Identifying and recycling construction waste in an intelligent and automated way can not only effectively improve resource utilization, but also reduce negative impacts on the environment.

[0028] The technical solution of the present invention is further described below with reference to the accompanying drawings and through specific implementation methods.
[0029] Embodiment 1:
[0030] like Figure 1 As shown, a construction waste identification and recycling method provided in an embodiment of the present application includes steps S100 to S600.
[0031] Step S100: Acquire image data of construction waste, and segment the image data to obtain a plurality of image segments; wherein the image data includes images of construction waste.
[0032] In this step, a high-resolution camera device is used to take photos or capture real-time video of the piled-up construction waste, so as to obtain image data of the construction waste; specifically, image segmentation algorithms such as threshold segmentation, region growing or edge detection techniques can be used to segment the image data into multiple separate image segments for subsequent image processing and recognition.
[0033] For example, an edge detection algorithm is used to first identify the contours of different objects in a construction waste image, and then the image is cut using these contours to form separate image segments containing each independent construction waste object.
[0034] Step S200: performing image preprocessing on all image segments to obtain a preprocessed image of each image segment.
[0035] In this step, the image segments obtained after segmentation are preprocessed to enhance image quality and reduce interference; specifically, it may include operations such as adjusting brightness and contrast, noise reduction, standardization, normalization processing, and color space conversion.
[0036] For example, the image segments are grayed, and then a median filter is applied to remove image noise, followed by a histogram equalization to improve the image contrast, thereby obtaining a clearer, easier to analyze pre-processed image.
[0037] Step S300: extract image features from each preprocessed image to obtain image feature data of each preprocessed image.
[0038] In this step, image processing technology is used to extract feature data from the preprocessed image; specifically, various image feature extraction algorithms, such as SIFT, SURF, or HOG, can be used to extract information such as image shape, texture, color, and edge features.
[0039] For example, the SIFT algorithm is used to extract key points and corresponding descriptors of the construction waste image, focusing on the local features of the image to form specific image feature data of the preprocessed image.
[0040] Step S400: using a preset feature matching algorithm, match each image feature data with a preset construction waste feature library to obtain a plurality of matching feature data.
[0041] In this step, the extracted image feature data is compared and matched with the data in the feature library; specifically, a preset machine learning algorithm such as support vector machine (SVM), random forest or deep learning model is used to identify and match the corresponding construction waste type.
[0042] For example, a deep convolutional neural network (CNN) model is used for feature matching. After being trained with a large amount of construction waste image data, the model can improve the accuracy of feature data matching and the ability to identify different types of construction waste.
[0043] Step S500: Perform cluster analysis on all matching feature data to obtain a classification result for each matching feature data.
[0044] In this step, the matched feature data are further clustered; specifically, clustering algorithms such as K-Means, hierarchical clustering analysis or DBSCAN are used to group the matched feature data according to feature similarity to achieve automatic classification.
[0045] For example, the K-Means clustering algorithm is used to classify construction waste into different categories, such as concrete blocks, bricks, metal sheets, plastics, etc., based on the texture, color, and shape features in the matching feature data.
[0046] Step S600: Use all classification results to identify the construction waste image to obtain a recognition result, input the recognition result into a preset recycling decision system to make a recycling decision, obtain a recycling plan, and recycle the construction waste based on the recycling plan.
[0047] In this step, all classification results are used comprehensively to make the final identification of the construction waste images; specifically, the classification results are combined with the actual recycling needs, analyzed and processed by the recycling decision system, and a corresponding recycling plan is formulated.
[0048] For example, the recycling decision system evaluates the utilization value and treatment methods of each category of construction waste based on the identification results, and provides reasonable sorting and recycling strategies for reuse, resource processing or harmless disposal.
[0049] In this embodiment, the image data of construction waste is obtained and segmented to generate multiple image segments; then, each image segment is subjected to image preprocessing to generate a preprocessed image; then, image feature extraction is performed on each preprocessed image to obtain image feature data; each image feature data is matched with a preset construction waste feature library through a preset feature matching algorithm to generate matching feature data. These matching feature data are further subjected to cluster analysis to obtain classification results; finally, the construction waste images are identified using these classification results, and the identification results are output, which are input into a preset recycling decision system to form a recycling plan.
