  • Camera Matrix - Distorted vs. Undistorted Image

Hello!

I have a quick question about the calibration script used for the OAK cameras, as well as some gaps in my CV knowledge.

I am using a few IMX577 sensors with M12 lenses attached to a robot to measure points in the images. I need to use the camera matrix combined with my extrinsic parameters of the camera modules to accurately measure these points with respect to my robot.

What I am confused about is the relationship of the distortion parameters and intrinsic matrix. I have read that undistorting the image with the distortion parameters does not change the intrinsic matrix, but wouldn't this shift where the points are in my image, leading to a different result?

Is the intrinsic matrix we get from the calibration script valid for images that have been undistorted with the distortion parameters from the calibration?
