Detailed Description

This 3D Widget represents a trajectory using spheres and lines.

where spheres represent the positions of the camera, and lines represent the direction from previous position to the current. :

Constructor & Destructor Documentation

cv::viz::WTrajectorySpheres::WTrajectorySpheres	(	InputArray	path,
		double	line_length = `0.05`,
		double	radius = `0.007`,
		const Color &	from = `Color::red()`,
		const Color &	to = `Color::white()`
	)

Constructs a WTrajectorySpheres.

Parameters

path	List of poses on a trajectory. Takes std::vector<Affine<T>> with T == [float \| double]
line_length	Max length of the lines which point to previous position
radius	Radius of the spheres.
from	Color for first sphere.
to	Color for last sphere. Intermediate spheres will have interpolated color.

Member Function Documentation

void cv::viz::Widget3D::applyTransform ( const Affine3d & transform )

inherited

Transforms internal widget data (i.e.

points, normals) using the given transform.

Parameters

transform Specified transformation to apply.

template<typename _W >

_W cv::viz::Widget::cast ( )

inherited

Casts a widget to another.

// Create a sphere widget
viz::WSphere sw(Point3f(0.0f,0.0f,0.0f), 0.5f);
// Cast sphere widget to cloud widget
viz::WCloud cw = sw.cast<viz::WCloud>();

Note: 3D Widgets can only be cast to 3D Widgets. 2D Widgets can only be cast to 2D Widgets.
