摘要
现有的户籍管理系统大多不能实现指纹图像的无线采集,人员进行指纹采集需在指定地点完成,极大限制了采集效率,需要用户走到户籍管理中心进行指纹采集,对于距离户籍管理中心较远的用户来说,这种传统的采集方式极为方便。为了让用户在家中就能使用指纹采集系统,提出了利用无线传输对户籍管理中心的采集设备进行数据传输,从而改变只能由用户走到户籍管理中心进行指纹采集的传统方式。目前的Canny边界算子提取出的边界往往含有大量噪声,与指纹真实的边界存在巨大差别,于是针对这些问题进行了以下设计:实现基于DSP的指纹采集系统设计,采用无线传输的方式上传数据;通过优化Canny边界提取算子更好地对边界进行提取。这样能够设计出一个识别速度更快的指纹无线采集系统,并实现了对Canny算子的优化处理。
Most existing household registration management systems don’t have the function of wireless fingerprint acquisition,The process of fingerprint acquisition is completed in a designated place,which greatly limits the efficiency of the acquisition,this traditional way is very inconvenient for users lived far away from household registration management center,In order to allow users to use fingerprint acquisition system at home,take advantage of wireless transmission to transmit the data in household registration management centers’acquisition devices,and this can change the traditional type of users must go to household registration management center to make their fingerprints collected.Boundary extraction after existing Canny algorithm includes a lot of noise,it has a big difference between true boundary of fingerprint,to solve those questions the following design is given:a)Realize the design of fingerprint acquisition system based on DSP,and upload data by wireless transmission.b)By optimizing Canny algorithm,better boundary extraction effect is got.By these designs,a fingerprint wireless acquisition system which has a faster acquisition time is achieved,and optimization of Canny algorithm is achieved too.
