发明名称 Method and device for dual lens fingerprint identification
摘要 A dual lens fingerprint identification method comprises following steps. A first fingerprint image and a second fingerprint image of a finger in contact with a touch panel are captured by a first lens and a second lens respectively. The first fingerprint image and the second fingerprint image are partially overlapped with each other. An image processing procedure is performed to merge the first fingerprint image and the second fingerprint image into a third fingerprint image, and a calculation procedure is performed to compare a plurality of fingerprint characteristic points captured from the third fingerprint image with a plurality of preset characteristic points captured from a preset fingerprint image.

主权项 1. A dual lens fingerprint identification method, comprising steps of: using a first lens to capture a first fingerprint image of a finger in contact with a touch panel and using a second lens to capture a second fingerprint image of the finger in contact with the touch panel, wherein the first fingerprint image and the second fingerprint image are partially overlapped with each other; and performing an image processing procedure to merge the first fingerprint image and the second fingerprint image into a third fingerprint image, and performing a calculation procedure to compare a plurality of fingerprint characteristic points captured from the third fingerprint image with a plurality of preset characteristic points captured from a preset fingerprint image, wherein the first lens comprises a first angle formed between a first optical axis of the first lens and a surface of the touch panel, and the second lens comprises a second angle formed between a second optical axis of the second lens and the surface, wherein at least one of the first angle and the second angle is between 40 degrees and 85 degrees.
