Software architecture

Driving strategy: Two different driving strategies are examined:

Mid-line: By use of a hough-transform is a visualisation made of the surroundings of pico. By use of this visualisation a centerline trajectory can be determined and used as setpoint trajectory for pico.

Wall-tracking: Not the centerline is chosen as the to be controlled setpoint trajectory but the distance to the right wall is chosen as input. Remark: Usefull for the 'always-right'-strategy.

Method Mid-line Wall-tracking
Simplicity - +
Robustness + +
Flexibility + -
CPU time + ++

Midline strategy: Complicated trajectory planning, but flexible in corner detection.

Wall tracking strategy: Basic trajectory planning, only right wall is important.
