It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0054] In an exemplary embodiment, Figure 2 As shown, a method for identifying abnormal state of a protection plate is provided, and the method is applied to Figure 1 The detection end 100 in FIG. 1 is taken as an example to illustrate, including the following steps 201 to 203. Among them:

[0055] Step 201, obtaining an image of a protective pressure plate of a device under test.

[0056] The protective pressure plate image displays at least one protective pressure plate in the device to be tested.

[0057] Specifically, a user or a pre-installed camera shoots the protective pressure plate of the device to be tested to obtain a protective pressure plate image; the user end obtains the protective pressure plate image and sends the protective pressure plate image to the detection end; the detection end obtains the protective pressure plate image of the device to be tested.

[0058] Step 202, identifying the current pressure plate state of each protection pressure plate in the protection pressure plate image.

[0059] Specifically, based on the target detection algorithm, the protection pressure plate image is subjected to protection pressure plate detection to obtain at least one protection pressure plate; and the current pressure plate state of each protection pressure plate is determined.

[0060] Step 203, determining whether the protective pressure plate is abnormal according to the current pressure plate state of the protective pressure plate and the corresponding standard pressure plate state.

[0061] Specifically, for each protective pressure plate, a standard pressure plate state of the protective pressure plate is obtained; it is determined whether the current pressure plate state of the protective pressure plate is consistent with the corresponding standard pressure plate state; if not, it is determined that the protective pressure plate is abnormal.

[0062] In one embodiment, whether the protective pressure plate is abnormal is determined based on the current pressure plate state and the corresponding standard pressure plate state of the protective pressure plate, including: obtaining the device code of the device to be tested; using the preset pressure plate state corresponding to the device code as the standard pressure plate state of the protective pressure plate; when the current pressure plate state of the protective pressure plate is inconsistent with the corresponding standard pressure plate state, determining that the state detection result of the protective pressure plate is an abnormal result.

[0063] Specifically, obtain the device image code (such as a QR code) of the device to be tested uploaded by the user end; parse the device image code to obtain the device code of the device to be tested; index according to the device code to obtain a preset pressure plate state corresponding to the device code; use the preset pressure plate state corresponding to the device code as the standard pressure plate state of the protective pressure plate; when the current pressure plate state of the protective pressure plate is inconsistent with the corresponding standard pressure plate state, determine that the state detection result of the protective pressure plate is an abnormal result; otherwise, determine that the state detection result of the protective pressure plate is a normal result.

[0064] The above-mentioned method for identifying abnormal protection platen status obtains a protection platen image of the device to be tested; the protection platen image displays at least one protection platen in the device to be tested; the current platen status of each protection platen in the protection platen image is identified; and according to the current platen status of the protection platen and the corresponding standard platen status, whether the protection platen is abnormal is determined. This embodiment can more accurately and quickly determine the platen status of the protection platen, and by matching the detected platen status with the prior information in the database, automatic verification of the platen status is achieved. This process has a high degree of automation and reduces human errors.

[0065] In one embodiment, identifying the current pressure plate state of the protective pressure plate corresponding to the device under test in the protective pressure plate image includes: extracting features of the protective pressure plate image to obtain a pressure plate feature image; identifying each protective pressure plate in the pressure plate feature image to obtain a pressure plate identification result of each protective pressure plate; and determining the current pressure plate state of the corresponding protective pressure plate based on the pressure plate identification result of the protective pressure plate.

[0066] Specifically, the protective pressure plate image is preprocessed to obtain a preprocessed protective pressure plate image; features are extracted from the preprocessed protective pressure plate image to obtain a pressure plate feature image; each protective pressure plate in the pressure plate feature image is identified to obtain a pressure plate recognition result for each protective pressure plate; and the current pressure plate state of the corresponding protective pressure plate is determined based on the pressure plate recognition result of the protective pressure plate.

[0067] For example, Figure 3 The schematic diagram of the protection pressure plate state is shown in the figure, the left picture is the protection pressure plate image, and the right picture is the protection pressure plate image after preprocessing.

[0068] In one embodiment, each protective pressure plate in the pressure plate feature image is identified to obtain at least one protective pressure plate identification result, including: identifying at least one pressure plate initial identification result of each protective pressure plate from the pressure plate feature image; the pressure plate initial identification result includes a pressure plate initial identification frame and a confidence level corresponding to the pressure plate initial identification frame; and selecting the pressure plate identification result of each protective pressure plate based on the identification frame area and confidence level of each pressure plate initial identification frame corresponding to each protective pressure plate.

