The invention discloses a hand back vein recognition method based on rotation transformation and a related device, and relates to the technical field of hand back vein recognition, and the method comprises the following steps: constructing an evaluation image pair, carrying out the model evaluation through a trained vein recognition model, obtaining a mean value threshold value, a standard deviation threshold value, an optimal distance index and an optimal distance threshold value, and carrying out the recognition of a hand back vein. Then obtaining a to-be-recognized hand back image, performing similarity distance calculation on the to-be-recognized hand back vein image and all images in the reference image library to obtain a reference image corresponding to a distance minimum value, and taking the reference image as a candidate image; rotating the to-be-recognized image, calculating a similarity distance with the candidate image, and sorting the to-be-recognized image; and obtaining an optimal distance bas
