Filtered-IE23 is an adaptive, filtered method based on Implicit Euler. It uses a 2nd/3rd order embedded pair for the variable step. This repository contains a Python implementation of the numerical method. In order to run the code, we first build an environment for the dependecies and then...
Implicit Euler’s number(E). Returns: The newly created E object. Return type: E xRef() Implicit X Reference. Returns: The newly created XRef object. Return type: XRef yRef() Implicit Y Reference. Returns: The newly created YRef object. Return type: YRef zRef() Implicit Z Referen...
An extension of the first-order forward-Euler method into a two-stage, second-order Runge-Kutta method [54] involving two forward-Euler integration steps is used with an incorporated adaptive substepping. To ensure stability, two criteria control the substepping cutback size, αk: the shear ...
Moreover, the intrinsic delay of the feature matching execution is taken into account using a modified extrapolation method. Keywords: optical navigation; epipolar constraints; Kalman filter; relative terrain navigation; features-based method; visual odometry; implicit constraints...
