Mars 3D via ImageMagick - Cont'd

For fun, here is another Homebrew Mars Cross Eye Photo created with the following ImageMagick command on linux (see previous post). Original photos taken on Sol2 via the Navigation Cameras.

Sol0002 - Cross Eye 3D Fake Color

I think you can see two blast craters created by two of the four decent rockets. Assuming that they are blast craters, it would be interesting to know the direction the Sky Crane left the area, the blast pattern might suggest to the left or to the right.

The following are my observations, and therefore obviously not authoritative.

What is not obvious in the original photos, and which can only be seen in the 3D view, is a slight depressions (running left and right) beyond the large lumps (about 1/4 down from the top). Also, there appears to be a old yet small crater near the same lumps, and nearer than the depression. In the distance, the ground appears to be much less level, Curiosity's Sky Crane picked a good level landing spot !

A 3D view provides so much more insight !!

Because of the distance between cameras (much more than the normal width between your eyes), very close items is in the foreground are hard to view. When (if) the camera is aimed a little higher (at the horizon), there would not be the very near foreground distractions.

This Cross Eye 3D viewing technique is not for everyone, some people complain that it gives them headaches. I have now trained my eyes to automatically adjust as necessary, and can quickly enjoy the images. It helps if you tilt your head so that the horizon (as it appears in the above image) is horizontal (as it should be).

UPDATE:

Here is a later interesting Image, only in the 3D view is it obvious that the large foreground rock is stacked on top of another.

Mars 3D via ImageMagick

With a little ImageMagick it is easy to create a "Cross Eye 3D" image for viewing. Mars Images have names like:

FLA_397506083EDR_F0010008AUT_04096M_.JPG

FRA_397506083EDR_F0010008AUT_04096M_.JPG

Note: The second Letter denotes which camera (L or R) took the photo.

The raw file can be downloaded at:

http://mars.jpl.nasa.gov/msl/multimedia/raw/

To create you own 3D images:

• Download the Largest Left and Right images for a scene from the NASA web site.
• Execute the following ImageMagick command (of course, substitute the real Right and Left file names). 

convert  R.jpg L.jpg  -splice 10x0 +append -chop 10x0   3d.jpg 

• Display the resulting image, adjust the display size to fit your screen.
• Use the "Cross Eyed 3D" viewing technique.

Homebrew Cross Eyed 3D Image Viewing

The white space between the Right and Left images, helps your mind to concentrate on only the center phantom 3D image produced with this technique.

Note: Some people have difficulty with this 3D viewing technique. But it is as easy as looking at the tip of your finger at about six inches from your noise, while gazing beyond, at the displayed image on the screen. When it works, you will see third image, in focus, between the two originals on the screen. It may take a while to train you mind to accept the 3D image.

Note: Unlike triditional 3D Stereoscope images "Cross Eye 3D" images must be arranged; Right image on the Left, and Left image on the Right, so that each eye when crossed, will see the correct image.

Note: Normal two color 3D images could probably be created with ImageMagick, but I need to learn a few more Magick Tricks to provide details.

It is Fun, Easy, Quick, and you may notice something in the new Mars Images before anyone else does !!

Try it with the thumbnail image provided on this page, place your finger tip about 1/2 the distance to the screen (your focal point) and slightly under the center of the combined screen image. And/or, click on the image and try it on a larger image.

UPDATE:

Maybe something like this will work with normal colored 3D glasses, unfortunately I do NOT have a pair to try.

convert R.jpg L.jpg -fill blue -tint 200 -fill red -tint 200 -combine   3DColor.jpg

Color 3D??

Or, try this:

convert R.jpg L.jpg -adaptive-sharpen 10 -fill green -tint 200 -fill red -tint 200 -combine   3DColorGn.jpg

Try This

UPDATE:

Here is what is hidden inside of the NASA Very Dark Rear Camera Image:

I think the top of the wheel joint can be seen at mid-right of the image.
