Referring to fig. 2, in a first embodiment of a touch screen delay detection method according to the present invention, the touch screen delay detection method includes:
and step S10, analyzing the event log sent by the target terminal when the time delay detection request is received.
The step is executed on a touch screen time delay detection device, which may be a PC, a single chip, or the like, and is not particularly limited herein. And when the touch screen delay detection equipment receives the delay detection request, analyzing an event log finally sent by the target. The delay detection request is a starting point for starting to execute detection by the touch screen delay detection device, and the delay detection request may be triggered when a user clicks the touch screen delay detection device, or may be triggered automatically, for example: when the target device is connected, it may be determined that a detection task is started, that is, when the touch screen delay detection device detects that the target device is connected, the delay detection request is automatically triggered. The target terminal is a terminal which needs to perform touch screen time delay detection at this time, and the target terminal may be a mobile device with a touch screen, such as a smart phone, a tablet computer, an e-book reader, or a household appliance device with a touch screen, such as a refrigerator, a washing machine, and the like.
The intelligent device based on various platforms usually has a corresponding debugging mode, such as an Android debugging Bridge (ADB, Android Debug Bridge) of an Android mobile phone, the Android debugging Bridge is essentially a command line window used for interaction between a computer end and a mobile phone end or between the computer end and a simulator end, through the Android debugging Bridge, the touch screen delay detection device can obtain an event log of the Android mobile phone, the event log is a one-to-one event log automatically generated according to an event running in the Android mobile phone, events such as key pressing, display brightness change and touch screen clicking are recorded, the event log of the same type has a specific identifier, and the touch screen delay detection device can know the event occurring in the Android mobile phone in real time through the specific identifier.
And step S20, when the event log is the click event log, sending a recording instruction to a preset camera device, and recording the video with the state change of the target terminal touch screen through the preset camera device.
When the touch screen time delay detection device analyzes and determines that a touch screen click event occurs on the android mobile phone in real time, a recording instruction is sent to a preset image pickup device, wherein the preset image pickup device is a device capable of recording a large number of image frames in unit time, such as a smart phone with a high-speed image pickup function, a high-speed camera and the like, and the description is given only by taking the high-speed camera as an example without specific limitation. The frame rate is the number of frames of pictures that can be acquired by a camera within one second, and is an important performance index for measuring a high-speed camera, such as a common 240fps high-speed camera, where 240fps indicates that the high-speed camera can acquire 240 frames of pictures within 1 second, that is, an event within 1 second can be displayed by 240 frames of pictures, details of a rapidly occurring event can be captured in detail, and it can also be known that the higher the frame rate of the high-speed camera is, the clearer the details of the rapidly occurring time can be captured. The method comprises the steps that a touch screen time delay detection device sends a recording instruction to a high-speed camera, an electronic shutter of the high-speed camera is triggered to start recording a video with a changed state of a touch screen of the android mobile phone, and the video is sent to the touch screen time delay detection device.
And step S30, receiving the video sent by the preset camera device, and performing frame division processing on the video to obtain a frame set.
The touch screen time delay detection equipment receives a video sent by the preset camera device, namely the high-speed camera, and frames the video to obtain a frame set, wherein the frame set is a set formed by sequentially arranging all picture frames in the video.
And step S40, analyzing each picture frame in the frame set to obtain a target picture frame, and taking the relative time of the target picture frame as the time delay time of the target terminal touch screen.
And analyzing each picture frame in the frame set by the touch screen time delay detection equipment, for example, reading an image by using a Python image library and performing processing work. Specifically, for example, by means of Python, two adjacent frames in the frame set are compared group by group as a group to obtain similarity information, for example, a first frame and a second frame in the frame set form a first group, and through algorithm comparison, the similarity of the two frames is n, and n is a value very close to 100%, it can be understood that the similarity usually cannot reach 100% due to the variation of environmental influence factors such as light, and the like, and thereafter, the second frame and a third frame in the frame set form a second group, and through algorithm comparison, the similarity of the two frames is m, if n-m > 1-n, that is, the difference between the similarity of n and m is greater than the difference caused by environmental variation, it can be determined that a screen has changed between the corresponding time point of the second frame and the corresponding time point of the third frame (in detection, in order to distinguish between the frames before and after clicking, a high-pair comparison pure color frame is used as the frames before and after clicking, if the time is white before clicking and black after clicking), the median time between the time point corresponding to the second frame and the time point corresponding to the third frame can be taken, the median time is the relative time in the video time line, and the median time is the time delay of the target terminal touch screen.
