摘要

这项工作涉及使用光电容积脉搏波成像(PPGI)和低成本网络摄像机原理从面部区域进行非接触式心率检测。该算法在MATLAB环境下实现。首先利用合适的人脸跟踪器对人脸进行跟踪，然后从皮肤中获取信号，并对信号进行处理。得到心率后，与传统接触光容积脉搏波(PPG)得到的心率信号进行比较。获得的心率(BPM)可用于教学过程中的压力评估。

Non-Contact Detection of Vital Parameters with Optoelectronic Measurements under Stress in Education Process

This work deals with contactless detection of heart rate from facial region using the principles of photoplethysmography imaging (PPGI) and low-cost web camera. Our proposed algorithm was realized in MATLAB environment. Using suitable face trackers, the face is tracked, then the signal is obtained from skin and subsequently the signal processing was performed. After obtaining heart rate, it is compared with heart rate signal obtained from traditional contact photoplethysmography (PPG). Obtained heart rate (BPM) can be used in stress evaluation in educational process.
