Detailed Description
The technical scheme of the application will be described below with reference to the accompanying drawings.
Fig. 1 is a schematic diagram of an application scenario suitable for the present application, in which an industrial personal computer 600 is in communication connection with a screen 001 to be tested for sending a test image to the screen 001 to be tested, and the industrial personal computer 600 is in communication connection with a measuring instrument 002 for sending an optical parameter to be tested to the measuring instrument 002 and obtaining a parameter value of the optical parameter to be tested collected by the measuring instrument 002.
In some related art, in order to perform an omnidirectional test on the display performance of the screen 001 to be tested, a plurality of test items (for example, contrast, brightness uniformity, white balance error, etc.) need to be measured. In this regard, when measuring different test items, a tester needs to manually adjust the measuring instrument 002 to perform a test, collect the parameter values of the optical parameters of the screen 001 to be measured, manually record the parameter values of the optical parameters displayed by the measuring instrument 002, and analyze the display performance of the screen 001 to be measured.
It will be appreciated that the above-described test steps are manually performed, which is cumbersome to operate. Meanwhile, the accuracy of manual execution is not high, careless mistakes are easy to occur due to fatigue and other reasons, the parameter values of unnecessary optical parameters are collected by the control measuring instrument 002, errors occur when the parameter values of the optical parameters displayed by the measuring instrument 002 are counted, the display performance calculated according to the parameter values of the optical parameters is inaccurate, and the like, and the test efficiency is low.
In addition, when executing different test items, in order to reduce the human input, the screen 001 to be tested displays a random or uniform test picture, and cannot accurately obtain the parameter values of the optical parameters corresponding to each test item. The display performance of the screen to be tested is not accurately tested, and even if the screen 001 to be tested is detected to be tested according to the testing mode, the screen to be tested is qualified, the screen to be tested can be a defective product, and the user experience is affected.
In some related arts, there are also schemes for autonomous detection of a screen, but usually multiple test items are tested for a set of images, and the test accuracy is low.
In this regard, the present application proposes a screen testing method, which is applied to the industrial personal computer 600, and the screen testing method 100 provided by the present application will be described in detail with reference to fig. 2.
It should be noted that, in the present application, terms such as "first", "second", and the like are used to distinguish different individuals in the same type of object, for example, the first test item and the second test item represent two different test items, and there is no other limitation.
The method 100 may be performed by the industrial personal computer 600 shown in fig. 1. As shown in fig. 2, method 100 includes the following.
S110, detecting a test task, wherein the test task comprises at least one test item.
Optionally, before detecting the test task, the current test environment is detected, and the communication state between the devices is confirmed. For example, the industrial personal computer sends handshake information to each device (to-be-tested screen, measuring instrument and the like), and after receiving feedback of the handshake information, the industrial personal computer confirms that communication with each device is normal, namely, the testing environment is normal.
Optionally, before detecting the test task, the qualification criteria of each test item may be adjusted according to the requirements of the target user. For example, the natural environment of the north-south hemisphere is different, and the white balance parameters to be displayed are different. Therefore, before the screen to be tested is tested, the qualification standard of the white balance (such as inputting RGB values under the common color temperature) is adaptively adjusted, so that the display performance of the finally obtained screen to be tested better meets the requirements of target users.
Optionally, the at least one test item includes one or more of a gamma curve test, a contrast test, a brightness uniformity test, a color temperature test, a color gamut test, a white balance error test, a bare screen test.
In the embodiment, more executable test items can be provided, the display performance of the screen to be tested can be tested in each dimension, the display performance of the screen to be tested is mastered more comprehensively, and the accuracy of screen test is improved on the premise of ensuring the screen test efficiency.
The test items may be checked by a tester in a display interface of the industrial personal computer.
S120, according to at least one test item, obtaining a test image corresponding to each test item and optical parameters to be tested corresponding to each test item.
That is, different test items are preset with specific test images and corresponding optical parameters to be tested, and after a tester selects the test items, the industrial control computer can read the test images and the optical parameters to be tested corresponding to the test items, so that preparation for testing is made.
Optionally, when the test item is a gamma curve test, the corresponding test image is a group of gray level images arranged according to the gray level value, and the corresponding optical parameter to be tested is brightness. For confirming whether the brightness variation of the screen is uniform or not or whether the brightness variation of the screen accords with the use habit of the target user when the gray level variation in the screen to be tested is changed.
