摘要： The present disclosure provides a non-contact three-dimensional palm vein modeling method, including: shooting palm images of M different positions, where a quantity of shot palm images of each different position is one or more, the different positions are positions of a palm relative to an image shooting apparatus; picking out a picked palm image satisfying a preset condition from the shot palm images, where a quantity of picked palm images of each position is one or more, and the quantity of picked palm images of each position is less than or equal to a quantity of shot palm images of the corresponding position; extracting palm vein feature data from the picked palm images; performing feature fusion on the palm vein feature data extracted from the picked palm images to form one first feature template; and forming a user feature template based on the one first feature template.
