Detailed Description

A path smoother implementation using Savitzky Golay filters.

Member Function Documentation

bool nav2_smoother::SavitzkyGolaySmoother::smooth	(	nav_msgs::msg::Path &	path,
		const rclcpp::Duration &	max_time
	)

overridevirtual

Method to smooth given path.

Parameters

path	In-out path to be smoothed
max_time	Maximum duration smoothing should take

Returns: If smoothing was completed (true) or interrupted by time limit (false)

bool nav2_smoother::SavitzkyGolaySmoother::smoothImpl	(	nav_msgs::msg::Path &	path,
		bool &	reversing_segment
	)

protected

Smoother method - does the smoothing on a segment.

Parameters

path	Reference to path
reversing_segment	Return if this is a reversing segment
costmap	Pointer to minimal costmap
max_time	Maximum time to compute, stop early if over limit
