Fast Generation of 3D City Models

FleaPlus writes "New Scientist and UC Berkeley News report on research by Avideh Zakhor and Christian Früh on rapidly and automatically generating photo-realistic 3D models (coral cache) of city environments. This is reminiscent of research mentioned here in March, although the approach is rather different. Applications for areas like urban planning, entertainment, emergency response, and the military are discussed. Zakhor's group is also working on 4D systems, to allow for recording of events over time as moving 3D models."

Janitha (817744) | more than 9 years ago | (#12463195)

But that was mostly done with scanning the distance around a given point (or several points), and it had no image but just a depth map, even if there was image it would be used to simply identify more the object at a given point, not to this scale.

This is quite impressive, yet they still have to work out those glitches that are quite visible. Its fast, but they are giving away precision for speed.

The other thing I don't understand is the used for rapid generation of these, speed is good, but cutting down on how accurate it is for speed is not acceptable. A better view would be pre-rendering the images with more precision/accuracy. Not like buildings come and go every day.

Re:SGI? (1)

dclaw (593370) | more than 9 years ago | (#12464500)

true, it was not done to this scale... and was certainly not photo-realistic... but, it was still distinct enough to make out exact buildings and landmarks.... and certainly enough to make out billboards and other such high visibility marketing.... and the last iteration I saw of such technology, which was about 2 years ago was using multiple satellite images of an area:

1 or more top down pictures of the area, plus usually a 4-way side view of the area... giving "recognizable" quality representations of buildings that were rendered to accurate size.

anyway... yeah..... further explanation concluded.... I was at work when I wrote that quick blurb....

Eric Bin Raymond: The September 11th Conspiracy Revealed

When you have a crime to investigate, and you have no suspects, where do you start? Obviously you begin by looking at the person or persons who have the most to gain by perpetrating the crime.

This is why we must consider: who had something to gain from the disasterous crimes of September 11th? Obviously not Osama Bin Laden [afghan-web.com] , who would net no financial windfall from the destruction of the World Trade Center and the Pentagon. Although he has loudly applauded the "terrorist" acts of September 11th and even tacitly taken credit for them, there is no reason to believe that he is anything more than a bandwagon jumper. Being blamed for the destruction of the World Trade Center has done more for his image than any amount of militant Islamic rhetoric.

But if not Bin Laden, then who?

It so happens that on December 11th, "coincidentally" 2 months after the tragedy, Credit Suisse First Boston quietly agreed to pay out US$100 million in order to settle an 18 month old investigation into its handling of certain high-profile technology IPOs (Initial Public Offerings). One of the most controversial amongst these being the IPO of VA Linux Systems, Inc. (LNUX) [valinux.com] .

VA Linux Systems, Inc. [valinux.com] , now known as VA Software [vasoftware.com] , is widely derided as a poster child of the dot-com bust, though inexplicably still in business. At the time of the IPO, VA Linux (Software) [linux.com] shares opened trading at nearly 10 times their $30 offer price, closing the first day of trading at $239.25. This meteoric rise made many early investors rich, strangely on account of a company which purports to sell a hobbyist operating system which can be obtained for free on the Internet [aol.com] . "The VA Linux [msn.com] initial public offering is a prime example of market manipulation in an IPO by investment banks, their customers and the issuing firm," said Steven Schulman [jpfo.org] , a partner in the law firm Milberg Weiss Bershad Hynes & Lerach, which specializes in filing shareholder suits.

"Because certain favored customers of the investment banks agreed to buy shares in a new issue at inflated prices in the aftermarket (in return for getting an allocation of the shares at the initial offering price) the share prices to which the IPO eventually soared were actually driven by artificial market forces," continues Schulman.

