[0030] The technical solution of the present application will be described in detail below with reference to the accompanying drawings and in combination with the implementation modes.

[0031] In a first aspect, an embodiment of the present application provides a smart trash can.

[0032] Figure 1 Schematic diagram of the structure of the intelligent trash can according to the preferred embodiment of the present application. The intelligent trash can includes a plurality of barrels, a plurality of barrel covers and a plurality of driving devices. The barrel is a structure for holding trash. Each barrel has a trash delivery port 14, such as Figure 1 As shown. The barrel body corresponds to the barrel cover one-to-one, and the barrel cover corresponds to the driving device one-to-one. Each barrel cover is installed on a barrel body and matches the garbage delivery port 14 of the barrel body. In the embodiment of the present application, the shape of the barrel cover is not limited, as long as the barrel cover can cover the garbage delivery port 14. In addition, the connection method between the barrel cover and the barrel body is not limited, as long as the barrel cover can be opened and closed. The driving device is used to drive the barrel cover when a driving instruction is received. For example, a button can be installed, and the garbage thrower presses the button, the button sends a driving instruction to the driving device, and the driving device drives the barrel cover, specifically, drives the barrel cover to open or close.

[0033] The plurality of barrels include a paper barrel 7, a plastic bottle barrel 10, a plastic product barrel 5, a metal barrel 6, a glass barrel 9, a fabric barrel 8, a hazardous waste barrel, a kitchen waste barrel 1, and a dry waste barrel 2. Figure 1 , Figure 2 , Figure 3 As shown. The paper barrel 7 is a barrel for holding paper waste; the plastic bottle barrel 10 is a barrel for holding plastic bottle waste; the plastic product barrel 5 is a barrel for holding plastic product waste, and the plastic product waste mentioned here refers to other plastic waste except plastic bottles in the plastic waste; the metal barrel 6 is a barrel for holding metal waste; the glass barrel 9 is a barrel for holding glass waste; the fabric barrel 8 is a barrel for holding old fabric waste; the hazardous waste barrel is a barrel for holding hazardous waste; the kitchen waste barrel 1 is a barrel for holding kitchen waste; and the dry waste barrel 2 is a barrel for holding dry waste.

[0034] In 2019, my country issued the latest revised "Marking for Classification of Domestic Waste" (GB / T19095-2019). Compared with the 2008 version, the scope of application of the new standard has been further expanded to cover the classified placement, collection, transportation and treatment of domestic waste. The categories of domestic waste are adjusted to four major categories: recyclables, hazardous waste, kitchen waste (also called "wet waste") and other waste (also called "dry waste"). In the implementation mode of this application, dry waste also refers to other waste in the four major categories, and kitchen waste also refers to wet waste.

[0035] In the implementation mode of the present application, on the basis of the four categories (recyclables, kitchen waste, other waste, hazardous waste), recyclables are further subdivided into 6 categories, including: paper, plastic bottles, plastic products, metals, glass and old fabrics. By strengthening the refined management of domestic waste, it is beneficial to reduce the back-end sorting pressure and improve the resource recycling rate.

[0036] In the implementation mode of the present application, plastics are subdivided into plastic bottles and other plastic products, which can be more in line with the recycling process. Plastic bottles and other plastic products have different recycling and reuse methods and different recycling processes; the recycling value can be improved. The recycling value of plastic bottles and other plastic products is different; the pollution risk can be reduced and the recycling quality can be improved. The pollution risk and the quality of recycled materials of plastic bottles and other plastic products are different. Mixing them together for recycling will increase the pollution risk and reduce the recycling quality. Separately classifying plastic bottles can simplify the subsequent recycling process and improve recycling efficiency. For recycling agencies, handling plastic bottles separately is conducive to bulk recycling and processing, and improves economic benefits.

[0037] In addition, parts of the barrel can be refined, e.g. Figure 1 As shown, the hazardous waste barrel body includes an expired medicine barrel body 11, an electronic waste barrel body 12, a lamp barrel body 3, and a cosmetic barrel body 4. Among them, the expired medicine barrel body 11 is a barrel body for holding expired medicines, the electronic waste barrel body 12 is a barrel body for holding electronic waste, the lamp barrel body 3 is a barrel body for holding lamp waste, and the cosmetic barrel body 4 is a barrel body for holding cosmetic waste.

