Washing machine vibration fault detection method and device

Abstract

The present disclosure provides a washing machine vibration fault detection method and device. The method includes: determining a standard vibration mode according to the vibration detection type option selected by the user; acquiring a target video corresponding to the washing machine; and using a Lagrangian motion amplification method to amplify the target video , to obtain the enlarged output video; obtain the image frame corresponding to the enlarged output video, and use the phase correlation algorithm to calculate the cross-cross power spectrum between the image frames; perform inverse Fourier transform on the cross-cross power spectrum to obtain the vibration information of the pixels in the target video ; Match the vibration information with the vibration information corresponding to the standard vibration mode, and determine the vibration fault of the vibrating object according to the matching result. By adopting the embodiment of the present application, by using the Lagrange motion amplification method to amplify the micro motion in the video, and then extract the vibration information in the video, the accuracy of information extraction is improved, 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
