The present disclosure relates to the field of detection technologies, and more particularly, to a method and device for detecting defect of a meal box, a server, and storage medium.
With the rapid development of Internet and communications, catering industry has flourished, the demand for meal boxes is increased, and the quality detection of meal boxes is important.
Embodiments of the present disclosure provide a method for detecting defect of a meal box, including: receiving a detection request including an image of the meal box sent by a user terminal, and performing defect recognition based on the image of the meal box and a defect detection model in response to the detection request. The image of the meal box is obtained by an image acquirer of the user terminal.
Embodiments of the present disclosure provide a method for detecting defect of a meal box, including: acquiring an image of the meal box by an image acquirer; generating a detection request including the image of the meal box; and transmitting the detection request to a server. The detection request is configured to instruct the server to perform defect recognition based on the image of the meal box and a defect detection model in response to the detection request.
Embodiments of the present disclosure will be described in detail below with reference to the accompanying drawings and embodiments. It should be understood that, the specific embodiments described herein are only used to explain the present disclosure rather than to limit the present disclosure. In addition, it should also be noted that, for convenience of description, only part but not all structures related to the present disclosure are illustrated in the accompanying drawings.
In the related art, the quality of the appearance of the meal box is generally detected manually or semi-automatically based on optical detection. The manual detection manner mainly relies on quality inspection personnel to observe the appearance photo of the meal boxes through their naked eyes, and give the judgment result by experience. The semi-automatic detection manner mainly relies on a quality inspection system to screen out defect-free meal boxes, and then relies on the quality inspection personnel to detect the appearance photo of the suspected meal box having the defects.
However, the above detection manners are easily affected by subjective factors of the quality inspection personnel, the criteria for defective judgment of the meal box is not unify, and it is easy to damage the eyes of the quality inspection personnel. Moreover, the detection accuracy and detection efficiency are low, and it cannot cover all the detection criteria of the box manufacturer, the expansibility is low.
At block S110, a detection request including an image of the meal box sent by a user terminal is received. The image of the meal box is obtained by an image acquirer of the user terminal.
In an embodiment of the present disclosure, the user terminal may be configured to control the production line of the meal box and the image acquisition of the meal box. The user terminal may be provided with an image acquirer, and the image acquirer may be a device capable of acquiring images, such as a camera. A high-precision image acquisition camera may be used for high-precision image acquisition, and by adjusting shooting parameters such as the shooting angle, auxiliary light, filter, scope and focal length, the image of the production line of the meal box can be acquired, such that the image of the meal box can be acquired. The material of the meal box to be detected is not limited, and any meal box may be applied to the embodiment, such as a plastic meal box, a plastic foam meal boxes, a metal meal box, or a glass meal box.
In the embodiment, the user terminal may generate the detection request according to the image of the meal box acquired by the image acquirer, and transmit the detection request to a server, such that the server receives the detection request, and performs defect recognition based on the image of the meal box. The detection request may include the image of the meal box, and the image of the meal box may include one image of the meal box, or may be multiple multi-view images of the meal box.
At block S120, defect recognition is performed based on the image of the meal box and a defect detection model in response to the detection request.
In an embodiment of the present disclosure, a defect detection model may be deployed in the server, and the defect detection model may be configured for defect recognition of the image of the meal box. The same defect detection model may be deployed in different servers, or defect detection models with different detection functions may be deployed in different servers. The defect detection model may be trained by a training engine based on historically labeled sample meal box images and business scenario requirements. For example, the defect type such as scratch, missing, and discoloration of the meal box may be pre-divided, and based on the defect locations and the defect types in the sample meal box images, the neural network model may be trained by using the sample meal box images, so as to obtain the defect detection model. The server may respond to the detection request, and perform defect recognition on the image of the meal box by using the defect detection model mounted thereon, so as to obtain the defect detection result of the image of the meal box. When it is detected that the meal box has a defect, the defect detection result may include parameters such as the defect type and the coordinates of the defect location.
In the embodiment, due to the influence of the imaging device, the imaging technology, and the imaging environment, the data characteristics of the image of the meal box may vary. Thus, before the target server recognizes the image of the meal box, the average value and the standard deviation of values of respective pixels in the image of the meal box may be determined, and normalization process may be performed on the values of respective pixels in the image of the meal box, such that the pixel data of the image of the meal box to be detected can be unified, subsequent standardized defect detection can be facilitated, and detection error can be reduced.
Correspondingly, after defect recognition is performed based on the image of the meal box and the defect detection model in response to the detection request, the server may perform a response behavior on the meal box based on the defect detection result of the image of the meal box and the business scenario requirement.
For example, when it is detected based on the image of the meal box that the meal box has a defect, a defect alarm instruction may be generated according to the recognized defect type and/or the defect location, and the defect alarm instruction may be transmitted to the user terminal to instruct the user terminal to alarm according to the defect alarm instruction, so as to inform the staff that the meal box having the defect is detected, and the defect type and the defect location. Alternatively, a meal box pick-out instruction may be generated according to the recognized defect type, and transmitted to the user terminal, to instruct a robot arm of the user terminal to pick out the meal box, so as to screen out the meal box having the defect. The plastic meal box may also be picked out according to the defect type, such that the staff can handle different types of meal box having the defect. For example, the meal box having the scratch may be remediated and reused.
