I was actually beginning work on a similar project. Essentially, it's using a combination of the accelerometer and the gyro to get the phone's position in 3D space. That is, when the accelerometer capture lateral velocity, it knows it's moving in a certain direction at a certain speed (until, of course, it receives an opposite velocity, at which point it stops).

Did you ever manage to get it to be accurate, though? I tried something similar but the accelerometer and gyro were nowhere near accurate enough.

Not even close. I was approaching the filtering mechanisms before I started a new job and started focusing my efforts on that.

I don't think we're quite at the point where a mobile CPU would be able to pull this off, however filming and uploading a well shot video to a server for further processing should be a workable way to make a full model. I think a big challenge there is a several-minute feedback loop to learn if it worked and if you need to try it again.

I built an Android app, Forge, that does just that. No feedback loop needed - the reconstruction is streamed back to you as you go: http://aboundlabs.com

Is monocular SLAM good enough nowadays that this can be done without depth cameras, just from a single camera?

I was talking about monocular SLAM (although since it's not really simultaneous... ALAM?)

Parent has a cool product too, as does http://structure.io/ - but that's not what I meant.

Here's an alternative with a more interactive work flow: http://magic-plan.com/ .

That seems to work a little better for me in terms of accuracy. This approach is different in that this is using a fixed eye position and overlay measure on the camera image and then working out the arctangent etc. Clever.

And your laser tape translates those measurements into a floorplan that's digitally sharable?

My HOWTO: 1. Obtain laser tape, pencil, and paper. 2. Sketch out floor plan with pencil on paper in rough scale. 3. Take laser tape and take needed measurements. Annotate measurements on your rough scale paper drawing. 4. Go back to desk and open OmniGraffle (or Visio or whatever). 5. Draw up a scale floorplan, exportable into any needed, industry standard formats. 6. There is no step 6. Some variation of this HOWTO…

How to start a startup: Find a process that requires tedious work with lots of different tools, and make that process simpler and easier. Start with something that works well enough to be of value to some people, and improve until the old process is laughably complex.

This app seems valuable to non-professionals who may want a digital floorplan of a room. Since you are a professional with 20 years of experience, you have an established workflow, and know how to deal with the variations.

Experts will often be able to out-perform automated solutions, which is fine. Those automated solutions are for non-experts.

I hoped that either they got their hands on Project Tango device or worked with this team in Zurich - http://www.i-programmer.info/news/192-photography-a-imaging/... Edit: Btw, anyone who applied for Project Tango got back from them in any way? I didn't.

We heard back and got a device last week.

Quite disappointed - was hoping this was done through computer vision. Aren't there are apps that do this? By the time I've 'scanned' a room the way it's shown in the article, and if that method doesn't even give me heights, doors, windows and outlets, and is only accurate to within half a foot - by that time I've measured it with my laser tape measure 3 times over.

Would Leap Motion or Kinect be able to do something like this? They basically detect physical objects in space so shouldn't they be able to 3D map a space? I know the current Leap device has a limited view area but I understand that's just a design decision for that particular device.
