Embodiment 1
[0043] According to an embodiment of the present application, a video detection method is provided, and the method is applied to a TV board test.
[0044] Combine below figure 1 The video detection method provided in the embodiment of the present application is introduced in detail. like figure 1 As shown, the method includes the following steps:
[0045] Step S102, obtaining a test video stream and a reference video stream;
[0046] The test video stream may be a video stream output by a TV board to be tested, and the reference video stream may be a video stream output by a standard TV board. The two TV boards output the same video stream, and there is no abnormality in each video frame contained in the reference video stream, so by comparing each video frame in the test video stream with the corresponding video frame in the reference video stream, It is possible to determine whether the video frames in the test video stream are abnormal.
[0047] In order to obtain the ...
Embodiment 2
[0059] like figure 2 As shown, the video detection method includes the following steps:
[0060] Step S202, acquiring multiple sets of sample data, wherein each set of sample data includes: a first video frame, a second video frame, and a similarity between the first video frame and the second video frame;
[0061] In order to be able to train the siamese network with the highest accuracy, 120,000 two-way synchronous queues and data can be collected, of which the positive and negative sample pairs account for 50% each. The current frame and the reference frame are negative sample pairs.
[0062] Optionally, as in image 3 As shown, the sample collection method is described as follows: through an RF signal attenuator in front of the board to be tested, the RF signal is attenuated according to the attenuation range ranging from 1db to 10db, and a mosaic will appear at the stream end to be tested. Abnormal picture; start the signal attenuator button at an interval of 5s, and ...
Embodiment 3
[0112] According to an embodiment of the present application, a video detection method is provided, and the method is applied to a TV board test. like Image 6 As shown, the method includes the following steps:
[0113] Step S502, obtaining a test video stream and a reference video stream;
[0114] Step S504, performing synchronous processing on the test video stream and the reference video stream, and determining the target offset;
[0115] In this embodiment, the method of determining the target offset is as follows: the video frame in the reference video stream is compared with the video frame in the test video stream to determine the first offset, wherein the first offset is used for Characterize the offset of the video frame in the test video relative to the video frame in the reference video stream; according to the first offset, compare the video frame set in the reference video stream with the video frame set in the test video stream to determine The second ...
