The first full-res stitch of our panorama taken at the top of the Corcovado mountain near the base of Christ the Redeemer in Rio de Janeiro, Brazil. This digital photograph consists of a total of 6223 pictures taken at with a Canon t2i, a 400mm lens, a 2x extender, and the new GigaPan Epic Pro. It has around 67 gigapixels, which we believe is the world record in terms of resolution. There are some artifacts due to exposure inconsistency and vignetting that we hope to address in a later update.

RioHK is a collaborative gigapixel panorama project between IMPA (Rio de Janeiro) and HKUST (Hong Kong) led by Professors Luiz Velho (IMPA), Diego Nehab (IMPA) and Pedro Sander (HKUST).

    Maravilha. Dê um zoom onde quiser ver detalhes.

    This picture is the biggest, because these pixels are more real than those "bigger" pictures, which are more magnified for some odd reason.

    This is awesome, but please, tell me, why do you need over 6000 pics to cover this area, even with 800mm when you could cover the same area at full zoom with 1/10 the amount? I guess theres a natural explanation to it, but would love to learn more, how and why? Thanks

    Do you have plans to process the 150 plug gigapixel Sugar Loaf image and upload it, or are you going to recapture this image? I am referring to the image in the pdf that was used for the presentation.

    Dear Castillonis, The pdf link in the above comment is not a paper, but a set of slides from a recent talk at the VISGRAF Seminar. The credits in the last slide are meant to list the references used to prepare the talk and allow the speaker to describe these references verbally. But, I agree with you that the results on dehazing by Neel Joshi and Michael F. Cohen are really impressive. So are the results Pablo d'Angelo for vignetting correction.

    Stoney Vintson (August 22, 2010, 03:05PM )

    Who ever wrote that paper should add some better references than just a name at the end of the paper. Did you see two of the Microsoft papers on dealing with atmospheric conditions. There is an example of Mt Rainier photographed from 90 kilometers away. It is impressive.

    Those are probably the most similar lenses that were available. You can buy a CF adapter to use V series lenses on an H series body. I would use a Zeiss V series lens with a CF adapter on an H series body. Personally I want to use Contax 645 bodies and Zeiss lenses with P65 backs. Though I may be able to get two PhaseOne bodies ( made by Mamiya ) for PhaseOne which concentrates on making great digital backs.

    @Castillonis, yes I realize why the two cameras- rather it's the two lenses of two different focal lengths that were used simultaneously that puzzles me I guess.

  16. Stoney Vintson

    Stoney Vintson (July 31, 2010, 10:28AM )

    They used more than one camera in order to reduce mismatches between photographs due to a subject that moves. ( The 150mm Hasselblad is not as good as the 120mm macro or the 300mm ) I have used a prototype that can hold six point and shoot cameras. I have been told by Holger that Clauss has an imager that can hold four Canon 500mm f/4.0 lenses. Lionel from Kolor said that it can hold two 600mm f/4.0 lenses. I have used the Canon 500mm f/4.0 and it is an excellent lens. Though a PhaseOne p65 digital back and a telephoto would be better. Especially the increase in dynamic range and lower noise. ( The pixels / cm^2 ) The lenses are amazing.

    @Castillonis, There is a gigapixel shot at the Glastonbury 2010 festival for Orange which was created using two Hasselblad H4D-50 cameras. They used two different lenses though- 150mm on the top camera and a 100mm lens with tilt shift adapter on the bottom. Not sure exactly why the two lenses but the results are really nice. The Facebook angle regarding tags is an interesting feature as well. You can can check it out here: www.allfacebook.com/2010/07/orange -uses-facebook-to-power-giga-pixel-photo Will open in

    Yes, I saw online that Luiz spent time at MS Research and thought he might. I know Michael (& Matt) as well, as I live in Seattle. They have had so many things "on the stove" so to speak in relation to this type of photography. It is a nice to see work done in this area to address these issues. I do many high-resolution infrared panoramas with my scanning back camera and would sure like to see/find more research related to combining these images with those shot normally to make use of infrared's ability to capture such fantastic detail over great distances without effects of haze etc. know any?

    Stoney Vintson (July 31, 2010, 09:42AM )

    If possible, you need to use a different lens than the Canon 100-400mm f/4.0. The vignetting is extreme at 400mm. The Canon or Nikkor 300mm f2.8 lenses exhibit much less vignetting. Read Pablo D'Angelo's presentation on vignetting. hugin.sourceforge.net/tech/icvs200 7_presentation.pdf Will open in
a new tab or windowKolor demonstrated an implementation for haze removal at the April 2010 IVRPA conference in Tucson. It uses a different method, but is similar to the Kaiming Hei paper that uses single images and a depth map. research.microsoft.com/en-us/um/pe ople/jiansun/papers/dehaze_cvpr2009.pdf Will open in
a new tab or windowI believe that Kolor used the dehaze filter on their Paris 26 gigapixel image. Hopefully they will start to sell it soon. I use a LCDVF viewfinder and live view to attain much better focus. This is a huge improvement. www.amazon.com/LCDVF-LCD-Viewfinde r-Digital-Cameras/dp/B003A2BU5E/ref=sr_1_1?ie=UTF8 &s=electronics&qid=1280596645&sr=8-1&n bsp;Will open in a new tab or windowYou should plan to do captures in the morning when the temperature is lower and there is less thermal energy in the atmosphere. Also, you can use a second camera to continually shoot a digital calibration target during the time of the capture. This would allow you to adjust each row or section of a row for changes in exposure and white balance. I learned from my project in San Francisco to never capture in the afternoon when large distances are involved. There is a new autofocus feedback mechanism in the new firmware, but it is not a panacea for those who do not know how autofocus works. Manual focus with a viewfinder is always better, but it takes time. Unfortunately I have more difficulties with Nikon live view and magnified viewfinders. Currently the Canon display of live view works better This composition is good, but for other large gigapans, it would be best if people think about composition before starting capture. Once you start to capture a large panorama it is difficult to think about composition because you are focused on the capture. In the future, I plan to capture large panoramas with more than one imager and use medium format cameras. I am considering using multiple PhaseOne P65 digital backs that can capture at a rate of one photo per second. This sensor is twice as large as a full frame DSLR and has much better dynamic range. Also, the lenses are sharp from corner to corner

    Thanks Bohonus. Luiz Velho happens to know Neel and Michael (and met the latter at SIGGRAPH 2 days before). This paper has great results and I look forward to implement it as a pass in our stitcher software.
