gtsam::OrientedPlane3 Class Reference

Represents an infinite plane in 3D, which is composed of a planar normal and its perpendicular distance to the origin. Currently it provides a transform of the plane, and a norm 1 differencing of two planes. Refer to Trevor12iros for more math details. More...

Dimensionality of tangent space = 3 DOF.

Definition at line 103 of file OrientedPlane3.h.

◆ dim()

size_t gtsam::OrientedPlane3::dim ( ) const
inline

Dimensionality of tangent space = 3 DOF.

Definition at line 108 of file OrientedPlane3.h.

◆ distance()

double gtsam::OrientedPlane3::distance ( OptionalJacobian< 1, 3 >  H = {}) const
inline

Return the perpendicular distance to the origin.

Definition at line 132 of file OrientedPlane3.h.

◆ equals()

bool gtsam::OrientedPlane3::equals ( const OrientedPlane3 s,
double  tol = 1e-9

◆ errorVector()

Vector3 gtsam::OrientedPlane3::errorVector ( const OrientedPlane3 other,
OptionalJacobian< 3, 3 >  H1 = {},
