I had to use a calibration chart, but it is interactive so you can change the line detection parameters. Once you get a good image with sharp lines it is very accurate, and it will show you what the transform is, IE you can see your crooked lines flatten out.
For what its worth, I tried the light room lens calibrator also. It is very sensitive to less than ideal input images, I wish there was a way to use that data directly for lensfun. It was nice because the input image was a chart that was printed, so it knew where the corners were supposed to be.
