We can't be smarter than fifth graders if we don't learn how to web-search. What's up now Foxworthy!?

Results 1 - 10 of about 13,900 for Mars rover cameras diagram

For such an extremely wide field, conventional distortion correction is impossible. Instead, equalmeridional angle increments in the object scene are mapped (ideally) as equal linear increments on the image plane. When looking at the whole scene, a fisheye lens unavoidably produces a great amount of barrel distortion. This distortion is actually just the consequence of projecting a hemisphere onto a plane. Of course, the mapping function can be calibrated. Of more practical importance, small parts of the scene, even those near the field edge, are imaged quite accurately without needing a lot of subsequent image processing. But the horizon in most
pictures appears strongly curved. ...

Re: Weird Mars Rover Spirit Image

It is an illusion. It is part of the rover and I can prove it!

Erhmm...yes; I think we all agree the object at the top is part of the rover. The HazCams are mounted under the body afterall.

Scroll to page 6 at this link to see a diagram showing the camera locations. The overhangs above the HazCams are clearly visisble.

YES! You figured it out before I did.

These pix were taken by the Hazard cameras which are mounted very low next to the front wheels. (So, they can see what is blocking the wheels. Duh!)

What you see across the top, like a bank of snow with buildings and strange rocks in the distance, is actually the UNDERSIDE of the solar panels!!! It is dark. The "snow" is actually a strip of sky between the underside of the panels and the real horizon.

The "building" is some kind of vent structure on the underside of the panels.

A likely story! But correct.

I am for once at a loss for words, if that is a real image and it's not just a trick of perspective then the whole world as we know it changes doesn't it?
