Sedimentary facies boundary extraction method and device, electronic equipment and storage medium

The invention discloses a sedimentary facies boundary extraction method and device, electronic equipment and a storage medium. The method comprises the following steps: acquiring a starting pixel point and an ending pixel point of a region of interest in a seismic facies image; calculating an adjacent boundary cost value between the starting pixel point and the ending pixel point based on a predetermined joint cost function to obtain at least one target boundary cost value; wherein the adjacent boundary cost value is determined based on a gradient direction characteristic value of the pixel point, a Laplace characteristic value of a neighborhood pixel point adjacent to the pixel point and a gradient intensity characteristic value; and determining the sedimentary facies boundary in the seismic facies image according to the at least one target boundary cost value. According to the technical scheme, the sedimentary facies boundary can be extracted, and the problem of inaccurate boundary extraction caused by larg
