Answering my own question. There isn't such a function, but finding the (x, y) bounds and Homography matrices from ComputeRectificationParams.m, then using the Homography and undistortion equations, then using interp2 to move forward gives accurate rectification. See https://www.mathworks.com/help///visionhdl/ug/stereoscopic-rectification.html for details.
Is there a Matlab version of the OpenCV function initUndistortRectifyMap()?

I need the undistortion and rectification transformation maps for a project.

Hi Yuval, I am also looking for the mapx and mapy calculation like in OpenCV cvInitUndistortRectifyMap().
How did you solve that with using homography matrix and x,y bounds?
I received these information by using paramStruct = toStruct(stereoParams) and get H1, H2, XBounds, YBounds, but dont have any idea how to proceed now. Do you have any code to share?
Thx
Fatih

Hi,
The rectifyStereoImages function returns undistorted and rectified versions of the input images using the stereo parameters. I think, this is what you are looking for. Please refer to the documentation of the same to know more about the function.
Thanks.
