Electric fan vibration fault detection method and device

Abstract

The invention provides an electric fan vibration fault detection method and an electric fan vibration fault detection device. The electric fan vibration fault detection method comprises the steps of:acquiring a target video corresponding to a vibrating object which is an electric fan; performing amplification processing on the target video by adopting an Euler motion amplification method, and acquiring an amplified output video having a motion amplification effect of the vibrating object, wherein the motion amplification effect means that the motion condition of the vibrating object in a region where reciprocating motion occurs is amplified in the target video; acquiring a frame sequence corresponding to the amplified output video, and calculating an intersecting cross power spectrum between the frame sequence for the frame sequence by adopting a phase correlation algorithm; performing inverse Fourier transform on the intersecting cross power spectrum to obtain vibration information of pixels in the target video; and matching the vibration information with vibration information corresponding to a standard vibration mode, and determining a vibration fault of the vibrating object according to a matching result. By adopting the electric fan vibration fault detection method and the electric fan vibration fault detection device, the precision of information extraction can be improved, and the reliability of vibration analysis is further improved.
