Simple real-time stereo implementation using CUDA. This is a baseline method that uses NCC and 2D averaging. Your mileage may vary.
The main stereo code can be found in src/StereoMatcher.h src/StereoMatcher.cc. It requires cudaArray (https://github.com/trueprice/cudaArray).
Executables are located in src/calibration.cc (for calibrating the stereo rig using a checkerboard) and real_time_stereo.cc. These programs require OpenCV (http://opencv.org/) and the FLIR FlyCapture SDK (https://www.ptgrey.com/flycapture-sdk).
