| Abstract(in English) | This paper deals with a method to calibrate the photo picture taken by the 35mm single-lens reflex digital camera attaching a fish-eye lens. In this paper, we call usual camera lens as the normal lens that maps a straight line into a straight line. We propose a method by that we can make the images of the virtual normal lens from pictures taken by a fish-eye lens. At first, we present an identification method of the projection type of the fish-eye lens used for our experiment. Next, we derive the conversion formula from the virtual normal lens picture to the fish eye-lens image. In order to show the effect of the proposed method we compare the actual pictures taken by the f20mm, f28mm, f50mm, f200mm lens and the calibration pictures by the present method for equivalent focal length. |
