摘　　要：为研究非接触式采集模式下的在线掌纹识别技术,利用Matlab提供的图像采集工具箱及GUI功能设计并实现了一套非接触式在线掌纹识别模拟系统;在Matlab环境下,设计的系统可模拟真实的非接触式在线掌纹识别过程,实现掌纹图像采集、预处理、特征提取及特征匹配等功能模块,在线实验多种掌纹特征提取方法的正确识别率及运行时间,为非接触式在线掌纹识别技术的深入研究和产品开发提供实验数据和理论依据。To study on--line palmprint identification technology under non--contact mode, a set of simulated system of non--contact on --line palmprint identification using of functions of Image Acquisition Toolbox and GUI are provided by Matiab software is designed and realized in this paper. The system simulated real process of non--contact on--line palmprint identification and achieved some functional modules, which are palmprint collection, preprocessing, featrue extraction, and feature matching, and experimented a variety of methods of feature extraction on--line for texting their correct rate and running time. The research of simulated system in this paper provides experimental datas and theoretical basis for making in--depth research and developmenting product of non--contact on--line palmprint recognition technology.
