Google Earth Beaten By Autorendering From Photos

timothy posted more than 6 years ago | from the klicka-har dept.

Earth 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.

Re:Game mods (4, Insightful)

Quarters (18322) | more than 6 years ago | (#23697411)

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.

Re:Game mods (4, Interesting)

maxume (22995) | more than 6 years ago | (#23697477)

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.

Re:Game mods (0)

Anonymous Coward | more than 6 years ago | (#23698023)

Hmmmmmm.... and all this time I thought there were things called "computers" that have no problem doing repetitive tasks. It's almost like they're born to retouch data for continuity and supply a much wanted demand for actual life-like cities for games since a game like that with good play would sell forever. Google hires cars to drive around. That plus this seems like money in the bank.

Yeah that was always a dream of mine as a kid. A fully detailed and accurate 3d rendition of a chosen town. Not necessarily with violent ambitions but with the freedom to do as you wish. But if it's GTA we're talking about I'd like to go on a rampage in Tillamook, Oregon [wikipedia.org] =)

I'm sure the outrage that would commence of real city GTA would be substantial. However if it was marketed as something more mundane it would avoid some concerns I'm sure.

nguy (1207026) | more than 6 years ago | (#23697077)

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.

Re:viewing angle (2, Informative)

BiggerIsBetter (682164) | more than 6 years ago | (#23697181)

It's still very cool considering the small time and cost involved. Even if not mm-perfect, it's still invaluable for travellers making plans and virtual tourists alike.

Re:viewing angle (3, Interesting)

Rei (128717) | more than 6 years ago | (#23697487)

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.

Just look at the castle on the big islands north east corner. It has a hole in the wall that reaches up to the roof and the street on the north east of the castle are way to bumpy.
In this system there is too much aligning going on which at the end makes it look aweful. The google system takes more resources but the quality is much better.

zappepcs (820751) | more than 6 years ago | (#23697173)

I can't remember where now, but I remember some military contractor type company working to clear up image meshing like this on a robotic vehicle program somewhere (at least I think I do, but now can find no links for it). If they clean up the details with revised software, this would be an awesome terr^H^H^H^H^Hflight training sim setup.

The story I read was about creating 3D maps from sat pictures, inserting geodata where it was known, and using this as guidance data for unmanned passenger vehicles like the latest DARPA challenge.

Theoretically, if you can update photos every other day, you could use this to map alternate routes for drivers, and correct inconsistencies in map data for Google maps and Yahoo maps et al.

It's all about the speed of updates. I'd think a single helicopter flying with a rather fancy camera setup (something like they use for capturing a murder scene etc.) could cover a metropolitan area in a day, crunch the photo data, update... presto, accurate maps. Even 8 days is pretty damn fast.

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.

-- But the web games has not really taken off, so now we are betting on this instead, "said Khashayar Farmanbar who is president and CEO of Agency 9.

Since C3 and Agency9 found each other through cooperation with Hitta.se is planning the two companies to work together to promote complete 3-D package to build Web-based services.

-- We will, together with C3 also be able to offer the technology to build 3D services that can be used in mobile phones, says Khashayar Farmanbar.

Both he and Tommy Johansson believe that it is perfectly possible to develop a service that is similar to that from Hitta.se that can run on a mobile.

On the other hand, buying SAAB would also potentially give a whole new meaning to google bot [wikipedia.org] .

Thankfuly, as you mentioned the car manufacturer is now separate, so we won't have to put up with the new invite-only 9-5 Beta! for five years, at which point it would be replaced by a more popular model developed by BMW.

Prikolist (1260608) | more than 6 years ago | (#23697175)

Dunno what's the big deal about, I can't even get the thing to work, it just takes up both CPU's and doesn't show anything... On the other hand I can start up Google Earth and it will work in seconds. But that may be some software bug on my side, whatever.

Anyway, I'm sure this may be cool for people in Stockholm, but unless they plan to expand this to worldwide scale, this will just remain another web's curiosity for the bored and an occasional /.-reading tourist. And, mind you, catching up to Google's amount of maps and images and databases would not be an easy thing to do.

In my experience, direct rendering is by far the most important factor in Google Earth's smoothness.

I have a Compaq nc6400 laptop with an Intel Core 2 Duo and an ATI Mobility X1300 video card. Without direct rendering, I am lucky to get three frames per second when Google Earth is zooming/moving. With direct rendering (through fglrx), the smoothness is incredible.

Same goes for glxgears: full-screen gets me 168 fps with direct rendering, and less than 3 fps without.

SpinyNorman (33776) | more than 6 years ago | (#23697559)

I think you're confusing the download & model building speed (slow) with the rendering & display speed (real-time rotation - SUPER fast)

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.

Re:At least google earth works (1)

SpinyNorman (33776) | more than 6 years ago | (#23697429)

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.

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.

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

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.

Illegal in the States? (1)

Jicksta (760596) | more than 6 years ago | (#23697321)

I thought the reason why Google Maps didn't have ultra-high resolution images was because of government restrictions.

mnb Re:Illegal in the States? (3, Insightful)

Anonymous Coward | more than 6 years ago | (#23697405)

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.)
The COE is still so far back in the stone-ages they want traditional sections run, and are not large users of aerial mapping. (Not as large as they should be.)

That said, the volume of high-res photos out there is huge. We just finished up a state-wide lidar job of XXXXX, with elevations provided (post vegetation and building removal) tight enough to provide 6" contours. The accompanying images are 3" resolution. Where can you get the images? I have no idea.
We do similar work for the FAA. (Only practical way to do obstruction surveys is with photogramitry.) Do they release those 1/4' images? I do not know.

There is no reason to believe Google shows poor-quality images for any reason outside an unwillingness to pay for the acquisition.
Have you seen the high-res obliques Microsoft provides now? Those clearly aren't banned in the name of security.

Ask your local Auditor for a copy of their aerial mapping data - often it is free or for a nominal fee. (varies county by county and state by state in my experience, everything from 10 DVDs for free to $100 per CD)

Google Earth Beaten? (2, Insightful)

MrMista_B (891430) | more than 6 years ago | (#23697341)

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.

Re:Google Earth Beaten? (0)

Anonymous Coward | more than 6 years ago | (#23697401)

Absolutely agree with MrMista_B... Slashdot summary of the story is terrible.... This "demo" has small converage, low resolution geometry models, and absolutely no geo-spatial meta data, so in what way does it "beat Google Earth." Beside, how do you know how long it took Google to generate their models of equivalently-sized cities. If they are generated from laser data, don't you think it probably takes less than 8 days on a million machine cloud?

Animats (122034) | more than 6 years ago | (#23697391)

Very nice. It's beautiful from high angles, and not too bad from low angles. (Middle-click and hold to change view angle, mouse wheel to zoom, left click to pan.) 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, they just need more oblique photos in the difficult areas.

spandex_panda (1168381) | more than 6 years ago | (#23697551)

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. I can't look at the final product now, I reckon it got /.'ed into the ground, but the next 'clever' thing to do once you have a big ol' DEM is to make an algorithm that squares up the buildings! I wonder if we can digitise all the old film photography which covers a majority of the world, and image matching from that, can google automate the task of creating a DEM of the entire world to accuracies of less than 1m ? That would be cool.