[0050] By utilizing image preprocessing and feature extraction methods, the accuracy of identifying the type of construction waste through image data is improved; furthermore, the feature matching algorithm plus the application of the construction waste feature library enables the identification process to accurately match the characteristics of various construction waste, and cluster analysis further optimizes the classification effect. The final automated identification and recycling decision-making system not only improves the speed of construction waste processing, reduces the labor intensity and error rate of manual sorting, but also improves the problems of being unable to process a large number of construction waste images in real time and having low accuracy in identifying different types of waste in actual application.
[0051] Embodiment 2:
[0052] In step S100, image data of construction waste is collected in real time based on a preset image acquisition device; wherein the image acquisition device includes a high-resolution camera, a laser radar, and a depth sensor.
[0053] By installing multiple image acquisition devices at the construction waste treatment site, comprehensive coverage of the on-site work area can be achieved; specifically, high-resolution cameras are used to image various types of construction waste, lidar is used to capture the spatial information of the waste to assist in segmentation, and depth sensors can perceive the volume and depth information of the construction waste.
[0054] For example, a high-resolution camera is installed above the conveyor belt to continuously photograph the construction waste passing through the conveyor belt, while the lidar is responsible for scanning the 3D contour data of the garbage. The data from both are fused to generate detailed image data.
[0055] The image data is preprocessed, and the preprocessed image data is input into a preset image segmentation algorithm. In the image segmentation algorithm, the preprocessed image data is segmented by image segmentation technology to obtain multiple image segments.
[0056] By automatically adjusting the image contrast and clarity and using Gaussian filtering to reduce image noise, a preset segmentation algorithm, such as a threshold-based segmentation algorithm, is further used to perform preliminary image segmentation processing; specifically, the segmentation algorithm is used to identify the boundaries of construction waste, thereby segmenting the continuous image into independent image segments containing individual construction waste.
[0057] For example, the software can automatically analyze the brightness differences in the image to separate construction waste from the background and other waste, and then use the region growing method to refine the segmentation results to obtain clearly defined garbage image fragments.
[0058] In step S200, brightness adjustment is performed on all image segments according to a preset image brightness adjustment model to obtain brightness-adjusted images.
[0059] By introducing an algorithm model to dynamically analyze the current brightness conditions of the image fragments and make real-time adjustments, the image is ensured to be in the optimal brightness state; specifically, the brightness level of each image fragment is adjusted to be within the preset standardized brightness range to improve image quality and the accuracy of subsequent processing.
[0060] For example, using a brightness adjustment method based on histogram analysis, for each image segment, its histogram is calculated and a stretching or compression technique is applied to adjust the brightness, thereby making the visual details of the image clearer.
[0061] The brightness-adjusted image is smoothed by Gaussian filtering to obtain a smoothed image and an image with reduced noise.
[0062] The Gaussian filter algorithm is used to eliminate random noise and small errors in the image and retain important structural features. Specifically, the Gaussian filter kernel is applied to the brightness-adjusted image to smooth the high-frequency noise of the image without affecting the clarity of the image edges and textures.
[0063] For example, appropriate Gaussian kernel parameters are set and the image is subjected to multiple Gaussian filtering processes until the noise is effectively suppressed while maintaining the authenticity and integrity of the image structure.
[0064] Edge detection is performed on the smoothed image and the image with reduced noise to obtain an edge detection image, and the contour of the image in the edge detection image is extracted to obtain a contour extraction image.
[0065] The structural edges in the image are highlighted by edge detection algorithms such as Canny or Sobel operators to facilitate contour extraction; specifically, each pixel point in the image after edge detection is traversed, the pixel points whose edge strength exceeds a specific threshold are marked, and these points are connected to form a continuous contour line.
[0066] For example, the Canny edge detection algorithm is implemented. The image is first processed using Gaussian blur to remove noise, and then the gradient and direction of the image are calculated. Finally, a clear garbage outline is determined and extracted through double threshold detection.
[0067] The contour extraction image is color enhanced by using histogram equalization to obtain a color enhanced image; the color enhanced image is scale transformed to obtain a scale change; and the color enhanced image is feature normalized based on the scale change to obtain a feature normalized image.
