Function opencv::sfm::normalize_points

pub fn normalize_points(
    points: &dyn ToInputArray, 
    normalized_points: &mut dyn ToOutputArray, 
    t: &mut dyn ToOutputArray
) -> Result<()>

This function normalizes points (non isotropic).

Parameters

• points: Input vector of N-dimensional points.
• normalized_points: Output vector of the same N-dimensional points but with mean 0 and average norm .
• T: Output 3x3 transform matrix such that , where are the points to normalize and the normalized points.

Internally calls @ref preconditionerFromPoints in order to get the scaling matrix before applying @ref applyTransformationToPoints. This operation is an essential step before applying the DLT algorithm in order to consider the result as optimal.
