Washing machine vibration fault detection method and device

Abstract

The present disclosure provides a washing machine vibration fault detection method and device. The method comprises the following steps of determining a standard vibration mode according to a vibration detection type option selected by a user; acquiring a target video corresponding to a washing machine; amplifying the target video by adopting a Lagrange motion amplification method to obtain an amplified output video; acquiring image frames corresponding to the amplified output video, and calculating cross power spectrum between image frames by adopting a phase correlation algorithm for the image frames; performing inverse Fourier transform on the cross power spectrum to obtain vibration information of pixels in the target video; and matching the vibration information with the vibration information corresponding to the standard vibration mode, and determining the vibration fault of a vibrating object according to the matching result. By adopting the embodiment of the application, the Lagrange motion amplification method is adopted to amplify the micro motion in the video, and then the vibration information in the video is extracted, so that the accuracy of information extraction isimproved, and the reliability of vibration analysis is further improved.

Description

technical field [0001] The disclosure relates to the field of machine learning, in particular to a method and device for detecting vibration faults of a washing machine. Background technique [0002] Internet The Internet belongs to the media field, also known as the international network, which is a huge network formed by connecting networks. These networks are connected by a set of common protocols to form a logically single huge international network. This method of interconnecting computer networks can be called "network interconnection". On this basis, a global Internet covering the whole world is developed called the Internet, which is a network structure that is interconnected. "Internet +" is a new form of Internet development under Innovation 2.0, an evolution of the Internet form driven by Knowledge Society Innovation 2.0 and a new form of economic and social development that it has spawned. "Internet +" is a further practical result of Internet thinking, which pr...

Problems solved by technology

However, since the vibration process is very subtle, many vibration situations are difficult to observe with the naked eye, and an effective method is needed to amplify the vibration video to facilitate the extraction of vibration information for further analysis
