摘要
提出了一种基于DSP的指纹采集系统,主要介绍了系统的组成原理、硬软件电路设计与实现。该系统以DSP芯片TMS320VC5402为核心,以FPS200为指纹传感器,通过USB接口实现与主机之间的通信,实现了一种高效低耗的嵌入式指纹采集系统。实验结果表明,该系统采集速度快、采集图像清晰且指纹图像预处理效果良好。
A kind of fingerprint acquisition system is presented based on DSP, in which composing, design and realization of hardware and software are introduced. The kernel of this system is DSP TMS320VC5402, and the sensor is FPS200. By communicating with the host by USB, an embedded fingerprint acquisition system is realized with high - effect and low - dissipation. The result of experiments indicates that the system works with great fingerprint acquisition efficiency, high definition images and good preprocessing effect.
