@brief?A?simple?augmented?reality?example?application.

This?application?estimates?the?intrinsic?calibration?and?camera?pose?for?the?frames?of?an?input?video?sequence?in?relation?with?a?template?pattern.

The?application?detects?the?following?template?on?the?input?frames:

@image?html?template.png
@image?latex?template.png

Each?frame?the?planar?homography?which?maps?the?original?pose?of?the?template?to?its?location?is?estimated.
If?successful?the?application?obtains?the?camera?pose?and?an?estimation?of?the?camera?focal?distance?from?this?homography.
By?averaging?these?focal?values?a?robust?estimation?for?the?camera?calibration?is?obtained.

A?standard?image?canvas?augments?the?input?frames?with?an?artificial?object?using?the?estimated?camera?pose?and?intrinsic?calibration:
