测距仪测距的过程中，由于受到仪器本身的系统误差以及外界环境影响，会造成测距精度的下降。为了提高测距的精度，我们需要对测距的结果进行改正，可以分为三种类型的改正：仪器常数的改正、气象改正和倾斜改正。(Rangefinder ranging process, due to systematic errors in the instrument itself and the external influences, ranging accuracy will result in a decline. In order to improve ranging accuracy, we need to correct the results of the distance, can be divided into three types of corrections: the correction instrument constant, meteorological correction and inclination correction.)

An implementation of Unscented Kalman Filter for nonlinear state estimation. (Nonlinear state estimation is a challenge problem. The well-known Kalman Filter is only suitable for linear systems. The Extended Kalman Filter (EKF) has become a standarded formulation for nonlinear state estimation. However, it may cause significant error for highly nonlinear systems because of the propagation of uncertainty through the nonlinear system. The Unscented Kalman Filter (UKF) is a novel development in the field. The idea is to produce several sampling points (Sigma points) around the current state estimate based on its covariance. Then, propagating these points through the nonlinear map to get more accurate estimation of the mean and covariance of the mapping results. In this way, it avoids the need to calculate the Jacobian, hence incurs only the similar computation load as the EKF. For tutorial purpose, this code implements a simplified version of UKF formulation, where we assume both the process and measurement noises are additive to avoid augment of state and a)
