Hey everyone,

I've been trying for weeks to get a good calibration running and I've read through the forums about how to get a good setup. I think i'm close, but I have no idea what is causing this type of distortion on my undistored images.

I used 13 images in this example and I've tried using more, but the red box just goes farther away and the noise around the red box grows. Below are the results of the output:

Is the only solution to take pictures of the checkerboard on the edges of the frames? I've tried that and it doesn't produce a better result.
