Method Details

estimateLensDistortion

protected double[] estimateLensDistortion(Camera cam,
 ViewTransform[] views,
 Pnt2d[] modelPts,
 Pnt2d[][] obsPts)

Estimates the lens distortion from multiple views, starting from an initial (linear) camera model.

Parameters:

cam - the initial (linear) camera model

views - a sequence of extrinsic view transformations

modelPts - the set of 2D model points (on the planar calibration target)

obsPts - a sequence of 2D image point sets, one set for each view

Returns:

a vector of lens distortion coefficients