Optionally, when the test item is a contrast test, the corresponding test image is a pure black image (gray value is 0) and a pure white image (gray value is 255), and the corresponding optical parameter to be tested is brightness, so as to confirm the brightness limit of the screen to be tested. Specifically, a first brightness value of a center point of a pure white image can be obtained, a second brightness value of an edge of a pure black image can be obtained, and a contrast value calculated according to the first brightness value and the second brightness value can more represent the brightness limit of a screen to be tested.
Optionally, when the test item is a brightness uniformity test, the corresponding test image is a solid-color image, and the corresponding optical parameter to be tested is brightness, so as to determine whether the display brightness of the screen to be tested is uniform or whether the brightness of each area is within a reasonable range. Specifically, brightness values of different preset point positions in the image can be obtained, and brightness uniformity of the screen to be tested is calculated and confirmed.
Optionally, when the test item is a color temperature test, the corresponding test image is a pure white image (the gray value is 255), and the corresponding optical parameter to be tested is a color temperature, so as to determine whether the color temperature value is in a normal acceptable state range.
Optionally, when the test item is a color gamut test, the corresponding test image is a set of RGB images including red images with R values of 255, G values and B values of 0, green images with G values of 255, R values and B values of 0, and blue images with B values of 255, R values and G values of 0. The corresponding optical parameters to be measured are RGB values of each image or xy values of each image in XYZ color space, and are used for confirming the maximum color range which can be represented by the screen to be measured.
Optionally, when the test item is a white balance error test, the corresponding test image is a set of gray level images, and the corresponding optical parameter to be tested is chromaticity (uv value in YUV data format), so as to determine whether the error of the white balance of the screen to be tested is within the allowable range.
Optionally, when the test item is a bare screen test, the corresponding test image is null, that is, no test image is displayed, and the corresponding optical parameter to be tested is brightness or color temperature, so as to confirm the conventional performance of the screen hardware to be tested.
S130, sending test images corresponding to the test items to the screen to be tested, so that the screen to be tested displays the test images.
Optionally, after the test item is detected, a test item queue of the test item is generated, and the test items are sequentially executed according to the test item queue. For example, the test items are ordered by checking the order of the test items, or the test items are randomly ordered, to obtain a test item queue. When the test images corresponding to the test items are sent to the screen to be tested, the test images are sequentially sent according to the sequence of the test items in the test item queue. The mutual influence of test images among test items is avoided, and the error probability is reduced.
Illustratively, if the test item includes a bare screen test, the bare screen test is arranged at the head of the test item queue. Because the screen to be tested does not need to display any picture when the bare screen is tested, the influence of other test items executed in advance on the display picture of the bare screen test is avoided, and the inaccurate test result of the bare screen is caused.
Optionally, the pixel values of different pixel points in the test image are the same, and the test image corresponding to each test item is sent to the screen to be tested so that the test image is displayed on the screen to be tested, and the method comprises the steps of sending the pixel value of any pixel point in the test image corresponding to each test item to the screen to be tested so that the test image is displayed on the screen to be tested.
The pixel values may be RGB parameter values, for example.
After the screen to be tested receives the pixel value, a test image is generated according to the pixel value and a preset resolution or size parameter, and finally the test image is displayed.
In the embodiment, the pixel value of one pixel point can be sent to the screen to be tested, so that the screen to be tested displays the test image according to the pixel value and the preset resolution.
Meanwhile, the test image is directly generated according to the pixel value, so that the accuracy of the test image can be ensured. If the complete image data is sent, the problems of packet loss and the like occur in the transmission process due to the large data volume of the test image (including the position information of each pixel point, the pixel value of each pixel point and the like), so that the display of the test image displayed on the screen to be tested is inaccurate due to the loss of details and the like, and the test result is affected.
And S140, transmitting the optical parameters to be measured corresponding to each test item to the measuring instrument so that the measuring instrument can acquire the parameter values of the optical parameters to be measured.
Alternatively, the measuring instrument is a color analyzer CA410.
It can be understood that when the measuring instrument collects the parameter value of the optical parameter to be measured corresponding to the test item in the screen to be measured, the screen to be measured displays the test image corresponding to the test item.
