Hi,
I am following off of a distortion model calibration as shown in this video
https://www.youtube.com/watch?v=RxmUgSKT0pg
However when I replicate the steps I am not getting valid images on my front panel. The corrected image is all blurry. What is the reason and is there a way to rectify this?
Another question : Is it necessary that during calibration the grid covers the entire field of view?
cal2 is my calibrated image
rawimage4 is my snapped image

Hi Vishwarath,
Try the following tutorial:

My understanding is that yes, the grid has to cover the entire field of view.

Hi George,
My FOV is quite large. Do I zoom the image and crop it so that only the grid remains in view? In the video you suggested did the camera already focus on the grid leaving everything aside

Hi Hatef,
What is the camera is grabbing some more regions than only the grid?

I think that if you crop the image it should be OK.
You have the make sure that the second image you calibrating is exactly the same size in the same location.

So I have the following workspace which I need to calibrate. I placed the grids adjoining one another. How should I go about doing this?
