A method for recording and processing digital images of a slabbed drill core (10), is characterised in that the images of the drill core (10) are recorded directly by means of a high resolution, digital camera (9) moved in equal intervals along the drill core (10). While the records are taken, the drill core is illuminated by a constant light in a direction having an angle (.alpha.) with respect to the surface of the drill core, as the digital recorded data are transferred to a computer (6) for further processing and storing.
L'invention concerne un procédé d'enregistrement et de traitement d'images numériques d'une carotte de forage (10), découpée en tranches. Ledit procédé est caractérisé en ce que les images de la carotte de forage (10) sont enregistrées directement au moyen d'une caméra numérique (9) à haute résolution, déplacée à intervalles égaux le long de la carotte de forage (10). Pendant l'enregistrement, la carotte de forage est éclairée par une lumière constante selon un angle (.alpha.) par rapport à la surface de la carotte de forage, tandis que les données numériques enregistrées sont transférées à un ordinateur (6) pour traitement ultérieur et stockage.
