Detailed Description
The embodiment of the invention provides a method, a device, equipment and a storage medium for testing a display screen module, which are used for realizing intelligent analysis of parameters of the display screen module and improving the testing accuracy of the display screen module. The terms "first," "second," "third," "fourth" and the like in the description and in the claims and in the above drawings, if any, are used for distinguishing between similar objects and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used may be interchanged where appropriate such that the embodiments described herein may be implemented in other sequences than those illustrated or otherwise described herein. Furthermore, the terms "comprises," "comprising," or any other variation thereof, are intended to cover a non-exclusive inclusion, such that a process, method, system, article, or apparatus that comprises a list of steps or elements is not necessarily limited to those steps or elements expressly listed or inherent to such process, method, article, or apparatus.
For easy understanding, the following describes a specific flow of an embodiment of the present invention, referring to fig. 1, and an embodiment of a method for testing a display screen module in an embodiment of the present invention includes:
s101, performing test analysis on a target display screen module based on preset test time and test parameters to obtain original test data, and performing data standardization processing on the original test data to obtain standard test data;
it can be understood that the execution body of the present invention may be a testing device of a display screen module, and may also be a terminal or a server, which is not limited herein. The embodiment of the invention is described by taking a server as an execution main body as an example.
Specifically, the server determines the time and parameters of the test to ensure that the test can be accurately performed on the target display screen module, and further, the test instrument is used for testing the target display screen module, and each test result is recorded. For example, indexes such as brightness, contrast, resolution, response time and the like of a display screen can be tested, test results are recorded through an instrument, recorded values of each test index are arranged to obtain original test data, subsequent data processing and analysis are convenient, and it is noted that the test data are required to be subjected to standardized processing because the test instruments possibly have different differences in precision, range and the like, so that the test data are comparable, and the subsequent analysis is convenient. For example, the test data may be subjected to average calculation, numerical scaling, and the like to obtain standard test data.
For example, assume that the screen brightness and resolution of a certain handset need to be tested: presetting test time and parameters: the test can be continued for 30 minutes under indoor conditions, and the two indexes of brightness and resolution can be tested. And testing the mobile phone screen by using a measuring instrument, and recording the result of each test. For example, the brightness of the screen can be tested under different light conditions, corresponding values on the testing instrument are recorded, meanwhile, the resolution is tested, and the testing result is recorded. The records of each test are sorted to obtain original test data, for example, 10 brightness test results and 10 resolution test results. And carrying out average value calculation on the test data to obtain average brightness and average resolution, and simultaneously carrying out operations such as numerical scaling and the like to obtain standard test data.
S102, classifying and extracting display characteristic parameters of standard test data to obtain brightness display characteristic parameters and color display characteristic parameters, and generating a display characteristic association curve according to the brightness display characteristic parameters and the color display characteristic parameters;
specifically, the server classifies and extracts the brightness display characteristic parameters and the color display characteristic parameters from the original test data, classifies and marks the extracted parameters respectively for convenient subsequent processing, trains and learns the standard test data, establishes classification and extraction algorithms for the brightness and color display characteristic parameters, for example, extracts the brightness parameters by detecting the change of pixel intensity, obtains the color parameters by using color space conversion, establishes a corresponding data association relation model based on the brightness and color display characteristic parameters, and generates a display characteristic association curve by using the model. For this purpose, a logarithmic factor decomposition method, a polar moment method or a neural network method can be selected to establish a correlation model between the brightness and color display characteristic parameters, and the original test data is preprocessed, including noise filtering and outlier processing. And (3) carrying out standardization processing on the data to eliminate the difference between different data sources, and using the standardized data for classification and extraction.
S103, carrying out display anomaly analysis on the display characteristic association curve to obtain a brightness and color anomaly value pair, and generating a target anomaly vector according to the brightness and color anomaly value pair;
the server first performs anomaly detection on the display characteristic association curve to find atypical parts, marks positions and values of anomaly data points by using an anomaly detection method, analyzes anomalies based on the marked data, and may select a z-score anomaly detection method or an IQR anomaly detection method to find anomaly data, extract values in brightness and color value pairs of the marked anomaly data points, and store the brightness and color value pairs in a list of corresponding brightness anomaly value pairs and color anomaly value pairs. For example, for an image, its display characteristic association curve includes 50 points, 5 of which are marked as outliers. The 5 outliers can extract the values in the luminance and color value pairs to generate a corresponding outlier value pair list, average the luminance and color outlier value pairs to generate two target outliers, namely a luminance target outlier and a color target outlier, and combine the luminance and color target outliers into one vector, namely a target outlier vector, for example, for the 5 luminance outlier value pairs and the color outlier pairs, average the values respectively to obtain a luminance target outlier and a color target outlier, and then combine the two target outliers into one vector, namely a target outlier vector.
When this step is performed, for a display characteristic association curve, the z-score anomaly detection method is used to find anomaly points therein, label their positions and values, for these labeled anomaly data points, extract the values in their brightness and color value pairs to generate brightness anomaly value pairs and color anomaly value pair lists, respectively, for each list, add up all the values and divide by the corresponding list length to obtain brightness and color target anomaly values, and finally the server combines the brightness and color target anomaly values into a binary group as a target anomaly vector and returns.
