Embodiment Construction

[0033] It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and examples.

[0034] refer to figure 1 , the present invention provides a method for intercommunication recognition of finger vein images for images collected by different finger vein devices, the method comprising the following steps:

[0035] Step S100, calculating and analyzing the finger vein images collected by different finger vein devices to obtain the proportional relationship between the images corresponding to the images of different finger vein devices;

[0036] Step S200, according to the proportional relationship, corresponding scaling transformation is performed on the finger vein images collected by different finger vein devices;

[0037] Step S300, correcting the scaled and transformed imag...

Abstract

The invention discloses a finger vein image intercommunication identification method and device and a storage medium. The method includes the following steps: conducting calculation and analysis on finger vein images collected by different finger vein devices and obtaining a constant proportion relation of images to images among the different finger vein devices; according to the constant proportion relation, conducting corresponding zoom transformation on the finger vein images collected by the different finger vein devices; and correcting the images that have undergone zoom transformation according to dimensional of original images. The corresponding constant proportion relation is found at first, then corresponding zoom transformation is carried out on the images according to the constant proportion relation, the images that have undergone zoom transformation are corrected, and finally the obtained images can be used for identification of the different finger vein devices. The calculation complexity is low, intercommunication identification among different types of finger vein images is realized while an identification rate is not affected, convenience is brought to intercommunication and application among different products, and risks caused by device upgrading are reduced.

Description

technical field [0001] The present invention relates to the field of biometric identification, in particular, to a method, device and storage medium for mutual recognition of finger vein images. Background technique [0002] With the progress of society and the development of the times, finger vein biometric recognition technology has gradually emerged in people's daily life. It uses the unique physiological or behavioral characteristics of the human body to automatically identify personal identities. It has the advantages of no need to remember passwords, high uniqueness, and difficulty in being stolen. At the same time, it is simple, convenient and quick to operate. Therefore, it has been extensively studied in recent years and has developed rapidly. . Finger vein recognition technology is a hot topic widely studied at present. Finger vein recognition technology is also called subcutaneous blood vessel recognition technology. Finger vein recognition is an important biolog...
