GPU-accelerated stereo processing on Tegra X1

This is a ROS implementation of Embedded real-time stereo estimation via Semi-Global Matching on the GPU, D. Hernandez-Juarez et al, ICCS 2016. Code: https://github.com/dhernandez0/sgm D. Hernandez-Juarez

It rectifies raw images given a calibrated stereo camera and publishes disparities and pointclouds.