In the embodiment, the event log of the target terminal is received and analyzed in real time through the touch screen time delay detection device, when the click event log of the target terminal is received, a recording instruction is sent to the preset camera device, the preset camera device records the video with the changed state of the touch screen of the target terminal, the touch screen time delay detection device receives the video, the video is subjected to framing processing to obtain a frame set, the frame set is analyzed to obtain a target picture frame, the relative time of the target picture frame is used as the time delay time of the touch screen, automatic detection of time delay of the touch screen is achieved, manual operation is greatly simplified, detection errors caused by human factors are avoided, and the accuracy of the time delay detection result of the touch screen is improved.
Further, on the basis of the first embodiment of the present invention, a second embodiment of the touch screen delay detection method of the present invention is provided, where this embodiment is a refinement of step S10, and the touch screen delay detection method includes:
step a1, when receiving the delay detection request, sending a log obtaining instruction to the target terminal to be detected.
Step a2, receiving the event log sent by the target terminal, analyzing the event log, and judging whether the event log is a click event log.
Step a3, when the event log is a click event log, executing the step of sending a recording instruction to a preset camera device, and recording the video with the changed state of the target terminal touch screen by the preset camera device.
When receiving a delay detection request, the touch screen delay detection equipment sends a log acquisition instruction to a target terminal to be detected so as to establish a real-time event stream with the target terminal and receive a real-time event log sent by the target terminal. And after receiving the event log, the touch screen time delay detection equipment analyzes the event log, in the embodiment, the event log is provided with a specific identifier, specific time can be identified through the specific identifier, when the event log is clicked by a touch screen, a recording instruction is sent to a preset camera device, and a video changed by the touch screen of the target terminal is recorded through the preset camera device.
In this embodiment, the touch screen delay detection device receives an event log sent by a target terminal in real time, and sends a recording instruction to the preset camera when receiving a click event log, so as to complete the conversion from an event signal to the recording instruction, so as to trigger the preset camera to record a video with a changed state of the touch screen of the target terminal, thereby realizing automatic detection, simplifying manual operation, and avoiding errors caused by operation.
Further, on the basis of the first embodiment of the present invention, a third embodiment of the touch screen delay detection method of the present invention is provided, where this embodiment is a refinement of step S20, and the touch screen delay detection method includes:
and b1, when the event log is the click event log, stopping receiving the event log sent by the target terminal within a preset time.
And b2, sending a recording instruction to a preset camera device, and recording the video with the state change of the touch screen of the target terminal through the preset camera device.
When the touch screen delay detection equipment analyzes and recognizes that an event log sent by a target terminal is a click event log, stopping receiving the event log sent by the target terminal within a preset time, sending a recording instruction to a preset camera device, and recording a video with a changed state of the touch screen of the target terminal through the preset camera device. It can be understood that, in the process of clicking the touch screen, multiple clicks may be caused by a false touch, multiple click event logs are formed in a short time, and processing pressure is brought to the preset image pickup device and the touch screen delay detection device, so that when the touch screen delay detection device analyzes and recognizes that an event log sent by a target terminal is a click event log, the event log sent by the target terminal is stopped being received within a preset time, so as to solve the problem, wherein the preset time is an artificially estimated period for completing one touch screen delay detection.
In the embodiment, by adding the judgment mechanism, when the event log is the click event log, the event log sent by the target terminal is stopped being received within the preset time, so that the problem that the processing pressure is brought to the preset camera device and the touch screen delay detection equipment by multiple clicks formed by mistaken touch is avoided, and the accuracy of data processing is influenced.
Further, referring to fig. 3, on the basis of the first embodiment of the present invention, a fourth embodiment of the touch screen delay detection method of the present invention is provided, where this embodiment is a refinement of step S40, and the touch screen delay detection method includes:
and step S41, acquiring the touch screen refresh rate of the target terminal and a preset threshold corresponding to the touch screen refresh rate.
The touch screen refresh rate is an important index for measuring the quality of the touch screen of the equipment, the touch screen refresh rate directly relates to the impression of the touch screen of the mobile phone, the current mainstream touch screen refresh rates include 60HZ, 90HZ and the like, and the characteristic represents that the screen of the touch screen can be refreshed for 60 times and 90 times in one second respectively, and it can be understood that the unit screen refresh time of the touch screen with the 60HZ refresh rate is larger than the unit screen refresh time of the touch screen with the 90HZ refresh rate, and the characteristic can influence the time delay detection result of the touch screen.
In the capture of the high-speed camera, the change of the screen before and after clicking is reflected in a gradual change process in the picture frame instead of instantly finishing the change, so a standard is needed for measuring the same and different limits of the two picture frames under different refresh rates, namely a preset threshold value.
