At present, the overall intelligent automation of the 3C industry (3C industry refers to the information appliance industry that integrates the application of computer, communication, and consumer electronics) is low. It can be seen from the investigation and analysis on the industry of display screens, such as mobile phone screens, the detection methods for mobile phone screen used by most of manufacturers can be divided into two types, namely: manual detection method and machine-assisted manual detection method.
The manual detection method refers to: an industry expert visually observe images captured from production environment and give judgements. This method is affected greatly by subjective factors of humans, has low detection efficiency, and does great harm to human eyes. In addition, since production workshop of display screen is generally a dust-free environment, staffs need to prepare for cleaning before entering, and wearing dust-free clothes, which may also adversely affect the health and safety of the staffs.
The machine-assisted manual detection method can also be called a detection method based on a liquid crystal module detection device, and the specific principle is: firstly, a quality detection system with certain judgment ability filters out images without defects, and then an industry expert detect and judge images with suspected defects. In the machine-assisted manual detection method, the quality detection system is mostly developed from the expert system and the characteristic engineering system, it means that the expert experience is solidified in the quality detection system, so that it has certain automation ability. Therefore, the machine-assisted manual detection method has low accuracy and poor system performance, and cannot cover all detecting standards of the manufacturer. Moreover, this method is also inefficient and easy to miss and misjudge defects, and the image data after detection is difficult to be used for secondary exploitation. In addition, in the aforementioned quality detection system, the characteristics and judgment rules are solidified into the machine according to the experience of the industry expert, and it is difficult to iterate with the development of the business, resulting in that the detection accuracy of the quality detection system becomes lower and lower with the development of the production process, and may even be reduced to a state of being completely unusable. In addition, the characteristics of the quality detection system are pre-solidified in hardware by third-party suppliers, and when upgrading, the production line needs to be substantially transformed, and the cost is very high, and it has obvious deficiencies in terms of safety, standardization and scalability, which is not conducive to the optimization and upgrading of the display screen production line, and the business scalability is low.
In summary, both the manual detection method and the machine-assisted manual detection method have the following disadvantages: not only inefficient, but also prone to misjudgment, and the industrial data generated by the two methods is not easy to store, manage, and re-excavate.
The embodiments of the present disclosure develop an automatic, high-precision, adaptive correction and upgrade display screen peripheral circuit detection method based on the latest development of artificial intelligence technology in computer vision, using an image of the display screen peripheral circuit captured by an image capturing device in real time on a production line of the display screen peripheral circuit, and detecting and judging surface quality of the display screen peripheral circuit in real time, if it is detected that there is a defect in a current image of the display screen peripheral circuit captured by the image capturing device, a marquee position in a picture of each defect and type of the defect are determined, and the embodiments of the present disclosure do not distinguish defective individuals from the same type of defects.
In an embodiment, the defects described in the embodiments of the present disclosure may include, but are not limited to, different types of defects including point defects, foreign matter defects, and scratch defects. No one is introduced here.
It should be understood that in the present disclosure, an object detection FAST RCNN algorithm is built on a previous deep convolutional neural network for effective classification and target detection. Object detection by FAST RCNN can locate a bounding box of an object. For example, in an image with a defect, not only the boundary box of the defect can be located (usually indicated by a marquee), but also the object inside the bounding box can be recognized as a certain type of defect. The marquee position of the defect in the present disclosure refers to a boundary box position where a defect is located. For example, if a scratch defect is framed by a red frame in an image to be detected, it indicates that the framed area is the position of the scratch defect, and the red frame corresponds to the scratch defect. Other types of defects may be indicated by other different colors.
Technical solutions of the present disclosure are described in detail below through specific embodiments. Following specific embodiments may be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments.
