Panoramic Image Stitcher Application for N900
I am not sure how hard this would be, but with the N900 having a "quality" 5 MP Carl Zeiss camera, is there any developer interested in tackling a challenge on making a Panoramic image stitcher? Something that would take a series of photos, like up to 10, using a transparent, overlaid edge to line up the next shot with the previous one, then stitch them together to form a large panoramic image. I would imagine in would work in conjunction with the camera application somehow, so all the image parameter would be set up that way e.g., image size, quality, effects, etc. It could be really cool. Any one out there working on such a program, or be willing to?

Re: Panoramic Image Stitcher Application for N900
Yep it's an interesting topic. Might be better to find some existing software and re-compile that rather than re-writing (though writing it yourself is of course the interesting bit). I'd search for a command link app ideally (no gui = fewer deps and the possibility to integrate it into some other program more easily).
I've just done a quick Google and these things exist, in fact quite a few do, and many are command line apps (as this is a reasonably popular research topic, so there's lots of codes out there) |
Re: Panoramic Image Stitcher Application for N900
Yeah - recompile hugin I reckon.
Gui based, but gtk so all is well there, then panotools for the backend. This of course is easy to say! |
Re: Panoramic Image Stitcher Application for N900
On my S60 phone, the camera application does this. You take one pictuture after the other, and they'll all get saved as one large panorama image.
Are we sure yet that the Maemo 5 camera application will not offer this feature? Of course hugin or thelike would still be nice for images that come from a different source then.... |
Re: Panoramic Image Stitcher Application for N900
No panoramic feature in the N900 camera application. (In general, there are zero to minimal links to any S60 application vs. 'respective' Maemo application.)
But it's definitely a cool idea, especially considering that the N900 takes some nice photos. |
Re: Panoramic Image Stitcher Application for N900
thx for this info, ragnar.
hugin, iirc, has a terrible UI. and i'm not talking about "all thumbs" - it's hard to use on the desktop, too. simply too powerful, too many options. it's not fun. not at all. maybe a dramatically simplified GUI based on the same backend would be better, even if you lose features and settings. |
Re: Panoramic Image Stitcher Application for N900
Yes, definitely keeping it simple. iPhone has several of these kind of apps - useful for inspiration and reference.
Pano: http://debaclesoftware.com/ TripStitch: http://byteslice.com/Support/TripStitch AutoStitch: http://www.technosanity.com/2009/06/...-panorama-app/ It would really need to be as simple as those are... |
Re: Panoramic Image Stitcher Application for N900
still, the easiest way for any user to create panorama images is directly from the camera: take a picture, move the cam to the left, take a second picture etc etc.
this process could be further simplified if the cam application takes a new picture without any user interaction as soon as the overlapping area reaches a certain minimum. (i think this is how it's done on my phone, but i cant recall exactly - it's 2 months since i last used it.) this needn't be included in the stock camera application. it would be OK as a standalone app. BTW: this is probably the first time in my whole life that i asked for a simplified GUI and less options. |

On this topic, though, it would be nice if there was a stand-alone panoramic *viewer* -- especially one that could handle 'spherical' panoramas! |

Thanks for discussing this. Would be fantastic to have such an application on a high end device like this. |

Maybe if you had cam app assistance it would be easier... As in, choose a panorama mode, and then show 1/4 of the previous image overlaid in the cam app and remember to use the same cam settings as previously (exposure, ISO, etc). It probably would be bad at high-res photos, but for wallpaper/web class stuff it might be more than enough and it requires little to no postprocessing.

It seems someone did create a program for shooting panoramic images. (Only a) Trial is available already, but this will be a commercial app. |
Re: Panoramic Image Stitcher Application for N900
Just tried the trial version, a cool app. The picture quality sucks big time but with steady hands can it be improved?
|
Re: Panoramic Image Stitcher Application for N900
With steady hands you could fly a plane in a snowstorm, or walk a rope while wearing a blindfold. With steady hands (translation: tripod stand and alidad) you could take an ideal panorama, and the application wouln't have to compare them to determine their relative positions - it would have only to stitch them accurately.
The fact is, Nokia Panorama application has excellent interface, and not-ideal-but-almost-perfect stitching. However, today as I tried to take a panorama, it crashed during stitching (four photographs, nothing complex) and rebooted the whole operating system. The four photographs and warps.txt are still here. I am attempting to stitch the four photographs with desktop-Hugin, but it's frustrating. Who knows HFOV of Nokia N900 camera? Or its lens type? The idea: create script which would check whether Panorama is running; if not, then check if there are any files in /home/user/.Panoramatmp ; if yes, then check that the latest photographs (beginning from P0.jpg; number of them could be determined from warps.txt, I expect) don't have a corresponding already-stitched Panorama in /home/user/MyDocs/Panorama ; if yes, then stitch the photographs using the warps.txt and add it to /home/user/MyDocs/Panorama . This script could be run either manually, if you don't mind having to remember to click it each time Panorama crashes during stitching, or be typed into Panorama shortcut to run after Panorama closes - just in case Panorama crashed. It should not be run before Panorama opens - it is quite uncomfortable to wait for lengthy process of stitching when you just wanted to take a new Panorama. So, who knows the meaning of numbers in warps.txt? Who would be willing to create a command-line application to stitch the photographs? It should be much easier than porting whole Hugin. Best wishes. _________________ Per aspera ad astra... |

Does anyone have the official figure to confirm my measurement? BTW, using the HFOV and the focal length (5.2 mm, according to EXIF in the pictures taken by the phone), the photo sensor horizontal size comes out as 5.6 mm. Which sounds about right :) |

Sensor is 1/2.5" with width of 5.76 mm so you were 0.16mm off the mark. Not bad for a... what did you say.... "pano-newbie"? |
Re: Panoramic Image Stitcher Application for N900
Thanks, handaxe. Obviously there are a number of rounding errors in all calculations. My sensor width came out exactly at 5.625 mm, I rounded it to one decimal. That puts me only 0.135 mm off :) The 1/2.5" may also be rounded. My distance from target may have a mm or two error. The focal length may be rounded. And finally, my figure gives the size of the active section, the 1/2.5" may be the absolute size.
Having said all that, I would still like to see the official figure :) |
