Zusammenfassung: | The invention discloses a vibration measurement method, system and device based on laser speckles and a storage medium. The method comprises the following steps: acquiring a plurality of laser speckle patterns of a vibrating object collected according to a preset time interval within a preset time period; performing quality evaluation on the plurality of laser speckle patterns, and screening out a target laser speckle pattern meeting a preset requirement; and calculating speckle pixel displacement according to the target laser speckle pattern, determining a vibration inclination angle according to the speckle pixel displacement, and determining the vibration frequency of the vibration object according to the vibration inclination angle. The embodiment of the invention belongs to the technical field of measurement, and can be widely applied to more accurately measuring the vibration information of the object.
