This program corrects the keystone distortion of a projector automatically.
It detects the surface that projected onto and find its equation.
Plane detection is done by using OpenARK library (https://github.com/augcog/OpenARK) \

To run this program
Build it by using given CMakelist.
It requires OpenCV, Boost, and Royale library to connect PMD pico-flexx camera.
After build it, connect your projector and camera.
And run by command ./keystone
You can specify the exposure times ./keystone -e 100
If exposure is not specified, auto-exposure mode is used
In order that plane detection works, auto-exposore mode is suggested. \
