It seems that ARkit is actually using SLAM as the core technology (in parts, the same technology is being used in autonomous cars and navigating drones). Getting it to work on mobile phones is quite challenging and had been the subject of much research in recent years, some good starting points (with code): ORB-SLAM - https://github.com/raulmur/ORB_SLAM2 https://github.com/raulmur/ORB_SLAM2, https://www.youtube.com/watch?v=T-9PYCKhDLM https://www.youtube.com/watch?v=T-9PYCKhDLM DSO - https://github.com/JakobEngel/dso https://github.com/JakobEngel/dso, https://www.youtube.com/watch?v=C6-xwSOOdqQ https://www.youtube.com/watch?v=C6-xwSOOdqQ VINS - https://github.com/HKUST-Aerial-Robotics/VINS-Mobile https://github.com/HKUST-Aerial-Robotics/VINS-Mobile, https://www.youtube.com/watch?v=0mTXnIfFisI&feature=youtu.be https://www.youtube.com/watch?v=0mTXnIfFisI&feature=youtu.be (the last one being released just a few days ago...) Of course there are a lot more resources out there and a lot of the cutting edge research is involved with deep learning techniques (starting with e.g. https://github.com/alexgkendall/caffe-posenet https://github.com/alexgkendall/caffe-posenet). You may also want to watch out for this conference http://cvpr2017.thecvf.com/ http://cvpr2017.thecvf.com/ scheduled for the end of this month and is usually a good source of cutting edge research...
