In this embodiment, it should be noted that, referring to fig. 2, the quality detection device may include a test platform G110, the camera G120, a power control G130, and the display screen G140 to be tested, where the test platform may be a SkyRobot automatic test platform, where the test platform is used to control the power control to perform cyclic power on/off, the camera is used to capture display screen images of the display screens to be tested, and the quality detection device may detect the display screen quality of a plurality of display screens to be tested at the same time, that is, the quality detection device may set the same number of cameras and the same number of power switches as the display screens to be tested at the same time, in fig. 2, only two display screens to be tested are listed, and in order to further ensure accuracy of quality detection of the display screens, thousands of on/off detection and screen detection may be performed on each display screen to be tested; the switching on/off detection result can comprise switching on/off time length information and switching on/off stability information, and is used for representing switching on/off performance of each display screen to be detected; the image similarity can be understood as an evaluation index of the quality of the display screen, and is used for performing screen detection on the display screen to be detected, namely judging whether the display screen to be detected has a black screen or a patterned screen.
As an example, steps S10 to S40 include: if the display screens to be detected are detected to be placed on the detection platform, the quality detection request signals can be triggered by clicking a start detection button on the detection platform, and when the quality detection request signals are received by the test platform, power control corresponding to the display screens to be detected are controlled to carry out circulating power on-off so as to carry out on-off detection, and corresponding on-off duration information and corresponding on-off stability information are obtained; if the display screens to be tested are started normally, controlling cameras corresponding to the display screens to be tested to shoot images, and obtaining corresponding display screen starting images; invoking a third party test library such as sikuli, directly calculating the image similarity of each display screen image, and carrying out screen detection on the corresponding display screen to be detected according to each image similarity so as to judge whether the display screen to be detected has a black screen or a flower screen, thereby obtaining a corresponding screen detection result, wherein the screen detection result comprises a black screen detection result and a flower screen detection result; obtaining the black screen frequency information corresponding to the black screen detection result, and inquiring the corresponding quality grade in a preset quality evaluation table according to the black screen frequency information, the flower screen frequency information, the on-off time length information and the on-off stability information, wherein the quality grade is obtained according to four evaluation indexes including the black screen frequency information, the flower screen frequency information, the on-off time length information and the on-off stability information, and can comprise high quality, medium quality and low quality.
The screen detection result comprises a black screen detection result and a splash screen detection result, and the step of carrying out screen detection on the corresponding display screen to be detected according to the image similarity to obtain the corresponding screen detection result comprises the following steps:
the step of controlling cameras corresponding to the display screens to be detected to acquire images based on the on-off detection results to obtain images of the display screens comprises the following steps:
step S21, starting a waiting mode based on each switching on/off detection result;
step S22, obtaining the waiting time length corresponding to the waiting mode, and detecting whether the waiting time length reaches a preset waiting time length or not;
and S23, if yes, controlling each camera to acquire an image, and acquiring a corresponding display screen image.
In this embodiment, it should be noted that, since other images, such as a product LOGO image, will appear on the display screen to be tested in the starting process, and the display screen image collected in this embodiment is a display screen starting image, that is, an initial image of the display screen to be tested after normal starting, only after the user performs remote control or language operation, the initial image will change, so as to further ensure accuracy of quality detection of the display screen, in this embodiment, a preset waiting period is set, and a purpose of ensuring that the captured display screen image is the initial image is achieved.
As an example, steps S21 to S23 include: if the detection results of the on-off states are obtained, and the display screens to be detected are normally started at the moment, starting a waiting mode, wherein the waiting mode refers to that the quality detection equipment pauses a quality detection flow until waiting time corresponding to the waiting mode reaches preset waiting time, and the preset waiting time is a time experience value set by a person skilled in the art according to the product performance of the display screens to be detected, namely, how long an initial image can appear on the display screens to be detected; and when the waiting time length reaches the preset waiting time length, starting a subsequent quality detection flow, namely controlling each camera to acquire images, and acquiring corresponding display screen images.
For example, assuming that the preset waiting time is 75 seconds, when the display screen 1 to be tested is started normally, the detection platform enters a waiting mode until the waiting time reaches 75 seconds, and the camera corresponding to the display screen 1 to be tested is controlled to shoot the display screen image.
The step of obtaining the image similarity of each display screen image comprises the following steps:
step S31, detecting whether each display screen image is a preset normal display screen image;
Step S32, if yes, similarity detection is carried out on each display screen image, and corresponding image similarity is obtained;
and step S33, if not, performing system early warning.
