Title:
物体を識別し選別する方法及び装置
Document Type and Number:
Japanese Patent JP2005515068
Kind Code:
A
Abstract:
A system of identifying and/or sorting of matter including an advancing device ( 101 ) for advancing the matter, a radiation emitting device ( 107 ) serving to emit radiation which is varied by the advancing matter, a detecting arrangement ( 103 ) serving to detect the varied radiation, and an analysing arrangement ( 106 ) serving to analyse the varied radiation. A spectral analyser ( 104 ) serves to detect the varied radiation in a plurality of narrow wavelength bands in the visible spectrum in order to determine the colour and/or composition of the matter. The system may also include another spectral analyser ( 105 ) operable in the invisible wavelength spectrum to analyse radiation which has been varied by the matter and is in the invisible wavelength spectrum. The system may further include a colour camera ( 102 ) and an arrangement which applies camera image interpretation to radiation which has been varied by the matter. The analysing arrangement ( 106 ) controls the operation of air valves for compressed air nozzles ( 109 ) so as to eject wanted or unwanted matter from the advancing device ( 101 ).
