AI Technical Summary

Technical Problem

Existing non-contact palm recognition devices suffer from unstable imaging quality due to factors such as light source, palm distance, and posture, making it difficult to meet the needs of commercial applications. In particular, the accuracy of palm vein recognition is limited, and the image binarization processing methods in existing technologies have limited effectiveness.

Method used

A non-homogeneous binocular camera system is used to simultaneously capture different images of the palm using a first camera and a second camera. Deep learning methods are used to estimate the palm orientation and perform image correction. Palm print and palm vein information are processed separately to improve image quality and correction accuracy.

Benefits of technology

It improves image acquisition quality and correction accuracy, simplifies hardware equipment, supports multi-functional integration, and provides image processing with more dimensional data to meet the needs of commercial applications.

Abstract

The application discloses a non-homologous binocular camera with palm correction function, which is characterized by comprising a first camera for shooting a first image of a palm, a second camera for shooting a second image of the palm, wherein the first camera and the second camera are non-homologous cameras and are simultaneously shot, and a processor for detecting the palm on the first image and the second image, estimating a palm orientation, and correcting the first image and the second image according to the palm orientation. The non-homologous binocular system composed of the first camera and the second camera is used to directly process the first image and the second image, so that the quality of image acquisition is improved, and the palm orientation is used for correction, so that a palm with a larger angle can be processed, and the accuracy of correction is greatly improved.
