Step S20, continuously acquiring corresponding output audio when the audio and video equipment plays the original test audio, and converting the output audio into an output audio curve;
and acquiring the output Audio played currently in real time, and converting the output Audio into an output Audio curve through Audio Precison. It will be appreciated that instead of obtaining the output audio in real time, the entire output audio may be directly converted into an output audio profile. Furthermore, besides curves, the visual image converted from the original test audio and the output audio can also be combined to form the visual image corresponding to the audio by setting preset time intervals, taking one or more sampling points in each preset time interval and combining all the sampling points.
And step S30, performing image recognition comparison on the output audio curve and the original test audio curve to judge whether the audio and video equipment is abnormal or not according to the comparison result.
When the output audio curve and the original test audio curve are converted, an alignment mark can be set on the output audio curve and the original test audio curve so as to avoid the deviation of the output audio curve and the original test audio curve during image recognition and make a test result wrong.
It can be understood that the method is suitable for testing audio and video hardware equipment and can also be suitable for testing audio and video software by converting the original test audio and the output audio into audio curves, judging whether the software in the equipment is abnormal or not by comparing the original test audio curve with the output audio curve and judging whether the equipment is abnormal or not according to the judgment result of whether the software is abnormal or not.
In the embodiment, an original test audio is obtained and converted into an original test audio curve; continuously acquiring an output audio corresponding to the original test audio played by the audio and video equipment, and converting the output audio into an output audio curve; and carrying out image recognition comparison on the output audio curve and the original test audio curve so as to judge whether the audio and video equipment is abnormal or not according to a comparison result. The related parameters of the output audio and the test audio are patterned into a sound curve, and the curve is subjected to automatic graph comparison, so that the high efficiency and accuracy of the test requirement are met, and a large amount of manpower and time are saved.
Further, in a second embodiment of the method for testing an audio/video device of the present invention proposed based on the first embodiment of the present invention, the step S10 includes the steps of:
step S11, converting the original test audio into an original test audio curve with the test parameters and the playing time as coordinates;

step S21, converting the output audio into an output audio curve with the test parameters and the playing time as coordinates.
The measurement of an audio frequency can be performed through various test parameters, such as frequency response, sound mode, left and right channel separation, accompanying sound power, signal-to-noise ratio, distortion degree, high and low tones, left and right channel gain difference, sound effect, frequency response range, and the like. For each test parameter, the audio may be converted to a corresponding audio curve. In this embodiment, according to the test requirement, a plurality of test parameters of the original test audio and the output audio are selected, a coordinate system is established with the test parameters as vertical coordinates and the playing time as horizontal coordinates, and an original test audio curve and an output audio curve are generated with the coordinate system.

comparing the original test audio curve and the output audio curve frame by frame through an image recognition tool.
After the original test audio curve and the output audio curve are obtained, frames of the original test audio curve and the output audio curve at the same playing time are compared through an image recognition tool, and then test parameter values corresponding to the frames are compared. It will be appreciated that in making the comparison, a single frame of the curve image may be selected for comparison, or a section of the curve may be selected for comparison.
The difference between the original test audio curve and the output audio curve is compared through an image recognition tool, so that the audio file can be made to be data through audio visualization, and automatic audio testing can be carried out according to the data.
Further, the step of determining whether the audio/video device is abnormal according to the comparison result in S30 includes:
obtaining a difference value between the corresponding test parameters of each playing time in the output audio curve and the original test audio curve according to the comparison result;
sequentially judging whether the difference value between the test parameters corresponding to each playing time is greater than a preset threshold value or not;
and when the difference value is judged to be larger than the preset threshold value, determining that the output audio and video equipment is abnormal.
Because the original test audio and the output audio are visualized to generate an original test audio curve and an output audio curve, whether the original test audio curve and the output audio curve are abnormal can be judged directly by judging whether the difference value of the test parameters of the corresponding frames of the original test audio curve and the output audio curve at the same playing time exceeds the allowable error range, namely the preset threshold value.
And judging whether the abnormality exists or not through the difference value between the test parameters corresponding to each playing time in the output audio curve and the original test audio curve, and clearly and visually displaying the abnormality of the output audio curve to the original test audio curve.

when the difference value is judged to be less than or equal to the preset threshold value, detecting whether the playing time corresponding to the current difference value is the playing ending time of the original test audio;
if not, continuing to execute the judgment operation of whether the next difference value is larger than the preset threshold value;
if yes, stopping the test.
And when the frames corresponding to the current original test audio curve and the output audio curve are determined to be not abnormal, judging whether all the frames to be tested of the detection task are tested, and stopping continuously testing and waiting for user operation when all the frames to be tested of the detection task are determined to be tested.
It can be understood that, when the frames corresponding to the original test audio curve and the output audio curve are tested to be abnormal, the pause operation may not be executed, the test is paused after all the tests are completed, and all the abnormal log test files in the test process are output together for the user to debug.
When the single test result is not abnormal, the test of the next frame is automatically carried out, and the automatic test operation is realized.
Further, before the step of continuing to execute the operation of determining whether the next difference is greater than the preset threshold, the method further includes:
if not, deleting the curve segment of the current difference value corresponding to the output audio curve.
And when the current curve segments of the original test audio curve and the output audio curve are determined to be abnormal, deleting the corresponding curve segments in the output audio curve. Memory space is saved.
Further, the method further comprises;
and when the test is stopped or the output audio and video equipment is determined to be abnormal, storing the test log file.
Further, after the step of saving the test log file, the method further includes:
and under the condition that the test log file is stored when the output audio and video equipment is determined to be abnormal, outputting the test log file for debugging by a user.
And when the original test audio curve and the output audio curve are not detected to be abnormal, outputting the log file for the user to check. And when the original test audio curve and the output audio curve are detected to be abnormal, suspending the test, storing and outputting a log file containing the positions of the abnormal curves in the original test audio curve and the output audio curve, and waiting for debug (abnormal debugging) of a user.
When the test is finished or the abnormity occurs, the test log file is stored and output for debugging by the user, and the test log file contains abnormity positioning, so that the user can find the abnormity quickly.
Further, the test result can be output after the test is finished, and when the original test audio curve and the output audio curve are not found to have abnormality, abnormal information such as PASS is displayed; when the original test audio curve and the output audio curve are found to have abnormality, abnormal information such as FAIL is displayed.
