Embodiment

[0041] The present invention relates to an identification method combining palm veins and finger contours, comprising the following steps:

[0042] 1. Palm vein and finger contour image acquisition. The palm vein and finger outline image acquisition device is mainly composed of the acquisition device box, a near-infrared light source composed of an LED array with a wavelength of 850nm, a camera, a uniform light plate, an infrared filter, and an internal reflective material. The near-infrared light reflected by the palm is imaged on the camera. There are light-absorbing materials on the inner wall of the palm vein collection box to prevent light reflection on the inner wall of the box. The LED light source is perpendicular to the background. Collectors only need to place their palms upward and flat into the entrance of the collection device, and naturally stretch out four fingers to conveniently collect images of palm veins and finger contours.

[0043] 2. Extract the length...

Abstract

The invention discloses a method for using human body palm biology information to identify identities, and relates to an identity identification method. The method for using the human body palm biology information to identify the identities includes following steps: a, collecting images of palm veins and finger outlines: collecting the images of the palm veins and the finger outlines through photographing once under 850nm near infrared light; b, extracting the lengths and the widths of a little finger, an index finger, a middle finger and a ring finger from the images, calculating relative information between the length and the width of each finger, and using the relative information as four finger outline feature information; c, positioning an area which the palm veins are interesting in, and extracting palm vein information so as to form palm vein feature information; d, identifying matching. The method for using the human body palm biology information to identify the identities solves the problem that identification accuracy is influenced due to the fact that the palm veins of a small quantity of crowds are poor in definition by adding finger outline features convenient to obtain, and furthermore meets requirements for single biology feature identification accuracy by using the palm vein information in a human body, which is high in security and high in user acceptance level, to identify the personal identities.

Description

technical field [0001] The invention relates to an identity identification method, in particular to an identity identification method using human palm biometric information. Background technique [0002] The identification technology of human biometrics refers to the technology of identifying personal identity by using the inherent physical characteristics of the human body such as face and fingerprints, or behavioral characteristics such as voice and gait. Compared with the traditional methods based on passwords or identification cards, it has better effectiveness, security and reliability, and has increasingly gained a broader application market. Currently commonly used face recognition and fingerprint recognition, because the face is easy to be stolen and photographed, and the fingerprint is easy to be left on the hand-held object to be stolen. Both of them have security loopholes, which affect security, and are not suitable for high-level security requirements. occa...
