摘要
采用指纹信息作为身份识别手段的应用已经很广泛,但传统的指纹信息识别身份时存在容易被仿造的缺点。3D指纹信息不但可以进一步提高指纹识别率而且可以很好地克服该缺点。在此主要介绍利用双目视角技术采集3D指纹信息,提出了一种3D指纹信息采集的解决方案。详细介绍了以MTK平台作为控制平台,DSP芯片做算法处理的硬件设计。该设计的硬件成本低且安全性高。在C/S结构的系统设计中,通过测试该硬件方案可以直接在客户端上采集信息,便携性好。
To take the fingerprint information as a means of identity recognition is very popular now, but the traditional means has a fault being easy to be copied. 3-D fingerprint information can further improve the recognition rate and overcome this fault. The 3-D fingerprint information acquisition realized by the aid of the binocular vision technology is introduced. A solution scheme to correct 3-D fingerprint information is proposed. The hardware design of using MTK as a control platform and DSP chip for algorithm processing is described. The testing results show that the system can directly correct information on the client- side. The system has low cost, high securety, high accuracy and good portability.
