Apple is releasing ARKit 1.5 to developers, which gives them tools to turn posters, signs and artwork into AR experiences.In addition to horizontal surfaces like tables and chairs, ARKit can now recognize and place virtual objects on vertical surfaces like walls and doors and can map irregularly shaped surfaces like circular tables.

Using computer vision techniques to find and recognize the position of 2D images such as signs, posters, and artwork, ARKit can integrate these real-world images into AR experiences such as filling a museum with exhibits or bringing a movie poster to life.
