Problems solved by technology

[0002] In related technologies, vibration can reflect the operating conditions of certain mechanical structures. It is possible to take a video of the vibration device when it is running, then extract the vibration signal from the video, and then obtain the operating status of the device according to the vibration signal. However, when shooting the video, A variety of noise information will be introduced due to the influence of the environment, and the vibration signal extracted from the video also contains a large number of noise signals, which makes it impossible to accurately obtain the operating status of the device

Abstract

The invention discloses a filtering method, a filtering device and a related product. The filtering method comprises the steps of obtaining one or more correlation peaks obtained by performing phase correlation calculation on a frame sequence corresponding to a detection video, wherein the correlation peaks are frequency domain signals; determining a filtering strategy corresponding to each correlation peak according to the corresponding position of each correlation peak in the detection video and the frequency band corresponding to the correlation peak; and performing filtering processing oneach correlation peak according to the filtering strategy corresponding to each correlation peak. The appropriate filtering strategy is selected for filtering according to the position of each correlation peak and the corresponding frequency band, so that the noise information in each correlation peak can be reduced, the signal to noise ratio of the frequency signal obtained from the detection video is higher, and the operation condition of the to-be-detected device obtained according to the detection video is more accurate.
