Problems solved by technology

[0002] Most of the existing optical fingerprint collection adopts a prism structure. Since the fingerprint collection surface is not perpendicular to the imaging optical axis, the fingerprint image is compressed in the oblique direction, and the fingerprint image definition is not high.

Abstract

The invention discloses a fingerprint collection assembly and device, the fingerprint collection assembly comprises a plurality of subunits with triangular sections, the adjacent subunits are connected with each other, and the subunits are arranged in a linear or circumferential array. The fingerprint collection assembly is applied to the fingerprint collection device. In use, an illumination light source is arranged above the fingerprint collection assembly; an image sensor is arranged below the fingerprint collection assembly; when a finger is in contact with the fingerprint collection assembly; the ridge line of the fingerprint is in contact with the inclined plane of the subunit, the valley line of the fingerprint is separated from the subunit, light penetrating through the ridge linecan enter the image sensor after being refracted, and light penetrating through the valley line cannot enter the image sensor, so that a fingerprint image with bright ridge line and dark valley line can be formed, and the definition of the fingerprint can be improved.

Description

technical field [0001] The invention relates to the technical field of biological identification, in particular to a fingerprint collection component and device. Background technique [0002] Most of the existing optical fingerprint collection adopts a prism structure. Since the fingerprint collection surface is not perpendicular to the imaging optical axis, the fingerprint image is compressed in the oblique direction, and the fingerprint image definition is not high. Contents of the invention [0003] The present invention aims to solve at least one of the technical problems existing in the prior art. For this reason, the present invention proposes a fingerprint collection component, which can improve the definition of fingerprint images. [0004] The present invention also proposes a fingerprint collection device having the above-mentioned fingerprint collection group. [0005] The fingerprint collection assembly according to the embodiment of the first aspect of the p...
