La présente invention concerne un système de photographie optique automatique d'une carotte prélevée par perçage à colonne dans la mer ainsi qu'un procédé de photographie correspondant et, plus précisément, un système de photographie optique automatique d'une carotte prélevée par perçage à colonne dans la mer ainsi qu'un procédé de photographie correspondant. Le système est apte à : acquérir une image précise en découpant une carotte (prélevée par perçage à colonne) d'une longueur d'au moins 1m et pouvant atteindre des douzaines de m, en longueurs prédéterminées ; placer le morceau découpé sur un plateau d'échantillon comportant une partie de mesurage de longueur ; photographier l'échantillon par sections, sans déformation, à l'aide d'une caméra qui se déplace automatiquement dans la direction des axes x, y et z, au moyen d'une partie de commande ; et composer les images photographiées par sections dans une position précise, sans erreur, d'après la mesure indiquée par la partie de mesurage de longueur.