Following is a brief description of an application scene to which the embodiments of the present disclosure are applied. Referring to
The image capturing device 11 captures an image of the display screen peripheral circuit on a display circuit peripheral circuit production line, the console 12 receives the image of the display screen peripheral circuit acquired by the image capturing device 11, and sends the image of the display screen peripheral circuit to the detection model server 130 in the server group 13, the detection model server 130 inputs the received image of the display screen peripheral circuit into a defect detection model that runs on the detection model server 130 to obtain a defect detection result, the controller 14 receives the defect detection result of the detection model server 130, and gives a service response in combination with production stage information, and the controller 14 can also store the defect detection result in the database 15 as a log. In addition, the image of the display screen peripheral circuit captured by the image capturing device 11 can also be directly stored in the database 15 as a raw data for training the defect detection model. The trainer 16 extracts a historical image of a defective display screen peripheral circuit in the database and obtains the defect detection model based on the FAST RCNN algorithm training.
In an embodiment, the database 15 may include a production database 151 and a training database 152, the production database 151 can receive and save the defect detection result sent by the controller 14 and the image of the display screen peripheral circuit captured by the image capturing device 11, the training database 152 can store the historical image of the defective display screen peripheral circuit extracted from the production database 151 and a corresponding original image of the display screen peripheral circuit, so that the trainer 16 can obtain a defect detection model with high detection accuracy by training.
In an embodiment, the trainer 16 in the embodiment of the present disclosure may be a training engine implemented by hardware and/or software functions, as a training tool for the defect detection model. The system for detecting the display screen peripheral circuit of the embodiments of the present disclosure may further include other physical modules such as a processor and a memory, and the embodiment is not limited thereto.
S101, receiving a quality detection request sent by a console deployed on a production line of the display screen peripheral circuit, where the quality detection request includes an image of the display screen peripheral circuit captured by an image capturing device on the production line of the display screen peripheral circuit.
In the embodiment of the present disclosure, the production line of the display screen peripheral circuit can be deployed with multiple different devices, such as an image capturing device, a console, a server group, a controller, a database. The image capturing device can be a high precision image capturing camera, and in a production process of the display screen peripheral circuit, it is possible to capture a plurality of images of the display screen peripheral circuit corresponding to the display screen peripheral circuits which are in the production process, by adjusting the angle, light, filter, zoom lens, focus, etc. of the image capturing device.
After the image of the display screen peripheral circuit is captured by the image capturing device on the production line of the display screen peripheral circuit, the console deployed on the production line of the display screen peripheral circuit can send a quality detection request to the server group on which the defect detection model is deployed on the production line of the display screen peripheral circuit, the quality detection request includes the image of the display screen peripheral circuit captured by the image capturing device, so that a server that receives the quality detection request in the server group processes the received image of the display screen peripheral circuit.
S102, enlarging or reducing the image of the display screen peripheral circuit to obtain an image to be detected, where a size of the image to be detected is consistent with an input size requirement of a defect detection model.
S103, inputting the image to be detected into the defect detection model to obtain a defect detection result.
The defect detection model is obtained by using a historical image of a defective display screen peripheral circuit to perform object detection FAST RCNN algorithm training. The defect detection model obtained by the object detection FAST RCNN training has a size requirement for the input image. Once the size of the input image is inconsistent with the input size requirement of the model, the input image cannot be processed by the defect detection model. When the display screen peripheral circuit is detected, the line orientation and winding shape indicated by the global image can better represent its possible defects, therefore, in the embodiment, an image of the display screen peripheral circuit is first scaled so that the size of the image to be detected is consistent with the input size requirement of the defect detection model before inputting into the defect detection model.
Enlarging or reducing the image of the display screen peripheral circuit can be understood as enlarging or reducing with the pixel unchanged, and can also be understood as enlarging or reducing with pixel reduction. If the pixel is too high, processing capability of the defect detection model may be exceeded. Therefore, if the pixel of the image of the display screen peripheral circuit is too high, it is also possible to perform pixel-down processing on the image of the display screen peripheral circuit first, which is not limited herein.
In an embodiment, a server that receives the quality detection request acquires the image of the display screen peripheral circuit in the quality detection request, and performs preprocessing of enlargement or reduction to obtain an image to be detected whose size is consistent with the input size requirement of the defect detection model. Then, the image to be detected is input into the defect detection model running on the server, and defect detection is performed by the defect detection model, thereby the defect detection result is obtained.
