overridevirtual

Get collision point in 2D (x and y)

Parameters

polygon	points of polygons.
search_backward	If true, return collision points with maximum s value. If false, return collision points with minimum s value.

Returns

std::optional<double> Denormalized s values along the frenet coordinate of the spline curve.

Implements math::geometry::CatmullRomSplineInterface.

getCollisionPointsIn2D()

auto math::geometry::CatmullRomSpline::getCollisionPointsIn2D	(	const std::vector< geometry_msgs::msg::Point > &	polygon,
		const bool	search_backward = false
	)		const -> std::set<double>

Note

If the spline has three or more control points.

The local_polygon is assumed to be closed

If the spline has two control points. (Same as single line segment.)

If the spline has one control point. (Same as point.)

In this case, spline is interpreted as point.

In this case, spline is interpreted as line segment.

In this case, spline is interpreted as curve.

Note

The current implementation uses index_and_s instead of structured binding (const auto [index, s_value] = getCurveIndexAndS(s)) because some tests fail when using structured binding. The root cause of these test failures is under investigation.
