cvInitUndistortRectifyMap Method (cameraMatrix, distCoeffs, R, newCameraMatrix, mapx, mapy)

www.emgu.com/wiki

This function is an extended version of cvInitUndistortMap. That is, in addition to the correction of lens distortion, the function can also apply arbitrary perspective transformation R and finally it can scale and shift the image according to the new camera matrix

Declaration Syntax

Parameters

cameraMatrix (IntPtr): The camera matrix A=[fx 0 cx; 0 fy cy; 0 0 1]

distCoeffs (IntPtr): The vector of distortion coefficients, 4x1, 1x4, 5x1 or 1x5

R (IntPtr): The rectification transformation in object space (3x3 matrix). R1 or R2, computed by cvStereoRectify can be passed here. If the parameter is NULL, the identity matrix is used

newCameraMatrix (IntPtr): The new camera matrix A'=[fx' 0 cx'; 0 fy' cy'; 0 0 1]

mapx (IntPtr): The output array of x-coordinates of the map

mapy (IntPtr): The output array of y-coordinates of the map
