Kinect as a 3D Scanner – reloaded

Maybe you remember some months ago Microsoft Research published information about KinectFusion, an application that allowed to incrementally digitize a 3D scene with the kinect. Until now they haven’t made this available to the public. Now some engineers have been able to reproduce the functionality and made it available for non commercial use.

ReconstructMe works on top of the OpenNI Framework and thus can also use the Asus Xtion sensor. The Application makes use of the GPU for generating the 3D data. If you don’t have a GPU powerful enough you can still process recorded data in just not in realtime then. The generated 3D scene can be exported in the STL and OBJ format.

Kinect as a 3D-Scanner

English: The Microsoft Kinect peripheral for t...

This is the coolest Kinect Hack I’ve seen so far. The project called “Kinect Fusion” initiated by Microsoft Reserach was shown at the SIGGRAPH computer graphics conference in Vancouver, B.C., and you can see it in the video below. With that integrated into a mobile device AR really would start to make sense. Interesting also that you should be able to increase the resolution of the scan by scanning the scene multiple times.

Engadget has some more Details on the Presentation given at SIGGRAPH.

Solutions for HDMI 1.4a conversion

If you deal with 3D Stereo Video sooner or later you will have to find a solution for the HDMI 1.4a problem as of today there are only very little devices available that support it. This format for example used by Blu-Ray 3D or the Sony Playstation to play out 3D video, sends the left above the right eye image in one frame without anamorphic compression.

If your display device does support it or if you have a setup with two video projectors where you need left and right eyes in two separate signals you have to convert somehow. As of today I only know of two devices that are capable of that.

For a conversion to 120Hz stereo this is the Optoma 3D-XL. It converts HDMI 1.4a as well as Side-by-Side stereo video.

For conversion to Side-by-Side and to two separate stereo signals it’s the rather pricy Corio C2-8000 series full fledged seamless switchers from tvone that became available at ISE 2011. I’ve had the chance to test the C2-8110 that comes with 6 HDMI 1.4a capable inputs and two outputs.

3-D Models Created by a Cell Phone

Capturing an object in three dimensions doesn’t require the budget of Avatar. A new cell phone app developed by Microsoft researchers can be sufficient. The software uses overlapping snapshots to build a photo-realistic 3-D model that can be spun around and viewed from any angle.

Another company providing a similar solution is 3Dmedia.

Just landed – Realtime Infographics

Interesting concept.

From the author:

I was discussing H1N1 with a bioinformatics friend of mine last weekend, and we ended up talking about ways that epidemiologists model transmission of disease. I wondered how some of the information that is shared voluntarily on social networks might be used to build useful models of various kinds.

I’m also interested in visualizing information that isn’t implicitly shared – but instead is inferred or suggested.

This piece looks for tweets containing the phrases ‘just landed in…’ or ‘just arrived in…’. Locations from these tweets are located using MetaCarta’s Location Finder API. The home location for the traveling users are scraped from their Twitter pages. The system then plots these voyages over time.
