摘要
指纹自动连续采集系统是以DSP TMS320VC5402为核心,与MBF200型指纹传感器相结合,并通过USB接口与主机实现通信,采用VB将定时自动采集到的指纹在采集界面显示,然后选择效果最好的指纹,并存储到相应数据库中。该系统采集的指纹识别率高,具有很强的实用价值。
The automatic finger acquisition system takes DSP chip TMS320VC5402 as a core,and combines MBF200 as fingerprint sensor, and realizes the communication between DSP and the host through USB interface.The system realizes the fingerprint collected automatically and shown on collection interface with VB,then chooses the best fingerprint to save in the corresponding database.The rate of fingerprint identification of the system is high and the system design has a strong practical value.