[0068] The contrast of the image is improved by the histogram equalization method, making the brightness distribution of the entire image more uniform; specifically, each pixel in the contour extraction image is reallocated according to its brightness value to form a color enhanced image, and then the size and resolution of these images are unified, and then the feature unification processing of the color enhanced image is implemented.
[0069] For example, histogram equalization is performed on the contour image to make the transition from dark areas to bright areas more natural, and then the image is uniformly scaled to a specified size to ensure consistency and comparability of subsequent processing.
[0070] The feature normalized image is refined through morphological operations to obtain a refined image and a structural image.
[0071] By applying morphological operations such as dilation, erosion or opening / closing operations, the structural characteristics of the image are further improved; specifically, the outline and internal details of the construction waste are highlighted through refinement processing, and irrelevant small blocks and spots are removed to obtain an image describing the morphological structure of the garbage.
[0072] For example, an erosion operation is first performed on the feature-normalized image to remove pixels at the object boundary, and then a dilation operation is performed to accurately refine the contours of the garbage, and finally a structural image with rich details that is beneficial for analysis is obtained.
[0073] Performing color space conversion on the refinement image and the structure image to obtain a color space image;
[0074] The color space image and the refined image are used to enhance the texture features of all the original image segments, and a preprocessed image of each image segment is obtained.
[0075] The color space conversion makes the image features more suitable for subsequent analysis and processing; specifically, the color representation of the image is changed, such as converting from RGB to HSV or Lab color space, to emphasize the characteristics of texture and color, and to enhance the texture characteristics of the original image fragment.
[0076] For example, an image is converted from RGB color space to HSV color space to better distinguish color changes and texture details in the image, and then this enhanced texture feature is applied to the original image segment to provide richer information for subsequent feature extraction.
[0077] In step S300, texture features are extracted from all pre-processed images according to the feature normalized images to obtain texture feature data and texture description data.
[0078] The texture information of the image is extracted through advanced image analysis techniques, such as gray-level co-occurrence matrix or local binary pattern; specifically, the texture characteristics of the preprocessed image are analyzed through these techniques and converted into numerical data and descriptive information that are easy to process later.
[0079] For example, the local binary pattern algorithm is used to encode the contrast relationship between each pixel of the preprocessed image and its surrounding pixels, generating feature data representing the texture of construction waste and metadata describing these features.
[0080] The texture feature data is classified and learned through a deep neural network to obtain classification feature data.
[0081] By training deep learning models, such as convolutional neural networks (CNNs), we learn the relationship between the texture features of images and different types of garbage. Specifically, based on a large number of labeled samples, we adjust the network parameters so that the network can effectively classify the input texture feature data and output the classification feature data of the corresponding category.
[0082] For example, a multi-layer deep convolutional network structure is designed and trained using a labeled construction waste image dataset so that the network can learn how to identify different categories of construction waste from texture features.
[0083] The geometric transformation is used to extract the geometric features of the classified feature data to obtain the geometric feature data and shape description data.
[0084] By calculating the geometric properties of different classification feature data, such as area, perimeter, compactness and other geometric indicators, the feature data describing the shape of construction waste are extracted; specifically, through these geometric transformations, the spatial position and size of garbage objects in the image are analyzed and measured to provide more complete shape description information.
[0085] For example, geometric transformation algorithms are used to calculate the contour characteristics of garbage objects in the image, such as polygon approximation or roundness measurement, and these geometric attributes are organized into shape description data.
[0086] The shape description data is vectorized to obtain vectorized feature data, and the original preprocessed image is object located based on the vectorized feature data to obtain object location data.
[0087] The complexity of shape features is simplified by converting shape description data into a vector form suitable for machine learning algorithms; specifically, key points that make a decisive contribution to the description of the object shape are extracted, and these key point data are vectorized to facilitate rapid identification of key parts that constitute the outline of construction waste in the image.
[0088] For example, by calculating the key points on the outline of construction waste and converting their coordinates into vectors, these vectorized data are used to locate objects and quickly identify the exact locations of separated construction waste objects in the image.
[0089] The object positioning data and the geometric feature data are used to perform object recognition on the original preprocessed image to obtain object recognition data, and the object recognition data is input into a preset feature comparison model to obtain image feature data of each preprocessed image.
