Exploring Implementation of Three-dimensional Skeleton Reconstruction of Finger Vein for PPS

摘要

The heart of the product service system is combining the product and service organically, and then achieving a certain function to meet the needs of consumers. Products and services of identification based on finger veins are important parts of the development of cloud computing and Internet of Things. At present, the products using finger vein recognition are mostly applied or used in a small scale. Because different finger veins may have same or similar 2D projections which probably lead to recognition errors. Considering the request of the user and the need of information safety construction of enterprises, this paper proposes a three-dimensional skeleton reconstruction method of finger vein based on a quadrature biplane image acquisition system. By using the topological characteristics of finger vein skeletons, the matching for feature points of two 2D finger-vein skeletons has been achieved. Finally, piecewise curve fitting based on 2D skeleton segments from two 2D projections is developed to reconstruct the complete 3D skeleton. In the industrial of the IoT, this technology can be carried in various terminal products of the PSS, which can maximize the value for consumers and expedite PSS for development.
