Abstract
An unlocking method and an intelligent lock based on vein input and identification. The method includes steps of obtaining positional information of a target part, adjusting a position of the target part to be within a preset position-identification range, inputting a vein image of the target part to be within the position-identification range, where the vein image includes a first vein image and a second vein image; processing the input first vein image to obtain a first vein feature of the first vein image, constructing a feature map based on the first vein feature; processing the input second vein image to obtain a second vein feature of the second vein image, comparing the second vein feature with the first vein feature of the feature map to obtain a comparison result, and determining an unlocking state based on the comparison result.
