Google Earth Beaten By Autorendering From Photos 176

Flu writes "Sweden's major engineer newspaper NyTeknik writes about a new technology which is used to automatically convert 60.000 aerial photographs of Stockholm, Sweden, into a 3d-world, similar to Google Earth's rendering of major buildings in some US cities. But unlike Google's laser-measured rendering, this technique took less than 8 days (including the photography) to automatically generate the 3D-model of Stockholm — which includes every building and details as high as individual trees! The program was developed by C3, a subsidiary of the Swedish defense industry company SAAB, together with a PC gaming company called Agency 9. The complete article is available (sorry, Swedish only), but the 3D-rendering of Stockholm is available as a Java applet from the Swedish phone-dictionary service Hitta.se (tick the checkbox — it's an ordinary disclaimer, and click 'Till 3D-kartan')." The technique used gives a cool water-color look to the scenes, too.

      Probably never. Even if the resolution was adequate (which it isn't) and you could somehow extrapolate street level views from aerial photography (you can't) there are still the issues of photo retouching and missing information for stacked spaces. Unless the plane could somehow magically photography the entire city at predetermined times of day and days of the year so that all of the images were lit identically and cast shadows in the same direction/length there would be an astronomical amount of work needed to retouch the source data for continuity. On top of lighting and shadows you'd have to remove all representations of people and cars, etc.. from the source data. Assuming you could get all of that done there's still the problem of missing data from stacked surfaces; tunnels, elevated trains, subways, overpasses, building interiors, etc... None of those spaces can be represented via extrapolated aerial photographs.

      With the amount of dataset rework / additional work that would be necessary to create an artistically pleasing & competitive game with such data it will be a long long time before you see it even coming close to being more cost effective than hand creating a world to fit a game's specific needs.

        I would think that they could extend the technique to process 4 or 5 sets of data in order to eliminate things like shadows and fast moving objects (so cars, people, construction, etc). Probably not cost effective, but I don't think you would need to worry about capturing identical shadows, I think you could make sure that you captured different shadows and then process them out.

          But also remember, there is a LOT of continuity in cities. Especially on commercial buildings.

          The best one I could think of are those huge industrial chillers that commercial institutions have on their roofs for their AC. There aren't a billion models of them, so if you could somehow detect the model of the AC units in one photo you already have a good amount of geometry going for you.

          Then you figure out what cars are on the street. A Prius has a specific shape that really doesn't change from Prius to Prius, so you know some of the details about every car on the street.

          Manholes are a standard size, if you were to figure out what type of manholes you had in your picture you have more data. How many police boxes and fire hydrants are there in a photo of a NYC block?

          If you gave me a super-high-resolution photo of a city block I could find literally hundreds if not thousands of points of reference. Soda bottles and cans... the list goes on

        You're right if you assume that one wants a perfect representation directly derived just from the aerial photos, but that's not necessarily the case. From the aerial photos you can reconstruct an approximate 3D model of the facade of the buildings (by making assumptions about where shadows are or by combining multiple photos from different perspective) and derive a unifromly lit texture for the building. It's not all that difficult with buildings since those tend to be symmetrical and have lots of repeating
        • Well, I don't know about strictly accurate buildings and whatnot but there was a street racing game a few years ago that was set in Sydney, Australia. It was promptly banned because they figured that "car hoons" (Australia treats car enthusiasts slightly worse than they treat paedophiles) might use it to "practice hooning".

    The techniques for recovering 3D shape from photographs have been well known for a while. But if all the pictures you use for the 3D reconstruction are from overhead, the street level view will be missing all the stuff you can't see from overhead. It may be called a "3D model", but it's not a complete or accurate 3D model.

    If you want decent street level views, you really do need street level photographs. And laser scanners are still a lot more reliable than image based 3D reconstruction.

      How long do you think it'll be before there are street level views of, say, Devil's Canyon, the middle of the Namib desert, or halfway up K2? The beauty of this is that it lets you get a map of virtually anywhere from the air. No, it's not perfect. It looks kind of like a cross between a Salvador Dali painting and Magic Carpet; around every corner I expect to see either a melting clock or a balloon picking up mana spheres ;). But the fact is that it was able to be assembled with minimal computational effort from a resource (aerial photos) that is already widely available for many areas -- and, for areas where it's not, can be rapidly gathered. Sounds like a winner to me.

    I'm posting the article in English here with some changes due to Translate.Google not being able to translate everything 100%.

    Hitta.se beats Google Earth
    with new 3D-technology from Saab.

    Search company Hitta.se has a new Web service that is better than Google Earth to show Sweden in a 3D view. In Stockholm there, for example, every single building as a realistic 3D model.

    With the help of robotics from Saab and the Swedish software for computer games Hitta.se search company has developed a Web service that shows Sweden in 3D and which is clearly better than the corresponding service from Google Earth.

    Directly in the browser, users can zoom in, tilt and turn the flygfotograferade views across the country. With the help of altitude measurements images of the land are created where the mountains and valleys appear with genuine feeling of depth.

    The new service, which launched May 29, is also all buildings from Stockholm, in the form of realistic 3D models.

    Although they can be turned and turned and seen from any height and angle.

    Later this year, including the second appearance of Sweden's largest cities as a complete 3-D models.

    The major competitor in the show Sweden in 3D is Google Earth. But there are only a few dozen 3-D buildings from Stockholm and a few other cities.

