Abstract

This study is to construct a non-contact pulse automatic positioning measurement system for Traditional Chinese Medicine (TCM) using optical triangulation measurements. The system consists of a linear laser, a CMOS image sensor and image analysis software. The linear laser is projected on the pulse beat location on the wrists; the CMOS image sensor records the process and the software analyzes the images. The program mainly uses the optical centroid and fast Fourier transform (FFT) principles to calculate centroid changes (pulse amplitude changes) from the images taken by the CMOS image sensor. It returns the positions of cun, guan and chi pulses automatically in terms of the amplitudes and the signals are then transformed from the time domain (time-amplitude) into the frequency domain (frequency-amplitude) via FFT to obtain the waveforms and frequencies of the cun, guan and chi pulses. It successfully extracts the data from the TCM pulse reading and can be a medical aid system for TCM. Combining the advantages of optical measurement and computer automation, this system provides a non-contact, easy to operate, fast in detection and low-cost equipment design.

摘要

本研究旨在利用光学三角测量法构建一种用于中医的非接触式脉搏自动定位测量系统。该系统由线性激光器、CMOS图像传感器和图像分析软件组成。线性激光器投射在手腕上的脉搏跳动位置；CMOS图像传感器记录该过程，软件对图像进行分析。该程序主要利用光学质心和快速傅里叶变换（FFT）原理，根据CMOS图像传感器拍摄的图像计算质心变化（脉搏幅度变化）。它根据幅度自动返回寸、关、尺脉搏的位置，然后通过FFT将信号从时域（时间-幅度）转换到频域（频率-幅度），以获得寸、关、尺脉搏的波形和频率。它成功地从中医脉象读取中提取数据，可成为中医的辅助医疗系统。该系统结合了光学测量和计算机自动化的优点，提供了一种非接触、操作简便、检测快速且成本低廉的设备设计。
