Embedded laboratory access control face recognition system design

为加强对实验室门禁系统的控制,降低门禁程序的误检率,对嵌入式实验室门禁人脸识别系统进行设计与验证。简述系统的构建需求,有针对性地进行嵌入式系统总体结构设计。基础电路中接入0K6410核心板,关联前后识别端口的同时,植入图像采集装置,完成系统硬件的设计;建立嵌入式交叉识别编译环境,对所识别的图像预处理并设计定位指令,关联ORL嵌入式人脸数据库,完成系统软件的设计。系统测试结果表明:针对于静态检测识别环境和动态检测识别环境下的测试,在50名用户的识别测验后,得出的误检率均控制在15%以下,表明在实际嵌入式人脸识别过程中,识别误差小、可控、识别速度快、更易调整,具有实际的应用价值。

In order to strengthen the control of the laboratory access control system and reduce the false detection rate of the access control procedures,the embedded laboratory face recognition system of the laboratory access control system is designed and verified.Simply describe the construction requirements of the system,and design the overall structure of the embedded system.The 0K6410 core board is connected to the basic circuit to complete the system hardware design,establish an embedded cross⁃recognition compilation environment,pre⁃process the identified image and design positioning instructions,and associate the ORL embedded face database to complete the design of the system software.System test results show that:for static detection recog⁃nition environment and dynamic detection recognition environment test,after 50 users identification test,the error rate control below 15%,shows that in the process of actual embedded face recognition,identification error is small,controllable,identify fast,easier to adjust,has the practical application value.