[0090] Through object recognition technology, such as template matching-based recognition methods, the precise location and type of specific garbage objects in the image can be found; specifically, the object positioning data and geometric feature data are combined and compared with the preset feature comparison model to extract the positioning data with a high degree of match with the known garbage features, and finally obtain accurate image feature information.
[0091] For example, by using the shape template matching method, by comparing the shape features of various types of construction waste in the object positioning data and the feature comparison model, the object positioning points with a high degree of matching are found, thereby identifying the specific type of waste in the image and outputting the corresponding image feature data.
[0092] In step S400, a feature clustering algorithm is used to perform manifold learning on the image feature data to obtain local feature data, global feature data, and feature distribution data.
[0093] By utilizing manifold learning techniques, such as t-SNE or UMAP, the distribution of image feature data in multidimensional space is analyzed to discover the intrinsic structure of the data and the global and local similarities of image features; specifically, the multidimensional image feature data is mapped to a low-dimensional space in order to more intuitively understand the relationship and distribution pattern of junk features.
[0094] For example, the t-SNE algorithm is used to reduce the dimensionality of global feature data, so that similar features are clustered in a low-dimensional space, while different features are dispersed, so that a clear feature clustering distribution can be observed in the low-dimensional graph.
[0095] The local feature data is classified by support vector machine to obtain classification results and probability evaluation data, and the probability evaluation data is probabilistically fused with the global feature data to obtain probabilistic fusion data.
[0096] Through the support vector machine (SVM) algorithm, a decision interface is established to classify the local feature data according to their positions in the feature space; specifically, the optimal decision boundary is found according to the distribution of the local feature data, and classification is performed according to the decision interface, and the classification results and their corresponding probability evaluation data are generated. Then, the global feature data are comprehensively considered and data fusion is performed to obtain a more accurate and robust final classification result.
[0097] For example, an SVM classifier is trained to distinguish different types of construction waste feature vectors, and a probability score is provided for each predicted classification based on the distance from the decision boundary. The statistical probability model of the global feature data is then combined to obtain a more reliable prediction result.
[0098] The probability fusion data and the feature distribution data are subjected to pattern recognition to obtain pattern recognition data, and feature matching is performed on the pattern recognition data through a feature matching algorithm to obtain a matching result.
[0099] Through pattern recognition technology, the similarity between the recognition probability fusion data and the feature distribution data is compared to discover the classification rules of construction waste images; specifically, feature matching algorithms, such as Euclidean distance or cosine similarity, are used to compare the distance or direction between pattern recognition data and known feature distributions, and results with high matching scores are extracted to determine the feature classification of the image.
[0100] For example, the obtained probability fusion data is positioned in the space represented by the feature distribution data, and the distance measurement is used to evaluate its similarity with the cluster centers of each known pattern, and it is classified according to the pattern with the highest matching degree to obtain an exact matching result.
[0101] The matching results are input into a preset matching evaluation system, and a rule inference algorithm is used in the matching evaluation system to compare the similarity between the pattern recognition data and the feature data in the preset construction waste feature library to obtain a preliminary matching result.
[0102] By comparing the pattern recognition data with a large feature library, the most matching type of construction waste is identified; specifically, using rule reasoning algorithms, such as decision trees or fuzzy logic algorithms, the data in the matching evaluation system are subjected to detailed similarity analysis with the samples in the feature library to extract the closest matches and generate preliminary matching results.
[0103] For example, the extracted garbage image feature vector is input into a pre-trained decision tree model. The model compares the features of each category of construction waste in the feature library layer by layer according to each element of the feature vector, and gives the type of construction waste with the highest matching degree.
[0104] The preset similarity threshold is used to filter out feature data with similarity above the preset threshold in the preliminary matching results, and invalid matches below the similarity threshold are removed to obtain a matching feature data set. The matching feature data set is statistically analyzed and processed through multidimensional feature analysis to obtain cluster feature data and abnormal feature data.
[0105] By setting a similarity threshold, data with a low match degree compared with known construction waste characteristics are removed; specifically, the preliminary matching results are screened, and the data exceeding the similarity threshold is retained and regarded as valid. The matching feature data set obtained is processed using multidimensional statistical analysis to distinguish normal clustering features from abnormal features.
[0106] For example, if the similarity score between the matching feature data and a feature in the feature library exceeds the set threshold (such as 85%), it is considered a valid match and is included in the clustering feature data set; conversely, if the score is lower than the threshold, it is determined to be abnormal feature data and is excluded.
