基于图像传感器的亚健康脉搏信号研究

Study of the Pulse Signal of the Sub-health Status with An Image Sensor

本文旨在探索人体亚健康状态的脉搏信号的特点,为亚健康诊断及疾病的早期发现和预防提供客观依据。研究使用自主研制的脉搏图像传感器,分别采集健康人员和亚健康人员的脉搏图像信号,对其进行图像处理以及提取脉宽、脉长、脉管轴心位移等特征。通过对结果的对比研究和分析,探明亚健康人员的脉宽和脉长均比健康人员的大,且亚健康人员的脉管轴心位移比健康人员的轴心位移波动大。研究表明,健康人员和亚健康人员的脉搏特征有明显的差异。

With the fast social development, the accelerating life pace and the improved living quality, higher standards are putting forward to evaluate the health status. Consequently the key of modern medical treatment is shifting from disease diagnosis and treatment to disease prevention and control. This study aimed to explore the features of the human sub-health pulse signals to provide an objective basis of sub-health diagnosis as well as its early detection and prevention. Pulse image signals were collected by a serf-made pulse image sensor. Image processing was conducted, and features were extracted, including the pulse width, length and vascular axis displacement. The contrastive analysis of the collected data showed that the sub-heahh subjects had larger pulse width and length than the healthy ones, together with a more fluctuant vascular axis displacement. The results showed that the pulse features are significantly different between the healthy and sub-health subjects.
