BTW, as far as I know we have no immediate plans for a 3D release, so you guys can go nuts with that.

... All that said, the rover body came out pretty white so I don't think the color is too far off. I'd have worried more about that if we had more time, but it took a while to get all the tiepoints right. ... I would love to see you and your colleagues' attempts at revealing the true colors of Gale as you characterize the cameras and integrate the global lighting effects as you've analyzed them. If that is one of your interests with the data, please let us know if ever such an image (or images) is (are) released. It is remarkable to get your perspective on this mission as you and your colleagues do the work. Thanks for sharing it! |

Truly awesome self-portrait, which really helps to identify various components seen in previous shots. Remember the odd scratch marks seen on NavcamR images for Sol 62? On this Sol 84 MAHLI frame, the marks can be seen again, on a suspension strut attached to the right front wheel. Detail crop, tweaked and flipped to approximate the Sol 62 image:

And there is something we can't see immediately, but what panoramic stitchers like us know, is that there is absoluteluy no paralax between images. This lead me to this conclusion : the robotic arm had to do complex gestures in order to avoid shiftings, rotating itself around the optical center of the MAHLI lens. I'm not a stitcher, but I did notice this. There's quite a bit of overlap between frames, so I checked to see if I could make a stereo view of the RSM using neighbouring frames. If mahli had rotated about some axis on the arm, you'd expect transverse displacement (leading to parallax) as the pointing changed, which would let you make an anaglyph of the overlapping regions.But when I tried it, I saw that there was very little transverse movement (and what was there was totally dominated by lens distortions). So, like Ant says, it looks like effort was made to rotate about the optical centre. That gives me hope that the 84/85 stereo view will be very clean (at least for the appropriate projection). Edit: the full resolution almost-simultaneous ML view of the turret is down! |

It would be fascinating to see that in anaglyph too (beg beg). I'd expect various 'imposible' 3D effects to pop out. Here you go. -------------------- If Occam had heard my theory, things would be very different now.

That's excellent Jam Butty! There's such a lot going on there with the turret movement and two very different sets of reflections also moving between frames. It would be fascinating to see that in anaglyph too (beg beg). I'd expect various 'imposible' 3D effects to pop out. Here is a zoomed and croped anaglyph of the mirror, but as Ant and fredk have pointed out, there is not a lot of parralax between these images. Most of the displacement that can be seen is probably due to arm/turret movement... |

Oh my oh my oh my that's nice.
One general comment, not just to you but to everyone doing image processing work: I suggest processing out the "schmutz" on each camera. Mastcam-R has one prominent black schmutz spot (see this pic). MAHLI has 3 or 4 big ones and several smaller ones (they are easy to see in this photo that mostly contains sky). They're especially distracting in stereo images. If you're going to spend hours and hours building and blending seamless mosaics, dust 'em off a bit first! ADMIN NOTE: A few later posts about the "schmutz" moved here. See Ed's clever Photoshop 'Action' for removing it. -------------------- My website - My Patreon - @elakdawalla on Twitter - Please support unmannedspaceflight.com by donating here.

I've updated the self-portrait pan with two of the three missing frames. Just one missing and it will be done, I think
And my definitive postcard version of this mosaic. Fredk : very good stereoscopic view. I hope finding the time to do one with the whole mosaic of the next sol. -------------------- |

That postcard version is my favourite of the mosaics so far from any source. Why? Because you have rendered the horizon - horizontally. I can only feel I'm there (and focus on the foreground) once that's done right. The official version has it sloping and most others have it curved.
As a bonus it has "Dumgoyne" dead centre. |

Yeah that's a great version too.
Jam Butty and EGD - thanks for posting those ChemCam anaglyphs - I overlooked them last night. Looking without glasses I notice the red and cyan fringes are opposite ways round in the two versions. In each case peculiar things happen to the reflections and the moving turret when viewed with glasses, and as this is only playing around it's fun to have both. |