In an implementation, image of the display screen peripheral circuit can also be preprocessed before the enlargement or reduction of the image of the display screen peripheral circuit, where the image preprocessing includes one or more of following processes: trimming, cutting, and rotating. It can be understood that the image capturing device deployed on the production line of the display screen peripheral circuit is generally a high-precision camera, therefore, the image of the display screen peripheral circuit captured by the image capturing device may have a large size, or a high pixel, or an inappropriate position. Therefore, after the image of the display screen peripheral circuit included in the quality detection request sent by the console is received, the image of the display screen peripheral circuit needs to be preprocessed according to actual conditions. For example, if the edge area of the image of the display screen peripheral circuit is large, the image of the display screen peripheral circuit may be trimmed to retain the useful part of the image of the display screen peripheral circuit.
It is worth noting that the defect detection model running on the server is obtained by performing the object defect detection FAST RCNN algorithm training on the historical image of the defective display screen peripheral circuit. Specifically, the FAST RCNN algorithm is used for object detection in the embodiment. Object detection refers to letting the computer detect according to what object is in the image, that is, whether the image to be detected contains defects and the type of defects when the defect is included are identified. In the embodiment of the present disclosure, the defect detection model uses FAST RCNN structure. Specifically, the image of the display screen peripheral circuit of the production line of the display screen peripheral circuit is used as an input of the defect detection model, and the FAST RCNN structure of the defect detection model is used to identify characteristics of the image of the display screen peripheral circuit, that is, to obtain which images in the image to be detected are normal images without defects, and which images are defective images with defects, and for the defective image, it also can identify the type of defect included in the image, and determine the marquee position where the defect is located by using the bounding box.
As an example, before the inputting the image of the display screen peripheral circuit into the defect detection model to obtain a defect detection result, a model training process may also be included. Specifically, it can be performing the FAST RCNN algorithm training on the defect detection model with the actual type of the historical image of the defective display screen peripheral circuit, so that a loss value between a prediction type which is outputted by the defect detection model for the historical image of the defective display screen peripheral circuit and the actual type is lower than a preset loss threshold.
The loss value can be understood as a total loss value, the defect detection model is a result that performing combined training on a candidate region loss value, a region type loss value, and a region boundary loss value of the historical defect display image, so that the total loss value of the candidate region loss value, the region type loss value, and the region boundary loss value satisfy a preset loss threshold. The candidate region loss value refers to a loss value between a selected defect region and an actual defect region in the historical image of the defective display screen, the area type loss value refers to a loss value between a predicted defect type and an actual defect type in the selected defect area, the region boundary loss value refers to a loss value between a predicted defect boundary and an actual defect boundary in the selected defect region.
The embodiments of the present disclosure can utilize the FAST RCNN model, which have high robustness to deformation, blur, and illumination changes of the image of the display screen peripheral circuit captured by the image capturing device on the production line of the display screen peripheral circuit, and has higher generalization for classification tasks.
It is worth noting that, in the embodiment of the present disclosure, for different production scenes and characteristics of the image of the display screen peripheral circuit, the FAST RCNN model required to train the defect detection model may be organized differently, which may be determined according to actual conditions, and it is not limited in this embodiment.
S104, determining, according to the defect detection result, quality of a display screen peripheral circuit corresponding to the image of the display screen peripheral circuit.
In the embodiment of the disclosure, after the defect detection result is obtained according to the defect detection model, quality of the display screen peripheral circuit corresponding to the image of the display screen peripheral circuit may be determined according to the defect detection result.
In an embodiment of the disclosure, the defect detection result may include: a type of a defect, and/or a marquee position of each defect. For example, when there is a defect in the image of the display screen peripheral circuit, the defect detection result that can be obtained by the defect detection model may include types of the defects (how many types of defects exist on the display screen peripheral circuit), and marquee positions of the defects (the position of each defect is indicated by a marquee). The way in which the defect detection result is presented can be understood as, the defect detection model outputs a characteristic pattern with a marquee, and the marquee frames and displays a defect contained in the image to be detected, and the marquee corresponds to a result of a type of the defect. The position of the defect in the image of the display screen peripheral circuit can be determined by the position of the marquee.
