Unmanned Spaceflight.com _ Image Processing Techniques _ Unbending MER Hazcam Images

Posted by: PDP8E Jul 15 2009, 02:20 AM

I have seen hazcam images somewhere in these forums that were 'straightened out' (unbent?).
I have searched for 30 minutes now and cant find them.
My question to all of you resourceful image-smiths is...what is the recipe, procedure, or tool ... for unbending the hazcam images?

thanks in advance.

cheers

I haven't de-fisheyed any Hazcam images, but I did un-fisheye the Huygens landing images using PT Lens Photoshop add-on and was really pleased with the results.

(Props to stevenv2 for the suggestion to use PT Lens.)

Here is the site for the PT Lens download: http://epaperpress.com/ptlens/

Mike,

That's a great little tool.
I downloaded it and tried it out...and it de-fish-eyed as promised.
The price is good too ($25 USD).
Just bought it.

Thanks!

With a classical panoramic stitching software, like Hugin, you can de-fish-eyed the pictures.
I.eg as a equirectangular view and put it in a QTVR :

Ant,
that is unreal -- thanks for pointing me into another interesting direction!

That's really nice Ant, I like that viewpoint a lot.
