Abstract

The invention discloses a non-contact finger and palm print acquisition device and method. The device comprises a first shooting mechanism, a second shooting mechanism and a shell, wherein the first shooting mechanism and the second shooting mechanism are installed on a supporting structure in the shell, and a finger placing area and a palm placing area are arranged outside the shell; wherein thefirst shooting mechanism comprises a rotating device, a line-scan digital camera mounted on the rotating device and a first lighting light column with a preset angle; the second shooting mechanism comprises a moving device, an area-array camera installed on the moving device and a second illumination light column with a preset angle. A linear array camera rotates around a fingerprint surface to scan and shoot a fingerprint in an omnibearing manner, and a high-quality and large-area 2D fingerprint image of a finger fingerprint surface is directly obtained; a main palmprint and a side palmprintare shot through the movable area-array camera, and images of the main palmprint and the side palmprint are obtained through one-time shooting without moving the palm; two shooting mechanisms are integrated through the shell, so that the comprehensive collection performance of the finger and palm prints is improved.

Description

technical field [0001] The invention belongs to the field of finger and palm print collection, and relates to a non-contact finger and palm print collection device and method. Background technique [0002] Most traditional fingerprint image capture systems used in public security systems, security, customs, and immigration rely on physical contact between fingers and palms and fingerprint capture devices. When high-quality, complete, and large-area fingerprints are required, fingers and palms need to be pressed against the fingerprint collection device and rolled from side to side to increase the total contact area. When such devices are used by unskilled and submissive subjects, the additional force used to capture often results in large deformation and distortion of fingerprints and palm prints, and the subject may move intentionally or unconsciously during the capture process Fingers or palms cause blurring of the captured finger and palm print images, resulting in failu...
