Hereinafter, the screen detecting method provided by the present application will be described in detail by specific embodiments.

Referring to fig. 2, an embodiment of the present application provides a screen detection method, which is executed in an electronic device a for detecting whether a screen of an object to be detected has problems such as screen splash and/or screen splash, and the method includes:

step 202, a first image sequence and a second image sequence are acquired.

The second image sequence comprises a screenshot image of second electronic equipment, the second electronic equipment is an object to be detected, the first image sequence comprises a screen display image of first electronic equipment, and the first electronic equipment is a reference object of the object to be detected and has good screen display capacity.

The first electronic device and the second electronic device compress the image sequence before sending the image sequence to the electronic device a, and the electronic device a decompresses the compressed content correspondingly after receiving the image sequence from the first electronic device and the second electronic device, so as to obtain a final first image sequence and a final second image sequence.

Here, the content is not necessarily limited to the application scenario, and the same content is executed for the first electronic device and the second electronic device in any application scenario. Because the first electronic device and the second electronic device are terminals of the same type, and have display screens with the same size and the same specification, and the first electronic device has a good screen display capability, the screen display image of the first electronic device is the actual display content of the operating content in the application scene, in other words, the screen display image of the first electronic device is the content that the second electronic device should display under the condition that the screen is free of failure.

Therefore, the electronic device a can shoot a real-time screen display image of the first electronic device to obtain a first image sequence, and intercept a real-time screen capture image of the second electronic device to obtain a second image sequence, and the first image sequence is used as a reference standard of the second image sequence.

The second electronic device is preset with an application program controllable by the electronic device a, so that the electronic device a can control the application program to capture a screenshot of the second electronic device while shooting the screen display image of the first electronic device, and the obtained screenshot image is the same image as the screen display image of the first electronic device at the same time.

Step 204, adjusting the attribute information of each first image in the first image sequence to align each first image with a second image having the same timestamp in the second image sequence.

The attribute information of the image includes, but is not limited to, a timestamp, an image shape, an image brightness, and the like, and since the first image is formed by shooting by the electronic device a, the image shape and the image brightness of the first image have a certain difference from a screen display shape and a screen brightness situation of the first electronic device due to factors such as a shooting environment and a shooting angle.

The second image with the same time stamp in the second image sequence and the first image are shot at the same time and have the same content, the second image is generated by screenshot, the size of the second image is consistent with the size of the screen display of the second electronic device, the shape of the image is standard, and the brightness of the image cannot be influenced by the external environment. Therefore, the corresponding second image can be used as the first image for fine adjustment of the image, negative effects caused by external factors such as a shooting environment, a shooting angle and the like can be reduced by fine adjustment of attribute information of the first image, and the accuracy of a screen detection result can be further improved.

Step 204 is described in detail below.

In one possible design, the attribute information includes a timestamp and a screen shape.

In another possible design, the attribute information includes a timestamp and screen brightness.

In another possible design, the attribute information includes a timestamp, screen brightness, and screen shape.

First, the attribute information must include a timestamp, and step 204 includes: a second image having the same time stamp is determined in the second image sequence for each first image in the first image sequence.

Before preprocessing the first image, such as image brightness, image shape and the like, the first image sequence and the second image sequence are required to be in one-to-one correspondence according to the time stamps of the images, the first image and the second image with the same time stamp are the images shot at the same moment and can be mutually used as references, namely the second image is used as a reference for adjusting the attribute information of the first image, so that the first image is closer to the actual display effect of the first image, and the adjusted first image is used as a comparison reference of the second image to judge whether the second electronic device where the second image is located has screen failure.

Next, the image shape and/or image brightness is adjusted.

The image shape is adjusted by the following method: and performing affine transformation on each first image by taking the second image corresponding to each first image in the first image sequence as a fitting object, so that the image shape of each first image is consistent with that of the corresponding second image.

Affine transformation is linear transformation from two-dimensional coordinates to two-dimensional coordinates, straightness and parallelism of two-dimensional figures are kept, the straightness is kept, namely straight lines or straight lines, circular arcs or circular arcs after transformation is carried out, the parallelism keeping is kept, namely the relative position relation between the two-dimensional figures is kept unchanged, and intersection angles of parallel lines or parallel lines and intersected straight lines are kept unchanged. That is, the first image can be given the same shape as the first image by affine transformation without changing the substantial pixel distribution of the first image, facilitating further comparison with the first image.

The image brightness adjustment mode is as follows: and adjusting the image brightness of each first image in the first image sequence to enable the ratio of the image brightness of each first image to the image brightness of the corresponding second image to be a specified coefficient.

