What’s going on

Code of markerless tracker is finished for emulator. It’s in in minimal configuration, without some optimizations, bell and whistles like combined points-edge pose estimation for now. Now it’s bugs squashing and testing with different video feeds for some times. Modified bundle adjustment is the nicest part, seems pretty stable and robust.

Marker vs markerless (bundle adjustment)

#augmentedreality
Here is a sample of image registration with fiduciary marker (actually the marker I used in my games) vs registration with bundle adjustment. Blue lines are points heights (relatively to marker plane) calculated using marker registration and triangulation. White lines are the same using bundle adjustment(modified). Points extracted with multiscale FAST and fitted with log-polar Fourier descriptors for correspondence (actually SURF descriptor produce the same correspondence).
marker vs markerless
As you can see markerless is in no way worse then markers, at least on this example ))).
