I'm using the camera corrector application to correct a series of images that have barrel distortion using chessboards. Following the steps below:
1.I attach the series of photos to be corrected with the different positions of the chessboard, without modifying the position of the camera.
I introduce the size of the different squares that make up the board. And frame that has a high distortion the image to process enter image description here
I perform the processing of the different photos and press the calibration button enter image description here
Detect the different points of the chessboard enter image description here
And I hit the "show undistorted" button. To see the result of the correction. enter image description here
Apparently the image is corrected. But using a photo correction program, I observed that this is not the case, that there are errors in its correction. enter image description here
it is observed that the upper right corner is not fully corrected. I have carried out the same procedure with a smaller number of photos, with a different location of the chessboard, etc. I am somewhat confused. What could I do to completely correct the image? enter image description here
