摘要
介绍了将手形、掌纹和手掌静脉身份识别理论与FPGA和DSP数字处理系统相结合构成能够方便用于门禁、考勤等的具有高可靠性和高安全性要求的快速身份识别装置。装置采用可见光和近红外双摄像头提高对手形、掌纹和手掌静脉图像的有效获取。利用FPGA实现双摄像头图像数据的同步采集、数据缓存以及对液晶显示屏、补光系统等的控制,以减少DSP的负担,使DSP能够专注于对手形、掌纹和手掌静脉的数据处理识别工作,保证系统运行的实时性。
The paper introduced eombinating the hand shape, palm prints and hand vein identification theory, FPGA and DSP digital processing system to make the rapid identification device, with high reliability and safety, used for access control and atten- dance and so on. Through visible and near infrared camera to effectively acquire hand shape, palm prints and palm vein image. Using FPGA to absolute synchronously acquire dual camera image data, achieve data cache, and control the liquid crystal display screen and lighting system, in order to reduce the burden of DSP, so that DSP can focus on the opponent shape, palm prints and palm vein data processing and recognition work, to ensure the system run time.
