描述
distance_point_pluecker_linedistance_point_pluecker_lineDistancePointPlueckerLineDistancePointPlueckerLineDistancePointPlueckerLinedistance_point_pluecker_line calculates the orthogonal
distance between 3D points and 3D lines.
The result is returned in DistanceDistanceDistanceDistancedistancedistance.
The input tuples can define 1 or n points
and lines, respectively.
The points are specified by
(PointXPointXPointXPointXpointXpoint_x, PointYPointYPointYPointYpointYpoint_y, PointZPointZPointZPointZpointZpoint_z).
The lines are given in Plücker coordinates
(LineDirectionXLineDirectionXLineDirectionXLineDirectionXlineDirectionXline_direction_x, LineDirectionYLineDirectionYLineDirectionYLineDirectionYlineDirectionYline_direction_y, LineDirectionZLineDirectionZLineDirectionZLineDirectionZlineDirectionZline_direction_z)
and
(LineMomentXLineMomentXLineMomentXLineMomentXlineMomentXline_moment_x, LineMomentYLineMomentYLineMomentYLineMomentYlineMomentYline_moment_y, LineMomentZLineMomentZLineMomentZLineMomentZlineMomentZline_moment_z).
For the definition of Plücker coordinates, see
“Solution Guide III-C - 3D Vision”.
Let denote the point
(PointXPointXPointXPointXpointXpoint_x, PointYPointYPointYPointYpointYpoint_y, PointZPointZPointZPointZpointZpoint_z),
the direction
(LineDirectionXLineDirectionXLineDirectionXLineDirectionXlineDirectionXline_direction_x, LineDirectionYLineDirectionYLineDirectionYLineDirectionYlineDirectionYline_direction_y, LineDirectionZLineDirectionZLineDirectionZLineDirectionZlineDirectionZline_direction_z),
and the moment
(LineMomentXLineMomentXLineMomentXLineMomentXlineMomentXline_moment_x, LineMomentYLineMomentYLineMomentYLineMomentYlineMomentYline_moment_y, LineMomentZLineMomentZLineMomentZLineMomentZlineMomentZline_moment_z)
of the Plücker line.
Furthermore, let denote the distance DistanceDistanceDistanceDistancedistancedistance. Then,
,
where denotes the cross product of two vectors.