[0038] Optionally, in the embodiment of the present application, the distribution of the multiple barrels can be determined according to specific circumstances, and there is no limitation on this.

[0039] Optionally, in the embodiment of the present application, the capacity of each barrel can be determined according to specific circumstances, and there is no limitation on this. For example, the capacity of the barrel can be determined according to the predicted amount of garbage generated. The capacity of different barrels is determined according to the predicted amount of different types of garbage.

[0040] In order to accurately predict the amount of garbage generated, a model for predicting the amount of garbage generated is constructed, where the population includes permanent residents and tourists (or foreign population). Assume that the amount of garbage generated by permanent residents is a constant C, and the amount of garbage generated by tourists is a power function of the number of tourists P. Assume that P is a function of time P(t), and construct a calculus formula for predicting the amount of garbage generated with the population P as a function. Where t represents time. For example, the unit of t can be days.

[0041] 1) The amount of garbage generated per unit time by permanent residents

[0042] The amount of garbage generated by permanent residents Y C is a constant C, indicating that the amount of garbage generated by permanent residents per unit time is fixed, and Y C =C.

[0043] 2) The amount of garbage generated by tourists per unit time

[0044] The number of tourists is P(t), and the amount of garbage generated by tourists is in a power function relationship with P(t), which can be expressed as: Y L (t) = k·P(t) n Among them, k is the proportional constant, which represents the amount of garbage generated by each tourist per unit time; n is the power exponent, which describes the relationship between the amount of garbage generated by the tourist population and the population; P(t) is the number of tourists at time t.

[0045] 3) Total waste generation formula

[0046] The total amount of garbage generated per unit time is the sum of the garbage generated by permanent residents and tourists: Y z (t) = Y C +Y L (t). Substituting into the previous formula, Y z (t) = C + k·P(t) n .

[0047] To find the total amount of garbage generated during a period of time, we can integrate the above formula. Suppose we want to calculate the total amount of garbage generated from time t1 to t2: This model can be used to predict the amount of garbage in different time periods, and is particularly suitable for considering the impact of factors such as tourist seasons or holidays on garbage generation.

[0048] 1) Prediction of kitchen waste production. If the number of tourists P(t) is exponentially growing, and P(t) can be expressed as: P(t) = P0 n ·e nαt Among them, P0 is the number of tourists at the initial time t0; α is the population growth rate; and n is the power exponent.

[0049] The total amount of garbage generated per unit time is: Y z (t) = C + k·P0 n ·e nαt .

[0050] The amount of kitchen waste generated per unit time is: Y y (t) = r·(C+k·P0 n ·e nαt )

[0051] The total amount of kitchen waste between time t1 and t2:

[0052]

[0053]

[0054] Among them, C is the amount of garbage generated per unit time by the permanent population; k·P0 is the initial garbage generation coefficient of the tourist population; nα is the parameter that controls the exponential growth rate; r is the proportion of kitchen waste in the total garbage; t1 to t2 is the time interval for calculating the amount of kitchen waste.

[0055] 2) Calculation of the amount of recyclable garbage and other garbage generated. The calculation of the amount of recyclable garbage and other garbage generated is the same as that of kitchen waste. For each type of garbage, determine its ratio to the total amount of garbage, then determine the amount of garbage generated per unit time, and then integrate the time to obtain the amount of garbage generated in a certain time interval.

[0056] The technical solution provided in the implementation mode of the present application proposes a garbage production prediction model based on the delivery data and historical garbage generation data, which can dynamically predict the future garbage production according to time, region and population flow. This prediction helps to rationally configure garbage collection equipment and transportation resources, reduce garbage accumulation and transportation costs, and improve the efficiency of sanitation operations. Combined with the garbage production prediction model and real-time monitoring data, the system can dynamically adjust the garbage collection and transportation plan, optimize resource allocation, and avoid resource waste. At the same time, it can also warn of possible excessive garbage delivery, arrange for timely removal, and ensure environmental hygiene.

[0057] Optionally, in the embodiment of the present application, the position of the garbage inlet 14 can be determined according to specific circumstances, and there is no limitation on this.

[0058] like Figure 1As shown in Figure 2, the garbage disposal ports 14 of the kitchen waste barrel 1, the dry garbage barrel 2, the lamp barrel 3, the cosmetics barrel 4, the plastic product barrel 5, the metal barrel 6, the paper barrel 7, and the fabric barrel 8 are arranged above the barrel body, that is, the side of the barrel body away from the ground; the garbage disposal ports 14 of the glass barrel body 9, the plastic bottle barrel body 10, the expired medicine barrel body 11, and the electronic waste barrel body 12 are arranged in front of the barrel body, that is, the side of the barrel body facing the garbage thrower.

