Reference-supervised vision-based vibration measurement and time–frequency enhancement for variable-speed bearings under coarse ROI localization

To address the issues of Region of Interest (ROI) sensitivity, background interference, and unclear time–frequency structures in visual vibration analysis of variable-speed rolling bearings, this article proposes a loosely localized ROI-based visual vibration recovery and multiscale time–frequency enhancement method un...

Vision-based vibration measurement and compound defects feature extraction for rolling bearings based on multi-frequency phase

High-speed cameras have been widely adopted as a non-contact alternative to conventional contact sensors for mechanical condition monitoring. Traditional image spatial filtering faces two challenges: selecting a appropriate spatial frequency parameter, and phase wrapping caused by the arctangent function’s principal-va...
