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 .

运行信息
