Global common illumination between real and virtual objects is the process of illuminating scenes and objects with images of light from the real world. After including the virtual objects, the resulting scene should have consistent shadow configuration. This paper presents a novel algorithm that integrates synthetic objects in the real photographs by using the radiosity on graphics processing unit (GPU) and high dynamic range (HDR) radiance map. In order to reconstruct 3D illumination environment of the scene, we estimate the camera model and the extrinsic parameters from omni-directional images. The simulation results showed that our method can generate photo-realistic images.