[0059] In the implementation mode of the present application, by predicting the amount of garbage generated, not only can the size of the barrel be designed more accurately, but also sufficient transportation vehicles can be equipped to improve the efficiency of garbage resource utilization.

[0060] Optionally, in the implementation mode of the present application, the smart trash can further includes: a communication device, a control device and a display device. The communication device is used to receive the garbage category of the garbage from the server; the control device is used to control the display device to display the garbage category; and the display device is used to display the garbage category. Figure 5 As shown, the garbage category is displayed.

[0061] Optionally, in the implementation manner of the present application, the server may be a cloud server.

[0062] By displaying the categories of garbage being disposed of and providing visual guidance for garbage disposal, garbage disposers can classify and deliver garbage more intuitively and accurately, reducing the chances of misclassification and incorrect disposal, improving the accuracy of garbage disposal, and enhancing the reliability of smart trash cans.

[0063] Optionally, in the implementation manner of the present application, the server may determine the garbage category based on the options for distinguishing garbage categories displayed by the garbage thrower on the display device; or may also determine based on the image of the thrown garbage.

[0064] Optionally, in the implementation manner of the present application, the communication device, the control device and the display device may be arranged at locations according to specific circumstances. Figure 1 As shown, a smart terminal is arranged between the paper barrel 7 and the fabric barrel 8, and the display screen 13 of the smart terminal is the display device described in the embodiment of the present application. In addition, the smart terminal also includes a communication device and a control device.

[0065] Communication equipment can be a communication medium that can transmit data to a server. For example, communication equipment can be a 4G communication module, a wireless communication module, and a network interface module. The 4G communication module is an important carrier for connecting to cloud servers and is one of the core components for terminal devices to access the Internet of Things. The 4G communication module has the characteristics of fast communication speed, wide network spectrum, better cost performance, and flexible communication. The wireless communication module is the information entrance for various smart terminals to access the Internet of Things, and can achieve no broken packets within the signal coverage range; the wireless communication module can extend the communication distance, expand the coverage radius, increase the network access capacity, etc., and has good adaptability and scalability. Users can connect to the network through the network cable interface module.

[0066] The control device may be any device capable of performing control operations, for example, may be a programmable logic controller (PLC).

[0067] The display device may be any device capable of displaying content. For example, the display device may be a display screen.

[0068] Optionally, in the embodiment of the present application, the control device is further used to send a driving instruction to a target driving device, wherein the target driving device is a driving device for driving a barrel cover corresponding to the garbage category. The barrel cover corresponding to the garbage category is a barrel cover of a barrel body for holding garbage of the determined garbage category. The control device sends a driving instruction to the driving device to control the driving barrel cover, which can simplify the operation of the garbage thrower and improve intelligence and practicality.

[0069] In the embodiment of the present application, the driving instruction may be an instruction to drive the barrel lid to open, or an instruction to drive the barrel lid to close. For example, after receiving the garbage category sent by the server, an instruction to drive the barrel lid to open is sent to the driving device so that the barrel lid is opened, so that the garbage thrower can put the garbage. For another example, after the cumulative time after sending the instruction to drive the barrel lid to open reaches a preset time, an instruction to drive the barrel lid to close is sent to the driving device so that the barrel lid is closed.

[0070] Optionally, in the embodiment of the present application, the driving device may include a motor 15, a rotating shaft 16, a gear and a motor controller, such as Figure 4 As shown, the gear and motor controller are not shown. Figure 4 The driving device provided in the embodiment of the present application is introduced as an example. It should be noted that the driving device for driving any barrel cover can be understood by referring to the following content.

[0071] The motor 15 is mounted on the barrel body 19. The specific installation position of the motor 15 can be determined according to the specific situation, for example, it can be determined according to the position of the garbage delivery port, that is, according to the position of the barrel cover. Figure 4As shown, the barrel cover 18 blocks the garbage delivery port, which is located at the top of the barrel body 19 away from the ground, and the motor 15 is close to the barrel cover 18, and the motor 15 is fixed on the inner side of the top of the barrel body 19. The rotating shaft 16 is installed on the barrel cover 18. The output shaft of the motor 15 is connected to the gear, and the gear is engaged with the rotating shaft 16, and the motor 15 drives the rotating shaft 16 through the gear. The motor controller is used to drive the motor 15 when receiving a driving instruction, and the motor 15 drives the rotating shaft 16 through the gear transmission, and the rotating shaft 16 drives the barrel cover 18 to open or close.

