Description

Finds the image to world plane transformation parameters.

Filters in this group

Icon Name Description
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.

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.

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.

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.

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.
