Is it possible to photograph a 360x180 panorama in one take?
My goal is to make a 360x180 panorama on the deck of a sailing boat (which obviously moves).
How can I do this?
Thanks,
Ron

The trick is to align the axis of the camera with a virtual centre point. That can only be done if the lenses are fixed to some of the platonic and or archemeadean spheres in which is guarantied that the middle of the sides is equidistant for the centre of platonic sphere and the centre normals of al its sides run through the centre of the sphere. A cube fits the bill with 6 lenses with a view of 170 degrees....that is used by the various supliers of GoPro based solutions. But when you look at these solutions they seem far from ideal since ideally the distance between the sensors and the centre of the cube should be as small as possible. Thus some parralax (a considerable parralax) remains and has to be calculated out by the Autopano Video software. The nice thing is that the nature of the parralax is known and known errors can be taken into account. But i've noticed that zoomin in using the sphere is not really consistent in quality (at least not in the Copacobana concert). Having said that, I must say it's a technology with a definite wow factor and great potential....I can even imagine a VR drama production happening if camera's can be smaller and better consealable in the set. Then you could see a scene from different viewpoints or cut a scene over different camera's. If cameras were as small as a pair of dice you could conceal them into a lampstandard or a chess figure. Just think about it.

and since they shoot 12 Mpixel each and use every one of those pixels is filled with image info I guess, qualitywise we would have a ty, depending on the camera used. A set of 3 D800 and 8mm Fisheyes could beat the GoPro setup in pixelcount (the P5000 files are about 20 Mpixel but the D80 is only 10 Mpixel since it is 10 Mpixel a 36 Mpixel camera would get to 36 to 50 (depending on the size of the lens circle, slightly larger lens circles would be best) Mpixel. The GoPro would be around 40 to 50 Mpixel....and remember 6 GoPro's set ou back about 2430 euro, about the cost of 1 D800....of course you'd have more dynamic range using the D800 but also much more pain in you're wallet.
P.S. i tried the stitching and it look nice enough.

Artisan New wrote:Aha, if GoPro's weren't invented someone should invent them for sure. But as far as the Mrotator it needs a circular FE which the Sigma is.
For a D800 a 8 mm would also be a circular FE.
But you'll need a circular (or close to circular FE). The D5200 + Sigma (or SamYang) 8 would also be great.

Artisan New wrote:Sorry Klaus that is incorrect....even Kolor says it has parralax issues: this is from the Kolor site:
Parallax errors can appear on close objects as the transitions between the videos are slanted in the middle of the scene. When inclined at 45°, the lenses are oriented horizontally. This REDUCES the parallax errors.

Russians are brilliant mathematics and great coders....I've worked with quite a few of them for different companies but they can't bend the rules of physics (only work around them). They only true way of having no parralax would be to take the lenses and shove them all in the NNP but that is physically impossible since they would eat up each others space.

3 x DSLRs with 8mm Sigma FE is viable too - as with the Agno's Mrotator-R:

You'll find samele image sets here if you want to try stitching them:

You definitely wouldn´t use such a rig in an action surrounding. THAT was what the OT asked for.