[0072] Optionally, in the embodiment of the present application, the driving device may further include a spring and / or a limit switch 20. One end of the spring is connected to the barrel body and the other end is connected to the barrel cover. Figure 4 As shown, one end of the spring 17 is connected to the barrel body 19 and the other end is connected to the barrel cover 18. The spring 17 is located above the barrel cover 18, one end of the spring 17 is fixed to the inner side of the barrel body 19, and the other end is connected to the barrel cover 18. The spring 17 provides auxiliary power when the barrel cover 18 is opened, reducing the burden on the motor 15.

[0073] The limit switch 20 detects whether the bucket cover 18 reaches the preset position; when the bucket cover 18 reaches the preset position, an arrival indication message is issued to control the motor 15 to stop working. The arrival indication message is used to indicate that the bucket cover 18 has reached the preset position. The preset position can be determined according to specific circumstances. For example, the preset position can include a position where the bucket cover 18 is fully opened and / or fully closed. In this way, by setting the limit switch, energy consumption can be reduced and energy can be saved.

[0074] Optionally, the limit switch 20 sends the arrival indication information, which may be sent to the motor controller, and the motor controller controls the motor 15 to stop working according to the arrival indication information. Alternatively, the limit switch 20 sends the arrival indication information to the control device, the control device sends an instruction to the motor controller to stop the motor 15, and the motor controller controls the motor 15 to stop working according to the received instruction.

[0075] Optionally, in the embodiment of the present application, the limit switch 20 is installed at a position close to the connecting hinge for connecting the bucket cover 18 and the bucket body 19, which is located inside the edge of the bucket cover 18. The preset position includes the position when the bucket cover 18 is fully opened and fully closed. When the bucket cover 18 is fully opened and fully closed, the limit switch 20 triggers a signal.

[0076] Optionally, in the embodiment of the present application, the smart trash can may further include a photographing device. The photographing device is used to photograph the garbage image of the garbage. For example, the photographing device may be a camera. Optionally, in the embodiment of the present application, the camera may be a binocular camera.

[0077] The control device is also used to control the communication device to transmit the garbage image to the server. The server determines the garbage category of the garbage to be thrown based on the garbage image, and then transmits the determined garbage category to the control device via the communication device.

[0078] Optionally, in the implementation manner of the present application, the installation position of the shooting device can be determined according to the specific situation, as long as it can meet the shooting requirements. For example, the camera can be installed in the same position as the smart terminal.

[0079] Optionally, in the implementation mode of the present application, the control device is also used to control the communication device to transmit identity information to the server. The server logs into the account of the garbage dumper based on the identity information it receives. Specifically, based on the identity information, the garbage dumper is authenticated; if the identity authentication is passed, the garbage dumper's account is logged in.

[0080] For example, the identity information may be the facial information of the garbage dumper. The camera captures the garbage dumper, obtains the facial information, and transmits the acquired facial information to the control device. The control device transmits the facial information to the server via the communication device. The server verifies the facial information; if the verification is successful, the server logs in to the account corresponding to the facial information.

[0081] Optionally, in the implementation manner of the present application, the shooting device may be a binocular camera. The binocular camera is more rigorous and faster in acquiring facial information than a simple camera, and the probability of being cracked is much lower.

[0082] For example, the identity identification information can also use WeChat account information. For example, the garbage disposer uses WeChat to scan the QR code displayed by the display device, and the control device obtains the WeChat account information and controls the communication device to transmit the WeChat account information to the server. The server verifies the WeChat account information and logs in to the account corresponding to the WeChat account information if the verification passes. In addition, when transmitting the WeChat account information, the control device also controls the communication device to transmit the identification information of the smart trash can to the server. When verifying the WeChat account information, the server also verifies the identification information of the received smart trash can.

