Package boofcv.factory.fiducial

Class ConfigHammingGrid

java.lang.Object

boofcv.factory.fiducial.ConfigHammingGrid

All Implemented Interfaces:

Configuration, Serializable

public class ConfigHammingGrid
extends Object
implements Configuration

Defines the calibration pattern based on hamming square fiducials where each square is a marker that can be uniquely identified. These are typically used for multi camera calibration and are robust against partial occlusions. Aruco Grids are a member of this family.
