The terminology used in the present application is for the purpose of describing particular embodiments only and is not intended to limit the scope of the present application.
In the description of the embodiments of the present application, unless otherwise indicated and defined, the term "connected" should be construed broadly, and for example, may be an electrical connection, may be a communication between two elements, may be a direct connection, or may be an indirect connection via an intermediary, and it will be understood by those skilled in the art that the specific meaning of the term may be understood according to the specific circumstances.

It is to be understood that the "first\second\third" distinguishing objects may be interchanged where appropriate such that the embodiments of the present application described herein may be implemented in sequences other than those illustrated or described herein.
Aiming at the technical problems, the technical conception of the method is to utilize deep learning and artificial intelligence technology to extract and classify the characteristics of the monitoring image of the doll so as to realize automatic detection of the surface defects of the doll, improve the production efficiency and quality level of the doll and ensure the rights and interests and safety of consumers.
Specifically, in the technical scheme of the application, firstly, a monitoring image of a doll to be detected is obtained. Here, the monitoring image may be used as basic data for doll quality inspection, thereby effectively analyzing and recognizing the doll surface.
In order to improve the quality and the analyzability of an image, in the technical scheme of the application, the monitoring image is subjected to image preprocessing to obtain a preprocessed monitoring image, wherein the image preprocessing comprises gray level conversion, image standardization, CLAHE and gamma correction. Specifically, the gray conversion means converting a color image into a gray image to reduce the dimension and complexity of the image while retaining the main information of the image; the image normalization is to normalize the pixel value of the gray level image to the [0,1] interval so as to eliminate the brightness difference between different images and enhance the contrast of the images; the CLAHE limits the self-adaptive histogram equalization of the contrast, so that the contrast of an image can be enhanced, and meanwhile, noise amplification and detail loss caused by excessive enhancement can be avoided; gamma correction is a method for adjusting the brightness of an image, which can strengthen details of a dark area and inhibit details of a bright area according to the perception characteristic of human eyes on the brightness, so that the image is clearer and more natural.
And then, carrying out image blocking processing on the preprocessed monitoring image to obtain a sequence of monitoring image blocks. That is, the preprocessed monitoring image is divided into a plurality of small image blocks. Therefore, the efficiency of image processing and deep learning analysis can be improved, the calculated amount and the memory occupation can be reduced, and the complexity and the cost of the system are reduced.
The sequence of surveillance image blocks is then passed through a ViT model containing an embedded layer to obtain a plurality of doll local image block feature vectors. The ViT model is a model in which a transducer is applied to image processing. The ViT model has the advantage that long-range dependencies between image tiles can be captured using the transducer's self-attention mechanism. Specifically, the ViT model contains an embedded layer that maps sequences of image blocks into fixed length vectors that are then fed into the transducer's encoder. The function of the embedding layer is to convert the original image block data into a form suitable for the transform process while preserving the information of the image block.
In consideration of the fact that the surface defects of the doll may be distributed at different parts of the doll, in the technical scheme of the application, the plurality of doll local image block feature vectors are arranged into a doll global feature matrix and then pass through a bidirectional attention mechanism module to obtain a classification feature matrix. Here, the overall information of the doll is represented by arranging the partial image block feature vectors of the doll into a global feature matrix of the doll. Also, the bi-directional attention mechanism module may utilize the concept of self-attention to enhance correlation between local regions. Specifically, the bidirectional attention module respectively calibrates the attention weights of the whole feature matrix from the horizontal direction and the vertical direction and acquires complex feature relations, so that local feature information can be completely acquired from the global features of the space.
Further, the classification feature matrix is passed through a classifier to obtain a classification result, wherein the classification result is used for indicating whether the doll to be detected has surface defects. The classifier can learn the characteristic distribution of normal and abnormal samples of the doll through a training data set, so that the new doll to be detected (namely, an input classification characteristic matrix) can be classified. In the technical scheme of the application, the classification labels of the classifier are of two types, namely 'the doll to be detected has surface defects' and 'the doll to be detected does not have surface defects', and the classifier determines which classification label the classification feature matrix belongs to through a soft maximum function. By the method, normal dolls and dolls with surface defects are distinguished, automatic detection of the surface defects of the dolls is achieved, the production efficiency and quality level of the dolls are improved, and the rights and the safety of consumers are guaranteed.
In the technical scheme of the application, when the classification feature matrix is obtained through the bidirectional attention mechanism module after the plurality of doll local image block feature vectors are arranged into the doll global feature matrix, the problem that when the convolutional neural network model containing the bidirectional attention mechanism performs feature extraction based on the attention weight mechanism in the row direction and the column direction, the overall feature distribution expression effect of the classification feature matrix is affected due to the fact that the internal image feature semantics of the doll local image block feature vectors are mixed with synthetic noise features caused by feature vector arrangement when the doll local image block feature vectors are spliced.
