The invention discloses a grain image splicing method and device and electronic equipment. The method comprises the following steps: acquiring each to-be-spliced sub-image of a crystal grain image; determining the distribution condition of each to-be-spliced sub-image, and determining an initial anchor area according to the distribution condition; acquiring a peripheral closed-loop image of each layer, wherein the peripheral closed-loop image of each layer is obtained by splicing to-be-spliced sub-images which are sequentially distributed from inside to outside in a radiation manner by taking the initial anchor area as a center; and splicing the initial anchor region and the peripheral closed-loop image of each layer to form a target crystal grain image, splicing and fusing the initial anchor region and the adjacent peripheral closed-loop image, and then splicing and fusing the initial anchor region and the adjacent peripheral closed-loop image until the initial anchor region and the peripheral closed-loop im
