Re: [hugin-ptx] Re: Lens correction with Hugin

I'm really comfortable making corrections with horizontal lines. Based on Torsten's tutorial I translated to the new version of Hugin and where the image jumps after you make a control point. In a horizontal image you just know that you can click on both sides of the image just at the inside edges

Re: [hugin-ptx] Re: Lens correction with Hugin

I was asking that if I had to also use vertical lines, how would I line them up on top of each other like two portrait orientation images and match a vertical line top to bottom. Since I don't have to use vertical lines and can use only horizontal lines then it's a moot question. I just wasn't

[hugin-ptx] Re: Lens correction with Hugin

Just to make sure I understand correctly, you don't need to do both vertical and horizontal lines to create a proper lens distortion correction. You only need to use horizontal linesright? And if you do need to do vertical lines, how would you line them up in Hugin since they wouldn't be

Re: [hugin-ptx] Re: Lens correction with Hugin

Thank you very much. I was working toward what seems an impossible end. Disregarding the difference in the numbers, I was finally able to arrive at the proper corrections for the 16 and 20mm focal lengths for the zoom lens I'm testing. Thank you very much for your help and kindness. Best regards,

[hugin-ptx] Re: Lens correction with Hugin

Thanks for the reply. I redid everything making sure I added a new line 3, 4, and 5 for the lines I was using. I've included a video of the process after I added the lines. I'll show that each line is it's own number yet when I optimize them all the numbers I arrive at are vastly different than