Data such as the image of the meal box, the defect detection result and the response behavior may be stored in a database, and used to review the accuracy of defect detection and positioning, so as to update the defect detection model. Illustratively, correction information of a result of the defect recognition of the image of the meal box fed back by the staff or the detecting device may be obtained, new defect detection samples may be generated according to the correction information, and the defect detection model can be updated according to the new defect detection samples.
With the technical solution of embodiments of the present disclosure, the detection request including the image of the meal box sent by the user terminal is received, and defect recognition is performed based on the image of the meal box and the defect detection model in response to the detection request. The image of the meal box may be obtained by the image acquirer, the image acquirer may acquire the image of the meal box on the production line in real time, and the detection request may be generated based on the image of the meal box, and transmitted to the server. By detecting the image of the meal box obtained in real time, the defect detection of the meal box on the production line can be realized visually and automatically, and the manual detection of the quality of the meal box can be avoided, such that the efficiency and accuracy of defect detection of the meal box can be improved, and automaticity and expandability of the quality detection of the meal box can be improved.
On the basis of embodiment 1, the present disclose further provide a method for detecting defect of a meal box according to an alternative embodiment. In the embodiment, defect recognition is performed based on the image of the meal box and a defect detection model.
At block S210, a detection request including an image of the meal box sent by a user terminal is received.
In the embodiment, the user terminal may generate the detection request according to the image of the meal box acquired by the image acquirer, and transmit the detection request to a server, such that the server receives the detection request, and performs defect recognition on the image of the meal box. The detection request may include the image of the meal box, and the image of the meal box may include one image of the meal box, or may be multiple multi-view images of the meal box.
At block S220, an average value and a standard deviation of values of respective pixels in the image of the meal box is determined, and normalization process is performed on the values of the respective pixels in the image of the meal box according to the average value and the standard deviation.
In the embodiment, due to the influence of the imaging device, the imaging technology, and the imaging environment, the data characteristics of the image of the meal box may vary. Thus, before the target server recognizes the image of the meal box, the average value and the standard deviation of values of respective pixels in the image of the meal box may be determined, and normalization process may be performed on the values of respective pixels in the image of the meal box, such that the pixel data of the image of the meal box to be detected can be unified, subsequent standardized defect detection can be facilitated, and detection error can be reduced
At block S230, defect recognition is performed based on the image of the meal box and a defect detection model in response to the detection request.
In an embodiment of the present disclosure, a defect detection model may be deployed in the server, and the defect detection model may be configured for defect recognition of the image of the meal box. The defect detection model may be trained by a training engine by using initial meal box images or feature maps as input and based on historically labeled sample meal box images and business scenario requirements, to determine whether the meal box has the defect. When it is detected that the meal box has the defect, the defect type and the coordinates of the defect location may be output.
The training engine may train the defect detection model based on a deep convolution neural network, such as a mask region-based convolutional neural network (R-CNN) instance segmentation algorithm based on faster R-CNN. The deep convolutional neural network may include a convolutional layer, a pooling layer and a fully connected layer. The convolutional layer may be configured to perform convolution on the sample meal box images or the feature map by using convolutional kernels with different functions, extract data features, and output the data features to the feature map. The pooling layer may be configured to perform dimension reduction on the feature map, to retain main features in the feature map. With this deep neural network model, high robustness to deformation, blur and illumination changes of the image of the meal box on the production line can be achieved, and generalization of the classification task can be improved. The fully connected layer may be configured to map the extracted features to a defect location classification network. For different data characteristics of the image of the meal box and production scenes of the meal box, the corresponding deep convolutional neural model of different depths, different numbers of neurons, and different convolutional pooling modes can be designed, to train the defect detection model.
On the basis of the faster R-CNN algorithm, the mask R-CNN algorithm has a network branch for instance segmentation, which can restore the size of the feature map to the size of an initial image and predict the instance of each pixel based on a binary interpolation algorithm. For the prediction result of each pixel, a cross entropy operation may be performed with the real value to obtain a loss, and then training may be performing by combining the loss with the loss of the faster R-CNN, to optimize network model parameters.
The faster R-CNN algorithm may obtain the feature map based on the convolution of the classification model, and then determine whether a preset area of the initial sample meal box image includes a preset meal box by using a region proposal network (RPN). When the preset area of the sample meal box image includes the preset meal box, feature extraction may be performed using a convolutional network to predict the object category and the bounding box, when the preset area of the sample meal box image does not include the preset meal box, classification is not performed. The training is performed based on the losses of three network branches, the model parameters are further be optimized. When the difference between the output value and the true value of the model is less than a predetermined threshold, the training is stopped. The model that is running online can be gradually replaced by the well-trained model in a small flow online manner, such that the model can be generalized with dynamic expansion of the business.
In the embodiment, the same defect detection model may be deployed in different servers, and defect detection models with different detection functions may be deployed in different servers. The server may respond to the detection request, and perform defect recognition based on the image of the meal box and the defect detection model mounted thereon and by using the image of the meal box as the input of the defect detection model, so as to obtain the defect detection result of the image of the meal box. When it is detected based on the image of the meal box that the meal box has the defect, the output result may include parameters such as the defect type and the coordinates of the defect location. Then, the controller may perform a response behavior on the meal box based on the defect detection result of the image of the meal box and the business scenario requirement.
In at least one embodiment, when it is detected that the meal box has the defect, a defect alarm instruction may be generated according to the recognized defect type and/or the defect location, and the defect alarm instruction may be transmitted to the user terminal.

The plastic meal box may also be picked out according to the defect type, such that the staff can handle different types of meal box having the defect. For example, the meal box having the scratch may be remediated and reused.
