orca::CartesianLineFeature2d Class Reference [FeatureMap2d] Inherits orca::Feature2d. Inheritance diagram for orca::CartesianLineFeature2d: [legend]List of all members. Public Attributes double  rho   mean rho double  alpha   mean alpha PointCovariance2d  c   covariance of (rho,alpha) CartesianPoint2d  start   start of line CartesianPoint2d  end   end of line bool  startSighted   Is the reported start point the actual extent of the line? bool  endSighted   Is the reported end point the actual extent of the line? Detailed Description A line feature. Infinite lines are parameterised by (rho,alpha), which describes the vector from the origin which meets the line at 90deg: rho is the length of this vector, and alpha is the angle the vector makes with the x-axis (in (-pi,pi]). This information is augmented with info that describes the fact that the line is a finite segment, visible from one direction only. By definition, a line is visible iff the start appears to the right of the end. The documentation for this class was generated from the following file: featuremap2d.ice
