摘　　要：为了从中医脉象图中获取更多有价值的信息,本文在总结传统加速度脉象图计算的基础上提出了一种新的高精度加速度脉象图计算算法,能够适应大数据量、高分辨率的全数字脉象图分析要求,优化了加速度脉象图绘制流程,减少了噪音对数据分析的影响,提高了图像细节辨别能力。同时还运用频谱分析手段对高精度加速度脉象图进行分析,克服了传统加速度脉象数据噪声多、损失大的缺点,发现了新的中医平脉、滑脉、弦脉的加速度频谱图特征点,能够对中医脉象图在其加速度计算频域层面进行识别。In order to get more pulse diagram valuable information, we summarized the traditional acceleration in the pulse chart based on the calculation of a new highprecision calculation of the acceleration pulse graph algorithms, be ing suitable for a large amount of data to adapt to requirements of highresolution digital pulse diagram analysis, opti mizing the acceleration pulse mapping process, reducing the impact of noise on data analysis, and improving the abili ty to distinguish details of the image. In addition, we used the spectrum analysis diagram for highprecision accelera tion pulse. By doing so, we overcomed the traditional acceleration noise in the pulse data as the large loss, we found flat pulse, slippery pulse, taut pulse acceleration spectrum of feature points in the new Chinese medical traditional pulses. We then were able to recognize the pulse diagram calculated at the acceleration level to identify the frequency domain.