S104, inputting the target abnormal vector into a preset display screen abnormal analysis model to perform display screen abnormal analysis, and obtaining a display screen abnormal analysis result;
specifically, in a preset model library, an abnormal analysis model conforming to the characteristics of the current display screen is selected.
Determining model input, output and parameters, inputting a target abnormal vector into the model, running the model, and generating a display screen abnormal analysis result, for example, a classifier, a neural network or a support vector machine and other models can be selected to realize abnormal analysis.
It should be noted that, in the embodiment of the present invention, an anomaly analysis model suitable for the current display screen is selected from a preset model library. In this step, the input, output and parameters of the model need to be determined, the target anomaly vector is input into the model, the model is executed, and the display anomaly analysis results generated by the processing model are analyzed to determine the type and intensity of the display anomaly, for example, if display anomaly sample data has been collected, these data can be used to train a support vector machine anomaly detection model. After training is completed, the model may be run with the target anomaly vector as input. Finally, according to the output of the model, the abnormal type and intensity of the display screen are evaluated.
In the step of the invention, an abnormality analysis model which is least influenced by the characteristics of the current display screen (object to be analyzed) is selected from the existing model library, basic information such as input, output and parameters of the model is confirmed, a target abnormality vector is used as input into the model, and the model is executed. And trimming and standardizing the non-zero output data (abnormal score), and judging the abnormal type and intensity of the display screen according to the result of model analysis and domain knowledge.
S105, extracting characteristic parameters of the reaction speed in the standard test data, and verifying analysis results of abnormal analysis results of the display screen according to the characteristic parameters of the reaction speed to obtain target verification results;
specifically, the server extracts reaction speed characteristic parameters such as reaction time and accuracy from standard test data, classifies and marks the extracted characteristic parameters for convenient subsequent processing, establishes a specific reaction speed model based on the reaction speed characteristic parameters, for example, can acquire the reaction time and accuracy of a user under different test conditions from the standard test data, classifies the reaction time and accuracy, establishes a proper model based on the characteristics, correlates the obtained characteristic parameters with a display screen abnormality analysis result, calculates a target verification score according to the established reaction speed model by using the characteristic parameters such as the reaction time and accuracy, determines whether the abnormal condition exists on the display screen according to the verification score, for example, can correlate the generated display screen abnormality analysis result with the generated reaction speed characteristic parameters, input the generated display screen abnormality analysis result with the generated reaction speed characteristic parameters into the specific reaction speed model, and calculates a target verification score by using the model. If the score exceeds a preset threshold, the display screen abnormality may be confirmed.
In the step of the invention, the server extracts reaction speed characteristic parameters such as reaction time and accuracy from standard test data, classifies and marks the reaction speed characteristic parameters, establishes a proper reaction speed model based on the reaction speed characteristic parameters, correlates the obtained display screen abnormal analysis result with the reaction speed characteristic parameters to form a verification data set, calculates a target verification score of each data point in the verification data set by using the reaction speed model, determines the verification result according to the score and a preset threshold value, and judges whether the display screen has abnormal conditions, for example, for a certain detection task, standard test data can be collected and the two characteristic parameters of the reaction time and the accuracy can be extracted from the standard test data. An appropriate model is then built based on these two parameters. It is assumed that abnormality analysis has been performed for a certain display screen and abnormality data is acquired. The anomaly data can be associated with the two characteristic parameters and constitute a validation data set. Then, a target verification score for verifying the data point is calculated using the speculative model. And finally, determining a verification result according to the score and a threshold value, and judging whether the display screen has abnormal conditions or not.
S106, generating a display screen abnormality processing strategy of the target display screen module according to the target verification result and the display screen abnormality analysis result.
Specifically, the reaction speed characteristic parameters and the display screen abnormality analysis result are integrated, the integrated data are subjected to data cleaning and preprocessing, such as removing low-quality data points or performing data smoothing processing, a machine learning algorithm such as regression or classification model is used for generating a correlation model of the target verification result and the display screen abnormality analysis result, for example, a multiple regression analysis method can be used for integrating the target verification result and the display screen abnormality analysis result, and then a model is trained for predicting the display screen abnormality condition.
By using the existing knowledge and prior experience, generating a display screen abnormality processing strategy according to the model prediction result, and generating an execution guide of a specific strategy according to different types and grades of the abnormality strategy, for example, if the display screen abnormality analysis result is a software error, the problem can be solved by using upgrading or debugging software. And if the hardware is in fault, performing troubleshooting according to a fault removal flow.
In the step of the invention, the server integrates the reaction speed characteristic parameters and the display screen abnormality analysis results, uses the integrated data to train a correlation model or expert system, uses the model or expert system to predict the relation between the target verification result and the display screen abnormality analysis results, determines the display screen abnormality processing strategy, generates a specific execution guide according to different types and grades of the strategy, operates specific conditions, such as processing abnormal data of a certain display screen, integrates the abnormal data with the reaction speed characteristic parameters, and uses a stepwise regression model to predict the relation between the target verification result and the abnormality analysis results. After the model result is obtained, the type and degree of the display screen abnormality can be judged, and a corresponding abnormality processing strategy is generated based on the prediction result. If the display screen abnormality degree is light, the processing can be performed based on a self-repairing strategy. If the display screen abnormality is serious, a more complex troubleshooting procedure is adopted to deal with the problem.