Therefore, the classification feature matrix is first converted into a square matrix by linear transformation, i.e. the number of rows and columns are the same, and then the square matrix is written as, for exampleVector spectral clustering agent learning fusion optimization is performed to obtain an optimized classification feature matrix, for example, expressed as +.>Here, the optimized classification feature matrix +.>The method comprises the following steps:wherein->Representing the square matrix->Is a line feature vector of (1), and->Is a distance matrix of distances between the respective vectors.
Here, when feature extraction is performed after feature vector stitching is performed on each doll local image block of the doll global feature matrix, the internal image feature semantics of each doll local image block feature vector is confused with the synthesized noise feature, so that the ambiguity of the demarcation between the meaningful quasi-regression image semantic features and the noise features is caused, and the vector spectral clustering agent learning fusion optimization utilizes the conceptual information of the association between the quasi-regression semantic features and the quasi-regression scene by introducing spectral clustering agent learning for representing the spatial layout and the semantic similarity between the doll local image block feature vectors, so that the latent association attribute between each doll local image block feature vector is subjected to implicit supervision propagation, thereby improving the overall distribution dependency of the doll global feature matrix serving as the synthesized feature, improving the overall feature distribution expression effect of the doll global feature matrix, and improving the accuracy of the classification result obtained by a classifier.
The application has the following technical effects: 1. a doll production management scheme, more particularly an automated doll surface defect detection scheme, is provided. 2. The scheme can realize automatic detection of the surface defects of the doll, improve the efficiency and accuracy of doll production management, reduce labor cost and resource consumption, and improve the quality and market competitiveness of the doll.
Fig. 1 is a schematic view of a scene of a method of managing production of a doll according to an embodiment of the present application. As shown in fig. 1, in this application scenario, first, a monitoring image (e.g., C as illustrated in fig. 1) of a doll to be detected (e.g., M as illustrated in fig. 1) is acquired; the acquired monitoring image is then input into a server (e.g., S as illustrated in fig. 1) where a doll 'S production management algorithm is deployed, wherein the server is capable of processing the monitoring image based on the doll' S production management algorithm to generate a classification result indicating whether the doll to be inspected has a surface defect.

As shown in fig. 3, in the network architecture, first, a monitoring image of a doll to be detected is acquired; then, performing image preprocessing on the monitoring image to obtain a preprocessed monitoring image, wherein the image preprocessing comprises gray level conversion, image standardization, CLAHE and gamma correction; then, carrying out image blocking processing on the preprocessed monitoring image to obtain a sequence of monitoring image blocks; then, passing the sequence of the monitoring image blocks through a ViT model comprising an embedded layer to obtain a plurality of doll local image block feature vectors; then, the feature vectors of the plurality of doll local image blocks are arranged into a doll global feature matrix, and then a classification feature matrix is obtained through a bidirectional attention mechanism module; then, carrying out feature distribution optimization on the classification feature matrix to obtain an optimized classification feature matrix; and finally, the optimized classification feature matrix is passed through a classifier to obtain a classification result, wherein the classification result is used for indicating whether the doll to be detected has surface defects or not.
Specifically, in step 110, a monitoring image of the doll to be inspected is acquired. Aiming at the technical problems, the technical conception of the method is to utilize deep learning and artificial intelligence technology to extract and classify the characteristics of the monitoring image of the doll so as to realize automatic detection of the surface defects of the doll, improve the production efficiency and quality level of the doll and ensure the rights and interests and safety of consumers.
Specifically, in the technical scheme of the application, firstly, a monitoring image of a doll to be detected is obtained. Here, the monitoring image may be used as basic data for doll quality inspection, thereby effectively analyzing and recognizing the doll surface.
Specifically, in step 120, the monitoring image is subjected to image preprocessing to obtain a preprocessed monitoring image, wherein the image preprocessing includes gray level conversion, image normalization, CLAHE and gamma correction. In order to improve the quality and the analyzability of an image, in the technical scheme of the application, the monitoring image is subjected to image preprocessing to obtain a preprocessed monitoring image, wherein the image preprocessing comprises gray level conversion, image standardization, CLAHE and gamma correction. Specifically, the gray conversion means converting a color image into a gray image to reduce the dimension and complexity of the image while retaining the main information of the image; the image normalization is to normalize the pixel value of the gray level image to the [0,1] interval so as to eliminate the brightness difference between different images and enhance the contrast of the images; the CLAHE limits the self-adaptive histogram equalization of the contrast, so that the contrast of an image can be enhanced, and meanwhile, noise amplification and detail loss caused by excessive enhancement can be avoided; gamma correction is a method for adjusting the brightness of an image, which can strengthen details of a dark area and inhibit details of a bright area according to the perception characteristic of human eyes on the brightness, so that the image is clearer and more natural.
