- Ensure Accurate Calibration: Use a wide range of high-quality calibration images that cover the camera's entire field of view.
- Choose Interpolation Wisely: Experiment with different interpolation methods during the undistortion process to see which minimizes artifacts.
- Crop Edges: If artifacts are mostly around the edges, consider cropping the undistorted image to remove distorted areas.
- Update Software: Use the latest version of your calibration software, as updates may include improved algorithms.
Undistort image and camera calibration app

I am using the camera calibration app to measure camera parameters, and correct for radial distortion (3rd coefficients), skew and tangential distortion. However, the undistorted image that I obtained has a weird patters around it. I attached an example image. Why is this effect introduced? How can I correct for it?

The artifacts you're observing in the undistorted images are likely due to the correction of significant lens distortion, inaccuracies in the calibration process, or the interpolation method used during undistortion. To minimize these effects:
Improving calibration accuracy and adjusting the undistortion process are key steps to reducing these artifacts.
