An overview of occlusion issues handling in Augmented Reality≫

摘要: Résumé Augmented reality is a field related to superposition of virtual elements in a real environment. As Ronald Azuma has mentioned, one important feature of augmented reality is real-time interaction not only with a user but also between real and virtual objects. So the user has to manipulate some virtual entities the same way he would do with real ones. However, manipulation errors and cognitive problems may exist due to misguiding depth clues. This misperception is often caused by occlusion issues which are not managed or solved by several augmented reality systems. In this paper, we will present a brief survey of how occlusion and interpenetration issues are tackled and solved in augmented reality systems. Some occlusion refining solutions which improve realistic rendering are also presented in this paper. Finally, we compare the use conditions of each method and make a list of their strong points and …
