中文摘要: 胎儿心率检测是围产期常规检测,是评估孕妇和胎儿健康的主要生理指标.相对现有的接触式胎心检测技术,本文提出一种更为便捷,成本低廉的非接触式胎儿心率提取算法.首先基于欧拉视频颜色放大技术,对视频中颜色信号放大.其次,利用光电容积脉搏波描记法提取血液容积脉冲信号,并对母体噪声进行分离,计算功率谱密度提取.将采集到的胎心率,与医院专用胎心设备检测的结果进行定量分析,数据表明可以达到96%的准确度.

Abstract:Fetal Heart Rate (FHR) is a routine perinatal test and one of the main physiological indices to evaluate the health status of pregnant women and fetuses. In contrast to existing contact FHR detection technology, we propose a convenient and inexpensive noncontact FHR monitoring method based on Eulerian video magnification. The color signal in video is amplified and PhotoPlethysmoGraphy (PPG) is used to extract microvascular blood volume pulsar signal after removing maternal noise. The FHR can be estimated by calculating the power spectral density of the signal. Experiments show that the accuracy of detecting FHR can reach 96% using clinical measured data as the standard.
