen, so that users can intuitively view the storage status of the wine in the wine cabinet.

[0039] Optionally, the wine management device 600 for the wine cabinet includes a processor that can detect a target area in front of the wine cabinet and determine whether a user is in that target area. When the user is determined to be in the target area, the processor can acquire the user's identity information and turn on the backlight of the wine cabinet. After the backlight is turned on, the processor can acquire images of each wine in the wine cabinet and analyze the maturity of each wine based on the images. Based on the maturity of each wine and the user's identity information, the processor can recommend wines to the user.

[0040] In conjunction with the wine cabinet described above, this disclosure provides a method for managing wines in a wine cabinet. The executing entity of this management method can be the aforementioned processor, such as... Figure 2 As shown, the management method includes:

[0041] S201, the processor obtains the user's identity information when the user is in the target area in front of the wine cabinet.

[0042] Specifically, the target area is a section in front of the wine cabinet where the wines stored inside can be observed through the cabinet doors. If a user is in this target area, it indicates that they may need to select wines from the cabinet for consumption. Therefore, in this case, it is necessary to obtain the user's identity information and understand their needs and preferences in order to recommend suitable wines based on those preferences.

[0043] Optionally, a human body detection device can be installed on the cabinet of the wine cabinet to detect whether there is a user in the target area in front of the wine cabinet.

[0044] Optionally, a facial recognition device can be installed on the cabinet of the wine cabinet to identify the identity information of users in the target area.

[0045] S202, the processor turns on the back panel light of the wine cabinet and obtains a picture of each wine in the wine cabinet.

[0046] Understandably, the interior of a wine cabinet is typically dark, and under these conditions, photos of the wine may suffer from blurriness and color distortion. This can lead to lower accuracy in subsequent analysis of the wine's maturity based on these images.

[0047] Turning on the backlight of the wine cabinet provides ample and even lighting for the wines. Good lighting reduces shadows in wine photos, helps to restore the wine's true color, and allows the photos to highlight the outlines and color variations of the contents, making the depth and distribution of colors and the presence of impurities more apparent. This improves the accuracy of subsequent analysis of the wine's maturity based on the images.

[0048] Optionally, when the backlight is turned on, the backlight can emit warm white light of 4000k to 5000k.

[0049] Optionally, cameras are installed inside the wine cabinet (one on each side and one between every two wine shelves) to capture clearer images of each wine.

[0050] S203, the processor analyzes the maturity of each wine based on the wine images.

[0051] Specifically, wine maturity refers to the chemical changes that occur in the internal components of a wine after it has been aged or matured for a certain period of time following its brewing, achieving a more harmonious, complex, and balanced state. Higher maturity generally results in a more rounded taste and richer aromas, but over-maturation can also lead to flavor loss or spoilage. In particular, wine maturity can be determined by analyzing its age and quality.

[0052] Specifically, wine images clearly show the depth and distribution of color, which can then be used to determine the wine's age. For example, younger red wines typically appear deep purple or ruby ​​red, gradually changing to garnet, yellowish-brown, or even brown as they age. Similarly, a purple rim on a red wine indicates a younger vintage, while an orange or brown rim suggests a longer aging period. Likewise, white wines deepen in color with age, changing from lemon yellow to golden yellow, amber, or even brown.

[0053] Specifically, images of the wine can clearly indicate whether impurities or sediment are present, and the quality of the wine can be determined based on this assessment. For example, if a wine contains only a small amount of impurities or sediment and is generally clear and transparent, its quality is considered high. Conversely, if a wine contains a large amount of impurities or sediment and is generally cloudy, its quality is considered low.

[0054] Therefore, embodiments of this disclosure can analyze the maturity of each wine based on wine images.

[0055] S204: The processor recommends wines to users based on the maturity of each wine and the user's identity information.

[0056] Specifically, user identity information can clarify user needs and preferences, determining what flavors of wine they like. The maturity of the wine can determine its flavor profile. Therefore, wine recommendations can be made based on the maturity of each wine and the user's identity information. For example, if the user's identity information identifies them as a wine connoisseur who typically prefers wines with strong aging potential and complex flavors, then wines with higher maturity can be recommended.

[0057] In this embodiment, when a user enters the target area in front of the wine cabinet, after turning on the backlight of the wine cabinet, the color and sediment of each wine can be analyzed by examining the acquired images, thus determining the maturity of the wine. By obtaining the user's identity information, the user's preferences and habits can be understood, and wines with suitable maturity levels for the user's consumption can be matched. Therefore, this embodiment can intelligently analyze the maturity of the wines in the wine cabinet and recommend wines with suitable maturity levels to the user, improving the intelligence level of wine cabinet management.

[0058] This disclosure provides another method for managing wines in a wine cabinet, such as... Figure 3 As shown, the management method includes:

[0059] S301: When the user is in the target area in front of the wine cabinet, the processor obtains the user's identity information.

