Description

一种使用掌静脉识别的门禁控制系统 技术领域
本发明涉及一种使用掌静脉识别的门禁控制系统，属于第三代生物识别技术领域。
背景技术
门禁管理系统可以控制人员的出入，还可以控制人员在楼内及敏感区域的行为并准确记录和统计管理数据的数字化出入控制系统。它主要解决了企事业单位、学校、社区、办公室等重要场所的安全问题。在楼门口、电梯等处安装控制装置，例如门禁控制器、密码键盘等。住户要想进入，必须有卡或输入正确的密码，或按专用生物密码才能获准通过。门禁管理系统可有效管理门的开启与关闭，保证授权人员自由出入，限制未授权人员进入。
门禁及安防系统是用来保护人员和财产安全的，因此系统自身必须安全。这里所说的高安全性，一方面是指产品或系统的自然属性或准自然属性，应该保证设备、系统运行的安全和操作者的安全，例如：设备和系统本身要能防高温、低温、温热、烟雾、霉菌、雨淋，并能防辐射、防电磁干扰(电磁兼容性)、防冲击、防碰撞、防跌落等，设备和系统的运行安全还包括防火、防雷击、防爆、防触电等；另一方面，门禁及安防系统还应具有防人为破坏的功能，如：具有防破坏的保护壳体，以及具有防拆报警、防短路和开等。
现有技术中，大多数采用的是卡式管理，比较先进的采用的是生物技术进行验证管理，而掌静脉识别生物技术在这个领域刚刚发展。用掌静脉进行身份认证时，获取的是掌静脉的图像特征，是指活体时才存在的特征。在该系统中，非活体的手掌是得不到静脉图像特征的，因而无法识别，从而也就无法造假。用掌静脉进行身份认证时，获取的是手掌内部的静脉图像特征，而不是手掌表面的图像特征。因此，不存在任何由于手掌表面的损伤、磨损、干燥或太湿等带来的识别障碍。用掌静脉进行身份认证，获取手掌静脉图像时，手掌无须与设备接触，轻轻一放，即可完成识别。这种方式没有手接触设备时的不卫生的问题以及手掌表面特征可能被复制所带来的安全问题，并避免了被当作审查对象的心理不适，同时也不会因脏物污染后无法识别。手掌静脉方式由于静脉位于手掌内部，气温等外部因素的影响程度可以忽略不计，几乎适用于所有用户。用户接受度好。除了无需与扫描器表面发生直接接触以外，这种非侵入性的扫描过程既简单又自然，减轻了用户由于担心卫生程度或使用麻烦而可能存在的抗拒心理。因为有了前面的活体识别、内部特征和非接触式3个方面的特征，确保了使用者的掌静脉特征很难被伪造。所以掌静脉识别系统安全等级高，特别适合于安全要求高的场所使用。但是现有技术中还存在以下问题待解决：(1)属于内生理特征，不会磨损，较难伪造，具有很高安全性。(2)血管特征通常更明显，容易辨识，抗干扰性好。(3) 可实现非接触式测量，卫生性好，易于为用户接受。(4)不易受手表面伤痕或油污的影响。以上技术存在的缺点是：采集设备有特殊要求，设计相对复杂，制造成本高。
发明内容

第一步、训练及投影掌静脉图像，通过分类器的匹配得到五个候选的掌静脉图像，训练得到的最佳图像特征；
第二步、分类器中的五个候选掌静脉图像中找到最佳测试图像；
第三步、由匹配关键点数目来确定验证准则，设定匹配点数目最大的掌静脉描述符是最有可能的项，通过特征匹配，得到目标掌静脉图像。

优选的，所述音频电路主要包括音频的输入和输出处理电路。由于音频输出信号是电压为十几毫伏的模拟信号，因而需先通过功放电路进行增益调节，并将A/D转换电路转换后的数字音频信号传送到控制芯片。
优选的，cortex A8以上ARM处理器的电压通过电源适配器变压获得5V，并将5V电压通过低压差电压调节器AS1117AR-3.3V分压获取,并通过电容将其电压进行稳压处理,从而保证为各元器件和接口提供稳定的3.3V电压以及为摄像头模块提供1.8V和2.5V电压。

具体实施方式：
考勤系统通过掌静脉考勤系统，录入掌静脉。在掌静脉采集单元3异常时，CPU将切换为掌静脉录入系统，通过这两种考勤系统交替运行并且均与图像考勤系统结合，在通过掌静脉后，同时CPU调出资源数据池中的图像与之对比，图像相似度达到预设值后才录入考勤信息，考勤多元化、有效化、准确化。
本发明中的考勤系统还通过掌静脉采集单元，安装、使用时都可以根据实际情况灵活选择考勤系统的录入方式，而所述掌静脉采集单元正常运行时，能够通过语音播报单元发出提示，方便被考勤人员使用。
以上所述仅是本发明的优选实施方式，本发明的保护范围并不仅局限于上述实施例，凡属于本发明思路下的技术方案均属于本发明的保护范围。应当指出，对于本技术领域的普通技术人员来说，在不脱离本发明原理前提下的若干改进和润饰，这些改进和润饰也应视为本发明的保护范围。
