Returns individual fields of a 3D position.

Select a subset of the given points that forms a grid and assign 2D indices to them.

Finds the camera intrinsic parameters from calibration grids. Uses pinhole camera model (perspective camera).

Computes camera parameters which need to be calculated only once for each camera, and are a prerequisite for other calibration filters.

Finds the image to world plane transformation parameters from world plane calibration grid. World plane origin and axes are unspecified.

Useful for cases where the position of world plane origin is not important, e.g. distance measurements on a world plane, or image rectification for perspective removal.

Finds the image to world plane transformation parameters. Image and their corresponding world points are directly specified (no grid needed).

Prepares transformation parameters for image to world coordinate transformations or image rectification without the need for a world plane calibration grid.

Finds the image to world plane transformation matrix, with world origin and axes specified in the image coordinates.

Rather rarely seen special cases where absolute world plane coordinates cannot be specified in terms of calibration grid, but the location of world plane origin is still required. When in doubt, use the CalibrateWorldPlane_Labeled filter.

Computes a spatial map for transforming distorted images to rectified images defined in world coordinate plane. Allows for flexible definition of output geometry.

Rarely seen special edge cases. Usually it is sufficient to use CreateRectificationMap_PixelUnits or CreateRectificationMap_WorldUnits filters.

Computes a spatial map for transforming distorted images to rectified images defined in world coordinate plane. Defines the output geometry in pixels.

Specification of fixed output geometry allows for constant environment even when recalibration is performed.

Detects a chessboard calibration grid on the image, and returns calibration points where 4 chessboard squares meet.

Select a subset of the given points that forms a grid.
