Palm print and palm vein identification method and palm print and palm vein image collection instrument

Abstract

The invention relates to a palm print and palm vein identification method. The method comprises: a batch of registered palm print and palm vein images are collected and used as biological features and corresponding information is recorded; a new palm print and palm vein image of a registered collected person is collected and is used as to-be-measured data; for the to-be-measured palm print and palm vein image, identification is carried out by three steps of palm print or palm vein area extraction, competition-coding-based feature extraction, and classification based on a combined expression classification frame; and reconstruction errors of palm print or palm vein image feature description operators of all registered collected people are calculated and a collected person with a minimum reconstruction error is selected and is used as a source of identity information of a to-be-identified palm print or palm vein image. In addition, a palm print and palm vein image collection instrument using the identification method is also provided. A camera, an illumination environment, and related function modules are arranged inside an enclosed dark room; interaction is carried out based on a convenient man-machine interface; and a non-contact collection space is arranged in front of a lens of the camera and thus the hand of the collected person can move freely in the collection space, so that the obtained collected image meets the identification requirement. Therefore, the identification rate is high; and the identification time is short.

Description

technical field [0001] The invention belongs to the technical field of computer identification, and relates to an identification technology aimed at human biological characteristics. Background technique [0002] With the rapid development of the Internet field, especially the e-commerce field, people have established more and more high-value personal accounts, and more and more attention has been paid to identity verification when logging in. Traditional passwords need to be memorized by users and manually input when using them, which is a very cumbersome process. Compared with traditional password or ID card authentication methods, the identification technology of human body biometrics can more effectively, safely and conveniently identify the identity of the registrant, and has broad development prospects. [0003] Among the biological characteristics of the human body, fingerprints, irises, handwriting, and human faces are commonly used at present. These characteristic...

Problems solved by technology

For example, in the system developed by Chen et al. (Chen et al.,Biometric verification by fusinghand geometry and palmprint,2007), each hardware part does not form a whole usable system, and data acquisition depends on manual operation, resulting in poor user experience

As another example, in the prototype system developed by Aykut and Ekinci (Aykut et al., Developing a contactless palmprint authentication system by introducing novel roi extraction method, 2015), because the equipment lacks the necessary mask, the LED light emitted by the light source is very easy to irradiate. In addition, the background of the collected palmprint image is uncertain, so the palmprint recognition algorithm is very complicated, which affects the recognition effect
