众所周知,在高速摄影测量结果的数据处理中,为压缩偶然误差而采用平滑技术;为获得目标的分速度、速度、分加速度、加速度以及角速度等等,而采用微分手段。对数据为离散点的平滑与两个因素(p,n)有关,而微分则与三个因素有关(p,nh)。 p:利用最小二乘法拟合时多项式的阶数; It is well known that in the data processing of high-speed photogrammetry results, a smoothing technique is adopted for compressing accidental errors, and a derivative method is used to obtain the target’s speed, acceleration, acceleration, angular velocity and the like. The smoothness of the data for discrete points is related to two factors (p, n), while the derivative is related to three factors (p, nh). p: the order of the polynomial fitted by the least square method;