[0107] Based on a preset feature similarity calculation algorithm, similarity calculation is performed on the cluster feature data to obtain a similarity calculation result, and a feature comprehensive evaluation algorithm is used to comprehensively evaluate the similarity calculation result to obtain multiple valid matching feature data, and the multiple valid matching feature data are used as multiple matching feature data.
[0108] The similarity between different feature data is calculated through an efficient algorithm, and the similarity results are evaluated as a whole; specifically, a feature similarity calculation algorithm, such as cosine similarity calculation, is used to analyze each group of cluster feature data, and a feature comprehensive evaluation algorithm, such as weighted scoring method, is used to score each group of results, thereby extracting effective matching feature data with high scores.
[0109] For example, the similarity between the cluster feature data is calculated, and different weights are assigned according to the importance of the features. The weighted scoring method is used to evaluate the influence of each feature, and finally those features with high scores are screened out as valid data sets for determining matching.
[0110] In step S500, all matching feature data are standardized using a data standardization algorithm, and matching feature data of different scales are normalized to obtain standardized matching feature data.
[0111] Through standardization processing, all the obtained matching feature data are converted to the same scale to facilitate comparison and analysis between data; specifically, each feature data is converted into a dimensionless form using methods such as Z-score standardization or minimum-maximum standardization to ensure consistency in data processing.
[0112] For example, all matching feature data are Z-score standardized, the deviation of each feature value relative to its mean is calculated and divided by the standard deviation, and all data are mapped to the same standard deviation and mean range to ensure that the data are comparable in subsequent processing.
[0113] The dimension reduction algorithm is used to perform dimension reduction processing on the standardized matching feature data, reduce the dimension of the feature data, retain the main feature information, and obtain the matching feature data after dimension reduction.
[0114] Dimensionality reduction technology is used to reduce the complexity of data and improve algorithm efficiency. Specifically, dimensionality reduction methods such as principal component analysis (PCA) or linear discriminant analysis (LDA) are used to remove redundant and unimportant features and retain the main features that have an important impact on classification decisions.
[0115] For example, PCA is used to transform the obtained standardized matching feature data into a new feature space, retaining the feature components with the largest variance as the main features, while removing some unimportant components. The resulting dimensionality-reduced data set has a lower dimension and still contains sufficient information for effective classification.
[0116] The K-means clustering algorithm is used to perform preliminary clustering analysis on the feature data after dimensionality reduction, and the feature data after dimensionality reduction are assigned to multiple cluster centers to obtain several cluster feature data.
[0117] The K-means cluster analysis is used to assign the reduced-dimensional data points to the nearest cluster center, thereby classifying the feature data. Specifically, the number of clusters is set in advance, the distance between each feature data point and each cluster center is calculated, and mapped to the nearest cluster center, and gradually adjusted until each cluster center is stabilized.
[0118] For example, after determining the K value, the dimensionality-reduced matching feature data set is iteratively processed, and the data points are assigned to different cluster centers according to the Euclidean distance from each cluster center. The iterations are repeated until the clusters no longer change, thereby obtaining a series of cluster feature data representing different types of construction waste.
[0119] Each cluster feature data is classified based on a preset classification model to obtain a classification label for each cluster feature data, and the classification label for each cluster feature data is used as a classification result for each matching feature data.
[0120] Through a pre-trained classification model, such as a random forest or neural network model, a specific category label is assigned to each cluster feature data; specifically, the classification model is used to perform classification prediction on each data point in the cluster feature data set, and the predicted result label is combined with the original matching feature data as the final classification result.
[0121] For example, each cluster feature data obtained by the K-means algorithm is input into the previously trained random forest classifier, and the model is used to perform detailed analysis and label assignment on each cluster result. The data point of each cluster obtains an exact classification label based on the classification probability output by the model.
[0122] In step S600, all classification results are fused using a classification result fusion algorithm to obtain a fused classification result and a comprehensive classification result.
[0123] By aggregating the output results of multiple classification algorithms, more accurate and comprehensive garbage classification decisions can be obtained; specifically, ensemble learning or fusion methods, such as voting or stacking, are used to integrate and weigh different classification results to obtain the final fusion classification result.
