class mrpt::opengl::CEllipsoidInverseDepth3D

An especial “ellipsoid” in 3D computed as the uncertainty iso-surfaces of a (inv_range,yaw,pitch) variable.

The parameter space of this ellipsoid comprises these variables (in this order):

  • inv_range: The inverse distance from the sensor to the feature.

  • yaw: Angle for the rotation around +Z (“azimuth”).

  • pitch: Angle for the rotation around +Y (“elevation”). Positive means pointing below the XY plane.

This parameterization is based on the paper:

  • Civera, J. and Davison, A.J. and Montiel, J., “Inverse depth parametrization for monocular SLAM”, T-RO, 2008.

This class expects you to provide a mean vector of length 3 and a 3x3 covariance matrix, set with setCovMatrixAndMean().

Please read the documentation of CGeneralizedEllipsoidTemplate::setQuantiles() for learning the mathematical details about setting the desired confidence interval.