Correspondingly, S104 (determining, according to the defect detection result, quality of the display screen peripheral circuit corresponding to the image of the display screen peripheral circuit) may be replaced by: determining, according to production stage information and the defect detection result, quality of the display screen peripheral circuit corresponding to the image of the display screen peripheral circuit.
Specifically, various production stage information such as manufacturer, production environment, and type of the display screen peripheral circuit may obtain different defect detection results in the display screen peripheral circuit detection process. For different types of display screen peripheral circuits, the production stages they experience are different, therefore, when analyzing the defect detection result obtained above, it is necessary to combine the production stage information of each display screen peripheral circuit to determine the quality of the display screen peripheral circuit.
It is worth noting that, the defect detection model of the embodiment of the present disclosure can detect the types of the defects in the image of the display screen peripheral circuit, and the marquee position of each type of defect, without identifying the specific defect contour and the defect individual, thereby reducing the operation load.
The method for detecting the display screen peripheral circuit provided by the embodiment of the present disclosure, by receiving a quality detection request sent by a console deployed on a production line of the display screen peripheral circuit, the quality detection request includes an image of the display screen peripheral circuit captured by an image capturing device on a production line of the display screen peripheral circuit, inputting the image to be detected into the defect detection model to obtain a defect detection result, and determining, according to the defect detection result, quality of the display screen peripheral circuit corresponding to the image of the display screen peripheral circuit. Since the defect detection model is obtained by performing the FAST RCNN algorithm training on the historical image of a defective display screen peripheral circuit, the defect detection result obtained by the defect detection model has high classification accuracy, and strong intelligence capability, the system performance is improved, and the business scalability is high.
S301, determining a detection model server carrying a processing resource according to a load balancing policy.
In the embodiment of the disclosure, a server group is deployed on the production line of the display screen peripheral circuit, the number of servers in the server group can be multiple, each of which runs a defect detection model. In an embodiment, the defect detection model running on each server is the same. Therefore, each server can receive the quality detection request sent by the console, so that the quality detection can be performed on an image of the display screen peripheral circuit by using the defect detection model carried by itself.
As an example, since the image capturing device deployed on the production line of the display screen peripheral circuit captures the image of the display screen peripheral circuit in real time, the console can also send a quality detection request to any server in the server group in real time.
In an embodiment, since the defect detection model running on each server in the server group is the same, in order to improve the detection efficiency of the defect detection model on the server, and ensure load balancing of the defect detection model, a server can be determined, according to a preset load balancing policy, from the server group as a detection model server carrying the processing resource, that is, load balancing and scheduling can be performed in real time according to the deployment situation of the defect detection model on the production line of the display screen peripheral circuit.
S302, inputting the image to be detected into the defect detection model running on the detection model server to obtain a defect detection result.
In the embodiment of the present disclosure, after determining the detection model server carrying the processing resource from the server group, the image of the display screen peripheral circuit may be input to the defect detection model running on the detection model server, defect of the image of the display screen peripheral circuit is detected by using the defect detection model, then the defect detection result is obtained. In an embodiment, the defect detection model is obtained training a preset type and an actual type of the historical image of a defective display screen peripheral circuit by the training module.
The method for detecting the display screen peripheral circuit provided by the embodiment of the present disclosure, by determining a detection model server carrying a processing resource according to a load balancing policy, and inputting the image to be detected into a defect detection model running on the detection model server to obtain a defect detection result, which can achieve load balancing on the server, improve detection efficiency of the image of the display screen peripheral circuit, and improve the performance of the system for detecting the display screen peripheral circuit.
In an implementation, after the S302 (inputting the image to be detected into a defect detection model running on the detection model server to obtain a defect detection result), can also include following steps:
if it is determined that the display screen peripheral circuit is a damaged circuit, performing one or more of following operations:
sending, through a controller, alarm information to a production manager;
storing, through the controller, the defect detection result in a production database as a log;
sending, through the controller, a production control instruction to the console to eliminate a defect;
inputting the image of the display screen peripheral circuit and the defect detection result into the defect detection model to optimize the defect detection model.
