MSL self portrait, Sols 84 - 85 Options

[EdTruthan]

Gotta say Mike, this is a stunning portrait of MSL and just beautifully conceived and captured. Many thanks to everyone involved for the brilliant sequencing. But oh boy, what bear to render. Figuring out the right projection so that no part of the image is too stretched is pretty tricky. And anaglyphing from 2 mosaics that always seem to render slightly differently and aligning them for minimal eye strain even more of a headache. Whew! There's a slew of things one could fidget with for weeks but... ready for prime-time or not, here's my initial version of the full resolution mosaic - anaglyphed (and links to the 2D, Sol 85 version below it). Admittedly, probably the toughest anaglyph I've ever attempted (...and still far from perfect...)

11/15/12 EDIT: All files have been now been updated and refined...
~ Shutter smear substantially reduced.
~ Horizon flattening refined.
~ Additional anaglyph dirt 'floaters' removed from both channels.
~ Additional anaglyph channel alignments.

11/16/12 EDIT: Added links for Sol 84/2D image to pair with Sol 85 2D for 3D imaging applications.

Yes, we've been having the same problems. Your version is really nice and definitely shows that you can get reasonable stereo out of the whole thing.

If anybody would find the metadata of use, let me know and I can probably provide it. We're just using hugin for this ourselves at this point and making no use of the metadata.

Also, removing the shutter smear would be nice. I'll see if I can post that as well if nobody beats me to it.

Yes - please provide us with the metadata for MAHLI and both MastCams if possible. Thanks.

I'm only talking about the MAHLI metadata for the self-portrait, and it'd be nice if you gave me some indication of how it would help processing. I've already discussed my inability to release metadata in general; it will be included with the PDS archive.

[iMPREPREX]

Well, I apologize - I just wanted the data so I could plug it in to the stitching programs (I am a beginner), and there is a lot on this site to sift through. I apologize for wasting your time. Just wanted to help.

My contribution to this truely awesome piece of work. Tooks me the entire afternoon in order to export the JPEG output. It's very LARGE !



And the Flash VR version of it, available here :

Ed Truthan: I will download your files, but by judging the thumbnail, you did a great job . I suppose that it was hard for your computer too .

[TheAnt]

Thank you for posting the "self portrait", amazing sight.

[Ant103]

I see that somebody has edited my post. Yes, I did confound Astro0 and Ed. Sorry for that…

So, Ed, truely great piece of work, it's easy to view the stereo effect all around the panorama. For me this will be one of the Image of this end of year from Curiosity.

The metadata for pointing is in the form of the CAVHOR model vectors (see, e.g., http://www.agu.org/pubs/crossref/2004/2003JE002199.shtml ). Hugin at least requires pointing information in the form of roll/pitch/yaw. If anybody already has code to go from one to the other, or knows of mosaicking software that uses different types of pointing information, please let me know.

I'm going to have to jump through some hoops to get permission to post this, and I don't want to bother if nobody can really do anything with the data.

[Ant103]

Yes, roll/pitch/yaw could be the best option. And this will be very usefull in order to build a good mosaic of the sky, where control points are useless there.

[mhoward]

I can deal with CAHVOR to some extent (still working on it). It would be a goldmine for me just to see an example of what the metadata looks like.

[EdTruthan]

For those who are interested, I've added some refinements to all sizes of both the 2D and 3D MSL Self-Portrait files from my above post in this thread. Changes are listed at the bottom of the original post.

And Mike, thanks for the CAVHOR meta data offer... like others above have mentioned it'd be really interesting to give it a gander but since I probably won't have time to re-visit the MSL Portrait again soon I can't confirm a personal need at this time. Your kindly offer is acknowledged though. I'm sure in the long life of this mission there will be particular mosaics which may be extremely problematic or even impossible without meta-data so your willingness to hoop-jump to connect us with it is very much appreciated. Thanks indeed.

Wow, beautiful job aligning the 84/85 portraits, Ed!

Any chance, if you've got the server space, that you could post the corresponding sol 84 mosaic? It would be insanely cool to view in full colour stereo on a 3D display...

[mcaplinger]

Wow, beautiful job aligning the 84/85 portraits, Ed!

Definitely a great job, and better than anything we've been able to come up with.

Did you use hugin? If so, might you consider posting the files? I like the registration a lot but I think I could improve on the image cosmetics.

[mcaplinger]

BTW, this is obviously off-topic but I've been asked to point out that we've got a software engineering position open at MSSS -- see http://www.msss.com/about-us/jobs.php for details.
