Description

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.