[0069] Specifically, based on the target detection algorithm, at least one initial pressure plate recognition result of each protective pressure plate is identified from the pressure plate feature image; and the pressure plate recognition result of each protective pressure plate is selected according to the recognition frame area and confidence of each pressure plate initial recognition frame corresponding to each protective pressure plate.

[0070] It should be noted that the target detection algorithm in this embodiment can be a target detection algorithm based on hybrid dilated convolution optimization. The dilated spatial pyramid pooling (ASPP) module is introduced to replace the spatial pyramid pooling (SPP) module in the YOLO V5 target detection network. The HDC network structure consists of three dilated convolutions with three convolution kernels of 3*3 and expansion rates of 1, 2, and 5 connected in series.

[0071] In one embodiment, a pressure plate recognition result of each protective pressure plate is selected based on the recognition frame area and confidence of each pressure plate initial recognition frame corresponding to each protective pressure plate, including: constructing a pressure plate initial recognition result set including each pressure plate initial recognition result; for each iteration process, selecting the pressure plate initial recognition result with the largest confidence from the pressure plate initial recognition result set as the pressure plate recognition result; determining the intersection-and-union ratio between the recognition frame area of ​​the protective pressure plate recognition result corresponding to the protective pressure plate recognition frame and the recognition frame areas of other pressure plate initial recognition frames; deleting the pressure plate initial recognition results with an intersection-and-union ratio greater than a preset intersection-and-union ratio threshold from the pressure plate initial recognition result set to update the pressure plate initial recognition result set until the pressure plate initial recognition result set is empty.

[0072] Specifically, a pressure plate initial recognition result set including the initial recognition results of each pressure plate is constructed, and for each iteration process, the pressure plate initial recognition result with the highest confidence is selected from the pressure plate initial recognition result set; the pressure plate initial recognition result with the highest confidence is used as the pressure plate recognition result; the intersection-and-union ratio between the recognition frame area of ​​the protective pressure plate recognition frame corresponding to the protection pressure plate recognition result and the recognition frame areas of other pressure plate initial recognition frames is determined; the pressure plate initial recognition results with an intersection-and-union ratio greater than a preset intersection-and-union ratio threshold are deleted from the pressure plate initial recognition result set to update the pressure plate initial recognition result set until the pressure plate initial recognition result set is empty.

[0073] In one embodiment, the intersection-and-union ratio between the recognition frame area of ​​the protective pressure plate recognition frame corresponding to the protection pressure plate recognition result and the recognition frame areas of other pressure plate initial recognition frames is determined, including: for each pressure plate initial recognition result other than the protection pressure plate recognition result in the pressure plate initial recognition result set, determining the intersection area between the pressure plate initial recognition frame and the protection pressure plate recognition frame; selecting the smaller recognition frame area between the recognition frame area of ​​the pressure plate initial recognition frame and the recognition frame area of ​​the protection pressure plate recognition frame as a reference area; and taking the ratio of the intersection area to the reference area as the intersection-and-union ratio.

[0074] Specifically, determine the intersection area between the initial platen identification frame and the protection platen identification frame; select the smaller identification frame area between the identification frame area of ​​the initial platen identification frame and the identification frame area of ​​the protection platen identification frame as the reference area; and use the ratio of the intersection area to the reference area as the intersection-union ratio using the following formula (1-1).

[0075] (1-1)

[0076] Among them, inter is the intersection area and min(A,B) is the reference area.

[0077] The above-mentioned protection plate state abnormality recognition method, hybrid hole convolution (HDC) network structure: by introducing a hybrid hole convolution layer, the network's receptive field is expanded and the network's feature extraction capability for small targets is enhanced, which is an innovation in the field of target detection, especially in small target detection. The newly added feature fusion path combines shallow detail features with deep abstract features, making up for the shortcomings of traditional target detection algorithms in small target detection and improving detection accuracy. Centralized processing of all category prediction boxes: The prediction boxes of different categories are processed centrally instead of separately. This improvement uses the screening mechanism of the NMS algorithm to effectively solve the problem of overlapping detection boxes for single-label non-overlapping objects. Redefine the calculation method of intersection over union (IoU): By adjusting the calculation method of IoU, the algorithm is more sensitive to the overlap of bounding boxes, thereby improving the accuracy of detection.

[0078] It should be understood that, although the various steps in the flowcharts involved in the above-mentioned embodiments are displayed in sequence according to the indication of the arrows, these steps are not necessarily executed in sequence according to the order indicated by the arrows. Unless there is a clear explanation in this article, the execution of these steps does not have a strict order restriction, and these steps can be executed in other orders.
