Photosynth - tavalliset valokuvat 3D maailmaksi

Jukka Wallasvaara — Wed, 28 May 2008 06:52:00 GMT

Photosynth on mielettömän hieno teknologia Microsoft Live Labs:ltä joka muuttaa käsityksen valokuvien katselusta ja hyödyntämisestä. Oheisessa videossa näkee millaisesta toteutksesta oikein on kyse.

Sovellus ottaa ison kokoelman valokuvia, analysoi niiden yhteläisyydet ja luo niistä kolmiuloitteisen maailman jossa niitä voidaan tarkastella.

Photosynth:llä voi kulkea tai lentää kuvista toiseen ja katsoa kuvia aivan uusista kulmista. Kuvia voidaan zoomata saumattomasti selaimella vaikka kuvat olisivatkin korkearesoluutio kuvia - on ne sitten mega- tai gigapikselien kokoisia. Tekniikalla voidaan nähdä, mistä eri kuvat on otettu ja miten ne sijoittuvat toisiinsa. Photosynth -kokemukseen tarvitaan siis tavallisia kuvia. Ne on voinut ottaa sama tai eri henkilö ja niissä voi olla sekaisin eri kameroilla, resoluutioilla ja ajankohtina otettuja kuvia.

Jokainen piste kuvaa kuvan tunnistepistettä, jonka avulla kuvat liitetään toisiinsa. Nämä yhtäläisyydet tunnistetaan automaattisesti, joten käsityötä ei tunnistuksessa tarvita ollenkaan. Kuvat sijoitetaan 3D malliin, jolloin kuvista voidaan helposti siirtyä toisiin.

Vertaamaalla useampaa kuvaa toisiinsa, saadaan rakennettua todentuntuinen ympäristö, jolloin kuvauspaikka voidaan kokea täysin uudella tavalla. Kuvat sijoittuvat lomittain ja niiden liitokset tehdään uskomattoman joustavasti toisiinsa.

Photosynth hyödyntää Seadragon tekniikan häkellyttävää pehmeää renderöintiä ja zoomaus toiminnallisuuksia.

Digital Photography Resources

Sarah Perez — Tue, 26 Feb 2008 04:32:00 GMT

If you're into digital photography, I just discovered a great resource that you'll want to check out via Brian Johnson's BufferOverrun blog. Brian created a list of links using Microsoft Live Labs Listas, which breaks down the resources into the following categories: Digital Camera Resources, Photography Education and Techniques, Photo Software and Sharing, Photography Podcasts, and Photography User Groups and Events. The list features some Microsoft resources, like PhotoSynth and some non-Microsoft resources like Paint.NET's Wikibook. Even if you don't have time to peruse the whole list now, it's one of those gems that you find and just have to bookmark!

Sultanahmed Square Photosynth Collections

Nuri Cankaya — Fri, 04 Jan 2008 09:14:00 GMT

By using Photosynth in Turkey we have created some important collections. By the help of photo enthusiasts we have taken more than 5000 pictures in the historical Sultanahmed Square. The first two collections that I will demo in the screencast is Blue Mosque and German Foundation.

German Fountain, Istanbul ,Turkey
The German Fountain (in Turkish Alman Cesmesi) is a gazebo styled fountain in the northern end of old hippodrome (Sultanahmet Square), Istanbul, Turkey and across from the Mausoleum of Sultan Ahmed I. It was constructed to commemorate the second anniversary of German Emperor Wilhelm II's visit to Istanbul in 1898. It was built in Germany, then transported piece by piece and assembled in its current site in 1900. The neo-Byzantine style fountain's octagonal dome has eight marble columns, and dome's interior is covered with golden mosaics.

Blue Mosque - Sultan Ahmed Mosque, Istanbul, Turkey
The Sultan Ahmed Mosque (Turkish: Sultanahmet Camii) is a mosque in Istanbul, the largest city in Turkey and the capital of the Ottoman Empire (from 1453 to 1923). The mosque is one of several mosques known as the Blue Mosque for the blue tiles adorning the walls of its interior. It was built between 1609 and 1616, during the rule of Ahmed I. Like many other mosques, it also comprises a tomb of the founder, a madrasah and a hospice. The Sultan Ahmed Mosque has become one of the greatest tourist attractions of Istanbul.

The Shuttle Backflip Photosynth

Larry Larsen — Tue, 21 Aug 2007 16:06:00 GMT

You may have noticed a few new Photosynth collections going up recently. The latest one was the Shuttle on the way to the launch pad, which was not only one of the most interesting collections yet, but also logistically impressive (apparently the Feds tend not to let choppers fly near billion dollar spacecraft as a rule.)

But here's a Photosynth you might have missed. During the docking process, STS-118 did a backflip so the underside could be extensively photographed by astronauts in the International Space Station. That's when they found the 3" chunk of important tile missing. A Photosynth of this maneuver was constructed and you can check it out here. The imagery is good enough you can almost read the writing on each tile in some pictures.

BBC Launches Six Photosynth Collections

Larry Larsen — Mon, 04 Jun 2007 17:00:00 GMT

The BBC in conjunction with Microsoft Live Labs has launched six photosynth collections including the following areas Ely Cathedral, Burghley House, Royal Cresent, Blackpool Tower Ballroom, Scottish Parliament Building, and Trafalgar Square.

The screenshot at left is the stained glass in Ely Cathedral. Don't forget you can use the wheel on your mouse to zoom in and see all the detail.

If you're not familiar with Photosynth, you can check out this TED talk from Blaise Aguera y Arcas, the lead behind Photosynth. We got a chance to talk to Blaise before CES in January, he's one of those amazing personalities where several minutes into the conversation you realize he's working with a completely different processor than the rest of us.

Photosynth and Seadragon offer a glimpse at the next great UI

JD Lewin — Mon, 08 Jan 2007 02:30:00 GMT

If you’ve seen Minority Report and watched with glee as Tom Cruise effortlessly navigates piles of media with lightning speed using only his hands, you’ll immediately recognize Seadragon. Blaise Aguera y Arcas and the team at Windows Live Labs have created an engine for managing large collections of images effortlessly. Through their own special brand of hot sauce, the team has been able to build software that loads only the pieces of large images that it needs at any moment in time. This breakthrough allows the user to experience their collections of images instantly. By adding Photosynth to the recipe, the team is able to stitch images together and determine the three dimensional space where pictures were taken.

When the power of Seadragon and Photosynth are combined with images from many different sources, the potential applications become very exciting. Fusing the photos of a particular location taken by multiple people, geo-data can be learned as opposed to manually entered. Now if only we could merge these technologies with some gloves with glowing fingers…