[0060] S302, the processor turns on the back panel light of the wine cabinet and obtains a picture of each wine in the wine cabinet.

[0061] S303, the processor extracts the liquid area from each wine image.

[0062] Specifically, wine images may contain interfering elements such as bottle labels, reflections, bubbles, and bottle necks. Analyzing the entire image directly would present numerous distracting factors; for example, the shadow on the bottle bottom label might be mistaken for sediment. Therefore, it is necessary to first extract the wine liquid area from each wine image.

[0063] Optionally, extracting the liquid region from each wine image includes: using an object detection algorithm to determine the bottle and liquid in the wine image; separating the bottle color and wine color in the wine image through color analysis; and performing image segmentation on the bottle and liquid in the wine image based on the bottle color and wine color to determine the liquid region in the wine image.

[0064] Specifically, the YOLOv3 or YOLOv5 algorithm can be used as the object detection algorithm to identify and locate the bottles and liquid in wine images.

[0065] Specifically, a bottle color database needs to be established in advance, and then color analysis is used to separate the bottle color and wine color in the wine images based on the database. Specifically, color analysis methods include HSV color analysis or RGB color analysis.

[0066] Specifically, image segmentation of the bottle and liquid in a wine image based on bottle and liquid color can separate the liquid area from the background, removing interfering factors such as the bottle and its label. In particular, a pre-trained deep learning model (e.g., a convolutional neural network CNN) can be used for image segmentation.

[0067] S304, the processor identifies the color characteristics and sediment characteristics of the wine liquid area.

[0068] Specifically, the maturity of a wine needs to be determined by analyzing its age and quality. The age of a wine can be determined based on the color characteristics of a specific region of the liquid, while the quality can be determined based on the sediment characteristics of that region. Therefore, after extracting the wine region, it is necessary to identify its color and sediment characteristics.

[0069] Specifically, an AI recognition model is pre-built to identify the color and sediment characteristics of the wine liquid area.

[0070] The S305 processor determines the maturity of each wine based on color and sediment characteristics.

[0071] Specifically, a first correspondence between color features and sediment features and wine maturity is pre-defined, and the processor can determine the wine maturity corresponding to the color features and sediment features based on the first correspondence.

[0072] For example, taking the classification of white wine maturity into 5 levels as an example, the first correspondence can be shown in Table 1 below:

[0073] Table 1

[0074]

[0075] For example, taking the classification of red wine maturity into 5 levels as an example, the first correspondence can be shown in Table 2 below:

[0076] Table 2

[0077]

[0078] The S306 processor recommends wines to users based on the maturity of each wine and the user's identity information.

[0079] In this embodiment of the disclosure, when analyzing the maturity of a wine based on its image, it is necessary to first extract the wine liquid area from the image, and then extract the color and sediment features within the wine liquid area to identify the maturity of the wine. This reduces the impact of factors such as the wine itself and its label on the accuracy of maturity identification.

[0080] In some embodiments, recommending wines to a user based on the maturity of each wine and the user's identity information includes: determining the drinking stage of each wine based on its maturity; determining the user's needs and preferences based on the user's identity information; and recommending wines to the user based on the drinking stage of each wine and the user's needs and preferences.

[0081] Specifically, a second correspondence between the maturity of a wine and its drinking stage is pre-defined, and the drinking stage of the wine corresponding to the maturity of the wine can be determined based on the second correspondence.

[0082] For example, taking the classification of wine maturity into 5 levels as an example, the second correspondence is shown in Table 3 below:

[0083] Table 3

[0084] Wine maturity The stage of drinking the wine New wine season Let it sit for a while; it will taste better after it has matured. Lockdown period It's drinkable, but it hasn't reached its optimal ripeness. rising period It's ready to drink; it's at its peak ripeness. peak period It's drinkable now, but its optimal ripeness has passed. Aging period During the decline, some parts were already corrupt.

[0085] For example, the characteristics of a red wine at different stages of maturity are shown below:

[0086] (1) Characteristics of the new wine period:

[0087] Color: Deep purplish-red or bluish-purple, with a bright hue.

[0088] Aroma: Primarily fresh fruity, possibly with a slight hint of raw green or grassy notes.

[0089] Taste: High acidity, tight tannins, rough texture, and relatively thin body.

[0090] (2) Characteristics of the closed period:

[0091] Color: The color gradually changes from deep purplish-red to ruby ​​red.

[0092] Aroma: The fruity notes begin to soften, and there may be a slight hint of spice or vanilla from the oak barrels.

[0093] Taste: The acidity and tannins are still noticeable, but the texture is becoming rounder and more complex.

[0094] (3) Characteristics of the rising phase:

[0095] Color: The color further changes to pomegranate red, and the edges may be slightly lighter.

