Problems solved by technology

However, there are many deficiencies in the current palm vein recognition. For example, the collected image information is not clear and accurate, and there is a lot of redundant information in the extracted image information. These problems interfere with the matching of palm vein features and affect the recognition results of palm vein features.

[0112] see Figure 8 , Figure 8 It is a functional block diagram of the palm vein identification and matching device 100 . The device includes: a collection module 110 , a preprocessing module 120 , an extraction module 130 and a matching module 140 .

[0113] The acquisition module 110 is configured to acquire palm vein images.

[0114] The preprocessing module 120 is configured to perform image preprocessing on the palm vein image to obtain a region of interest 150 to be identified.

[0115] Specifically, the implementation of the preprocessing module 120 includes:

[0116] Processing the palm vein image to obtain a corresponding binarized image;

[0117] Perform edge detection on the binarized image to obtain the outline of the palm 600 in the palm vein image;

[0118] obtaining the position of the root point based on the profile;

[0119] The region of interest 150 to be identified is obtained according to the position of the root point.

Abstract

The invention provides a method and a device for recognizing and matching a palm vein. A palm vein image is acquired, image pretreatment is carried out on the palm vein image, and a to-be-recognized region of interest is acquired. Based on the region of interest, palm vein features are extracted, the extracted palm vein features are matched with pre-stored palm vein features in a database, and when matching is realized, preset operation is executed. Thus, distinct and accurate palm vein image information can be obtained, and interference with palm vein feature matching and bad influences on palm vein feature recognition are reduced.

Description

technical field [0001] The invention relates to the field of biological information identification, in particular to a palm vein identification and matching method and device. Background technique [0002] Biometric features are inherent, with the characteristics of stability, uniqueness, and convenience. Therefore, biometric technology is used as a means of identity verification to gradually replace traditional identification methods such as keys and passwords. Biometric technology refers to the technology of using some biological characteristics of the human body, such as face, iris, fingerprint, palm vein, hand shape, etc. for identification. It mainly includes: collecting images, extracting biometric information from the collected images, and then The extracted feature information is matched with all or part of the pre-registered feature information in the database, and the authenticated person is authenticated according to the matching result. [0003] Palm vein recogn...
