描述
points_to_pluecker_linepoints_to_pluecker_linePointsToPlueckerLinePointsToPlueckerLinePointsToPlueckerLinepoints_to_pluecker_line converts the 3D line given by the
two points (Point1XPoint1XPoint1XPoint1Xpoint1Xpoint_1x, Point1YPoint1YPoint1YPoint1Ypoint1Ypoint_1y, Point1ZPoint1ZPoint1ZPoint1Zpoint1Zpoint_1z)
and (Point2XPoint2XPoint2XPoint2Xpoint2Xpoint_2x, Point2YPoint2YPoint2YPoint2Ypoint2Ypoint_2y, Point2ZPoint2ZPoint2ZPoint2Zpoint2Zpoint_2z) to
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”.
All input tuples must be of same length.
Let denote the first point
(Point1XPoint1XPoint1XPoint1Xpoint1Xpoint_1x, Point1YPoint1YPoint1YPoint1Ypoint1Ypoint_1y, Point1ZPoint1ZPoint1ZPoint1Zpoint1Zpoint_1z)
and the second point
(Point2XPoint2XPoint2XPoint2Xpoint2Xpoint_2x, Point2YPoint2YPoint2YPoint2Ypoint2Ypoint_2y, Point2ZPoint2ZPoint2ZPoint2Zpoint2Zpoint_2z) on the line.
To compute the line direction , the
vector and
its length are computed.
If , the points do not define a line
and an error is returned.
The line direction is given by
.
The line moment is given by the cross product
。
