Description

影像采集验证平台 技术领域
本实用新型涉及图像处理领域，更具体地说，涉及一种影像采集验证平台。
背景技术
随着金融行业的业务扩展，以银行为代表的金融行业的影像化要求从硬件和部署上呈两端式发展：一方面要求低端设备的网点部署和分散采集；另一方面区域中心建立，中大型设备的需求呈稳定增长。同时，票据处理从原来的微缩存档查询向业务过程影像处理转变，对影像处理系统的各项功能及省级行规模的部署也提出了更高更明确的要求。
以银行为代表的金融行业的对公业务中，对于各种规格的身份证件、客户资料、业务凭证、银行卡、现金、客户影像和立体物品等物件的现场采集和验印，多采用各种验印设备，但现有设备在使用过程中普遍存在诸多弊端，如电源板不稳定、采集的图像质量不能充分满足银行信息管理的需求、对图片的处理过程复杂耗时、采集的时候无法同时采集正反面的影像等。另一方面，在柜员通过验印设备完成现场采集和验印工作后，进行下一步的业务操作时，若遇到授权任务，通常要通知授权主管前来授权。授权主管主要核实三个方面的内容：一、柜员之前在核心系统上所做的操作是否有误；二、该笔业务是否实时发生、客户是否在现场；三、客户提交的凭证和客户本身身份是否正确关联。核实完毕后，由授权主管决定是否进行授权，授权一般使用磁卡或IC卡等传统的授权模式。这种传统授权模式的弊端在于：只纪录了授权结果，而未对授权行为进行系统的管理和控制；人力资源的浪费和不合理化，既增加了成本，又不利于网点的规模性扩大；不能满足以银行为代表的金融行业的数据大集中模式下的风险控制和效率问题，无法适应金融体制改革下对银行未来发展趋势的需求和挑战。

当需要采集文件、证件等的背面影像时，照明光源82开启，通过平面镜83的反射照亮物体背面，背面影像通过观察窗101，由平面镜83反射，并由第四摄像头81采集。
在折射模块8采集背面影像时，采集平台能够同时对于采集对象的正面影像采集，因此无需手动对采集对象进行翻转处理，提高了业务办理的效率。
图4为本实用新型的折射模块实施例二结构示意图，折射模块8包括等腰三角形棱镜84（反射棱镜）、第四摄像头81和照明光源82，等腰三角形棱镜84设置在底座1的观察窗101正下方且棱镜斜边侧面与第四摄像头81轴线成45°±15°夹角。
与折射模块的实施例一相比，采用反射棱镜代替平面镜，一般的，反射棱镜比平面镜的光损耗低，因此获得的背面影像质量更高。
图5为本实用新型的折射模块实施例三的结构示意图，折射模块8包括成像透镜85以及第四摄像头81、照明光源82，第四摄像头81设置于观察窗101正下方，且轴线垂直于观察窗101平面，成像透镜85设置于观察窗101与第四摄像头81之间且与第四摄像头81共轴。
优选的，成像透镜85装配在可调节的支架上，通过调节支架可改变成像透镜85与第四摄像头81间的距离，从而调整成像的质量。
图6为本实用新型的折射模块实施例四的结构示意图，为图3、图4实施例的一种改进方式。图3、图4实施例中，采用平面镜或等腰三角形棱镜进行反射时，由于平面镜或等腰三角形棱镜的位移使得从平面镜或等腰三角形棱镜的反射光不能到达第四摄像头81，或者到达的成像出现拉伸形变，为了克服这个问题，图5的实施例引入第一成像透镜86和第二成像透镜87.
在平面镜83或等腰三角形棱镜84与第四摄像头81之间设置第一成像透镜86和第二成像透镜87，所述第一成像透镜86和第二成像透镜87与第四摄像头81共轴，第四摄像头81位于第一成像透镜86的前焦点，平面镜或等腰三角形棱镜位于第二成像透镜87的后交点，第一成像透镜86的后焦点与第二成像透镜87的前交点重合。即：第四摄像头81、第一成像透镜86、第二成像透镜87、平面镜83（或等腰三角形棱镜）组成类似光学系统中的“4F”成像光路。
由于成像透镜具有以下性质：平行入射光聚焦在焦平面，在焦平面发出的光出射后为平行光。因此组成类似光学系统的“4F”成像光路，在第四摄像头81处接收的图像不会发生形变，在调整的时候，只需要调整第四摄像头81的竖直方向位置就能得到最佳的成像效果。
图7是使用上述影像采集平台的远程授权应用系统的结构示意图。该系统包括：多个多功能影像采集平台10，与该多功能影像采集平台相连、用于进行图像处理并发送授权申请的多个前台电脑20，用于甄别授权申请并向前台电脑返回授权指令的多个后台电脑30，以及用于存储业务链信息的多个服务器40。多个前台电脑20和与之相配对工作的多个功能影像采集平台10位于各个银行网点80，多个后台电脑30作为比前台电脑20上一级的授权终端，位于各个分行授权中心90。如图所示，此处的多台服务器为数据库服务器、影像服务器、印鉴服务器、内容管理服务器、应用服务器、信息发布服务器中的一种或多种。另外，此系统还包括一台账务主机50，以及用于连接各电脑的路由器60。多个前台电脑20、后台电脑30与服务器40之间通过银行专网70进行通讯。
前台电脑和后台电脑上均安装有仿真终端和远程授权软件。发生授权业务时，前台工作人员在其前台电脑上使用多功能影像采集平台完成影像、视频、音频、录像的采集，同时向后台电脑发送授权申请。后台电脑接收授权申请，并完成前台发送的信息的实时查看，并确认是否授权，将相关授权审核结果传递回前台电脑上，另一方面，后台电脑还用于将授权审核整个记录过程传递到服务器上进行备份和管理。服务器在日程的运作过程中，需要提供远程授权总控制服务、自动日终处理及系统的自动升级、远程授权文件服务、身份证影像文件服务等。更具体说，就是分别接收存储凭证、支票、身份证、客户头像和授权员与柜员语音、记账信息等。因而，柜员终端也需要实时将授权结束后的业务系统操作进一步提交到综合业务系统中，从而实现与综合业务系统的联动。
应当理解的是，对本领域普通技术人员来说，可以根据上述说明加以改进或变换，而所有这些改进和变换都应属于本实用新型所附权利要求的保护范围。