Optionally, the industrial personal computer sends the optical parameters to be tested to the measuring instrument, for example, the test items correspond to brightness, color temperature and the like to be tested.
Optionally, if the test images corresponding to the test items include at least two identical test images, the at least two identical test images correspond to the target test item in the at least one test item, and the sending of the optical parameters to be tested corresponding to the test items to the measuring instrument includes sending the optical parameters to be tested corresponding to the target test item to the measuring instrument at the same time, so that the measuring instrument can collect the parameter values of the optical parameters to be tested corresponding to the target test item at the same time.
The target test items are at least two test items corresponding to the same test image.
In this embodiment, when at least two test images in the test images corresponding to the plurality of test items are the same, at least two corresponding test items (target test items) may be tested simultaneously when the test images are displayed, that is, the measuring instrument is enabled to collect parameter values of the optical parameters to be tested corresponding to the at least two test items (target test items) simultaneously. Compared with the mode that each test item is independently executed, the scheme can reduce the test duration of the screen to be tested to a certain extent, and improves the test efficiency.
For example, when the test items include a contrast test and a color temperature test, the test images corresponding to the contrast test are a solid black image and a solid white image, and the test images corresponding to the color temperature test are solid white images, that is, solid white images exist in the test images. Therefore, the brightness to be measured in contrast test and the color temperature to be measured in color temperature test are sent to the measuring instrument, so that the measuring instrument can obtain the brightness value and the color temperature value at the same time under the condition that the screen to be tested displays a pure white image, the test duration of the screen to be tested is reduced to a certain extent, and the test efficiency is improved.
Optionally, the at least one test item comprises a first test item and a second test item, and the sending of the optical parameters to be tested corresponding to each test item to the measuring instrument comprises the steps of sending the optical parameters to be tested corresponding to the first test item to the measuring instrument, and sending the optical parameters to be tested corresponding to the second test item to the measuring instrument after the parameter values of the optical parameters to be tested corresponding to the first test item collected by the measuring instrument are obtained.
Illustratively, acquiring the parameter value of the optical parameter to be measured, which is acquired by the measuring instrument, includes actively sending a query message to the measuring instrument or receiving active feedback of the measuring instrument.
In the embodiment, when a plurality of test items are executed, after the test of one test item is finished, the other test item can be executed, so that the mutual interference among the plurality of test items is avoided, and the test accuracy is improved.
In one possible implementation manner, whether the current test item is tested is judged by determining whether the parameter value of the optical parameter to be tested corresponding to the current test item is received, after the test of the current test item is finished, the optical parameter to be tested corresponding to the next test item is sent to the measuring instrument, and the test image corresponding to the next test item is sent to the screen to be tested, so that the measuring instrument can acquire the parameter value of the optical parameter to be tested corresponding to the next test item in the screen to be tested.
It can be understood that the same test item has the corresponding optical parameter to be measured and the measurement image, so that a binding relationship exists between the optical parameter to be measured and the measurement image corresponding to the same test item, for example, a binding relationship of transmission time, etc.
The method includes the steps of sending a test image corresponding to a first test item to a screen to be tested while sending the optical parameter to be tested corresponding to the first test item to the measuring instrument, and not sending the test image corresponding to the first test item to the screen to be tested when the optical parameter to be tested corresponding to the first test item is not sent to the measuring instrument. When the measuring instrument tests the screen to be tested according to the optical parameter to be tested corresponding to the first test item, the screen to be tested is displaying the test image corresponding to the first test item, and the accuracy of the test is ensured.
Optionally, after the parameter value of the optical parameter to be tested corresponding to the first test item collected by the measuring instrument is obtained, the method further comprises the step of sending a deleting instruction to the screen to be tested so that the screen to be tested deletes the test image corresponding to the first test item.
In the embodiment, after the test of one test item is finished, the test image corresponding to the test item in the screen to be tested can be deleted, and compared with the processing mode of covering the test image corresponding to the previous test item when the test image corresponding to the current test item is displayed, the scheme of the application can avoid the mutual influence among the test images corresponding to a plurality of test items, ensure the accuracy of displaying the test image of the screen to be tested, and further improve the accuracy of the test result.
S150, acquiring parameter values of the optical parameters to be measured, which are acquired by the measuring instrument.
