Abstract

The invention discloses a signal processing method, a signal processing device and a related product. The signal processing method comprises the following steps: acquiring a plurality of state changesignals corresponding to a cross-cross power spectrum obtained by performing phase correlation calculation on a frame sequence corresponding to a detection video, wherein the state change signals aretime domain signals; analyzing the plurality of state change signals to obtain non-periodic signals in the plurality of state change signals; and removing an aperiodic signal of the plurality of statechange signals. In this way, more useful information is obtained from the state change signals obtained from the detection video, and therefore the operation condition, obtained according to the detection video, of the to-be-detected device can be more accurate.

Description

technical field [0001] The invention relates to the technical field of detection, in particular to a signal processing method, device and related products. Background technique [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, and then obtain the vibration of the device to be detected from the video. When extracting the vibration signal, you can first extract each pixel in the video. The state change signal of the point, and then the vibration of the device to be detected is obtained according to the state change signal. However, when shooting a video, it will be affected by the environment and introduce various noise information. For example, the light will also cause the vibration of each pixel in the video. If the state changes, the obtained vibration situation of the device to be detected also includes noise information, which makes ...
