Class GenerateScaleTranslate2D

java.lang.Object

boofcv.alg.sfm.robust.GenerateScaleTranslate2D

All Implemented Interfaces:

org.ddogleg.fitting.modelset.ModelGenerator<ScaleTranslate2D,boofcv.struct.geo.AssociatedPair>

public class GenerateScaleTranslate2D
extends java.lang.Object
implements org.ddogleg.fitting.modelset.ModelGenerator<ScaleTranslate2D,boofcv.struct.geo.AssociatedPair>

Estimates a ScaleTranslate2D from two 2D point correspondences. The transform will take a point from p1 to p2. The algorithm works by finding the centroid of p1 and p2. Scale is found by finding the average change in vector length between p1 and p2 and the centroids. Translation is found by the translation between the two centroids, adjusted for change in scale. If more than two points are provided the extra points are ignored.
