Ok guys, first thanks a lot for your time and your help. Now lets go to the next step. I have computed the intrinsic, extrinsic coeffs and the rotation, translation matrices from stereoCalibrate(). Moreover I have extracted the R1,R2,P1,P2,Q matrices from the stereoRectify() (not sure if are needed):

Now before I try to align the RGB with the depth, I would like to do that with the IR image as I am showing in my initial post. However, I am quite confused how to do this. According to the documentation initUndistortRectifyMap() should do that but my output is really strange as you can see:

while if I use the common undistort() function I am getting a better result:
distorted:
Undistorted:
my other question here is can I get my undistorted image without being zoomed in? and in the surounding pixels being black. In general how do I align the rgb with the ir image and then apply the distortion again back (I guess the same procedure will be followed for the depth image).

Ok guys, first thanks a lot ok I tried to obtain some better intrinsic and dist coeffs for your time the rgb camera. Then using the undistortion() function I undistorted the images and your help. Now lets go finally multiplying the dist coeffs with -1 and reapplying the undistortion() function I reapplied the distortion. However, you will notice that the result is wrong. Why this, is it due to the next step. I have computed the intrinsic, extrinsic coeffs and the rotation, translation matrices from stereoCalibrate(). Moreover I have extracted the R1,R2,P1,P2,Q matrices from the stereoRectify() (not sure if are needed):

According to the documentation initUndistortRectifyMap() should do that but my output is really strange as you can see:or something else?
while if I use the common undistort() function I am getting a better result:
distorted:Undistorted image (how I do not zoom in here??????????)
Undistorted:Redistorted image:
my other question here is can I get my undistorted Overlayed redistorted image without being zoomed in? and in to original (notice the surounding pixels being black. In general how do I align the rgb with the ir image and then apply the distortion again back (I guess the same procedure will be followed for the depth image).bad allignement):
