Calibrated computer graphics: a new approach to realistic image synthesis based on camera calibration

Camera calibration is an important issue not only for real image analysis but also for realistic image synthesis. This paper proposes a new scheme for image synthesis that we call “calibrated computer graphics” and presents a method to synthesize blurred images based on camera parameters obtained by calibrating a real camera. Using the reversed projection blurring model, we have developed the multiple Z-buffer algorithm to generate images of arbitrary focus settings. Experimental verification has demonstrated that the quality of reality of the generated images is as high as that of real images. Finally, we have shown a series of synthesized images that include virtual objects embedded in real images
