sol 1387 L456/R1234567:



with link to 1398 Navcam view.

It is not unreasonable to infer that the dark areas in the Navcam view is similar to the dark areas in the pancam view.

Er, what's with that dark circular patch at the base of the red color chip? There is a hint of a similar dark circle below the green chip too.

Note also that the dust on the sundial and magnet appears to be the fine "red" dust from the storm. The dark dust -- especially the really dark dust near the color chips -- is what and from where?

I created the rover image using this Interactive 3D Rover model by eyeballing the orientation I wanted, did a print screen, pasted the image to Paint, saved and then loaded it into imagej, converted to B&W, did a polygonal select, copied, positioned and pasted the selected image to the base image.

It would be nice if the interface had a numerical input option to select lens, distance and orientation. Then a "real" 3D SFX image could be created.

And, yes, the best way to maneuver Spirit is sideways, but what would be the best orientation for maximum sunlight? My guess shows the mast shadow fall mostly on the front of the vehicle.

This is my best guess. Spirit will back down the slope? Maybe stop a little higher up the slope to get more tilt?

I'm sure the SFX gurus ( guruae?) can create a better image, but I thought I would try -- since, as Tesheiner pointed out, there was no movement tosol.

sol 1389 ( Nov 30, 2007 ):



Perhaps the north facing slopes in this little western cove are steep enough for a winter's stay?

Not frost.

I am suggesting that the sol 1346 image may be frost:




The 1347 image was taken at 14:42 when the sun was at 51 degrees. I made the simplifying assumptions that Cabo Frio was due south and that the sun was due west, so anything on a slope greater than 49 degrees would be in shadow.

I didn't actually measure the slopes but I asked asked Buzz and he thought the slopes were greater than that.

It is possible that the bright areas are just weird sidelighting.


Anyway, thought it would would be interesting to post the speculation.

Frost?

You must view the original size to see the animation.

sol 1358 colorized "super resolution":




I'm always looking for new ways to combine the MER images.

This one has the brightness channel of a synthetic color L2/L6 image replaced with the sharpened average of 16 "super resolution" frames after a 2X scaling and translation allignment.

Useful to the rock guys?

Thought some might be interested in a color version of the superres pan.


And here is a "work in progress" sol 1337 L257 pan looking down at "Smith" ( I think):




I have just about given up on Oppy panoramas. Does anyone know what happened to the "plan" to release the "RAW" JPGs with a dust correction?

Bravo!

Er, could you share your flat-field dust masks? I have "hit the wall" trying to use the pancam sky-flat images to correct for the dust. I have been using the L1 filter to correct the image after RGB conversion.

Here is my final attempt at the north view:

sol 1334 position:



I haven't done one of these in a while -- but thought I would try my hand again while Tesheiner is travelling.

If it is correct ( I have bene known to be wrong about these things ), it looks like Spirit is headed for an exit ramp -- but was facing the "wrong way" in the last rear hazcam view?

Oppy sol 1294 L257 2x3 panorama:



Lots of synthesized missing data. I applied a variation of the Ant103 dust mask as a division by the inverted mask plus an offset.

I am ready to give up developing a simple "ACME dust correction" (beep, beep.)

Please, please JPL, apply the dust correction before creating the "raw" JPG images!

Er, the red spots are most likely imaging artifacts caused by interpolation and registration of a tiny piece of a pancam image with a MI panorama.

But there is a small quantum mechanical like probability that it is chili pepper flakes -- freeze dried.

The image colors are only a hint of what might be.

An experimental MI dust correction was applied to the images before autostitching the panorama.

sol 1291 L257 1x4:



Without at least a 1/3 overlap I don't think a dust compensation flat field mask will work on the 8 bit JPG data.

I hope that the Cornell Pancam Images will have a dust correction.

sol 1291 R0 1x3:




L0 1x3 here


All the images have sky-flat dusty lens corrections.

Spirit - Opportunity MI lens comparison animation:



The fuzziness of Oppy's miniTES mirror reflection may be mostly from the dust on the MI lens.

In general, all of Oppy's optics appear dustier than Spirit's -- so it would not be a surprise Oppy's mini-TES optics are dusty too.

Here is a comparison animation of the IDDs. Although lighting differences account for some of the differences, most seem to be directly dust related.

Spirit / Oppy miniTES mirror comparison:



Although the mirror seems to be working -- the reflection from Oppy's mirror seems less distinct --
so there may be "only" a dust problem and not a mechanical one.

You are correct fredk.

If you look at the two sequences side by side -- and if the glare is ignored --
they are similar.

animation of Oppy sol 1288 mini-TES mirror test:





Uh oh.

The port opened and closed -- but the mirror images look different than in the same test done by Spirit.

( see links in the image comments.)

sol 1285 R0 1x3:



The images in this pan have an experimental navcam sky-flat lens correction. It actually worked out better than I thought.

There are image links to a navcam 3D and an L2 pancam montage with similar lens corrections.

Oppy sol 1281 L257 1x4 of Duck Bay:




Not sure if anyone is interested in this, but thought I would share...

The pancam images have been processed by using the L2 L7 SkyFlat images as masks to compensate for the lens dust. Also, a square root filter was applied to the images after dusty lens processing.

There are links from the panorama to individual 3D images.