    Google's 3D view of Sweden was also much lower quality than that Hitta.se offer. Both in terms of image resolution and altitude.

    -- We have created 3-D feature to give users a more fun and more realistic ways to use our maps, "says Rui de Sousa Brit who is president and CEO of Hitta.se

    But the new service does not yet cover all planned features. Therefore, it's "sneak launched" and goes by the name of "the lab" on the company's website.

    Moreover, such as some 3D buildings refined when the houses angles can be a little crooked and some facades have bad sharpness.

    The technology used was developed by the Swedish companies C3 Technologies in LinkÃping and Agency9 in Lulea.
    C3 is a subsidiary of Saab and develop technology that has its origin in seeker for robots.

    The technology is based on high resolution aerial photography with carefully calibrated cameras. In order to build 3-D model of Stockholm, which covers an area of 200 square kilometres was 60 000 images from 600 metres above sea level, which took three days.

    Then, it took only a few more days to automatically create 3-D model, where even individual trees are included.

    Tommy Johansson who is president and CEO of C3 know that some defence in the world have developed similar technology. But he is not aware of anyone else who introduced the technology for civilian purposes.

    -- We aim to launch our technology globally and believe that, for example, urban planners and businesses similar Hitta.se can become our customers, "says Tommy Johansson.

    Other companies based 3-D models of entire cities primarily use lasermÃtningar to collect 3D data. For example, Google and Microsoft for their service Virtual Earth.

    It is a technology that is much more costly and time consuming than the C3's way.

    Photo and mapping services from Google and Microsoft require users to install special software on your own computer. In Google Earth in the form of a stand-alone program and the Virtual Earth as a plug which is available only for Windows.

    But Hitta.se 3D runs directly into the browser by using javateknik and works for most operating systems and browsers.

    -- I think that both Google and Microsoft may have some problems with sleep when they see the new service from hitta.se, "says Tommy Johansson.

    In order to be able to present all 3D data in the new map in the form of realistic buildings used technology developed for computer games.

    It comes from the Agency 9 of Lulea.
    The company began by building a so-called rendering engine for web games. Eg. software that draws up 3D environments on the computer screen.

            Zoom in as far as you can go, tilt the model as far close to horizontal as it will go, then spin the model around it's center point by dragging the compass dial in a circle - you can do this even as the model continues to download and refine itself.
        • This hitta.se 3-D seems to first be buiding a 3-D model, skinning it with photos (maybe tranformed on the server?), then displaying it with D3D or OpenGL. The graphics part of it is ligtening fast - try getting in close to the ground at a low angle (i.e. where you can really see the 3-D model) then rotating the 3-D world with the dial-thingy... I have an old Radeon 9200 card and it still rotates and displays the 3-D model in real-time as I spin it around - damn impressive.
        • I've never had problems with speed on Google Earth.

          Even my Pentium 3 laptop with Intel 815 graphics can do it fairly well.
          Of course there are some pretty horrendous graphic glitches but it does work. ;)

    It seems as if the geometries are calculated from scratch in real time.

    This article is gonna have quite an effect on their servers ;)

    At first I though: *yuch* this is awful with the geometries being at very low resolution and with strong artifacts. But as the script kept processing it's looking really good by now, except that it's still hour-glassing and I can't zoom in after minutes.

      That wasy my initial thought, but (having watched it load, but not read the (F) article) now I'm thinking perhaps it's just an incremental load of a height field.

      The height-field v. polygon guess is also supported by seeing how bridges are handled - for example, with flat sides that include images of boats striped up them.

  • I thought the reason why Google Maps didn't have ultra-high resolution images was because of government restrictions.
    • by Anonymous Coward
      Considering most of the high-res aerial mapping is done on a county-by-county basis (rarely even state-wide) the large number of governmental agencies Google would need to contract with to provide sub-foot imaging is immense. The most common user of high-res aerial mapping is county GIS departments, and very few of them ask for the overlapping stereo images needed to model heights. (Or you could do it with lidar, but again most county auditors have little use for the height data.)

  • Beaten how, exactly? This is just one city. Google Earth covers a heck of a lot more than once city. Sure, the rendering is fine, but again, compared to Google Earth as a whole... eh, not what I'd call "beating Google Earth" by any stretch.

      But I would be genuinely shocked if Google doesnt have similar tech being made.

They put in enough photographs to have side images for most of the buildings. It's really impressive when you look at a courtyard from the inside.

    There seems to be some support beyond the height-map level. It usually misunderstands bridges, but in at least one place, it got a multi-level situation right, so they have the right machinery, t

  • of this new software is that it seems to be fairly automated from the start. Maps all around the world are created using aerial photography, and all the DEM's (digital elevation models) usually represented by contour lines were made by people digitising by hand from stereo aerial photography. This method has created a 3D model of a whole city, in 6 days, I reckon mainly using automatic methods of image matching and DEM creation. There are aerial laser scanners which do the same thing, but are very expensive

  • The chief accomplishment is not that this produces better results than what Google or MSN Live has to offer. It doesn't. There are a lot of odd things, many shapes are a bit off, it can't handle tall buildings at all and if you have something like a bridge the ground level rises up to it. Still, if you're gonna go out and measure every house using lasers, we'll only see 3D views of the biggest US cities. This way it is possible to do it for smaller places, like little Sweden.
