Camera Calibration

Select a function from the list below.

Icon Name Description / Applications Modules
AnnotateGridPoints

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


Recognition of a custom regular grid for the purpose of camera calibration.

Calibration
AnnotateGridPoints_Ransac

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

Calibration
CalibrateCamera_LineScan

Finds the line scan camera intrinsic parameters from calibration grid.


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

Calibration
CalibrateCamera_Pinhole

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.

Calibration
CalibrateCamera_Telecentric

Finds the telecentric camera intrinsic parameters from calibration grids.


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

Calibration
CalibrateWorldPlane_Default

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.

Calibration
CalibrateWorldPlane_Labeled

Finds the image to world plane transformation parameters using sparse world coordinate information, i.e. world coordinates are known for only a few points of the grid.


Image to world coordinates transformations, also useful for image rectification where exact bounds of output image are important, e.g. stitching.

Calibration
CalibrateWorldPlane_Manual

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.

Calibration
CalibrateWorldPlane_Multigrid

Finds the image to world plane transformation parameters using multiple grids, using sparse world coordinate information.


Covers cases where a single grid spanning whole working area on a world plane is not feasible. Also useful when high accuracy is desired.

Calibration
CalibrateWorldPlane_OffgridOrigin

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.

Calibration
ConvertRectificationMap

Converts a rectification map to a different format.

Calibration
CreateRectificationMap_Advanced

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.

Calibration
CreateRectificationMap_Basic

Computes a spatial map for removing lens and perspective distortion directly from an image containing circles calibration pattern. Internally uses a pinhole camera model with polynomial lens distortion.


Quick and easy one-step calibration for basic removal of lens and perspective distortions.

Calibration
CreateRectificationMap_PixelUnits

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.

Calibration
CreateRectificationMap_WorldUnits

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


Specification of output geometry in world units is especially useful in image stitching.