In this embodiment, it should be noted that, before performing the similarity detection, it is required to determine whether each display screen image is a preset normal display screen image, if each display screen image is displayed abnormally, for example, the displayed image is incomplete or a black-and-white image is displayed, to indicate that at this time, the display fault occurs in each display screen to be detected, and then early warning is directly performed, and the specific flow can refer to fig. 3, and no subsequent similarity detection is performed, so that storage resources for quality detection are saved, and efficiency of quality detection of the display screen is improved; the preset normal display screen image is an initial picture image of the display screen to be tested after normal startup.
As an example, step S31 to step S33 include: comparing each display screen image with the preset normal display screen image to detect whether each display screen image is the preset normal display screen image or not; if yes, the display screens are normally started, and similarity detection is carried out on the images of the display screens to obtain corresponding image similarity; if not, indicating that the display fault occurs in each display screen at the moment, and carrying out system early warning.
Step S34, detecting whether a corresponding display screen to be detected has a black screen or not according to the similarity of the images;

and step S37, if the screen is in the presence, recording the current screen display picture of the display screen to be detected and the corresponding second timestamp as the screen display detection result, and carrying out screen display early warning.
As an example, steps S34 to S37 include: detecting whether a corresponding display screen to be detected appears in a black screen or not according to the image similarity and a preset first similarity, wherein the preset first similarity is a similarity value of the black screen which is preset according to iteration information and product performance of the display screen to be detected, and the similarity value is an empirical value and can be adjusted according to actual conditions; if the black screen appears, recording a current black screen picture of the display screen to be detected and a corresponding first timestamp as the black screen detection result, sending mails to related managers for early warning, and carrying out light early warning or voice broadcasting early warning, wherein the early warning form is not limited, and the first timestamp refers to the current time corresponding to the current black screen picture; if no black screen appears, further detecting whether a corresponding display screen to be detected appears a splash screen according to the image similarity and a preset second similarity, wherein the second similarity value is a similarity value indicating that the splash screen appears, and the specific meaning of the second similarity value is the same as that of the preset first similarity value; if the screen is in a pattern, recording a current screen pattern of the display screen to be detected and a corresponding second timestamp as a screen pattern detection result, and sending mails to related managers for screen pattern early warning, wherein the second timestamp is the current time corresponding to the current screen pattern, and if the screen pattern is not in the current time, the display screen to be detected is in a black screen or a pattern, and the display screen to be detected is normal.
The step of detecting whether the corresponding display screen to be detected has a black screen or not according to the similarity of the images comprises the following steps:
step S311, detecting whether the similarity of each image is larger than a preset first similarity;
step S312, if yes, judging that the corresponding display screen to be tested does not have a black screen;
step S313, if not, judging that the corresponding display screen to be tested is black.
As an example, step S311 to step S313 include: detecting whether the similarity of each image is larger than a preset first similarity; if the similarity of each image is larger than the preset first similarity, judging that the corresponding display screen to be tested does not have a black screen, and further detecting whether the display screen to be tested has a pattern screen or not; if the image similarity is smaller than or equal to the preset first similarity, judging that the corresponding display screen to be tested is black, recording the current black screen picture and the corresponding first timestamp, and carrying out early warning.
For example, referring to fig. 4, assuming that the preset first similarity is 0.7 or 70%, if the image similarity of the display screen 1 to be measured is calculated to be 0.65 and smaller than 0.7, it is determined that the display screen 1 to be measured has a black screen, and the black screen picture and the current computer time at that time are recorded and early warning is performed; if the image similarity of the display screen 1 to be detected is calculated to be 0.8 and is larger than 0.7, judging that the display screen 1 to be detected does not have a black screen, and further detecting whether the display screen 1 to be detected has a patterned screen or not.
The step of detecting whether the corresponding display screen to be detected has a screen pattern according to the similarity of the images comprises the following steps:
step S331, detecting whether the similarity of each image is larger than a preset first similarity;
step S332, if yes, judging that the corresponding display screen to be tested does not have a black screen;
step S333, if not, judging that the corresponding display screen to be tested is black.
As an example, steps S331 to S333 include: detecting whether the similarity of each image is larger than a preset second similarity; if the similarity of each image is larger than the preset second similarity, judging that the corresponding display screen to be tested does not have a black screen, and further detecting whether the display screen to be tested has a pattern screen or not; if the image similarity is smaller than or equal to the preset first similarity, judging that the corresponding display screen to be tested is black, recording the current black screen picture and the corresponding first timestamp, and carrying out early warning.