[0083] For another example, the identity information may also be IC card information. The smart trash can includes an IC card swiping device. The garbage disposer swipes the card in the swiping area, and the IC card swiping device transmits the acquired IC card information to the control device. The control device acquires the IC card information and transmits it to the server via the communication device. The server verifies the user identity information bound to the IC card information, and logs in to the account corresponding to the IC card information if the verification is successful. In addition, when transmitting the IC card information, the control device also controls the communication device to transmit the identification information of the smart trash can to the server. When verifying the user identity information bound to the IC card, the server also verifies the received identification information of the smart trash can.

[0084] By logging into the account, the garbage disposal behavior of the garbage disposer can be recorded and the information can be fed back to the backend system. This method can effectively supervise and motivate residents to correctly sort garbage, provide real-time disposal guidance, and further improve classification accuracy.

[0085] Optionally, in the implementation manner of the present application, the display device may display the identity authentication method. Figure 6 As shown, the identity authentication methods may include "face recognition", "QR code recognition" and "IC card recognition". The garbage disposer selects an identity authentication method on the display device, then controls the device to obtain the identity identification information corresponding to the selected identity authentication method, and controls the communication device to transmit the obtained identity identification information to the server.

[0086] Optionally, in the embodiment of the present application, the smart trash can may also include an auxiliary counting device. The auxiliary counting device is installed on the plastic bottle barrel, and the auxiliary counting device is used to assist the control device in counting the number of plastic bottles placed in the plastic bottle barrel. The control device counts the number of plastic bottles placed in the plastic bottle barrel based on the auxiliary counting device and controls the communication device to transmit the counted number to the server. The server returns a reward to the account of the garbage thrower based on the counted number it receives, for example, it may be a point reward or a cash reward. Optionally, in the embodiment of the present application, the auxiliary counting device is installed at the garbage placement port of the plastic bottle barrel.

[0087] In view of the characteristics of bottle garbage, an auxiliary counting device is designed at the garbage delivery port of the plastic bottle barrel. When the garbage thrower delivers bottles, the auxiliary counting device will help count the number of bottles delivered by the garbage thrower; the counted number is reported to the background (server) via the communication device, and the background returns a certain amount of points (or cash) reward to the garbage thrower's account.

[0088] Optionally, in an embodiment of the present application, the auxiliary counting device includes a photoelectric sensor. The photoelectric sensor is installed at the garbage inlet. The photoelectric sensor is used to detect whether an object passes through the garbage inlet. When an object is detected passing through the garbage inlet, a signal is transmitted to the control device. The control device counts the number of times the signal is received, and the number of times counted is the number of plastic bottles.

[0089] Optionally, in the embodiment of the present application, the server may also count the number of garbage images identified as plastic bottles or count the number of plastic bottle barrels whose lids are opened, thereby obtaining the number of plastic bottles.

[0090] Optionally, in the embodiment of the present application, the smart trash can further includes an auxiliary counting device. The auxiliary counting device is installed on the glass barrel body, and the auxiliary counting device is used to assist the control device in counting the number of times glass garbage is delivered into the glass barrel body. The control device is also used to count the number of times glass garbage is delivered into the glass barrel body based on the auxiliary counting device and control the communication device to transmit the counted number of times to the server.

[0091] The server returns a reward to the account of the garbage thrower based on the number of times it counts, for example, it can be a point reward or a cash reward. Optionally, in an embodiment of the present application, the counting device is installed at the garbage outlet of the glass barrel.

[0092] In view of the characteristics of glass garbage, an auxiliary counting device is designed at the garbage delivery port of the glass barrel. When the garbage thrower delivers glass, the auxiliary counting device helps count the number of times the garbage thrower delivers glass and reports it to the backend (server). The server returns a certain amount of points (or cash) to the garbage thrower's account.

[0093] Optionally, in an embodiment of the present application, the auxiliary counting device includes a photoelectric sensor. The photoelectric sensor is installed at the garbage delivery port. The photoelectric sensor is used to detect whether an object passes through the garbage delivery port. When an object is detected passing through the garbage delivery port, a signal is transmitted to the control device. The control device counts the number of times the signal is received, and the number of times counted is the number of times the glass garbage is delivered. Among them, if the interval between the reception time of two adjacent signals is less than the preset time interval, it is considered as one delivery of glass garbage.