The method includes the steps that a touch screen time delay detection device obtains a touch screen refresh rate of a target terminal, a preset threshold table is inquired through screen refresh rate information, the preset threshold table records a relation between the touch screen refresh rate and a corresponding threshold value, so that a preset threshold value is obtained, the preset threshold value is a standard value for judging whether two picture frames are the same, if the similarity of the two picture frames is larger than the preset threshold value, the two picture frames are considered to be the same, if the similarity of the two picture frames is smaller than the preset threshold value, the two picture frames are considered to be different, and in this embodiment, it can be stated that the comparison of the later frame with the previous frame is changed.
Step S42, comparing two adjacent frames from the first frame of the frame set to obtain the similarity of the two corresponding frames.
The touch screen delay detection device compares two adjacent picture frames from a first picture frame, specifically, for example, reading an image by using a Python image library and performing processing work, for example, using an opencv library, a PI L library, a skimage library, and the like, the selection of a specific library is not limited herein, and a more preferable method may be selected according to an actual situation, and the two adjacent frames in the frame set are used as a group to perform group-by-group comparison, so as to obtain the similarity of the two corresponding picture frames.
Step S43, if the similarity of the two frames is greater than the preset threshold, comparing the two adjacent frames of the next group to obtain the similarity of the two corresponding frames.
If the similarity of the two image frames is larger than a preset threshold value, the two image frames are not changed, and the touch screen does not respond to the click event within the time corresponding to the two image frames.
And step S44, when the similarity is smaller than a preset threshold, acquiring the relative time of a later picture frame used in the comparison, and taking the relative time as the time delay time of the target terminal.
If the similarity of the two picture frames is smaller than a preset threshold value, the two picture frames are changed, the former picture frame of the two picture frames is determined not to be the changed picture frame of the touch screen in the last group of comparison, therefore, the picture frame with the later relative time in the comparison is taken as a target frame, the relative time of the target frame is the time delay time of the touch screen, the relative time is the time point of the picture frame in the video time line, and the video time line starts from 0 second, namely the first picture frame.
In this embodiment, by obtaining the refresh rate of the screen to determine the preset threshold for comparing the similarity of the two frames, using different refresh rates to correspond to different preset thresholds, and using the image comparison method to determine whether the change of the two frames occurs within the time period of the two frames, the touch screen delay detection device can perform accurate detection with respect to the screen with different refresh rates, thereby widening the application range of the touch screen delay detection method.
Further, on the basis of the first embodiment of the present invention, a fifth embodiment of the touch screen delay detection method of the present invention is provided, where the present embodiment is a refinement of step S40, and the touch screen delay detection method includes:
and c1, acquiring the touch screen refresh rate of the target terminal and a preset threshold corresponding to the touch screen refresh rate.
And c2, comparing the first picture frame of the frame set with other changed picture frames except the first picture frame in the frame set to obtain the similarity between the first picture frame and the changed picture frame.
And c3, taking the picture frame with the similarity smaller than a preset threshold value with the first picture frame as a target picture frame, acquiring the relative time of the first picture frame, and taking the relative time as the time delay time of the target terminal.
The method for obtaining the refresh rate and the preset threshold of the touch screen and the function thereof have been described in the previous embodiment, and are not described herein again.
The touch screen delay detection device compares a first picture frame of a frame set with other changed picture frames except for the first picture frame sequentially frame by frame (the comparison method is explained in the previous embodiment and is not repeated here), obtains the similarity between the first picture frame and the changed picture frame, takes a changed picture frame with the similarity smaller than a preset threshold value with the first picture frame as a target picture frame, obtains the relative time of the first picture frame, and takes the relative time as the delay time of the target terminal.
In this embodiment, by obtaining the refresh rate of the screen to determine the preset threshold for comparing the similarity of the two frames, using different refresh rates to correspond to different preset thresholds, and using the image comparison method to determine the target frame that changes for the first time, the touch screen delay detection device can perform accurate detection on the target frame according to the screens with different refresh rates, thereby widening the application range of the touch screen delay detection method.
In addition, the screen delay detection method in the fourth embodiment may be implemented in combination with the screen delay detection method in the fifth embodiment, for example, averaging the touch screen delay time obtained in the fourth embodiment with the touch screen delay time obtained in the fifth embodiment as obtaining the one-time touch screen delay time helps to weaken the error generated as a result in one of the fourth and fifth embodiments.
Further, on the basis of the above embodiment of the present invention, a sixth embodiment of the touch screen delay detection method of the present invention is provided, where the sixth embodiment is a step subsequent to step S40, and the touch screen delay detection method includes:
and d1, judging whether the delay time is in a preset time range.
