kalman滤波算法与alpha-beta滤波算法的比较，通过比较，验证两种算法各自的优缺点。(Comparison, Kalman filtering algorithm and alpha-beta filtering algorithm by comparing the advantages and disadvantages of verification, two algorithms. )

该段代码可用于加速度信号的积分求得位移。使用的是频域积分方法，设置合适的上下限截止频率可较好的复现实际路面的位移高程。(This code can be used for integration of the acceleration signal obtained displacement. Using a frequency-domain integral method, set the appropriate upper and lower cutoff frequency displacement elevation better reproduce the actual road.)
