This is SLAM AR with ZED Stereo Camera on Ubuntu 14.04.
It runs as MarkerLess-AR mode at first, press 'space' button to start SLAM-AR mode.
This is the demo video: http://v.youku.com/v_show/id_XMTU2Mjk1MjMyOA==.html?spm=a2hzp.8253869.0.0
During the video, it is running on my Mac, without using ZED Stereo Camera.
I used a stereo camera made by myself.
If you want to make your own stereo camera, you need to calibrate your camera and use your own camera parameters.
Besides, if you want to make it work on monocular, you can check ORB_SLAM2 for updates.
