Title (EN) METHOD AND APPARATUS FOR GRADING SHELL EGGS
(FR) PROCEDE ET DISPOSITIF DE TRIAGE POUR LES ×UFS
Abstract:
(EN) In the grading of shell eggs passing in a stream through a candling bed, images of the eggs are compared with image data characteristic of eggs of known grade so as to assign a grade to each egg in the stream. Positional information representative of the movement of the eggs is combined with the assigned grade to control a mechanical egg routing device. Images of multiple egg streams may be multiplexed and processed together. The images may be Fourier transformed before comparison.
(FR) Dans le triage des ÷ufs défilant à travers un poste d'inspection, les images des ÷ufs sont comparées avec des données d'image caractéristiques des ÷ufs d'une classification connue afin de donner une classification à chaque ÷uf inspecté. Des informations de position représentatives du mouvement des ÷ufs sont combinées avec la classification donnée pour commander un système mécanique d'acheminement des ÷ufs. Les images du défilement multiple des ÷ufs peuvent être multiplexées et traitées ensemble. Les images peuvent subir une transformation de Fourier avant comparaison.