But what does the VA Software (Linux) [valunix.com] IPO have to do with the attacks on September 11th, and what has that to do with the Credit Suisse settlement? Well, considering that VA Linux (Software) [windows2000.com] got CSFB into trouble in the first place, it stands to reason that the VA Linux (Software) [vaginux.com] Board of Directors were complicit in the stock fraud from beginning to end. As the investigation progressed against CSFB, the unscrupulous VA Software/Linux executives, their pockets bulging with filthy lucre plundered from trusting, hard-working investors, must have realized that their days in the country club were numbered if the SEC discovered their wrongdoings.

The SEC, or Securities Exchange Commission [sec.gov] , is a federal regulatory agency, and cannot be bribed. Therefore, with a possible stint in federal prison looming large [goatse.cx] , Larry Augustin and the rest of the crooks, including outspoken gun violence advocate Eric S. Raymond [tuxedo.org] , decided to undertake more active means to halt the investigation.

The Plan

It so happened that all the evidence in the CSFB/VA Linux [linuxsucks.com] investigation was held at the SEC Northeast Regional Office in Manhattan. More specifically, 7 World Trade Center, Suite 1300. The board decided that a simple burglary or arson attempt would not be satisfactory to destroy the evidence; anything so simple had a significant chance of being botched, and regardless of success would leave too many witnesses or living accomplices.

It was then that Eric S. Raymond [nra.org] suggested something he had read in a book by Tom Clancy. Crashing two planes into the World Trade Center Plaza would guarantee the destruction of the SEC offices, killing the operatives and possibly a number of SEC investigators at the same time. The plan seemed flawless, and would cost little more than the price of a few plane tickets. In a secret session, the board voted unanimously in favour of Eric's suggestion, and began to put it into action.

VA Software/Linux [vashaftware.com] , at the time of planning the attacks, had no shortage of H1-B visa workers, who they employed for the purpose of writing and improving hacking, encryption, and other terrorist tools for the Linux operating system. It had been decided that a hand-picked few of these foreign H1-B workers would be used as the "patsies" in the operation. A contest was held, and the most zealotous Linux advocates were chosen for this secret assignment, direct from the board of directors. They accepted their mission after being told that, if successful, it would guarantee the adoption of Linux in the desktop market.

Alan Cox [analcocks.com] was brought into the fold to provide some planning and logistics for the mission. It was he who determined that since there was no adequate flight simulator software for Linux, the patsies would need to train at a flight school in order to pull off the plan successfully. It was also his idea to hijack a third and fourth plane for the purpose of crashing them into Washington D.C., to express his extreme rage over the DMCA [napster.com] , or Digital Millenium Copyright Act. The board of directors agreed with this addition to the plan in the hopes that it would help divert attention from the purpose of the WTC attack.

The H1-B workers were given false identities by using Linux hacking tools [gnu.org] . Once they had attended the necessary flight training, they stayed at the Massachusetts home of Richard M. Stallman [stallman.org] for a brief "faith building" retreat. During this time spent at the house of Stallman, between the nauseating stench of patchouli, Stallman's incessant, pitiful recorder playing, [gnu.org] and Stallman's droning seminars on the grammatical and syntactical accuracy of various statements by Microsoft representatives, the H1-B workers were effectively hypnotized to the point that they were ready to lay down their lives for Free Software. It was then that they departed for Boston's Logan International Airport to board the planes.

(The preceding inside information has been obtained from a credible source close to the VA Linux/Software Board of Directors. He/she is in hiding for obvious reasons in light of this damning evidence, but has presented hard, physical evidence of VA Software/Linux's complicity in the events of 9/11 to federal investigators.)

i suppose there is no room for relativism in the world. however, if there was then i do not understand why the united states is the only country in the world that knows what is right and every one else needs to be saved. please keep your xenophobic and arrogant opinions to yourself. it is not the united states' job to save everyone. we cannot even save ourselves. and even if that was our job, how is forced starvation of a people through sanctions followed up with massive bombing and military occupation helpful? i'm sure the germans thought they could save us during world war two. point is: the united states does not have some sort of righteousness attributed to it just because it is the united states. we murder and plunder and use imperial aggression just as much, if not more, than the next country. if it is wrong for another nation to do it, it is wrong for the united states to do it too. iraq was not about defense and it is not about liberation. if we were interested in liberation we would stop funding brutal dictatorships and training human rights violators in latin america.

