Detailed Description

Basic test of RauchTungStriebelSmoother.

This test sets up a linear model for testing the Rauch-Tung-Striebel (RTS) smoother implementation. It may be validated against the Kalman filter and kalman smoother results.

Results are output into files as follows:

results/RauchTungStriebelHarness_actual.out

Actual state of the robot at each time. Columns are as follows:

• time
• x coordinate
• y coordinate
• orientation (radians)

results/RauchTungStriebelHarness_meas.out

Measurement at each time step. Columns are as follows:

• time
• measurement

results/RauchTungStriebelHarness_filter.out

Predicted state (filtered) at each time step. Columns are as follows:

• time
• mean x coordinate
• mean y coordinate
• mean orientation
• The remaining columns give the covariance matrix between the above state variables.

results/RauchTungStriebelHarness_smooth.out

Predicted state (smoothed) at each time step. Columns are as follows:

• time
• mean x coordinate
• mean y coordinate
• mean orientation
• The remaining columns give the covariance matrix between the above state variables.

Note that as the smoothing is performed in a backwards pass, this file has entries in reverse time order.
