Title:
METHOD FOR PERFORMING THREE-DIMENSIONAL MODELING BY SCANNING PALM VEINS AND RECOGNITION METHOD
Document Type and Number:
WIPO Patent Application WO/2021/128433
Kind Code:
A1
Abstract:
The present application relates to the technical field of palm vein recognition, and provides a method for performing three-dimensional modeling by scanning palm veins and a recognition method. The three-dimensional modeling method obtains a blood vessel vein stereogram under a three-dimensional coordinate system by performing stereoscopic scanning on palm vein blood vessel lines of a user, then preprocesses the blood vessel vein stereogram, removes other veins except the trunk and the first-stage torso extending from the trunk in the blood vessel veins, so as to obtain a standard palm vein stereoscopic model and a standard palm vein stereoscopic model database, and the acquisition and three-dimensional modeling process of the palm vein of the user is completed. The three-dimensional recognition method performs recognition through the first-stage comparison and second-stage comparison in the standard palm vein stereoscopic model database for the current palm vein stereoscopic model. The three-dimensional modeling and recognition methods realize the three-dimensional modeling and recognition of the palm vein for the user, the correct recognition can be performed no matter how the posture of the hand of the user changes.
