Class KeyPointsCircleHexagonalGrid

java.lang.Object

boofcv.alg.fiducial.calib.circle.KeyPointsCircleHexagonalGrid

public class KeyPointsCircleHexagonalGrid
extends Object

Computes key points from an observed hexagonal circular grid. Each key point is defined as the circle's true geometric center. The center (green dot) is found by detecting tangent points between two neighboring circles (yellow dots) and then finding the intersection of all the lines created by connecting adjacent tangent points. Tangent points are the same under perspective distortion and the same can be said for the intersection of their lines.
