360 degree photographs and 3D

April 12, 2011 Leave a comment

360 degree photographs have been around for quite a while. Here’s a hi res image of St Pauls Cathedral.

The problem is of course that you can only see everything from the position of the camera. I got to thinking how neat it would be if you could actually move around the image and see things from different points of view. This would of course require that you take millions of 360 degree pictures from pretty much every physical point within the area you are photographing. Not entirely practical.

But then I got to thinking about the sort of technology being used by numerous people in conjunction with the Microsoft Kinect to generate 3D images. Some cleaver mapping software lets the the viewer see things from points other than the Kinnct’s physical location.

So here’s my thought. Merge 360 degree photography with the 3d software being used by Kinect hackers to generate a virtual 3d environment. You would only need a limited number of actual 360 degree photographs in order to dynamically recreate a 3d space by dynamically generating the view for points between the actual photographs.

Some thoughts on 3D

A recent post by Sandy Carter on her blog about the Avatar movie and 3D effects got me thinking a little about 3D. Right now there’s a lot of buzz about 3D and I will admit that it’s pretty cool, or at least the Avatar movie was although I’m not sure if the success of the movie is a result of the use of 3D, the quality of the graphics or maybe a bit of both.

Anyway, one thing that has occurred to me is that what these 3D effects give us is really only enhanced depth perception. Whilst that is great, we still only have a single point of view of the image. IE, that of the camera. We can no more move around this so called 3D image than we can with a regular flat image, be it screen, paper or whatever.

OK, now lets looks at virtual worlds. These give us the ability to move around in a three dimensional world but we interact with it through a two dimensional medium (I bet you can see where I am going with this can’t you?).

So what would happen if we could merge the two. Three dimensional virtual worlds with true 3d depth perception. That would be pretty cool, Imagine playing say Halo in 3D.

But, let’s not stop there. Right now there’s a lot of interest in augmented reality (AR) where digital imagery is overlaid over a real world video view to provide an enhanced experience as show in this demo of the London Underground. So what would happen if instead of using a separate 2D device like the iphone, you were to use 3D depth perception technology (the geeky glasses) to overlay AR data onto the real world. Consider for instance gaming. Instead of being locked to the computer or HD TV, you could actually play say Halo or Modern Warfare or any number of first person games in the real world with the other payers and computer generated imagery being overlayed, in 3 dimensions onto your real world. Instead of sitting in front of a TV or computer all day, kids might actually go out and play. Imagine the health benefits alone from that.
