摘要
文章介绍了基于人脸识别的煤矿职工考勤系统的设计原理、系统结构、设计方法和数据库系统的设计以及实现。其中最主要的部分就是面部特征的识别,首先由视频摄像头获取原始图像,然后对其进行预处理,接下来对于得到的图像针对双眼,鼻尖和嘴巴等特征进行定位,最后通过定位后的特征信息实现整体面部区域的识别功能。识别完成之后再通过和数据库中的特征信息向量进行比对,完成对于煤矿职工个体的识别。
This article introduces the design principles the design and implementation of the system architecture, design methodology and database system of the mine workers attendance system based on face recognition. One of the most important part is the recognition of the facial features, firstly,it can obtain the original image by the video camera, and then subjects to the pretreatment, the next image aiming at the eyes, nose and mouth characterized in positioning, and finally through the characteristics after positioning to achieve the identification function of the whole face region. Recognition is complete and then through the information vector and database characteristics compared to end individual identification for mine workers.
