In standard solution of using Image Based Lighting (IBL) in AR all images are captured from single digital camera (low dynamic range – LDR). Using High Dynamic Range (HDR) and IBL in AR environment increase knowledge about lighting calculation and extraction of the strongest light sources. In first chapter introduction to lighting virtual objects in AR environment was presented. Second chapter present AR and main claims put for AR systems. Chapter “High Dynamic Range Images” show general issues of HDR technique. In chapter four technique of calculate lighting from an image of the environment was presented. Next chapter present lighting virtual object in AR environment with using HDR images. Last chapter present conclusion about using HDR images to lighting virtual objects in AR environment.