In embodiments of the present disclosure, the tester can pre-set a solution when determining the display screen peripheral circuit as a damaged screen according to production scenes and production stage information of the display screen peripheral circuit, for example, sending, through a controller, alarm information to a production manager, and/or storing, through the controller, the defect detection result in a production database as a log, and/or sending, through the controller, a production control instruction to the console to eliminate a defect, and/or, inputting the image of the display screen peripheral circuit and the defect detection result into the defect detection model to optimize the defect detection model, etc.
Specifically, as an example, when it is determined that the display screen peripheral circuit corresponding to the image of the display screen peripheral circuit is a damaged circuit according to the defect detection result, that is, there is a defect in the display screen peripheral circuit, an alarm message may be issued to enable the production manager to locate the type and position of the defect in time, and provide a solution.
As another example, when it is determined that there is a defect in the display screen peripheral circuit according to the defect detection result, the defect detection result may be stored into the production database as a log through the controller, that is, the type of the defect in the display screen peripheral circuit, and/or the marquee position of the defect is stored into the production database as a log, which can further be filtered into the training database, the training module (which may be a software program such as a training engine) may update the defect detection model according to the image of the display screen peripheral circuit having a defect.
As still another example, when it is determined that there is a defect in the display screen peripheral circuit according to the defect detection result, the controller may also send a production control instruction to the console to eliminate the defect. That is, the detection model server carrying the defect detection model can determine the cause of the defect through the controller, and then adjust the production process correspondingly, also that is, the detection model server sends a production control instruction to the console through the controller to eliminate defects occurring on the display screen peripheral circuit to reduce the probability of damaged circuit.
As still another example, when it is determined that there is a defect in the display screen peripheral circuit according to the defect detection result, the image of the display screen peripheral circuit and the defect detection result may be directly input into the defect detection model to optimize the defect detection model, that is, the image of the display screen peripheral circuit corresponding to the damaged circuit is directly used as a training set of the defect detection model to optimize the defect detection model, thereby improving the detection accuracy of the defect detection model.
It is worth noting that, the embodiment of the present disclosure is not limited to one or more operations performed by the detection model server when determined that the display screen peripheral circuit is a damaged circuit, which may be determined according to actual conditions, and details are not described herein again.
In an embodiment, for a variety of different devices such as the image capturing device, the console, the server group, the controller, the database, etc. deployed on the production line of the display screen peripheral circuit, the method for detecting the display screen peripheral circuit may also be performed by distributing the corresponding operation steps to the plurality of different devices. For example, the image capturing device captures an image of the display screen peripheral circuit, and the console sends the image of the display screen peripheral circuit captured by the image capturing device to the detection model server in the server group according to the load balancing policy, after performing pre-set preprocessing on the image of the display screen peripheral circuit by the defect detection model running on the detection model server, performing defect detection, and then giving the defect detection result. The detection model server can send the defect detection result to the controller, on one hand, the controller combines an actual business scene, and according to the service requirement, and a response corresponding to the actual business scene requirement is generated according to the defect detection result, such as alarming, storage log, and control production control instructions, etc., on the other hand, the controller may further store the defect detection result and a processing behavior of the response into the production database as a log, so that the training module updates the obtained defect detection model according to the image of the display screen peripheral circuit and the defect detection result in the training database, the training database stores data such as an image of the display screen peripheral circuit with defect and corresponding defect detection results filtered from the production database.
It is worth noting that, for each optimized defect detection model, the defect detection model running on the server can be gradually replaced by the small traffic on-line, so as to achieve a purpose of the defect detection model dynamically expanding with the business scene and the production stage information. In the embodiment of the present disclosure, after the method for detecting the display screen peripheral circuit is run for a period of time on the production line of the display screen peripheral circuit, the accuracy of the defect detection and defect location can be reviewed manually through the information in the production database, then the training database is updated, and the defect detection model is retrained to improve the defect detection accuracy.
