My first semi-successful attempt at a stereo mosaic, four pancam shots from
each camera, taken by Spirit on Sol 050. As always, my relative alignment,
rotation and scaling of images is entirely subjective and thus this image
has little or no science or engineering value. But it looks pretty spiffy,
if you don't look far beyond the center.
Notes on Anaglyph images
You'll need red/blue 3D glasses (red lens over left eye, blue lens
over right eye) and reasonably good
vision in both eyes to get the full effect. Cardboard 3D glasses with
plastic lenses are cheap and widely available, including a number of
online retailers. Just search
Google (or better yet http://www.froogle.com)
for "3D anaglyph glasses" and go shopping. You may already have a pair around
the house if you went to see "Spy Kids 3D", or bought the 3D Sports
Illustrated Swimsuit Edition
a couple of years ago.
These are derived from
the raw images on the
NASA/JPL mars rover program web site.
I have endeavored to feature scenes which have not been featured
in anaglyph form in the official NASA/JPL press releases.
Please note that I have
manually adjusted the registration of the stereo
image pairs, so these anaglyphs are not appropriate for rangefinding or
determining the true size and shape of objects on Mars. Also please
note that all of the stereo camera pairs on the rovers are
"hyper-stereo", which means that the horizontal parallax is greatly
eggagerated due to the camera lenses being spaced much further
apart than human eyes are. Thus the subjective perception of depth
and size, especially absent of any common objects to provide relative
scale, is going to be very misleading (but pretty cool-looking).
Objects nearest in some scenes are often prone to be over-displaced and
may appear as double images even through the 3D glasses.
Many more Mars Exploration Rover anaglyphs are coming very soon, along
with proper captioning of rover, sol and time for all of them.
Enjoy!