For example, referring to fig. 4, assuming that the preset second similarity is 0.94 or 94%, if the image similarity of the display screen 1 to be measured is calculated to be 0.8 and less than 0.94, determining that the display screen 1 to be measured has a screen pattern, recording the screen pattern picture and the current computer time at that time, and performing early warning; if the image similarity of the display screen 1 to be measured is calculated to be 0.99 and is larger than 0.94, judging that the display screen 1 to be measured does not have a screen pattern, and indicating that the display screen 1 to be measured is normal.
The on-off detection result comprises on-off time length information and on-off stability information, and the step of determining the quality grade of the corresponding display screen to be detected according to the screen detection results and the on-off detection results comprises the following steps:
step S41, obtaining the black screen frequency information corresponding to each black screen detection result and the flower screen frequency information corresponding to each flower screen detection result;
step S42, matching the quality grade of the corresponding display screen to be tested in a preset quality evaluation table according to the black screen frequency information, the screen pattern frequency information, the on-off time information and the on-off stability information.
In this embodiment, it should be noted that the on-off duration information refers to an average on-time of each display screen to be tested; the on-off stability information refers to the stability of the starting time of each display screen to be detected, wherein the stability of the starting time refers to standard deviation obtained by normally distributing the starting time of each display screen to be detected; the black screen frequency information is used for representing the frequency of the black screen of each display screen to be tested; the screen display frequency information is used for representing the frequency of the screen display of each display screen to be tested; in order to better evaluate the quality of the display screen, the preset quality evaluation table may be established, and referring to fig. 5, the preset quality evaluation table is used for evaluating the quality level of each display screen to be tested according to four evaluation indexes of the black screen frequency information, the screen-pattern frequency information, the average starting time and the starting time stability, and making a corresponding evaluation rule, for example, when the black screen frequency is 0, the screen-pattern frequency is 0, the average starting time is 70 seconds and the starting time stability is less than or equal to 5 seconds, the quality level is high, the black screen frequency is 0, at most 1 screen-pattern occurs, when the average starting time is 80 seconds and the starting time stability is less than or equal to 10 seconds, the quality level is medium quality, at most 1 screen-pattern occurs, and when the average starting time is 90 seconds and the starting time stability is less than or equal to 20 seconds, the quality level is low quality. Reference is made in particular to fig. 2.
As an example, step S41 to step S42 include: acquiring the recording times of each current black screen picture, taking the recording times as the black screen times, acquiring the recording times of each current splash screen picture, and taking the recording times as the splash screen times; and matching corresponding quality grades in the preset quality evaluation table according to the black screen frequency information, the screen pattern frequency information, the average starting time and the starting time stability.
After the step of determining the quality level of the corresponding display screen to be tested according to the screen detection results and the on-off detection results, the method further comprises the following steps:

and step A20, the data packet is sent to a preset display platform, and the preset display platform is used for visually displaying the data packet.
In this embodiment, it should be noted that, because in the prior art, the quality detection of the display screen is performed by using a manual detection manner, in order to improve the intelligence of the quality detection of the display screen, in this embodiment, the screen detection result, the on-off detection result and the quality level of each display screen to be detected are selected to be visualized in a preset display platform, so as to achieve the purpose of remotely observing the quality detection result of each display screen to be detected; referring to fig. 2, the preset display platform may be an online skygafana display system, which includes a display screen real-time display module G510/G520 and a mysql database G530, where the display screen real-time display module is configured to call a data packet in the mysql database and display the content in the data packet, and the mysql database stores the data packet corresponding to each to-be-detected display screen transmitted by the quality detection device, and a specific visual schematic may refer to fig. 6.
As an example, steps a10 to a20 include: packaging screen detection results corresponding to the display screens to be detected, corresponding on-off detection results and corresponding quality grades to obtain quality detection data packets corresponding to the display screens to be detected; and sending each quality detection data packet to a preset display platform so that the preset display platform can analyze each quality detection data packet, and visualizing a screen detection result corresponding to each display screen to be detected, a corresponding on-off detection result and a corresponding quality grade according to each first timestamp and each second timestamp in the data packet according to the time sequence, so that related management staff can intuitively and clearly know the quality condition of each display screen to be detected.
