3D Aerial Photos For the Common Man 78

Posted by samzenpus from the personal-landscapes dept.
An anonymous reader writes "So you have a RC model aircraft snapping digital photos from the air, but how do you organize them all? This cheap cloud service from a European research giant will upload your photos and automatically convert them into 3D models you can navigate like a video game. And if you don't have a model aircraft, they got those on-the-cheap too. Let the overhead droning begin!"

      It's gonna be illegal anyway, because only a terrorist or pedophile would use the technology, probably to plan out the shortest paths to bomb government buildings or rape kids at the parks.

      Even worse, the so-called "hobbyist" could use the data to make a 3-D video game about bombing government buildings or raping kids and release it under that Marxist GPL license, which would inflame tensions in the Middle East and provoke Iran into destroying Israel.

      No you didn't. Hey, I put off flapping my arms and flying to the moon in 2002, because there wasn't a decent hotel there. Or maybe I'm talking shit. Certainly that's what I assume you are doing.

      You "put it off" because neither you nor anyone else actually knows how to do it.

AI is easy to understand conceptually when you think of it as simply a computer program taking in input from the outside world, and interacting with it. The AI I'm talking about has little to no machine learning involved. It is all hard coded AI for robots to take commands and follow them. It really isn't as hard as everyone thinks.

      I'd reason that wiring up Natural Language when having a large database of objects(nouns) would still be rather difficult, but not as difficult as changing camera feeds into 3d world representation.

      With two cameras with a known separation, it's not that hard a problem at all. With one camera and a depth camera (Kinect), it's not hard at all. With one regular camera and a known motion, it's not that hard. With one camera and an unknown motion, it's a bit tricky. Mostof this is covered by Structure From Motion, or occasionally Structured Lighting.

      3D data from 2D data is a bit tricky, but nowhere even close to being as hard as software that can understand natural language. Even PARSING natural language is hard enough for most systems. There are far more systems that can map a 3D environment than there are that can correctly recognise and respond to a simple sentence, e.g: "Computer, will it be rainy today?"

      • Easier might be the wrong word, maybe more cerebral. To do natural language interpretation, I would envision you start with a "dictionary database" full of objects. These objects would be nouns, and then you could program in properties on them known as adjectives. Without a "dictionary database" of known objects, I could not figure out how to code natural language. So you're right that natural language is more difficult than digitizing things because digitized things are a component of natural language.

        • I confess that I have not read parent post while in full critical analysis mode, but I do not think that is needed here.

          All natural languages that I am aware of are based on core objects that have no physical representation. Such as "friendship", a multitude of different kinds of "love", "dishonesty", "truth", and so on. It is nearly impossible to describe anything in any human language without referencing these purely conceptual objects. The references are often buried in tacit assumptions or postulates

      No because it relies on two photos of the same thing, but taken at slightly different angles. In other words, it would work with a series of photos with some movement between them, but not with google maps since they are static.

      You might check out TFA. They have a system to sell you (no prices).Draganfly [draganfly.com] will sell you one for about 10 grand. A quick consultation with Google gives prices from $400 up. I looked into this a while back for pretty much the same reason. A decent system that could get high enough to get over trees / hills / etc. and hold a big enough camera to get reasonable resolution would be closer to the 10K than $400.

        • That just feels expensive. I have an electric RC helicopter that cost me less than $2k for the heli, radio and all the tools needed to get it to fly. I could easily attach a camera to it (even video) and stream 10+ minutes (battery life) of photo/video for a nominal added cost.

          I'm assuming that cost is quite a bit on the software/R&D side of things.

            I guess most of the cost is in R&D and software as you say, and most of the value in it working out-of-the box, autonomously. It's amazing how it looks in that video: Seems the guy just throws a piece of black cardboard in the air and the thing starts flying along a defined route.

    Several times I have seriously considered getting into doing this kind of business: aerial photos and surveys. I thought it would be both profitable and fun. And it probably is. But their "cheap" aerial reconnaissance drone costs almost $12,000.00 U.S. How much aerial surveying would it take to pay that back? A lot, I think.

    • Have you researched market opportunities? I can't imagine aerial surveys coming cheap, there must be at least several hundred dollars per deployment in there I should think

      There seem to be interesting things going on in the DIY/hobbyist sector as well. I could think of a whole range of services one could offer and for which these would be perfectly adequate.

        There are also AAAA batteries. A common 9V alkaline battery is full of them.

            In the days before LED lamps, the Fx2 (two 'F' cells, packaged) was very popular in the UK. Let the sniggering begin.

            They're still available [hitchnhike.co.uk]. Then someone thought to try making a triple pack [hitchnhike.co.uk] (inspired by Eccentrica Gallumbits) and later a pentuple [hitchnhike.co.uk] pack. (Actually, they've stopped selling those now, due to the discontinued consumer supply of NiCad cells, not because the design is "wrong" per se. They use D-cells instead. BFD.)

    • It's called a "shotgun".

  • It's hard to tell for sure because of the depth-of-field effect applied to the rendering (which I imagine was the reason they used that effect), but it seems like the quality of the model drops off dramatically the further you get from looking straight down. In the few unblurred street-level frames I caught of the high-resolution video, it's almost as though I'm looking at a clay model of the city which has had really high-quality texturemaps applied to it.

    It's still pretty cool, but I don't think anyone is

    • On their website, the sample photos from their drone are basically straight down. That would severely limit the quality of the imagery on vertical walls. I'm curious why they don't angle the camera at, say, 45*. That should allow good coverage of roofs and walls.

  • It will all boil down to what render quality costing factors are involved.
  • This could be used for:
    - games (both FPS and tactical)
    - better civil engineering planning (seeing how a project will affect its surroundings)
    - archaelogy (understanding old battlefields)
    - current military (understanding new battlefields)
    - terrorism (see "current military")
    - tourism (find hotels/other with good location)

    What other uses can we think of?
