| 摘 要： | 应用自制的基于单目CCD摄像头的脉搏图像传感器采集桡动脉动态脉搏图像。在信息采集过程中,需要对人手腕-探头-CCD三者之间的相对位置进行调整,以利于图像处理、脉搏信号的提取以及脉象分析。本文结合自制传感器,以＂获取最优脉搏图像＂为标准,分析总结对该传感器而言较为合理而又相对简单易行的定位规则。实验表明,＂最佳取脉压力＂和＂平面最佳取脉位置＂这两个指标可以帮助传感器寻找到获取最清晰脉搏图像的位置。

| Abstract: | Use self-made pulse image sensor based on monocular CCD camera in acquiring radial pulse images.Adjusting relative positions of wrist-detector-CCD while collecting information will be beneficial to image processing,pulse-signals extracting and pulse-shape analysis.A comparatively reasonable and convenient method based on the principle of 'best pulse-shape image'for position-setting applied to this situation is proposed in this paper.Experiments show that two indices named 'the best pulse-taking pressure' an... |
