MultiprojectorTiledDisplay

Predominantly, this code is an implementation of the multiprojector geometric alignment and edge blending approaches proposed here. Futher, we have proposed and implemented an approach for enhancing the overall projection resolution by utilizing the perspective projection invariant, cross-ratio. Code has been tested for only one planar projection region configuration till now, a 3X3 multiprojector setup. Work on GUI development and addressing arbitrary tiled configurations is under progress.

Current limirations

• Hard-coded configuration(see, sl_multiproj.cpp)
• Tested on older OpenCV only(v2.4)
• Assumes gPhoto2 supported camera

Dependecies

• OpenCV
• gPhoto2
• Qt(soon...)

Build

mkdir build
cd build
cmake ../
make

Documentation(Not generic)

• Running calibration
• Applying calibration settings
• Addendum

TODOs

• GUI
• User manual(for hackers, sl_multiproj.cpp contains the core implmentation)
• File(or, GUI)-based configurability
• Extension of the code for arbitrary planar multiprojector arrangements
