Abstract

Many game development frameworks have become supporting Augmented Reality (AR) games using cameras and depth sensors embedded in smartphones. In most cases, they detect horizontal and vertical planes such as tabletops or walls in a room at first, and put virtual game characters and props on the faces. 2D markers are currently widely used for making virtual items over real-world gadgets. For sharing the playing game data between multiple devices, data sharing of the game world is also supported. Such the face detection function, 2D marker recognition, and the world sharing mechanism are the main features of the AR game support. However, in the recent situation that 3D printers are rapidly becoming popular all over the world, 3D markers might be important technology for AR game development. In this paper, we introduce a simple yet powerful method for 3D marker recognition that can be flexibly used in AR games.
