Astronomy Picture of the Day -- Apollo 17 VIP Site Anaglyph
NASA ^ | March 15, 2014 | (see photo credit)

Posted on 03/14/2014 9:29:12 PM PDT by SunkenCiv

Explanation: Get out your red/blue glasses and check out this stereo scene from Taurus-Littrow valley on the Moon! The color anaglyph features a detailed 3D view of Apollo 17's Lunar Rover in the foreground -- behind it lies the Lunar Module and distant lunar hills. Because the world was going to be able to watch the Lunar Module's ascent stage liftoff via the rover's TV camera, this parking place was also known as the VIP Site. In December of 1972, Apollo 17 astronauts Eugene Cernan and Harrison Schmitt spent about 75 hours on the Moon, while colleague Ronald Evans orbited overhead. The crew returned with 110 kilograms of rock and soil samples, more than from any of the other lunar landing sites. Cernan and Schmitt are still the last to walk (or drive) on the Moon.

That buggy should be worth a lot of money by now. Old enough to be a classic, and very low miles. (May need a new battery.)

Why, I've got them right here!

But you know, there's something funky about the LM, wrt the anaglyph that is. What's up with that?

Yeah, I can’t get a good stereo view of the LM. The red image seems to be displaced too much. The Rover looks great though.

Maybe an artifact of too much camera jiggling.

I think this was made from two separately taken snapshots.

I suppose the image pair of the anaglyph was not ideal, being composed of images with differing distance as well as lateral position, and that the anaglyph was optimized in some sense for the rover, which looks real good.

Not sure how all that works out though.

saved for when I find my red and blue lens 3D glasses (weirdly enough I went to a 3D movie tonight and left my glasses, but my son kept his pair).

Wouldn’t it be funny if we return to the moon in 10 to 15 years, revisit the site and find the wheels gone and the lunar buggy sitting up on blocks.

Anyone have an idea where I can get 3D glasses short of stealing them from a theatre?

I always prefer that on the computer they don’t make these 1950’s 3D movie glasses type viewing... but traditional stereoscopic twin imagages... that way I can cross my eyes and see it in full 3D magnificence w/o glasses.

Funk was big in 1972.

The component pictures seem to be AS17-143-21932 and AS17-143-21933

I’ve made anaglyphs myself. Of course you need two pictures, taken from a slightly different location but at the same angle. You convert one to red and the other to cyan and merge them. It’s tricky to get it just right though.

Here's an anaglyph I made from the two Apollo images using "Anamaker", a free online download that I got a few months ago. Works real nice. I used Paint.net ( also a free download that I've had for some time ) to rotate and align one of the images with the other along the horizon. Only took a few minutes.

It came out small, but it looks pretty good. It seems a little crisper than the APOD, if I do say so myself!

The LM looks cleaner, for one thing ...

It’s very nice, yes. This, by the way, is why it’s so much harder to find programming jobs these days. Software companies have taken over and provide at a far lower price the sort of stuff you’d have to hire a programmer to do in the past. Of course software companies employ programmers, but another reason is that the technology changes so fast you need a Maserati to keep up, and I’m a used Ford Chevy.

Well I realized it was small because I was using reduced images ( duh! ) so I got the good ones and redid the anaglyph, and I think this one is definitely better than the APOD:

If you look around the frontmost tire ( without the glasses ) you can see the difference. Also note the "microphone" looking thing at center shows no displacement in the APOD, placing it at "infinity". I'm thinking they used some kind of fancy canned software which didn't quite do the right thing.

As shown below, I think I can accurately reproduce the APOD by simply lining up the images to match the position of the low gain antenna, which looks like a microphone. Note the LM looks just the same, in particular.

The one difference is along the horizon, where I got a thick red strip on the left side, but Aha! Look at the APOD horizon behind the high gain antenna ( i.e. looking through it ) and you will see the red strip matching mine. So I think they just edited this out, where possible. Note the blue strip on the right horizon is still there, and matches mine.

I think they decided to do it this way because the image shift is too extreme with the horizon match method. Even so, the APOD rover anaglyph is still kind of strange because the position shift is mostly in the vertical direction. It still seems to work though!

There does seem to be some shift in the vertical, and no doubt NASA did some post-editing. The #20 post seems the clearest to me, with the sharpest background and the rover seeming to jump in your face. One problem that cannot be fixed, not easily anyway, is that all color monitors are a little bit different, and this one doesn’t exactly match my red-cyan glasses. But perfection is an impossibly lofty dream...