Re:Military, eh? (-1, Offtopic)

Anonymous Coward | more than 9 years ago | (#12463275)

Most of the tyrants which were toppled recently did so without the U.S. bombing towns and spreading false rumours about alleged WMDs.

It looks more to me as a case of "let's make absolutely sure to be there when Saddam Hussein loose his grip to power! Otherwise we might get something there not fitting with our political agenda."

In fact the number of tyrants toppled with the help of the U.S. is rather small compared with the number of tyrants installed either by the U.S., supported by the U.S. or at least accepted by the U.S. (No. Writing diplomatic notes to tyrants that having free and fair elections might yield some advantages doesn't count as 'helping topple a tyrant'.)

umm actually democracies do start wars. in a democracy the majority decides everything, so it is basically mob rule. if all of a sudden the majority wanted to take away rights from all white people it could happen. obviously democracies can be oppressive. For example take nazi germany - they democratically elected Hitler into power.

and a military is about self-defense. it's pretty naive to think that there will never be evil. we will always need a military in order to ensure the safety of our citizens.

lidar (4, Interesting)

kebes (861706) | more than 9 years ago | (#12463190)

This technique should be replaced with (or combined with) LIDAR techniques. LIDAR (Light Detecting And Ranging) is like a laser version of radar, and it can be used to generate 3D maps of objects or topography fairly quickly. A LIDAR-enabled plane can do a fly-over of a city and quickly generate 3D maps. For instance, check out these LIDAR images [loc.gov] of New York pre and post 9/11.

I've always thought that these 3D maps of cities should be combined with satellite imagery so that you could 'paint' the rooftops onto the buildings and streets. In fact, most satellite images are at a slight angle, allowing you to paint the facades of buildings. The techniques from TFA show how you could paint even more facades in the 3D model/map fairly easily. I think the LIDAR data would greatly simplify the painting algorithm, since the correct 3D shape of every object is known.

I can't wait for the day when we can browse 3D maps online of any city. It would be useful for surveyors and architects of course, but also useful for planning trips, learning geography, and so on.

I'm into panoramic photography, and always wondered, how involved would it be to mount a fisheye lens to a video camera mounted on the front left corner of a car hood, and drive up and down each street of a city (both directions) including all alleys, connected to a REALLY GOOD gps system, then have a QTVR composite that lets me manovuer at will through the city, up down/back right, turn, spin... I could have a map of a town, pick any street and orientation as a start point, and then just turn and advance- and the video would be of my 'location' as chosen...

what kind of database/live edit system would it take to combine all that video to make transitions around corners smooth at the point where the video lines crossed on perpendicular streets?

Re:lidar (1)

Hast (24833) | more than 9 years ago | (#12470635)

I'd say you'd be better off using multiple cameras so that you capture multiple directions at once. If you don't you'll probably have a very hard time making the result match up. (Ie have the same spot in the road in both directions at the same time.)

There are systems like this however. If you look up computer vision research you can typically see stuff about systems that automatically build a "map" of the world. (Typically used with robots.)

Ok way off topic but .... Uh the futurist used Cubism. Picasso was a cubist. Braque was a cubist. Filippo Tommaso Marinetti was a futurist. The futurist basically stole the cubist aesthetic and applied it to the instudrial era of the 1920's "Cubism had run its course by the end of World War I, but among the movements directly influenced by it were Orphism, Purism, Precisionism, Futurism, Constructivism, and, to some degree, Expressionism." "Futurism is an Italian modernist movement celebrating the technological era. It was largely inspired by the development of Cubism. The core themes of Futurist thought and art were machines and motion.http://www.artcyclopedia.com/>

5. You cannot admit that you don't have professional usage of Linux outside server markets.

6. You cannot admit that most of the joe user out there when told that there is linux will respond, what is that?

7. You cannot admit that there is no professional printing capabilities in linux.

8. You cannot admit that you are a masochist (otherwise why would someone spend hours playing with scripts,
and recompiling programs that are available for Windows?)

