Detailed Description

Utility class for estimation of compensation parameters of lens-distortion.

Internally, this is a wrapper class around OpenCV's cvCalibrateCamera2. For the calibration, a set of "grids", each consisting of a set of 2D-image to 3D-object coordinates is needed. The 3D object coordinates are assumed to be coplanar and to be normalized to the range [0,1] in the remaining x and y dimensions. Theses normalized x/y coordinates are defined by the LensUndistortionCalibrator::GridDefinition class.
