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

◆ WTrajectorySpheres()

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
pathList of poses on a trajectory. Takes std::vector<Affine<T>> with T == [float | double]
line_lengthMax length of the lines which point to previous position
radiusRadius of the spheres.
fromColor for first sphere.
toColor for last sphere. Intermediate spheres will have interpolated color.
