摘要
刮擦式指纹传感器具有体积小、功耗低的优点,适合于构建嵌入式自动指纹识别系统。介绍了一种基于WindowsCE操作系统和AES2510刮擦式指纹传感器的嵌入式自动指纹识别系统,着重阐述了基于流接口驱动模型的指纹传感器驱动程序的实现,以及基于像素灰度级变化统计信息的滑动指纹序列拼接算法。测试结果表明,系统运行效率高,占用处理器资源小。
Swipe fingerprint sensor is suitable for embedded automatic fingerprint identification systems because of small bulk and low power-resumption. The design of an embedded fingerprint identification system based on Windows CE operating system and AES2510 swipe sensor is presented. The implementation of the driver for the swipe sensor based on stream interface model, as well as an algorithm for mosaic of swipe fingerprint sequences based on statistics information of variety in gray scale ofpixels, is explained in detail. The test shows that this system is efficient and occupies a small percentage of processor resource.