Because the first image is obtained by shooting, the whole brightness of the first image is different from that of the second image, and in order to reduce the difference, the first image can restore the real display effect as much as possible and become an effective reference, and the brightness of the second image can be adjusted. Specifically, the image brightness of the second image may be adjusted to a level at which the ratio to the image brightness of the second image is a specified coefficient. In the contrast of the luminance curves in the following steps, as long as the luminance ratio of the first image to the second image is a prescribed coefficient, the two may have the same luminance curve in the case where the second electronic device has no screen failure.

In one possible design, a coefficient of 1 is specified, and the first image and the second image may have coinciding luminance curves without a screen failure of the second electronic device.

And step 206, comparing the first image sequence with the second image sequence according to a specified comparison mode to obtain difference information.

And step 208, when the difference information meets the specified condition, identifying that the second electronic equipment has a fault corresponding to the specified comparison mode.

The designated comparison mode comprises a screen splash comparison mode and/or a screen splash comparison mode, and of course, the designated comparison mode can also comprise a comparison mode required for detecting any other screen faults.

In a possible design, the way of the screen-splash comparison is that images in two sequences are compared frame by frame, specifically, a difference threshold between each first image in the first image sequence and the corresponding second image may be calculated, accordingly, the specified condition in the way of the screen-splash comparison is that the difference threshold is greater than the specified threshold, and in case that any difference threshold is greater than the specified threshold, the screen-splash of the second electronic device is identified.

Different colors may be assigned different values so that for any image, its image threshold may be calculated by including pixels of its different color, while the difference between the image thresholds of the first image and the corresponding second image is the difference threshold. The specified threshold is a maximum difference threshold which can be reached when the two images have the same display effect, so that when the difference threshold of the first image and the corresponding second image is larger than the specified threshold, the difference between the display effect of the first image and the display effect of the corresponding second image is shown, and the first image is displayed completely, the display problem occurs on the second image which has the difference between the display effect of the first image and the display effect of the second image, so that the second electronic device which provides the second image can be judged to generate screen splash.

In one possible design, the splash screen contrast mode is whether the trends of the luminance curves of the two images are significantly different. Specifically, a first luminance profile may be generated based on the image luminance and the timestamp of each first image in the sequence of first images; generating a second brightness curve based on the image brightness and the time stamp of each second image in the second image sequence; and acquiring a difference interval of the second brightness curve relative to the first brightness curve.

That is, the time stamp of each image in the image sequence is used as the abscissa, and the image brightness of each image is used as the ordinate, and the corresponding brightness curve is drawn. If the screen of the second electronic device is intact, the position and trend trends of the luminance curve of the second electronic device and the luminance curve of the first electronic device in the same coordinate system should be the same or substantially similar, and the time interval corresponding to the position where the luminance curve and the luminance curve have difference is the difference interval.

If the second electronic device has the screen flashing fault, the brightness of the second electronic device can generate peak jitter or trough jitter in the difference interval, and therefore, once the difference interval is the peak jitter interval or the trough jitter interval, the screen flashing fault of the second electronic device can be determined.

At this point, whether the second electronic device has a fault such as a splash screen or a splash screen can be judged by using the first electronic device as a reference of the second electronic device.

In this technical solution, as long as the first electronic device and the second electronic device operate in the same application scenario, there is no need to be limited to a specific application scenario, in other words, the electronic device a may control the first electronic device and the second electronic device to operate simultaneously in multiple application scenarios, so as to detect whether the second electronic device does not generate a screen failure in multiple application scenarios. Therefore, the detection scene range of screen detection is enlarged, the automation and the efficiency of screen detection are improved, and the screen detection cost is effectively reduced.

Referring to fig. 3, in the screen detection scenario, a first electronic device and a second electronic device are located in a dark box, and an electronic device a may control the dark box to provide designated shooting environment information, and shoot a screen display image of the first electronic device through a shooting device e in the dark box.

The electronic device a can control the camera bellows to shoot the screen display image of the first electronic device at the appointed moment, and simultaneously control the application program d to shoot the screen capture image of the second electronic device at the appointed moment to obtain the screen capture image of the second electronic device.

Of course, the two functions of controlling the second electronic device to simultaneously run the designated content and capturing the image of the second electronic device at the designated time may be respectively completed by the two application programs, or may be integrated in the same application program, which is not limited herein.

The electronic device a can perform detection on the screen of the second electronic device once every specified time interval, and in each detection process on the screen of the second electronic device, the screen display image of the first electronic device with the specified frame number and the screen capture image of the second electronic device with the specified frame number can be collected, namely the same first image sequence and second image sequence with the specified frame number.

Wherein, the appointed time interval and the appointed frame number can be set and flexibly adjusted according to the actual situation.
