Dual boot Android on N900?

Well, that spectacular, to say the least. Wondering if camera/opengl drivers would work.

I want smartphone with stereocamera

#augmentedreality
Smartphone with stereocamera is not exactly a new concept
Motorola stereo camera phone
But 3d registration, rangefinding, augmented reality would be a lot more robust and efficient with stereocamera.
Of cause it should be implemented properly, distance between lenses should be as big as possible. Preferably with lenses near opposite ends of the phone, to increase baseline, which would increase 3d precision.
Special geek model could have second camera on the retractable extender for even more precision.
Stereocamera would make AR markerless tracking trivial. 3d structure of the scene could be triangulated in one step form the single stereoframe.

More bundle adjustment

Here is some more narrow baseline local bundle adjustment, from only two camera frames.

Outlier is drawn in red. Some points are not detected as outliers, but still are not localized properly.
Multiscale FAST used for detection. No descriptors were used for point correspondence, instead incremental tracking with search in sliding window by average gradient responses was used(there are three tracked frames between those two). I think those bad points could possibly be isolated with some geometric consistency rules, presuming landscape is smooth.
