Member Function Documentation

void BoxRelative::calc (  )  [virtual]

Calculate position data.

Call this method if all relevant data (set(Radius|Center|PanTilt)) has been set, after this valid data can be retrieved via get*

Implements RelativePositionModel.

References calc_unfiltered().

void BoxRelative::calc_unfiltered (  )  [virtual]

Calculate data unfiltered.

Same as calc(), but without any filtering (i.e. no Kalman filter).

Implements RelativePositionModel.
