java.lang.Object

boofcv.alg.geo.calibration.Zhang99ComputeTargetHomography

public class Zhang99ComputeTargetHomography
extends java.lang.Object

Given a description of the calibration grid and a set of observations compute the associated Homography. First a linear approximation is computed follow by non-linear refinement. Part of calibration process described in [1].

Method Detail

computeHomography

public boolean computeHomography(java.util.List<georegression.struct.point.Point2D_F64> observedPoints)

Computes the homography from a list of detected grid points in the image. The order of the grid points is important and must follow the expected row major starting at the top left.

Parameters:

observedPoints - List of ordered detected grid points in image pixels.

Returns:

True if it computed a Homography and false if it failed to compute a homography matrix.

getHomography

public org.ejml.data.DenseMatrix64F getHomography()

Returns a copy of the found homography matrix.

Returns:

Homography matrix.
