摘要
本文介绍了一种基于结构光的非接触式三维掌纹采集系统。该系统在采集数据时,使用了结构光原理以获取3D点云数据,在摄像机和投影仪之间通过执行三角测量来生成手掌的表面信息。三维掌纹采集系统的设备组件主要由DLP4500型数字结构光投影仪、设备固定支撑结构和Imperx:C5180相机组成,能够获取高精度、高质量的三维掌纹数据。
This article introduces a non-contact three-dimensional palmprint acquisition system based on structured light.When the system collects data,it uses the structured light principle to obtain 3D point cloud data,and recovers the surface information of the palm by performing triangulation between the camera and the projector.This design builds a 3D palmprint acquisition system with DLP4500 digital structured light projection,equipment fixed support structure and Imperx:C5180 camera as the main equipment components to obtain high-precision,high-quality 3D palmprint data.