[0094] Optionally, in the implementation manner of the present application, a camera for assisting in counting can be provided on the glass barrel body, which is marked as a counting camera. The counting camera can take pictures of the garbage delivery port. The counting images taken by the counting camera are transmitted to the control device, and the control device transmits the received counting images to the server via the communication device. The server counts the counting images it receives, and the number obtained is the number of times the glass garbage is delivered. In addition, the server also performs feature comparison on the counting images received continuously within a preset time interval, for example, comparing features such as color, texture, and transparency. If the features are similar, it is determined that they belong to the same piece of glass and are only counted as one delivery.

[0098] A weighing device is installed inside the barrel to intelligently weigh the garbage delivered each time, and uses digital signals to process information and provide timely feedback to the server. The server returns corresponding points or cash to the garbage disposer based on the redemption rules set by the system, with higher accuracy and greater durability.

The infrared probe or ultrasonic probe is used to detect whether the barrel body is full, and sends full barrel indication information to the control device when the barrel body is detected to be full; when the control device receives the full barrel indication information, it controls the full barrel indication device to indicate. For example, the full barrel indication device is an indicator light, and the indicator light can be controlled to light up or flash. In addition, the control device also transmits the full barrel indication information to the server, so that the server notifies relevant personnel to handle the garbage quickly and timely. After receiving the full barrel prompt, the server can dispatch sanitation personnel and vehicles to the site for timely processing and quick response.

[0102] For example, an infrared probe is installed on the top of the barrel, emitting infrared rays vertically downward to measure the distance from the garbage surface to the probe. When the distance is less than a set threshold (such as 10% of the distance from the bottom of the barrel to the probe), the barrel is determined to be full.

[0103] Optionally, in an embodiment of the present application, a full bucket indication device is installed at the garbage delivery port.

[0127] In a second aspect, the embodiments of the present application further provide a smart garbage system, which includes: the smart garbage bin and the server described in the above embodiments.

[0128] Optionally, in the implementation manner of the present application, the server may determine the category of the garbage to be thrown, including the following contents.

[0129] Obtain a garbage image of the disposed garbage. Specifically, obtain the garbage image via a communication device. Based on the acquired garbage image, determine a first garbage feature, wherein the first garbage feature is a garbage feature of the disposed garbage, and the garbage feature includes at least one of the following: shape feature, color feature, and texture feature. Based on the determined first garbage feature and a preset garbage category library, determine the category of the disposed garbage, wherein the preset garbage category library indicates a corresponding relationship between a second garbage feature and the category, wherein the second garbage feature is a garbage feature determined by the category, that is, the category of the second garbage feature is known.

[0130] Optionally, in the embodiment of the present application, when the garbage feature includes at least two of shape features, color features, and texture features, determining the category of the disposed garbage based on the determined first garbage feature and a preset garbage category library may include the following: determining the similarity between a first feature vector and a second feature vector, wherein the first feature vector corresponds to the first garbage feature and the second feature vector corresponds to the second garbage feature; and determining the category of the disposed garbage based on the determined similarity.

[0131] Combine the following Figure 8 The garbage classification identification provided in the embodiments of the present application is exemplified.

[0132] Take a picture of the garbage. When the garbage collector puts the garbage into the built-in camera of the smart trash bin, the camera takes a picture of the garbage.

[0133] Preprocess the junk images. After capturing the junk images, they are transmitted to the server. The server preprocesses the junk images, which may include noise reduction, cropping, scaling, etc., to ensure that the quality of the junk images is suitable for further analysis.

[0134] Feature extraction: Extract garbage features from garbage images, where garbage features include color features, shape features, texture features, and other information, and extract information useful for classification from garbage images.

[0135] Shape features are very important in garbage sorting, especially when identifying objects such as paper, metal objects, etc. The shape features may include at least one of the following: contour, geometric moment, aspect ratio, complexity.

[0136] Regarding contours, edge detection algorithms are used to find the edges of objects and separate the contours of objects. The external contours of objects are extracted and shape features such as area, aspect ratio, and roundness are analyzed. The smallest outer bounding shape of an object is found to help distinguish the shape of the object, such as identifying the folded edge of paper.

[0137] Perform shape matching and calculate geometric moments. Identify objects in an image by comparing it with a pre-stored template image. For example, when identifying a metal can, you can find the specific shape of the object through template matching. By calculating the geometric moments of the shape, you can obtain features that describe the shape of the object. These features are independent of the rotation, translation, and scaling of the object, and can effectively identify the shape of the object.

