python_motion_planning.curve_generation.bezier_curve.Bezier

Bases: Curve

Class for Bezier curve generation.

Parameters:

Name	Type	Description	Default
step	float	Simulation or interpolation size	required
offset	float	The offset of control points	required

Examples:

Python Console Session

>>> from python_motion_planning.curve_generation import Bezier
>>>     points = [(0, 0, 0), (10, 10, -90), (20, 5, 60)]
>>> generator = Bezier(step, offset)
>>> generator.run(points)

bezier(t, control_points)

Calculate the Bezier curve point.

Parameters:

Name	Type	Description	Default
t	float	scale factor	required
control_points	list[tuple]	control points	required

Returns:

Name	Type	Description
point	array	point in Bezier curve with t

generation(start_pose, goal_pose)

Generate the Bezier Curve.

Parameters:

Name	Type	Description	Default
start_pose	tuple	Initial pose (x, y, yaw)	required

Returns:

Name	Type	Description
x_list	list	x of the trajectory
y_list	list	y of the trajectory
yaw_list	list	yaw of the trajectory

getControlPoints(start_pose, goal_pose)

Calculate control points heuristically.

Parameters:

Name	Type	Description	Default
