Title (EN) A COMPUTER-IMPLEMENTED METHOD AND A SYSTEM FOR CREATING A THREE-DIMENSIONAL MINERAL MODEL OF A SAMPLE OF A HETEROGENEROUS MEDIUM

Abstract:
(EN) An initial 3D microstructural image of at least a part of a sample consisting of at least one mineral is obtained. Then, a mineral distribution image of at least one part of the sample is obtained so that each obtained mineral distribution image at least partially overlaps with the obtained initial 3D microstructural image and spatial registration with the obtained initial 3D microstructural image is provided in overlapping regions. Then at least one local feature in each point of the obtained initial 3D microstructural image is extracted by a computing system. A correspondence is found between the extracted local features in each point of the overlapping regions in the obtained initial 3D microstructural image and the minerals in the corresponding points in the overlapping regions in the obtained mineral distribution images. The extracted local features in each point of the obtained initial 3D microstructural image and the found correspondence are used for segmenting the obtained initial 3D microstructural image. A 3D mineral model of the sample is created from the segmented initial 3D microstructural image.
(FR) Une image microstructurale 3D initiale d'au moins une partie d'un échantillon constitué d'au moins un minéral est obtenue. Ensuite, une image de répartition minérale d'au moins une partie de l'échantillon est obtenue de telle façon que chaque image de répartition minérale obtenue se chevauche au moins partiellement avec l'image microstructurale 3D initiale obtenue et qu'un alignement spatial avec l'image microstructurale 3D initiale obtenue soit assuré dans les régions de chevauchement. Ensuite, au moins une caractéristique locale en chaque point de l'image microstructurale 3D initiale obtenue est extraite par un système informatique. Une correspondance est trouvée entre les caractéristiques locales extraites en chaque point des régions de chevauchement dans l'image microstructurale 3D initiale obtenue et les minéraux présents aux points correspondants des régions de chevauchement dans les images obtenues de répartition minérale. Les caractéristiques locales extraites en chaque point de l'image microstructurale 3D initiale obtenue et la correspondance trouvée sont utilisées pour segmenter l'image microstructurale 3D initiale obtenue. Un modèle minéral 3D de l'échantillon est créé à partir de l'image microstructurale 3D initiale segmentée.
