On Kodak introduces PixPro SP360 action cam article (62 comments in total)

here is an example 360°x180° full sphere equirectangular video stitched from 2 SP360 (214° fisheye lens) video clips from one camera rotated 180° for each shot, moving objects disappear along the seam but shooting with 2 cameras back to back would resolve this, parallax would probably be ok at about 3-6 feet -

In reply to:

Sam Rohn: ricoh already has a one shot camera that produces 360°x180° full spherical panoramas available for sale since october 2013, the ricoh theta

https://theta360.com

overall, ricoh theta has better image quality than panono samples, panono seems to have very bad color rendition and an odd "honeycomb" vignetting pattern caused by the array of cheap lenses, theta is also smaller, lighter, and about half the panono's estimated price

spherical and non-spherical panoramas are described by FOV width° x height°, just like any other image

so if your non-spherical panorama shows an area 180° wide by 60° tall it would be described as such, for example a 180°x60° cylindrical projection etc, this would also equal a 3x1 aspect ratio, but aspect ratio is not the sam as FOV

in any event, 360°x180° is the proper and accepted term for spherical panoramas among those in the pano industry, 360°x360° is just confusing to those familiar with this sort of thing, better to use accepted standards ;)

see these links for more info on FOV and image projections, note the equirectangular projection which is considered the standard projection for spherical panos which are displayed interactively on sites like panono, 360cites, google street view, etc

thanks jonas

definitely better colors on the panono eiffel tower pano than some others i had seen although i have seen sharper theta panos than that example too, looking forward to seeing some newer panono images from a production unit :)

theta can also show similar artifacts w dark vignetting seam areas and odd flare/glare from sun etc, in my experience this is caused by position of sun or other bright light relative the the lens, normally one would flag out the sun etc but this would not be practical for one shot cameras i suppose

also, spherical panoramas are properly described as 360°x180°, not 360°x360° as in panono description

360° around the equator and 180° pole to pole, this also describes the equirectangular projection which is commonly used for such images - http://wiki.panotools.org/Equirectangular_Projection

other projections might have different dimensions, theoretically you could make a stereographic little planet at 360x360 if you so desired - http://wiki.panotools.org/Projections
