This is iOS port of ORB-SLAM2 with modified dependency for iOS.

And this link is iOS port of ORB-SLAM1.

You need to download some dependency and opencv2.framework from https://pan.baidu.com/s/1i5fsyot

Unzip orbslam2ios.zip and put the dependency folder and opencv2.framework in the orbslamios folder.

You can do some AR projects. If you are interested in SLAM-AR, you can see my another project Stereo-SLAM-AR.