After the measuring instrument completes acquisition according to the optical parameters to be measured sent by the industrial personal computer, the parameter values of the acquired optical parameters to be measured are fed back to the industrial personal computer, so that the industrial personal computer records and analyzes related data, and the display performance of the screen to be measured is determined. Or after the industrial personal computer sends the optical parameters to be measured to the measuring instrument, actively inquiring the parameter values of the optical parameters to be measured, which are acquired by the measuring instrument, according to the preset time.
When the size of the screen to be measured is large, the point positions to be measured are relatively large, the data quantity of the acquired parameter values of the optical parameters to be measured is also relatively large, omission is easy during manual recording, and the error probability is high. However, the parameter value of the optical parameter Guan Daice is directly transmitted to the industrial personal computer, so that omission can be avoided, and the reserved data has high precision.
S160, generating a test result of the screen to be tested according to the parameter value of the optical parameter to be tested, wherein the test result of the screen to be tested is used for indicating the display performance of the screen to be tested.
The industrial personal computer analyzes the acquired parameter values of the optical parameters to be tested, and confirms the display performance of the screen to be tested. For example, a test report is generated in which the parameter values of the optical parameters to be measured, the evaluation results of the display performance, and the like are displayed.
For example, when the test item in the test task is a gamma curve test, the corresponding test image is a group of gray-scale images uniformly arranged according to the magnitude order of the gray-scale values, and the difference of the gray-scale values between two adjacent gray-scale images is equal. For example, the test image is a 256 Zhang Huidu chart arranged in accordance with gray values of 0 to 255, the difference in gray values between two adjacent gray charts is 1, or a 128 Zhang Huidu chart arranged in accordance with gray values of 0, 2, 4, 6. The difference in gray values between two adjacent gray maps is equal, and the change in gray is uniform. The collected parameter values of the optical parameters to be measured are brightness values corresponding to the gray level images, wherein the collected parameter values can be brightness values of the same pixel point in different gray level images.
And obtaining a test result of the screen to be tested according to the change trend of the brightness value. For example, the difference value of the brightness values corresponding to two adjacent gray-scale images is obtained, whether each difference value is in an allowable range or not is confirmed, for example, the allowable difference value between gray-scale images with smaller gray-scale values is larger, the allowable difference value between gray-scale images with larger gray-scale values is smaller, if yes, a test result of a screen to be tested is generated, and the gamma curve test is indicated to be qualified. Or drawing a gamma curve according to the gray value corresponding to the gray image and the acquired brightness value, and confirming whether the parameter value of the gamma curve is in an allowable range, if so, generating a test result of the screen to be tested, and indicating that the gamma curve is qualified in test.
In addition, when the acquired parameter value of the optical parameter to be measured and the preset standard value are different from each other by more than a preset threshold value, whether the measured environment is abnormal or not is confirmed. The test can be performed again after the environmental factors are eliminated.
According to the method, a test task is acquired according to a test item selected by a user, a test image corresponding to the test item is sent to a screen to be tested, and an optical parameter to be tested corresponding to the test item is sent to a measuring instrument, so that when the test image corresponding to the test item is displayed on the screen to be tested, the measuring instrument tests the screen to be tested of the current display test image, acquires a parameter value of the optical parameter to be tested corresponding to the test item, and generates a test result of the screen to be tested according to the parameter value of the optical parameter to be tested acquired by the measuring instrument, and the display performance of the screen to be tested is indicated. In the method, on one hand, the test method does not need manual intervention, so that a test image corresponding to the test item can be sent to the screen to be tested based on the test item in the test task, and the optical parameter to be tested corresponding to the test item can be sent to the measuring instrument based on the test item in the test task, thereby realizing automatic test on the screen to be tested, reducing the labor investment and improving the test efficiency; on the other hand, in the scheme, when a screen to be tested is tested, a test image corresponding to each test item and a parameter value of an optical parameter to be tested can be obtained for each test item in at least one test item, the pertinence test of the test items is realized through the parameter values of the test image corresponding to each test item and the optical parameter to be tested, the obtained test result of each test item is more accurate, the accuracy of the test result of the screen to be tested can be improved through improving the accuracy of each test item, and the accuracy of the screen test is improved on the premise of ensuring the test efficiency of the screen.
