Function Documentation

◆ ransac_detect_2D_lines()

template<typename NUMTYPE >

void mrpt::math::ransac_detect_2D_lines	(	const CVectorDynamic< NUMTYPE > &	x,
		const CVectorDynamic< NUMTYPE > &	y,
		std::vector< std::pair< size_t, TLine2D >> &	out_detected_lines,
		const double	threshold,
		const size_t	min_inliers_for_valid_line = `5`
	)

Fit a number of 2-D lines to a given point cloud, automatically determining the number of existing lines by means of the provided threshold and minimum number of supporting inliers.

Parameters

out_detected_lines	The output list of pairs: number of supporting inliers, detected line.
threshold	The maximum distance between a point and a temptative line such as the point is considered an inlier.
min_inliers_for_valid_line	The minimum number of supporting inliers to consider a line as valid.
