Class DistanceHomographySq

java.lang.Object

boofcv.alg.geo.robust.DistanceHomographySq

All Implemented Interfaces:

org.ddogleg.fitting.modelset.DistanceFromModel<georegression.struct.homography.Homography2D_F64,AssociatedPair>

public class DistanceHomographySq
extends java.lang.Object
implements org.ddogleg.fitting.modelset.DistanceFromModel<georegression.struct.homography.Homography2D_F64,AssociatedPair>

Computes the Euclidean error squared between 'p1' and 'p2' after projecting 'p1' into image 2. Input can be in pixels or normalized image coordinates, but the error for normalized image coordinates doesn't have a physical meaning.

error = (p2'.x - p2.x)² + (p2'.y - p2.y)², where p2' is the predicted location and p2 is the observed location.
