Class KeyPointsCircleRegularGrid

java.lang.Object

boofcv.alg.fiducial.calib.circle.KeyPointsCircleRegularGrid

public class KeyPointsCircleRegularGrid
extends Object

Computes key points from an observed regular circular grid. Each circle has 4 key points at the grid aligned top, bottom, left, and right side of the circle. These key points are found using tangent points between adjacent circles. Tangent points are the same under perspective distortion and the same can be said for the intersection of their lines. When more than one intersection is at the same location the average is found