9. You cannot admit that there is no professional desktop publishing done on Linux.

10. You cannot admit that no one in their right mind would do professional video editing in Linux.

11. You cannot admit that linux sucks when it comes for gaming/home entertainment or education.

12. You have problems in understanding Windows, and you will blame your own incompetence on Microsoft.

13. You have problems in pointing a clicking, but have no problems in wading through cryptic scripts written by lunatics.

14. Nothing will get past that shit that fills your head, you will not admit to any facts.

15. You can't admit that naming of linux components, packages, and others are weird and fits profiles of troubled teenagers. gentoo, lgx, rpm ....

16. You feel angered because you were left out by microsoft's Media technologies, they support Mac, Sun sparc, but not linux.

17. You feel inferior deep inside but unable to admit it, you don't have a database as easy and powerful as Access.

18. You cannot tell that not a single office package outside Microsoft's is worth looking at or bothering with.

19. You don't know that your CD recorder software sucks.

20. You don't have DVD-RAM, DVD-R, DVD-RW support in your pathetic OS.

21. While the rest of the world moves on, you're stuck in a stone age technology that needs third party software to boot into GUI.

22. You act out of prejudice, you kill file domains and users of specific news readers while you ignore the bullshit that your fellow linux losers post.

23. You don't know commercial support in Linux is almost non existent.

24. You miss the fact that companies are leaving linux because of the chaos, and the cheap linux losers who are unwilling to pay and support hard work, Corel, gaming companies,...etc.

25. You are unaware that linux has no terminal services (there is a lame one that no one uses), and commercial support for it is not happening.

26. You are unaware that setting up servers on Windows takes couple of minutes while on linux, good luck playing with configuration scripts.

27. You cannot admit that support for USB on linux is laughable at best.

28. You think that Linux is better because slashdot told you so.

29. You spend countless hours flaming people because they post their opinions about your oh so cool linux and your attitude, instead of researching things for yourself and understanding fact in order not to look this stupid.

30. You think that anyone who uses linux has a clue.

31. You think that linux cannot crash.

32. You think that everyone is interested in your conspiracy theories about Microsoft (or should i say M$ in order for you, teenagers to understand?), and how they destroyed linux, ...etc.

33. You keep ignoring the fact that thousands of linux servers get hacked every year, but it takes one Windows server hacked to get you and your fellow linux idiots to dance and celebrate.

Wonder how it fares with European cities (4, Interesting)

Matthias Wiesmann (221411) | more than 9 years ago | (#12463359)

All the examples shown in linked article are US style cities, with straight roads and relatively simple roughly cubical buildings. I wonder how this technique fare with more complex buildings and street arrangement, as you find in the center of many European cities.

I would really be impressed if they could automatically generate a 3D model of the three dimensional mess that is Lausanne [lausanne-webcam2.rcv.ch] :

How do they account for light/shadows (1)

DrFalkyn (102068) | more than 9 years ago | (#12463416)

The problem with these techniques is there are no algorithms I know of that account for the effect of light/shadows effectively. So the textures on your objects are going to include shadows. You can notice this effect on one of the images that have linked to in the article.

Re:How do they account for light/shadows (0)

Anonymous Coward | more than 9 years ago | (#12464200)

So they brute force it, repeat the scans at multiple times of day. The trick would be to realign the scans to account for the variation in route, but at the resolution and frequency they are using alignment with enough precision to augment results should be very possible. Multiple sweeps of the same area would then gradually improve the precision of the results.