Specifically, in step 130, the preprocessed monitoring image is subjected to image blocking processing to obtain a sequence of monitoring image blocks. And then, carrying out image blocking processing on the preprocessed monitoring image to obtain a sequence of monitoring image blocks.

The image blocking processing is performed on the preprocessed monitoring image to obtain a sequence of monitoring image blocks, and the method comprises the following steps: and uniformly partitioning the preprocessed monitoring image to obtain a sequence of monitoring image blocks, wherein each monitoring image block in the sequence of monitoring image blocks has the same size.
Specifically, in step 140, the sequence of surveillance tiles is passed through a ViT model containing an embedded layer to obtain a plurality of doll local tile feature vectors. The sequence of surveillance image blocks is then passed through a ViT model containing an embedded layer to obtain a plurality of doll local image block feature vectors.

It should be understood that since the transducer structure proposed by Google in 2017, a wave of hot surge is rapidly initiated, and for the NLP field, the self-attention mechanism replaces the conventional cyclic neural network structure adopted when processing sequence data, so that not only is parallel training realized, but also the training efficiency is improved, and meanwhile, good results are obtained in application. In NLP, a sequence is input into a transducer, but in the field of vision, how to convert a 2d picture into a 1d sequence needs to be considered, and the most intuitive idea is to input pixels in the picture into the transducer, but the complexity is too high.
While the ViT model can reduce the complexity of input, the picture is cut into image blocks, each image block is projected as a fixed length vector into the transducer, and the operation of the subsequent encoder is identical to that of the original transducer. However, because the pictures are classified, a special mark is added into the input sequence, and the output corresponding to the mark is the final class prediction. ViT exhibits quite excellent performance over many visual tasks, but the lack of inductive biasing allows ViT to be applied to small data sets with very much dependence on model regularization (model regularization) and data augmentation (data augmentation) compared to CNN (Convolutional Neural Network ).
Specifically, in step 150, the plurality of doll local image block feature vectors are arranged into a doll global feature matrix, and then passed through a bidirectional attention mechanism module to obtain a classification feature matrix. In consideration of the fact that the surface defects of the doll may be distributed at different parts of the doll, in the technical scheme of the application, the plurality of doll local image block feature vectors are arranged into a doll global feature matrix and then pass through a bidirectional attention mechanism module to obtain a classification feature matrix. Here, the overall information of the doll is represented by arranging the partial image block feature vectors of the doll into a global feature matrix of the doll. Also, the bi-directional attention mechanism module may utilize the concept of self-attention to enhance correlation between local regions. Specifically, the bidirectional attention module respectively calibrates the attention weights of the whole feature matrix from the horizontal direction and the vertical direction and acquires complex feature relations, so that local feature information can be completely acquired from the global features of the space.
Fig. 6 is a flowchart of a sub-step of step 150 in a method for managing the production of a doll according to an embodiment of the present application, as shown in fig. 6, after the plurality of doll local image block feature vectors are arranged into a doll global feature matrix, the doll global feature matrix is obtained by a bidirectional attention mechanism module, which includes: 151, pooling the doll global feature matrix along a horizontal direction and a vertical direction respectively to obtain a first pooling vector and a second pooling vector; 152, performing association coding on the first pooling vector and the second pooling vector to obtain a bidirectional association matrix; 153, inputting the bidirectional association matrix into a Sigmoid activation function to obtain a bidirectional association weight matrix; and 154, calculating the multiplication of the position points between the bidirectional association weight matrix and the doll global feature matrix to obtain the classification feature matrix.
The attention mechanism is a data processing method in machine learning, and is widely applied to various machine learning tasks such as natural language processing, image recognition, voice recognition and the like. On one hand, the attention mechanism is that the network is hoped to automatically learn out the places needing attention in the picture or text sequence; on the other hand, the attention mechanism generates a mask by the operation of the neural network, the weights of the values on the mask. In general, the spatial attention mechanism calculates the average value of different channels of the same pixel point, and then obtains spatial features through some convolution and up-sampling operations, and the pixels of each layer of the spatial features are given different weights.
Specifically, in step 160, the feature distribution of the classification feature matrix is optimized to obtain an optimized classification feature matrix. Fig. 7 is a flowchart of a sub-step of step 160 in the doll production management method according to an embodiment of the present application, as shown in fig. 7, performing feature distribution optimization on the classification feature matrix to obtain an optimized classification feature matrix, including: 161, converting the classification feature matrix into a square matrix through linear transformation, wherein the number of rows and the number of columns of the square matrix are the same; and 162, performing vector spectral clustering agent learning fusion optimization on the square matrix to obtain the optimized classification feature matrix.
