中文摘要：

利用前期研制的基于单CCD（charge coupled device,电子耦合器件）的脉搏多维信息测量装置,采集得到脉搏动态时变图像序列。重新设计传感器触头为绘有网格点的软性双层薄膜结构,在此基础上,建立了测量原理模型,论证了该装置获取脉搏多维信息的可行性。随后,通过对网格点图像的处理,成功提取了脉搏波的形态、频率、节律及脉宽信息,所得结果与测量模型分析一致。研究表明,该系统能够有效提取多维脉搏特征信息,为脉搏信息的检测和表征提供了一种全新的手段和方法。

英文摘要：

By using the existing measuring device for multidimensional characteristic information extraction of pulse wave based on CCD（charge coupled device） , the dynamic pulse images were collected. A tactile detector with a soft dual-layer composite film, which was painted the grid formed by small round dots, was designed successfully. The principle of the measurement was modeled, and the feasibility of multidimensional characteristic information extraction of pulse wave was discussed. Using image processing technology, the pulse information such as shapes, frequency, rhythm and width could be detected from the grid images. The outcome of processing was consistent with the model analysis. The results show that by using the system, the multidimensional characteristic pulse information can be effectively detected, which provides a new approach to detect and express the pulse information.