A very few minor additional layers would greatly improve the still-shots posted on the site. 'real' streets with lane markers comes to mind as an easy upgrade with very good side effects (mapping applications with complex intersections).

maps.google.com next innovation, zoom-in to virtual street level. That would be cool.

Re:How do they account for light/shadows (1)

RichardX (457979) | more than 9 years ago | (#12464718)

Just a guess, but couldn't you tell it where the light source is in the 3D image and have it calculate the lighting/shadows (as you would in any 3D scene) - get them to match up with the shadows you observe in the image, and use that to colour correct the textures

Yahoo A9 Yellow Pages? (1)

oblique303 (848812) | more than 9 years ago | (#12463448)

I wonder how long until Yahoo's A9 search engine (or another company in a competing effort) incorporates this technology into their "Block View" street digitization project.

http://a9.com/-/company/YellowPages.jsp [a9.com]

Yahoo has been digitizing the front of buildings in major cities for some time now. It'd be great to see this imagery merged with Google's satellite view data from their KeyHole acquisition, to allow for 3d flythroughs of your favorite metropolitan area.

This could take sites like MapQuest to a new level, providing 3d photo-realistic flythroughs of your route between two locations. Sure beats reading directions!

Actually A9.com is Amazon's, not Yahoo's. Don't really see why Yahoo would make another search engine to compete with itself, anyway.

marcuspl (808826) | more than 9 years ago | (#12464296)

I understand what they mean by a "4D modelling system" and all, but is that really the most adequate term for 3D scene recording / editing? Does it even have a cool-buzz-word-hype ring to it?

Or was it called "4D Studio Max"? It has been a while since I abandoned the world of 4D editing, for good ol' simple 1D (top down yeah?) programming...

Calling it 4D is pompous.

We all know that 3D models can change over time.

This is actually rather interesting with shades of matrix. I imagine software like this will help greatly when it comes time to colonize the moon. By then we should (hopefully) have precise and comprehensive data about the environment in terms of the moons physical construction as well as radiation and space debris data. Just feed the data into the program and have a future version of this software design a habitat system almost as well (if not better) than humans could design. That could cut a decade off such an endeavor. I imagine the designs would need to be corrected here and there -- but the possibilities are fantastic.

Now imagine sending a fleet of probes to Mars consisting of an array of satellites and ground based robots that determine and design everything necessary for perminent human habitation. Imagine taking the initiative and sending such fleets throughout the solar system to all sorts of places we will want a foothold decades before mounting such complex missions. Such a system could red flag all sorts of problems with environments that would have otherwise caused a manned crew to turn around and go home. One step further: Imagine sending (even later in time) more advanced fleets that could study a place and contruct a human habitation with robots and materials before humans even left Earth to head where ever. Even further: now imagine sending such fleets to other star systems centuries before humans. The environment could assesed. Suitable structures built and pressurized with atmosphere. Everything could then be maintained by yet another group of robots for centuries or even millennia with every aspect of the greater system under the direction of planning software. Hell they could mine endless reserves of materials and chemicals that humans would want upon arrival. Alot of this would likely require advanced nanotech.

I am sure it can be taken to even greater extremes.

Game Maps? (1)

BrianRaker (633638) | more than 9 years ago | (#12470175)

How easy would it be to take this modeling infomation and to import it into one of our favorite games, such as CounterStrike or CS:Source?

Re:Game Maps? (0)

Anonymous Coward | more than 9 years ago | (#12478702)

Simple. You learn the file formats, and you write a converter in your favourite language. And yes, I do mean you.

One assumes they're using an easy-to-parse point description format, and that the textures are saved in something convenient. The game map formats are well-known or, in other cases, can be converted to from well-known formats, so it should just be data-juggling. Of course, that assumes that the game engine can happily render the metric butt-load of data that these maps use, otherwise you'll have to come up with a smoothing algorithm to ditch unnecessary vertices.
