This paper proposes a novel 3-D modeling technique of an object. The existent 3-D modeling techniques such as stereo vision or the factorization recover 3-D shapes of part of an object observed commonly from multiple orientations. This inevitably needs registration among recovered partial shapes in order to obtain an entire 3-D model of the object. The proposed technique recovers entire shape of an...
In this paper, a novel camera parameters calibration algorithm is proposed by exploiting defocus information. The proposed algorithm is based on two defocus images of the same scene obtained by changing camera's aperture numbers. Both images can be arbitrarily blurred. The blur difference between the two defocused images was estimated. Combining with imaging geometry of the thin lens, the corresponding...
