Opportunity 2454 - navcam photojournal.jpl.nasa.gov/catalog/PIA13756This 360-degree mosaic of images from the navigation camera on NASA's Mars Exploration Rover Opportunity shows the view from the western rim of "Santa Maria" crater on the the 2,454th Martian day, or sol, of Opportunity's work on Mars (Dec. 19, 2010). South is at the center, north at both ends.

Of course, this leaves the totem right in the middle with bad data right beside it at the point of overlap. So, in the 3d image we have a weird effect - the software they are using to combine the data doesn't know how to handle this bad data - making it look like those rocks are closer to us, rather than on the crater wall with the rest of the rocks.
Now - check this out.
If any of us were going to produce a panoramic image here on earth, how would we do it?
We'd want nice smooth matches, so we'd mount our camera on a tripod, then move only in a panning motion from right to left (or left to right). We would not change the tilt of the camera - because if we did, re-combining the separate images would be a nightmare.
Take another look at what JPL did.
They tilted the camera as they panned (or they lowered or raised the boom on which the camera was mounted)!
We know this because the bottoms and tops don't line up - and this creates all the mismatches when you try and stitch the images together!

These pans are programmed in advance - the rover is not doing this on its own.
So, why did JPL tilt the camera instead of making simple straight pans?
Was it insanity or incompetence?
I hardly think so.
Take a look again at the great amount of space in the overlap zone - marked in yellow.
These areas yield double the data as a result of the camera tilt. By tilting - it is like zooming in on the overlap areas with a zoom lens. How? NASA-Ames developed super resolution software that takes data from multiple perspectives and recombines the data - as long as the data is acquired from different angles. So, in the overlap areas - we have FOUR different angles of view to be combined into higher resolution.
We have the left image - the right image -the overlap left image taken at a different tilt - and the overlap right image taken at a different tilt.
So - in overlap areas - with the Ames software - not available to the rest of us - NASA can zoom in for a much closer view!
This means anytime JPL wants a zoomed view of a spot in the distance that the rest of us can't have, they simply have to make sure that their target falls in an overlap zone!

Now that we understand what can be done with an overlap zone, consider this: In any pan they take, nearly one-third of the total area in the field of view is in an overlap zone:

Haha, very cool. A very insightful analysis, showing that we possibly see only "filtered" images. Thumbs up. "There is more than meets the eye" 8-)

Thanks, convex. Yes - it appears their software can plug those pixels into 3d spatial data sets - and produce various views of any scene where they have taken enough images. I may check this software below out later and see what it does: vrmars.com/

ONG..this is so cool! AND how ''strange'' that the picture is missmatched right there to! ....BUSTEEEEED!!!
i LOVE this kind of stuff! I wish i cound go there and see it myself!! :)))