In the technical scheme of the application, when the classification feature matrix is obtained through the bidirectional attention mechanism module after the plurality of doll local image block feature vectors are arranged into the doll global feature matrix, the problem that when the convolutional neural network model containing the bidirectional attention mechanism performs feature extraction based on the attention weight mechanism in the row direction and the column direction, the overall feature distribution expression effect of the classification feature matrix is affected due to the fact that the internal image feature semantics of the doll local image block feature vectors are mixed with synthetic noise features caused by feature vector arrangement when the doll local image block feature vectors are spliced.
Therefore, the classification feature matrix is first converted into a square matrix by linear transformation, i.e. the number of rows and columns are the same, and then the square matrix is written as, for exampleVector spectral focusingThe class proxy learning fuses the optimizations to obtain an optimized classification feature matrix, e.g., expressed as +.>Here, the optimized classification feature matrix +. >The method comprises the following steps: vector spectral clustering agent learning fusion optimization is carried out on the square matrix according to the following optimization formula so as to obtain the optimized classification feature matrix; wherein, the optimization formula is: />Wherein->Is the optimized classification feature matrix, +.>Is the square matrix, < >>Representing the individual row eigenvectors of the square matrix, and +.>Is a distance matrix consisting of the distances between every two corresponding row feature vectors of said square matrix,/>Is the transpose of the square matrix, +.>Is a transpose of the distance matrix, +.>Representing the Euclidean distance between the individual row feature vectors of the square matrix,/>Exponential operation representing a matrix, the exponential operation of the matrixCalculating a natural exponential function value representing the power of each position feature value in the matrix, < >>And->Respectively representing dot-by-location multiplication and matrix addition.
Here, when feature extraction is performed after feature vector stitching is performed on each doll local image block of the doll global feature matrix, the internal image feature semantics of each doll local image block feature vector is confused with the synthesized noise feature, so that the ambiguity of the demarcation between the meaningful quasi-regression image semantic features and the noise features is caused, and the vector spectral clustering agent learning fusion optimization utilizes the conceptual information of the association between the quasi-regression semantic features and the quasi-regression scene by introducing spectral clustering agent learning for representing the spatial layout and the semantic similarity between the doll local image block feature vectors, so that the latent association attribute between each doll local image block feature vector is subjected to implicit supervision propagation, thereby improving the overall distribution dependency of the doll global feature matrix serving as the synthesized feature, improving the overall feature distribution expression effect of the doll global feature matrix, and improving the accuracy of the classification result obtained by a classifier.
Specifically, in step 170, the optimized classification feature matrix is passed through a classifier to obtain a classification result, where the classification result is used to indicate whether the doll to be detected has a surface defect. Further, the classification feature matrix is passed through a classifier to obtain a classification result, wherein the classification result is used for indicating whether the doll to be detected has surface defects. The classifier can learn the characteristic distribution of normal and abnormal samples of the doll through a training data set, so that the new doll to be detected (namely, an input classification characteristic matrix) can be classified. In the technical scheme of the application, the classification labels of the classifier are of two types, namely 'the doll to be detected has surface defects' and 'the doll to be detected does not have surface defects', and the classifier determines which classification label the classification feature matrix belongs to through a soft maximum function. By the method, normal dolls and dolls with surface defects are distinguished, automatic detection of the surface defects of the dolls is achieved, the production efficiency and quality level of the dolls are improved, and the rights and the safety of consumers are guaranteed.
Fig. 8 is a flowchart of a sub-step of step 170 in the doll production management method according to an embodiment of the present application, as shown in fig. 8, the optimized classification feature matrix is passed through a classifier to obtain a classification result, where the classification result is used to indicate whether the doll to be detected has a surface defect, and the method includes: 171, expanding the optimized classification feature matrix into classification feature vectors according to row vectors or column vectors; 172, performing full-connection coding on the classification feature vector by using a plurality of full-connection layers of the classifier to obtain a coded classification feature vector; and 173, passing the encoded classification feature vector through a Softmax classification function of the classifier to obtain the classification result.
In summary, a method 100 for managing the production of a doll according to an embodiment of the present application is illustrated, which acquires a monitoring image of a doll to be inspected; the feature extraction and classification are carried out on the monitoring image of the doll by utilizing the deep learning and artificial intelligence technology so as to realize the automatic detection of the surface defects of the doll, improve the production efficiency and quality level of the doll and ensure the rights and interests and safety of consumers.
