WASHING MACHINE VIBRATION FAULT DETECTION METHOD AND APPARATUS

摘要

Provided is a washing machine vibration fault detection method, comprising: determining a standard vibration mode according to a vibration testing type option selected by a user (102); acquiring a target video corresponding to a washing machine (103); amplifying the target video by using a Lagrange motion amplification method to obtain an amplified output video (104); acquiring image frames corresponding to the amplified output video, and calculating a cross power spectrum between the image frames by applying a phase correlation algorithm to the image frames (105); performing an inverse Fourier transform on the cross power spectrum to obtain vibration information of pixels in the target video (106); and matching the vibration information and vibration information corresponding to the standard vibration mode, and determining a vibration fault of a vibrating object according to a matching result (107). The Lagrange motion amplification method is used for amplifying a micro motion in a video, and vibration information in the video is then extracted, so that the accuracy of information extraction is improved, and the reliability of vibration analysis is thus also improved. Further provided is a washing machine vibration fault detection apparatus.