[0124] For example, a multi-algorithm integration method is used to integrate the classification results of different models, and the final category label of each garbage category is determined according to the majority voting principle, thereby improving the accuracy and stability of the overall classification.
[0125] The fusion classification result is reconstructed through the image reconstruction algorithm to obtain the recognition image.
[0126] Image processing technology is used to combine the identified classification labels with the original image to reconstruct the recognition image containing the classification information. Specifically, image reconstruction algorithms are applied, such as reconstruction technology based on pixel-level segmentation, to add classification label information to the corresponding image area to generate the final recognition image, showing clear classification boundaries and logos.
[0127] For example, a bounding box of different colors is added to each image segment in the preprocessed image according to its classification label, and the reconstructed image clearly shows the type and location of each piece of construction waste.
[0128] The recognition image is compared and analyzed with the construction waste image to obtain the recognition result.
[0129] The accuracy and reliability of recognition are verified by analyzing the consistency and differences in features and structures between the recognized image and the original construction waste image; specifically, the shapes and features of each marked area in the recognized image are compared with the actual construction waste objects in the image to confirm the correctness of classification and recognition.
[0130] For example, compare the construction waste image with type identification obtained through image reconstruction with the actual construction waste distribution in the scene, check whether each classification mark is consistent with the characteristics of the real object, and record the classification success rate and misidentification as feedback on the recognition result.
[0131] Based on the recognition results, the recycling decision analysis of the construction waste images is carried out in combination with the preset recycling strategy database to obtain the recycling decision results.
[0132] Further analysis and decision-making are carried out on the identification results according to specific recycling strategies and relevant regulations; in particular, the treatment methods and resource values of different construction wastes provided by the recycling strategy database are used to formulate appropriate recycling or treatment plans for each type of construction waste.
[0133] For example, by utilizing the recycling policies and guidelines for different construction waste materials such as concrete, metal, and wood in the recycling strategy database and combining them with image recognition results, specific recycling processes and treatment methods can be developed for each type of waste, as well as subsequent resource utilization pathways, to form a practical recycling strategy plan.
[0134] The recycling decision results are input into a preset recycling decision model, in which recycling evaluation and recycling decision are performed based on the preset recycling strategy to generate a recycling plan.
[0135] By introducing professional recycling knowledge and optimization algorithms into the decision-making model, we ensure that the generated recycling plan is economical, effective and environmentally friendly. Specifically, by combining the cost-benefit analysis, environmental impact assessment and resource recovery value calculation functions in the recycling decision model, we comprehensively consider the identification results based on the recycling strategy and output the optimized recycling plan.
[0136] For example, based on the different types of construction waste identified, a recycling decision model is used to evaluate the processing costs, potential resource recovery value and environmental benefits of various types of waste. These factors are combined to design a set of specific operation paths and recycling methods to achieve the best economic and environmental results.
[0137] Carry out actual recycling operations on construction waste based on the recycling plan, and use automated recycling equipment and preset recycling routes to classify and recycle construction waste.
[0138] According to the recycling plan obtained, mechanization and automation technology are used to implement the specific recycling operations of construction waste; specifically, automatic sorting systems such as robotic arms and conveyor belts are used in combination with computer control programs to sort, transport and centrally process various types of construction waste according to predetermined paths and methods.
[0139] For example, according to the guidance in the recycling plan, a robotic arm is set up on the automatic sorting line to perform precise sorting based on the recognition image, and then different categories of construction waste are transported to designated processing areas or recycling containers, ultimately achieving effective and automated resource utilization of construction waste.
[0140] In this embodiment, by combining advanced image processing, machine learning and data analysis technologies, it is possible to accurately and efficiently identify and recycle construction waste from the acquired construction waste image data. First, various types of image acquisition devices are used to acquire construction waste images in real time, and then the image data is refined through multi-level preprocessing and feature extraction. Next, deep learning and clustering algorithms are used to effectively analyze and classify the feature data. Finally, an economical and environmentally friendly recycling plan is generated by combining the recycling strategy database and the recycling decision model, and the actual construction waste classification and recycling is carried out in conjunction with automated equipment. The whole process not only improves the recycling efficiency and reduces labor intensity, but also promotes the resource utilization of construction waste, which is conducive to environmental protection and sustainable development.
