Zusammenfassung:The embodiment of the invention discloses a core micro-crack extraction method and device, electronic equipment and a storage medium. The method comprises the following steps: acquiring a two-dimensional scanning image of a core; the two-dimensional scanning image is preprocessed, a two-dimensional micro-crack image is obtained, and the two-dimensional micro-crack image contains a two-dimensional micro-crack area; extracting a two-dimensional filled microcrack and a two-dimensional unfilled microcrack from the two-dimensional microcrack region to obtain a two-dimensional classification image; and three-dimensional reconstruction of the rock core is carried out on the two-dimensional classification image to obtain a three-dimensional image corresponding to the rock core, and the three-dimensional image comprises a plurality of filled microcracks and a plurality of unfilled microcracks. According to the technical scheme provided by the embodiment of the invention, the filled microfractures and the unfilled micr
