Barrel Distortion Correction

hello,i would like to know if anybody could tell me an algorithm for barrel distortion correction. I need to gather positional data of objects from an image and therefore i need the image to be accurate. Any help would be greatly appreciated.cheers

Maybe you could've mentioned that in your original post. Now it looks like it's just another post of a lazy student looking for someone to do his/her homework.

Ok: Structure-from-Motion (SFM) algorithm.

An other term for barrel distortion is radial distortion; you might want to Google for that as well.

Good luck.

PS. If you cross-post a question, please refer to the first post in your cross-posted one. Now people might answer you here while you already got an answer elsewhere.

Cheers for your help i'll look into it. As it happens I am a student but i don't like the lazy tag. Maybe a bit dense but not lazy.

This is my first post (originally in Java 2D forum) and when i realised there was an algorithm section i thought that was a better place to make my post. (is there a way to change the forum your thread is in after posting it) But thanks for the advice i'll keep it in mind.

Anyway thanks again

No, you don't seem to be lazy (and I honestly didn't mean to imply it!). About the student and dense part: there's a close resemblance with me ; )

No you can't change or delete a thread. It's a bit of a forum etiquette to post a link to the other thread; in that case people who answer know if an answer has already been posted or not.

You're welcome. Do post again if you run into problems.

Regards,

Bart.
