摘要: 针对煤矿采用的打卡记名等常规考勤方法存在的考勤信息不准确问题，采用人脸识别技术设计了一种煤矿调度室员工自动签到系统，介绍了系统的总体设计方案及人脸识别算法。该系统首先采集人脸图像并进行预处理，然后采用Adaboost算法进行人脸检测，最后采用POEM+分块PCA算法及最近邻法分类器对采集到的人脸图像进行识别，以实现调度室员工的自动签到功能，并对考勤状况加以记录，为员工考核提供依据。Abstract: For the problem of attendance information inaccuracy of regular attendance methods in coal mine like card punching method, an automatic sign-in system for dispatch room staff of coal mine was designed by use of face recognition technology, and the whole design scheme and face recognition algorithm of the system were introduced. The system firstly collects and pre-processes the face image, then detects face by use of Adaboost algorithm, and lastly recognizes the detected face through POEM + block PCA algorithm and nearest neighbor classifier. The system realizes functions of automatic sigh-in and attendance record of dispatch room staff of coal mine, which provides basis information for staff appraisal.
