Document Type and Number:
WIPO Patent Application WO/2022/222650
Kind Code:
A1
Abstract:
A method for classifying a glass object (200) via acoustic analysis by a classifying apparatus (100) is provided. The method including: receiving, by a processor (110), sound data of a knock sound generated by applying a knocking operation on the glass object (200)(S210); determining, by the processor (110), a type of the glass object (200) by performing a knock-sound analysis to the sound data, wherein the type of the glass object (200) includes an organic glass and an inorganic glass (S220); if the type of the glass object (200) is determined as the inorganic glass, receiving, by the processor (110), echo data of an echo induced by applying an ultrasonic-echo operation on the glass object (200)(S230); and determining, by the processor (110), a further type of the glass object (200) by performing an echo-decay analysis to the echo data, wherein the further type of the glass object (200) includes a crystal glass, a borosilicate glass and a soda-lime glass (S240).
