Knowledge about illumination conditions in a real world scene has many applications, among them Augmented Reality which aims at placing virtual objects in the real world. An important factor for convincing augmentations is to use the illumination of the real world when rendering the virtual objects so they are shaded consistently and cast consistent shadows. This paper provides an overview of several lightning technics and proposes enhancements of real-time image based lightning system for outdoor augmented reality under dynamically changing illumination conditions. Proposed improvements help to increase speed and quality of rendering.
