摘要： 传统的脉搏传感器无法实现真正的多点脉搏信号检测。该文应用新型脉搏图像化检测装置采集脉搏动态图像，提出利用图像差分的方法获取多点脉搏信号。对不同差分方法实验结果的进一步比较分析表明，利用选择参考帧的差分法能够获得稳定的脉搏信号。讨论了参考帧的选择，实现了多维脉搏信号的获取。为脉搏信号检测与脉诊客观化研究提供了新的思路和方法。

Abstract: Traditional pulse sensors can not completely obtain multi-point pulse waves. By adopting the pulse image detecting instrument, the dynamic image of pulse is collected and the method of acquiring the multi-point pulse waves from image difference value is presented. Analysis and comparison of the experimental results obtained form the different ways indicate that the image difference method according to the referential image can acquire reliable pulse waves. How to choose the referential image is discussed, and acquiring multi-dimensional pulse waves from the radial artery is realized. It provides new idea and approach to detecting pulse wave and objective study on the pulse diagnosis.

Key words: pulse waves, pulse image detecting instrument, dynamic image, image difference method