[0096] Aroma: The fruity aroma gradually transforms into more complex aromas, such as jam, spices (cloves, cinnamon), leather, etc.

[0097] Taste: Acidity and tannins begin to balance, the body becomes fuller, and the astringency of tannins gradually decreases.

[0098] (4) Characteristics of peak period:

[0099] Color: The color changes to a deep ruby ​​red or garnet red, with higher transparency.

[0100] Aroma: The aroma is rich and complex, with tertiary aromas including dried fruit, tobacco, coffee, and truffle.

[0101] Taste: A perfect balance of acidity, tannins and fruit flavors; full-bodied, smooth on the palate, with a long finish.

[0102] (5) Characteristics of the aging period:

[0103] Color: The color gradually changes to brick red or brown.

[0104] Aroma: Fruity and spicy aromas gradually weaken, and oxidative aromas such as mushrooms and earth may appear.

[0105] Taste: Acidity and tannins are further reduced, the body of the wine becomes softer, but the overall flavor may be slightly bland.

[0106] Specifically, when entering user identity information, the wine cabinet needs to require users to fill in their taste preferences for wines (e.g., preferences for aroma, taste, etc.). Therefore, user needs and preferences can be determined based on user identity information.

[0107] Specifically, by determining a user's needs and preferences based on their identity information, it becomes clear which stage of drinking the user's preferred flavors are at. Therefore, based on the drinking stage of each wine and the user's needs and preferences, wine recommendations can be made to the user.

[0108] Specifically, users can be recommended multiple wines, and different recommendation indices can be set for each wine.

[0109] Optionally, the display device on the wine cabinet can be installed on the cabinet body, at the front of the wine rack, or the cabinet door can be made into a transparent display screen. Information recommending wines to the user is displayed on the wine cabinet's display device.

[0110] This disclosure provides another method for managing wines in a wine cabinet, such as... Figure 4 As shown, the management method includes:

[0111] S401: When the user is in the target area in front of the wine cabinet, the processor obtains the user's identity information.

[0112] S402, the processor turns on the back panel light of the wine cabinet and obtains a picture of each wine in the wine cabinet.

[0113] The S403 processor analyzes the maturity of each wine based on its images.

[0114] The S404 processor recommends wines to users based on the maturity of each wine and the user's identity information.

[0115] S405, the processor receives user feedback information.

[0116] S406, the processor adjusts the wine recommendation strategy based on user feedback.

[0117] In this embodiment, after tasting the recommended wines, the user can receive feedback (e.g., the recommendation was too acidic or too astringent) to identify areas where the recommendation strategy was flawed. Therefore, the wine recommendation strategy can be adjusted based on user feedback, leading to more accurate wine recommendations in the future.

[0118] In some embodiments, an eye-tracking device is installed inside the wine cabinet, and the management method further includes: using the eye-tracking device to capture the user's gaze dwell data; determining the target wine in the wine cabinet based on the gaze dwell data; and displaying the wine information and maturity of the target wine.

[0119] Specifically, by installing eye-tracking devices in the wine cabinet to capture users' gaze data, the system can identify the wines that users are interested in. By displaying the wine's information and maturity level, users can easily find the wines and understand their storage stage and whether they are most suitable for drinking. This further enhances the intelligence of the wine cabinet's wine management.

[0120] In some embodiments, a pressure sensor is provided at the bottom of each wine rack in the wine cabinet; the management method further includes: when wine to be stored is placed in the wine cabinet, detecting the storage location information of the wine to be stored through the pressure sensor; identifying the wine information of the wine to be stored through a built-in camera in the wine cabinet; and associating the storage location information and the wine information of the wine to be stored.

[0121] In this embodiment, after the user places the wine in the wine cabinet, the wine cabinet can identify the location information of the wine to be stored through a pressure sensor and identify the wine information of the wine to be stored through a camera inside the wine cabinet, and then store this information in association. This simplifies the wine storage process.

[0122] Combination Figure 5As shown, a device for managing wines in a wine cabinet includes: an acquisition module 501, a control module 502, an analysis module 503, and a recommendation module 504. The acquisition module 501 is configured to acquire the user's identity information when the user is in the target area in front of the wine cabinet. The control module 502 is configured to turn on the backlight of the wine cabinet and acquire an image of each wine in the cabinet. The analysis module 503 is configured to analyze the maturity of each wine based on the wine images. The recommendation module 504 is configured to recommend wines to the user based on the maturity of each wine and the user's identity information.

[0123] Combination Figure 6 As shown, this disclosure provides a wine management device 600 for wines in a wine cabinet. The wine management device 600 includes a processor 601 and a memory 602. Optionally, the device may further include a communication interface 603 and a bus 604. The processor 601, communication interface 603, and memory 602 can communicate with each other via the bus 604. The communication interface 603 can be used for information transmission.