[0138] Calculate aspect ratio and complexity. After obtaining the outline, determine the shape of the object by calculating the aspect ratio of the outline. For example, the aspect ratio of a plastic bottle is different from that of a piece of paper, which can be used to distinguish the two. Calculate the complexity of the edge of the object to determine whether it is a simple geometric shape or an object with more complex curves.

[0139] Color features are an important distinguishing factor in garbage classification, wherein the color features may include at least one of the following: color histogram and color statistical features.

[0140] For the color histogram, extract the histogram of the red, green, and blue channels in the garbage image to reflect the color distribution of the image. For example, plastic bottles usually have a certain degree of transparency or color, while the color of paper may be more diverse. Extracting features such as hue, saturation, and value in the HSV color space is very effective in distinguishing different types of garbage. For example, the colors of green bottles, red bottles, and paper can be separated through HSV.

[0141] For color statistics, the mean and standard deviation of the color in an image or region are calculated to help distinguish the color characteristics of objects. Converting images from RGB space to other color spaces (such as LAB, YCbCr, etc.) can better separate the color characteristics of different substances, especially in low-light environments.

[0142] Texture features are helpful for identifying the surface structure or material of an object, especially for garbage such as paper, fabric, metal, etc. The texture features can be obtained based on at least one of the following: gray level co-occurrence matrix (GLCM), wavelet transform, and directional features.

[0143] GLCM is one of the most commonly used texture feature extraction methods. It extracts texture features by calculating the co-occurrence relationship between pixel grayscale values ​​in an image. Texture features can include contrast, homogeneity, and entropy. Contrast describes the degree of change in pixel grayscale values, which helps to identify rough or delicate surfaces. Homogeneity reflects the uniformity of texture within the image area and can distinguish objects with smooth surfaces such as paper. Entropy describes the complexity of the texture and is suitable for complex textures (such as cloth or multi-layered garbage).

[0144] Wavelet transform is used to extract texture features of images from different scales, and is particularly suitable for extracting detail information of irregular surfaces (such as paper, fabric, etc.).

[0145] Directional features, using Gabor filters to perform directional texture analysis, can extract texture features in different directions in the image. It is particularly effective for surface features such as metal surfaces and fabrics.

[0146] Image database comparison. Compare the extracted garbage features with the features of known categories of garbage stored in the database. The database contains multiple garbage classification image libraries, and each garbage category corresponds to a set of feature data.

[0147] By comparing the extracted garbage features with the known categories of garbage features stored in the database, the garbage category can be identified.

[0148] (1) Review of image feature extraction. In the previous feature extraction step, the system extracts garbage features from the input garbage image through different algorithms (such as color, shape, texture, etc.). These extracted garbage features are usually represented in the form of a feature vector, marked as the first feature vector, and used to compare with the feature data in the database.

[0149] (2) Image database construction and storage. The image database is a collection of feature data of various known categories. Each garbage category has a corresponding feature vector in the database, marked as the second feature vector. These feature vectors are generated from the labeled images through machine learning or manual feature extraction methods. The contents of the database include: garbage category labels, garbage category features, and the corresponding relationship between the two. Garbage category labels, such as "plastic bottles", "paper", "metal", etc. Garbage category features, feature vectors extracted from each garbage category. For example, the feature vector corresponding to plastic garbage has a color mean of red + transparent, shape: long cylinder, and texture: smooth. The feature vector corresponding to paper garbage has a color mean of white, shape: rectangular, and texture: rough. The feature vector corresponding to metal garbage has a color mean of silver, shape: irregular, and texture: smooth and reflective.

[0150] (3) Feature matching algorithm. Feature matching is a step to determine the garbage category by matching the feature vectors in the image database. Euclidean distance is a commonly used method to calculate the similarity between two points. For each new image, the system calculates the Euclidean distance between its feature vector and the feature vectors of each category in the database. The smaller the distance, the more similar it is. The system will then select the category with the smallest distance as the predicted category for the image.

[0151] Calculation formula: Among them, x i and i are the i-th elements of the two eigenvectors respectively.

[0152] Garbage category output. By comparing with the images in the database, the most matching garbage category is determined and the identification result (such as "plastic bottle", "paper", "metal", etc.) is output. The server transmits the determined garbage category to the control device, which can control the display device to display it.

[0155] In addition, the various implementation modes of the present application may be arbitrarily combined, and as long as they do not violate the concept of the present application, they should also be regarded as the contents disclosed by the present invention.
